Hard prey specialists or opportunistic generalists? An examination of the diet of the cownose ray, Rhinoptera bonasus
- A. Collins, M. Heupel, R. Hueter, P. Motta
- Environmental Science
- 21 February 2007
Although R. bonasus has been characterised as a hard prey specialist, these results suggest it may behave as an opportunistic generalist, modifying feeding behaviour to consume readily available prey.
Residency and movement patterns of bonnethead sharks, Sphyrna tiburo, in a large Florida estuary

- 5 June 2006
The use of a coastal estuary by bonnethead sharks, Sphyrna tiburo, was examined by acoustic monitoring, gillnet sampling and tag- recapture studies. Acoustic monitoring data were used to define the…
Variation in the performance of acoustic receivers and its implication for positioning algorithms in a riverine setting

- 1 March 2008
The performance of an array of data-logging single frequency acoustic receivers in the Caloosahatchee River (Florida, USA) was examined and the results incorporated into a positioning algorithm for…
Residence and movement patterns of cownose rays Rhinoptera bonasus within a south‐west Florida estuary
- A. Collins, M. Heupel, P. Motta
- Environmental Science
- 1 October 2007
Data show that cownose rays travel extensively throughout this estuary, yet may remain within very small areas for extended periods, as mobile, pelagic swimmers capable of traversing large distances.
Spatial Distribution and Long-term Movement Patterns of Cownose Rays Rhinoptera bonasus Within an Estuarine River
- A. Collins, M. Heupel, C. Simpfendorfer
- Environmental Science
- 2 October 2008
Passive acoustic telemetry was used to monitor the movements of cownose rays (Rhinoptera bonasus) within the Caloosahatchee River estuary in Southwest Florida. Twelve rays were tracked within the…
Long-term presence and movement patterns of juvenile bull sharks, Carcharhinus leucas, in an estuarine river system
- M. Heupel, M. Heupel, C. Simpfendorfer
- Environmental Science
- 17 February 2010
Long-term consistent use of this habitat by young C. leucas suggests this population is highly dependent on the Caloosahatchee River as a nursery area, suggesting further diurnal patterns in habitat use.
Partial migration of the nurse shark, Ginglymostoma cirratum (Bonnaterre), from the Dry Tortugas Islands

Some overwintered and some resumed courtship in June, demonstrating both resident and migratory contingents within their population, partial migration and an ability to navigate with high spatial and temporal precision.
An investigation into the habitat, behavior and opportunistic feeding strategies of the protected goliath grouper (epinephelus itajara)
- A. Collins
- Environmental Science
- 2014
This study studies the distribution and habits of Atlantic Goliath Grouper Epinephelus itajara in the eastern Gulf of Mexico and finds abundance, size distribution, and habitat association are regulated by conventional tagging methods.
Acoustic telemetry array evolution: From species- and project-specific designs to large-scale, multispecies, cooperative networks

Reef relief and volume are predictors of Atlantic goliath grouper presence and abundance in the eastern Gulf of Mexico
- A. Collins, L. Barbieri, R. McBride, E. McCoy, P. Motta
- Environmental Science
- 2015
The strong site fidelity of goliath grouper combined with their continuous and predictable association with artificial reefs allows for relatively efficient monitoring of individuals within a given region; however, these traits also increase vulnerability to exploitation and underline the need for cautious management.
