Discrete but variable structure of animal societies leads to the false perception of a social continuum
(2016)
Animal societies are typically divided into those in which reproduction within a group is monopolized by a single female versus those in which it is shared among multiple females. It remains controversial, however, whether ...
Artificial light onwater attracts turtle hatchlings during their near shore transit
(2016)
We examined the effect of artificial light on the near shore trajectories of turtle hatchlings dispersing from natal beaches. Green turtle (Chelonia mydas) hatchlings were tagged with miniature acoustic transmitters and ...
Responsiveness to conspecific distress calls is influenced by day roost proximity in bats
(2016)
Distress calls signal extreme physical distress, e.g. being caught by a predator. In many bat species, distress calls attract conspecifics. Because bats often occupy perennial day-roosts, they might adapt their responsiveness ...
How far will a behaviourally flexible invasive bird go to innovate?
(2016)
Behavioural flexibility is considered a key factor in the ability to adapt to changing environments. A traditional way of characterizing behavioural flexibility is to determine whether individuals invent solutions to novel ...
Coexistence of three sympatric cormorants
(2016)
Resource partitioning is well known along food and habitat for reducing competition among sympatric species, yet a study on temporal partitioning as a viable basis for reducing resource competition is not empirically ...
Signalling with a cryptic trait
(2016)
Sexual signals often compromise camouflage because of their conspicuousness. Pigmentation patterns, on the contrary, aid in camouflage. It was hypothesized that a particular type of pattern—barred plumage in birds, whereby ...
High atmospheric temperatures and ‘ambient incubation’ drive embryonic development and lead to earlier hatching in a passerine bird
(The Royal Society, 2016)
Tropical and subtropical species typically experience relatively high atmospheric temperatures during reproduction, and are subject to climate-related challenges that are largely unexplored, relative to more extensive work ...
Attack risk for butterflies changes with eyespot number and size
(2016)
Butterfly eyespots are known to function in predator deflection and predator intimidation, but it is still unclear what factors cause eyespots to serve one function over the other. Both functions have been demonstrated in ...
Morphological adaptation of the calamistrum to the cribellate spinning process in Deinopoidae
(2016)
Spiders are famous for their silk with fascinating mechanical properties. However, some can further produce, process and handle nano fibres, which are used as capture threads. These ‘cribellate spiders’ bear a specialized ...
She more than he: gender bias supports the empathic nature of yawn contagion in Homo sapiens
(2016)
Psychological clinical and neurobiological findings endorse that empathic abilities are more developed in women than in men. Because there is growing evidence that yawn contagion is an empathy-based phenomenon, we expect ...
