New large-sized insect species discovered in tropical forest
Scientists have studied the diversity of tropical parasitoid wasps for years. Parasitoid wasps are among the most species rich animal taxa on Earth, but their tropical diversity is still poorly known. Recently, the research group sampled Afrotropical rhyssine wasps, which are among the largest wasps.
Read moreHow bats relocate in response to tree loss
Identifying how groups of animals select where to live is important for understanding social dynamics and for management and conservation. In a recent study, researchers examined the movement of a maternity colony of big brown bats as a response to naturally occurring tree loss.

Isolation, extreme weather, and the possible arrival of humans may have killed off the holocene herbivores just 4,000 years ago.
Read moreBumble bee workers sleep less while caring for young
All animals, including insects, need their sleep. Or do they? That's the question researchers are exploring in sleep studies of a surprising group of subjects: brood-tending bumble bee workers. Their studies show that worker bees tending pupae sleep much less than other bees do, even when caring for offspring that aren't their own.
Read moreBesides hot water, coral bleaching also about location, location, location
A new study revealed a more complex view than current standard predictions of coral bleaching events caused primarily by heat stress; rather, the scientists found that bleaching is driven by a variety of stressors, and each region responds differently.
Read moreNew imaging platform examines mechanisms behind coral bleaching
A non-invasive approach could help marine biologists monitor coral health in the face of climate change.
Read moreWarming impedes a coral defense, but hungry fish enhance it
Corals exude chemical defenses against bacteria, but when heated in the lab, those defenses lost much potency against a pathogen common in coral bleaching. There's hope: A key coral's defense was heartier when that coral was taken from an area where fishing was banned and plenty of fish were left to eat away seaweed that was overgrowing corals elsewhere.

Understanding the causes and consequences of Late Quaternary megafaunal extinctions is increasingly important in a world of growing human populations and climate change. A review highlights the role that cutting-edge scientific methods can play in broadening the discussions about megafaunal extinction and enabling insights into ecosystems and species-specific responses to climate change and human activities.
Read moreFossil fish gives new insights into evolution after end-Cretaceous mass extinction
An international research team has discovered a new and well-preserved fossil stingray with an exceptional anatomy, which greatly differs from living species. The find provides new insights into the evolution of these animals and sheds light on the recovery of marine ecosystems after the mass extinction occurred 66 million years ago.
