This preliminary exploration of marine lichenized fungi (lichens) as bioindicators of water pollution examined the distribution of intertidal lichen communities in the Boston Harbor Islands National Recreation Area with respect to recorded pollution throughout the harbor. We found significant negative associations between pollution measurements and the health of the lichen community based on cover and species richness. We also observed significant differences in species composition between areas of higher pollution and areas of lower pollution, though not enough data are available to establish the pollution sensitivity or tolerance of individual species. We note that difficulties in the collection and identification of marine lichens hamper efforts to use them broadly as bioindicators. This study suggests that marine lichens could prove useful as bioindicators, but more research is needed to understand the differential effects of pollution on individual species as well as to establish practical procedures both for quantifying marine lichen community health and for widespread bioindication using marine lichens. Finally, one species collected during this study, Verrucaria ceuthocarpa, represents a first report for the Boston Harbor Islands National Recreation Area.","PeriodicalId":54454,"journal":{"name":"Rhodora","volume":"122 1","pages":"251 - 273"},"PeriodicalIF":0.2,"publicationDate":"2022-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44114826","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}

Stephenson","doi":"10.3119/20-20","DOIUrl":"https://doi.org/10.3119/20-20","url":null,"abstract":"ABSTRACT. Crowley's Ridge is a low, narrow, eroded ridge that rises above the uniformly flat alluvial floodplain in the northeastern quadrat of Arkansas. The ridge is geologically unique because it consists largely of wind-blown soil (loess) deposited during the late Pleistocene. During June 2008, quantitative data on the composition and structure of all strata of forest vegetation were collected from ten 0.1 ha plots at two general localities on the southern portion of Crowley's Ridge. Acer saccharum (sugar maple) was the leading dominant in the large/ medium-sized tree stratum, followed by Quercus rubra (northern red oak), Q. velutina (black oak) and Q. stellata (post oak), all with importance value indices > 10. Other species present included Carya alba (mockernut hickory), Fraxinus americana (white ash), Fagus grandifolia (American beech), and Liriodendron tulipifera (tulip-tree). Except for post oak, these trees tend to be characteristic of the classic Mixed Mesophytic Forest Region of the southeastern United States. In six of the 10 plots, the combined importance values of species typically associated with mixed mesophytic forests represented 84% to 100% of the large/ medium-sized tree stratum. Twenty-three different species were recorded in this stratum, a level of diversity that is comparable to a mixed mesophytic forest. As such, the data presented herein indicate that at least some forests on Crowley's Ridge apparently represent the westernmost examples of this forest type.","PeriodicalId":54454,"journal":{"name":"Rhodora","volume":"122 1","pages":"321 - 331"},"PeriodicalIF":0.2,"publicationDate":"2022-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44838430","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}
