动物园圈养种群的遗传学管理

open access: yes野生动物学报, 2004
随着自然环境的不断变化,许多物种受到野外生存环境的压力越来越大,已经濒临灭绝,建立圈养种群是对这些濒危物种进行保护的一种有效方法。如何使圈养种群长期健康地生存下去,并能够支持将来野生种群的恢复是现代动物园工作中需要解决的问题,为了达到这个目的,科学地对濒危珍稀物种圈养种群进行遗传学管理是非常重要的。

The Relationship of Environmental Factors with Community Structures and Diversities of Microorganisms in Activated Sludge from Wastewater Treatment Plants [PDF]

open access: yes, 2013
随着我国社会经济的飞速发展和城镇化进程的加快,大量肆意排放的废水造成水体严重污染,导致“水危机”日趋严重。废水在排入水体前,应首先由污水处理厂进行处理。较之于增加污水处理厂数量需要耗费大量资金成本,提高现有污水处理设施的废水处理效率至关重要。活性污泥法是污水处理厂应用最广泛的废水处理方式之一。由于在活性污泥系统中,微生物是去除污染物的主体。因此,深入了解活性污泥中微生物的群落结构与功能,理解其时空分布格局及受控机理,对于深化认识污水处理系统的本质,进而提高污水处理效率具有重要意义。此外 ...

科尔沁沙地草地退化过程中的物种组成及功能多样性变化特征

open access: yesShuitu Baochi Xuebao, 2006
科尔沁沙地草地退化、沙漠化过程存在着疏林草地、沙质草场、半流动沙地和流动沙地等明显的逆行演替阶段,并且不同的阶段对应着适合本生境的典型群落类型,每一群落优势种的作用明显。草地退化过程中,原生地带性群落及演替早期群落物种丰富、多样性高.结构复杂,随着草地退化、沙漠化过程,群落组成物种数、科属减少.禾本科植物衰退,物种多样性降低,草地群落结构趋于简单、质量下降。在退化的各个阶段,一年生、二年生和旱生植物功能群在各个阶段始终保持着较高的优势地位.对群落生态功能的发挥和维持起着重要作用 ...

Sequencing and correlation analysis of miRNAome and transcriptome of Larimichthys crocea infected by Cryptocaryon irritans [PDF]

open access: yes, 2016
大黄鱼(LarimichthyscroceaRichardson,1846)曾是我国的传统四大海洋渔业对象之一,也是我国目前最主要的海水网箱养殖经济鱼类之一,2015年养殖年产量超过14万吨。近年来由于发展模式的制约,养殖管理的缺失,加之养殖环境的严重污染,大黄鱼养殖过程中的各种病毒性疾病,细菌疾病和寄生虫疾病日趋严重,其中以刺激隐核虫(Cryptocaryonirritans)病的危害最为严重。其所感染大黄鱼并导致继发性的细菌感染,造成养殖大黄鱼大面积死亡,对该养殖产业损失极大 ...

加勒比海的火烈鸟

open access: yes野生动物学报, 1993
加勒比火烈鸟是世界上五种火烈鸟中的第二大种,但是由于她味道太美,尤其是那肥厚的舌头,使她的种群在1950年已经减少到12只,几乎濒临灭亡!(根据罗伯特·波特·阿伦调查,罗伯特是巴哈马奥特朋协会研究主任。) 1952年,情况有所好转,罗伯特在巴哈马群岛最南部的Lnagua岛发现这里留居着一个大种群,足有一千多只,一个真正的繁殖群,足够帮助加勒比群岛的其他地方重建种群。原来 ...

Twelve Years Revisited: Translanguaging as Relational Pedagogy for Sustaining Language Learning Motivation

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...
