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

open access: yesIntegrative 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

open access: yesIntegrative 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 ...

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

open access: yesIntegrative 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 ...

Internal physiological drivers of leaf development in trees: Understanding the relationship between non‐structural carbohydrates and leaf phenology

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

近视眼患者角膜屈光力与角膜表面对称性的相关性分析

open access: yesZhongguo shiyan zhenduanxue, 2005
目的探讨近视患者角膜屈光力与角膜表面对称性的相关关系。方法对近视患者眼1472只(其中男性眼715只,女性眼757只)、行PRK手术后1年的患者眼161只和行LASIK手术后1年的患者眼158只进行统计学分析,研究角膜平均屈光力(ACP)与角膜表面非对称指数(SAI)的相关关系。结果ACP与SAI在男性和女性中均存在明显的正相关关系(Pearson相关系数为分别为0·120、0·108 ...

How much biotic nativeness matters across human demographic groups

open access: yesConservation Biology, EarlyView.
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

光接入网链路状态信号相关性判据方法

open access: yesGuangtongxin yanjiu, 2019
针对二维光编解码接入网链路监测系统中多路距离相近用户信号叠加难以设置阈值的问题,提出了一种基于信号相关性的链路状态识别算法。该算法以正常信号为基准,对实时检测的信号进行信号相关性分析,根据带补偿自定义相关系数及系统的编码规则判断具体分支链路状态。搭建了32用户、3路等距实验系统,等距离链路断路个数为1时,相关系数为0.626 1;断路个数为2时,相关系数分别为0.342 1、0.386 5,均在阈值区间内。仿真结果表明 ...

Comprehensive framework for assessing and optimizing existing research networks

open access: yesConservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.
