Preliminary Studies on the Nestling Growth，Hatching and Reproductivity of Three Specices of Herons [PDF]
, 2009 本实验于2006～2008年间在厦门的鸡屿、大屿、大兔屿，漳浦的菜屿列岛和福鼎的日屿岛初步调查了黄嘴白鹭（Egrettaeulophotes）、白鹭（Egrettagarzetta）和池鹭（Ardeolabacchus）的繁殖生态，取得了三种鹭的窝卵数、卵的大小、孵化率和成活率等生物学数据，对白鹭进行了鹭鸟卵和雏鸟的识别实验，对白鹭和池鹭研究了窝卵数人为改变对亲鸟繁殖行为及雏鸟成活的影响，对黄嘴白鹭卵进行了人工孵化和雏鸟人工养殖的探讨。 三种鹭的窝卵数分别是白鹭3.69±0.70枚（n=16），池鹭3 ...

Regulatory compliance and support for altered management of the exotic pet trade
Conservation Biology, EarlyView.Abstract Globally, the exotic pet trade has contributed to species invasion, disease, and animal welfare risks. Although scientists have advocated for increased trade regulation, the success of management and regulatory efforts depends on compliance by participants in the exotic pet trade. We used a regulatory compliance framework to investigate exotic

Studies on Migration of Bursaphlenchus xylophilus and the Extracts from medium cultured with Botrytis cinerea and it's inducing activity to B.xylophilus [PDF]
, 2007 摘要“松材线虫早期检测管诊断管”能从松树上诱引到松材线虫(Bx)，为了研究其作用的机理，本论文设计了一条新的思路，分别以灭菌的淡水沙和水琼脂平板为基质，研究了各种因素对Bx移行的影响，并从灰葡萄孢发酵液中逐级分离提取各种组分，以滤纸片法分析其中对Bx移行起诱引作用的物质。主要结果如下：病木对Bx的诱引力较强，经高压灭菌后诱引能力虽有所下降，但差值不大，说明在病木中对Bx起诱引作用的物质并没有因高压灭菌而完全失去，这与某些人“吸引物质为挥发性物质”的推测相左；但松皮浸出液对Bx并没有什么明显的吸引作用 ...

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.

Mechanisms of Heavy metals enriching and excreting in Egretta eulophote and Impact of Colonial Breeding on Heronry Soils [PDF]
, 2010 本研究采用电感耦合等离子质谱（ICP-MS）对取得的相关样品进行了钒（V）、铬（Cr）、锰（Mn）、镍（Ni）、铜（Cu）、锌（Zn）、砷（As）、硒（Se）、镉（Cd）和铅（Pb）等10种重金属元素含量的测定。 为了研究黄嘴白鹭体内各重金属富集的主要部位、重金属排除的机制及在其食物链中富集规律，我们对厦门大屿岛白鹭自然保护区内人工养殖过程中自然死亡的8只黄嘴白鹭(Egrettaeulophotes)（约30日龄）的肝脏、肾脏、肌肉、心脏、骨骼、卵壳和羽毛等组织器官以及饲喂的水样、食物 ...

Wildlife Letters, Volume 4, Issue 1, Page 10-22, March 2026.In this study we analyze the role of phylogeny, environment, and community structure on sociality. Using structural equation modeling (SEM) we aim to quantify the direct and indirect impacts of variables on behaviors including social grouping, reproduction, and space use among Carnivora species.
