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.

Study on latitudinal gradient of species diversity in forest communities [PDF]
, 2015 森林群落结构和物种多样性的空间分异规律一直是生态学研究的热点问题。近年来，关于森林群落结构的描述与物种多样性的测定方法等研究也都有所发展，但这些研究大多是对森林生态系统的定性描述，而且方法不一，数据之间也缺乏可比性。 群落的组成结构是群落的重要标志，研究群落结构是研究群落物种多样性意义的理论基础，所以从群落组成结构的角度来探讨生物群落的物种多样性具有重要的意义，为进一步深入研究生物多样性功能及确定功能群提供理论基础 ...

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 ...

A study on the diet and nest site fidelity of Chinese egret (Egretta eulophotes) based on stable isotopic analysis [PDF]
, 2013 稳定同位素技术在考古学、地质学、医学、环境科学、海洋科学等中应用非常广泛。由于其特有优点，使其逐渐在动物生态学研究方面得到利用，如食性、食物链、营养结构、生境选择、迁徙等。黄嘴白鹭(Egrettaeulophotes)为全球数量稀少的濒危迁徙水鸟，对其开展深入研究、采取相应的保护迫在眉睫。本研究通过稳定同位素技术，对黄嘴白鹭的食性和繁殖地忠实度进行了初步探讨。 为保证本研究中能够科学地采样鹭科鸟类羽毛，减少濒危黄嘴白鹭羽毛样品的采集，对黄嘴白鹭及白鹭(Egrettagarzetta ...

Politics &Policy, Volume 54, Issue 1, February 2026.ABSTRACT Psychedelic interventions are not publicly available through Canada's healthcare system. Despite growing scientific evidence, public interest, and efforts to expand access to psychedelic therapies for end‐of‐life psychological suffering, Canadian policies remain restrictive.

Investigation on population dynamics of Fejervarya multistriata in plantations of Fujian Province, eastern China. [PDF]
, 2013 2011年6—9月和2012年4—5月,采用“围栏陷阱法“对福建省将乐县国有林场典型人工林内泽陆蛙种群进行调查,共捕获泽陆蛙222只。采用聚类分析方法,按照体长、体重将泽陆蛙划分为成体和亚成体,分析不同月份、不同类型人工林、不同林龄人工林内泽陆蛙的日均捕获量、肥满度和重长比的变化规律。结果显示:1)人工林泽陆蛙日均捕获量随月份变化先减小后增大,肥满度无显著变化,重长比先增大后减小。2)人工林泽陆蛙肥满度、重长比,混交林高于纯林;日均捕获量纯林高于混交林。3)随人工林林龄的增加泽陆蛙肥满度、重长比增大 ...
