The majority of amphibian species rely on insects and other invertebrates as their main food source. A decline in the number of insect species available may have devastating impacts on amphibian species worldwide. With 43% of amphibian species experiencing population declines and 32% globally threatened with extinction (AmbhibiaWeb, 2019; Stuart et al., 2004), additional stresses could trigger further declines. Although the effects on amphibian species may vary by location and habitat, species which are specialists on the insects that are in highest decline are most likely to be worst affected. Leer más.

En un esfuerzo por erradicar esta ecotragedia, el Servicio Federal de Pesca y Fauna Silvestre de los Estados Unidos (USFWS) publicó un decreto en enero de 2016 que prohibió que se importaran 201 especies de salamandras a los Estados Unidos en concordancia con la Ley Lacey. Pero ahora algunos científicos, dada la información nueva sobre la propagación del Bsal y sus portadores potenciales, afirman que esta prohibición no es suficiente. Leer más.

An integrative taxonomic analysis using color pattern, morphology, and 1449 base pairs of the ND2 mitochondrial gene and its five flanking tRNAs demonstrated that eight species-level lineages occur within the Cyrtodactylus intermedius complex (Cyrtodactylus intermedius sensu stricto, C. phuquocensis and related populations) of the Cardamom mountains and associated highlands that have a sequence divergence ranging 3.4–8.9%. Additionally, each lineage is discretely diagnosable from one another based on morphology and color pattern and most occur in specific geographic regions (upland areas, karst formations or islands) that prevent or greatly restrict interpopulation gene flow. Six of these lineages were masquerading under the nomen C. intermedius and are described as the following: Cyrtodactylus auralensis sp. nov. endemic to Phnom Aural, the highest mountain in Cambodia; C. bokorensis sp. nov. endemic to the Bokor Plateau, Cambodia; C. cardamomensis sp. nov. from the main block of the Cardamom mountains; C. thylacodactylus sp. nov. endemic to Phnom Dalai the northernmost peak of the Cardamom mountains; C. laangensis sp. nov. endemic to the Phnom Laang karst formation, Cambodia; and C. septimontium sp. nov. from the Bảy Núi Hills of southwest Vietnam.

A finales de enero se conoció que el gobierno colombiano había levantado parcialmente la prohibición para el comercio del caimán aguja* o caretabla (Crocodylus acutus), en el Distrito de Manejo Integrado (DMI) de los manglares de la bahía de Cispatá, Tinajoes, La Balsa y sectores aledaños, en el departamento de Córdoba. La noticia causó gran polémica y generó rechazo en varios sectores que criticaron la medida pues el caimán aguja se encuentra catalogado como Vulnerable en la lista roja de la Unión Internacional para la Conservación de la Naturaleza.
