Human behaviour
The ratio of males to females in a population is known to influence the behaviour, life histories and demography of animals. A recent experimental study finds that sex ratio also affects human economic behaviour, and in a manner...

Reputation effects in the market of certifiers
Áron Tóth
Apr 01, 2014
Certifiers verify unobserved product characteristics for buyers and thereby alleviate informational asymmetries and facilitate trade. When sellers pay for the certification, however, certifiers can be tempted to bias their...

The great industry gamble

Industry dynamics are studied as an endogenous tournament with infinite horizon and stochastic entry. In each period, firms' investments determine their probability of surviving into the next period. This generates a survival...

The impact of introduced predators on an island endemic, the St Helena Plover, Charadrius sanctaehelenae
We investigated the impact of introduced predators on the productivity of the St Helena Plover Charadrius sanctaehelenae, a shorebird endemic to the South Atlantic island of St Helena. The nest predator species identified have...

Social organization in ungulates

Ungulates (antelopes, deer and relatives) have some of the most diverse social systems among mammals. To understand the evolution of ungulate social organization, Jarman (1974) proposed an ecological scenario of how...

Divorce and infidelity are associated with skewed adult sex ratios in birds
Adult sex ratio (ASR) is a fundamental concept in population demography, and recent theory suggests that ASR plays a central role in social behavior, mating systems, and parental care [1-6]. Unbalanced ASRs are predicted to...

The evolution of sex roles in birds is related to adult sex ratio
Sex-role reversal represents a formidable challenge for evolutionary biologists, since it is not clear which ecological, life-history or social factors facilitated conventional sex roles (female care and male-male competition...

Sexual conflict and consistency of offspring desertion in Eurasian penduline tit Remiz pendulinus
Background: The trade-off between current and future parental investment is often different between males and females. This difference may lead to sexual conflict between parents over care provisioning in animals that breed with...

Experimental assessment of mating opportunities in three shorebird species
Mating opportunities may differ between closely related species, although the evidence for such variation is scant. Here we compare remating opportunities and courtship behaviour between three shorebird species: the Kentish...

Ontogenic differences in sexual size dimorphism across four plover populations

Sexual size dimorphism (SSD) among adults is commonly observed in animals and is considered to be adaptive. However, the ontogenic emergence of SSD, i.e. the timing of divergence in body size between males and females, has...

Global pattern of nest predation is disrupted by climate change in shorebirds

Ongoing climate change is thought to disrupt trophic relationships, with consequences for complex interspecific interactions, yet the effects of climate change on species interactions are poorly understood, and such effects...
