Abstract Most marine fish species express life-history changes across temperature gradients, such as faster growth, earlier maturation, and higher mortality at temperature. However, climate-driven effects on life histories population dynamics remain unassessed for most fishes. For 332 Indo-Pacific fishes, we show positive of body growth (but with decreasing asymptotic length), reproductive rates (including age-at-maturation), natural all species, the effect strength varying among...

Abstract Lake Erie walleyes Sander vitreus support important fisheries and have been managed as one stock, although preliminary tag return genetic analyses suggest the presence of multiple stocks that migrate among basins within into other portions Great Lakes. We examined temporal spatial movement abundance patterns walleye in three St. Clair with use sport commercial catch‐per‐unit effort (CPUE) data from 1990 to 2001. Based on summer returns, western basin migrated central eastern...

Abstract Offspring size determines offspring survival rates; thus, understanding factors influencing variability could elucidate variation in population dynamics. is influenced through multigenerational adaptation to local environments and within‐lifetime plastic responses environmental maternal effects among individuals. Moreover, may represent trade‐offs energy allocation within individuals that influence lifetime reproductive success. However, the mechanisms whereby conditions size, e.g.,...

Fish maturation schedules vary greatly among systems and over time, reflecting both plastic adaptive responses to ecosystem structure, physical habitats, mortality (natural fishing). We examined of commercially exploited lake whitefish ( Coregonus clupeaformis ) in the Laurentian Great Lakes (Lakes Michigan, Huron, Superior) by estimating ages lengths at 50% maturity, age-specific maturity ogives (age-specific probability being mature), probabilistic reaction norms (PMRNs; a metric that...

Eco-genetic individual-based models involve tracking the ecological dynamics of simulated individual organisms that are in part characterized by heritable parameters. We developed an eco-genetic model to explore and evolutionary interactions fish growth maturation schedules. Our is flexible allows for exploration effects rates (based on von Bertalanffy biphasic patterns), schedules reaction norm concepts), or both individual- population-level traits. In baseline simulations with rather...

Background. Total reduces improves osteoarthritic joint. Continuous increases movement, but there is some controversy regarding whether aggressive can improve or quality, it induces more pain.

Thermal stress is an important driver of species' distribution in the intertidal zone and, with forecasted increasing frequency extreme high temperatures associated climate change, likely to play even greater role future. To better understand scales at which thermal impacts organisms, we used biomimetic temperature loggers (robobarnacles) measure latitudinal variation estimated barnacle body (Tetraclita spp.) and evaluated influences large, geographic, smaller scale, microhabitat on...

The Pacific bluefin tuna (Thunnus orientalis, PBF), an iconic fisheries species, is heavily exploited and its biomass at a historically low level. To enhance effectiveness of management conservation, study was initiated to examine the demographic changes PBF between 2002 2015. Annual age compositions were estimated by applying empirical age-length key, based on ages lengths 892 fish, length frequencies observed among annual catches in northwestern spawning grounds located near Taiwan. Ages...

Abstract Maturation schedules, key determinants of fish stocks' harvest potential and population dynamics, are influenced by both plastic adaptive processes. Various indices used to describe maturation these have differential advantages for discriminating between However, sampling‐related biases associated with different not been fully evaluated. We analyzed three walleyes Sander vitreus in Lake Erie; Saginaw Bay, Huron; Oneida Lake, New York: age length at 50% maturity, midpoint...

Abstract Monitoring the thermal environment and responses of indicator species is fundamental for understanding predicting ecological consequences ongoing future environmental changes. With recent development miniaturized temperature sensors (e.g., iButtons), which can be incorporated into biomimetic loggers robolimpets), it possible to routinely obtain long‐term estimates body temperatures intertidal organisms. A crucial step in assembly these devices involves removing circuit board from an...

Abstract Faormamadinium based perovskites have been proposed to replace the methylammonium lead tri-iodide (MAPbI 3 ) perovskite as light absorbing layer of photovoltaic cells owing their photo-active and chemically stable properties. However, crystal phase transition from α -FAPbI non-perovksite δ still occurs in un-doped FAPbI films existence crack defects, which degrads responses. To investigate ratio (CR)-dependent structure excitonic characteristics polycrystalline thin deposited on...

We sought to evaluate the genetic variability of largehead hairtail (Trichiurus japonicus) in western North Pacific for purpose determining natural management units applicable fisheries regulation and ecological conservation. To achieve this, we analyzed two homologous segments each fish's mitochondrial DNA using AMOVA statistical model. In total, 180 samples were collected from continental shelves Japan, Yellow Sea (YS), East China Seas (ECS), Taiwan Strait (TS), South (SCS). general,...

Abstract Elucidating fishing effects on fish population dynamics is a critical step toward sustainable fisheries management. Despite previous studies that have suggested age or size truncation in exploited populations, other aspects of demography, e.g., via altering life histories and density, received less attention. Here, we investigated the adult demography shifting reproductive trade‐offs iconic, overexploited, Pacific bluefin tuna Thunnus orientalis . We found that, contrary to our...

Species-specific information on distribution and demographic patterns provides important implications for conservation fisheries management. However, such is often lacking morphologically-similar species, which may lead to biases in the assessments of these species even decrease effort towards sustainable Here, we aimed uncover range, population structure history four exploited Trichiurus cutlassfishes using genetics. These contribute substantial global catch, with a high proportion catch...
