Simulating the efficacy of wolf–dog hybridization management with individual‐based modeling
Conservation Biology, Volume 39, Issue 1, February 2025.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 ...

Effect Structure of Iron Core on Kinetics of Iron Release from Horse Spleen Ferritin [PDF]
, 2001 建立H+参与马脾铁蛋白释放铁的动力学方程。H+以 1 / 2级反应方式参与铁蛋白释放铁核表层的铁。在酸性介质 ( pH 6 5)中 ,铁蛋白释放铁的总平均速率 ( 332Fe3+/HSF·min)比在碱性介质 ( pH8 0 )中释放铁的总平均速率 ( 73Fe3+/HSF·min)高 4 6倍。铁蛋白的铁核结构和外加的磷酸盐均能影响该蛋白释放铁的速率 ,但并不改变其反应级数。A Kinetic equation of iron release with H + existing was ...

Island restoration to rebuild seabird populations and amplify coral reef functioning
Conservation Biology, Volume 39, Issue 1, February 2025.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
Conservation Biology, Volume 39, Issue 1, February 2025.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 ...

, 2007 以鳞片作为鉴定年龄的材料,对龙溪河厚颌鲂(Megalobrama pellegrini)种群开展年龄结构与生长特性的研究。结果表明,厚颌鲂鳞片年轮结构呈疏密切割型,年轮特征显著,可用于年龄鉴定,3~4月是年轮形成高峰时间。种群由0~7龄共8个龄组组成,以低龄个体为主,1~3龄个体占83.14%,体长分布主要集中在130~250 mm间(77.71%)。体质量分布主要集中在50~250 g(64.33%)。群体总性比为♀∶♂=1∶1.03,符合1∶1理论比值。体长和鳞径呈直线关系 ...

野生动物学报, 1982 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 ...

Integrative Conservation, Volume 3, Issue 4, Page 330-341, December 2024.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 ...

Integrative Conservation, Volume 3, Issue 4, Page 294-311, December 2024.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

Wildlife Letters, Volume 2, Issue 4, Page 169-178, December 2024.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 ...
