Three central issues, addressed in this introduction, are: (i) Extreme habitat conditions generate species-poor vegetation. Samples of such vegetation shaped by dominant plants may be difficult to classify at and beyond the level of association. (ii) Halophytic vegetation is phenologically heterogeneous, often with late-flowering and late-fruiting matrix species of the chenopod family. Multiple sampling is recommendable for fieldwork, moreover critical re-assessment of historical saltmarsh plot data, especially if collected early in the year. (iii) Vegetation classification and ecology make use of, and depend on, the results of plant taxonomic and phylogenetic research. Yet in turn, vegetation classification may be supportive of plant taxonomy if cryptic and newly described or circumscribed taxa prove to be ecologically, phytosociologically, phytogeographically or phenologically distinct, and likewise if they are not.","PeriodicalId":54607,"journal":{"name":"Phytocoenologia","volume":"46 1","pages":"333-338"},"PeriodicalIF":1.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1127/phyto/2016/0174","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63697284","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}

{"title":"Vegetation Database of the Okavango Basin","authors":"R. Revermann, Amândio Gomes, F. M. Gonçalves, Johannes Wallenfang, T. Hoche, N. Jürgens, M. Finckh","doi":"10.1127/PHYTO/2016/0103","DOIUrl":"https://doi.org/10.1127/PHYTO/2016/0103","url":null,"abstract":"The Okavango river basin, located in southern Africa and shared by the countries Angola, Namibia and Botswana, harbours large extents of natural and semi-natural ecosystems. At the same time, it is a hot spot of accelerating land use change causing transformation of vegetation in many regions of the basin. However, knowledge on vegetation composition and plant diversity is very limited, especially of the upper reaches of the river in Angola. The Future Okavango (TFO) project aimed at closing this gap and initiated a plot-based vegetation survey in 2011. Here we present the resulting Vegetation Database of the Okavango Basin (GIVD ID: AF-00-009; http://www.givd.info/ID/AF-00-009). We used unsupervised classification of MODIS land surface phenology metrics to identify existing major vegetation units forming the basis of a random, stratified sampling design. However, sampling was largely constrained by limited access and the hazard of land mines, a legacy of the civil war in Angola. Furthermore, detailed sampling on four local study sites of 100 km2 representing the different macro-ecosystems of the basin was carried out. Vegetation plots followed a nested design of a 100-m2 plot resting in the centre of a 1,000-m2 plot. In every plot, we recorded all vascular plant species with their estimated, projected cover, vegetation height, cover of vegetation strata, topography, and intensity of land use activities. Furthermore, soil samples were taken, and diameters of trees measured. Currently, the database has a focus on terrestrial vegetation, including Miombo woodlands and forests, geoxylic grasslands, Baikiaea-Burkea woodlands, and Colophospermum mopane woodlands. However, the database also includes plots of the tropical wetlands and peat bogs of the Angolan Central Plateau. The specific vegetation of the Okavango Delta is not yet included. The collected vegetation data will feed into a phytosociological classification and ecological modelling applications. Another objective is the identification of successional pathways after disturbance through land use. Ultimately, it will provide the basis for a vegetation map of the Okavango region.","PeriodicalId":54607,"journal":{"name":"Phytocoenologia","volume":"46 1","pages":"103-104"},"PeriodicalIF":1.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1127/PHYTO/2016/0103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63696709","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}

It also proposes solutions to a number of issues that cause conflict between the classical Central European concept of the Molinio-Arrhenatheretea class and its traditional syntaxonomy in the former USSR. Location: Forest and forest steppe zones of Ukraine. Methods: I analysed 2,105 relevés originally assigned to the Molinio-Arrhenatheretea class using the European Expert System and Kmeans clustering. The units were evaluated for quality and internal homogeneity using Sharpness index and Average Whittaker beta-diversity. I determined the diagnostic species of the vegetation units using calculations of their fidelity based on a phi-coefficient. The environmental assessment of the units follows the Didukh indicator values. Results: I interpreted the resulting vegetation units as alliances of the Braun-Blanquet system (Agrostion vinealis, Arrhenatherion elatioris, Cynosurion cristati, Deschampsion cespitosae, Molinion caeruleae, Potentillion anserinae and Calthion palustris) based on a complex of diagnostic species. I also analysed the distribution of the communities of the identified alliances in the study area, revealing their ecological features. Conclusions: The use of modern phytosociological methods in this study to analyse geobotanical data collected over a long period and a large area covering the whole range of the Molinio-Arrhenatheretea class in the country, clarified a number of controversial issues previously related to the lack of coordination between the Central and Eastern European phytosociology.","PeriodicalId":54607,"journal":{"name":"Phytocoenologia","volume":"46 1","pages":"241-256"},"PeriodicalIF":1.0,"publicationDate":"2016-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1127/PHYTO/2016/0083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63696332","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}

Bolpagni, A. Piotti","doi":"10.1127/0340-269X/2014/0044","DOIUrl":"https://doi.org/10.1127/0340-269X/2014/0044","url":null,"abstract":"In the European plains, up to eighty percent of riverine wetlands have been lost due to alteration of hydrological regime and catchment exploitation. This condition is expected to be further negatively exacerbated by climate change. To better understand the observed change in distribution patterns of hydro-hygrophilous vegetation in temperate and Mediterranean floodplains, a vegetation survey was conducted within the lower Oglio River reach in Northern Italy. This river is a mid-size, altered and nutrient-rich left tributary of the Po River. During the 2008 growing season, a total of 60 marginal aquatic habitats were investigated. Overall, 37 vegetation communities were detected, showing a clear predominance of hygrophilous herbaceous plant communities both in terms of representativeness (55.1%) and diversity (54.1%) with respect to woody (22.9% and 10.8%, respectively), and obligate aquatic vegetation (22.0% and 35.1%, respectively). Our main findings were (1) the widespread presence of highly opportunistic, non-native and invasive hygrophilous plant communities (largely dominated by Amorpha fruticosa, Phragmites australis s.l., Amaranthus spp., Bidens spp., and Cyperus spp.), and (2) the limited distribution of hydrophyte vegetation usually dominated by pleustophytes (e.g., Spirodela polyrhiza and Lemna spp.). The present study confirms the dominance of secondary plant communities characterized by the widespread presence of alien species in lowland over-exploited riverscapes, coupled with a low local representativeness of native willow (Salix alba, S. cinerea) communities and anchored macrophyte (batrachid, ceratophyllid, elodeid, myriophyllid) meadows. Total vegetation diversity is consistent with previous studies in similar ecological contexts; on the other hand, at the site scale, the diversity values were extremely low. This is especially true for the aquatic vegetation, and can be related to the high water turbidity and chlorophyll-a concentrations that prevent the establishment and colonization of submerged and rooted hydrophytes. Consequently, we stress the need for metabolic and biogeochemical indicators to assess the actual trophic status of lowland wetlands in order to clarify their potential to be restored.","PeriodicalId":54607,"journal":{"name":"Phytocoenologia","volume":"45 1","pages":"69-84"},"PeriodicalIF":1.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1127/0340-269X/2014/0044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63853483","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}
