Cooperative Behaviors in Group-Living Spider Mites

open access: yesFrontiers in Ecology and Evolution, 2021
Cooperative behaviors are evolutionary stable if the direct and/or indirect fitness benefits exceed the costs of helping. Here we discuss cooperation and behaviors akin to cooperation in subsocial group-living species of two genera of herbivorous spider ...

Problem solving in European bison (Bison bonasus): two experimental approaches

open access: yesRoyal Society Open Science, 2021
The ability to solve novel problems is crucial for individual fitness. However, studies on problem solving are usually done on few taxa, with species with low encephalization quotient being rarely tested.

No evidence that relatedness or familiarity modulates male harm in Drosophila melanogaster flies from a wild population

open access: yesEcology and Evolution, 2022
Sexual selection frequently promotes the evolution of aggressive behaviors that help males compete against their rivals, but which may harm females and hamper their fitness.

Mountain gorillas maintain strong affiliative biases for maternal siblings despite high male reproductive skew and extensive exposure to paternal kin

open access: yeseLife, 2022
Evolutionary theories predict that sibling relationships will reflect a complex balance of cooperative and competitive dynamics. In most mammals, dispersal and death patterns mean that sibling relationships occur in a relatively narrow window during ...
