克拉玛依农业开发区水土性状与荒漠植物多样性的关系

Shuitu Baochi Xuebao, 2004
通过分析克拉玛依农业开发区水土性状、荒漠植被演替规律和群落多样性,了解到区内植物的生长更新主要靠大气降水来维系,而土壤理化指标中的有机质、全N和全K含量增加是植物群落发展多样性的胁迫因素。与之相反,一定限度下的较高pH和粒度值,则可促进植物多样性水平的提高。分析结果还表明,土壤的全盐、全P和水分是影响植物多样性的潜在因素。

不同土地利用方式对红壤微生物多样性的影响

Shuitu Baochi Xuebao, 2003
试验采用碳素利用(BIOLOG)及磷酸酯脂肪酸(PLFA)法,研究了8种供试红壤微生物群落的功能多样性和结构多样性。两种方法均表明土地利用方式能显著影响微生物的多样性。采用磷酸酯脂肪酸法无需培养就能鉴别土壤微生物的组成结构,试验表明总PLFA含量与微生物生物量呈显著相关。碳素利用法的研究结果显示,茶叶园土中微生物对各类碳源的利用能力均很低,呈现出非常独特的微生物功能多样性。

Functional Stability Despite Taxonomic Changes in Mixed‐Species Foraging Flock Participants Along an Elevational Gradient in Knuckles Montane Reserve, Sri Lanka 斯里兰卡纳克斯山地保护区 (Knuckles Montane Reserve) 海拔梯度上混合物种觅食群参与者的功能稳定性与分类变化

Integrative Conservation, EarlyView.
This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Life Stage‐Specific Genetic Diversity and Landscape Characteristics Collectively Influence Genetic Recovery in Pometia pinnata Population 生活史阶段特异的遗传多样性与景观特征对番龙眼种群遗传恢复的协同影响

Integrative Conservation, EarlyView.
Pometia pinnata demonstrated life‐stage‐specific genetic responses to landscape features, with asymmetric gene flow patterns and population recovery following historical bottlenecks, revealing complex topographic and demographic influences on forest genetic structure.

Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

Integrative Conservation, EarlyView.
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 ...

A Preliminary Assessment of Noise‐Related Impacts From the Urban‐Invasive Johnstone's Whistling Frog (Eleutherodactylus johnstonei) 城市入侵物种约翰斯通鸣蛙 (Eleutherodactylus johnstonei) 引起的噪声影响初步评估 Una evaluación preliminar de los impactos relacionados con el ruido de la rana silbadora de Johnstone (Eleutherodactylus johnstonei), especie urbana invasora

Integrative Conservation, EarlyView.
The Johnstone's whistling frog is an invasive species whose loud night‐time calls may affect human health and well‐being. Our study in Cali, Colombia, combined fieldwork and online surveys to assess its urban occupancy, density, and potential health impacts.

Risk of Secondary Extinction in the Asian Songbird Trade, as Exemplified by the Selling of Crested Jayshrikes as Master Birds

Integrative Conservation, EarlyView.
The Asian Songbird Crises negatively affects so‐called master birds, species that are used to increase the song complexity of competitive songbirds. We assessed the trade in a master bird, the crested jayshrike, in Indonesia before and after its legal protection.

Are Galliformes of the High Himalayas Well Protected? Identifying Conservation Priority Areas Using an Assemblage‐Level Approach 高喜马拉雅地区的鸡形目鸟类是否得到了有效保护？利用群落水平方法确定优先保护区域

Integrative Conservation, EarlyView.
This study investigates distribution patterns of Galliforms in the Indian Himalayas, focusing on factors influencing their occurrence, regions of high diversity and endemism, and their overlap with protected areas. Our study highlights the need for assemblage‐level conservation strategies in high Himalaya which primarily relies on snow leopard‐focused ...

Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响

Integrative Conservation, EarlyView.
This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...
