Climatic changes and their impact are increasingly evident in Pakistan,especially in the mountainous regions. Mountain ecosystems are consideredto be sensitive indicators of global warming;even slight variationsin temperature can lead to significant shifts in local climate, which can,in turn, drastically affect the natural environment, subsequently alteringpeople’s lifestyle and wildlife habitats. The targeted area for the presentresearch was Lower Dir District, Pakistan. The study gathered the requiredinformation from primary and secondary sources. Secondary dataon temperature and precipitation were obtained from various sources,i.e., local CBO, including WWF Pakistan. Based on information gatheredon climate change and wildlife, a detailed questionnaire was *** showed that no regular pattern of the increase was found in temperaturefrom 2010 to 2018;the same was noticed in the rainfall decreasepattern. Results also showed that the leading causes behind climaticchanges are an increase in greenhouse gases due to pollution by industries,vehicles, crushing plants, deforestation, and some natural phenomenasuch as floods. The study showed that more than 80% of the respondentsagreed that climatic effects have a significant impact on wildlife, i.e.,the existence of wildlife falls in danger due to climatic changes as it maylead to habitat change, making it difficult for the survival and adaptationof the wildlife. Hence, in consequence, it leads to migration, low growthrate, an increase in morbidity and mortality rate, and finally leading to theextinction of the species or population. It is concluded from the study thatpeople are severely noticing the climatic change and its leading causesare greenhouse gases and deforestation. To control climatic changes andwildlife extinction, we need an appropriate policy for forest conservation,wildlife conservation, prevent hunting, industrial pollution control, vehiclepollution control, increase in plantation, awareness of

高山杜鹃(Rhododendron lapponicum)因其具有较高的园艺价值而被广泛种植。但随着种植时间的延长和规模扩大,一种新的根腐病引起高山杜鹃种植基地大量苗木死亡,且发病率等于死亡率。然而,其病原还不清楚。为了明确病因,笔者于2021年1月进行了实地考察和采集样品,利用组织分离法、柯赫氏法则、形态特征观察及β-tubulin、ITS、Ypt1基因序列分析对分离物做鉴定,同时探究了病原菌的生物学特征,测定了病原物在常见园林景观植物上的寄主范围和化学药剂的室内毒力,筛选了病原拮抗微生物。根据柯赫氏法则,接种分离物Pci-1能引起高山杜鹃枯萎死亡,重新分离物仍与Pci-1形态一致,证实了该菌株为病原菌。病原菌Pci-1在pH值7.0～8.0的OA培养基及27℃的培养条件下最适宜生长,菌落白色,菌丝无隔,培养后期易形成肿胀结构和孢子囊,孢子囊呈椭圆形或卵球形,一端呈乳突状凸起或无乳突状结构,成熟后释放出大量游动孢子;基于β-tubulin、ITS、Ypt1基因序列的系统发育树均显示分离物Pci-1与樟疫霉(Phytophthora cinnamomi)聚为一枝。综合形态学与分子片段序列结果,引起高山杜鹃根腐病的病原菌Pci-1为樟疫霉。在常见的60余种园林景观植物中,Pci-1能寄生蜀葵、油菜、桃、李、栾树、杜鹃、玉兰等10多种植物离体叶片并引起腐烂。高山杜鹃根际拮抗菌多粘类芽孢杆菌P2-5和棘孢木霉NY-1对Pci-1分别有明显的抑制作用和寄生作用。对病原菌Pci-1的EC,烯酰吗啉为0.196 5μg/mL,氟吗啉为0.732 0μg/mL,烯酰·霜脲氰为0.189 4μg/mL,氟菌·霜霉威为4.692 7μg/mL和精甲·咯菌睛为1.335 5μg/mL,以烯酰吗啉毒力最高。以上研究结果表明:樟疫霉能引起高山杜鹃严重的根腐病,且寄主范围广,对云南地区的高山杜鹃和自然生态系统构成潜在威胁。本研究能为樟疫霉引起病害防控提供科学依据。

Background: Basaloid epidermal proliferations (BEP), morphologically resembling basal cell carcinoma (BCC), have been described overlying dermatofibromas. Distinguishing the two is important because of non-aggressiveness of BEP and local aggressiveness of BCC. The aim of this study is to determine whether CK20 antibody staining for Merkel cells can be used as an adjunct method to differentiate BEP from BCC. Methods: Ten cases of BEP overlying dermatofibromas were selected. Ten cases of BCC were used as control. The two groups were stained with CK20 antibody. Numerical density of CK20 stained Merkel cells in peri-lesional epidermis, BEP and BCC was determined by examining 300 cells at 400X in two separate areas by three independent pathologists. To determine statistical significance, the results were compared using t-test method. Results: Density of Merkel cells in peri-lesional epidermis was 0.2-0.3%. No merkel cells were detected in the BCC. BEP overlying dermatofibromas showed an obvious increase in CK 20 stained Merkel cells. The difference was statistically significant(P < 0.02)Conclusions: We report a significant increase in CK20 stained Merkel cells in BEP overlying dermatofibromas as compared to BCC. CK20 antibody staining for Merkel cells can be used as an adjunct method to differentiate BEP overlying dermatofibromas from BCC.
