Wildlife Letters, EarlyView.Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Grasslands worldwide are experiencing severe degradation due to overgrazing, climate change and anthropogenic disturbances, resulting in substantial declines in biodiversity and ecosystem functioning.

Journal of Animal Ecology, EarlyView.This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Methods in Ecology and Evolution, EarlyView.Abstract Elliptic Fourier analysis (EFA) is often employed in geometric morphometrics (GM), but the normalization of elliptic Fourier descriptor (EFD) has persistently posed challenges for obtaining unique and comparable results, especially in the application of outline‐based GM methods, which limits the implementation in automated analysis of numerous,

, 2021 《生物多样性公约》第十五次缔约方大会(COP15)将评估全球生物多样性保护已有进展,审议并通过"2020年后全球生物多样性框架",后者是实现2050愿景"与自然和谐相处"的关键,有助于达成联合国可持续发展的目标。生物多样性资金机制现在是将来也是实施全球生物多样性保护行动计划的重要保证。根据《生物多样性公约》信息交换所的数据,目前各缔约方每年对本国生物多样性保护的投资额度占其当年国内生产总值(GDP)的比例比较小。中国作为发展中国家,2015年时生物多样性保护资金投入占GDP比例为0.255 ...

Inferring alternative ecosystem states with field survey data
Methods in Ecology and Evolution, EarlyView.Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Comprehensive framework for assessing and optimizing existing research networks
Conservation 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 ...

, 2016 近年来,生物多样性监测网络的建设得到广泛重视,全球、地区或国家生物多样性观测网不断组建。生物多样性观测的理论框架得到发展,提出了生物多样性核心监测指标(Essential Biodiversity Variables,EBV)。鱼类多样性监测的理论框架包含于生物多样性核心监测指标之内,在遗传、物种、生态系统等多层次进行。基于鱼类监测提出的生物完整性指数(index of biotic integrity,IBI)强调不同物种的生态功能,可以综合反映群落结构和功能的变化,得到广泛应用 ...

Conservation Biology, EarlyView.Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.
