“…Sin embargo, será necesario realizar análisis de distribución con estos datos mediante modelos predictivos, que nos permitan obtener mayor información. El nodo Centro de México se encuentra ubicado en una zona donde ya se han realizado algunos estudios para establecer prioridades de conservación de los mamíferos (Fuller et al 2006), donde de manera indirecta, también se propone conservar su helmintofauna.…”

. 2011. Análisis panbiogeográfico de Vexillata (Nematoda: Ornithostrongylidae) y sus huéspedes (Mammalia: Rodentia). Acta Zool. Mex. (n. s.), 27(1): 25-46. RESUMEN. Se llevó a cabo un análisis panbiogeográfico, a partir de un análisis de parsimonia de endemismos (PAE) de las especies de helmintos parásitos intestinales del género Vexillata (Nematoda: Ornithostrongylidae) y sus especies de huéspedes, mamíferos de las familias Geomyidae y Heteromyidae. Se realizaron dos análisis, el primero empleando solo aquellas especies del género Vexillata con más de dos localidades, y el segundo, analizando todas las localidades de este género de parásito en un solo trazo individual. Se obtuvieron tres trazos generalizados a partir del PAE del primer análisis: costa norte de Venezuela, América Central y Neártico. Solo uno de los trazos fue sustentado por una especie de parásito y su huésped (V. tejerai y Heteromys anomalus). Se propone la existencia de un nodo biogeográfico en Colombia, entre el trazo de la costa norte de Venezuela y el de América Central en el noroeste de Colombia, en los límites con Panamá; y otro en la zona central de México. Estos trazos y nodos coinciden con algunos propuestos por otros autores. En general se observa que estos sistemas pueden ser explicados como tres componentes bióticos. En particular el de América del Sur puede corresponder con aquellas que especiaron por aislamiento (V. scorzai), y especies con distribuciones amplias (V. tejerai), quizá más relacionadas a etapas de movilidad de sus huéspedes (Heteromys). Palabras clave: helmintos parásitos, nemátodos, mamíferos, panbiogeografía, provincias biogeográ-ficas.

“…It works as an effective tool that should be applied in systematic conservation planning to identify and interconnect priority regions, particularly those already covered by natural protected areas [69]. Moreover, it is an efficient tool for identifying gaps in actual reserve systems, especially when it highlights regions that surround protected areas and, therefore, complement proposed conservation plans [69][70][71]. Although amphibians and reptiles are not commonly used as biodiversity surrogates in systematic conservation planning [22], recently, niche-based distribution models combined with reserve selection techniques were used to pinpoint conservation priorities in India [22] and Mexico [72].…”

Tropical amphibians face a severe decline crisis with ca. 35% of species being currently threatened in the Neotropics. We selected 16 endangered-hylid species and used species records to model their potential geographical distribution for the continental Neotropics. We found that there is a strong influence of slope in hylid geographical distribution that interacts synergistically with maximum rainfall and temperature changes over the year. We identified some intersecting areas of species overprediction along southern Neotropics, which could be important for future biological surveys searching for undescribed microendemic hylid species. Nine of the 16 studied hylids have small geographic ranges with only 25% of its potential distribution being currently protected in the Neotropics. The remaining seven species are still in need of additional conservation areas to ensure the protection of at least 25% of its original distribution range in Mesoamerica. Most Neotropical endangered hylids have only the periphery of their distribution protected with its core distribution outside protected areas. These species may be especially threatened because they now occur in small, isolated subpopulations due to habitat fragmentation and loss. We suggest that conservation efforts for Neotropical hylids should be focused on restricted-range species and in the establishment of additional conservation area networks in Mesoamerica. Remaining habitats for threatened hylids need to be managed as a coordinate network including sitescale and landscape-scale actions to buffer the extinction-driven process caused by inbreeding, genetic drift, and demographic stochasticity.Keywords: Endangered species, conservation biogeography, tree frogs, MaxEnt, protected areas, habitat fragmentation. ResumenEn la actualidad, los anfibios tropicales enfrentan una crisis muy severa con un 35% de especies en peligro de extinción en el Neotrópico. Se seleccionaron 16 hílidos en peligro de extinción y se usaron registros de especies para modelar su distribución geográfica potencial a lo largo del neotrópico continental. Se encontró que hay una fuerte influencia de la pendiente topográfica en la distribución potencial de los hílidos que interactúa sinérgicamente con la precipitación máxima y los cambios de temperatura a lo largo del año. Se identificaron algunas áreas de sobrepredicción de especies a lo largo del sur del neotrópico con gran potencial para direccionar futuras expediciones biológicas en busca de nuevas especies microendémicas de hílidos. Nueve de las 16 especies de hílidos estudiadas presentaron rangos geográficos muy restringidos presentando solo el 25% de su distribución geográfica potencial dentro de áreas naturales protegidas en el Neotrópico. Las otras siete especies requieren la implementación de nuevas áreas de conservación que aseguren la protección de por lo menos el 25% de su rango de distribución original en Mesoamérica. Algunos de los hílidos amenazados presentan solo su periferia conservada con su núcleo de distribución fue...

“…Nandini et al (2009) recommended forest corridors connecting disturbed habitat as an important con servation measure. Fuller et al (2006) suggested the need for effective conservation plans which take into account both the need for protected area connectivity and the requirements of the local human population (Gillingham & Lee 1999), possibly through multi-criteria analysis (Moffett & Sarkar 2006) and ecological niche modeling (Thorn et al 2009). It is necessary to raise awareness among the tribal people of Arunachal Pradesh for wildlife species, particularly for primate species such as the slow loris, which act as seed dispersal agents and which prey on several forest insect species (biological control).…”

The present study provides data collected during rescue operations involving Bengal slow loris Nycticebus bengalensis which were carried out opportunistically in and around Itanagar Wildlife Sanctuary, Arunachal Pradesh, India. A total of 27 individuals consisting of 21 males and 6 females were rescued from the study sites; 81% of these were adult and 19% sub-adult. Of the 27 individuals, 12 were rescued from private gardens. All rescued individuals were kept under observation in the Biological Park zoo situated within the sanctuary, where they received the necessary treatment, and were then released to the wild in the sanctuary. Various anthropogenic threats were recorded in the study; these included illegal logging, firewood collection, forest fires and habitat encroachment to enable the traditional practice of shifting cultivation, and infrastructural developmental activities. The present study highlights factors impeding the conservation of slow loris in and around the sanctuary. FREE REE
