Florida Keys Mole Skink Florida Keys mole skink Plestiodon egregius egregius (Photo by Kevin Enge, FWC) Taxonomic Classification Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Squamata Family: Scincidae Genus/Species: Plestiodon egregious Subspecies: Plestiodon egregious egregious Common Name: Florida Keys mole skink Listing Status Federal Status: Not Listed FL Status: State Species of Special Concern FNAI Rank: G4T2/S2 (Globally: Apparently Secured, Sub sp. Imperiled/ State: Imperiled) IUCN Status: Not ranked Physical Description The Florida Keys mole skink is a small brown lizard that can reach a length of five inches (12.7 centimeters) (Christman 1992). This species has a brownish-colored body with a pink-tinted tail, and two or more light-colored lines that extend from the head down the body, sometimes extending to the tail. The legs of this species are small and have five toes on each foot (Florida Natural Areas Inventory 2001). Florida Keys Mole Skink 1 | Page Life History The diet of the Florida Keys mole skink primarily consists of small arthropods including roaches, spiders, and crickets (Mount 1963). Little is known about the reproduction of the Florida Keys mole skink. Females lay a clutch of three to five eggs in underground nests between the months of April and June (Mount 1963, Bartlett and Bartlett 1999). Eggs hatch 31-51 days after being laid. Females remain with the eggs until they hatch for protection. This species usually reaches maturity at the age of one year (Christman 1992). Habitat & Distribution The Florida Keys mole skink is a secretive species that inhabits sandy areas under rocks, leaf litter, and tidal wracks (line of washed up vegetation on the beach that consists of dead seaweed and marsh grass) (Carr 1940, Duellman and Schwartz 1958, Christman 1992). This species can be found in the Florida Keys in Dry Tortugas, Key West, Stock Island, Middle Torch Key, Big Pine Key, Key Vaca, Grassy Key, Upper Matecumbe Key, Indian Key, and Key Largo (Christman 1992). Threats The Florida Keys mole skink faces many threats to its populations such as the destruction of habitat in the Florida Keys. Development along the shoreline has been the main cause of the destruction of habitat. Severe hurricanes are also a threat to the mole skink because of storm surge, flooding, and increased wind speeds (Mount 1963). Potential sea level rise could also affect mole skink habitat found along the shoreline and other low lying areas due to inundation of water. Conservation & Management The Florida Keys mole skink is protected as a State Species of Special Concern by Florida’s Endangered and Threatened Species Rule. -Biological Status Review (BSR) -Supplemental Information for the BSR Florida Keys Mole Skink 2 | Page Other Informative Links Florida Natural Areas Inventory References Bartlett, R.

  • Multi-National Conservation of Alligator Lizards
    MULTI-NATIONAL CONSERVATION OF ALLIGATOR LIZARDS: APPLIED SOCIOECOLOGICAL LESSONS FROM A FLAGSHIP GROUP by ADAM G. CLAUSE (Under the Direction of John Maerz) ABSTRACT The Anthropocene is defined by unprecedented human influence on the biosphere. Integrative conservation recognizes this inextricable coupling of human and natural systems, and mobilizes multiple epistemologies to seek equitable, enduring solutions to complex socioecological issues. Although a central motivation of global conservation practice is to protect at-risk species, such organisms may be the subject of competing social perspectives that can impede robust interventions. Furthermore, imperiled species are often chronically understudied, which prevents the immediate application of data-driven quantitative modeling approaches in conservation decision making. Instead, real-world management goals are regularly prioritized on the basis of expert opinion. Here, I explore how an organismal natural history perspective, when grounded in a critique of established human judgements, can help resolve socioecological conflicts and contextualize perceived threats related to threatened species conservation and policy development. To achieve this, I leverage a multi-national system anchored by a diverse, enigmatic, and often endangered New World clade: alligator lizards. Using a threat analysis and status assessment, I show that one recent petition to list a California alligator lizard, Elgaria panamintina, under the US Endangered Species Act often contradicts the best available science.

