Prey Density Threshold and Tidal Influence on Reef Manta Ray Foraging at an Aggregation Site on the Great Barrier Reef.

Autor: Asia O Armstrong, Amelia J Armstrong, Fabrice R A Jaine, Lydie I E Couturier, Kym Fiora, Julian Uribe-Palomino, Scarla J Weeks, Kathy A Townsend, Mike B Bennett, Anthony J Richardson

Publikováno v: PLoS ONE, Vol 11, Iss 5, p e0153393 (2016)

Large tropical and sub-tropical marine animals must meet their energetic requirements in a largely oligotrophic environment. Many planktivorous elasmobranchs, whose thermal ecologies prevent foraging in nutrient-rich polar waters, aggregate seasonall

Publikováno v: PLoS ONE, Vol 8, Iss 10, p e77152 (2013)

Assessing the trophic role and interaction of an animal is key to understanding its general ecology and dynamics. Conventional techniques used to elucidate diet, such as stomach content analysis, are not suitable for large threatened marine species.

Oceanographic drivers of near-colony seabird foraging site use in tropical marine systems

Autor: Scarla J. Weeks, Fiona McDuie, Bradley C. Congdon

Publikováno v: Marine Ecology Progress Series. 589:209-225

Wedge-tailed shearwaters of Australia’s southern Great Barrier Reef (GBR), obtain food for their chicks on short trips adjacent to the breeding colony. GPS tracking (from February to April in 2013 and 2014) indicated that most trips were of 1 d dur

Remote Sensing; Volume 7; Issue 3; Pages: 3138-3152

Manta rays are classified as Vulnerable to Extinction on the IUCN Red List for Threatened Species. In Australia, a key aggregation site for reef manta rays is Lady Elliot Island (LEI) on the Great Barrier Reef, ~7 km from the shelf edge. Here, we inv

Publikováno v: Journal of Geophysical Research: Oceans. 120:1741-1770

A semianalytical ocean color inversion algorithm was developed for improving retrievals of inherent optical properties (IOPs) in optically shallow waters. In clear, geometrically shallow waters, light reflected off the seafloor can contribute to the
