Plant a Seed in every classroom

Posted on December 1, 2008 by Bora Zivkovic | 1 comment

Now you can donate a subscription to Seed Magazine to a classroom of your choice:

Earlier this year, as part of the DonorsChoose Blogger Challenge, ScienceBlogs readers donated over $18,000 toward science literacy.
Seed Media Group was proud to donate a further $15,000, bringing the ScienceBlogs community’s total contribution to over $33,000. Schools around the nation are already putting these badly-needed funds toward science classrooms and labs.
Science literacy is a crucial element in driving progress. We believe that by providing the next generation access to scientific perspectives, by introducing them to the stories of how we, our world, and our universe work, we are handing them the first critical tools to help build a healthy, prosperous future.
In the spirit of the DonorsChoose Blogger Challenge, we are offering the chance to give the gift of science year-round. Donate a Seed magazine subscription to a science classroom and we’ll give you the base subscription price of $14.95. You may donate one or more subscriptions to a school (or schools) of your choice, or, if you do not have a specific school in mind, DonorsChoose has selected schools that are most in need of these donations and will happily choose one for you.
We’re proud of the ScienceBlogs community, and of what we’ve been able to achieve together for science education. Thank you!

New and Exciting in PLoS this week

Posted on December 1, 2008 by Bora Zivkovic | Comments Off

Let’s see what is new in PLoS Medicine, PLoS Biology and PLoS ONE today:
Time-of-Day-Dependent Enhancement of Adult Neurogenesis in the Hippocampus:

Adult neurogenesis occurs in specific regions of the mammalian brain such as the dentate gyrus of the hippocampus. In the neurogenic region, neural progenitor cells continuously divide and give birth to new neurons. Although biological properties of neurons and glia in the hippocampus have been demonstrated to fluctuate depending on specific times of the day, it is unclear if neural progenitors and neurogenesis in the adult brain are temporally controlled within the day. Here we demonstrate that in the dentate gyrus of the adult mouse hippocampus, the number of M-phase cells shows a day/night variation throughout the day, with a significant increase during the nighttime. The M-phase cell number is constant throughout the day in the subventricular zone of the forebrain, another site of adult neurogenesis, indicating the daily rhythm of progenitor mitosis is region-specific. Importantly, the nighttime enhancement of hippocampal progenitor mitosis is accompanied by a nighttime increase of newborn neurons. These results indicate that neurogenesis in the adult hippocampus occurs in a time-of-day-dependent fashion, which may dictate daily modifications of dentate gyrus physiology.

Mutualistic Interactions Drive Ecological Niche Convergence in a Diverse Butterfly Community:

What governs the composition of communities of species? Competition promotes divergence in behavior and habitat, allowing species to co-exist. But the effects of other interactions, such as mutualism, are less well understood. We examined the interplay between mutualistic interactions, common ancestry and competition in mimetic butterflies, one of the best studied examples of mutualism, in which species converge in wing pattern to advertize their toxicity to predators. We showed that mutualism drives convergence in flight height and forest habitat, and that these effects outweigh common ancestry (which should lead related species to be more similar) and competition (which promotes ecological divergence). Our findings imply that species that benefit from one another might evolve to form more tightly knit local communities, suggesting that adaptation is a more important process affecting community composition than is commonly suspected. Our results also support the idea that mimicry can cause speciation, through its multiple cascading effects on species’ biology.

The Prevalence of Mental Disorders among the Homeless in Western Countries: Systematic Review and Meta-Regression Analysis:

There are well over a million homeless people in Western Europe and North America, but reliable estimates of the prevalence of major mental disorders among this population are lacking. We undertook a systematic review of surveys of such disorders in homeless people. We searched for surveys of the prevalence of psychotic illness, major depression, alcohol and drug dependence, and personality disorder that were based on interviews of samples of unselected homeless people. We searched bibliographic indexes, scanned reference lists, and corresponded with authors. We explored potential sources of any observed heterogeneity in the estimates by meta-regression analysis, including geographical region, sample size, and diagnostic method. Twenty-nine eligible surveys provided estimates obtained from 5,684 homeless individuals from seven countries. Substantial heterogeneity was observed in prevalence estimates for mental disorders among the studies (all Cochran’s χ2 significant at p 85%). The most common mental disorders were alcohol dependence, which ranged from 8.1% to 58.5%, and drug dependence, which ranged from 4.5% to 54.2%. For psychotic illness, the prevalence ranged from 2.8% to 42.3%, with similar findings for major depression. The prevalence of alcohol dependence was found to have increased over recent decades. Homeless people in Western countries are substantially more likely to have alcohol and drug dependence than the age-matched general population in those countries, and the prevalences of psychotic illnesses and personality disorders are higher. Models of psychiatric and social care that can best meet these mental health needs requires further investigation.

