“…Because the Canadian material has yet to be analysed genetically we refer to the species by the common name Himalayan blackberry in this account. Some material referred to as Himalayan blackberry appears to be a clonal descendent of microspecies R. armeniacus, as hypothesized by Bailey (1923Bailey ( , 1945 and confirmed by recent genetic analysis of plants from Washington, Oregon and California (Clark et al 2013). Clark et al (2013) also found some material in the same regions corresponding to R. anglocandicans A. Newton.…”

“…Himalayan blackberry also has a broader infloresence than either R. vestitus Weihe (found in Washington and Oregon) or R. ulmifolius (Alice et al in press). Recent advances in distinguishing various clones of the R. fruticosus aggregate have been made employing molecular techniques, sometimes overturning existing distinctions based on morphological characteristics (Kraft and Nybom 1995;Evans and Weber 2003;Clark et al 2013).…”

M. 2015. The Biology of Canadian Weeds. 154. Himalayan blackberry. Can. J. Plant Sci. 95: 557Á570. Himalayan blackberry, an invasive weed in Canada, is particularly problematic in southwestern British Columbia. Isolated occurrences have also been recorded in Ontario. The nomenclature of this species has been under review recently; Rubus armeniacus Focke, R. discolor Weihe & Nees, and R. bifrons Vest have been frequently applied, as well as R. procerus auct. Non P. Muell. Ex Genev, Rubus praecox Bertol., R. vestitus Weihe and others. Himalayan blackberry microspecies in North America are within the species aggregate R. fruticosus L. Because the Canadian material has yet to be analysed genetically we refer to the species by the common name Himalayan blackberry in this account. Because of its vigorous growth in temperate, moist environments, it has become a problem weed in the Pacific Northwest, where it outcompetes native plant species by shading. It reproduces by seeds and vegetatively, forming dense thickets. Although humans value blackberries harvested from Himalayan blackberry and the plant also provides habitat and food for wildlife, management to prevent excessive growth is recommended. Nesting songbirds preferred more diverse, ''natural'' forest types over Himalayan blackberry-dominated thickets in southwestern British Columbia. Chopping, cutting, mowing or browsing by goats and/or herbicide application are effective management strategies but require diligence to prevent vegetative re-growth. A leaf fungal rust, Phragmidium violaceum (Schultz) Winter, has recently become a major pathogen of Himalayan blackberry in Oregon, and was found to occur in British Columbia in 2008.Key words: Himalayan blackberry, Rubus armeniacus, Rubus bifrons, Rubus fruticosus agg., Rosaceae, weed biology Gaire, R., Astley, C., Upadhyaya, M.

“…This species is indigenous in the Caucasus and introduced in central Europe around 1800 . Rubus armeniacus (sometimes referred to as R. praecox, which is a different species) is worldwide considered an invasive species, threatening natural ecosystems in several temperate regions (Caplan & Yeakley 2006;Pfeiffer & Ortiz 2007;Astley 2010;Caplan & Yeakley 2010;Richardson & Rejmánek 2011;Clark et al 2013). Figure 8.3 shows the distribution of this species in the Netherlands in the map grid cells where other Rubus species are lacking.…”

Nighttime transpiration is a substantial portion of ecosystem water budgets, but few studies compare water use of closely related co-occurring species in a phylogenetic context. Nighttime transpiration can range up to 69% of daytime rates and vary between species, ecosystem, and functional type. We examined leaf-level daytime and nighttime gas exchange of five species of the genus Rubus co-occurring in the Pacific Northwest of western North America in a greenhouse common garden. Contrary to expectations, nighttime transpiration was not correlated to daytime water use. Nighttime transpiration showed pronounced phylogenetic signals, but the proportion of variation explained by different phylogenetic groupings varied across datasets. Leaf osmotic water potential, water potential at turgor loss point, stomatal size, and specific leaf area were correlated with phylogeny but did not readily explain variation in nighttime transpiration. Patterns in interspecific variation as well as a disconnect between rates of daytime and nighttime transpiration suggest that variation in nighttime water use may be at least partly driven by genetic factors independent of those that control daytime water use. Future work with co-occurring congeneric systems is needed to establish the generality of these results and may help determine the mechanism driving interspecific variation in nighttime water use.
