Effect of ambient noise on parent–offspring interactions in tree swallows
ML Leonard, AG Horn, KN Oswald, E McIntyre - Animal behaviour, 2015 - Elsevier
Highlights • We applied 65 dB (SPL) white noise to tree swallow nests. • More nestlings
begged, but parents were less responsive to playback of begging calls. • Despite such changes …

Seasonal physiological responses to heat in an alpine range-restricted bird: the Cape Rockjumper (Chaetops frenatus)
Hot, dry summer conditions impose physiological stress on endotherms, yet we have a poor
understanding of how endotherms seasonally adjust their costs of thermoregulation under …

Behaviour of an alpine range-restricted species is described by interactions between microsite use and temperature
Climate change predictions include increased mean temperatures and increased frequency
of heatwaves. Short-term responses to high air temperatures can allow animals to conserve …

Small-scale land-use change effects on breeding success in a desert-living social bird
Human villages in deserts can provide resources in an otherwise stark environment, potentially
buffering against extreme environmental conditions. It is thus expected that breeding …
