Harem holding males do not rise to the challenge
(2014)
The challenge hypothesis has been enormously successful in predictinginterspecific androgen profiles for vertebrate males. Nevertheless, in the absence of another theoretical framework, many researchers ‘retrofit’ the ...
Sex ratio effects on reproductive strategies in humans
(2015)
Characterizations of coy females and ardent males are rooted in models of sexual selection that are increasingly outdated. Evolutionary feedbacks can strongly influence the sex roles and subsequent patterns of sex ...
A spectacular new species of seadragon
(2015)
The exploration of Earth’s biodiversity is an exciting and ongoing endeavour. Here, we report a new species of seadragon from Western Australia with substantial morphological and genetic differences to the only two other ...
Initiation and spread of escape waves within animal groups
(2015)
The exceptional reactivity of animal collectives to predatory attacks is thought to be owing to rapid, but local, transfer of information between group members. These groups turn together in unison and produce escape waves. ...
A pheromone outweighs temperature in influencing migration of sea lamprey
(2015)
Organisms continuously acquire and process information from surrounding cues. While some cues complement one another in delivering more reliable information, others may provide conflicting information. How organisms extract ...
Pre-zygotic isolation in the macroalgal genusFucus from four contact zones spanning 100–10 000 years
(2015)
Hybrid zones provide an ideal natural experiment to study the selective forces driving evolution of reproductive barriers and speciation. If hybrid offspring are less fit than the parental species, pre-zygotic isolating ...
Experimental evidence for convergent evolution of maternal care heuristics in industrialized and small-scale populations
(2015)
Maternal care decision rules should evolve responsiveness to factors impinging on the fitness pay-offs of care. Because the caretaking environments common in industrialized and small-scale societies vary in predictable ...
Crypsis via leg clustering
(2015)
The role of background matching in camouflage has been extensively studied. However, contour modification has received far less attention, especially in twig-mimicking species. Here, we studied this deceptive strategy by ...
First report of Plesiochelys etalloniandTropidemys langiifrom the Late Jurassic of the UK and the palaeobiogeography of plesiochelyid turtles
(2016)
Plesiochelyidae is a clade of relatively large coastal marine turtles that inhabited the shallow epicontinental seas that covered western Europe during the Late Jurassic. Although the group has been reported from many ...
First evidence of hybridization between golden jackal (Canis aureus) and domestic dog (Canis familiaris) as revealed by genetic markers
(2015)
Interspecific hybridization is relatively frequent in nature and numerous cases of hybridization between wild canids and domestic dogs have been recorded. However, hybrids between golden jackals (Canis aureus) and other ...
