Intangible drivers of tolerance shape human–elephant coexistence in Southwest China

People and Nature, EarlyView.
Abstract Southwest China is home to a small but rapidly expanding population of Asian elephants (Elephas maximus), whose growth has intensified conflicts with people living in shared landscapes. These conflicts result in substantial economic losses and occasional human casualties. This coexistence paradox—where conservation success leads to significant

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

Wildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Conservative roots confer a larger microbial carbon pump efficacy than acquisitive roots by regulating microbial life‐history strategy

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Alleviation of phosphorus rather than nitrogen limitation driven by permafrost and landscape effects on Dahurian larch forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

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.

When and why to give shorebirds a head start

Conservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

超声波辅助提取见血青总生物碱工艺研究

四川大学学报. 自然科学版, 2013
利用超声波辅助提取见血青(Liparis nervosa(Thunb.)Lindl.)总生物碱,研究了液料比、提取时间、乙醇体积分数、提取温度这4个因素对总生物碱提取率的影响,通过正交试验确定见血青中总生物碱的最佳提取工艺.结果表明,超声波辅助提取的影响因素顺序为提取温度>提取时间>乙醇体积分数>液料比.该研究得到了最佳的提取工艺为提取温度60℃,超声时间60min,乙醇体积分数80%,液料比1∶9,为见血青总生物碱工业化生产工艺的建立提供依据.

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

不同方法提取阴道加德纳菌细菌基因组DNA的比较

Zhongguo shiyan zhenduanxue, 2011
目的对阴道加德纳菌基因组DNA几种不同的提取方法进行比较,以利于细菌性阴道病的研究。方法采用几种不同方法提取阴道加德纳菌基因组DNA,对不同方法提取的细菌基因组DNA进行定量检测,以评价不同方法的提取效率。结果加德纳菌基因组DNA提取以改良法提取率较高,酚-氯仿抽提法、醋酸钾法次之,碱裂解煮沸法和溶菌酶煮沸法提取效率较差,加热煮沸法提取效率低。结论改良法提取GV基因组DNA效率较好,适用于临床应用。

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

Conservation Biology, EarlyView.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation
