Moake whose research group was the first to describe how high shear stress could cause platelets to stick to VWF said I had thought that the condition might last for such a short time that it would be unmeasurable.
However previous research had shown that a type of physical stress called shear --which can arise in partially occluded arterial blood vessels with high flow rates--could cause PVWF to become sticky to platelets.
Moake's and Dong's groups prepared samples of PVWF subjecting some to the shear stresses known to induce clot formation.

of stress on six continents. Examining the data from each paper and contacting original authors when necessary He determined the overall trends across the many experiments.
Our results show that plant interactions generally change with increased environmental stress and always in the direction of an outright shift to facilitation (typical for survival responses) or a reduction in competition (typical from growth responses) the authors wrote in the paper published online.
We never observed an increase in competition at higher stress. These findings were consistent across fitness measures stress types growth forms life histories origins climatic zones ecosystems and methodologies.
or neutral effects at high stress whereas less competitive species e g. trees have strong facilitative effects at high stress the authors wrote.
Overall the researchers found studies with observations of greater degrees of stress increase--longer stress gradients--also observed greater degrees of shift toward positive interactions.
They could only persist in groups suggesting that with stress organisms were better off together--despite their competition--than apart.
Bertness published the Stress Gradient Hypothesis in Trends in Ecological Evolution with Ray Callaway then a graduate student at the University of California-Santa barbara. Callaway is now a professor at the University of Montana.

It shows that increases in howler monkey'travel time'--the amount of time needed to find requisite nourishment--are leading to increases in levels of stress hormones called glucocorticoids.
This leads to the increased'travel time'and consequent high levels of stress we are seeing in these primates as their habitats disintegrate.
As trying to catch the howlers to examine them would in itself be highly stressful for the animal the best way of evaluating stress levels in wild primates is by analysing their faeces for glucocorticoid stress hormones which are general to all vertebrates.
Through statistical modelling the researchers were able to determine that it is the'travel time'--rather than the increased foliage intake--causing high levels of stress.
Monkeys in disturbed habitats suffering high levels of stress is in itself unsurprising perhaps but now we think we know why the root cause from the primates perspective.
The authors say that further studies are required to fully understand the significance of increases in stress in howler monkeys living in disturbed habitats.
Determining the full relevance of our results for the conservation of primates living in forest fragments will require long-term studies of stress hormones
