- Interplay between paternal care and sexual selection in harvestmen, AP.R
Abstract
Understanding the causes of variation in mating success and other fitness-related measures is a fundamental goal of sexual selection studies. In species exhibiting exclusive male care, the expected quality of paternal behavior can influence female mating decisions and thus determine male mating success. In arthropods, for instance, female preference for parental individuals may have fav...

- Macroecology of sexual selection: large-scale influence of climate on sexually selected traits, AP.R
Abstract
The general aim of this project is to provide a theoretical framework to approach the study of sexual selection in a broad geographic scale using the Neotropics as a reference to compare what we know of sexual selection and reproductive strategies in this and other environments of the planet. First, we will postulate broad predictions concerning the effect of environmental factors on re...
- Implications of autotomy of metasoma for locomotion, reproduction, foraging, and defense in scorpions, BP.DR
Abstract
The mechanisms of defense exhibited by the prey are incredibly diverse and play two main roles: to decrease the chance of detection by the predator and to increase the chance of escaping an attack. Among the defensive mechanisms that increase the chance of escaping, one of the most studied is autotomy, which is the voluntary detachment of body parts to avoid predation. Although this beh...
- Behavioral precursors and the origin of parental care in arthropods, BP.PD
Abstract
The origin of parental care is a key subject in evolutionary biology. Theoretical models suggest that the origin of parental care is influenced by factors such as ecological conditions, parental and trans-generational effects, and behavioral precursors. Among these factors, ecological conditions and parental effects are the most intensively studied. Trans-generational effects are receiv...
- Computational models for the evolution of female choice and male sexual ornaments, BP.PD
Abstract
The two most influential models for the evolution of female mate choice and male sexual ornaments are those proposed by Fisher and Zahavi. Despite their importance for the theoretical development in the field of sexual selection, it remains doubtful if these models really generate contrasting predictions. In addition, both models include natural and sexual selection, so that there are n...
- Effects of the availability of reproductive sites on the intensity of sexual selection and costs of parental care, BP.MS
Abstract
A central concept in the mating system theory is the environmental potential for polygyny, which postulates that scarce and aggregates resources favor the monopolization of females by a few males. Breeding sites are one of the most important resources used by females and, in many species, these sites are monopolized by larger males or males in better condition. The objective of this pro...
- Function of multimodal displays and the effect of environmental factors on the reproductive success of a neotropical frog (Anura, Hylodidae), BP.PD
Abstract
Signals are basic blocks that constitute the communication, and the combination of the emission of signals and the responses to them comprise the communication process. The acoustic communication has a key role in the life history of anurans because it is used to mediate social interactions, influences the risk of predation and parasitism, and is directly linked to reproductive success....
- Evolution of condition dependent sexual dimorphism in a clade of neotropical arachnids: a comparative analysis of the genic capture hypothesis, BP.PD
Abstract
Although widely documented in nature, the mechanisms responsible for the evolution of sexual dimorphism are poorly understood. When genes encoding a sexually dimorphic trait are present in individuals of both sexes, the expression of this trait is subject to an intersexual genetic correlation that acts against the evolution of sexual dimorphism. The genic capture hypothesis provides a p...

- Using network analyses to explore the mechanisms underlying female choice of extra-pair mates, BE.EP.DR
Abstract
The classic Darwin-Bateman paradigm of sexual selection states that females gain no benefits by mating with multiple males, and so polyandry should be rare. Recent evidence, however, shows that polyandry is widespread across many animal groups, and that multiple matings by females generate additional episodes of sexual selection, which modulate the total strength of sexual selection. Ex...
