Abstract We observed predation by river otters (Lontra canadensis) on large numbers of Florida cooter (Pseudemys floridana) and Florida softshell turtles (Apalone ferox) in two small lakes in North Central Florida, USA during a period of unusually low water levels. Carcasses were strewn on the shoreline and accumulated around floating boat docks, where some residents observed turtles being killed. We found 76 carcasses, including predominantly skeletons, and two live, severely injured turtles…

Depredation of gravid freshwater turtles by Raccoons (Procyon lotor)

During summer 2017, 19 dead or fatally wounded adult female turtles belonging to three at-risk species were found at a nesting site on the north shore of Lake Erie, Ontario, representing a spike in additive mortality for these populations, which could have long-term demographic consequences.

Investigation of multiple mortality events in eastern box turtles (Terrapene carolina carolina)

Investigation of health, disease, and death in free-living box turtles will improve baseline knowledge of morbidity and mortality, identify threats to survival, and promote the formation of effective conservation strategies.

Long-Term Trends in Ringed Sawback (Graptemys oculifera) Growth, Survivorship, Sex Ratios, and Population Sizes in the Pearl River, Mississippi

Abstract Effective management of long-lived species requires demographic and life-history data that are best acquired from long-term studies. The ringed sawback (Graptemys oculifera), endemic to the…

A BIBLIOGRAPHY ON THE NORTH AMERICAN RIVER OTTER Lontra canadensis

INTRODUCTION Since retiring to Florida I have had more free time to enjoy the wildlife around me. As I met people and we became acquainted they eventually discovered I was a zoologist. Many of these…

DETECTION OF RANAVIRUS USING BONE MARROW HARVESTED FROM MORTALITY EVENTS IN EASTERN BOX TURTLES (TERRAPENE CAROLINA CAROLINA)

Harvesting bone marrow from shells is easily performed and can serve as a means for biologists and wildlife veterinarians to improve postmortem surveillance for systemically distributed pathogens, including FV3.

SUMMER FEE;L)ING HABITS OF RIVER 01 1ER (LUTRA CANADENSIS) ON THE MENDOCINO NATIONAL FOREST, CALIFORNIA

The diet of otters was studied over one season on the Mendocino National Forest in northern California, with fish found to be the predominant food, occurring in 89.4% of the scats with a mean volume estimate of 63%.

PREDATION ON ALLIGATOR SNAPPING TURTLES (MACROCHELYS TEMMINCKII) BY NORTHERN RIVER OTTERS (LONTRA CANADENSIS)

These are the first reports of specific incidences of likely postembryonic predation of alligator snapping turtles found in association with northern river otters in Oklahoma in summer 2006.

Factors affecting the predation of otter (Lutra lutra) on European pond turtle (Emys orbicularis)

In fish ponds, the maintenance of a higher fish availability in ponds during winter makes it possible to avoid the need to acquire a proper hunting technique on turtle, indicated by the scarcity of primary fish food.

Application of Life-History Theory and Population Model Analysis to Turtle Conservation

Compared life tables from several turtle populations are compared using elasticity analysis, a method that calculates the proportional contribution of each vital rate (age-specific survival and fecundity) to the annual population multiplication rate, k [In (X) = r, the intrinsic rate of increase].

Effects of a sudden increase in natural mortality of adults on a population of the common snapping turtle (Chelydra serpentina)

Groundwater abstraction impacts on spring flow and base flow in the Hillsborough River Basin, Florida, USA

Groundwater abstraction has resulted in spring flow and groundwater base-flow declines in the Hillsborough River system of central Florida, USA. These declines have resulted in reduction of inflows…

Bioenergetics assessment of fish and crayfish consumption by river otter (Lontra canadensis): integrating prey availability, diet, and field metabolic rate

Otter daily energy expenditure is measured with the doubly labeled water method to develop a bioenergetics model for estimating monthly prey consumption and Meek’s crayfish (Orconectes meeki) catch-per-unit-effort was positively related to stream temperature, indicating that cray fish were more available during warmer months.
