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 Seagrass conservation is critical for mitigating climate change due to the large stocks of carbon they sequester in seafloor. However, effective and its potential provide nature-based solutions hindered by major uncertainties regarding seagrass extent distribution. Here, we describe characterization world’s largest ecosystem, located The Bahamas. We integrate existing spatial estimates with an updated empirical remote sensing product perform extensive ground-truthing seafloor 2,542...
Marine protected areas (MPAs) have emerged as potentially important conservation tools for the of biodiversity and mitigation climate impacts. Among MPAs, a large percentage has been created with implicit goal protecting shark populations, including 17 sanctuaries which fully protect sharks throughout their jurisdiction. The Commonwealth Bahamas represents long-term MPA sharks, following banning commercial longlining in 1993 subsequent designation sanctuary 2011. Little is known, however,...
Abstract Synthesis research in ecology and environmental science improves understanding, advances theory, identifies priorities, supports management strategies by linking data, ideas, tools. Accelerating challenges increases the need to focus synthesis on most pressing questions. To leverage input from broader community, we convened a virtual workshop with participants many countries disciplines examine how where can address key questions themes coming decade. Seven priority topics emerged:...
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...
White sharks ( Carcharodon carcharias ) are among the most widespread, charismatic, and studied predators in ocean. However, their conservation status is concerning many ocean sectors, notably Mediterranean Sea, which hosts one of least known endangered populations globally. Though they were historically abundant widely distributed region, white have declined to dangerously low abundance levels, impacted by centuries coastal and, more recently, industrial fishing. The IUCN lists this species...
The white shark (Carcharodon carcharias) is a globally distributed, ecologically important top predator whose biology and population dynamics are challenging to study. Basic biological parameters remain virtually unknown in the Mediterranean Sea due its historically low density, dwindling size, lack of substantial sightings. White sharks considered Critically Endangered Sea, recent analyses suggest that has declined by 52% 96% from historical levels different sectors (Moro et al., 2020)....
Top predators can exert strong influences on community structure and function, both via direct, consumptive effects, as well through non-consumptive, fear-based effects (i.e. predation risk). However, these are challenging to quantify, particularly for mobile in marine ecosystems. To advance this field of research, here we used baited remote underwater video stations (BRUVs) assess how the behavior fish species off Cape Cod, Massachusetts, was affected by exposure large sharks. We...
Marine protected areas are increasingly touted for their role in conserving large marine predators such as sharks, but efficacy is debated. Seventeen "shark sanctuaries" have been established globally, longline fishing continues within many jurisdictions, leading to unknown levels of bycatch mortality levels. Using public data from Global Fishing Watch and Regional Fisheries Management Organizations, we quantified eight shark sanctuaries estimated pelagic catch seven species. Sanctuary...
Catch-and-release fishing is an important component of ecotourism industries and scientific research worldwide, but its total impact on animal physiology, health survival understudied for many species fishes, particularly sharks. We combined biologging blood chemistry to explore how this fisheries interaction influenced the physiology two widely distributed, highly migratory shark species: blue (Prionace glauca) tiger (Galeocerdo cuvier). Nineteen sharks were caught by drum line or...
Animal-borne video camera systems have long-been used to capture the fine-scale behaviors and unknown aspects of biology marine animals. However, their utility serve as robust scientific tools in greater bio-logging research community has not been fully realized. Here we provide, for first time, an application 360-degree technology a organism, using large tiger shark proof-of-concept case study. Leveraging three-dimensional nature imaging technology, derived 224 seafloor habitat assessments...
The shortfin mako shark (Isurus oxyrinchus) is a highly mobile, coastal littoral, and epipelagic oceanic species broadly distributed in tropical, subtropical, temperate seas worldwide (Rigby et al., 2019). In recent years, there has been growing recognition of the impacts overfishing on populations, now listed as Endangered by International Union for Conservation Nature (IUCN) Critically Mediterranean Sea due to long-term continuing exploitation coupled with inadequate management (Walls...
Cetaceans are well-known for their intelligence, charismatic nature, and curiosity. Many species, particularly odontocetes, known to investigate manipulate novel objects they encounter. Yet, disentangling the drivers of these behaviors distinguishing between those that simply playful which serve a specific function remains challenging due lack direct observations detailed descriptions behaviors. This is true mysticetes such as humpback whales (Megaptera novaeangliae), records object use far...
Large marine predators often aggregate seasonally in discrete locations to take advantage of optimal foraging conditions, leading spatial and temporal variation their exposure on other species. However, our understanding the impacts this may have behavior physiology prey is poor, especially systems. Here, we evaluated non-consumptive effects potential large sharks (white sharks, Carcharodon carcharias (Linnaeus, 1758)) stress an economically important teleost, striped bass (Morone saxatilis...
