Wild Pigs (Sus scrofa) Stand Their Ground: Investigating Flight Response, or Lack Thereof, to Perceived Predation Risk 野猪坚守原地:探究其面对感知捕食风险时的逃逸反应 (或无逃逸行为)

open access: yesWildlife Letters, EarlyView.
We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

Extreme site fidelity in long‐distance migratory shorebirds in Australia and potential implications for conservation

open access: yesConservation Biology, EarlyView.
Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

open access: yesConservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

Comparing screening outcomes for private sector nature‐related assessments based on national and global biodiversity datasets

open access: yesConservation Biology, EarlyView.
Abstract In response to demand for better biodiversity stewardship from the private sector, frameworks such as the Taskforce on Nature‐related Financial Disclosures (TNFD) have been developed to help companies assess, manage, and disclose their nature‐related impacts, dependencies, risks, and opportunities.

Protected areas on international borders show uneven conservation outcomes

open access: yesConservation Biology, EarlyView.
Abstract Border protected areas (BPAs) are national protected areas that are immediately adjacent to a country's border or span two or more countries; they are characterized by distinctive opportunities and pressures. They play a critical role in protecting carbon‐rich ecosystems, conserving endangered biodiversity, reducing cross‐border environmental ...

A framework for integrating resilience indicators into risk assessments

open access: yesConservation Biology, EarlyView.
Abstract Globally, ecosystems are increasingly threatened by climate change and human pressures, yet ecosystem risk assessments predominantly emphasize exposure to stressors while overlooking intrinsic ecosystem resilience—the capacity to absorb and recover from disturbances.

From Indicator to Prediction: Five Decades of Biochemical Oxygen Demand Research in Tropical Freshwaters

open access: yesWorld Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT Biochemical oxygen demand (BOD) remains a core indicator of organic pollution in freshwater monitoring, but its role in water policy and practice is changing as water‐quality assessment moves toward predictive, integrative, and decision‐support approaches.

自然灾害风险评估与分级方法论探研——以山西省地震灾害风险为例

open access: yes, 2011
自然灾害发生的可能损失一直是灾害风险评估上的难题。本研究以自然灾害风险评估经典模型为基础,提出了新的自然灾害风险评估与风险等级划分方法,利用历史灾情和孕灾环境解决风险评价中致灾因子破坏力与灾害发生的可能,并以山西省地震灾害风险为例进行了定量化评估研究。主要改进在于:确定灾害损失率和环境参数以建立地震灾害可能损失计算模型,计算承灾体地震灾害风险的可能损失量;用标准差和对数位转换的相关计算对地震灾害风险等级进行划分。案例结果显示:山西全省发生地震灾害,可能损失风险包括房屋破坏风险超过3百万间 ...

The New World Order and National Security Dynamics of African States: Case Studies of Cameroon and Mali

open access: yesWorld Affairs, Volume 189, Issue 4, Winter 2026.
ABSTRACT The move from unipolarity to a fluid and contested multipolar world order has significantly changed the way African nations form national security policy due to changes in the nature of the strategic environment of those states. Much of the literature has focused on how the actions of major world powers ‐ the United States, China and Russia ...
