By recording grouper grunts for 12 years, scientists discovered major shifts in how red hind spawn and compete. Courtship calls once dominated, but territorial sounds have surged, suggesting changes in population structure. Machine learning helped decode the patterns quickly, offering a groundbreaking way to monitor and conserve reef fish.
Read moreMonkeys and other animals communicate through calls that can differ depending on region. The common marmoset is one such animal that communicates using regional dialects. Researchers have now found out that they even adapt their dialect when they move to a different area.
Read moreFish that are able to survive and adjust to warming waters may pass heat-tolerant genes not just onto their children, but their grandchildren too.
Read moreMale mice raised in space using specially developed cages were returned safely to Earth. The sperm production/fertilizing ability of the mice were normal and the reproduction ability of the offspring were not affected by their parents' stay in outer space. The findings on the effects of the environment in space on the male reproductive system will contribute to the accumulation of basic knowledge for humankind to expand the range of its activity to space.
Read moreNew research presents the first demonstration of a specific difference in sperm function associated with sex ratio skewing.
Read moreResearchers find genes that help maintain the 50-50 balance between male and female offspring in mice — and that have major implications for male infertility.
Read moreBiologists have described a new species of praying mantis that displays the first documented example of conspicuous mimicking of a wasp among praying mantises.
Read moreBecause of imprinted preferences, strawberry poison frog females mate more with similar colored males, and less with differently colored males. Over time, the behavior could lead to two color types becoming separate species.
Read moreRising night-time temperatures are causing woodland birds to build nests and lay eggs earlier in springtime, research shows.
Read moreNative to South America, imported fire ants have now spread to parts of North America and elsewhere around the world. These invasive pests have painful stings that, in some cases, can cause serious medical problems, such as hypersensitivity reactions, infections and even kidney failure. Now, researchers have identified pyridine alkaloids that, along with other venom components, could contribute to these conditions.
