Abstract Background : It is a practice to use traditional medicine for curing various illnesses in West Africa. Acacia hebecladoides , albida and Gmelina arborea were selected based on their belief treating ailments such as: hallucinations, inflammation tuberculosis. The study sought validate the antitubercular activity, antioxidant properties phytochemical components of extracts fractions leav...

La investigación se realizó con ecotipos de chile piquín Coahuila, Nuevo León y Zacatecas. Se evaluaron plantas del segundo año producción. utilizaron dos ambientes: a) macro túneles malla blanca, roja azul, negra tipo raschel 30% sombreo; b) campo abierto 100% transmisión luz. inocularon 50 esporas un conglomerado hongos micorrízicos arbusculares (Glomus mosseae, Rhizophagus intraradices, Scle...

Eighty-six important findings of 54 species vascular plants, bryophytes, lichens and fungi acquired lately from the Murmansk Region are reported. The were defined as if they red-listed in Russia and/or Region, new for protected areas, represented other particularly rare known not more than five locations well northernmost localities Europe or globally. Three fungal (Phaeolus schweinitzii, Phell...

Sudano-Sahelian domain is the poorest in biodiversity because of climate which unfavourable compared to equatorial climate. The unsustainable agricultural practices associated with this climatic roughness are among main factors habitat destruction, hence destruction phytogeographic environment. In order valorize and conserve sudano-sahelian plant resources, a study was carried out seasonal agro...

Ichthyoplankton surveys were conducted in surface waters of the northern Gulf of Mexico (NGoM) over a three-year period (2006-2008) to determine the relative value of this region as early life habitat of sailfish (Istiophorus platypterus), blue marlin (Makaira nigricans), white marlin (Kajikia albida), and swordfish (Xiphias gladius). Sailfish were the dominant billfish collected in summer surv...

Foliar trichomes of gray-leaved Tillandsioideae (Bromeliaceae) are highly reflective, suggesting a role in protecting the leaf against direct sunlight in exposed niches. The performance of photosystem II, as denoted by the chlorophyll fluorescence characteristic Fv /Fm , was determined for seven Tillandsia species and Vriesea barclayana that were exposed to excessive light, with trichomes eithe...

Accurate species delimitation is fundamental to biology. Traditionally, species were delimited based on morphological characters, sometimes leading to taxonomic uncertainty in morphologically conserved taxa. Recently, multiple taxonomically challenging cases have benefited from integrative taxonomy-an approach that highlights congruence among different disciplines and invokes evolutionary expla...
