Abstract

Abstract Vascular epiphytes represent a remarkable characteristic of the tropical cloud forests. The Serra da Mantiqueira (SM) represents one of the main highland areas of Brazil harboring vegetation remnants, and highlighting the cloud forests. We present a checklist of the vascular epiphytes found in the cloud forests of the SM, discussing the data about taxonomic representativity, distribution in the phytogeographic domains, habits, threatened status in Brazil and the states comprising the SM (Espírito Santo-ES, Minas Gerais-MG, Rio de Janeiro-RJ, São Paulo-SP). Field expeditions were performed between 2012 and 2019, as well as data gathering from scientific collections and published articles. We found 678 species, representing approximately 20% and 30% of the species found in Brazil and Atlantic forest, respectively. The richest families (Orchidaceae, 288 spp.; Bromeliaceae, 112 spp.; Polypodiaceae 65 spp.) corroborated the patterns found in different scales. Forty-one species are threatened nationally (and regionally, there are 149 in ES, 55 in MG, six in RJ, 31 in SP). These numbers of richness and threatened species highlight the relevance of directing efforts toward knowledge and conservation of both cloud forest remnants and SM as a whole, under pain of losing of a large part of the floristic diversity of Atlantic forest.
巴西东南部曼蒂奎拉山云雾林中的维管附生植物
维管附生植物是热带云雾林的一个显著特征。Serra da Mantiqueira (SM)代表了巴西主要的高原地区之一,这里有植被遗迹,并突出了云雾森林。我们列出了在巴西云林中发现的维管附生植物的清单,讨论了在巴西和构成巴西云林的州(Espírito santos - es, Minas Gerais-MG,里约热内卢de Janeiro-RJ, s o Paulo-SP)的分类代表性,植物地理域分布,习性,受威胁状况的数据。在2012年至2019年期间进行了实地考察,并从科学收藏和发表的文章中收集数据。我们发现了678种,分别约占巴西森林和大西洋森林中发现物种的20%和30%。最富有的科(兰科,288种;凤梨科,112种;水蛭科(65 spp.)证实了在不同尺度上发现的模式。41个物种在全国范围内受到威胁(从区域来看,ES有149个,MG有55个,RJ有6个,SP有31个)。这些丰富度和受威胁物种的数量突出表明,在大西洋森林植物区系多样性大量丧失的痛苦下,指导对云雾林残余和整个大西洋森林的认识和保护的努力具有重要意义。
