Later leaf emergence, earlier leaf loss: A new study of Ludwig-Maximilians-Universitaet (LMU) in Munich shows that the average vegetation periods of trees and shrubs in North America are intrinsically three weeks shorter than those of comparable species in Europe and Asia.
Especially male poison frogs piggyback their offspring to pools in the rainforest. Now, researchers from Vetmeduni Vienna, the University of Vienna and Harvard University showed that this parental behavior can be triggered experimentally. With unrelated tadpoles placed on their backs, male -- and even female -- 'foster parents' behave as if they had picked up the tadpoles themselves. This showed for the first time that an external stimulus triggers complex behaviors in amphibians. Journal of Experimental Biology.
Scientists at ITbM, Nagoya University have synthesized a new bioactive small molecule that has the ability to increase stomata numbers on flowering plants without stunting their growth. The team's new discovery could help elucidate the stomatal development mechanism in plants.
Associate Professor Kensuke Kawade at Okazaki Institute for Integrative Bioscience and National Institute for Basic Biology, in collaboration with Professor Hirokazu Tsukaya at the Graduate School of Science, the University of Tokyo, discovered that endoreduplication, which promotes cellular enlargement in the epidermal tissue of Arabidopsis thaliana, occurs randomly as a Poisson process throughout cellular maturation.
The nearly nine hundred giant stone statues discovered by the first Europeans to land on Easter Island seemed at odds with the small population found living there. It is believed a once thriving community witnessed sweeping ecological change and suffered internal conflict, resulting in a population crash. A new detailed study of the farming potential of the Island suggests it could have sustained 17,500 people at its peak.
Why are there so many more species in the tropics? The 'storage effect' is stronger there than in temperate forests.
A 5-year study that evaluated diet and lifestyle data from more than 373,000 individuals from 10 European countries between the ages of 25 and 70 says consuming nuts can reduce weight gain.
In a new study, scientists report significant strides in transferring disease- and stress-resistance traits from wild relatives of several legumes to their domesticated varieties.
new study of the world's seven sea turtle species provides evidence that their numbers are growing overall (unlike many endangered vertebrates), thanks to years of conservation efforts that have played a key role in sea turtle recovery -- even for small sea turtle populations.
A new Biological Reviews study provides a comprehensive assessment of how changes to wetlands affect animals, and the authors use their findings to provide recommendations for managing wetlands to maximise their biodiversity.
