Haiyang yu huzhao鲎作为生物进化史上的活化石，是一种极其珍贵的自然资源。近年来，人为因素导致鲎栖息地丧失日益严重。该研究运用MaxEnt模型对中国鲎与圆尾鲎在全球范围内的潜在栖息地进行了全面评估，并深入分析了其生态位特征。通过整合地理分布数据与环境变量，构建了高精度的生态位模型(中国鲎训练集AUC值为0.996 3, 测试集AUC值为0.995 8; 圆尾鲎训练集AUC值为0.998 0, 测试集AUC值为0.997 2)。研究结果显示，中国鲎与圆尾鲎的潜在栖息地分布存在显著差异，且均受到多种环境因素(水深 ...

Haiyang yu huzhao伪雄鱼是由雌鱼性逆转而成的生理性雄鱼，在全雌鱼苗种的规模化繁育过程中有着至关重要的作用，但国内外对其精子活力的研究较少。为研究黄姑鱼伪雄鱼繁殖期精子活力及环境因子对其活力的影响，利用计算机辅助精子活力分析系统(CASA)对伪雄鱼的精子密度、运动率、寿命和运动速度等指标进行测定；并且设置不同的温度和pH梯度组，探究不同环境因子对伪雄鱼精子活力的影响。结果显示，伪雄鱼精子密度为(2.60~2.24)×1010个/mL；在繁殖期内，伪雄鱼精子密度呈逐渐下降的趋势，且在排精中期和晚期 ...

投喂频率对横带髭鲷
Haiyang yu huzhao为探究投喂频率对横带髭鲷幼鱼生长性能、营养成分、消化酶活性及消化系统形态结构的影响，选用初始体重为(7.13±0.93) g的活力较好幼鱼，随机分为4组，每组3个重复，每个重复20尾鱼。4个实验组的投喂频率分别是1次/d (F1)、2次/d (F2)、3次/d (F3)、4次/d (F4)，试验持续8周。结果表明，随着投喂频率增加，终末体重、增重率、特定生长率、摄食率均有所上升，但F3和F4组没有显著差异，F4组较F1组终末体重增加了8.29 g、增重率提高了63%、摄食率提高了20 ...

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

Conservation Biology, EarlyView.Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, EarlyView.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Integrative Conservation, Volume 5, Issue 2, Page 192-204, June 2026.We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...