What’s wrong with Google Blogsearch?

Posted on December 1, 2008 by Bora Zivkovic | 2 comments

Checking one’s incoming links on Sitemeter, Technorati and Google Blogsearch is essential tool for a blogger – it allows one to notice responses to one’s posts in approximately real time, so the blog-to-blog conversation can continue fluently.
But, for a couple of weeks now, Google Blogsearch has been useless. They have changed the algorithm so, instead of picking up only links from individual blog posts, it picks up links from all sorts of widgets, blogrolls, etc. and thus floods the search with tons of useless hits. I have no idea who just posted a blog response to something I said, and who just updated the blog and the blogroll got updated with it.
This is more than useless. Anyone at Google listening? I am sure they must be flooded with protest messages! How hard it would be to revert to the old algorithm while working on a better one behind the scenes?

Twilight

Posted on November 30, 2008 by Bora Zivkovic | 5 comments

Saw the movie over the weekend. Mrs.Coturnix and Coturnietta read the first book (Coturnietta is now reading the second) so we went together.
I am a horrible movie critic – I usually kick back, munch popcorn, and enjoy every piece of crap on the screen. Heck, I love B-monster movies.
So, back to Twilight – first, it was obvious it was a movie made after a book:
– it was too long (Hollywood makes them 90min by design)
– it was choppy and the story was overcomplicated (Hollywood makes simple storylines by design)
– it was missing relevant information, probably something explained in the book, but not possible to turn to the screen.
OK, so this place is, like, in the middle of nowhere and has population of 1200 and some change. That ‘change’ must be the few adults, as the high school looks like it houses about 1200 students (it was actually a Seattle suburb school where it was filmed), so almost all inhabitants must be high-schoolers.
For a place that small, the school is amazingly big, clean, bright and well-equipped. For a place that small, the diversity is amazing – just the right mix of whites, blacks, Asians, Native Americans and vampires. For a place that small, stats would suggest a total of about 2-3 prettier-than-normal people, but here, every single person is gorgeous – every guy is super-handsome and every woman is stunningly beautiful. Nobody’s fat. Nobody’s ugly. Nobody’s just, you know, normal!
Also, the movie is constantly reminding us how the two main protagonists are hawt, and self-aware about their hawtness, and self-confident about their hawtness, and too busy with their adventure to pay much attention to the mere mortals around them. But there was just a small hint (the scene in the biology lab in which they won an onion) that they are also very smart and educated. I asked Mrs.Coturnix and she confirmed that the books stress this a lot, while the movie completely omits their intelligence.
I checked the IMBD afterwards to see who all those super-beautiful actors were as only one or two seemed familiar. Apparently they all have nice long careers on TV (which I don’t watch), the guy who plays Edward also plays Cedric Diggory in Harry Potter movies, the actor who plays the Dad was in a lot of B movies, and the main actress played the daughter as a kid in Panic Room which I loved (so I could not recognize her at all). Apparently, the two main actors each got $2mil for this movie, and will get $12mil for the second one.
Oh, but I loved it, did I tell you that?

If you are a University, Open Access is cheaper

Posted on November 29, 2008 by Bora Zivkovic | Comments Off

Philip Johnson makes some back-of-the-envelope calculations, very conservatively assuming that all OA journals are author-pay (not true) and all author fees for publishing are born by the Universities (not true) and concludes that even with such harsh handicapping, universities that switched to OA-only policies would immediately save substantial amounts of money (also check the excellent comments on that post):

