Many large marine predators make excursions from surface waters to the deep ocean below 200 m. Moreover, ability access meso- and bathypelagic habitats has evolved independently across mammals, reptiles, birds, teleost fishes, elasmobranchs. Theoretical empirical evidence suggests a number of plausible functional hypotheses for deep-diving behavior. Developing ways test among these will, however, require new quantify animal behavior biophysical oceanographic processes at coherent...
The Northwest Atlantic Ocean and Gulf of Mexico are among the fastest warming ocean regions, a trend that is expected to continue through this century with far-reaching implications for marine ecosystems. We examine distribution 12 highly migratory top predator species using predictive models project habitat changes downscaled climate models. Our predict widespread losses suitable most species, concurrent substantial northward displacement core habitats >500 km. These include up >70% loss...
Abstract Migratory behaviour patterns in animals are controlled by a complex genetic architecture. Rainbow trout ( Oncorhynchus mykiss ) is salmonid fish that spawns streams but exhibits three primary life history pathways: stream‐resident (fluvial), lake‐migrant (adfluvial) and ocean‐migrant (anadromous). Previous studies examining fluvial anadromous O . have identified several genes associated with divergence including the presence of an inversion within chromosome 5 (Omy05) appears to...
Abstract Wild capture fisheries produce 90 million tonnes of food each year and have the potential to provide sustainable livelihoods for nearly 40 people around world ( http://www.fao.org/3/a-i5555e.pdf ). After decades overfishing since industrialization, many global fish stocks recovered, a change brought about through effective management. We synthetic overview three approaches that managers use sustain stocks: regulating catch fishing mortality, effort spatial access. Within these...
Abstract The blue marlin ( Makaira nigricans ) is a highly migratory pelagic predator of tropical and subtropical seas. Information on the habitat use marine species fundamental to understanding their ecology population dynamics needed inform responsible management strategies. Using long‐term satellite tagging data set from International Game Fish Association Great Marlin Race, we examined how oxygen temperature influence horizontal vertical distributions in Central Pacific. Blue primarily...
Abstract Salmonid fishes may reside within or migrate between stream and lake habitats, undergo anadromous migrations freshwater the ocean. While degree of anadromy salmonids has been thoroughly compared, no analogous review examined use. To assess extent reliance on habitat in this family, we considered 16 species salmon, trout charr from genera Oncorhynchus , Salmo Salvelinus, comparing their (a) use lakes as spawning habitat, (b) rearing strategies lakes, (c) occurrence diversity...
Species distribution models (SDMs) are becoming an important tool for marine conservation and management. Yet while there is increasing diversity volume of biodiversity data training SDMs, little practical guidance available on how to leverage distinct types build robust models. We explored the effect different fit, performance predictive ability SDMs by comparing trained with four a heavily exploited pelagic fish, blue shark (Prionace glauca), in Northwest Atlantic: two fishery dependent...
Many predator species make regular excursions from near-surface waters to the twilight (200 1,000 m) and midnight (1,000 3,000 zones of deep pelagic ocean. While occurrence significant vertical movements into ocean has evolved independently across taxonomic groups, functional role(s) ecological significance these remain poorly understood. Here, we integrate results satellite tagging efforts with model predictions prey layers in North Atlantic Ocean determine whether distributions are...
Abstract Satellite transmitters that provide Doppler-based locations and telemeter data via the Argos satellite system have revealed a wealth of information on movement ecology diverse fauna such as marine mammals, turtles, sharks. In contrast, telemetry studies bony fishes almost exclusively relied pop-up archival tags (PSATs) use light-based geolocation to estimate movements. However, track reconstructions based light other sensor transmitted by PSATs exhibit positional error is orders...
ABSTRACT The louvar ( Luvarus imperialis ) is an exceedingly rare circumtropical fish species with a poorly understood ecology. Catch data from defunct drift gillnet fisheries provide unparalleled way to quantify the distributional dynamics of this that, as gelativore, almost never taken bycatch on fish‐ or squid‐baited longlines that dominate modern open ocean fisheries. Here, we present largest observational dataset assembled for louvar, combining > 30 years observer presence–absence...
Abstract The ocean’s twilight zone is a vast area of the global ocean that lies between sunlit surface waters and perpetually dark midnight zones, covering depths from ∼200 to 1000 m. Recent work in (or mesopelagic) has revealed unexpected biomass diversity may not only challenge scientific understanding marine systems but also provide new largely untapped resource for fisheries harvest. A key knowledge gap our mesopelagic how its food webs support foraging activity by commercially valuable,...

Large predators frequent the open ocean where subsurface light drives visually based trophic interactions. However, we lack knowledge on how achieve energy balance in unproductive prey biomass is minimal well-lit surface waters but high dim midwaters form of scattering layers. We use an interdisciplinary approach to assess bioenergetics layer forays by a model predator vary across biomes. show that mean metabolic cost rate daytime deep foraging dives layers decreases as much 26% from coastal...
The Mediterranean spearfish ( Tetrapturus belone ) is a highly migratory predator, also exploited by commercial and recreational fisheries although its catches are poorly reported. fishing pressure on this species currently unknown because catch landing data fragmentary. Furthermore, more ecological information (e.g. movements) needed to establish eventual management measures, ICCAT has not examined the population status yet. Understanding movements crucial for addressing conservation...
The pelagic thresher shark Alopias pelagicus is an understudied elasmobranch harvested in commercial fisheries of the tropical Indo-Pacific. species endangered, overexploited throughout much its range, and has a decreasing population trend. Relatively little known about movement ecology, precluding informed recovery strategy. Here, we report first results from individual outfitted with pop-up satellite archival transmitting (PSAT) tag to assess respect species’ physiology trophic ecology. A...
Abstract Background Fish geolocation methods are most effective when they customized to account for species behavior and study area characteristics. Here, we provide an example of customizing a hidden Markov model (HMM) reconstructing movement pathways high-latitude demersal fish in remote island chain using Pop-up Satellite Archival Tag (PSAT) data. Adult Pacific cod were tagged with PSATs while occupying winter spawning grounds the Aleutian Islands February 2019. We adapted application HMM...
Migration timing has evolved in many animals, allowing them to maximize breeding and feeding success by matching seasonal changes abiotic conditions resource pulses. These can shift with the climate, resulting mismatches between migrations availability unless populations respond through phenotypic plasticity or evolutionary adaptation. It is common, however, for factors unrelated climate affect phenology. Salmon are an exceptionally well-studied group of fishes whose serve as a template...
Abstract The management and conservation of tuna other transboundary marine species have to date been limited by an incomplete understanding the oceanographic, ecological socioeconomic factors mediating fishery overlap interactions, how these vary across expansive, open ocean habitats. Despite advances in fisheries monitoring biologging technology, few attempts made conduct integrated analyses at basin scales relevant pelagic highly migratory they target. Here, we use vessel tracking data,...
More than 200 million people in sub-Saharan Africa are infected with schistosome parasites. Transmission of schistosomiasis occurs when come into contact larval schistosomes emitted from freshwater snails the aquatic environment. Thus, controlling through augmenting or restoring their natural enemies, such as native predators and competitors, could offer sustainable control for this human disease. Fishes may reduce transmission directly, by preying on parasites, indirectly, competing food...
Aquatic organisms exhibit a variety of diel changes in vertical movement that are investigable through the use biotelemetry. While certain species do not change their movements between day and night, others migration (DVM) or diverse range activity patterns (DAPs). Consequently, day–night differences depth distribution may be stark easily detectable, more subtle difficult to identify. To augment discovery classification cryptic behavior, we developed utilized novel method analyzed entire...
