How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
Full-text available
Male mate choice occurs in several animal species, but we know little about the factors that influence the expression of this behaviour. Males vary in their capacity to acquire mates (i.e. male quality), which could be crucial to male mate choice expression but it is often overlooked. Using a meta‐analytical approach, we explore interindividual var...
Article
In the field of sexual selection, it is common to encounter the idea of ‘sex roles’: choosy and caring females and competitive and promiscuous males. Despite criticism of these stereotypes from some evolutionary biologists, sex roles still appear as a norm in much of the sexual selection-related literature. This may be because scientists anthropomo...
Article
Behaviours that are consistent across contexts (also known as behavioural syndromes) can have evolutionary implications, but their role in scenarios where the sexes conflict, such as sexual cannibalism, is poorly understood. While some research has focused on aggressive personality in females and its role in determining cannibalistic attack, effect...

Behaviours that are consistent across contexts (also known as behavioural syndromes) can have evolutionary implications, but their role in scenarios where the sexes conflict, such as sexual cannibalism, is poorly understood. The aggressive spillover hypothesis proposes that cannibalistic attacks during adulthood may depend on female aggressiveness...
Preprint
The traditional theory of sexual selection posits the idea of sex roles: females should be choosy and caring, while males should be competitive and promiscuous. Despite criticism of these stereotypes from some evolutionary biologists, sex roles still appear as a norm in the literature. This may be because scientists anthropomorphize animal behaviou...
Article
Females not only produce costly gametes, but also store the eggs until laying them, a period called gravidity. The volume that eggs occupy in the female abdomen may decrease female foraging ability by making them slower. Although females of all species are subjected to these potential costs, it remains an unexplored matter in invertebrates. Females...
Article
Male preference for high-quality females is expected to evolve when male reproductive potential is restricted. However, when there is competition among males, some models predict the evolution of assortative male mate choice, in which good competitors choose high-quality females while poor competitors choose lower quality females to avoid competiti...

Females not only produce costly gametes, but also store the eggs until oviposition, a period called pregnancy. The volume that eggs occupy in the female abdomen may decrease female foraging ability by making females slow.

Article
Male, female, pupa, larva and egg of a new genus and species of Gracillariidae (Ornixolinae), Cactivalva nebularia Moreira & Vargas gen. et sp. nov., from southern Brazil are described and illustrated with the aid of optical and scanning electron microscopy. A preliminary analysis of mitochondrial DNA sequences including members of related lineages...

Full-text available
Eugnosta Hübner, 1995 (Lepidoptera, Tortricidae, Tortricinae, Cochylini) is reported for the first time in Chile. Male and female adults, the pupa and the last-instar larva, and galls of Eugnosta azapaensis Vargas & Moreira sp. n. are described and illustrated from the Azapa Valley, northern Atacama Desert. The larvae induce fusiform galls on shoot...
Article
The study of immature stages is important in phylogeny, as well to the recognition and control of pest species.Glyphe-pomis Berg is included in the tribe Carpocorini.This paper describes the morphology of eggs and nymphs of Glyphepomis spinosa Campos & Grazia.Adult specimens were collected on rice plants in Formoso do Araguaia, Tocantins, Brazil, a...

Project
This is part of a MSc project on male-mate choice. We will use a meta-regression to understand general patterns of male mate choice.