Subscription costs would obviously be nil for an open access journal: we are all free to access the content of an open access journal via the internet, with no restrictions on who can read the content. In contrast, the author would pay to publish the article. This is perhaps the biggest resistance from scientists (and I’m sure the situation would be similar in the arts, or law, or what have you) to the open access movement, many feeling they don’t have enough funding for students or experimental equipment as is, and couldn’t possibly afford to pay to publish as well. I can appreciate this argument, though some progress is being made as you can specifically request funding to cover open access publication charges from some of the granting agencies.
(Also, let’s be honest, the current situation of paying for page charges and to have colour figures means the author is already paying to publish, and sometimes non-trivial amounts.)
————————
Let’s further assume that the economies of scale would kick in if universities around the world decided to embrace this philosophy. This should lead to an overall lowering of the publication costs, all the while bringing access to academic literature to everyone with an internet connection. It is also easy to imagine the costs being even lower, as the collaborative nature of academic work means many papers now have authors from multiple institutions, all of whom could share in the cost of publishing. (Determining the rules for who-pays-what would be tricky, but should be doable.)
There are probably some key issues I’m missing here (the most obvious one which I’ve even mentioned is that we need open access journals to publish in!), and my idea is prefaced on the assumption that universities are the significant driving force in the academic literature game, but I think the take-home message is reasonably clear, at least using the University of Toronto numbers: we could already afford going entirely open access.
I certainly wouldn’t feel bad if Elsevier and their ilk went out of business given the exorbitant increase in subscription costs and the non-obvious reasoning why, and I’m sure the societies could come to embrace the open access movement, which would bring the majority of high quality journals into the fold.

Peter Suber adds some useful links and calculations, including:

# Since November 2006 several studies have give us newer data on the the ratio of no-fee OA journals to fee-based OA journals. The best current estimates are that 67% of the journals listed in the DOAJ charge no publication fees, and 83% of OA journals from society publishers charge no publication fees. Clearly if Johnson zeroed out the publication fees for two-thirds of the articles published by Toronto faculty, the projected saving would rise significantly.
# The bargain would be even more compelling if we could subtract the publication fees paid by funding agencies rather than universities. Unfortunately there are no studies yet estimating that number.

Why does Impact Factor persist most strongly in smaller countries

Posted on November 28, 2008 by Bora Zivkovic | 13 comments

The other night, at the meeting of the Science Communicators of North Carolina, the highlight of the event was a Skype conversation with Chris Brodie who is currently in Norway on a Fulbright, trying to help the scientists and science journalists there become more effective in communicating Norwegian science to their constituents and internationally.
Some of the things Chris said were surprising, others not as much. In my mind, I was comparing what he said to what I learned back in April when I went back to Serbia and talked to some scientists there. It is interesting how cultural differences and historical contingencies shape both the science and the science communication in a country (apparently, science is much better in Norway, science journalism much better in Serbia).
But one thing that struck me most and got my gears working was when Chris mentioned the population size of Norway. It is 4.644.457 (2008 estimate). Serbia is a little bigger, but not importantly so, with 7.365.507 (2008 estimate – the first one without Kosovo – earlier estimates of around 10 million include Kosovo). Compare this to the state of North Carolina with 9,061,032 (2007 estimate).
Now think – what proportion of the population of any country are active research scientists? While North Carolina, being part of a larger entity, the USA, can afford not to do some stuff and do more of other stuff, small countries like Norway and Serbia have to do everything they can themselves, if nothing else for security reasons, e.g., agriculture, various kinds of industry, tourism, defense, etc. Thus, North Carolina probably has a much larger percentage of the population being scientists (due to RTP, several large research universities, and a lot of biotech, electronics and pharmaceutical industry) than an independent small country can afford (neither Norway nor Serbia are members of the EU).
So, let’s say that each of these smaller countries has a few thousand active research scientists. They can potentially all know each other. Those in the same field certainly all know each other. Furthermore, they more than just know each other – they are all each other’s mentors, students, lab-buddies, classmates, etc., as such a country is likely to have only one major university in the capital and a few small universities in other large cities. It is all very….incestual.
With such a small number of scientists, they are going to be a weak lobby. Thus, chances of founding new universities and institutes, expanding existing departments and opening up new research/teaching positions in the academia are close to zero. This means that the only way to become a professor is to wait for your mentor to retire and try to take his/her place. This may take decades! In the meantime, you are forever a postdoc or some kind of associate researcher etc.
If each professor, over the course of the career, produces about 18 PhDs (more or less, depending on the discipline) who are indoctrinated in the idea that the academic path is the only True Path for a scientist, the competition for those few, rare positions will be immense. And they all know each other – they are all either best friends or bitterest enemies.
This means that, once there is a job opening, no matter who gets the job in the end, the others are going to complain about nepotism – after all, the person who got the job (as well as each candidate who did not) personally knows all the committee members who made the final decision.
In such an environment, there is absolutely no way that the decision-making can be even the tiniest bit subjective. If there is a little loophole that allows the committee to evaluate the candidate on subjective measures (a kick-ass recommendation letter, a kick-ass research proposal, a kick-ass teaching philosophy statement, kick-ass student evaluations, prizes, contributions to popularization of science, stardom of some kind, being a member of the minority group, etc.), all the hell will break loose at the end!
So, in small scientific communities, it is imperative that job and promotion decisions be made using “objective” (or seemingly objective) measures – some set of numbers which can be used to rank the candidates so the candidate with the Rank #1 automatically gets the job and nobody can complain. The decision can be (and probably sometimes is) done by a computer. This is why small countries have stiflingly formalized criteria for advancement through the ranks. And all of those are based on the numbers of papers published in journals with – you guessed it – particular ranges of Impact Factors!
Now, of course, there are still many universities and departments in the USA in which, due to bureacratic leanings of the administration, Impact Factor is still used as a relevant piece of information in hiring and promotion practices. But in general, it is so much easier in the USA, with its enormous number of scientists who do not know each other, to switch to subjective measures, or to combine them with experiments with new methods of objective (or seemingly objective) measures. From what I have seen, most job committees are much more interested in getting a person who will, both temperamentally and due to research interests, fit well with the department than in their IFs. The publication record is just a small first hurdle to pass – something that probably 200 candidates for the position would easily pass anyway.
So, I expect that the situation will change pretty quickly in the USA. Once Harvard made Open Access their rule, everyone followed. Once Harvard prohibits the use of IF in hiring decisions, the others will follow suit as well.
But this puts small countries in a difficult situation. They need to use the hard numbers in order to prevent bloody tribal feuds within the small and incestuous scientific communities. A number of new formulae have been proposed and others are in development. I doubt that there will be one winning measure that will replace the horrendously flawed Impact Factor, but I expect that a set of numbers will be used – some numbers derived from citations of one’s individual papers, others from numbers of online visits or downloads, others from media/blog coverage, others from quantified student teaching evalutions, etc. The hiring committees will have to look at a series of numbers instead of just one. And experiments with these new numbers will probably first be done in the USA and, only once shown to be better than IF, transported to smaller countries.

