摘要

意大利国家公园保护着重要的大西洋森林遗迹以及大量稀有的苔藓植物物种。我们重新评估了公园内高海拔地区特有或受威胁的45种苔藓植物的保护状况。保护分析遵循了国际自然保护联盟的指导方针。采用GeoCAT软件计算发生范围(EOO)和占用面积(AOO)。根据现场观察和文献资料对威胁媒介进行了表征。重新评估后,31种物种被认为是受威胁的,16种被认为是脆弱的(VU), 7种被认为是极度濒危的(CR), 8种被认为是濒危的(EN)。2种被认为是“近危”(NT), 3种被认为是“数据不足”(DD), 7种被认为是“最不关注”(LC)。该地区的主要威胁是野火和过度旅游,这些因素降低了栖息地质量,减少了它们的EOO和AOO。为尽量减少当地苔藓菌群即将遭受的损失而提出的建议包括鼓励研究和保护微生境。我们的研究结果旨在帮助制定Serra da Mantiqueira山脉的苔藓保护策略。

Regional risk assessment of high-altitude field mosses
The Itatiaia National Park protects important Atlantic Forest remnants as well as a large number of rare bryophyte species. We reassessed the conservation status of 45 species of endemic and/or threatened mosses occurring in high-altitude fields in the Park. The conservation analysis followed the International Union for Conservation of Nature guidelines. The GeoCAT software was used to calculate the Extent of Occurrence (EOO) and Area of Occupancy (AOO). The threat vectors were characterized based on field observations and data from the literature. After the reassessment, 31 species were considered threatened, with 16 being considered vulnerable (VU), seven critically endangered (CR), and eight endangered (EN). Two species were considered “near threatened” (NT) and three were considered “data deficient” (DD), and seven were considered “least concern” (LC). The main threats in that region are wildfires and excessive tourism - factors that lower habitat quality and reduce their EOO and AOO. Recommendations to minimize imminent losses of the local bryoflora include incentives for research and microhabitat protection. Our results are designed to aid in the elaboration of conservation strategies for mosses in the Serra da Mantiqueira mountains.

期刊介绍: Experimental, theoretical and applied papers on all aspects of plant (including algae) and fungi biology are welcome. The submitted manuscript or its essential content must not have been published previously or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English and show general interest. We expect that the submitted manuscript presents a great novelty in Botany, and this should attract a wide audience. Considering this, case studies are only considered if the narrative and implications are provided to be of general interest. Thus, manuscripts that report aspects of local interest are discouraged unless the implications of the findings are wide-reaching. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology. Please see below some details for specific area.
