Incorporating annual forages into an integrated livestock-crop management system may help prolong the grazing season for most livestock-management systems in the Upper Great Plains. The objectives of this study were to determine (1) the differences in sheep performance ADG (average daily gain)...

Japanese knotweed is an invasive plant brought to the UK in the mid 19th Century as a highly prized ornamental. Since its introduction it has caused serious problems in many areas. These range from impeding drainage and displacing natural flora and fauna to causing structural damage and an...

The history of spread and habitat preferences during invasion of four alien species of Lepidium in Romania, namely L. densiflorum, L. oblongum, L. sativum, and L. virginicum are presented in this paper. The floristic records of these species, collected between 1816 and 2013, were used in the study. ...

Adults of the nocturnal, cricket-parasitizing wasp Rhopalosoma nearcticum flew in Dyke Marsh Wildlife Preserve (DMWP) from late June through late September, based on a 2-year, Malaise-trap sample of 617 individuals from three habitats. These wasps were significantly more abundant in the floodplain...

The Philippines has high diversity of ants but many species are still undescribed. In this study, species diversity of ants was determined in karst limestone habitats in selected areas in Davao Oriental, Kitaotao, Bukidnon and Valencia City, Bukidnon using a combination of quadrat, hand collection, ...

We studied genetic diversity within and among populations of warty cabbage (Bunias orientalis L.), which is an alien species in Lithuania and other Baltic countries. In Lithuania, this weed colonises two main types of habitats: railway/roadsides and meadows on riversides. The aim of this study was...
