“…The Sahamalaza–Iles Radama National Park is located within the Sambirano domain of Madagascar, a transitional area between the rainforests of the north and the drier deciduous forests of the west (Project ZICOMA 1999). Sahamalaza has a hot and subhumid climate (Andreone et al 2001) with a wet season from November until April followed by a dry season from May until October. Temperatures fluctuate around 28.0 °C throughout the year, with a maximum mean temperature of 32.0 °C, minimum mean temperature of 20.6 °C, and an extreme temperature range of 13.2 °C–39.1 °C (Schwitzer et al 2007; Volampeno et al 2011).…”

Primates require secure sleeping sites for periods of rest, but despite their importance, the characteristics of desired sleeping sites are poorly known. Here we investigated the sleeping ecology of a radio-collared population of the Sambirano mouse lemur, Microcebus sambiranensis, during the nonreproductive season in the Anabohazo forest, northwestern Madagascar. We also investigated their ranging behavior and examined the spatial distribution of sleeping sites within the home ranges of the collared individuals. We took measurements of the sleeping tree’s physical characteristics and recorded the number of collared individuals using each sleeping site. We found that M. sambiranensis generally use foliage sleeping sites more frequently than tree holes and individuals slept more frequently in densely foliated trees than in sparsely foliated trees, often alone. We observed no significant differences in home range size or nightly travel distance between males and females; however, home ranges were smaller than those described for other mouse lemur species. Finally, we found that M. sambiranensis sleep peripherally and forage centrally within their home ranges, a behavior not previously described for mouse lemurs. Our results indicate profound differences in the social organization between M. sambiranensis and other mouse lemur species described in the literature, suggesting species-specificity in mouse lemur ecology. Understanding the sleeping ecology and ranging behavior of mouse lemurs is of great importance to their conservation, as these data facilitate the planning of long-term reforestation, habitat management, and population assessment.

The Strict Nature Reserve of Betampona protects one of the last remaining relicts (about 2,228 ha) of low elevation rainforests in eastern Madagascar. Yet little has been previously published about the amphibian fauna of this rainforest. During 2004 and 2007, Betampona was surveyed over a total period of 102 days. Frogs were searched by opportunistic searching, pitfall trapping and acoustic surveys. The survey work confirmed the occurrence of 76 taxa, of which 36 are currently candidate species and about 30% were first considered as undescribed species. The identification of species included a multidimensional and integrative approach that links morphology, bioacoustics, ecology and Electronic supplementary material The online version of this article (genetics. Of these taxa, 24 species are potentially endemic to this low elevation eastern region. Considering the relatively small area of the Betampona forest, and its narrow elevational range, 76 amphibian species represents an unusually high richness compared to other sites in Madagascar. Although the eastern region is now largely deforested, our results reveal the importance of this relict forest, which is protecting a diverse amphibian fauna that includes many potentially endemic species.

“…Se encontraron fluctuaciones temporales en la estructura de la comunidad (riqueza, abundancia, diversidad y equitatividad), con cambios más marcados para los anfibios que en reptiles, existiendo un recambio estacional de especies, en especial de anfibios, como es sugerido en estudios previos en diversos hábitats (e.g. Abe 1995, Androne et al 2001, García 2003. Lo anterior es notorio al observar que las tendencias temporales registradas en reptiles y anfibios fueron en cierta manera opuesta, la mayor riqueza y abundancia de reptiles durante las secas y la de anfibios durante las lluvias.…”

“…Las diferencias en las tendencias temporales en la riqueza, abundancia y diversidad de los reptiles y anfibios en la región de Chamela y otros ambientes estacionales pueden deberse, en parte, a la contrastante fisiología de estos grupos haciendo que la ocurrencia de sus especies, sus niveles y tipos de actividad difiera por los efectos de la estacionalidad ambiental (Baker 1990, McComb et al 1993a& b, Gómez & Anthony 1996, Androne et al 2001. Así, en esta comunidad existe baja presencia general de anfibios durante la época de secas y una presencia más o menos constante de reptiles a lo largo del año, el 22% de las especies de anfibios se registraron en ambas épocas contrastando con el 40% registrado en reptiles.…”

RESUMENSe evaluó el efecto de la estacionalidad ambiental y la estructura de la vegetación en los patrones espacio-temporales de la comunidad (composición, diversidad, riqueza y abundancia relativa) de los anfibios y reptiles de la región de Chamela, Jalisco. Tres sitios fueron muestreados, mediante un diseño de bloque dentro de una matriz de vegetación de arroyo (VA) y bosque tropical caducifolio (BTC) utilizando tres técnicas complementarias de muestreo (trampeo; parcelas de búsqueda intensiva y transectos visuales) durante la época de secas y de lluvias. Se registraron 34 especies (25 de reptiles y nueve de anfibios). Las curvas de acumulación de especies y los índices predictores de riqueza, sugieren que el esfuerzo de muestreo fue el adecuado. Los valores más altos de riqueza, diversidad y abundancia se registraron en la VA. Se registraron mayores fluctuaciones estacionales en anfibios que en reptiles, y en el BTC que en la VA. Se documenta un recambio de especies, tanto espacial (matriz de vegetación VA-BTC) como temporal (estacional), más marcado en anfibios cuyo registro de individuos fue mínimo durante la época de secas y solo dentro de la VA. La VA es importante para el mantenimiento de la diversidad herpetofaunística, no sólo por su menor estacionalidad y mayor productividad, sino por su mayor complejidad estructural. Se encontró una mayor respuesta de los anfibios hacia los cambios en la estructura de la vegetación que los reptiles, los cuales estuvieron más ampliamente distribuidos espacial y temporalmente. Palabras clave: bosque tropical caducifolio; herpetofauna; estacionalidad ambiental; vegetación; estructura de la comunidad ABSTRACT The effect of effect of environmental seasonality and habitat structure on the spatial and temporal patterns of the reptile and amphibian communities in Chamela, Jalisco, Mexico was evaluated. Three complementary sampling techniques (plots, visual transects and sampling arrays with drift fences and pitfall traps) were used in three sites during the wet and dry seasons using a block design to sample the seasonally dry tropical forest (SDTF) and its adjacent arroyo forest (VA). Thirty-four species were recorded (25 of reptiles and 9 of amphibians). The species accumulation curves and richness predictors suggested sampling effort was appropriated. Highest values of species richness, diversity and relative abundance were recorded in the VA when compared with the SDTF. Seasonal fluctuations were marker in the amphibian community and in the SDTF than in reptiles and the VA respectively. There is a marked species turn over both spatially (along the VA and SDTF) and temporally (across the seasons) more Acta Zoológica Mexicana (n.s.) 24(2): 91-115 (2008) especially evident in amphibians. Arroyo forest is important for the maintenance of species diversity, especially for amphibians, because in this vegetation environmental seasonality is less marked, and both productivity and vegetation structure is higher. The response of amphibians to changes in vegetation structure wa...
