The distributions of migratory species in the ocean span local, national and international jurisdictions. Across these ecologically interconnected regions, marine interact with anthropogenic stressors throughout their lives. Migratory connectivity, geographical linking individuals populations cycles, influences how spatial temporal dynamics affect animals scale up to influence population abundance, distribution persistence. Population declines many have led calls for connectivity knowledge,...
Abstract Aim Understanding the spatial ecology of animal movements is a critical element in conserving long‐lived, highly mobile marine species. Analyzing networks developed from six sea turtle species reveals connectivity and can help prioritize conservation efforts. Location Global. Methods We collated telemetry data 1235 individuals reviewed literature to determine our dataset's representativeness. used develop at different scales examine areas, connections, their geographic arrangement....
ABSTRACT Declines in absolute abundance and altered size distributions from size‐selective removals of market species pelagic apex predators tuna fisheries alters evolutionary characteristics populations ecosystem processes stability. Pelagic fishing at seamounts, where hyperstability may occur, can exacerbate declining have high bycatch groups that are highly vulnerable to overexploitation. Generalized additive mixed Poisson regression models (GAMMs) were fitted Hawaii longline fishery...
Air-breathing marine animals face a complex set of physical challenges associated with diving that affect the decisions how to optimize feeding. Baleen whales (Mysticeti) have evolved bulk-filter feeding mechanisms efficiently feed on dense prey patches. are central place foragers where oxygen at surface represents and depth acts as distance prey. Although hypothesized baleen will target densest patches anywhere in water column, density interact influence foraging behaviour is poorly...
A population of humpback whales (Megaptera novaeangliae) spends the austral summer feeding on Antarctic krill (Euphausia superba) along Western Peninsula (WAP). These acquire their annual energetic needs during an episodic season in high latitude waters that must sustain long-distance migration and fasting low-latitude breeding grounds. are broadly distributed continental shelf nearshore spring early summer, move closer to land late fall, where they overwinter under protective nutritional...
Understanding the areas used by migratory marine animals and their movements is critical in supporting management decisions that target conservation. This especially important for long-lived species with large geographic extents are more vulnerable to multiple threats. We conducted a literature review on data collected 173 mammal, fish, sea turtle, seabird determined tracking animal telemetry methods was most effective tool demonstrating ecological connectivity. From references included...

Resource managers rely on tools to enact ecosystem-based management (EBM) principles and frequently express frustration at the difficulty of use unreliability available tools. EBM tool developers lack consistent, long-term funding needed develop high-quality Through interviews, we determined several reasons for this problem including: (a) most are developed by academics rather than software professionals (b) offered no cost. These factors create a double-edged sword who cannot afford high...
Building on earlier work identifying Biologically Important Areas (BIAs) for cetaceans in U.S. waters (BIA I), we describe the methodology and structured expert elicitation principles used “BIA II” effort to update existing BIAs, identify delineate new score BIAs 25 cetacean species, stocks, or populations seven regions. represent areas times which are known concentrate activities related reproduction, feeding, migration, as well ranges of small resident populations. In this BIA II effort,...
<title>Abstract</title> Animal migrations are extensive, ubiquitous, and in decline. To effectively protect migratory species, it is often crucial to identify the interconnected sets of sites they rely upon. Gaps between primary ecological research synthesized information that useful policymakers has limited effective conservation long-distance migrants, particularly marine realm. By synthesizing 1304 references 1787 important develop model networks for 109 we show minimum extent megafauna...
We outline the rationale and process used by Cetacean Density Distribution Mapping (CetMap) Working Group to identify Biologically Important Areas (BIAs) for 24 cetacean species, stocks, or populations in seven regions within U.S. waters. BIAs are reproductive areas, feeding migratory corridors, areas which small resident concentrated. region-, species-, time-specific. Information provided each BIA includes following: (1) a written narrative describing information, assumptions, logic...
Low survival rates of juveniles in populations the endangered Hawaiian monk seal (Monachus schauinslandi) Northwestern Islands are believed to be leading cause species' decline. One hypothesis is that younger seals starving due poor foraging success. Because high mortality young poses a significant risk population-level survival, increased knowledge specifics weaned pup and juvenile paramount importance. We used telemetry data most recent movement modeling techniques compare seals' home...
Of the 18 species of odontocetes known to be present in Hawaiian waters, small resident populations 11 species—dwarf sperm whales, Blainville’s beaked Cuvier’s pygmy killer short-finned pilot melonheaded false pantropical spotted dolphins, spinner rough-toothed and common bottlenose dolphins—have been identified, based on two or more lines evidence, including results from small-boat sightings survey effort, photo-identification, genetic analyses, satellite tagging. In this review, we merge...
In this review, we merge existing published and unpublished information along with expert judgment to identify support the delineation of 12 Biologically Important Areas (BIAs) in U.S. waters Gulf Mexico for Bryde’s whales bottlenose dolphins.

We integrated existing published and unpublished information to delineate Biologically Important Areas (BIAs) for fin, gray, North Pacific right, humpback whales, belugas in U.S. waters of the Gulf Alaska. BIAs are delineated feeding, migratory corridors, small resident populations. Supporting evidence these came from aerial-, land-, vessel-based surveys; satellitetagging data; passive acoustic monitoring; traditional ecological knowledge; photoand genetic-identification whaling data,...
