Near Real-Time Telemetry Utilizing Satellite Communications. [PDF]

open access: yes, 1995
Abstract : Satellite transmission systems have proven themselves very effective in a variety of applications. One such application is the transmission of telemetry (TM) data and associated information in a near real time environment. This paper describes the satellite data relay system currently utilized by the Telemetry Data Center at Patuxent River ...

Trophic Ecology of Loggerhead Turtles (Caretta caretta) in Southern Brazil: Insights From Stable Isotopes

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT This study aimed to investigate the trophic ecology of loggerhead turtles recorded stranded along the Paraná coast in southern Brazil. Carbon and nitrogen stable isotopes were analysed in muscle tissues from 20 loggerhead turtles and in 69 specimens representing 12 prey species (molluscs, crustaceans and teleost fishes).

Radio-telemetry observations of the first 650 km of the migration of Bar-tailed Godwits Limosa lapponica from the Wadden Sea to the Russian Arctic [PDF]

open access: yes, 2002
In 1999 and 2000, 45 Bar-tailed Godwits Limosa lapponica were supplied with radio-transmitters during spring staging on the island Texel in the western Wadden Sea. With the use of Automatic Radio Tracking Stations (ARTS) on Texel and in south Sweden, and

Spatiotemporal Variation in Marine Mammal Antipredator Behaviors Resulting From a Predation Pinch Point

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Using 17 years of biologging data from 353 adult female northern elephant seals, we explored how seals modified their use of time and space when moving through nearshore areas where predation risk is high. We found that seals tended to depart at night, arrive during the day, and perform benthic dives along the continental shelf.

Harnessing Population Genomics, Gut Microbiota, and Environmental DNA Surveillance for the Conservation of Chinese Spotted Seals in a Changing World

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Marine mammals are sentinel species for ocean and human health. Multiple anthropogenic and environmental stressors threaten these organisms, particularly China's spotted seals, which have experienced significant decline over the past half‐century. Our review reveals low genetic diversity in Chinese spotted seal populations.

Neonate mortality in mountain caribou: Patterns of predation during onset of a wolf reduction program

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We used an individual‐based movement method, supported by camera trap data, to assess changes in neonate caribou mortality patterns before and after wolf reduction began in the Itcha‐Ilgachuz mountain caribou subpopulation range, British Columbia, Canada.

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...
