In many animal species, some males exhibit an alternative reproductive tactic that differs from conventional tactics. For example, if the majority of males defend reproductive territories, males who exhibit an alternative tactic can act as satellites or even mimic females to invade such territories. When more than one reproductive tactic is successfully employed by males in a population, …
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 favor…
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 repr…
In many animal species, some males exhibit an Alternative Reproductive Tactic (ART) that differs from conventional tactics. For example, if most males defend reproductive territories, males that exhibit ARTs can act as satellites or even mimic females to invade such territories. When more than one reproductive tactic is successfully employed by males in a population, disruptive selection …
Male mate choice occurs when sexual investment by males in either mating of parental effort is very high. Among gift giving species, it is expected that males would be choosy during mate selection because the gift is costly to produce. In this research, we tested whether males of the gift giving spider Paratrechalea ornata adjust their reproductive investment (i.e., gift size, courtship i…
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 behav…
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 receivin…

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. Extr…
