Their diet also consists of blackberry, greenbrier, and other woody and semi-woody plants. This removal effort was substantial considering 2013 camera trap surveys only identified 54 individuals on the refuge and density estimates suggested an island‐wide abundance of 120+ individual cats (Cove et al., 2018). Get PDF (1 MB) Abstract. We used LiDar data to calculate the mean elevation surrounding each camera trap site because elevation determines the susceptibility of sites to flooding and saltwater incursion from storms and hurricanes. Sylvilagus palustris (marsh rabbit) is found in parts of the southeastern United States. The marsh rabbit (Sylvilagus palustris) is a small cottontail rabbit found in marshes and swamps of coastal regions of the Eastern and Southern United States. MVC, BG, TRS, and AFO conceived and designed the research; MVC conducted fieldwork and collected data; MVC analyzed the data; TRS, BG, and AFO contributed materials/analysis tools and consulted on analyses; MVC wrote the initial draft of the manuscript; MVC, TRS, BG, and AFO revised and edited the manuscript. The full text of this article hosted at iucr.org is unavailable due to technical difficulties. We also calculated the relative differences in the number of individual cats detected at each site because cats were easily distinguishable based on pelage (Cove et al., 2018). It occupies coastal lowland areas, swamps, and rivers and is rarely found more than forty miles from the coast. A positive relative change in cats detected at each site (e.g., more individuals in 2015 relative to previous survey years) was negatively related to marsh rabbit patch colonization (β = −1.09 ± 0.60SE). Habitat destruction and fragmentation associated with residential and commercial construction activities over the past 20 years is responsible for the Lower Keys marsh rabbit™s endangered status. We sampled sites in the late dry and early transition into the rainy season, so most of the freshwater marshes were accessible. Marsh Rabbit (Sylvilagus palustris) Description. Cats were removed and new cats recruited at sites throughout the course of our study. marshes (USFWS, 1999). Marsh Rabbits are found in lowland, marshy areas near to a permanent source of water in south eastern USA. Cameras were left active at each site for 15–16 days, whereas total sampling occurred during 78 days in 2013 and 47 days in 2014 and 2015. Area (s) Where Listed As Endangered: The Lower Keys Marsh Rabbit ( Sylvilagus palustris hefneri) is a species of concern belonging in the species group "mammals" and found in the following area (s): Florida. The constant model for initial rabbit occupancy, colonization, extinction, and detection was more supported than including a year effect (ΔAIC = 3.98), so we did not include any covariates to distinguish 2013 from 2014 primary survey periods in further marsh rabbit models. We deployed camera traps to study free-ranging cats in National Wildlife Refuges and state parks on Big Pine Key and Key Largo and used spatial models to estimate cat population dynamics and stable isotope analyses to examine cat diets. We considered covariates to have strong effects if they were contained in multiple competing models and their 95% confidence intervals did not overlap zero (Burnham & Anderson, 2002). The camera trapping protocol that we used provided useful data on predators and their distribution for inferences in co‐occurrence models.
