了解野生动物在空间和时间上面临的威胁对于制定有效的保护策略至关重要。在中美洲（即从墨西哥中部延伸到巴拿马最南端的地区），从20世纪70年代末到21世纪初，至少有40%的两栖动物物种减少。这些下降大多与两栖动物适宜栖息地的破坏以及真菌病原体壶菌的引入和传播有关，壶菌病是这种疾病的病因。在这项研究中，我们量化了中美洲直接发育的河流栖息蛙种（DSFS）的地理和海拔范围。在每个DSFS范围内，我们估计了适合树突壶菌发生的面积范围和土地利用类型，以量化栖息地恶化。自2005年或之前至今，33%的DSFS未被发现。在区域层面（如中美洲），与之前的研究一样，我们发现狭窄的地理和海拔范围增加了物种灭绝的脆弱性。然而，在20世纪80年代至2005年期间，83%的DSFS范围由50%或更多的优质栖息地组成，当时大多数物种减少。我们还发现，平均而言，每个物种目前的范围有80%与预测的适合出现的区域重叠。在局地和立地水平上（即对两个物种范围进行了广泛的监测，甚至在下降之前就已经进行了监测），我们发现目前的适宜栖息地与DSFS预测的栖息地适宜性和气候生态位的降低不一致。我们还发现，残种群的位置可以通过环境因子来预测，这有助于确定这些退化物种和其他生态相似的物种可能出现的残种群区域。综合我们的区域和本地分析结果，支持了batrachochytrium dendroatidiss是DSFS下降的主要驱动因素，以及目前缺乏15个DSFS最近观察的观点。我们利用我们的结果提出了针对本研究中所有DSFS的具体措施。该研究强调了在评估濒危物种状况时考虑多种威胁和空间尺度的重要性。
Understanding the threats to wildlife across space and time is essential for developing effective conservation strategies. In Mesoamerica (i.e., the region that extends from Central Mexico to the most southern point in Panama) at least 40% of amphibian species declined between the late 1970s and the early 2000s. Most of these declines have been linked with the destruction of suitable habitats for amphibians as well as the introduction and spread of the fungal pathogenBatrachochytrium dendrobatidis, the causal agent of the disease known as chytridiomycosis. In this study, we quantified geographic and elevational ranges for direct-developing, stream-dwelling frog species (DSFS) in Mesoamerica. Within the range of each DSFS, we estimated the extent of suitable area for the occurrence ofBatrachochytrium dendrobatidisand the types of land use to quantify habitat deterioration. To date, 33% of DSFS remain undetected since 2005 or before. At the regional level (i.e., Mesoamerica), as in previous studies, we found that narrow geographic and elevational ranges increased vulnerability to extinction. Nevertheless, the ranges of 83% of DSFS were composed of 50% or more high-quality habitats between the 1980s and 2005, when most species declined. We also found that on average, 80% of the range of each species currently overlaps with predicted suitable areas for the occurrence ofBatrachochytrium dendrobatidis. At the local and site level (i.e., focusing on two species ranges where extensive monitoring has been conducted even before decline occurred), we found that the present suitable habitat forBatrachochytrium dendrobatidiscorresponded with the reduction in predicted habitat suitability and climatic niche of DSFS. We also found that the location of remnant populations can be predicted by environmental factors, which can help identify regions where remnant populations of these declined species and others with similar ecology may occur. Combined, results from our regional and local analyses support the idea thatBatrachochytrium dendrobatidiswas the main driver of DSFS declines and of the current lack of recent observations of fifteen DSFS. We used our results to propose specific actions for all DSFS included in this study. This study highlights the importance of considering multiple threats and spatial scales when assessing the status of declined and threatened species.
