Semi-natural grasslands invaded by the legume Lupinus polyphyllus need introduction of target species in order to promote highly endangered native plant communities. However, which techniques are best suited achieve both invader control and at same time? Few studies have investigated restoration that support communities mountain meadows simultaneously. We employed seed bank activation green hay...
Abstract Mulching, cutting of the vegetation without plant biomass removal, is a common alternative to mowing. The aim our study was find out if mulching forest meadows at different time points affects cavity-nesting bees and wasps. We exposed trap nests for wasps 24 in south-western Germany over 2 years applied four experimental treatments with six replicates: (i) June, (ii) September, (iii) J...
Ground-ivy ( Glechoma hederacea L.) is a widespread stoloniferous plant that grows in several ecologically diverse habitats: the open, at forest edge, and understorey. The vegetation of ground-ivy habitats was studied NE Slovenia terms floristic richness diversity, biological spectrum, phytogeography syntaxonomy. We identified five clusters distinct with occurrence ground-ivy, differentiated ac...
Climate change models for many ecosystems predict more extreme climatic events in the future, including exacerbated drought conditions. Here we assess the effects of drought by quantifying temporal variation in community composition of a complex montane meadow landscape characterized by a hydrological gradient. The meadows occur in two regions of the Greater Yellowstone Ecosystem (Gallatin and ...
The meiofauna from seagrass meadows in the western sector of the Gulf of Batabanó, Cuba were studied to describe the spatial and temporal variations in community structure. Replicated cores were taken in three locations (arranged in m- and km-scales) and in two seasons (dry and wet). The meiofauna (metazoans between 500 and 45 microm) were identified to major taxa. Temporal changes in the meiof...
Garrison creeping foxtail can increase the forage yield of wet meadows. However, tillage can be problematic on heavy-textured soils and thick sod mats often associated with wet meadows. This study examined the potential of establishing Garrison with the use of herbicides and no-till planting. Garrison was no-till drilled into a wet meadow using herbicide control of existing vegetation in the en...
Vascular plants serve as target species for the evaluation of restoration success as they account for most of the plant species diversity and vegetation cover. Although bryophytes contribute considerably to the species diversity of meadows, they are rarely addressed in restoration projects. This project is a first step toward making recommendations for including mosses in alluvial floodplain re...
Wetland ecosystems are highly productive and valued for numerous reasons including wildlife habitat, biodiversity, water quantity quality, human uses. Grazing livestock on wet grasslands can sometimes be controversial due the humidity of but other hand, it plays an important role in grassland preservation. Therefore, we evaluated impact Polish white-backed cattle grazing changes vegetation (13 ...
The Amazon catchment is the largest river basin on earth, and up to 30% of its waters flow across floodplains. In open waters, floating plants known as meadows abound. They can act vectors dispersal for their associated fauna and, therefore, be important spatial structure communities. Here, we focus amphibian diversity in Amazonian over large scales. We recorded 50 species 57 sites, covering ar...
