Anthropogenic changes to the landscape and climate cause novel ecological and evolutionary
pressures, leading to potentially dramatic changes in the distribution of biodiversity. …

Members of different species often engage in aggressive contests over resources. This series
of aggressive contests between species may result in an interspecific dominance hierarchy…

Colour polymorphisms play a key role in sexual selection and speciation, yet the mechanisms
that generate and maintain them are not fully understood. Here, we use genomic and …

Citizen science datasets are becoming increasingly important means by which researchers
can study ecological systems on geographic and temporal scales that would be otherwise …

Many factors may influence the evolution of acoustic signals, including sexual selection,
morphological constraints and environmental variation. These factors can play simultaneous …

Conservation science has rapidly adopted citizen science to engage the public in knowledge
generation, developing environmental policies, solving localized environmental issues, …

House Sparrow (Passer domesticus) populations declined across much of their global range
in the late 20th century. Most research examining this decline is conducted in the species' …

When individuals mate outside the pair bond, males should employ behaviours such as
aggression or vocal displays (eg duetting) that help assure paternity of the offspring they care for…

Sexual signals can be important mechanisms of reproductive isolation among incipient
species, but the relative effectiveness and geographic distribution of different signals may vary, …

Sexual selection on multiple signals may lead to differential rates of signal introgression across
hybrid zones if some signals contribute to reproductive isolation but others facilitate gene …
