Climate change and decadal variability are impacting marine fish invertebrate species worldwide these impacts will continue for the foreseeable future. Quantitative approaches have been developed to examine climate on productivity, abundance, distribution of various species. However, it is difficult apply large numbers owing lack mechanistic understanding sufficient quantitative analyses, as well scientific infrastructure support more detailed studies. Vulnerability assessments provide a...
Knowledge of the three-dimensional movement patterns elasmobranchs is vital to understand their ecological roles and exposure anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses knowledge gap vertical movements by compiling first synthesis habitat use from data obtained deployment 989 biotelemetry tags 38 elasmobranch species. Elasmobranchs displayed high intra- interspecific variability in...
When identifying potential trophic cascades, it is important to clearly establish the linkages between predators and prey with respect temporal abundance, demographics, distribution, diet. In northwest Atlantic Ocean, depletion of large coastal sharks was thought trigger a cascade whereby predation release resulted in increased cownose ray which then caused on subsequent collapse commercial bivalve stocks. These claims were used justify development predator-control fishery for rays, "Save...
Despite recent advances in field research on white sharks (Carcharodon carcharias) several regions around the world, opportunistic capture and sighting records remain primary source of information this species northwest Atlantic Ocean (NWA). Previous studies using limited datasets have suggested a precipitous decline abundance from region, but considerable uncertainty these warrants additional investigation. This study builds upon previously published data combined with unpublished presents...
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...
White sharks, Carcharodon carcharias, are often described as elusive, with little information available due to the logistical difficulties of studying large marine predators that make long-distance migrations across ocean basins. Increased understanding aggregation patterns, combined recent advances in technology have, however, facilitated a new breadth studies revealing fresh insights into biology and ecology white sharks. Although we may no longer be able refer shark little-known, elusive...
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...
Abstract Many coastal shark species use shallow estuarine regions as nursery habitat, but there are considerable gaps in our understanding of the seasonal distribution and habitat patterns sharks within these systems. We compiled all available sampling data from Indian River Lagoon (IRL) along Florida's central Atlantic coast to examine bull Carcharhinus leucas . The synthesized this study spanned 30‐year period 1975–2005 included information on distribution, size structure, associations 449...
Abstract The distribution of marine species is changing as a direct result climate change. Large pelagic highly migratory (HMS), like tunas, billfishes, and sharks, are particularly sensitive to environmental change due their nature use large‐scale ocean features. These temporal spatial shifts likely reflected in the Atlantic HMS recreational fishery could have downstream effects on coastal communities. We utilized dockside intercept data from Pelagics Survey (LPS) 2002 2019, which conducts...
Abstract Seasonal variability in environmental conditions is a strong determinant of animal migrations, but warming temperatures associated with climate change are anticipated to alter this phenomenon unknown consequences. We used 40‐year fishery‐independent survey assess how changing has altered the migration timing, duration and first‐year survival juvenile bull sharks ( Carcharhinus leucas ). From 1982 2021, estuaries western Gulf Mexico (Texas) experienced mean increase 1.55°C autumn...
Abstract Bull Sharks Carcharhinus leucas in the Indian River Lagoon, Florida, have been documented to frequently occur human‐altered habitats, including dredged creeks and channels, boat marinas, power plant outfalls. The purpose of this study was examine short‐term movements age‐0 juvenile quantify extent which those altered habitats. A total 16 active acoustic tracks (2–26 h) were carried out with 9 individuals, a 10th individual fitted long‐term coded transmitter for passive monitoring by...
Abstract The combination of animal-borne telemetry and oceanographic sensor technologies creates an opportunity for marine animals to serve as ocean observing platforms (OOPs), carrying tags that record in situ data they naturally move. In this study, we create a blueprint shark OOP species selection, quantifying comparing the potential transmit collected data, environmental ranges various candidates are expected encounter, features may be resolve. Metrics satellite transmission probability,...
While significant progress has been made to characterize life history patterns, movement ecology, and regional estimates of abundance white sharks ( Carcharodon carcharias ) in the Western North Atlantic (WNA), patterns spatial distribution remain relatively unknown northern Gulf Maine. In this study, we utilize data collected from multiple acoustic telemetry projects 2012-2023 assess spatiotemporal along sections Maine coastline offshore waters. Acoustic receivers were deployed each year...
In recent years, white sharks (Carcharodon carcharias) have become more accessible to researchers off the northeastern U.S. as feeding aggregation sites emerged and population has increased. However, there been limited research on young-of-the-year (YOY) relative older age classes in this region. Previous indicated that YOY were most frequently observed New York Bight, suggesting region serves a nursery role. To further examine species' use of area, we deployed satellite acoustic tags ten...
Abstract Highly mobile species can be challenging for fisheries management and conservation due to large home ranges combined with dependence on discrete habitat areas where they easily targeted or vulnerable anthropogenic disturbances. Management of the Dusky Shark Carcharhinus obscurus in northwest Atlantic Ocean has been particularly species’ inherent vulnerability overfishing poorly understood associations. To better understand associations seasonal distributions, we telemetry remotely...
Abstract Spatial management for highly migratory species (HMS) is difficult due to many species’ mobile habits and the dynamic nature of oceanic habitats. Current static spatial areas fisheries in United States have been place extended periods time with limited data collection inside areas, making any analysis their efficacy challenging. modeling approaches can be specifically designed integrate from outside closed project distributions relative fishery. We developed HMS-PRedictive Modeling...
As highly mobile predators with extensive home ranges, some shark species often utilize a continuum of habitats across the continental shelf ranging from surf zone to open ocean. For many species, these cross-shelf distributions can change depending on ontogeny or seasonal conditions. Recent research has confirmed white ( Carcharodon carcharias ) summer nursery off Long Island, New York; however, habitat characterization this not yet been conducted nor fine-scale analysis vertical behavior....
