Fine-grain beta diversity in Palaearctic open vegetation: variability within and between biomes and vegetation types

2021

Aims: To quantify how fine-grain (within-plot) beta diversity differs among biomes and vegetation types. Study area: Palaearctic biogeographic realm. Methods: We extracted 4,654 nested-plot series with at least four different grain sizes between 0.0001 m² and 1,024 m² from the GrassPlot database spanning broad geographic and ecological gradients. Next, we calculated the slope parameter (z-value) of the power-law species–area relationship (SAR) to use as a measure of multiplicative beta diversity. We did this separately for vascular plants, bryophytes and lichens and for the three groups combined (complete vegetation). We then tested whether z-values differed between biomes, ecological-physi…

A miniature world in decline. European Red List of Mosses, Liverworts and Hornworts

2019

AimThis Red List is a summary of the conservation status of the European species of mosses, liverworts and hornworts, collectively known as bryophytes, evaluated according to IUCN’s Guidelines for Application of IUCN Red List Criteria at Regional Level. It provides the first comprehensive, region-wide assessment of bryophytes and it identifies those species that are threatened with extinction at a European level, so that appropriate policy measures and conservation actions, based on the best available evidence, can be taken to improve their status.ScopeAll bryophytes native to or naturalised in Europe (a total of 1,817 species), have been included in this Red List. In Europe, 1,796 species …

Four Remarkable Additions to the Biodiversity of Chinese Mosses

2022

Four species of moss genus Schistidium are reported for the first time from China. All of them have been found in the Xinjiang Uyghur Autonomous Region. Ecological and distributional details of the newly recorded species are provided and their local distribution is mapped. Photographs of the species are attached. Checklist of Schistidium species and identifying key are added. Considering the present records, Schistidium consists of 15 species in China.

Agarose/κ-carrageenan-based hydrogel film enriched with natural plant extracts for the treatment of cutaneous wounds.

2020

Abstract Hydrogels for complex and chronic wound dressings must be conformable, absorb and retain wound exudates and maintain hydration. They can incorporate and release bioactive molecules that can accelerate the healing process. Wound dressings have to be in contact with the wound and epidermis, even for long periods, without causing adverse effects. Hydrogel dressing formulations based on biopolymers derived from terrestrial or marine flora can be relatively inexpensive and well tolerated. In the present article hydrogel films composed by agarose (1.0 wt%), κ-carrageenan at three different concentrations (0.5, 1.0 and 1.5 wt%) and glycerol (3.0 wt%) were prepared without recourse to cros…

Scale-dependent plant diversity in Palaearctic grasslands: a comparative overview

2016

Here we present an extensive overview of plant diversity values in Palaearctic grasslands for seven standard grain sizes from 0.0001 to 100 m². The data originate from 20 studies, including the Field Workshops of the Eurasian Dry Grassland Group (EDGG), ranging geographically from Spain in the west to Siberia in the east, from Sicily in the south to Estonia in the north and from the sea coast up to 3100 m a.s.l. The majority of data is from dry grasslands (Festuco-Brometea, Koelerio-Corynephoretea, Cleistogenetea squarrosae), but there are also some mesic, wet, saline, acidic, alpine and Mediterranean grasslands included. Among others, we compiled data from 1795 1-m², 1109 10-m² and 338 100…

Bryophytes collected during the 12th “Iter Mediterraneum” (Tunisia, 24 March – 4 April, 2014). First contribution

2015

Part of the bryophytes collected during Iter Mediterraneum XII is listed. Some noteworthy species were found: Dicranella howei, had so far been recorded only doubtfully from Tunisia; Funaria hygrometrica, Grimmia laevigata, Grimmia trichophylla, Imbribryum alpinum, Pogonatum nanum, Rhynchostegium riparioides, Scleropodium touretii, Scorpiurium circinatum, Thamnobryum alopecurum, Timmiella barbuloides, Tortella squarrosa, Tortula muralis and Tortula vahliana, had not been reported from that country for more than half a century.

Project for a Red List and country assessment of Italian Bryophytes.

2016

Italy represents a biodiversity hot spot in the Mediterranean area. To monitor and defend its great “natural patrimony”, coherently with the Europe Strategy for Plant Conservation (EPCS, 2002) and the EU Biodiversity Strategy for 2020 (2011), the Italian Ministry of Environment, land and sea protection supported a national project to compile the first Red List of Italian flora (Rossi et al. 2013) according to IUCN criteria (2001), coordinated by the Italian Botanical Society. For Italian bryophytes the first red lists were compiled by Cortini Pedrotti & Aleffi (1992) for mosses and Aleffi & Schumacker (1995) for liverworts and hornworts. To update these lists the Working Group for B…

Materiały do brioflory rezerwatu przyrody Boczki (Puszcza Romincka)

2017

The results of bryological investigations from the “Boczki” nature reserve, located in Puszcza Romincka Forest, are presented. The reserve was established in 1974 for protection well preserved forest communities characteristic of the Romincka Primeval Forest. 154 bryophyte species were recorded – 37 liverworts and 117 mosses, including 37 unpublished species from the Puszcza Romincka Forest. In respect of frequency the main group make rare species – 29.2%, the least numerous were frequent – 21.4%. Terrestrial and epixylic habitats were the richest – refer 98 and 85 species respectively. Significant were groups of protected (47) and endangered (14) species. There is also a large share of bry…
