To date, 18 species of the algal genus Lobophora (Dictyotales, Phaeophyceae) have been reported for Greater Caribbean Sea. Nevertheless, only 2 recorded marine flora Cuba, variegata and canariensis (as Aglaozonia ). update knowledge about this in an exhaustive morphological study was performed using macroalgae collected from Western Cuba: Ecological Reserve Los Pretiles (Pinar del Río Province;...

Sediment accretion (burial) and nutrient enrichment occur concurrently in lacustrine wetlands, but the role of these two aspects of sedimentation on macrophyte performance has rarely been examined. Here, we investigated the concurrent effects of sediment accretion and nutrient enrichment on the growth and propagation of Phalaris arundinacea L. using a factorial sediment burial by nutrient addit...

Littleseed canarygrass (Phalaris minor Retz.) is one of the most common and troublesome weeds infesting wheat crop in India. Repeated use during the last two decades of the ACCase-inhibiting herbicide (clodinafop) to control this weed has resulted in the occurrence of resistance. Fifty-three P. minor populations were collected from wheat fields in Haryana and Punjab states of India. The dose-re...

The Phalaris genus includes annual weed species such as short-spiked canarygrass (Phalaris brachystachys Link.), little-seed minor Retz.) and hood paradoxa L.), which are especially problematic in Spain; such, there is a need to develop models predict the timing of their emergence. Field experiments were conducted at two different locations during (2006/07 2007/08) three (from 2005/06 growing s...

This study examined physiochemical conditions and prokaryotic community structure (the bacterial and archaeal 16S rRNA genes and mcrA gene abundances and proportions), and evaluated the effect of reed canary grass cultivation and mineral fertilisation on these factors, in the 60 cm thick residual peat layer of experimental plots located on an abandoned peat extraction area. The archaeal proport...

B iological invasions occur when organisms are transported and become established in a new range in which they persist, proliferate, and spread (1). The negative consequences of invasions include loss of native biological diversity and community structure (and in extreme cases, the extinction of native species) (2); modification of ecosystem processes such as nutrient cycling and productivity p...
