This paper report a predation event on Iguana iguana by Boa constrictor recorded in a fluvial island in the Amazonas River, Brazil. Also, provides a list of saurophagy events involving B. constrictor as predator. During a field trip we found an individual of B. constrictor in the process of ingesting a common green iguana (I. iguana), swallowing the headfirst on an upland forest. We found a total of eight lizards as prey of B. constrictor, belonging to three families: Iguanidae, Teiidae and Tropiduridae.

Although males were larger in size and weight, females had higher body condition.

Cuadernos de Herpetología; vol. 32, no. 2 The objective of this research was to make an inventory of the herpetofaunal community of a Caatinga region from Boa Vista’s farm, in Taquaritinga do Norte, Pernambuco state, Brazil. We collected field data from August 2013 to July 2014 using diverse sampling methods: time-limited visual searches, pitfall trapping, record of vestiges and occasional encounters by local people. We could detect the presence of 42 species, 17 amphibians, and 25 reptiles. Rhinella jimi, Tropidurus semitaeniatus and Tropidurus hispidus were apparently the most abundant. The most efficient sampling method was time-limited visual searches, which allowed the record of 34 species. The species composition of the studied community is similar to other Caatinga areas in the state of Pernambuco. We highlight the importance of weirs and similar man-made habitats that provide shelter and reproduction, especially for anurans.; O objetivo deste trabalho foi investigar a comunidade de herpetofauna de uma região da Caatinga na fazenda Boa Vista em Taquaritinga do Norte, Pernambuco. Os dados foram coletados de agosto de 2013 a julho de 2014 usando métodos de amostragem tais quais a busca visual por tempo limitado, armadilhas de pitfall, vestígios e encontros ocasionais pela população local. Através destes quatro métodos foram encontrados e registrados 42 espécies, 17 anfíbios e 25 répteis. Rhinella jimi, Tropidurus semitaeniatus e Tropidurus hispidus foram as espécies com maior abundância e o método mais eficiente foi a busca visual por tempo limitado com um total de 34 espécies registradas. Os dados apresentados sobre a composição são similares a outras áreas da caatinga do estado de Pernambuco, e destacam a importância dos açudes e caldeirões de lajedo para abrigar e promover locais de reprodução para as espécies, principalmente anuros.

In both cases higher prevalences were recorded in cooler seasons, winter and early spring for B. dendrobatidis (0.78 and 0.95 respectively) and autumn for V. rwandae (0.33 and 0.49), with mean temperatures between 11.5 and 17.8°C. No cases of infection were detected in summer. In both cases the probability of infection was strongly influenced by season (and also the year for B. dendrobatidis), but in neither case the occurrence of the other pathogen was significant. The parasitic cycles seem to occur independently and are likely strongly associated to environmental temperatures. Future field studies on amphibian eukaryotic pathogens from temperate areas of South America should consider seasonal variations.; En este trabajo se estudió la prevalencia de dos patógenos cutáneos eucariotas en una población de la rana Boana pulchella (Anura, Hylidae) del sureste de Uruguay, el hongo Batrachochytrium dendrobatidis (Rhizophydiales), y el protista Valentines rwandae (Ichthyosporea, Dermocystida), entre 2012 y 2014. En ambos casos las prevalencias más altas se registraron en épocas frías, invierno y primavera temprana para B. dendrobatidis (0,78 y 0,95 respectivamente) y otoño para V. rwandae (0,33 y 0,49), con temperaturas medias entre 11,5 y 17,8°C. No se detectaron casos de infección en verano. La probabilidad de infección en los dos casos está fuertemente influenciada por la estación (y además por el año para B. dendrobatidis), pero no por la ocurrencia del otro patógeno. Ambos ciclos parasitarios parecen ocurrir independientemente, y son probablemente condicionados en gran medida de la temperatura ambiental. Futuros estudios de campo sobre patógenos eucariotas en anfibios de zonas templadas de Sudamérica deberán tener en cuenta variaciones debidas a la época del año.

This new species of Liolaemus is of medium size (maximum SVL 70.1 mm) and is characterized by presenting a unique color standard in males, where several light-blue scales on the back and side of the body are prominent, and the abdomen is of an intense yellow. Also, the scales of the back and sides of the body are sub-imbricated, with a slight keel and its shape is rounded to triangular. While females, as well as males exhibit pre-cloacal pores. The combination of several states of morphological, morphometric and flake characters and their color standard clearly differentiate these new taxa of the other Liolaemus species, especially of the members of the L. montanus group described for the center and south of Peru. Also, in this study, we present a revision of the taxonomic status and distribution of species of the L. montanus group described or cited for Peru.; Se describe una nueva especie de lagartija del grupo de Liolaemus montanus, endémico de la vertiente occidental de los Andes, en la provincia de Huaytará, departamento de Huancavelica, Perú. Esta nueva especie de Liolaemus, es de tamaño medio (máximo LHC 70,1 mm), se caracteriza por presentar un patrón de coloración único en los machos, donde numerosas escamas celestes se destacan sobre el dorso del cuerpo y el vientre es de color amarillo intenso. Además tiene las escamas del dorso y lados del cuerpo subimbricadas, con quilla leve y de forma redondeada a triangular. Tanto machos como hembras tienen poros precloacales. La combinación de varios estados de caracteres morfológicos, morfométricos, de escamación, y en el patrón de coloración, diferencian claramente este nuevo taxón de las demás especies de Liolaemus, especialmente de los integrantes del grupo de L. montanus descritos para el centro y sur del Perú.
