Evolution Is Predictable Shown by Lizards

University of California - Davis If you could hit the reset button on evolution and start over, would essentially the same species appear? Yes, according to a study of Caribbean lizards by researchers at the University of California, Davis, Harvard University and the University of Massachusetts. The work is published July 19 in the journal Science. The predictability of evolution over timescales of millions of years has long been debated by biologists, said Luke Mahler, a postdoctoral...

Image 1 - Dinosaurs May Have Doomed Their Species By Laying Eggs
2012-04-18 14:10:50

New research suggests that the way dinosaurs reproduced could have led to their demise. According to research from the Zoological Society of London, dinosaurs became at risk when they began to lay eggs. Working together with colleagues, Daryl Codron and Marcus Clauss from the University of Zurich conducted this research into the possible beginning stages of the dinosaurs extinction. Their work has been published in the journal Biology Letters. The trouble could have been the sheer size of...

Separate species that live in radically different environments don't necessarily also have different ecological niches. This is the finding of a study investigating the accuracy of current statistical tests that use models of geographic distributions to infer changes in environmental requirements. In a new study published in the journal Systematic Biology, a model simulating the distributions of two imaginary species with identical environmental requirements, or ecological niches, was...

Competition plays a decisive role in climate change adaptation Species distribution models are of only limited use in predicting the future distribution of mammals. This is the finding of a study of the climate niches of 140 indigenous European mammals. The researchers analyzed data on species distribution, climate, land cover and topography, as well as the phylogenetic information of the species. Judging by the large differences in climate niches even for closely related species, mammals...

Scientists at UC Santa Barbara have found strong evidence that niche differences are critical to biodiversity. Their findings are published online in this week's issue of the journal Nature."Ecologists have long assumed that species differences in how they use the environment are key to explaining the large number of species we see all around us, but the importance of such niches have never been field tested," said first author Jonathan M. Levine, associate professor in UCSB's Department of...

Consider the case of the three-spine stickleback. These tiny fish that thrive in oceans and in fresh water might appear to be the same, yet ecologists are finding that they are actually a diverse collection of very specialized individuals.Understanding the ecological causes and consequences of such ecological variation is the goal of a group of scientists meeting at the National Institute for Mathematical and Biological Synthesis (NIMBioS) at the University of Tennessee, Knoxville, July...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
