Abstract

Summary. Ecological responses of nocturnal predatory birds to forest cover and other geospatial predictors vary both geographically and taxonomically. Considerable knowledge gaps exist regarding the habitat associations of the Sri Lanka Frogmouth, a nocturnal bird restricted to Sri Lanka and the Indian Western Ghats. Via a 20-year island-wide survey, we searched for frogmouths in Sri Lanka to determine their habitat associations at both local and landscape scales and developed a habitat suitability model (HSM) to predict both current and future distribution. We confirmed frogmouth presence in 18% of the surveyed sites across all major bioclimatic zones (wet, intermediate, dry, and arid) from lower elevations (11-767m), comprising a broad geographic range. Frogmouth presence was mostly limited to forests (90%) with a few sites in agricultural mosaics. Land protection, altitude and both local and landscape-scale forest cover, as well as forest-cover loss at both spatial scales, were strong predictors of frogmouth presence. According to our HSM, the southwestern lowlands and parts of the intermediate zone contained the most suitable areas for frogmouths despite their smaller extent. Although the dry and intermediate zones contained extensive habitats for frogmouth, these regions were relatively less suitable. The habitat associations and geographic range of this species in Sri Lanka differ from that seen in India through negative associations with altitude and absence from montane zones, absence from degraded or severely disturbed habitats and independence from proximity to waterways. The Sri Lanka Frogmouth is sensitive to anthropogenic disturbances, including historical forest losses. We recommend landscape-scale conservation planning that incorporates both primary and mature persistent secondary forests to ensure the protection of this unique iconic species.—Karunarathna, S., Dayananda, S.K., Gabadage, D., Botejue, M., Madawala, M., Peabotuwage, I., Madurapperuma, B.D., Ranagalage, M., Udayakumara, A. & Surasinghe, T.D.

斯里兰卡蛙口蝠的分布、生境关联及保护现状

总结。夜间捕食鸟类对森林覆盖和其他地理空间预测因子的生态响应在地理和分类上都存在差异。斯里兰卡蛙嘴鸟是一种夜间活动的鸟类，只生活在斯里兰卡和印度西高止山脉。通过一项为期20年的全岛调查，我们在斯里兰卡寻找青蛙嘴，以确定它们在当地和景观尺度上的栖息地关联，并开发了栖息地适宜性模型(HSM)来预测当前和未来的分布。我们在低海拔(11-767米)的所有主要生物气候带(湿、中、干和干旱)的18%的调查地点确认了蛙嘴的存在，包括广泛的地理范围。青蛙嘴的存在主要局限于森林(90%)，在农业马赛克中有少数地点。土地保护、海拔、当地和景观尺度的森林覆盖，以及两个空间尺度上的森林覆盖损失，都是蛙嘴存在的有力预测因子。根据我们的HSM，西南低地和中间地带的部分地区虽然范围较小，但最适合蛙嘴的地区。尽管干旱和中间地带有广泛的蛙口生境，但这些地区相对来说不太适合蛙口。该物种在斯里兰卡的栖息地关联和地理范围与印度的不同之处在于，它们与海拔高度呈负相关，不在山地地带，不在退化或严重受干扰的栖息地，不靠近水道。斯里兰卡蛙嘴对人为干扰很敏感，包括历史上的森林损失。我们建议景观尺度的保护规划，包括原始和成熟的持久次生林，以确保保护这一独特的标志性物种。-Karunarathna, S.， Dayananda, s.k.， Gabadage, D.， Botejue, M.， Madawala, M.， Peabotuwage, I.， Madurapperuma, b.d.， Ranagalage, M.， Udayakumara, A.和Surasinghe, T.D.(2022)。斯里兰卡蛙口蝠的分布、生境关联及保护现状。农业学报，69:75-95。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
