Spiders, Webs and Insects: A New Perspective On Evolutionary History
Corals Can Sense What's Coming
Australian scientists have thrown new light on the mechanism behind the mass death of corals worldwide as Earth's climate warms. Coral bleaching, one of the most devastating events affecting coral reefs around the planet, is triggered by rising water temperatures. It occurs when the corals and their symbiotic algae become heat-stressed, and the algae which feed the corals either die or are expelled by the coral.
Do Not Harm Invasive Species That Pollinate, Study Warns
In an irony of nature, invasive species can become essential to the very ecosystems threatened by their presence, according to a recent discovery that could change how scientists and governments approach the restoration of natural spaces.
Princeton University researchers report this month in the journal Proceedings of the Royal Society B evidence that destructive, non-native animals that have been
New Projection Shows Global Food Demand Doubling by 2050
Global food demand could double by 2050, according to a new projection by David Tilman, Regents Professor of Ecology in the University of Minnesota's College of Biological Sciences, and colleagues, including Jason Hill, assistant professor in the College of Food, Agricultural and Natural Resource Sciences.
Producing that amount of food could significantly increase
Evolution of embryonic development in nematodes
Nematodes can be subdivided into basal Enoplea (clades 1 and 2) and more derived Chromadorea (clades 3 to 12). Embryogenesis of Caenorhabditis elegans (clade 9) has been analyzed in most detail. Their establishment of polarity and asymmetric cleavage requires the differential localization of PAR proteins. Earlier studies on selected other nematodes revealed
