Resumen en inglés

Dramatic increases in human populations and per capita consumption, climate change, overexploitation of marine and freshwater resources, and deforestation have caused a litany of negative consequences for biodiversity. Such doom-and-gloom scenarios are widely known, frequently cited and frankly depressing. Although accurate assessments of threats have clear value for intervention planning, we believe there is also a need to reflect on successes. Such reflection provides balance to negative scenarios and may shift attention towards constructive, positive action. Here we use a systematic evaluation of 90 success stories provided by conservation scientists and practitioners to explore the characteristics of the projects perceived as being associated with success. Success was deemed to have occurred for 19.4% of the projects simply because an event had occurred (e.g. a law was passed) and for 36.1% of projects quantitative data indicated success (e.g. censuses demonstrated population increase). However, for most projects (63.9%) there was no evaluation and success was defined by the subjective opinion of the respondent. Conservation community members viewed successful projects most often as those being long-term (88%), small in spatial scale (52%), with a relatively low budget (68%), and involving a protectionist approach alone or in combination with another approach. These results highlight the subjectivity of definitions of success in conservation but also the characteristics of conservation efforts that the conservation community perceives as indicative of success.

Resumen en inglés

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.

Forest-dwelling mammals such as primates could be particularly vulnerable to habitat fragmentation; however, the defi nition and quantifi cation of fragmentation have varied considerably among studies. This has resulted in contradictions and thus results are diffi cult to interpret and compare. To encourage a consistent and more precise use of the term “habitat fragmentation,” we reviewed 100 fragmentation studies on primates to quantify how fragmentation effects are assessed. We advocate that habitat fragmentation is a landscape-scale process that involves both loss and the breaking apart of habitat. Hence, independently analyzing both effects is necessary to assess the effects of the breaking apart of habitat while controlling for habitat loss (fragmentation per se). This needs to be done through landscape- scale studies (that is, using landscapes as the independent unit of observation); however, fragmentation studies on primates are typically at the single fragment scale, often with a single continuous forest used for comparison. We suggest that primate responses at the fragment scale can vary dramatically in landscapes with different habitat amounts and confi gurations. In this review we provide clear and consistent terminology to help future studies to accurately assess the effects of fragmentation on primates and to help to form a body of literature where comparisons among studies are possible?.
