Japanese knotweed, Fallopia japonica is one of the most troublesome invasive alien plant in Europe and North America. In 2012 we started monitoring for possible indigenous natural enemies of Japanese knotweed in Slovenia. In Zgornji Log, near Litija (46°4′38.09″N, 14°49′31.65″E; 245 m) on the river ...

Smaller, yellowish brown areas of diseased grass [Zoysia matrella (L) Merr.] were observed scattered in a home garden lawn in Kandy District (Central Province) of Sri Lanka. There was also a ring of brown grass and whitish aerial mycelium grown in between foliage and runners, boarding a greenish...

The present work consisted of presenting some of the main results about the use of taper models in different native and exotic species, except for pinus and Eucalyptus, in the different regions of Brazil. Many works were carried out, mainly, in the South, North, Southeast and Center-West....

Description of the subject. The geographic distributions of a species, be it native or alien, is expected to be limited at some point by environmental conditions. In this situation, a range edge equilibrium (REE) takes place, i.e., populations occurring beyond the edge have a growth rate reduced...

Several permanent populations of Thrips hawiiensis (Morgan) were discovered outdoors for the first time in 2015, in different sites in Italy. The species widely distributed and common in tropical countries is now recorded from three European countries: France, Spain and Italy. It is a phytophagous...

Anoplophora glabripennis, Anoplophora chinensis and Psacothea hilaris hilaris are three invasive exotic longhorn species (Coleoptera Cerambycidae) threatening native broadleaf trees in Europe and North America. Field studies on invasive species are somewhat difficult in the areas of introduction...

The nearctic moth Acontia candefacta (Lepidoptera Noctuidae) is expanding its range in Europe. The species is considered a successful agent for biological control of Ambrosia artemisiifolia (Asterales Asteraceae), a weed whose pollen causes allergies in humans. A few additional findings of the moth ...

The knowledge of the endemic drosophilid assemblage is a useful reference to study population dynamics when new species are introduced in a geographical area. The introduction of invasive species can change the structure of the drosophilid community; hence, the distribution data for endemic species ...

To reduce the harms of plant invasion, the risk assessment for biological invasion of exotic species (including intentionally introduced species and accidentally introduced species) is particularly important. Through data review, investigation research and expert consultation, risk assessment...

Introduction of invasive species is a major threat to freshwater biodiversity. Topmouth gudgeon, pumpkinseed sunfish and black bullhead catfish have been recognised as highly invasive fish species in Croatia. However, their diet in allochthonous habitats are generally still poorly understood, and...
