Assessing climate change associated sea‐level rise impacts on sea turtle nesting beaches using drones, photogrammetry and a novel GPS system
This work presents a novel combination of drone-based photogrammetry and a low-cost and portable real-time kinematic (RTK) GPS to create DTMs which are highly accurate (<10 cm error) and visually realistic and is a relevant tool in supporting the development of Specially Protected Areas. Expand
Ecosystem Function and Services of Aquatic Predators in the Anthropocene.
This work presents a social ecological framework for supporting adaptive management decisions involving APs in response to social and environmental change, and identifies outstanding questions to guide future research on the ecological functions and ecosystem services ofAPs in a changing world.

The effects of climate on annual variation in reproductive output in Snapping Turtles (Chelydra serpentina)
Of the above life-history traits, egg mass varied the least across years, and after warm autumns small turtles (225–285 mm carapace length) increased clutch mass by increasing clutch size but not egg mass, and in contrast, under the same conditions, large turtles increased clutchmass by increasing egg mass but not clutch size.

Where Have All the Turtles Gone, and Why Does It Matter?
Of the 356 species of turtles worldwide, approximately 61% are threatened or already extinct, and two notable characteristics of pre-Anthropocene turtles were their massive population sizes and correspondingly high biomasses, the latter among the highest values ever reported for animals. Expand
