Nowadays, one of the most effective seed dispersal vectors are humans. The key our efficiency is the rapidly growing rate of global transport, trade and tourism, which enables us to move more and more easily and quickly between distant biogeographical regions, and even between continents. Based on the results of studies so far, nearly 500 species have been registered to be able to spread on clothing, and most of thes are weed and invasive species that cause serious conservation problems, especially in the isolated habitats.
Community science based monitoring of invasive mammal and bird species of Hungary has begun in a cooperation between the Institute for Wildlife Management and Nature Conservation of Hungarian University of Agriculture and Life Sciences (MATE) and the Institute of Ecology and Botany, Centre for Ecological Research.
This year, the Eurasian Grassland Conference was held in Szarvas, organized by the Lendület Seed Ecology Research Group of the HUN-REN Ecological Research Centre and the Körös-Maros National Park Directorate, where several research groups of the Invasion Biology Division presented their latest results.
Plant invasion and habitat fragmentation have adverse effects on biodiversity in almost all ecosystems. Our research explored the direct and indirect effects of common milkweed (Asclepias syriaca) invasion on plant and arthropod biodiversity.
Citizen science and mosquito research: the relationship between urbanisation and invasive mosquitoes in Hungary
Urbanisation can contribute significantly to the spread of invasive mosquito species and the diseases they spread.
Invasions of alien species are a major cause of biodiversity loss, threatening both natural and human-managed ecosystems. Ecological restoration of habitats is key to controlling invasion, and seeding restored habitats with appropriate species can increase their resistance to invasion. In this research, the Centre for Ecological Research’s Restoration Ecology Research Group sought to answer the […]
Roadside verges are a key corridor for the spread of invasive species and are often considered as invasion hotspots. Invasive plant species are a source of serious problems for both road managers and conservationists. Grassland restoration with seeds of native grassland plant species is a promising solution to control these species. In a recent publication, […]
Ecological effects of an intensively spreading native species: evaluation of the beavers’ foraging strategy
The Eurasian beaver is a native species with community interest in the European Union. The species was previously extinct in Hungary, but today it is spreading intensively in the country, recolonising its former habitats. The selective foraging activity of the beaver can induce significant changes in the woody vegetation along streams and canals, influencing the […]
Timing and the right quantity and composition of the seed mixture are key in seeded grassland restoration. Research by the Centre for Ecological Research has sought to answer the question of how to time the sowing of seed mix components to best establish grassland species and effectively control invasive species and weed. Grasses are usually […]
Escape from the gardens: one of our favourite ornamental plants is becoming an invasive species before our eyes
Ornamental plants are introduced to new habitats when they are planted in gardens, where the maintaince creates the suitable conditions for them. Later, in natural habitats, they can easily occupy open niches by escaping from gardens and become invasive. This is the path taken by the great blanketflower, whose ecological effects have been studied by […]
Invasive plant species have a negative impact on local fauna, such as pollinating insects, by transforming vegetation and decreasing floral resources. In three recent studies, researchers from the Centre for Ecological Research and Babeş-Bolyai University have investigated the effects of twelve herbaceous invasive plant species with different characteristics on vegetation (Fenesi et al. 2023), pollinator […]
In a new study, the Mosquito Monitor Group has used a model-based approach to demonstrate that so-called “citizen science” data collected with the public’s participation can be used to draw scientific conclusions. By “citizen science” or “community science” we mean scientific research that involves society in shorter or longer scientific projects, and in this way […]
Short-term effects of control of the invasive plant (Asclepias syriaca L.): secondary invasion of neophyte plants instead of regeneration of native species. In this study, we investigated the effects of the common milkweed, a perennial, vegetatively well-spreading invasive plant species from North America, on the main soil properties and vegetation composition in a field experiment […]
The raccoon (Procyon lotor) is an alien species that is widespread in mainland Europe (e.g., France, Belgium, Germany, Poland). Populations originated from escaped pets and introductions. The raccoon is already confirmed in the fauna of Hungary. The spread of this invasive species from North America could threaten native ecosystems. For this reason, the 1st European […]
