Biomonitoring involves the use of biological organisms to detect or measure presence various toxic substances rather on land in water. Fish resides aquatic environments and its position at top food chain has made it a useful tool for biomonitoring.

ABSTRACT Human activities have significantly altered coastal ecosystems worldwide. The phenomenon of shifting baselines syndrome (SBS) complicates our understanding these changes, masking the true scale human impacts. This study investigates long‐term ecological effects anthropogenic on New Zealand's over 800 years using fish otolith microchemical profiling and dynamic time warping across an entire stock unit. Results reveal a shift in snapper ( Chrysophrys auratus ; Sparidae) habitat‐use behaviour, transitioning from low‐salinity estuarine environments to higher‐salinity habitats, correlating with ongoing land‐use changes. coincided localised Industrial Revolution, which served as tipping point for widespread ecosystem transformation. By comparing current movement profiles historical baselines, we provide evidence address SBS guide conservation strategies. Re‐establishing pre‐industrial behaviours will indicate successful habitat restoration, promoting overall connectivity resilience. Our findings enable more effective restoration measures sustainable management practices, informing policies maintaining biodiversity function.

Abstract Unveiling the intricate relationships between animal movement ecology, feeding behavior, and internal energy budgeting is crucial for a comprehensive understanding of ecosystem functioning, especially on coral reefs under significant anthropogenic stress.

Individual processes scale up: these are the unique phenotypes that undergo selection, constitute populations, interact with other species, and thus shape biological reality. Understanding how individual animals differ in behaviour, is understanding behavioural individualities (personalities) emerge selected, leads us to a better of higher level systems, such as food webs, communities, or ecosystems, function. As amidst contemporary global environmental crisis, freshwater habitats their fish inhabitants disproportionately both biodiverse threatened, it crucial importance understand fishes cope anthropogenic change.

Abstract Background The invasion of non-native species into ecosystems is a growing human-induced problem. To control their spread and population growth, knowledge needed on the factors that facilitate or impede invasions. In animals, traits often associated with success are high activity, boldness, aggression. However, these also make individuals susceptible to predation, which could curb growth. We investigated if recent invader Baltic Sea, shrimp Palaemon elegans , differs in risk-taking from native shrimp, P. adspersus . recorded habitat choice, response perceived predation threat both species. Results found invading take greater risks than one; while adjusted its behaviour structure exposure predator, did not, it resumed normal activity sooner after threat. Despite risk taking by has grown rapidly during last two decades area now larger shrimp. Conclusions discuss plausible explanations for growth invader, including decline predatory fishes have reduced cost risk-taking, anthropogenic eutrophication increased food abundance allowed These results stress need assess optimality behaviours when investigating influence human-disturbed environments.

Due to its unforgiving nature, predation pressure exerts strong selection on the behaviour of prey animals. As a result, are forced balance conflicting demands successfully detecting and avoiding predators need engage in other fitness-related activities such as foraging, mating social behaviour. Here, we provide an overview role that individual predator avoidance decisions plays constraining behavioural phenotypes how past experience with risks shapes current (and future) trade-offs, physiological life history investments. Critically, access reliable risk assessment information allows respond spatially temporally variable risks. Uncertainty is expected limit ability make short- longer-term adjustments responses threats, potentially increasing indirect costs predation. We describe ‘landscape information’ which rely publicly available reduce uncertainty associated threats potential impact natural anthropogenic environmental factors may availability. Despite long tradition research into antipredator trade-offs made by animals, there remain number important unanswered questions.

Abstract With temperature being a crucial factor affecting the physiology of ectothermic animals, global warming will likely impact neural mechanisms aquatic organisms use to perceive their environment over generations. However, exposure elevated during specific life stages and across generations may confer fish resilience through phenotypic plasticity. In this study, we investigate effects developmental parental on brain activity response an olfactory cue in larval zebrafish, Danio rerio . We exposed parents reproduction offspring development control (28°C) or (30°C) observed telencephalon alarm using live calcium imaging. Parental decreased time till maximum regardless offspring’s temperature, revealing that thermal conditions can affect excitability circuitry. Furthermore, duration was affected by interaction between conditions, tending last longer when either were yet more similar experienced both offspring. This could represent anticipatory effect influencing match environment, early occurring within susceptible short window post-fertilization. Overall, our results suggest future predicted alter processes involved transmission show aid preparation respond stimuli changing environment.