What is wrong with the picture?

Posted on November 27, 2008 by Bora Zivkovic | 11 comments

Serbian Ministry of Health, as part of their fight against AIDS, inserted a condom inside a women’s magazine this month. The condom is German-made, named “Bumper-Bumper” and in a fun-looking package:

[Image from]
The timing is unfortunate (I’m sure it was planned months in advance and was too difficult to pull back at the last moment) – this was mailed out just 2-3 days after a guy in Belgrade killed his wife – a pretty brutal case of domestic violence that everyone is talking about (this is not something that happens often there).
Question #1: Why are condoms not sent to men? Are the guys there not reading any magazines? Sports? Tech? I am sure there is some research that shows that this is more efficient, but aren’t the guys those who should care of this thing?
Question #2: what is wrong with the picture?

ScienceOnline’09 – Friday events

Posted on November 27, 2008 by Bora Zivkovic | 1 comment

The Friday page for the ScienceOnline09 is not up to date yet, but will be soon.
What is planned?
In the morning, there will be something related to coffee – Coffee Science of sorts. Place and time TBA.
For lunches, you are free to organize yourselves by editing the Friday page.
In the afternoon, we will have a set of Lab Tours starting at 2:30pm and ending around 4pm. BRITE and NC Museum of Natural Science are already set in stone. Several others are still in the process of finalizing the details (e.g., how many participants, etc.). We will soon have the complete list up on the wiki so you can start signing up for them.
The evening program will start with a Friday Fermentable (at Sigma Xi) with these guys (yes, listen to the whole show – it is worth your time) at around 6:00pm. The sign-up page will come up for this soon as well.
Then, WiSE takes over at 6:45pm with registration and a Networking/appetizers/local groups fair event, i.e., come to eat, drink and schmooze. At 8pm, we’ll get into the big room for The Big Speech of the conference – by Rebecca Skloot. Title is still TBA, but it will have something to do with science, women in science, careers and science communication.
Afterwards, I guess we’ll all move accross the road to Radisson bar for some more drinks.
Keep an eye on the Friday page for all of the details over the next several days.

