Temperature as a modulator of sexual selection
Published: 2018-12-03
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
A central question in ecology and evolution is to understand why sexual selection varies so much in strength across taxa, and it has long been known that ecological factors are crucial to this respect. Temperature is a particularly critical abiotic ecological factor that can drastically modulate a wide range of physiological, morphological and behavioural traits, impacting individuals and [...]
Subspecies status and methods explain strength of response to local versus foreign song by oscine birds in meta-analysis

Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
To understand the implications of geographical variation in vocal culture in songbirds, researchers have often compared territorial responses to playback of local songs versus responses to playback of songs from ‘foreign’ conspecifics. This body of work has the potential to help us move towards a general understanding of factors driving divergence in signal recognition. We conducted a systematic [...]

Females of a widespread species of the rock‐dwelling haplochromine cichlids of Lake Malawi, Maylandia zebra, show preference for males that successfully evict intruding males from their territory. This behaviour, experimentally induced by the investigators in a laboratory setting, was also preferred over males that were not permitted to interact with any other individual.
