Graziano","doi":"10.3119/22-22","DOIUrl":"https://doi.org/10.3119/22-22","url":null,"abstract":"Aldrovanda vesiculosa L. (Droseraceae), the waterwheel plant, is a globally rare submerged aquatic carnivorous plant with extraordinarily fast-closing snap-traps and a highly specific suite of ecological requirements (Cross 2012). Plants are perennial, freefloating, and rootless, with linear, sparsely branched stems bearing whorls of 4–9 leaves terminated by bristles and a solitary, bi-lobed trap. The species is fast growing under optimal conditions and reproduction is predominantly clonal through the detachment of branches during favorable summer conditions (Adamec 1999). Plants overwinter by forming vegetative dormant turions at their apices in autumn. This stenotopic species usually grows in shallow, standing, dystrophic waters (Adamec 2018). The species is native to Europe, Africa, Asia, and Australia yet, due to recent rapid habitat degradation and population decline, nearly 90% of its historic occurrences are extinct, leaving only 50 natural sites remaining worldwide (Cross 2012). This critically endangered plant, with its novel aquatic carnivorous habit, has long been venerated by carnivorous plant hobbyists. Consequently, plants have been propagated and successfully introduced into many waterbodies in countries where it is not native. Deliberate introductions (or so-called assisted migration/colonization events) have become a more recent conservation tool for Aldrovanda vesiculosa (Adamec 2005; Cross 2012). About 30 artificial sites are known in Europe, Asia, and North America. Introductions (from Japanese sources) into the eastern United States first established the species in Virginia, and then subsequently into New Jersey and New York (Lamont et al. 2013). We report here on an assisted colonization effort, via a known carnivorous plant hobbyist, that led to an established population of Aldrovanda vesiculosa var. vesiculosa in southern New Hampshire. This represents the first documented occurrence of the species in New England and is its most northern station in North America. Plants of Japanese origin were deposited by the aforementioned hobbyist into a waterbody in Pelham, New Hampshire, in ca. 2010 in the hopes of establishing another locality for this imperiled species. The initial visit to the New Hampshire site in July 2017 confirmed the population survived, but in summer 2018 plants were not located. Plants were again observed in 2019 (Matthew Charpentier, Oxbow Associates Inc., pers. comm.).

Urban fungal biodiversity is understudied and there are no published studies focusing on the diversity of Boletales in New York City. Many Boletales are known to form mycorrhizal associations, which are important to plant and ecosystem health. In this study, MyCoPortal, a public database of fungarium collections, was queried to generate a species list of all Boletales collected from New York City over the past 123 years. Overall, 89 species in 12 families of Boletales were found across the five boroughs of the city, though a number of species have not been re-collected in over a century. The species list illustrates the previously overlooked diversity of Boletales in New York City and can be used to direct future efforts to study these fungi in urban ecosystems.","PeriodicalId":54454,"journal":{"name":"Rhodora","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43942038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The three primary forest communities discussed here are classified by their dominant tree species: ridges with eastern red cedar, ravines with eastern hemlock, and acidic, boreal swamps with black gum. The old-growth eastern red cedars occur throughout the Metacomet traprock ridges, which run north to south along central Connecticut. The old-growth eastern hemlocks are found in remote, steep ravines mostly within the Litchfield Hills and Connecticut's northwest corner. Isolated acidic boreal black gum/red spruce swamps are concentrated in high-altitude, shallow basins in the Litchfield Hills and the Quiet Corner (Northeastern Connecticut).","PeriodicalId":54454,"journal":{"name":"Rhodora","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46011702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The alga was initially collected during May 2018 from the Outer Sunken Rocks area of Hampton, New Hampshire (42°53.657′N, 70°47.177′W) by divers from Normandeau Associates, Inc. who were conducting destructive biomass studies of attached seaweeds at a depth of ca. 12.2 m (40 ft). The location represents one of their long-term study sites (Station B19) utilized during environmental monitoring of the Seabrook Power Station and the contiguous Hampton-Seabrook area (Normandeau Associates, Inc. 2007). The station also represents a study site (i.e., HB4) previously evaluated by Mathieson and Fralick (1972) in their detailed floristic studies of algal vegetation of the Hampton-Seabrook Estuary and the open coast of Hampton, New Hampshire, where the alga was not previously found. Recently (2020), Normandeau divers also found A. pectinatum at two other Hampton-Seabrook study sites (i.e., B31 and B35) during multiple sampling periods.","PeriodicalId":54454,"journal":{"name":"Rhodora","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48357888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
