Published: July 1, 2023

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental toxicants found in anthropogenic mixtures such as crude oil, air pollution, vehicle exhaust, and some natural combustion reactions. Single PAHs benzo[a]pyrene (BaP) also impact fish behavior when animals exposed early life stages for short periods of time. Aquatic may encounter BaP through road runoff oil spills, but few studies have examined the aqueous exposure on adult fish, fewer resulting fitness-relevant behavioral consequences PAH their long-term persistence. This dissertation targets this gap literature by examining how to influences anxiety-like behavior, learning, memory zebrafish, parental mixture, combined with hypoxia affects social exploratory unexposed larval zebrafish.

Lower habitats offer less refuge potentially leading predation pressure selecting greater by fish self-regulation.

This study evaluated the habitat coloration preferences of Siniperca chuatsi and Cirrhinus molitorella in both solitary (n = 1) group 3) settings across six colors. The results indicated that individual S. spent majority their time made frequent visits to black area, followed by blue area. While C. region, groups showed a preference for white regions. These findings highlight distinct different states, suggesting has an important effect on fish behavior environmental adaptation. From behavioral ecology perspective, these may be closely related survival strategies fish. Notably, molitorella's strong backgrounds reflect anti-predator behavior, helping avoid predators, such as chuatsi, natural environments, thereby improving its chances survival. provides scientific basis optimizing aquaculture emphasizing importance considering substrate type designing environments enhance welfare.

Abstract Cannibalism, the act of preying on and consuming a conspecific, is taxonomically widespread, putatively important in wild, particularly teleost fishes. Nonetheless, most studies cannibalism fishes have been performed laboratory. Here, we test four predictions for evolution by conducting one largest assessments wild to date coupled with mesocosm experiment. Focusing mosquitofishes guppies, examined 17 species (11,946 individuals) across 189 populations spanning both native invasive ranges including disparate types habitats. We found be quite rare wild: showed no evidence cannibalism, prevalence was typically less than 5% within when it occurred. Most victims were juveniles (94%; only half these appeared newborn offspring), remaining 6% being adult males. Females exhibited more males, but this partially explained their larger body size, suggesting greater energetic requirements reproduction likely play role as well. that dispersal‐limited environments had lower higher conspecific densities, intense resource competition drives cannibalistic behavior. Supporting conclusion, our experiment revealed increased density levels not associated juvenile or strongly influenced predation risk. suggest livebearing because conspecifics energetically costly becomes worth effort other food intense. Due artificially reduced cost capturing confined spaces, captive settings can much frequent.

Abstract Predation risk is often invoked to explain variation in stress responses. Yet, the answers several key questions remain elusive, including following: (1) how predation influences evolution of phenotypes, (2) relative importance environmental versus genetic factors reactivity and (3) sexual dimorphism physiology. To address these questions, we explored (ventilation frequency) a post‐Pleistocene radiation live‐bearing fish, where Bahamas mosquitofish ( Gambusia hubbsi ) inhabit isolated blue holes that differ risk. Individuals populations coexisting with predators exhibited similar, relatively low as compared low‐predation populations. We suggest this dampened has evolved reduce energy expenditure environments frequent intense stressors, such piscivorous fish. Importantly, magnitude responses by fish from high‐predation sites wild changed very little after two generations laboratory rearing absence predators. By comparison, greater among‐population larger changes subsequent rearing. These appear have more lower food availability. Moreover, females showed ventilation frequency, was stronger This may reflect premium placed on efficiency females, especially under show higher fecundities.

Abstract The astonishing diversity of brain sizes observed across the animal kingdom is typically explained in context trade‐offs: benefits a larger brain, such as enhanced cognitive ability, are balanced against potential costs, increased energetic demands. Several hypotheses have been formulated this framework, placing different emphasis on ecological, behavioural, or physiological aspects trade‐offs size evolution. Within body work, there exists considerable taxonomic bias towards studies birds and mammals, leaving some uncertainty about generality respective arguments. Here, we test three most prominent hypotheses, ‘expensive tissue’, ‘social brain’ ‘cognitive buffer’ large dataset fishes, derived from publicly available resource (FishBase). In accordance with predictions tissue’ hypothesis, brains co‐occur reduced fecundity sociality at least Classes fish. Contrary to expectations, however, lifespan large‐brained tendency for species that perform parental care smaller brains. As such, it appears costs (reduced fecundity) (increased sociality) near universal vertebrates, whereas others more lineage‐specific effects. We discuss our findings fundamental differences between classically studied mammals fishes analyse here, namely divergent patterns growth, parenting neurogenesis. work highlights need taxonomically diverse approach any question evolutionary biology.
