The Collision of Tradition, Technology, and Capitalism in American Hunting Culture 美国狩猎文化中传统、技术与资本的碰撞

open access: yesWildlife Letters, EarlyView.
This essay describes the context of big game hunting in the western United States in the twenty‐first century from a sociological perspective. Using Ogburn's theory of cultural lag as a guide, it explores the relationship of technology and capitalism to hunting.

小扭口藓(Barbula indica)芽胞发育特征的实验研究 [PDF]

open access: yes, 2005
在光照培养箱中人工对照培养小扭口藓(Barbulaindica(Hook. )Spreng)的芽胞,显微镜下观察并记录其发育成配子体的全过程。结果表明:小扭口藓芽胞在3 ~4d即可萌发; 10d左右开始分化出绿丝体、轴丝体及假根; 18d,轴丝体上的侧枝顶端细胞以分生缢割的方式产生单细胞或多细胞芽胞; 40d,轴丝体上开始出现配子体原始细胞;之后,配子体原始细胞发育成桑椹状的幼小配子体。还对芽胞形态发育、生理生态及配子体发生过程的特点进行了分析和讨论。,CN 23-1480/

Conservation Status, Decline Factors, and Strategies for Globally Endangered Musk Deer (Moschus spp.) in China 中国境内全球濒危麝属 (Moschus spp.) 物种的保护现状、致危因素及应对策略

open access: yesWildlife Letters, EarlyView.
This review summarizes the status of musk deer in China, highlighting severe population declines due to illegal hunting and habitat loss, and proposes integrated conservation strategies including habitat protection, captive breeding, and law enforcement to support the recovery and sustainable management of this ecologically and economically important ...

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

When and why to give shorebirds a head start

open access: yesConservation 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

Lessons from an eradication under multiple constraints of an island rat population of record density

open access: yesConservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

open access: yesConservation Biology, EarlyView.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

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 ...

Population genetic structure and phylogentic analysis for Morone americana in Delaware Bay of United States [PDF]

open access: yes, 2016
美洲狼鲈(Moroneamericana,Gmelin,1789)隶属于鲈形目(Perciformes),狼鲈科(Moronidae),狼鲈属(Morone),别名美洲白鲈、白石鮨。美洲狼鲈是在美国东海岸浅海区域十分常见的一种溯河洄游鱼类,每逢春末夏初,生活于近海和河口区域的美洲狼鲈便溯河洄游至河流中上游产卵繁衍。美洲狼鲈也经常被用作海区污染程度的指示种。鉴于美洲狼鲈广泛的分布范围以及巨大的种群数量,其十分适合作为近岸洄游性鱼类群体研究的模式种类。同时,其在检测环境污染方面也具有主要作用 ...

Differences in characteristics between naturalized threatened plants and other threatened plants

open access: yesConservation Biology, EarlyView.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.
