Nematode Parasites of Lizards (Squamata, Sauria) from the Cerrado Biome in the State of Minas Gerais, Brazil Herpetology Notes, volume 12: 855-863 (2019) (published online on 12 August 2019) Nematode parasites of lizards (Squamata, Sauria) from the Cerrado biome in the State of Minas Gerais, Brazil Fabiano M. Vieira1,*, Thais T. Souza2, Iara A. Novelli2, Sueli de Souza Lima3, Luís C. Muniz-Pereira1, and Bernadete M. Sousa2 Abstract. The current study registered the nematode infections in 10 lizard species for a not studied locality in the Cerrado biome in the state of Minas Gerais, Brazil. A total of 101 hosts were analysed, of these 24 were parasitized by at least one species of nematode. We observed a total richness of 10 species of nematodes, and the lizard species with the most records of nematode species were Aspronema dorsivitattum and Ophiodes striatus, with a total of three species each. In addition, seven new host records (NHR) and nine new geographical records (NGR) were recorded in the respective lizard species of the Cerrado biome in state of Minas Gerais, Brazil. Keywords.

  • Some Aspects of the Taxonomy and Biology of Adult Spirurine Nematodes Parasitic in Fishes: a Review
    FOLIA PARASITOLOGICA 54: 239–257, 2007 REVIEW ARTICLE Some aspects of the taxonomy and biology of adult spirurine nematodes parasitic in fishes: a review František Moravec Institute of Parasitology, Biology Centre, Academy of Sciences of the Czech Republic, Branišovská 31, 370 05 České Budějovice, Czech Republic Key words: Nematoda, Spirurina, Cystidicolidae, Rhabdochonidae, parasites, fish, taxonomy, biology Abstract. About 300 species belonging to four superfamilies (Gnathostomatoidea, Habronematoidea, Physalopteroidea and Thelazioidea) of the nematode suborder Spirurina are known as the adult parasites of freshwater, brackish-water and marine fishes. They are placed in four families, of which the Gnathostomatidae, including Echinocephalus with a few species and the monotypic Metaleptus, are parasites of elasmobranchs, whereas Ancyracanthus contains one species in teleosts; the Physalopteri- dae is represented in fish by four genera, Bulbocephalus, Heliconema, Paraleptus and Proleptus, each with several species in both elasmobranchs and teleosts. The majority of fish spirurines belongs to the Rhabdochonidae, which includes 10 genera (Beaninema, Fellicola, Hepatinema, Heptochona, Johnstonmawsonia, Megachona, Pancreatonema, Prosungulonema, Rhabdo- chona and Vasorhabdochona) of species parasitizing mainly teleosts, rarely elasmobranchs, and the Cystidicolidae with about 23 genera (Ascarophis, Caballeronema, Capillospirura, Comephoronema, Crenatobronema, Cristitectus, Ctenascarophis, Cyclo- zone, Cystidicola, Cystidicoloides, Johnstonmawsonoides,

    SCALE-DEPENDENT VARIATION IN MOLECULAR AND ECOLOGICAL PATTERNS OF INFECTION FOR ENDOHELMINTHS FROM CENTRARCHID FISHES BY KYLE E. LUTH A Dissertation Submitted to the Graduate Faculty of WAKE FOREST UNIVERSITY GRADAUTE SCHOOL OF ARTS AND SCIENCES in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY Biology May 2016 Winston-Salem, North Carolina Approved By: Gerald W. Esch, Ph.D., Advisor Michael V. K. Sukhdeo, Ph.D., Chair T. Michael Anderson, Ph.D. Herman E. Eure, Ph.D. Erik C. Johnson, Ph.D. Clifford W. Zeyl, Ph.D. ACKNOWLEDGEMENTS First and foremost, I would like to thank my PI, Dr. Gerald Esch, for all of the insight, all of the discussions, all of the critiques (not criticisms) of my works, and for the rides to campus when the North Carolina weather decided to drop rain on my stubborn head. The numerous lively debates, exchanges of ideas, voicing of opinions (whether solicited or not), and unerring support, even in the face of my somewhat atypical balance of service work and dissertation work, will not soon be forgotten. I would also like to acknowledge and thank the former Master, and now Doctor, Michael Zimmermann; friend, lab mate, and collecting trip shotgun rider extraordinaire. Although his need of SPF 100 sunscreen often put our collecting trips over budget, I could not have asked for a more enjoyable, easy-going, and hard-working person to spend nearly 2 months and 25,000 miles of fishing filled days and raccoon, gnat, and entrail-filled nights. You are a welcome camping guest any time, especially if you do as good of a job attracting scorpions and ants to yourself (and away from me) as you did on our trips.

  • 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.

