Abstract The bigscale pomfret Taractichthys longipinnis is assumed to be a deep-pelagic fish that occurs primarily below 200 m but above the seafloor during the daytime. However, the lack of movement data for this and related species precludes precise ecological classification. Here, we used satellite telemetry to overcome historical methodological…

Abstract Objective: Swimming at the sea surface is a behavior exhibited by numerous shark species; however, depth distributions vary considerably by species, individual behavior states, and environmental conditions. Given the growing use of aerial surveillance tools for shark population monitoring and beach safety in New York coastal waters, our objective…

Abstract For highly mobile marine species such as pelagic elasmobranchs, the development of effective spatial management requires a comprehensive understanding of movement ecology. Research incorporating movement data across seasons and life stages, including reproductive states, is valuable for informing spatial management, yet is absent for most species. In the Northwest…

Abstract Background The lack of compatibility between acoustic telemetry equipment from different manufacturers has been a major obstacle to consolidating large collaborative tracking networks. Undisclosed encrypted signal coding protocols limit the use of acoustic telemetry to study animal movements over large spatial scales, reduce competition between manufacturers, and stifle innovation.…

Abstract Pop-off satellite archival tags (PSATs) have been increasingly deployed on marine megafauna to remotely monitor their movements, behavior, and environmental preferences. These tags have also allowed the occasional novel documentation of ecological interactions, such as predation on tagged animals. A PSAT deployed on a pregnant porbeagle Lamna nasus in…

Abstract After hatching, sea turtles leave the nest and disperse into the ocean. Many years later, they return to their natal coastlines. The period between their leaving and their returning to natal areas, known as the “Lost Years”, is poorly understood. Satellite tracking studies aimed at studying the “Lost Years”…

Introduction: To better understand Patagonian toothfish (Dissostichus eleginoides) movement and habitat in the Southwest Atlantic, fifty popup satellite archival tags (PSATs) were deployed off Davis Bank on North Scotia Ridge between 2019 and 2020 on individuals ranging from 97-139 cm total length. Methods: PSATs (18 Lotek Wireless PSATFLEX and 32…
Abstract We studied the migration of Magellanic penguins near the southern tip of the breeding distribution, and for the first time found evidence of partial migration for this species within the same colony. Forty-three percent of the penguins studied stayed within ~290 km of the colony (residents), while others went…
