South Asian Cnemaspis are one of the most diverse clades of gekkonids in South Asia with
their highest diversity in the Western Ghats and Sri Lanka. These geckos include only a few …

Animal signal colors evolve to efficiently stimulate conspecific visual systems. The sensory
drive hypothesis proposes that species differences in habitat light conditions favor the …

Sexual selection has long been thought to increase species diversification. Sexually
selected traits, such as sexual signals that contribute to reproductive isolation, were thought …

Elaborate sexual signals are thought to have evolved and be maintained to serve as honest
indicators of signaller quality. One measure of quality is health, which can be affected by …

Chemical signals, such as those used in social communication, are often present as
complex blends of compounds, suggesting that complexity is important in signal perception …

The environment presents challenges to the transmission and detection of animal signalling
systems, resulting in selective pressures that can drive signal divergence amongst …

Urban areas comprise a matrix of natural and human-made microhabitats, with associated
variation in microclimates. Since reptiles are dependent on environmental temperature for …

Brain size can vary between populations in different environments because of different
selection pressures on behaviours, such as learning and memory, related to spatial, social …

Animal signals in multiple modalities expands the opportunity for effective communication.
Among diurnal geckos of the genus Cnemaspis, chemical signalling traits preceded the …

Population isolation and concomitant genetic divergence, resulting in strong
phylogeographical structure, is a core aspect of speciation initiation. If and how speciation …