Science and Science Fiction

Posted on November 26, 2008 by Bora Zivkovic | Comments Off

A few days ago, Peggy and Stephanie asked the blogosphere a few questions about the relationship between science and Science Fiction. They want to use the insights from the responses to run their session – Science Fiction on Science Blogs – at the ScienceOnline09 meeting in January.
They got lots of responses – interesting reads for the long holiday weekend:
Responses from the SF Writer Point of View

Responses from the Science Point of View

There’s also discussion of the topic going on at io9.
I did not find time (yet) to write my own responses. Perhaps I will – no promises, as I may feel, after reading everyone else’s posts, that I have nothing to add. In the meantime, you can check out (if you have missed them before) some of my old posts related to Science Fiction:

Ten things to know if you’re having Thanksgiving with Republicans

Posted on November 26, 2008 by Bora Zivkovic | 1 comment

Here – a compilation of ten facts:

Congratulations, liberal/progressive/terrorist! This is the first Thanksgiving in eight years where you represent the political majority. Because you know who voted with you? Oh, just fifty-three percent of the United States of America. HELL YEAH! Who’s a member of the fringe lunatic this holiday season? Not you!
But what happens if your right-wing relatives still want to debate the outcome of the election? Defang your conservative loved ones with these ten helpful facts!:

But since when are facts supposed to be of any interest to Republicans? Their modus vivendi is to ignore the facts, “make their own reality”, then get surprised when Reality hits them in the face (see: Katrina, Iraq, financial meltdown, etc.).

What do you think? I think he has not seen change.gov and change.org yet, as they undermine his (otherwise useful) argument. But you have to read (or listen to) the entire thing – it is long and below are a few short snippets:

Does Tryptophan from turkey meat make you sleepy?

Posted on November 26, 2008 by Bora Zivkovic | 1 comment

It’s Thanksgiving tomorrow and the question (of the title of this post) pops up on the internets again. See SciCurious and Janet for the latest local offerings.
Short answer: we don’t know.
But there is endless speculation about it, each taking into account bits and pieces of information that we know about tryptophan and related physiology. The hypotheses tend to focus on:
a) Tryptophan itself, i.e., how it can get from food, through the intestine, through the bloodstream, to the brain and what it would do once there.
b) Serotonin, as a product of tryptophan metabolism, and how it can be produced (and where – in the brain or somewhere else) and what it would do once there.
I like to post and re-post, around this time of year, the third alternative, taking into account that serotonin is precursor of melatonin, that all the enzymatic machinery needed for transformation of tryptophan to melatonin operates in the intestine itself, that melatonin (unlike tryptophan) easily crosses the blood-brain barrier, and that melatonin does have some effect on sleepiness.
The posts (see the 2005, 2006 and 2007 versions) tend to elicit a lot of comments.
I am not claiming that this hypothesis is correct, just that it co-exists with other hypotheses that are just as untested as this one. Read it under the fold:

National Day of Listening

Posted on November 26, 2008 by Bora Zivkovic | Comments Off

StoryCorps is declaring November 28, 2008 the first annual National Day of Listening:

This holiday season, ask the people around you about their lives — it could be your grandmother, a teacher, or someone from the neighborhood. By listening to their stories, you will be telling them that they matter and they won’t ever be forgotten. It may be the most meaningful time you spend this year.

If you share something, is it useful and educational?

Posted on November 26, 2008 by Bora Zivkovic | 1 comment

Hmmm, juxtaposing these three posts is thought-provoking….what is education all about? Is the ‘coolness’ factor overpowering the ‘usefulness’ factor? Thoughts?
Planning to Share versus Just Sharing:

But inevitably, with a very few exceptions, these projects spend an enormous amount of time defining what is to be shared, figuring out how to share it, setting up the mechanisms to share it, and then…not really sharing much. Or sharing once but costing so much time, effort or money that they do not get sustained. Does this sound familiar to anyone else? I don’t feel like this phenomenon is isolated to me or somehow occurs because of my own personal ineptitude, but you never know.

Kewel:

It seems that neither Tony Hirst, the person who set this operation into motion, nor any of those who are blithely praising his work, bothered to think about the data itself or what it meant. That, indeed, as Hirst himself has repeatedly stated in response to my comments, “wasn’t the point.” But if someone can advocate, and others can gasp at, such mangling of data without even thinking about what happens to that data in the process, believing it to be somehow beside the point… well, that’s a textbook case of data illiteracy as far as I’m concerned.

