澳门翼手类物种多样性调查 总被引:2,自引:0,他引:2
2009~2012年,对澳门翼手目(蝙蝠)物种多样性进行了调查.结果共捕捉到10个物种,属5科8属,其中包括澳门原来记载的2个物种,即蹄蝠科的大蹄蝠(Hipposideros armiger)和蝙蝠科的东亚伏翼(Pipistrellus abramus);本研究新增加8个物种,即狐蝠科的犬蝠(Cynopterus sphinx)和棕果蝠(Rousettus leschenaulti),鞘尾蝠科的黑髯墓蝠(Taphozous melanopogon),菊头蝠科的菲菊头蝠(Rhinolophus pusillus),以及蝙蝠科的大足鼠耳蝠(Myotis ricketti、普通伏翼(P.pipistrellus)、普通长翼蝠(Miniopterus schreibersi)和南长翼蝠(M.pusillus).另外,通过野外录音和分析,并与已发表物种声音特征比较核对,发现菊头蝠科和蹄蝠科各一种,前者可能是泰国菊头蝠(R.siamensis)或者中菊头蝠(R.affinis),后者可能是果树蹄蝠(H pomona)或者三叶蹄蝠(Aselliscus stoliczkanus).本文对已捕捉10种蝙蝠的分布、形态特征和回声定位叫声特征进行报道,同时对其种群数量和保护现状进行了讨论.保护蝙蝠栖息生境(洞穴、古老建筑和蒲葵树等)对保护澳门蝙蝠物种多样性至关重要. 相似文献

应用核基因重组激活基因1(Recombination activating gene,RAG1)部分序列对贵州9种菊头蝠和5种蹄蝠的系统发育关系进行了研究,运用贝叶斯法(Bayesian inference,BI)、最大似然法(Maximum likelihood,ML)和邻接法(Neighbor-joining,NJ)构建了系统进化树。研究结果表明:1.菊头蝠科和蹄蝠科形成两个平行的分支,支持它们是两个平行科的结论。2.马铁菊头蝠是菊头蝠科中第一个独立出来的亚分支,与其余8种菊头蝠的亲缘关系最远;Rhinolophus sp.与大菊头蝠聚合为一支,推测Rhinolophus sp.可能是大菊头蝠,或者是大菊头蝠的近缘种,它们是继马铁菊头蝠之后分离出来的第二亚分支;中华菊头蝠、栗黄菊头蝠、中菊头蝠聚合为第三亚分支,贵州菊头蝠、大耳菊头蝠、菲菊头蝠聚合为第四亚分支,此两分支形成姊妹群。3.在蹄蝠科的亚分支中,三叶蹄蝠、小蹄蝠、普氏蹄蝠依次分离出来,最后分出的是大蹄蝠和中蹄蝠。 相似文献

研究了同域分布的中华菊头蝠(Rhinolophus sinicus)与中菊头蝠(Rhinolophus affinis)的食性、形态、回声定位声波及捕食时间.中华菊头蝠与中菊头蝠均属于中等体型的菊头蝠,前臂长分别为(51.25±0.22) mm和(52.40±0.37) mm;悬挂状态下的回声定位声波均为典型的调频-恒频-调频(FM-CM-FM)型叫声,峰频分别为(82.07±0.17) kHz和(84.41±0.48) kHz.粪便分析显示中华菊头蝠与中菊头蝠分别捕食9目和7目昆虫,均以鳞翅目(Lepidiptera)和鞘翅目(Coleoptera)昆虫为主要食物(体积百分比总和> 90%),捕食鳞翅目昆虫的体积百分比差异显著,对猎物大小(以鞘翅目昆虫体长衡量)的选择无显著差异.中华菊头蝠与中菊头蝠的营养生态位宽度分别为2.38和2.28,重叠度达0.91,营养生态位未发生明显分化,但充足的食物资源促进了二者的共存.另外,2种菊头蝠的感官生态位和时间生态位未发生明显分化.由2种菊头蝠的翼载和峰频的差异推测二者发生了空间生态位和捕食微生境的分化,这也可能促进了二者的共存. 相似文献

Some closely related members of the monocotyledonous familiesAlismataceae, Liliaceae, Juncaceae, Cyperaceae, Poaceae andAraceae with variable modes of pollination (insect- and wind-pollination) were studied in relation to the ultrastructure of pollenkitt and exine (amount, consistency and distribution of pollenkitt on the surface of pollen grains). The character syndromes of pollen cementing in entomophilous, anemophilous and intermediate (ambophilous or amphiphilous) monocotyledons are the same in principal as in dicotyledons. Comparing present with former results one can summarize: 1) The pollenkitt is always produced in the same manner by the anther tapetum in all angiosperm sub-classes. 2) The variable stickiness of entomophilous and anemophilous pollen always depends on the particular distribution and consistency of the pollenkitt, but not its amount on the pollen surface. 3) The mostly dry and powdery pollen of anemophilous plants always contains a variable amount of inactive pollenkitt in its exine cavities. 4) A step-by step change of the pollen cementing syndrome can be observed from entomophily towards anemophily. 5) From the omnipresence of pollenkitt in all wind-pollinated angiosperms studied one can conclude that the ancestors of anemophilous angiosperms probably have been zoophilous (i.e. entomophilous) throughout. 相似文献

<正>Dear Editor,Infectious bursal disease (IBD) is one of the most important diseases of the poultry. The IBD virus (IBDV), a nonenveloped virus belonging to the Birnaviridae family with a genome consisting of two segments of double-stranded RNA (segments A and B), targets B lymphocytes of bursa of Fabricious leading to immunosuppression. In Pakistan,poultry farming is the second biggest industry and IBD is the second biggest disease threating the poultry sector.However, there is limited genome information of IBDV 相似文献

正Dear Editor,Mink circovirus (MiCV), which is clustered in the genus Circovirus of the family Circoviridae, was first described in minks from farms in Dalian, China in 2013 (Lian et al.2014). The complete single-stranded circular genome of the virus is 1,753 nucleotides long and contains two major open reading frames (ORFs), designated ORF1 (Rep gene)and ORF2 (Cap gene)(Lian et al. 2014; Ge et al. 2018).Sequence analysis has shown that MiCV is most closely 相似文献

Cyclophilin A (CypA) is a peptidyl-prolyl cis/trans isomerase that interacts with the matrix protein (M1) of influenza A virus (IAV) and restricts virus replication by regulating the ubiquitin–proteasome-mediated degradation of M1. However,the mechanism by which CypA regulates M1 ubiquitination remains unknown. In this study, we reported that E3 ubiquitin ligase AIP4 promoted K48-linked ubiquitination of M1 at K102 and K104, and accelerated ubiquitin–proteasome-mediated degradation of M1. The recombinant IAV with mutant M1 (K102 R/K104 R) could not be rescued, suggesting that the ubiquitination of M1 at K102/K104 was essential for IAV replication. Furthermore, CypA inhibited AIP4-mediated M1 ubiquitination by impairing the interaction between AIP4 and M1. More importantly, both the mutations of M1 (K102 R/K104 R) and CypA inhibited the nuclear export of M1, indicating that CypA regulates the cellular localization of M1 via inhibition of AIP4-mediated M1 ubiquitination at K102 and K104, which results in the reduced replication of IAV.Collectively, our findings reveal a novel ubiquitination-based mechanism by which CypA regulates the replication of IAV. 相似文献
