Intraspecific agonistic interactions represent one of the most fundamental behaviors in studies of behavioral ecology, as they mediate individuals' access to resources essential for survival and/or reproduction. Understanding this type of interaction has led to the development of a series of theoretical models (based on evolutionary game theory) to try to explain why, in most species, riv…
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…

Podoctidae, the most diverse family in the superfamily Epedanoidea, is a Palaeotropical harvestmen group currently comprising 58 genera and 131 species. They exhibit high diversity in India, Sri Lanka, Southeast Asia, and the Philippines. Interestingly, the family contains the majority of endangered species within the order Opiliones, likely a consequence of high micro-endemism on small i…
Theoretical models and empirical evidence accumulated in recent years suggest that the evolution of paternal care in lineages such as fish, anurans and arthropods is more related to female choice than to offspring protection. Therefore, studying the interrelationship between paternal care and sexual selection is essential to understand why males of some species take care of their offsprin…
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 armaments are sexually selected traits widely distributed in nature. Given the costs associated with the production and maintenance of armaments, not all males can afford them. Therefore, when competition among males is intense, intrasexual dimorphism can evolve. Heavily armed males usually engage in fights to secure females or resources, while less armed males adopt alternative repr…
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…

Considering that parental care evolves to increase the survival of offspring, the question arises: which sex should be the responsible for this task? Several theoretical models have been proposed to explain the observed patterns of caregivers, including differences in gamete investment between sexes, modes of fertilization, uncertainty of the male paternity, and even female preferences. V…
This research aims to unravel the genetic underpinnings of phenotypic plasticity in the mite Rhizoglyphus echinopus, which exhibits two male morphs: fighters and scramblers. While fighter males possess modified legs for fighting, scramblers lack these traits. Using artificial selection techniques, the research explores the unobservable aspects of plastic traits, such as genetic thresholds…
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…
