A review of the lichens of the Dare Regional Biodiversity Hotspot in the Mid-Atlantic Coastal Plain of North Carolina, eastern North America

The results of a large-scale biodiversity inventory of lichens (including lichenicolous and allied fungi) in the Dare Regional Biodiversity Hotspot (DRBH) are presented. The DRBH is a region within the Mid-Atlantic Coastal Plain (MACP) of eastern North America that was recently delineated based on its unique and diverse lichen communities relative to other areas of the Atlantic Coast. Drawing on 4,952 newly generated voucher specimens from 49 sites, patterns of biodiversity and biogeography are presented and discussed within the context of both the DRBH and the broader MACP. Relationships between natural communities, vegetation, and lichen communities are discussed, as are threats to the lichen biota. A series of conservation actions are presented together with avenues for future study. In addition, supplementary resources are provided in the form of: (a) a checklist of DRBH lichens, lichenicolous fungi, and allied fungi; (b) keys to DRBH lichens and lichenicolous and allied fungi; and ...

本数据集呈现了达尔区域生物多样性热点区（Dare Regional Biodiversity Hotspot, DRBH）内地衣（lichen）、地衣生真菌（lichenicolous fungi）及近缘真菌（allied fungi）的大规模生物多样性调查（biodiversity inventory）成果。该区域地处北美东部的中大西洋沿海平原（Mid-Atlantic Coastal Plain, MACP）境内，因相较于大西洋沿岸其他区域拥有独特且多样的地衣群落，新近被划定为生物多样性热点区。本研究依托49个调查点位的4952份新制备的凭证标本（voucher specimens），针对DRBH及范围更广的MACP的生物多样性与生物地理学（biogeography）格局展开分析与讨论。研究同时探讨了自然群落、植被与地衣群落之间的关联，以及地衣生物群（lichen biota）所面临的各类威胁，并提出了一系列保护举措与未来研究方向。此外，本数据集还附带以下补充资源：(a) DRBH地衣、地衣生真菌及近缘真菌名录（checklist）；(b) DRBH地衣、地衣生真菌及近缘真菌分类检索表（keys）；以及……
