{"title":"Ecology and Current Distribution of Three Habitat-Specialized Land Snail Species of the Genus <i>Vertigo</i> (Gastropoda: Eupulmonata) in Europe.","authors":"Radovan Coufal, Veronika Horsáková, Tomáš Peterka, Julien Ryelandt, Grita Skujienė, Michal Horsák","doi":"10.6620/ZS.2024.63-19","DOIUrl":"10.6620/ZS.2024.63-19","url":null,"abstract":"<p><p>Our understanding of species distribution and ecology is critical to properly assess their conservation status. <i>Vertigo lilljeborgi</i>, <i>V. genesii</i>, and <i>V. geyeri</i> have the centre of their current distribution in northern Europe, where their occurrence is relatively frequent. However, to the south their occurrence is fragmented and restricted to sites of late glacial/early Holocene origin. In the last ~30 years, there has been an increase in records, connected with the listing of the latter two species in Annex II of the EU Habitats Directive (94/43/EEC). However, there is no comprehensive publication documenting their pan-European distribution. Therefore, we assembled all available data from online databases, books, and scientific literature and combined them with our unpublished records to create distribution maps. The results show a more frequent occurrence in temperate Europe than previously known, especially for <i>V. geyeri</i>. Analyses performed on data from 327 ecologically potentially suitable sites, covering the entire distribution range of the species, have improved our knowledge of their ecology. <i>Vertigo lilljeborgi</i> and especially <i>V. genesii</i> are restricted to areas with lower summer and winter temperatures, and therefore, their further decline is expected in the face of rising temperatures due to climate change. The preference of <i>V. geyeri</i> for higher temperatures, in comparison to the latter two species, may explain its relatively frequent distribution in temperate Europe. <i>Vertigo lilljeborgi</i> favors base-poor sites, while <i>V. genesii</i> and <i>V. geyeri</i> prefer calciumrich sites, with the latter being the most calcicolous. Their need for a stable water regime and lowproductive sites, known from previous studies, was not conspicuous in our results, probably due to the selection of sites well within the species range. Despite the increase in record frequency, these species are still endangered, especially in temperate Europe. Their sites should therefore be strictly protected as sites of high biological diversity and conservation value. Because of their relict nature, these land snails should be considered umbrella species and indicators of well-preserved groundwater-dependent ecosystems in temperate Europe.</p>","PeriodicalId":49331,"journal":{"name":"Zoological Studies","volume":"63 ","pages":"e19"},"PeriodicalIF":1.5,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11629111/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142808373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that their suitable habitats during LIG and LGM were mainly in eastern Southwest, Central, and Coastal China. A noticeable distribution reduction started in LIG and persisted until the present (1970-2000). Their distribution centroid would shift northward to mountainous regions, mainly in Southwest China, where more migration corridors would be available for their prospective development. Also, the results indicate that China's Protected Area currently does not cover more than 94.00% of macaques' potential habitats, which is a dismal situation for their conservation.

This study analyzed Hawai'i Island data: stranding location, date, size, sex, presence/absence of tumors, stranding status, and cause of stranding. A total of 754 stranded green turtles was reported from 1983-2022: 379 stranded on the east (windward) coast of Hawai'i Island and 375 on the west (leeward) coast. Strandings peaked in 2011 and 2018 and were highest from March to August. The most common known cause of stranding was hook-and-line fishing gear (21.4% of total strandings), followed by fibropapillomatosis (7.2%), human take (4.4%), miscellaneous (3.7%), boat impact (3.3%), shark attack (3.2%), and net (2.1%); however, 54.8% of strandings had no known cause. Statistical modeling did not provide convincing evidence of temporal changes in the distribution of strandings across three consolidated cause categories: human-caused; predation, disease, and weather; and unknown. Stranded turtles on east Hawai'i Island had a higher frequency of fibropapillomatosis, whereas west Hawai'i stranded turtles showed higher incidence of shark attacks. These results provide the first comprehensive analyses of stranding data from Hawai'i Island and provide information that can inform resource managers, policy makers, and the public about the various types and magnitudes of impacts, anthropogenic and natural, to green turtles so that mitigation measures can be put into practice.
