Evolution of Altruism and Eusociality: Toward a Cost/Benefit Analysis of Fitness and Genetic Relatedness
Altruism is a behavior that benefits others at a cost to one’s own ability of survival and/or reproduction; that is, individual fitness. Thus, altruism poses great challenges to Darwin’s theory of evolution by natural ...
Effects of Gene Interactions on Polymorphism and Divergence
Patterns of interactions could influence the biological systems at various levels and potentially affect the evolutionary history. Gene interactions could affect the relation among genotypes and their phenotypes. Polymorphisms ...
Intraspecific variation in metacommunities: Linking regional heterogeneity to local population dynamics
Variation within species drives differences in population dynamics, interactions between species, and the functioning of complex ecosystems. Fittingly, understanding the factors that govern this intraspecific variation ...
Phenological shifts and species interactions: Disentangling the role of timing and synchrony
Most habitats exhibit seasonal changes in environmental conditions. These seasonal patterns can vary among years, which can alter the timing of the seasonal life-history events, or phenologies, of species (e.g., emergence ...
Carry-over effects in space: Beyond single species studies and towards metacommunity dynamics
The behavioral and physical traits of adults can be strongly influenced by conditions experienced during development. Consequently, variation in natal habitat quality across a landscape and through time can also lead to ...
