Simulating the efficacy of wolf–dog hybridization management with individual‐based modeling
In the photo, an introgressed adult wolf–dog in the Northern Apennines, Italy, not far from the city of Bologna. Part of a research program, this male has been sterilized and released back in its own pack with a Global Positioning Collar. Abstract Introgressive hybridization between wolves and dogs is a conservation concern due to its potentially ...

Island restoration to rebuild seabird populations and amplify coral reef functioning
Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...

Integrating adult occurrence and reproduction data to identify conservation measures for amphibians
Abstract Monitoring programs are pivotal to establishing sound management. Due to economic, logistic, and time limitations, monitoring programs often overlook differences among life‐history stages. However, species occurrence does not necessarily mean population viability, and it is unclear to what extent monitoring programs that do not consider ...

本文通过笼养和野生棕胸竹鸡繁殖生态的比较表明:笼养棕胸竹鸡与野生棕胸竹鸡一样具有占区、求偶、交配、营巢和产卵等繁殖行为,但孵卵、育雏行为基本消失,这种变化的产生可能与环境条件和生理适应有关。

Despite the availability of data on plants and their pollinators from the Indian sub‐continent, detailed investigations that explain the intricacy of the mutualistic interaction at both population and community levels have largely been limited. This review explores the current status of pollination ecology research in India and suggests future ...

鸳鸯(Aix galericulata)这种珍贵鸟类,过去一般认为在贵州为冬候鸟。近来年,贵州省内的动物学工作者,观察到鸳鸯在贵州省的遵义、铜仁、贵阳和贵定等部分地区留居,并且积累了一些繁殖资料(吴至康等,1983)。但关于繁殖生态的研究,未见有系统的报导。为此,我们于1983年4—5月,在梵净山东南麓,对鸳鸯繁殖生态作了初步观察,结果如下。

Freshwater biodiversity in China is threatened by multiple anthropogenic factors, and while there are some reasons to suppose it may be possible to bend the curve of biodiversity loss, the variety of threats and their likely interactions with ongoing climate change provide little basis for optimism. For example, the historic overexploitation of Yangtze

赤胸鹀(Emberiza fucata fucata)是低山带草甸鸟类。主要在我国东北繁殖,越冬地在长江中下游及以南地区。关于赤胸鹀,山岸哲等(1971)曾在日本研究了它的越冬生态,牛山英彦(1968)做了繁殖期领地等问题的研究。对于赤胸鹀比较有系统的繁殖生态,尚未有报道。笔者于1980~1981年在长白山北坡对它的繁殖习性做了初步研究现将结果整理如下: 一、迁徙赤胸鹀每年4月下旬~5月上旬迁到长白山,8月末—9月初离开。其间停留130~150天左右 ...

Canada Warblers are declining sharply across their range throughout several genetically distinct population units, but habitat preferences are unknown for the population segment occurring in Pennsylvania, United States. We addressed this knowledge gap by leveraging machine learning methods and a large existing acoustic data set to uncover several ...
