Social conflict is defined operationally as occurring when the behavior of two (or more)
individuals indicates that their motivational priorities are incompatible: they seek the same …

Game theory in biology gained prominence 50 years ago, when Maynard Smith & Price
formulated the concept of an evolutionarily stable strategy (ESS). Their aim was to explain …

1. The relationship between maximal acceleration capacity and flight morphology was tested
experimentally in the butterfly Pararge aegeria. Such relations are often assumed but …

Discrete variation where one sex has more than one means of achieving the same
functional end, such as mating or nesting (alternative strategies and tactics), requires an …

In spatial studies of populations, Euclidean distance is commonly used to measure the
structural connectivity between habitat patches. The role of the matrix on patch connectivity …

The mating system maintained in a species has a strong effect on the degree of sperm
competition, and certainty of paternity should accordingly influence the optimal sperm …

Evolutionary studies typically focus on adaptations to particular environmental conditions,
thereby often ignoring the role of possible constraints. Here we focus on the case of variation …

Male butterflies display a diversity of mate-location tactics. This article describes the
observed diversity in encounter-site locations and in the behavior of males at encounter …

A common situation when animals compete for resources is that there is an owner-intruder
asymmetry. Many studies show that owners win most of these conflicts. We investigate how …

The males of many butterfly species compete via pair-wise intrasexual contests, yet lack any
obvious morphological traits conventionally associated with animal aggression. The …
