Informing spatial conservation prioritization with species’ traits
Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

伴随气候变化下亚热带地区米槠天然林净初级生产力变化,凋落物以及植物根系输入亦会发生改变,这将显著影响土壤微生物群落。于2019年7月在设置7年的米槠天然林植物残体添加和去除试验(the detritus input and removal treatments,DIRT)样地采集不同处理(对照、去除地上凋落物、去除地下根系、无凋落物输入、添加双倍地上凋落物)的2个土层土壤(0—10,10—20 cm),测定微生物磷脂脂肪酸(phospholipid fatty acid,PLFA)含量 ...

Phytoplankton diversity in Futian mangrove wetland of Shenzhen:Composition and distribution [PDF]
根据深圳福田红树林湿地的浮游植物周年调查资料,分析浮游植物群落多样性的组成与时空分布特征,并利用浮游植物群落多样性指数对湿地水体的营养状态进行评价。共记录浮游植物5门28属51种,各季度浮游植物数量均超过106Ind.l-1。硅藻分布广泛,在种类和数量上均占主导地位,优势种为微小小环藻(CyClOTEllA CASPIA)和诺氏海链藻(THAlASSIOSIrA nOrdEnSkIldI)等,耐受污染的藻类,如小颤藻(OSCIllATOrIA MInIMA)、鱼形裸藻(EuglEnA ...

Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

Effect of heron nesting on the nitrogen and phosphorus cycles of Acacia confuse forest in uninhabited island [PDF]
鹭鸟是鹭科(Ardeidae)鸟类的总称,在我国分布极广,是湿地生态系统中重要的生物类群之一。鹭鸟多营巢于树、竹上,主要以幼鱼、虾、水生昆虫等水生生物和两栖类为食。当其归巢休憩时,会为营巢地带来数量可观的鸟粪。由于鸟粪中富含氮磷元素,必然会对营巢地森林生态系统的氮磷循环产生影响。本研究选取典型无居民海岛厦门市大屿岛白鹭自然保护区的鹭鸟营巢地台湾相思林(Acaciaconfuse)为试验对象,主要通过林地土壤和凋落物研究结合15N自然丰度法,揭示鹭鸟营巢对于森林生态系统氮磷循环的影响 ...

沿海拔梯度选取不同植被群落的12个样地,通过陷阱及铗日法对秦岭南麓中、东段不同群落中小型兽类物种多样性及分布进行调查,累计2 968个工作日,捕获小型兽类2目6科21种,266只,平均捕获率711%。香农-维纳指数和均匀度指数显示,物种多样性在栎林落叶阔叶林最高,农耕带最低。秦岭中段物种多样性呈现出较为明显的中海拔分布格局,而东段的分布格局不甚明显。此外,两区域常见种存在差异,中段主要为中华姬鼠(Apodemus draco)和四川短尾鼩(Anourosorex squamipes),而东段为大林姬鼠(

Mycorrhiza‐induced alterations in the spatial structure of stands in a subtropical forest
Read the free Plain Language Summary for this article on the Journal blog. Abstract Spatial aggregation patterns represent snapshots of ecological processes that occurred over an extensive period. Such processes can shape both the conspecific and the heterospecific spatial structure of plants across woody habitats.
