Tracing the rapid evolution of spermatogenesis across mammals
Evolutionary pressure across male mammals to guarantee the procreation of their own offspring led to a rapid evolution of the testicle. Bioinformatic studies—conducted by an international team of researchers led by Prof. Dr. Henrik Kaessmann from t.....»»
Study reveals spatial and temporal evolution of precipitation in Indo-Pacific region over the last 40,000 years
The Indo-Pacific warm pool is the warmest ocean in the world and is known as "the global heat engine," which plays an important role in the climate system......»»
Twin brother spotted hyenas are often attracted to the same new group when they disperse from their birth group
In most mammals, males disperse to a new group after reaching sexual maturity. Dispersal often entails costs and is risky. New results from spotted hyenas show that males from the same birth group—and particularly twin brothers—very often dispers.....»»

Insects may feel pain, says growing evidence: Here"s what this means for animal welfare laws
At least a trillion insects are killed annually for food and animal feed. Routine slaughter methods include extreme heat and cold, often preceded by starvation. By comparison, "only" around 79 billion mammals and bird livestock are slaughtered every.....»»
Assessment of urban water-energy interactions and heat island signatures in Rhode Island
A study of the urban heat island effect that warms Rhode Island focused on the connections between water and energy use, which could lead to better understanding and mitigation of the effect there and in similar urban areas as the global climate warm.....»»
Growth of forests may have contributed to extinction of large mammals in Central Europe 11,000 years ago
Herds of megafauna, such as mammoth and bison, have roamed the prehistoric plains in what is today's Central Europe for several tens of thousands of years. As woodland expanded at the end of the last Ice Age, the numbers of these animals declined, an.....»»

Florida mints radiated as peninsula sank and resurfaced during ice ages, finds study
During the ice ages of the Pleistocene, the Florida peninsula regularly grew to twice its current size as glaciers expanded near the planet's poles, only to be reduced to a series of islands as melting ice returned to the sea during warm periods. All.....»»

Study indicates SARS-CoV-2 variants are still transmissible between species
Scientists believe bats first transmitted SARS-CoV-2 to humans in December 2019, and while the virus has since evolved into several variants such as delta and omicron, a new study indicates the virus is still highly transmissible between mammals. Res.....»»
Study: To save nature, focus on populations, not species
Human-released greenhouse gases are causing the world to warm, and with that warming comes increasing stress for many of the planet's plants and animals. That stress is so great that many scientists believe we are currently in the midst of the "sixth.....»»
Large terrestrial mammals are more vulnerable to acoustic impact of drones than to visual impact
