Rubus L. is a large and taxonomically complex genus, species of which exhibit apomixis, polyploidy, and frequent hybridization. Most of Chinese Rubus are assigned in two major sections, Idaeobatus and Malachobatus. To explore the phylogenetic relationships within Chinese Rubus, inferences upon three chloroplast DNA (rbcL, rpl20-rps12, and trnG-trnS), nuclear ribosomal ITS, and two low-copy nucl...

Whitebark pine (Pinus albicaulis) inhabits an expansive range in western North America, and it is a keystone species of subalpine environments. Whitebark is susceptible to multiple threats - climate change, white pine blister rust, mountain pine beetle, and fire exclusion - and it is suffering significant mortality range-wide, prompting the tree to be listed as 'globally endangered' by the Inte...

Geobotanical assessment of taxa with a high percentage of richness and endemism plays an important role on conservation plans. South-West Asia is one of the main biodiversity centers of the genus Onosma (Boraginaceae) comprising a high rate of species richness and endemism in Iran. Due to existing threatened factors to habitats and lack of sufficient data on conservation and distribution patter...

Cover crops can increase agricultural sustainability by protecting soil from erosion, increasing biodiversity, and symbiotically incorporating fixed nitrogen (N) into the soil. Nowadays, however, in Uruguay mostly grasses are planted autumn to protect erosion. Another option is study tropical legumes’ performance as cover crops, which fix substantial amounts of short growing periods, thereby br...

Climate change can alter ecological communities both directly, by driving shifts in species distributions and abundances, indirectly influencing the strength direction of interactions. Within benthic marine ecosystems, foundation such as canopy-forming macro-algae often underpin important cascades facilitative We examined wider impacts climate-driven relative abundances within a temperate reef ...

Temperate kelp forests contribute significantly to marine primary productivity and fuel many benthic pelagic food chains. A large proportion of biomass is exported from as detritus into recipient ecosystems, potentially contributing Blue Carbon sequestration. The degradation this organic material slow recent research has revealed the preservation photosynthetic functions over time. However, phy...

Seaweeds have been incorporated in the daily diet of several human cultures since ancient times, due to their nutritional characteristics and healthy properties. The brown seaweeds Undaria pinnatifida, Saccharina latissima, Sacchoriza polyschides, Laminaria ochroleuca were collected Viana do Castelo (Portugal) bay assess proximate composition analysis. As a result, algal biomass was dried, its ...
