The concurrent divergence of mating traits and preferences is necessary for the evolution reproductive isolation via sexual selection, such coevolution has been demonstrated in diverse lineages. However, extent to which assortative mate are sufficient drive nature less clear. Natural contact zones between lineages divergent provide exceptional opportunities testing predicted evolutionary consequences divergence. strawberry poison frog (Oophaga pumilio) displays extreme color polymorphism...
Codivergence of mating traits and mate preferences can lead to behavioral isolation among lineages in early stages speciation. However, limit gene flow only when expressed as choice, numerous factors might be more important than nature. In the extremely color polytypic strawberry poison frog (Oophaga pumilio), female have codiverged with most allopatric populations tested. Whether these lab-assayed predict (gene flow) wild remains unclear. We observed courting pairs a natural contact zone...
Abstract Phenotypic polymorphism is common in animals, and the maintenance of multiple phenotypes a population requires forces that act against homogenizing drift selection. Male–male competition can contribute to stability when males compete primarily with same phenotype. In around contact zone between red blue lineages poison frog Oophaga pumilio , we used simulated territorial intrusions test nonexclusive predictions would direct more aggression towards (i) their own phenotype and/or (ii)...
Abstract Skin coloration and patterning play a key role in animal survival reproduction. As result, color phenotypes have generated intense research interest. In aposematic species, can be important avoiding predation mate choice. However, we still know little about the underlying genetic mechanisms of production, particularly outside few model organisms. Here seek to understand production different colors how these undergo shifting expression patterns throughout development. To answer this,...
Predator-prey interactions often vary on the basis of traits individual predators and prey involved. Here we examine whether multidimensional behavioral diversity predator groups shapes mortality rates selection behavior. We ran sea stars (Pisaster ochraceus) through three assays to characterize individuals' phenotype along axes. then created that varied in volume space they occupied. further manipulated ability interact with one another physically via addition barriers. Prey snails...
Abstract Sexual harassment is a widespread evolutionary outcome of sexual conflict over mating rates. Male can impose costs on females, and females often change their behaviors to avoid unwanted attention. In Trinidadian guppies (Poecilia reticulata), males use either sneak behavior or courtship displays as reproductive tactics. Both be sources harassment, but likely more harmful. Males adapted low-predation habitats fewer tactics than high-predation ancestors. Here, we tested whether female...
Abstract Codivergence of sexual traits and mate preferences can lead to assortative mating subsequently reproductive isolation. However, choice rarely operates without intrasexual competition, the effects latter on speciation are often overlooked. Maintaining trait polymorphisms despite gene flow limiting female for less-competitive male phenotypes two important roles that male–male competition may play in process. Both rely assumption limits expression divergent preferences. We tested this...
Evolutionary biologists have long been interested in parsing out the roles of genetics, plasticity and their interaction on adaptive trait divergence. Since males females often different ecological reproductive roles, separating how traits are shaped by interactions between genes environment is necessary important. Here, we disentangle sex-specific effects genetic divergence, developmental plasticity, social learning contextual foraging behaviour Trinidadian guppies ( Poecilia reticulata )...
Abstract Behavioural plasticity is a major driver in the early stages of adaptation, but its effects mediating evolution remain elusive because behavioural itself can evolve. In this study, we investigated how male Trinidadian guppies ( Poecilia reticulata ) adapted to different predation regimes diverged their mating tactic. We reared F2 juveniles high‐ or low‐predation population origins with combinations social and predator cues assayed behaviour upon sexual maturity. High‐predation males...
Abstract Male–male competition shapes resource distributions and reproductive success among individuals, can drive trait evolution when phenotypes differ in competitive abilities and/or strategies. Divergence of populations, regardless the cause, is often accompanied by divergence male ability, such asymmetries play an important role mediating interactions evolutionary trajectory nascent lineages. Here, we designed a field experiment to examine importance color, divergent trait, determining...
Individual recognition and winner/loser effects both play important roles in animal contests, but how their influences are integrated to affect an individual's contest decisions combination remains unclear. provides with relatively precise information about its ability defeat conspecifics that it has fought previously. Winner/loser effects, conversely, rely on sampling animal's win compares those of others the population. The less causing should therefore be more useful individual facing...
Abstract Phenotypic plasticity is critical for organismal performance and can evolve in response to natural selection. Brain morphology often developmentally plastic, affecting animal a variety of contexts. However, the degree which brain evolves has rarely been explored. Here, we use Trinidadian guppies (Poecilia reticulata), are known their repeated adaptation high-predation (HP) low-predation (LP) environments, examine evolution morphology. We exposed second-generation offspring...
Abstract The aposematic strawberry poison frog, Oophaga pumilio , is an iconic model system for studying the evolution and maintenance of color variation. Through most its range, this frog red with blue limbs. However, frogs from Bocas del Toro Province, Panama, show striking variance in pattern, both sympatrically allopatrically. This observation contradicts standard models aposematism has led to substantial speculation about evolutionary molecular causes. Since enigma O. phenotypic...
If you have ever been to a pet store and stopped at the aquariums, most likely seen guppy. Guppies come in diverse shapes sizes. Some large, beautiful fins, while others bright-colored bodies. It turns out that guppies are not only popular with owners. Scientists find be fascinating because these fish perfect for studying how species rapidly adapt new environments. Next time stop store, sure admire small but interesting fish.
