Life history can help dictate resilience in the face of decline, and therefore understanding attributes such as sexual size dimorphism, site fidelity, and survival rates are essential. Australia is well-known for its diversity of scincid lizards, but we have little detailed knowledge of the life histories of individual scincid species. To examine the life history of the Coppertail Skink (Ctenotus taeniolatus), which uses scattered surface rocks as shelter, we estimated survival rates, growth rates, and age at maturity during a three-year capture-mark- recapture study. We captured mostly females (> 84%), and of individuals captured more than once, we captured 54.3% at least twice beneath the same rock, and of those, 64% were always beneath the same rock (up to five captures). -
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. -

Somma Department of- Zoology University of Florida Gainesville, FL 32611 Amphisbaenids, or worm lizards, are a small enigmatic suborder of reptiles (containing 4 families; ca. 140 species) within the order Squamata, which include~ the more speciose lizards and snakes (Gans 1986). The name amphisbaenia is derived from the mythical Amphisbaena (Topsell 1608; Aldrovandi 1640), a two-headed beast (one head at each end), whose fantastical description may have been based, in part, upon actual observations of living worm lizards (Druce 1910). While most are limbless and worm-like in appearance, members of the family Bipedidae (containing the single genus Sipes) have two forelimbs located close to the head. This trait, and the lack of well-developed eyes, makes them look like two-legged worms. -

Evolution of Limblessness
Evolution of Limblessness Evolution of Limblessness Early on in life, many people learn that lizards have four limbs whereas snakes have none. This dichotomy not only is inaccurate but also hides an exciting story of repeated evolution that is only now beginning to be understood. In fact, snakes represent only one of many natural evolutionary experiments in lizard limblessness. A similar story is also played out, though to a much smaller extent, in amphibians. The repeated evolution of snakelike tetrapods is one of the most striking examples of parallel evolution in animals. This entry discusses the evolution of limblessness in both reptiles and amphibians, with an emphasis on the living reptiles. Reptiles Based on current evidence (Wiens, Brandley, and Reeder 2006), an elongate, limb-reduced, snakelike morphology has evolved at least twenty-five times in squamates (the group containing lizards and snakes), with snakes representing only one such origin. These origins are scattered across the evolutionary tree of squamates, but they seem especially frequent in certain families. In particular, the skinks (Scincidae) contain at least half of all known origins of snakelike squamates. But many more origins within the skink family will likely be revealed as the branches of their evolutionary tree are fully resolved, given that many genera contain a range of body forms (from fully limbed to limbless) and may include multiple origins of snakelike morphology as yet unknown. These multiple origins of snakelike morphology are superficially similar in having reduced limbs and an elongate body form, but many are surprisingly different in their ecology and morphology. This multitude of snakelike lineages can be divided into two ecomorphs (a are surprisingly different in their ecology and morphology. -
Lizard ID Guide
Lizards of Anderson County, TN Lizards are extraordinary gifts of nature. World-wide there are close to 6,000 species. The United States is home to more than100 native species, along with many exotic species that have become established, especially in Florida. Tennessee has 9 species, 6 of which are listed for Anderson County. Some are fairly widespread and easy to observe, such as the Common Five-lined Skink below. Unfortunately, the liberal use of pesticides, combined with predation by free roaming house cats have taken a heavy toll on our lizard populations. Most lizards are insect eating machines and their ecological services should be promoted through backyard and schoolyard wildlife habitat projects. Lizard watching is great fun, and over time, observers can gain interesting insights into lizard behavior. Your backyard may be a good place to start your lizarding career. This guide will be helpful for identifying our local lizards and will also provide you with examples of lizard behaviors to observe. Some species must be captured—this can be challenging—to insure accurate identification. Please see the back page for more resources. Lizarding Lizard watching, often referred to as lizarding, will likely never be as popular as bird watching (birding), but there is an advantage to being a “lizarder.” Unlike birders, you don’t need to be an early riser. Bright sunny days with warm temperatures are the keys for successful lizarding, but like birding, close-up binoculars are helpful. A lizard’s life centers around three performance activities: 1) avoiding predators, 2) feeding, and 3) reproduction. Lizard performance is all about optimal body temperature. -

Ecology, Life-History, and Behavior in the Australian Scincid Genus Egernia, with Comments on the Evolution of Complex Sociality in Lizards
Herpetological Monographs, 17, 2003, 145–180 Ó 2003 by The Herpetologists’ League, Inc. ECOLOGY, LIFE-HISTORY, AND BEHAVIOR IN THE AUSTRALIAN SCINCID GENUS EGERNIA, WITH COMMENTS ON THE EVOLUTION OF COMPLEX SOCIALITY IN LIZARDS 1 DAVID G. CHAPPLE School of Botany and Zoology, Australian National University, Canberra ACT 0200, Australia ABSTRACT: Squamate reptiles generally have been ignored in the search for a unified theory for the evolution of sociality due to the perception that they exhibit little social behavior beyond territoriality and dominance hierarchies and display polygynous mating systems. However a growing body of research has revealed unsuspected levels of social complexity and diversity in mating systems within the squamate lineage, particularly among the members of the Australian Scincid genus Egernia. Several species of Egernia are amongst the most highly social of all squamate reptiles, exhibiting stable social aggregations and high levels of long-term social and genetic monogamy. Social complexity is widespread within the Egernia genus, with reports of social aggregations in 23 of the 30 described species. The purpose of this review was to examine the potential for the Egernia genus as a model system for study of the evolution of sociality and monogamy within squamate reptiles. Current evidence indicates there is substantial variability in social complexity both within and between species, with social organization covering the spectrum from solitary to highly social. Four highly social Egernia species are known to live in stable social aggregations consisting of closely related individuals (adults, subadults, juveniles; i.e., ‘family’ groups) that appear to utilize chemical cues to recognize group members (kin recognition). -

Group-living in the Australian skink, Egernia stokesii. A thesis submitted for the degree of Doctor of Philosophy by Elvira Jane Lanham Bachelor ofEnvironmental Science (Hons) (University of Wollongong) School of Biological Sciences Flinders University of South Australia May, 2001. For Dion, wish you were here. II Author's Declaration I certify that this thesis does not incorporate, without acknowledgment, any material previously submitted for a degree or diploma in any university; and that to the best of my knowledge and belief it does not contain any material previously published or written by another person except where due reference is made in the text. Elvira Jane Lanham. May, 2001. l 11 Abstract. Until recently, reptiles have been thought to exhibit little more than rudimentary sociality. Males of most species studied so far are either solitary or defend territories, containing one or more females. Some species have developed complex visual displays to maintain their territory and tolerance of other males is limited to non breeding juveniles. Much of the ideas about lizard social behaviour have come from the study of visually-orientated species such as the iguanids and agamids. Little is known about the more fossorial species, but astheir behaviour receives more attention there appears to be more diversity among these taxa than first thought. Egernia stokesii displays unusually stable, long-term group fidelity, with gi:oups in one well studied population ranging from 2-17 individuals (Duffield and Bull, 2001 ). Group members share the same home range and overnighting refuges and can stay together for at least five years. Individuals within these groups spend significantly more time interacting with one another than with lizards from neighbouring groups and they are significantly more related to each other than to the rest of the population.
