Corrigendum to “How do biases in sex ratio and disease characteristics affect the spread of sexually transmitted infections?” [J. Theor. Biol. 527 (2021) 110832]

The authors regret that there were errors in equations (12)–(15) on page 3 for the endemic equilibrium. Equations (12)–(15) should be replaced by [Formula presented] [Formula presented] [Formula presented] [Formula...

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...
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...

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...

Parental care and the evolution of terrestriality in frogs

Frogs and toads (Anura) exhibit some of the most diverse parental strategies in vertebrates. Identifying the evolutionary origins of parenting is fundamental to understanding the relationships between sexual selection, social...

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...

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...

The genetic sex-determination system predicts adult sex ratios in tetrapods

The adult sex ratio (ASR) has critical effects on behaviour, ecology and population dynamics, but the causes of variation in ASRs are unclear. Here we assess whether the type of genetic sex determination influences the ASR...

Does ecology and life history predict parental cooperation in birds? A comparative analysis

Abstract: In animals, species differ remarkably in parental care strategies. For instance, male-only care is prevalent in teleost fishes, while biparental care predominates in birds and female-only care is widespread in...

Males and females of a polygamous songbird respond differently to mating opportunities

Abstract: Parents are expected to make fine-tuned decisions by weighing the benefits of providing care to increase offspring survival against that of deserting to pursue future mating opportunities. A higher incentive for the...

The evolution of parental care in salamanders

Complex parenting has been proposed to contribute to the evolutionary success of vertebrates. However, the evolutionary routes to complex parenting and the role of parenting in vertebrate diversity are still contentious....

Environmental education in the classroom

To execute environmental education effectively, the success and impacts of educational activities must be assessed. In areas of high biodiversity there is generally a lack of evaluation of the impact of environmental...
