Abstract

The salamander Dendrotriton megarhinus (Rabb, 1960) (Caudata, Plethodontidae), previously known only from Cerro Tres Picos in La Sepultura Biosphere Reserve, Chiapas, Mexico, has been found at Cerro La Bola, Chiapas, extending its geographic range. In this report we provide four new records and outline aspects of the species' ecology as well as threats to its habitat. Despite conservation efforts, the species remains Vulnerable to threats like climate change and infectious disease. We emphasize the impor-tance of its conservation and the continued monitoring of the species and its habitat. [ABSTRACT FROM AUTHOR]

Abstract

Effective and targeted conservation action requires detailed information about species, their distribution, systematics and ecology as well as the distribution of threat processes which affect them. Knowledge of reptilian diversity remains surprisingly disparate, and innovative means of gaining rapid insight into the status of reptiles are needed in order to highlight urgent conservation cases and inform environmental policy with appropriate biodiversity information in a timely manner. We present the first ever global analysis of extinction risk in reptiles, based on a random representative sample of 1500 species (16% of all currently known species). To our knowledge, our results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles. Nearly one in five reptilian species are threatened with extinction, with another one in five species classed as Data Deficient. The proportion of threatened reptile species is highest in freshwater environments, tropical regions and on oceanic islands, while data deficiency was highest in tropical areas, such as Central Africa and Southeast Asia, and among fossorial reptiles. Our results emphasise the need for research attention to be focussed on tropical areas which are experiencing the most dramatic rates of habitat loss, on fossorial reptiles for which there is a chronic lack of data, and on certain taxa such as snakes for which extinction risk may currently be underestimated due to lack of population information. Conservation actions specifically need to mitigate the effects of human-induced habitat loss and harvesting, which are the predominant threats to reptiles.

Abstract

Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.

13. Abundancia, uso de hábitat, microhábitat y hora de actividad de Ameiva undulata(Squamata: Teidae) en un paisaje fragmentado del Soconusco chiapaneco

Author

Abstract

La transformación de los ambientes naturales hacia ambientes manejados como cultivos o pastizales conlleva un impacto directo en la abundancia de las especies que ahí habitan. Se ha registrado que algunos cultivos, como los cafetales de sombra diversificada tienen un menor efecto en la abundancia de las especies y que incluso pueden incrementar su abundancia. En un mosaico de cafetales diversificados y bosques nativos en el Soconusco chiapaneco, se evaluó la abundancia por mes, utilización del hábitat, microhábitat y hora de actividad en la lagartija Ameiva undulataen, durante noviembre del 2000 a abril del 2002. La abundancia más alta fue registrada en febrero. La mayoría de organismos se observó en cafetales de sombra diversificada y en microhábitats asociados a la hojarasca. A lo largo del día, la mayor actividad se registró de las ll:00 a 12:00h, seguida por un decremento continuo en el nivel de actividad hasta las 18:00h. Los resultados indican que esta lagartija presenta una mayor abundancia en ambientes con insolación y perturbación media, condiciones que están poco representadas en ambientes conservados como los bosques mesófilos y las selvas medianas, o bien, en ambientes altamente transformados y sin sombra como los pastizales.

Abstract

Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.
