Forty years in species knowledge. A case study of the genus Epilobium
... Possibly due to this circumstance, the weed compendium of Lithuania (čiubeRkiS & vilkoniS, 2013), consisting of 234 species, does not include the members of the Epilobium genus. Therefore, the frequency and distribution of (Matulevičiūtė, 2007(Matulevičiūtė, , 2010. The information about the survival of willowherb plants after herbicide application in the orchards (V. ...
... The important role of the recovery of vegetation after the herbicide application in the study was demonstrated by E. parviflorum and E. tetragonum as well. High abundance and frequency of E. parviflorum plants contradict to the peculiarities of distribution of this species: it is not considered as frequent either in Lithuania (FataRe et al., 1996;Matulevičiūtė, 2010) or in neighbouring Latvia and Estonia (FataRe et al., 1996). The abundance of hoary willowherb in the study area was determined by favourable environmental conditions since this species is restricted to nutrient and carbonates rich, loamy or clayey soils and tolerates partial shade (oBeRdoRFeR et al., 1994). ...
... Interesting is the fact that five decades ago, E. tetragonum was sparse in the northern part of its distribution area (meusel et al., 1965) and at the end of the 20 th century this species was very rare in the Baltic countries (FataRe et al., 1996), though in the last decade it has become frequent, while not equally distributed in Lithuania (Matulevičiūtė, 2010). Based on my personal observations, I can affirm the changes in the frequency as well as in the abundance of this species and its spread over broad range of natural, seminatural and anthropogenic habitats of Lithuania. ...
Several species of willowherb (Epilobium) are considered as agricultural weeds and their prevalence has become an increasing problem in agriculture. The aim of this study was to investigate the role of willowherb plants in the initial stage of vegetation succession a year after the use of glyphosate. The study was based on the examination of thirteen willowherb specimens collected in the apple orchard of 0.2 ha area in August 2008, one month after glyphosate treatment, and vegetation field investigations in the same orchard in July 2009. The coverage of herb layer, the abundance and life stages of Epilobium plants in twenty plots of 1 m
