Regulation of Plasmodium yoelii Oocyst Development by Strain- and Stage-specific Small Subunit rRNA [PDF]
, 2015 疟疾是一种由疟原虫引起的，通过雌性按蚊作为媒介传播的全球性急性寄生虫病。疟原虫的一个独特的特点是在其生活史的不同发育阶段，有转录不同、结构发育期特异性的核糖体RNA（rRNA）起不同的作用；A型基因的转录主要在无性阶段，而S型基因主要在有性阶段或者是蚊期阶段特异表达。然而，至今还没有明确的功能性证据证明不同的rRNA在疟原虫发育的不同阶段能起到特异的作用。我们实验获得了一个具有卵囊发育缺陷表型的约氏疟原虫虫株，缺陷表型表现为卵囊发育较小、迟缓、并且不能发育为有感染力的子孢子 ...

Wildlife Letters, EarlyView.Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Mating system, brood parasitism and extra-pair behaviour in the Chinese egret (Egretta eulophotes) basing on the microsatellite technology [PDF]
, 2015 动物的婚配制度影响着个体的繁殖成功率，直接关系到群体的遗传多样性和种群动态的发展变化，是保护遗传学和生态学领域中非常重要的研究内容。已有学者野外观察到黄嘴白鹭（Egrettaeulophotes）存在婚外交配（EPC）行为，然而，有关黄嘴白鹭的婚配制度、EPC的产生机制以及其是否会导致婚外父权（EPP）现象还未清楚。此外，许多集群繁殖的鸟类都存在种内巢寄生（CBP）现象，而关于黄嘴白鹭巢寄生行为的研究也尚未开展。因此，本研究围绕黄嘴白鹭的婚配制度问题，主要开展以下几方面研究： （1）对3种非损伤性样品 ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.
