Stressful environments may enhance the occurrence of facilitative interspecific interactions between plants. In several regions, Zostera marina occurs in mixed assemblages. However, the potential effects of plant diversity on stress responses and stability properties of Z. marina are poorly understood. We investigated the resistance and recovery of Z. marina subjected to shading (1 mo) in a fie...

A field experiment with thin-layer capping was conducted in the Grenland fjords, Norway, for remediation in situ of mercury and dioxin-contaminated sediments. Experimental fields at 30 and 95 m depth were capped with (i) powdered activated carbon (AC) mixed with clay (AC+cla`y), (ii) clay, and (iii) crushed limestone. Ecological effects on the benthic community and species-feeding guilds were s...

In the carnivorous plant family Lentibulariaceae, all three genome compartments (nuclear, chloroplast, and mitochondria) have some of the highest rates of nucleotide substitutions across angiosperms. While the genera Genlisea and Utricularia have the smallest known flowering plant nuclear genomes, the chloroplast genomes (cpDNA) are mostly structurally conserved except for deletion and/or pseud...

The safety of many African traditional herbal remedies is doubtful due to lack of standardization. This study therefore attempted to standardize two polyherbal formulations from Ogbomoso, Oyo State, Nigeria, with respect to the relative proportions (weight-for-weight) of their botanical constituents. Information supplied by 41 local herbal practitioners was statistically screened for consistenc...

This study investigated the environmental characteristics and macrobenthic community structures of an intertidal flat located on Yubu Island in western coastal area Yellow Sea South Korea. The site has been well known for migratory bird protection designated by UNESCO. We collected samples surface depth core sediments macrobenthos from unused saltern surrounding it July 2017. Our results demons...

Peat and lacustrine sediments are a valuable source of knowledge about past biodiversity. Plant macrofossil remains were identified in mires northeastern Poland’s Knyszyn Forest. Among them, the species currently absent this area, such as Potamogeton pusillus, P. friesii, filiformis, Myriophyllum alterniflorum, Cladium mariscus, have been found. In addition, history Betula humilis its possible ...
