An individual's phenotype can be altered by direct contact with its present environment but also by environmental features experienced by previous gen......
Introgression, the exchange of alleles between species, is a common event in nature. This transfer of alleles between species must happen through fert......
Mate choice for genetic benefits remains controversial, largely because few studies have estimated the relative contributions of additive and non-addi......
Ecology and biomechanics play central roles in the generation of phenotypic diversity. When unrelated taxa invade a similar ecological niche, biomecha......
Understanding of the causes by which reproductive isolation arises remains limited. We examine the role of adaptation in driving reproductive isolatio......
The rachises of extant feathers, composed of dense cortex and spongy internal medulla, are flexible and light, yet stiff enough to withstand the load ......
Species can evolve diverse strategies to survive periods of uncertainty. Animals may either invest in energy storage, allowing them to decrease foragi......
Dispersal syndromes are often defined by reference to fruit traits that are associated with distinct frugivore guilds. Studies rarely examine the rela......
Understanding the mechanisms of adaptive population differentiation requires that both the functional and adaptive significance of divergent traits ar......
Understanding the ecological and evolutionary mechanisms that shape a species' range is an important goal in evolutionary biology. Evidence indicates ......
Speciation is the process that generates biodiversity, but recent empirical findings show that it can also fail, leading to the collapse of two incipi......
Sequential polyandry may evolve as an insurance mechanism to reduce the risk of females choosing mates who are genetically inferior (intrinsic male qu......
The evolution of sperm quality and quantity is shaped by various selective processes, with sperm competition generally considered the primary selectiv......
Flower color polymorphism is relatively uncommon in natural flowering plants, suggesting that maintenance of different color morphs within populations......
