Urban coastal ecosystems are unique intersections of human development and biodiversity, and monitoring populations in these areas is critical to understanding ecosystem health and function.
This paper presents results from the youngest portion of this population, deceased fetuses and calves-of-the-year, to provide insights into breeding and calving seasonality for this endangered population.
This paper describes song production by the eastern North Pacific right whale (NPRW, Eubalaena japonica) in the southeastern Bering Sea. Songs were localized in real-time to individuals using sonobuoys.
Daniel J. Vos, Kim E. W. Shelden, Nancy A. Friday, and Barbara A. Mahoney researched and combined beluga age estimates, from the teeth of hunted and stranded belugas during the period 1992–2001, with additional teeth collected up to June 2015.
We assessed 21 trace metals in green turtle scute and red blood cell samples collected find evidence that green turtle TM concentrations can differ between urbanized habitats and that long-term monitoring of these green turtles may be necessary.
We estimate sea turtle densities, and describe trends based on sea turtle observations from 13 years of towed-diver surveys covering 7,300+ linear km, and more than 3,400 green and hawksbill sea turtles.
