Prey species possess a variety of morphological, life history and behavioural adaptations to evade predators. While specific evolutionary conditions have led the expression permanent, non-plastic anti-predator traits, vast majority prey rely on experience express adaptive defences. ecologists identified highly sophisticated means through which naive can deal with predation threats, potential for death upon first encounter predator is still remarkably important unresolved issue. Here, we used...
Abstract Multidisciplinary approaches to conservation and wildlife management are often effective in addressing complex, multi-factor problems. Emerging fields such as physiology behaviour can provide innovative solutions strategies for target species systems. Sensory ecology combines the study of ‘how animals acquire’ process sensory stimuli from their environments, ecological evolutionary significance respond’ this information. We review benefits that bring by discussing case studies...
Predation is an important selection pressure acting on prey behavior. Although numerous studies have shown that when predation risk high, tend to increase vigilance and reduce foraging effort, until recently, few looked at how temporal patterns of influence the trade-off between antipredator The allocation hypothesis predicts should respond strongly predators are usually absent, as they can meet their energy demands during safe periods. In contrast, if almost always present, need forage...
The "dangerous niche" hypothesis posits that neophobia functions to reduce the cost of habitat use among animals exposed unknown risks. For example, more dangerous foraging or higher competition may lead increased spatial neophobia. Likewise, elevated ambient predation threats have been shown induce phenotypically plastic neophobic predator avoidance. In both cases, is argued living associated with ecological uncertainty. Here, we test shapes avoidance and in Trinidadian guppies. Guppies...
Abstract In response to acute predation threats, prey may sacrifice foraging opportunities in favour of increased predator avoidance. Under conditions high or frequent risk, such trade-offs lead reduced fitness. Here, we test the prediction that reduce costs associated with lost following threats by exhibiting short-term compensatory responses. semi-natural conditions, exposed female guppies Poecilia reticulate from and low risk sites one three levels threat (high, intermediate...
Within freshwater fishes, closely related species produce alarm cues that are chemically similar, leading to conserved antipredator responses. Similar conservation trends predicted for with geographically isolated populations. Here, we tested this hypothesis the guppy ( Poecilia reticulata Peters, 1859) from two populations within Aripo River, Trinidad. Free-ranging guppies in Lower (high-predation population) exhibited more risk-aversive inspection behaviour towards a fish predator model...
ABSTRACT Human actions, such as the construction of concrete retaining walls a form shoreline armouring, pose an increasing threat to freshwater ecosystems. Conventional armouring methods frequently result in habitat homogenization, which has detrimental effect on aquatic biodiversity. This laboratory study examined preferences four fish species (Yellow Perch [ Perca flavescens ], Bluegill Lepomis macrochirus Banded Killifish Fundulus diaphanus ] and Rock Bass[ Ambloplites rupestris ])...
Abstract While the use of aquatic protected areas that exclude angling might be considered an evolutionarily enlightened management approach to dealing with fisheries‐induced evolution (FIE), there is little empirical data on effectiveness this at maintaining diversity phenotypic traits within areas. In species paternal care, including largemouth bass ( Micropterus salmoides ), active nest‐guarding and aggression towards potential brood predators by males may render these individuals...
Selectively removing fish based on particular traits, such as body size, may shift trait abundance in the remaining population, resulting a phenomenon called fisheries-induced evolution. Recently, there is growing interest evaluating effects of evolution behaviour. Aquatic protected areas (APAs) have been designated some habitats efforts to prohibit harvesting and maintain natural ranges phenotypic variation for impacted species. Here, we attempted test whether APAs that all forms fishing an...
Abstract Fish are commonly sedated to render them immobile and thus easier handle for research, veterinary, aquaculture practices. Since sedation itself imposes a significant challenge on the targeted fish, selection of methods that minimize physiological behavioral disturbance recovery time is essential. Two popular include chemical tricaine methanesulfonate (MS‐222) electrosedation. Although many studies have already investigated consequences these methods, there limited research examining...
A better understanding of the environmental and genetic contribution to migratory behavior evolution traits linked migration is crucial for fish conservation fisheries management. Up date, a few genes with unequivocal influence on adoption alternative strategies have been identified in salmonids. Here, we used common garden set-up measure individual distances generally highly polymorphic brown trout Salmo trutta from two populations. Fish assumedly resident population showed clearly shorter...
To date, little attention has been devoted to possible complementary effects of multiple forms public information similar on the foraging behaviour predators. In order examine how predators may incorporate sources, we conducted a series predator attraction trials in Lower Aripo River, Trinidad. Four combinations visual (present or absent) and chemical cues from each two prey species were presented. The occurrences three locally abundant predatory present within 1 m radius cue introduction...
In order to investigate any size‐dependent differences between behavioural patterns, wild‐caught Hart's rivulus Rivulus hartii of varying sizes were exposed chemical alarm cues extracted from the skin conspecifics or heterospecific Poecilia reticulata , a tank water control, in series laboratory trials. response conspecific cues, R. subjects range body tested exhibited consistent, size‐independent antipredator behaviours that characterized by decreased locomotory activity and foraging levels...
