  • 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.

Conclusions Acknowledgments Glossary Bibliography Biographical Sketch Summary The main features that differentiate “reptiles” from amphibians are their dry scaled tegument andUNESCO their shelled amniotic eggs. In– modern EOLSS studies, birds are classified under the higher category named “Reptilia”, but the term “reptiles” used here does not include birds. One can externally identify at least, three groups of reptiles: turtles, crocodiles, and lizards and snakes. However, all of these three groups are made up by many species that are differentSAMPLE in some morphological characters CHAPTERS like number of scales, color, size, presence or absence of limbs. Also, the habitat use is quite variable; there are reptiles living in almost all the habitats of the Earth, but the majority of the species are only found in the tropical regions of the world. The West Indies is a region of special interest because of its tropical climate, the high number of species living on the islands, the high level of endemism, the high population densities of many species, and the recognized adaptive radiation that has occurred there in some genera, such as Anolis, Sphaerodactylus, and Tropidophis.

This neglect has hindered our understanding of the evolution of venom by causing us to ignore the interactions which shape this evolution, interactions that take place between venomous snakes and their prey and predators, as well as among conspecific venomous snakes within populations.
