Accounting for emigration reveals high survival and bimodal size at departure from a loggerhead sea turtle (Caretta caretta) foraging area Accounting for emigration reveals high survival and bimodal size at departure from a loggerhead sea turtle (Caretta caretta) foraging area
The life history of hard-shelled sea turtles includes several ontogenetic shifts in habitat use and these complex permanent emigration patterns can impact estimates of stage-specific population rates, including survival. We developed several multistate mark recapture models to estimate survival of adult and juvenile loggerhead turtles from a coastal bay in the northern Gulf of America...
Tropicalization of the temperate zone: Spatiotemporal variability of winter warming and declining freeze days across the United States Tropicalization of the temperate zone: Spatiotemporal variability of winter warming and declining freeze days across the United States
We investigate changes in cool-season and winter daily minimum (Tmin) and maximum (Tmax) temperatures, and the occurrence of freeze days, from 1952 to 2024 across the conterminous United States (CONUS). Emphasis is placed on the tropical-temperate transition zone (TTTz) in the southeastern CONUS. During winter, ~70% of the land area exhibited Tmin warming rates exceeding those of Tmax...
Landscape connectivity and wildlife access to water across an international border: Barriers and opportunities for facilitating transboundary movement Landscape connectivity and wildlife access to water across an international border: Barriers and opportunities for facilitating transboundary movement
Rapid global acceleration in the construction of physical barriers along international borders has greatly influenced biodiversity and animal movement. Physical barriers can fragment landscapes, hinder access to essential resources, impact long-distance migrations, and inhibit dispersal and gene flow. The effects of physical barriers on animal movement and landscape connectivity can be...