  • Copeoglossum Aurae (Greater Windward Skink) Family: Scincidae (Skinks) Order: Squamata (Lizards and Snakes) Class: Reptilia (Reptiles)
    UWI The Online Guide to the Animals of Trinidad and Tobago Diversity Copeoglossum aurae (Greater Windward Skink) Family: Scincidae (Skinks) Order: Squamata (Lizards and Snakes) Class: Reptilia (Reptiles) Fig. 1. Greater windward skink, Copeoglossum aurae. [http://www.trinidad-tobagoherps.org/Mabuyanigropunctata.htm, downloaded 16 October 2016] TRAITS. Copeoglossum aurae is a newly discovered skink in Trinidad and Tobago (Hedges and Conn, 2012). It has a dark lateral solid stripe that extends from under its oval shaped ear past its hind legs onto the tail (Fig. 1). C. aurae male and female specimens can reach a maximum of 98.5mm and 109mm snout-vent length, respectively, and tails can reach up to 65mm. They are heavily scaled lizards with scales being smaller on the limbs in comparison to other body parts. Their tails, like some other reptiles, can be broken off and regenerated. The dorsal colour of most specimens are greyish-green with small to medium deep brown spots evenly spread on the body, limbs and tail. The dorsal colours are different shades of brown, grey and green, and green-white lateral stripes are found from the ear to the hind limbs (Hedges and Conn, 2012). DISTRIBUTION. Copeoglossum aurae species is distributed in some islands of the Caribbean including southern Windward Islands like St. Vincent and the Grenadines, Grenada, Trinidad and Tobago, and it was postulated that some may have migrated to parts of South America (Venezuela) (Murphy et al., 2013). HABITAT AND ECOLOGY. C. aurae exhibit both arboreal and non-arboreal characteristics, since they are found either on trees or on the ground (Murphy et al., 2013).

    Volume 27 (April 2017), 201–216 Herpetological Journal FULL PAPER Published by the British Predation of Jamaican rock iguana Cyclura( collei) nests Herpetological Society by the invasive small Asian mongoose (Herpestes auropunctatus) and the conservation value of predator control Rick van Veen & Byron S. Wilson Department of Life Sciences, University of the West Indies, Mona 7, Kingston, Jamaica The introduced small Asian mongoose (Herpestes auropunctatus) has been widely implicated in extirpations and extinctions of island taxa. Recent studies and anecdotal observations suggest that the nests of terrestrial island species are particularly vulnerable to mongoose predation, yet quantitative data have remained scarce, even for species long assumed to be at risk from the mongoose. We monitored nests of the Critically Endangered Jamaican Rock Iguana (Cyclura collei) to determine nest fate, and augmented these observations with motion-activated camera trap images to document the predatory behaviour of the mongoose. Our data provide direct, quantitative evidence of high nest predation pressure attributable to the mongoose, and together with reported high rates of predation on hatchling and juvenile iguanas (also by the mongoose), support the original conclusion that the mongoose was responsible for the apparent lack of recruitment and the aging structure of the small population that was ‘re-discovered’ in 1990. Encouragingly however, our data also demonstrate a significant reduction in nest predation pressure within an experimental mongoose-removal area. Thus, our results indicate that otherwise catastrophic levels of nest loss (at or near 100%) can be ameliorated or even eliminated by removal trapping of the mongoose. We suggest that such targeted control efforts could also prove useful in safeguarding other threatened insular species with reproductive strategies that are notably vulnerable to mongoose predation (e.g., the incubation of eggs on or underground).

Anguillicoloides crassus is of particular importance, as it has recently spread from its endemic range in the Eastern Pacific to Europe and North America, where it poses a significant threat to new, naïve hosts such as the economic important eel species Anguilla anguilla and Anguilla rostrata. The Anguillicolidae are therefore all potentially invasive taxa, but the relationships of the described species remain unclear. Anguillicolidae is part of Spirurina, a diverse clade made up of only animal parasites, but placement of the family within Spirurina is based on limited data.

Sanchiz (*) RESUMEN Durante el periodo 1978-1994 se han descrito cerca de 2.000 especies animales nue- vas para la ciencia en territorio ibérico-balear. Se presenta como apéndice un listado completo de las especies (1978-1993), ordenadas taxonómicamente, así como de sus referencias bibliográficas. Como tendencias generales en este proceso de inventario de la biodiversidad se aprecia un incremento moderado y sostenido en el número de taxones descritos, junto a una cada vez mayor contribución de los autores españoles. Es cada vez mayor el número de especies publicadas en revistas que aparecen en el Science Citation Index, así como el uso del idioma inglés. La mayoría de los phyla, clases u órdenes mues- tran gran variación en la cantidad de especies descritas cada año, dado el pequeño núme- ro absoluto de publicaciones. Los insectos son claramente el colectivo más estudiado, pero se aprecia una disminución en su importancia relativa, asociada al incremento de estudios en grupos poco conocidos como los nematodos.
