Estimating the absolute number of individuals in populations and their fecundity is central to
understanding the ecosystem role of species and their population dynamics as well as …

We document a tendency for published estimates of population size in sea turtles to be
increasing rather than decreasing across the globe. To examine the population status of the …

Long-term records of nesting numbers, or proxies to nesting numbers, show a precipitous
decline in the size of many sea turtle populations. Population declines are most frequently …

Accurate estimates of abundance are fundamental to the conservation of threatened
species, but are often difficult to obtain directly. Population size assessments of marine …

Mobile species often aggregate at predictable places and times to ensure that individuals
find mates and breed in suitable habitats. Sea turtles demonstrate this life history trait, which …

Although many species of marine mega-vertebrates are threatened as a result of human
activity, some populations are showing promising signs of recovery following decades of …

Understanding population status and trends is important for developing and evaluating
management and conservation actions for threatened species. Monitoring population status …

Diet items and habitat constitute some of the environmental resources that may be used
differently by individuals within a population. Long-term fidelity by individuals to particular …

Estimating population abundance is key for species of conservation concern. This is
particularly challenging for marine animals, like sea turtles, with ocean-scale distribution and …

For many marine megavertebrate species it is challenging to derive population estimates
and knowledge on habitat use needed to inform conservation planning. For marine turtles …
