Between July 2003 and November 2004, 21 cownose rays Rhinoptera bonasus were tagged and tracked within Pine Island Sound estuary, Florida, using passive acoustic telemetry. Residence time of individuals ranged between 1 and 102 days. No relationship was detected between ray activity and tidal stage or time of day. Minimum convex polygons (MCP) and kernel utilization distributions (KUD) were calculated over several time frames to demonstrate the extent of an animal's home range and core areas of… 
Spatial Distribution and Long-term Movement Patterns of Cownose Rays Rhinoptera bonasus Within an Estuarine River
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
Spatial ecology of shark-like batoids in a large coastal embayment
The present study improves the understanding of shark-like batoid spatial ecology in nearshore waters and may provide useful information for the management of these populations.
Variation in cownose ray Rhinoptera neglecta abundance and group size on the central east coast of Australia.
Here, we provide baseline information about the relative abundance and group size of the Australian cownose ray Rhinoptera neglecta on the central east coast of Australia. Using drone monitoring over
Movement Patterns and Residence of Adult Winter Flounder within a Long Island Estuary
Insight is provided into winter flounder movements, residency, and stock structure in a coastal bay of Long Island and provide important information for management.
Residency and movement patterns of Arctic charr Salvelinus alpinus relative to major estuaries.
It was concluded that IFB S. alpinus spent a significant portion of their migration within or adjacent to the estuaries and had a restricted marine distribution within 30 km SLD of the river mouths.
Restricted movements and mangrove dependency of the nervous shark Carcharhinus cautus in nearshore coastal waters.
The strong affinity and residency of C. cautus within a mangrove-fringing coastline, emphasizes the importance of mangroves habitat to the species and suggests that such preferences can be used to design appropriate no-take zones for this species or others with similar habitat preferences.
Environmental Influences on the Spatial Ecology of Juvenile Smalltooth Sawfish (Pristis pectinata): Results from Acoustic Monitoring
Salinity electivity analysis demonstrated an affinity for salinities between 18 and at least 24 psu, suggesting movements are likely made in part, to remain within this range, although it remains unclear whether or not these movements are threatening recovery.
Variable migration patterns of whitespotted eagle rays Aetobatus narinari along Florida’s coastlines
This work suggests potential sub-population structuring of A. narinari may be occurring more than previously considered within Florida, which has significant conservation implications for this species.
Nearshore movement ecology of a medium-bodied shark, the creek whaler Carcharhinus fitzroyensis
The movement patterns exhibited by C. fitzroyensis suggest that this species has a moderately high degree of seagrass habitat specialisation, which may be an important foraging habitat for this species.
Habitat Ecology of the Bull Shark, Carcharhinus leucas, on Urban Coasts in Eastern Queensland, Australia
The habitat ecology of the euryhaline bull shark (Carcharhinus leucas) is poorly understood, yet vital for their conservation and management on our rapidly urbanising coastlines. This study


Residency and movement patterns of bonnethead sharks, Sphyrna tiburo, in a large Florida estuary
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
Distribution and abundance of the cownose ray,Rhinoptera bonasus, in lower Chesapeake Bay
Aerial surveys were conducted in the lower Chesapeake Bay during 1986–1989 to estimate abundance and examine the distribution of the cownose ray,Rhinoptera bonasus, during its seasonal residence,
Age and growth, movements and distribution of the cownose ray,Rhinoptera bonasus, in Chesapeake Bay
Ages were estimated for 115 of 899 cownose rays,Rhinoptera bonasus, collected primarily from commercial fishing gear, in lower Chesapeake Bay and vicinity from May through October, 1976–78. Age
Diel movement patterns of the Hawaiian stingray, Dasyatis lata: implications for ecological interactions between sympatric elasmobranch species
Comparison with previously published data on juvenile scalloped hammerhead sharks, Sphyrna lewini, in Kaneohe Bay revealed a high degree of overlap in habitat use and time of activity, suggesting possible ecological interactions between these two species.
Distribution, abundance, and behavior of the cownose ray, Rhinoptera bonasus (Mitchill 1815), in lower Chesapeake Bay
Aspects of the ecology of the cownose ray, Rhinoptera bonasus, in the lower Chesapeake Bay and its tributaries were studied using aerial surveys, biotelemetry, and examination of stomach contents.
Diel Movements of Bat Rays, Myliobatis californica, in Tomales Bay, California: Evidence for Behavioral Thermoregulation?
We used ultrasonic telemetry to examine movement patterns of 11 bat rays, Myliobatis californica, in Tomales Bay, California. Tomales Bay is long (20 km) and narrow (1.4 km), and is hydrographically
Distribution and habitat partitioning of immature bull sharks (Carcharhinus leucas) in a Southwest Florida estuary
The distribution and salinity preference of immature bull sharks were examined based on the results of longline surveys in three adjacent estuarine habitats in southwest Florida indicating the occurrence of size-based habitat partitioning.
Estimation of Shark Home Ranges using Passive Monitoring Techniques
We examined a population of blacktip sharks, Carcharhinus limbatus, within a coastal nursery area to define how individuals use the nursery habitat throughout the summer. We used a series of acoustic
Life history of the cownose ray, Rhinoptera bonasus, in the northern Gulf of Mexico, with comments on geographic variability in life history traits
Cownose rays in the Gulf of Mexico had lower estimates of DW∞ and K, and a higher theoretical longevity than their conspecifics in the western Atlantic Ocean, and attain maturity at a smaller size and earlier age than their counterparts in theWestern Atlantic Ocean.