Am I missing the point on open educational resources?:

In the early brainstorming discussions, I staked out something of a confrontational stance… that higher education is still conducting its business as if information is scarce when we now live in an era of unprecedented information abundance. That we in the institutions can endlessly discuss what content we deign to share via our clunky platforms, while Google, Wikipedia, YouTube, TED Talks, the blogs and other networked media just get on with it… That I might not be able to legally reproduce much of the copyrighted media on the web, but I can link to it, maybe embed it, or simply tell students to search for it. This is not to suggest that sharing more of the presumably high quality content that higher education produces would not enrich the store of available information… but that the world is not waiting for us to get our act together and become a relevant force on the web. The world is moving on without us.
One of the other participants asked a question that resonated with me: if we live in an era of information abundance, why is the primary drive around OERs the publication of more content? And what other activities around the open education movement might be an effective use of our energies? What other needs have to be met?

Then read this: The Digital Youth Project – Kids Need Time to ‘Hang Out,’ ‘Mess Around’ and ‘Geek Out’:

The report notes the similarities between community norms and what educators might call “learning goals” but it clearly denotes a new position for the adult who serves as an educator. Simply stated, schools are not known for allowing “plenty of unstructured time for kids to tinker and explore without being dominated by direct instruction.”
Instead of classroom teachers, there would be lab teachers or leaders who would have a different responsibility, one that does not focus on assessing kids’ for competence. Instead, these adults would be “co-conspirators” practicing a “pedagogy of collegiality.”

‘Academeology’ review in Nature

Posted on November 26, 2008 by Bora Zivkovic | 2 comments

Peggy Kolm wrote a book review in Nature of Academeology by Female Science Professor.
My copy arrived some weeks ago, but it will have to wait until I read at least three other books I promised to review….eh. Anyway, Peggy says:

FSP’s stories of being a woman in a male-dominated field are engrossing. She describes the casual sexism, such as being ignored or treated as a secretary by visiting scientists, or having male colleagues comment that she received an award “because she is a woman”. These tales might be disheartening to some. But FSP also relates her successes as a scientist and in navigating difficulties as one half of a scientist couple who began her academic career with a young child. Never claiming that her experiences are universal or that her path has been easy, FSP shows that it is possible to have both a career as a scientist and a life outside of science.

New and Exciting in PLoS ONE

Posted on November 25, 2008 by Bora Zivkovic | 1 comment

There are 11 new articles in PLoS ONE today. As always, you should rate the articles, post notes and comments and send trackbacks when you blog about the papers. You can now also easily place articles on various social services (CiteULike, Connotea, Stumbleupon, Facebook and Digg) with just one click.
Here is my pick for the week – you go and look for your own favourites…and in the meantime try your hand at making the funniest LOLCat to go with this article:
Whole Body Mechanics of Stealthy Walking in Cats:

The metabolic cost associated with locomotion represents a significant part of an animal’s metabolic energy budget. Therefore understanding the ways in which animals manage the energy required for locomotion by controlling muscular effort is critical to understanding limb design and the evolution of locomotor behavior. The assumption that energetic economy is the most important target of natural selection underlies many analyses of steady animal locomotion, leading to the prediction that animals will choose gaits and postures that maximize energetic efficiency. Many quadrupedal animals, particularly those that specialize in long distance steady locomotion, do in fact reduce the muscular contribution required for walking by adopting pendulum-like center of mass movements that facilitate exchange between kinetic energy (KE) and potential energy (PE) [1]-[4]. However, animals that are not specialized for long distance steady locomotion may face a more complex set of requirements, some of which may conflict with the efficient exchange of mechanical energy. For example, the “stealthy” walking style of cats may demand slow movements performed with the center of mass close to the ground. Force plate and video data show that domestic cats (Felis catus, Linnaeus, 1758) have lower mechanical energy recovery than mammals specialized for distance. A strong negative correlation was found between mechanical energy recovery and diagonality in the footfalls and there was also a negative correlation between limb compression and diagonality of footfalls such that more crouched postures tended to have greater diagonality. These data show a previously unrecognized mechanical relationship in which crouched postures are associated with changes in footfall pattern which are in turn related to reduced mechanical energy recovery. Low energy recovery was not associated with decreased vertical oscillations of the center of mass as theoretically predicted, but rather with posture and footfall pattern on the phase relationship between potential and kinetic energy. An important implication of these results is the possibility of a tradeoff between stealthy walking and economy of locomotion. This potential tradeoff highlights the complex and conflicting pressures that may govern the locomotor choices that animals make.
