Lunaschi, and Fabiana B. Drago Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, División Zoología Invertebrados, Museo de La Plata, Paseo del Bosque S/Nº, 1900 La Plata, Buenos Aires, Argentina Received 30 May 2013; accepted 15 October 2014 Abstract Two species of nematodes, Rhabdias cf. elegans (Rhabdiasidae) and Aplectana hylambatis (Cosmocercidae), were recovered from the lungs and intestine of Trachycephalus typhonius (Anura: Hylidae) captured in Formosa Province, Argentina. Morphological and morphometric data of both species are provided, and previous records of Rhabdias spp. in the Neotropical region are summarized. The finding of Rhabdias cf. elegans constitutes the first record of this genus in the Formosa Province, and the finding of A. hylambatis represents the first record of this species as a parasite of hylid frogs, and the first report in Formosa Province. Trachycephalus typhonius represents a new host for both parasites. All Rights Reserved © 2015 Universidad Nacional Autónoma de México, Instituto de Biología.

Accepted 11 May, 2011 In captivity some anurans can show poor growth and skeletal development due to inadequate levels of UV-B radiation. From metamorphosis for 84 days the growth and skeletal development of Amazonian milk frogs (Trachycephalus resinifictrix ) were assessed between treatments receiving daily UV-B (UV/daily), intense UV-B for 30 min every two weeks (UV/boost), or no UV-B (control). At 14 day intervals snout-urostyle length, weight, and X-ray images were taken. At day 84 five morphometric skeletal variables were measured and compared for absolute values and isometry. At day 42 and 84, X-ray images were compared for maximum opacity. At day 84 the UV/daily treatment showed greater snout- urostyle length, weight, condition index, vertebrae length, head width, and femur length than the other two treatments. The head width:snout-urostyle length ratio was greater in the control than in the UV/daily treatment. Calcification did not vary between treatments at day 84. Skeletal development in the control showed symmorphic growth of increased head width: head length ratio.

  • Diet of Rhinella Arenarum (Anura, Bufonidae) in a Coastal Habitat in Southern Brazil
    Herpetology Notes, volume 10: 507-510 (2017) (published online on 14 September 2017) Diet of Rhinella arenarum (Anura, Bufonidae) in a coastal habitat in southern Brazil Mateus de Oliveira1,*, Fernanda R. de Avila1 and Alexandro M. Tozetti1 Abstract. Amphibians are good models for the study of trophic ecology because they occupy different trophic levels during their development. In this study, we evaluated the diet of Rhinella arenarum (Hensel, 1867) during breeding season in a marine–freshwater transitional habitat in southern Brazil. Based on the analysis of stomach contents, we recorded five groups of invertebrates (Araneae, Coleoptera, Diptera, Hymenoptera and Orthoptera). Despite of their low palatability, Coleoptera was the most representative group by both numeric and volumetric evaluation. The studied population had a smaller number of items in their diet when compared with to previous studies. These results suggest an example of a specialization in the diet during R. arenarum at this habitat, being Coleoptera the most common prey. Keywords: Behaviour, diet composition, sand dunes Amphibians are good models for the study of trophic species throughout its distribution area, which extends ecology because they occupy different trophic levels of from the coastal region of southern Brazil to Uruguay, food webs (Duré et al., 2009).

Gabriela Perotti y Mónica M. Steciow, porque sin subirme a sus hombros confiados, confiables, seguros… no hubiera podido llegar hasta acá. Por confiar en mi a la distancia sin prejuicios y dejar que me quede en casa. A Gaby, por su incondicional presencia y apoyo, su manera clara y directa de hacerme ver las cosas y su sinceridad. Por hacerme fácil el trabajo en todo momento en base a su paciencia infinita y su seguridad plena. ¡Gracias Gigante! A Moni, por su inquebrantable empuje y entusiasmo,

  • Amphibian Conservation in the Caatinga Biome and Semiarid Region of Brazil

In this study, we searched for ‘‘hot spots’’ of amphibians in these two regions and assessed whether the priority areas established by the MMA coincided with those suitable for amphibian conservation. We determined amphibian hot spots by means of three estimates: areas of endemism, areas of high species richness, and areas with species that are threatened, rare, or have very limited distributions. We then assessed the degree of coincidence between amphibian hot spots and the priority areas of the MMA based on the current conservation units. We analyzed areas of endemism with the use of a parsimony analysis of endemicity (PAE) on quadrats. The Caatinga biome and semiarid region showed four and six areas of endemism, respectively, mainly associated with mountainous areas that are covered by isolated forests and positively correlated with species richness.
