Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.
A study of the bacteria in the guts of three lemur species offers new insights into the role of diet in shaping these microbial ecosystems – and how these microbes may relate to primate health.
Scientists are disputing the possibility that a significant portion of the world's forests have been missed in an earlier accounting of ecological diversity.
Zooplankton are often considered to be a passive source of food for fish and other aquatic animals. But at least one of their representatives, the millimetre-sized copepod (Eurytemora affinis), moves purposefully in turbulent ...
No place on the planet is truly isolated anymore, which means invasive species travel as easy as humans, hitchhiking on boats and planes with potentially devastating effects on the ecosystems they land in.
Trees in California communities are working overtime. From removing carbon dioxide and pollutants from the air, intercepting rainfall and increasing property values, California's 173.2 million city trees provide ecosystem ...
Arctic and major fishing nations, including China, announced Friday that they have agreed to a moratorium on commercial fishing in Arctic waters before a fishery in the icy region is even feasible.
Antidepressants are making their way into our lakes and rivers—and they're making freshwater fish less fazed by predators.
Scientists in Antarctica have demonstrated a cheaper, faster and simpler way to gauge the condition of leopard seals, which can weigh more than a half ton and reflect the health of the Antarctic ecosystem that they and a ...
Higher plant species richness may not be enough to protect ecosystems from the worst impacts of climate extremes
Studies on mild fluctuations in weather have provided support for the idea that higher biodiversity results in more stable functioning of ecosystems, but critical appraisal of the evidence from extreme event studies is lacking.
