Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

捻转血矛线虫(Haemonchus contortus)是反刍动物体内常见的寄生虫,圈养食草类野生动物感染捻转血矛线虫须引起重视,因其致病性更强,会增加宿主的死亡率。从捻转血矛线虫的病原学特点和诊断方法入手,对捻转血矛线虫病的防治技术,包括药物防治、免疫防治和生物防治进行综述,结合圈养食草类野生动物的饲养特点,提出加强饲养管理、营养供给和保护易感动物的措施,为圈养野生动物捻转血矛线虫病的防治提供参考。

月湖底泥疏浚后底栖动物群落的恢复及其与环境的关系 [PDF]
研究对月湖底泥疏浚后底栖动物群落动态进行逐月的周年调查,并分析了底栖动物密度、生物多样性与环境因子的关系,结果表明:疏浚导致大型底栖动物基本消失,现存量从疏浚前的(4387±885)ind·m-2降低至(80±21)ind·m-2。疏浚后,寡毛类成为受干扰系统恢复过程中的先锋种类,在春季(4月)和秋冬之际(11月)出现2个密度高峰,分别为(1010±230)ind·m-2和(1538±408)ind·m-2,而摇蚊幼虫在疏浚一年后的秋冬季密度达到高峰(2021±612)ind·m-2 ...

Research on Ammonia Emission Inventory in Fujian Province [PDF]
近年来,随着福建地区经济快速发展,城市化进度不断加快,环境与经济发展的矛盾日益突出,大气灰霾污染频繁发生,空气质量和能见度下降。氨是大气霾污染生成的促进剂,对大气污染有着直接和间接的影响。本研究建立了福建省人为源氨排放清单,分析氨的排放特征和时空分布,预测未来氨排放水平,探讨氨排放与氨监测和颗粒物离子的关系,为该地区空气质量改善提供了重要的基础数据。 首先,本研究以2013年为基准年,基于排放因子法建立了福建省人为源氨排放清单。研究显示,2013年福建地区人为源氨总排放量是25.24万吨 ...

川金丝猴圈养种群大多饲养在中国的动物园中。根据《川金丝猴国际谱系簿2009》记录,到2009年12月31日种群存活数量227只,包括野外出生个体、圈养出生个体。种群中圈养出生个体数量占主要部分,2009年占80.0%,种群的增加更多地依靠圈养出生个体数量的增加,近年种群发展出现停滞状态,种群的繁殖率下降、死亡率上升。主要是由于圈养出生个体的繁殖率低于野外捕获个体的繁殖率;育龄动物中圈养出生个体的死亡多发生在12 a以前,而野外捕获个体的死亡多发生在13 a以后。1 a以下幼仔的死亡原因与近亲繁殖、世代数、
