Concerns about biodiversity tend to focus on the loss of species, but a new study suggests that the loss of variation within species can also have important and unexpected consequences on the environment.
New paleontological research shows that during the late Permian, the equator was dry and desert-like, yet surprisingly a hotspot for biodiversity. Similarly to modern rainforests, equator ecosystems were home a unique diversity of species, including those both anciently and newly evolved. After the late Permian extinction, this diversity was decimated, and the climate change event that triggered an extinction back then is informative as we move forward with protecting our planet's species diversity.
Global climate warming is considered a major threat to many living organisms but not all consequences of warming need to be harmful to species. A recent study from the University of Helsinki published on Evolution shows that two bird species react differently to warmer spring temperatures, succeeding to mitigate negative effects of competition and mixed breeding.
Three billion years ago, the sun shone weaker, but Earth stayed surprisingly warm. Carl Sagan thought a greenhouse effect must have been to thank. A model built on 359 chemical processes has finally arrived at scenarios with a reasonable chance of producing the needed methane on ancient Earth. The model has broad parameters in hope that it may someday be of use to interpret conditions on exoplanets.
In a recent study published in Zoological Journal of the Linnean Society, a team of Brazilian researchers discovered six new species of silky anteater, a mammal that lives in tropical rain forests of the Amazon region and Central America.
Ecologists commonly round off the individuality of individuals, treating animals of the same species, sex, and age like identical units. But individual differences can have demographic effects on interpretation of data at the scale of whole populations, if due to an underlying variability in individual quality, not chance. Researchers examined in the peculiarities that make some wandering albatrosses more successful than others in a study published in the Ecological Society of America's journal Ecological Monographs.
A new study by a team of international experts, led by Dr James Neenan, a Postdoctoral Fellow at the Evolutionary Studies Institute at Wits University in South Africa, has revealed that a completely extinct group of marine reptiles called sauropterygians evolved similar inner ear proportions to those of some modern day aquatic reptiles and mammals.
A new study led by Oxford University Museum of Natural History has revealed that an extinct group of marine reptiles called sauropterygians evolved similar inner ear proportions to those of some modern day aquatic reptiles and mammals. The research is published in Current Biology today.
A 530-million-year-old fossil contains what could be the oldest eye ever discovered, a study reveals.
New research suggests an urgent need to find out why sea snakes are disappearing from known habitats, after it was discovered some seemingly identical sea snake populations are actually genetically distinct.
