Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

Hobbyist preferences for pet freshwater turtles
Conservation Biology, EarlyView.Abstract The burgeoning pet trade is a primary threat to wild freshwater turtles worldwide. Although the risks from commercial exploitation of turtles have been discussed widely, there is little empirical research on preferences for pet turtles from a hobbyists’ perspective.

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

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

野生动物学报, 2023 鹿类角柄终生有2次发育，第1次在胚胎期，第2次在青春期，出生后角柄的激活和首次发育对于鹿角再生极为重要，角柄的青春期发育对于鹿类个性及等级序位形成、鹿角大小、争夺配偶、种间竞争和应对天敌等有重要意义。利用红外测距仪，开展麋鹿（Elaphurus davidianus）角柄生长发育的宏观测量，结合青春期骨膜组织取样、血液激素水平和信号通路表达情况检测，对麋鹿角柄发育情况进行研究。结果表明：与成年不同，幼龄雄性麋鹿在第1年秋季开始出生后的首次角柄发育，由毛旋处长出骨质突起，翌年2—3月角柄长至2.5~3.0

Roles of Receptor UNC5B in Vascular Development and Tumor Metastasis [PDF]
, 2012 血管和神经系统都构成复杂的分支网络，遍布身体的各个区域，并提供信息的双向流动（感觉和运动神经元；动脉和静脉血流）。在体内分布上血管和神经纤维也总是相伴而行到达同一远隔靶位，二者在结构和功能上的相似性，暗示着它们可能受到某些共同信号分子调控。很多神经导向因子都参与了对血管生长发育的调节。UNC5B是首个被证实参与血管发育调控的UNC5受体。但目前对于UNC5B在血管发育中的作用因所使用的动物模型以及UNC5B基因敲除后对表型分析的不同而存在很大的争议，争议的焦点在于UNC5B是促进，还是抑制血管的发育 ...

野生动物学报, 1984 麝的生长发育与外形表现有密切联系,了解麝的生长发育规律对麝的外貌鉴定,指导麝的育种、饲养管理及仔麝的培育等生产实践具有重要意义。为了调查麝的生长发育规律,我们在1970—1981年,在汪清县各地区进行了初步调查,收到了一定效果。现将调查结果介绍如下:
