This study presents a detailed taxonomic review of water mite deutonymphs of the genus Unionicola Haldeman, 1842 (Hygrobatoidea: Unionicolidae) found in the fauna of Russia during the long-term survey period of 1979-2013. The review includes descriptions and illustrations of 14 Unionicola species found in this country: U. aculeata (Koenike, 1890), U. arcuata (Wolcott, 1898), U. bonzi (Claparède...

Watersipora is an invasive genus of bryozoans, easily dispersed by fouled vessels. We examined Cytochrome c oxidase subunit I haplotypes from introduced populations on the US Pacific coastline to investigate geographic segregation of species and/or haplotypes. In California, the W. subtorquata group fell into three major sub-groups: W. subtorquata clades A and B, and W. "new sp.". W. subtorquat...

A 12-yr study of fungi associated with Cannabis has revealed that many taxa cited in the Cannabis literature are based on misdeterminations or synonyms of species with wide host ranges (McPartland, 1992, 1994b, 1995b). New species have been discovered – Phomopsis ganjae (McPartland, 1983), Schiffnerula cannabis (McPartland&Hughes, 1994a), Fusicoccum marconii, Leptodothiorella marconii (McPartla...

In the present study, the effect of seaweed liquid fertilizer (SLF) of Ulva fasciata, Nizimuddinia zunardini and Gracilaria corticata without chemical fertilizer on seed germination, growth parameter, pigment and carbohydrate content of Wheat var. (Chamran) was investigated. The seeds soaked with aqueous extract of seaweeds performed better when compared to the water soaked controls. The 10% co...

Increases in sediment and drift algae accumulations have caused degradation of coastal lagoons worldwide. It is well known that these factors are stressors of seagrass beds, sediment fauna and coral reefs. However, little is known about the impacts on temperate hard-bottom assemblages within soft-bottom lagoons. To test if accumulations of sediment and drift algae (stress) affected recruitment ...

the antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including hypnea hamulosa, gracilaria corticata and enteromorpha intestinalis wereinvestigated.antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, dpph radical scavenging activity and ferric reducing antioxidant power. antibacterial activity w...
