Understanding the factors shaping patterns of ecological resilience is critical for mitigating loss global biodiversity. Throughout aquatic environments, highly mobile predators are thought to serve as important vectors energy between ecosystems thereby promoting stability and resilience. However, role these play in connecting food webs flow remains poorly understood most contexts. Using carbon nitrogen isotopes, we quantified use several prey resource pools (small oceanic forage, large...
ABSTRACT Bycatch is the greatest threat facing marine mammals globally. In United States (US), there have been significant efforts to reduce mammal bycatch in commercial fisheries, particularly through implementation of 1994 amendments Marine Mammal Protection Act. However, trends US fisheries not evaluated over a decade. We assessed for 130 stocks 51 species from 1990 2017 according taxon, region and gear type based on National Fisheries Service Stock Assessment Reports using metric...
Abstract Animal dietary information provides the foundation for understanding trophic relationships, which is essential ecosystem management. Yet, in marine systems, high‐resolution diet reconstruction tools are currently under‐developed. This particularly pertinent large vertebrates, direct foraging behaviour difficult or impossible to observe and, due their conservation status, collection of stomach contents at adequate sample sizes frequently impossible. Consequently, diets many groups,...
Abstract Chondrichthyan fishes are among the most threatened vertebrates on planet because many species have slow life histories that outpaced by intense fishing. The Western Central Atlantic Ocean, which includes Greater Caribbean, is a hotspot of chondrichthyan biodiversity and abundance, but has been characterized extensive shark ray fisheries lack sufficient data for effective management conservation. To inform future research decisions, we analysed patterns in extinction risk,...
The diversity-stability relationship has been under intense scrutiny for the past decades, and temporal asynchrony is recognized as an important aspect of ecosystem stability. In contrast to relatively well-studied interannual seasonal asynchrony, few studies investigate role circadian cycles Here, we studied multifunctional redundancy diurnal nocturnal ant communities in four tropical rain forest sites. We analyzed how it was influenced by species richness, functional performance,...
Per- and polyfluoroalkyl substances (PFAS) enter the marine food web, accumulate in organisms, potentially have adverse effects on predators consumers of seafood. However, evaluations PFAS meso-to-apex predators, like sharks, are scarce. This study investigated occurrence five shark species from two ecosystems with contrasting relative human population densities, New York Bight (NYB) coastal waters The Bahamas archipelago. total detected (∑PFAS) concentrations muscle tissue ranged 1.10 to 58.5 ng g
Near-future climate change projections predict an increase in sea surface temperature that is expected to have significant and rapid effects on marine ectotherms, potentially affecting a number of critical life processes. Some habitats also undergo more thermal variability than others, the inhabitants therefore must be tolerant acute periods extreme temperatures. Mitigation these outcomes may occur through acclimation, plasticity or adaptation, although rate extent species' ability adjust...
Carbon dioxide (CO 2 ) in water has been explored for use as an invasive species deterrent system. To date, studies have not determined CO avoidance by fish flowing water, and this is a necessary step before operational system can be implemented. The objective of the study was to define how influences response bighead carp (Hypophthalmichthys nobilis) continuous plugs . A choice experiment which injected into channels annular flume completed. In trials when inner vein, spent less time vein...
The isotopic composition of tooth-bound collagen has long been used to reconstruct dietary patterns animals in extant and palaeoecological systems. For sharks that replace teeth rapidly a conveyor-like system, stable isotopes tooth (δ13 CTeeth & δ15 NTeeth ) are poorly understood lacking ecological context relative other non-lethally sampled tissues. This tissue holds promise, because shark jaws may preserve chronologies from which infer individual-level across range temporal resolutions....
Booralana nickorum sp. nov. is described from the deep-water slope of Exuma Sound, The Bahamas, depths 540 to 560 metres. It fourth species be assigned genus and second Western North Atlantic. can distinguished tricarinata Camp Heard, 1988 other by sub-triangular pleotelson uropodal exopod mature males being far longer than endopod, with both rami extending well beyond posterior margin pleotelson. Additionally, pleopods 3 4 lack a prominent angle at midpoint ramus.
Abstract As on land, oceans exhibit high temporal and spatial temperature variation. This “ocean weather” contributes to the physiological ecological processes that ultimately determine patterns of species distribution abundance, yet is often unrecognized, especially in tropical oceans. Here, we tested paradigm stability shallow waters (<12.5 m) across different zones latitude. We collated hundreds situ, temporal-frequency ocean time series globally produce an intuitive measure...
ABSTRACT The red rock crab, Cancer productus , is primarily harvested by a recreational fishery, with small commercial harvest in California. Although relatively large, meat yields are low because the legs small, and largely confined to claws. We investigated potential for claw‐only this species. hand removal used stone crab it caused > 90% post‐harvest mortality crabs. Inducing autotomy inserting spike into arthrodial membranes or cutting plane resulted high survival. recommend minimum...
Abstract This report updates our understanding of whale shark occurrences in The Bahamas by drawing upon a variety data sources. Our findings reveal previously unreported sighting locations, often associated with tourism activities, underscoring the pivotal role played nontraditional sources addressing knowledge gaps. These revelations emphasize ongoing necessity for monitoring efforts. Additionally, we have found cases that raise concerns related to unregulated human–shark interactions...
The pelagic zone of the ocean can be a challenging environment in which to conduct research and as result we lack robust baseline abundance diversity data, compared what is available more accessible coastal habitats, able track changes or stressors biota this environment. Many large-scale fisheries target fish, much information on these species based fisheries-dependent data that may biased towards hotspots commercially valuable fishes. Here, long-term video visual fish survey was conducted...
Abstract Fish aggregation devices (FADs) are used worldwide to enhance the efficiency of various fisheries. Devices consist a floating or subsurface component designed exploit natural fish behavior, using species’ attraction structure (e.g., Sargassum spp.) aggregate and increase capture success in open ocean environments. Concerns have arisen regarding scale management FAD-associated fisheries, however, FADs also introduces possibility for be as conservation tools study pelagic species...
