Behavioral differences among groups can have profound impacts on individual fitness,1 yet how group-level phenotypes arise and change during developme…

We reared and recorded behaviours of clonal Amazon mollies in standardized environments, with and without predation stress, from birth through week four of life, to understand how the developmental e...

Animal behaviours shape ecological dynamics, from species distributions to ecosystem function. These dynamics emerge from the behaviours of multiple i…

Adaptive phenotypic plasticity is expected to evolve when environmental conditions change predictably over time. This has led to the hypothesis that ectotherms in environments with low temperature sea...

Anthropogenic disturbance can drive hybridization by altering pre-mating reproductive barriers. Moran et al. pair population genomic surveys with water chemistry and GIS data to show that human develo...

Animal communication behaviors are complex, dynamic, conspicuous, and often critically important for individual fitness as well as sociality. For these reasons, animal communication has been of intere...

Synopsis. The word sex can refer to at least seven distinct, evolutionarily related biological phenomena (0–6 below). Bacteria and archaea use mechanisms f

1. Adaptive phenotypic plasticity can help organisms cope with global warming by increasing their heat tolerance, yet most research has focused on whole-organism traits. Much less is known about therm...

Insects employ a variety of conspicuous traits and courtship behaviors to mediate mate choice. Visual displays are especially common in tephritid flies with patterned wings, but it has long been debat...

To persist on our warming planet, arthropods will need to be able to survive and successfully reproduce under the new temperature conditions. However,…

Zoologiska institutionen är en av de äldsta institutionerna vid Stockholms universitet och har en lång historia av grundläggande och tillämpad djurforskning, från leddjur till stora däggdjur. I

Abstract. The evolution of novel animal signals is critical to the generation of biodiversity. Here, we explore how new sexual signals become established.

Communications Biology - Discovery of chemosensory sensilla with different distributions on the body appendages and between the sexes of a cursorial spider, combined with evidence of olfactory mate...

We show that hotter juvenile temperatures can increase adult fertility in an emerging model insect system. These reproductive benefits may be crucial for insect populations to avoid extinction during....

Researchers speak out against proposal that would bar funding for U.S. scientists working with Chinese partners or training Chinese students

We show that hotter juvenile temperatures can increase adult fertility in an emerging model insect system. These reproductive benefits may be crucial for insect populations to avoid extinction during...

Synopsis. Sexual selection is often invoked to explain the evolution of extravagant morphologies, such as antlers and horns. While the focus is typically o

Invasive species cause major disturbances to endemic wildlife and often displace native species. Behavioral aggression can contribute to invasive spec…

Nature Climate Change - The authors use 1,603 estimates of local extinctions from 1980 to 2021 to show that dragonfly species with wing ornamentation have disproportionately gone extinct and lost...
