The genus Thalictrum (Ranunculaceae), commonly known as meadow rue, comprises 200 species throughout the world and there are 25 taxa growing in India. While revising the genus in India, we came across a new species collected in Nainital in the Uttarakhand Himalaya. The new species, Thalictrum nainitalense, is differentiated from its closely allied species T. punduanum in its habitat preference for

Early vegetation succession on gravel bars of Czech Carpathian streams Folia Geobot. (IF 1.242) Pub Date : 2018-07-03 Veronika Kalníková; Kryštof Chytrý; Milan Chytrý
Rivers with a natural flooding regime and gravel accumulations are an important natural habitat endangered by regulations and other types of human impact. Succession after disturbances by floods creates a mosaic of different vegetation types, some of them containing rare specialist species. We studied vegetation succession and changes in plant diversity on river gravel bars of four streams in the Western

Glacial-relict symptoms in the Western Carpathian flora Folia Geobot. (IF 1.242) Pub Date : 2018-05-30 Daniel Dítě; Michal Hájek; Ivana Svitková; Alica Košuthová; Rudolf Šoltés; Ján Kliment
Glacial relicts have been regionally more common in glacial than in recent times. A rigorous assessment of which species are indeed glacial relicts is extremely difficult because direct evidence is untraceable or equivocal for many species. We aimed to identify species of the Western Carpathian flora (vascular plants, bryophytes and terrestrial lichens) that display apparent biogeographical and ecological

Distribution of C4 plants in sand habitats of different climatic regions Folia Geobot. (IF 1.242) Pub Date : 2018-05-27 Parastoo Mahdavi; Erwin Bergmeier
Sand dunes of warm regions provide suitable habitats for C4 plants because of their water and nitrogen use efficiency under high temperature and their high tolerance to ecological stress such as salinity, aridity and disturbance. We studied the distribution patterns of C4 plant species in five habitat types of sand dune ecosystems in three climatic regions (Mediterranean, Irano-Turanian and Hyrcanian)

Role of infrastructure and other environmental factors affecting the distribution of alien plants in the Tatra Mts Folia Geobot. (IF 1.242) Pub Date : 2018-05-25 Jana Medvecká; Mária Zaliberová; Jana Májeková; Dušan Senko; Ivan Jarolímek
Alien plants, although usually rare in mountain habitats, can significantly impact native species diversity. The aim of this study was to analyse patterns of alien plant distribution in the Tatra Mts (Slovakia), focusing primarily on comparison of various transportation routes as a conduit for the spread of alien plants. We collected data on transects along: (i) railways, (ii) paved roads with unlimited

Long-term hay meadow management maintains the target community despite local-scale species turnover Folia Geobot. (IF 1.242) Pub Date : 2018-05-22 Elizabeth R. Sullivan; Ian Powell; Paul A. Ashton
Hay meadows, which are managed using a low-intensity regime, are characterized by highly diverse vegetation but have declined significantly since the mid twentieth century. Remaining species-rich meadows are often protected by statutory designations and conservation management agreements. However, long-term studies of change in the composition of meadow vegetation, and investigations of the success

Relict occurrences of boreal brown-moss quaking rich fens in the Carpathians and adjacent territories Folia Geobot. (IF 1.242) Pub Date : 2018-05-18 Tomáš Peterka; Michal Hájek; Daniel Dítě; Petra Hájková; Salza Palpurina; Irina Goia; Vít Grulich; Veronika Kalníková; Zuzana Plesková; Anna Šímová; Táňa Štechová
Quaking rich fens dominated by boreal semi-aquatic brown-mosses such as Scorpidium scorpioides and Calliergon trifarium are extremely rare in the Carpathians. These fens harbour endangered species persisting at few localities in the region. However, their phytosociological classification has not been sufficiently solved yet, because they lack Sphagnum species as well as calcicole species characteristic

Plant species composition shifts in the Tatra Mts as a response to environmental change: a resurvey study after 90 years Folia Geobot. (IF 1.242) Pub Date : 2018-03-19 Patryk Czortek; Jutta Kapfer; Anna Delimat; Amy Elizabeth Eycott; John-Arvid Grytnes; Anna Orczewska; Halina Ratyńska; Antoni Zięba; Bogdan Jaroszewicz
Mountain vegetation is often considered highly sensitive to climate and land-use changes due to steep environmental gradients determining local plant species composition. In this study we present plant species compositional shifts in the Tatra Mts over the past 90 years and discuss the potential drivers of the changes observed. Using historical vegetation studies of the region from 1927, we resurveyed
