Abstract

Climate change is one of the major drivers of biodiversity loss. Among vertebrates, amphibians are one of the more sensitive groups to climate change due to their unique ecology, habitat requirements, narrow thermal tolerance and relatively limited dispersal abilities. We projected the influence of climate change on an endemic toad, Malabar Tree Toad (Pedostibes tuberculosus; hereafter MTT) from the Western Ghats biodiversity hotspot, India, for two different shared socio-economic pathways (SSP) using multiple modeling approaches for current and future (2061-2080) scenarios. The data used predominantly comes from a citizen science program, 'Mapping Malabar Tree Toad' which is a part of the Frog Watch citizen science program, India Biodiversity Portal. We also evaluated the availability of suitable habitats for the MTT in Protected Areas (PAs) under the current and future scenarios. Our results show that annual precipitation was the most important bioclimatic variable influencing the distribution of MTT. We used MaxEnt (MEM) and Ensemble (ESM) modeling algorithms. The predicted distribution of MTT with selected environmental layers using MEM was 4556.95 km while using ESM was 18,563.76 km. Overlaying PA boundaries on predicted distribution showed 37 PAs with 32.7% (1491.37 km) and 44 PAs with 21.9% (4066.25 km) coverage for MEM and ESM respectively. Among eight future climate scenarios, scenarios with high emissions showed a decreased distribution range from 33.5 to 68.7% of predicted distribution in PAs, while scenarios with low emissions showed an increased distribution range from 1.9 to 111.3% in PAs. PAs from the Central Western Ghats lose most suitable areas with a shift of suitable habitats towards the Southern Western Ghats. This suggests that MTT distribution may be restricted in the future and existing PAs may not be sufficient to conserve their habitats. Restricted and discontinuous distribution along with climate change can limit the dispersal and persistence of MTT populations, thus enhanced surveys of MTT habitats within and outside the PAs of the Western Ghats are an important step in safeguarding the persistence of MTT populations. Overall, our results demonstrate the use of citizen science data and its potential in modeling and understanding the geographic distribution and the calling phenology of an elusive, arboreal, and endemic amphibian species.

摘要

气候变化是生物多样性丧失的主要驱动因素之一。在脊椎动物中,由于其独特的生态、生境需求、狭窄的热耐受能力和相对有限的扩散能力,两栖动物对气候变化更为敏感。我们使用多种建模方法,对来自印度西高止山脉生物多样性热点地区的特有蟾蜍——马拉巴尔树蟾(Malabar Tree Toad, Pedostibes tuberculosus),预测了在两种不同的共享社会经济路径(SSP)下,当前和未来(2061-2080 年)情景下气候变化的影响。所使用的数据主要来自公民科学项目“马拉巴尔树蟾地图绘制”(Mapping Malabar Tree Toad),该项目是印度生物多样性门户下的青蛙观察公民科学项目的一部分。我们还评估了在当前和未来情景下,保护地(PA)内马拉巴尔树蟾适宜栖息地的可用性。我们的结果表明,年降水量是影响马拉巴尔树蟾分布的最重要的生物气候变量。我们使用了最大熵(MaxEnt,MEM)和集成(Ensemble,ESM)建模算法。使用 MEM 选择环境层预测马拉巴尔树蟾的分布,结果为 4556.95 公里,而使用 ESM 则为 18563.76 公里。将保护地边界叠加在预测分布上,MEM 覆盖了 37 个保护地,占 32.7%(1491.37 公里),ESM 覆盖了 44 个保护地,占 21.9%(4066.25 公里)。在八个未来气候情景中,高排放情景下的分布范围从保护地预测分布的 33.5%到 68.7%减少,而低排放情景下的分布范围从保护地预测分布的 1.9%到 111.3%增加。西高止山脉中部的保护地失去了最适宜的区域,适宜栖息地向西高止山脉南部转移。这表明马拉巴尔树蟾的分布可能在未来受到限制,现有的保护地可能不足以保护其栖息地。有限和不连续的分布以及气候变化可能会限制马拉巴尔树蟾种群的扩散和生存,因此,在西高止山脉保护地内外加强对马拉巴尔树蟾栖息地的调查,是保护马拉巴尔树蟾种群生存的重要一步。总的来说,我们的研究结果展示了利用公民科学数据以及它在建模和理解难以捉摸的、树栖的和特有两栖动物物种的地理分布和鸣叫物候学方面的潜力。
