Evolutionary impact assessment is introduced as a framework for quantifying the effects of 29 harvest-induced evolution on utility generated by fish stocks.
The conservation and management of endangered species requires information on their genetic diversity, relatedness population structure. main markers applied for these questions are microsatellites single nucleotide polymorphisms (SNPs), the latter which remain more resource demanding approach in most cases. Here, we compare performance two approaches, SNPs obtained by restriction-site-associated DNA sequencing (RADseq) 16 microsatellite loci, estimating differentiation three, small,...
Summary Pheromones are chemical signals that function not only as mate attractors, but may also relay important information to prospective mates. In order for the be reliable, signal must costly produce and this is likely result in condition dependent expression of signal. We present results from two experiments on grain beetle Tenebrio molitor examining phenotypic dependence pheromones patterns female preference pheromones. analysed measures immunocompetence: encapsulation response...
The immunocompetence handicap hypothesis postulates that secondary sexual traits are honest signals of mate quality because the hormones (e.g. testosterone) needed to develop have immunosuppressive effects. best support for predictions arising from so far comes studies insects, although they lack male-specific such as testosterone. In our previous studies, we found female mealworm beetles prefer pheromones immunocompetent males. Here, tested how juvenile hormone (JH) affects male investment...
Ecology Letters (2010) 13: 1449–1458 Abstract Trade‐offs between behavioural traits promoting high life‐history productivity and mortality may fuel the evolution of animal personalities. We propose that parasites, including pathogens, impose fitness costs comparable to those from predators, influence adaptiveness personality associated with (PAPs). Whether are adaptive or not also depend on individual immunological capacity. illustrate this using a conceptual example in which optimal level...
Managing fisheries resources to maintain healthy ecosystems is one of the main goals ecosystem approach (EAF). While a number international treaties call for implementation EAF, there are still gaps in underlying methodology. One aspect that has received substantial scientific attention recently fisheries-induced evolution (FIE). Increasing evidence indicates intensive fishing potential exert strong directional selection on life-history traits, behaviour, physiology, and morphology exploited...
Summary 1. According to a recent hypothesis, personality traits should form integrative pace‐of‐life syndromes with life‐history traits. Potential that explain variation are immune defence and growth rate. 2. We studied whether boldness, measured as hiding behaviour, is repeatable during ontogeny in the field cricket, Gryllus integer , if it relates efficiency of function (i.e. capacity encapsulate nylon implant), rate, developmental time size an adult. 3. Hiding behaviour was rank‐order...

Animals, including fish, display individually consistent behavioral differences that may affect an individual’s vulnerability not only to predation, but also fishing. Compared with complex natural environments, plain hatchery environments might induce development of behaviors increase fishing, which would in turn have major implications for the management stocks by supportive releases. We studied whether hatchery-reared brown trout (Salmo trutta) angling could be predicted rearing method...
Pheromones function not only as mate attractors, but they may also relay important information to prospective mates. It has been shown that vertebrates can distinguish, via olfactory mechanisms, major histocompatibility complex types in their However, whether pheromones transmit about immunocompetence is unknown. Here, we show female mealworm beetles (Tenebrio molitor) prefer from males with better immunocompetence, indicated by a faster encapsulation rate against novel antigen, and higher...
Crayfish plague epidemics (caused by Aphanomyces astaci) have been causing population collapses among native European crayfish stocks since the late 1800s. Recent indirect and direct evidence has shown that its virulence variable, with even acting as carriers. We tested differences in A. astaci under experimental conditions using both PsI- As-genotypes 3 Finnish noble Astacus astacus populations. infected adjusted quantities of zoospores monitored symptoms mortality crayfish. The...
According to recent studies on animal personalities, the level of behavioral plasticity, which can be viewed as slope reaction norm, varies among individuals, populations, and species. Still, it is conceptually unclear how interaction between environmental variation in cognition affect evolution plasticity expression personalities. Here, we (1) use literature review individual explain population (2) draw together empirically yet nontested, conceptual framework clarify these factors...
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)...
Populations of fishes provide valuable services for billions people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth intensifying resource use food, water, energy goods are compromising fish populations through a variety mechanisms, including overfishing, habitat degradation declines in water quality. The important challenges raised by these issues have been recognized led to considerable advances over past decades managing mitigating...
Candidate genes associated with migration have been identified in multiple taxa: including salmonids, many of whom perform migrations requiring a series physiological changes the freshwater–saltwater transition. We screened over 5,500 SNPs for signatures selection related to migratory behavior brown trout Salmo trutta by focusing on ten differentially migrating freshwater populations from two watersheds (the Koutajoki and Oulujoki). found eight outlier potentially versus resident life...
Historically, Finnish rivers supported vital populations of migratory salmonids. Presently, these species are more or less endangered due to extensive damming and hydropower production. In this article, we study the main legal scientific drivers for re-evaluating some existing operations in Finland. We argue that there is a need re-evaluation on basis obligations stemming largely from EU law new knowledge. Theoretically, our setting opens up classical adaptive governance problem how address...
Since food availability is known to affect both the precocious maturation and start of feeding migration in wild juvenile salmonids, we examined if a reduction otherwise plentiful hatcheries could improve tendency subsequent survival released Atlantic salmon (Salmo salar) smolts. A diet lipid content feed ration (FR) previous spring FR winter prior release proved efficient; spring-diet treatment halved proportion mature males autumn release, decreased latency before leaving stocking site.