Instead, we examine the rate of production (productivity of Biological Sciences, University of Reading, hereafter) calculated as the total mass of offspring produced in a year. We test ReadingRG6 6AS, UK whether productivity is influenced by proxies of adult mortality rates such as insularity and fossorial habits, by measures of temperature such as environmental and body temperatures, mode of reproduction and activity times, and by environ- mental productivity and diet. We further examine whether low productivity is linked to high extinction risk. Location World-wide. Methods We assembled a database containing 551 lizard species, their phyloge- netic relationships and multiple life history and ecological variables from the lit- erature. We use phylogenetically informed statistical models to estimate the factors related to lizard productivity. Results Some, but not all, predictions of metabolic and life-history theories are supported. When analysed separately, clutch size, relative clutch mass and brood frequency are poorly correlated with body mass, but their product – productivity – is well correlated with mass. The allometry of productivity scales similarly to metabolic rate, suggesting that a constant fraction of assimilated energy is allocated to production irrespective of body size.

  • Home Range, Survival, and Activity Patterns of the Southeastern Pocket Gopher: Implications for Translocation
    Articles Home Range, Survival, and Activity Patterns of the Southeastern Pocket Gopher: Implications for Translocation Ashley E. Warren, L. Mike Conner, Steven B. Castleberry,* Daniel Markewitz A.E. Warren, S.B. Castleberry, D. Markewitz Warnell School of Forestry and Natural Resources, University of Georgia, Athens, Georgia 30602 Present address of A.E. Warren: Florida Fish and Wildlife Conservation Commission, Panama City, Florida 32409 L.M. Conner Joseph W. Jones Ecological Research Center at Ichauway, Newton, Georgia 39870 Abstract The southeastern pocket gopher Geomys pinetis is absent from a large portion of its historical range. Translocation may represent a viable management technique to reestablish populations into suitable habitat. However, several aspects of the species’ ecology are poorly understood, making development of an effective translocation approach challenging. Therefore, we used radiotelemetry to examine home range, survival, dispersal, and daily activity patterns of the southeastern pocket gopher in southwestern Georgia. We measured soil and vegetation characteristics within individual home ranges and examined relationships between home range size, habitat variables, and body mass. Mean home range size of 17 radio-tagged pocket gophers was 921.9 m2 (range ¼ 43.4–2246.8 m2). Home range size was positively related to body mass, percent silt at a depth of 25 cm, and soil carbon content at 75 cm and was negatively related to percent sand at 25 cm, percent clay at 50 cm, and ground cover of grasses other than wiregrass Aristida beyrichiana. Survival rate was 0.78 (range ¼ 0.50–1.00) over the 51-wk study, and we documented predation, likely by avian predators, on two individuals.

    ECOLOGY OF THE SOUTHEASTERN POCKET GOPHER (GEOMYS PINETIS) IN SOUTHWESTERN GEORGIA by ASHLEY ERIN WARREN (Under the Direction of Steven B. Castleberry) ABSTRACT From September 2012 through December 2013 I used telemetry to investigate home range, survival, and movement patterns of southeastern pocket gophers (Geomys pinetis) in Southwestern Georgia. I also used a modeling approach to determine whether vegetation or soil characteristics best predicted gopher presence and developed a predictive model using combinations of vegetation and soil variables. Mean home range size of 17 gophers was 921.9 m2 (range = 43.4-2246.8 m2). Home range size was positively associated with body mass, percent silt, and soil carbon, and negatively associated with percent sand, percent clay, and grass ground cover. Two individuals were predated and survival rate was 0.78 over 51 weeks. Three individuals dispersed, with maximum dispersal distance of 319.1 m (range = 143.2-319.1 m). Pocket gophers exhibited greater activity at 00:00-4:00 and 16:00-20:00. Soil predicted presence better than vegetation, and the best predictive model combined percent clay, percent silt, pH, nitrogen, and carbon.

The remaining 16% (55,101 ac; 22,299 ha) are other private lands. Habitat Description FNAI type: Scrub This habitat occurs on areas of deep, well-drained, infertile sandy soils that are typically white or near white. Scrub has a patchy distribution and occurs in both inland and coastal areas, from the panhandle through subtropical regions of the peninsula. The largest and most important patches of Scrub occur along the central ridge of the peninsula near Ocala and in Polk and Highlands counties. This habitat is fire-dependent; it is maintained by fires that are usually very hot or intense, but occur infrequently at intervals of 10-20 years, or more. Generally, Scrub is dominated by evergreen, or nearly evergreen, oaks and/or Florida rosemary, with or without a pine overstory. A relatively large suite of plant species is endemic to Scrub (e.g., scrub holly and inopina oak); the rarest endemic plant species are restricted to the Lake Wales area of the central ridge (e.g., pygmy fringe tree and scrub plum).
