有效的保护措施在很大程度上取决于对目标物种栖息地选择的了解。丹顶鹤栖息地选择的尺度特征和时间节律尚不清楚，限制了丹顶鹤栖息地的保护。利用全球定位系统（GPS）对盐城国家级自然保护区的两只丹顶鹤进行了为期两年的跟踪。提出了一种多尺度方法来研究丹顶鹤栖息地选择的时空格局。结果表明，丹顶鹤对海三棱藨草、池塘、盐地碱蓬和芦苇的选择性较强，对雀鲷的选择性较差。在各季节中，海三棱藨草和池塘的生境选择率分别在白天和夜间最高。进一步的多尺度分析表明，在200米至500米尺度的海三棱藨草的覆盖率是最重要的预测所有的栖息地选择建模，强调恢复大面积的海三棱藨草栖息地丹顶鹤起重机种群恢复的重要性。此外，其他变量在不同尺度上影响栖息地选择，其贡献随季节和昼夜节律而变化。此外，栖息地适宜性被映射到栖息地管理提供了直接的依据。白天和夜间栖息地的适宜面积分别占研究区面积的5.4%~ 19.0%和4.6%~ 102%，说明恢复的紧迫性。这项研究强调了依赖于小生境的各种濒危物种的生境选择的规模和时间节奏。建议的多尺度方法适用于各种濒危物种栖息地的恢复和管理。(C)2020 Elsevier B.

Effective conservation measures largely depend on knowledge of habitat selection of target species. Little is known about the scale characteristics and temporal rhythm of habitat selection of the endangered red-crowned crane, limiting the habitat conservation. Here, two red-crowned cranes were tracked with Global position system (GPS) for two years in Yancheng National Nature Reserve (YNNR). A multiscale approach was developed to identify the spatiotemporal pattern of habitat selection of red-crowned cranes. The results revealed that Red-crowned cranes preferred to select Scirpus mariqueter, ponds, Suaeda salsa, and Phragmites austrolis, and avoid Sparlina oltemiflora. In each season, habitat selection ratio for Scirpus mariqueter and ponds was the highest during the day and night, respectively. Further multiscale analysis showed that the percent coverage of Scirpus mariqueter at the 200-m to 500-m scale was the most important predictor for all habitat selection modeling, emphasizing the importance of restoring a large area of Scirpus mariqueter habitat for red-crowned crane population restoration. Additionally, other variables affect habitat selection at different scales, and their contributions vary with seasonal and circadian rhythm. Furthermore, habitat suitability was mapped to provide a direct basis for habitat management. The suitable area of daytime and nighttime habitat accounted for 5.4%-19.0% and 4.6%102% of the study area, respectively, implying the urgency of restoration. The study highlighted the scale and temporal rhythms of habitat selection for various endangered species that depend on small habitats. The proposed multiscale approach applies to the restoration and management of habitats of various endangered species. (C) 2020 Elsevier B.V. All rights reserved.
