World's most venomous spiders are actually cousins
[unable to retrieve full-text content]Two lineages of dangerous arachnids found in Australia -- long classified as distantly related in the official taxonomy -- are, in fact, relatively close evolutionary cousins. The lineages include the most venomous spiders in the world. The findings could help in the development of novel antivenoms, as well as point to...

Hunting is changing forests, but not as expected
[unable to retrieve full-text content]In many tropical forests, over-hunting is diminishing the populations of animals who are vital for dispersing the seeds of woody plants. Those same plants are vital for carbon storage and previous theoretical modeling studies predicted dire consequences to defaunation, this research suggests otherwise. Instead the data shows the effects on the...

Hurricanes Irma and Maria temporarily altered choruses of land and sea animals
Audio recordings of Hurricanes Irma and Maria's passage over Puerto Rico document how the calls of coastal critters changed in response to the deadly storms. The hurricanes caused a major disruption in the acoustic activity of snapping shrimp, a reduction in insect and bird sounds, and potentially an intensification of fish choruses, according to new...
Australian fire beetle avoids the heat: Its infrared organs warn the insect of hot surfaces
The Australian fire beetle is attracted to freshly burnt wood. Experts also call this pyrophilia ("love of fire"). This behavior is not very common in insects. Merimna atrata however has a good reason for this. The dead wood provides plenty of food for the larvae of the beetle, so it uses the wood for oviposition.
But...
Study links fox domestication to gene activity in the pituitary gland
[unable to retrieve full-text content]A study of foxes offers new insights into the brain changes that occur in wild canids as they become more tame, researchers report. The study links fox domestication to changes in gene activity in the pituitary gland, a brain center that kicks out hormones to regulate various bodily functions, including the...
