Climate and parasite pressure jointly shape traits mediating the coevolution between an ant social parasite and its host
Abstract. Host–parasite relationships are often shaped by coevolutionary arms races. While abiotic influences on these dynamics are well documented, a comb

Some pheromones are costly. Female moths use long distance pheromones to attract mates, with different blends of chemicals to indicate their species. #Moths producing higher amounts of acetates took longer to reach adulthood and produced fewer eggs per day:

Sea #otters have undergone distinctive evolutionary changes in the offspring size–number trade-off within the #Mustelidae. The changes involve larger and fewer offspring and more investment in offspring size than expected:

Why do single-celled organisms commit suicide?

Our latest research reveals that it is not a mystery, but a form of cooperation. Programmed cell death (PCD) can strengthen endosymbiosis between host and symbiont, thereby helping clones:
