Abstract An organism’s ability to disperse influences many fundamental processes, from speciation and geographical range expansion community assembly. However, the patterns underlying drivers of variation in dispersal across species remain unclear, partly because standardised estimates are rarely available. Here we present a global dataset avian hand-wing index (HWI), an estimate wing shape widely adopted as proxy for birds. We show that HWI is correlated with geography ecology 10,338...
Over the last few years, animal personality researchers have called for integrative approaches to study behavioral, immunological, and life-historical traits. This is because life history become implied as part of "pace-of-life" syndromes. Immune defense one traits that been suggested associate with traits, such boldness, mainly behavioral types may differ in parasite encounter rates. Here, we quantified narrow-sense heritabilities (h2 = VA/(VA + VR)) genetic (rA) phenotypic (rP)...
Abstract Stream ecosystems are affected by multiple abiotic stressors, and species responses to simultaneous stressors may differ from those predicted based on single‐stressor responses. Using 12 semi‐natural stream channels, we examined the individual interactive effects of flow level (low or high flow) addition fine sediments (grain size <2 mm) key ecosystem processes (leaf breakdown, algal biomass accrual) benthic macroinvertebrate fungal communities. Both had mostly independent...
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...
The rapid warming of the Northern hemisphere has especially challenged evolvability anadromous fish species, such as Atlantic salmon (Salmo salar), which must cope with drastically different environments depending on their life-history stage. We studied long-term trends in, and effects environmental factors traits on, growth rates in both freshwater ocean using c. 35,000 scale samples collected across 48 years from spawners returning to three tributaries subarctic River Teno northernmost...
Many salmonids, including brown trout ( Salmo trutta), demonstrate alternative migration strategies under different environmental conditions, and as such, they are assumed to be predominantly facultative. Through experimental breeding for two generations, we produced purebred, crossed, backcrossed groups of phenotypically resident, migratory, hybrid strains originating from a single watershed, raised them in common-garden conditions. We examined the spring smolt tendency crosses outdoor...
Fishing that selectively captures and removes fish based on their behavioural decisions is predicted to induce evolution towards timid stocks. Thus, offspring behaviour should associate with parental vulnerability angling. We examined phenotypic variation in juvenile brown trout (Salmo trutta) whose parents, representing a hatchery wild stock, were experimentally grouped relative The F 1 from highly vulnerable (HV) low (LV) parents reared common garden conditions together crossbred ×...
Behaviour that is adaptive in captivity may be maladaptive the wild and compromise postrelease survival of hatchery fish. The understanding behavioural variation displayed immediately after release could help to improve protocols development tests for assessing fitness fish reared releases. We characterized behaviour common-garden-raised offspring resident, captive-bred migratory, hybrid brown trout (Salmo trutta) two experiments: small artificial channels high low densities seminatural...
Wild, adfluvial brown trout (Salmo trutta) are iconic targets in recreational fisheries but also endangered many native locations. We compared how fishing and natural selection affect the fitness-proxies of from two pure angling-selected strains experimental crosses between an adfluvial, hatchery-bred strain three wild, resident strains. exposed age 1+ parr to predation risk under controlled conditions where their behaviour was monitored with PIT-telemetry, stocked 2+ fish lakes for fishing....
Abstract An organism’s ability to disperse influences many fundamental processes in ecology. However, standardised estimates of dispersal are rarely available, and thus the patterns drivers broad-scale variation remain unclear. Here we present a global dataset avian hand-wing index (HWI), an estimate wingtip pointedness widely adopted as proxy for flight efficiency birds. We show that HWI is correlated with geography ecology across 10,391 (>99 %) bird species, increasing at higher...
Abstract The behavior of organisms can be subject to human‐induced selection such as that arising from fishing. Angling is expected induce mortality on fish with bold and explorative behavior, which are behaviors commonly linked a high standard metabolic rate. We studied the transgenerational response brown trout ( Salmo trutta ) angling‐induced by examining metabolism 1‐year‐old parr between parents were or not captured experimental fly performed angling experiment both wild captive...
Behaviours that are adaptive in captivity may be maladaptive the wild and hence compromise after-release survival of hatchery fish. Understanding behavioural differences displayed straight after release could help improving protocols developing tests for assessing fitness fish reared releases. We characterized post-release behaviour two experiments using parr from wild, crossed strains brown trout (Salmo trutta): small-scale channels high low densities mesocosm streams. Our results show were...
Many animals rely heavily on visual cues from their environment, and therefore show circadian rhythmicity in behavioral activities. In group-living animals, individuals’ activity rhythms must be synchronized not only with diel light–dark cycle but also other group members. Increasing evidence has recently shown that behaviors of are consistent within individuals different between individuals, the sources consistency variation social context less known. Using radio frequency identification...
The supportive stocking programs that aim to promote fisheries may increase straying among sympatric but genetically diverged populations and compromise local adaptations. We employed recapture sample data on coded wire tagged brown trout (Salmo trutta m. lacustris) from three hatchery-reared strains study in which proportions they were represented as running spawners the area of River Juutuanjoki, northern Finland. More specifically, we analysed how migration tendency river varied relation...
ptive environment, but decrease their survival in the wild. While natural reproduction of most migratory populations is marginal, numerous original resident brown trout still occur small brooks. We have studied potential to use wild as genetic material increase diversity and adaptability hatchery broodstocks. Our results show that while interbreeding can improve predation avoidance, from even juvenile growth, migration tendency hybrid fish be compromised. In addition, both common garden...
