Mitochondrial DNA sequence variation can be used to infer honey bee evolutionary relationships. We examined DNA sequence diversity in the cytochrome C oxidase I (COI or Cox1) gene segment of the mitochondrial genome in 112 samples of Apis mellifera from 15 different populations in Turkey. Six novel haplotypes were found for the COI gene segment. There were eight variable sites in the COI g...

The neogregarine Apicystis bombi is considered a low prevalence parasite of Bombus spp. Before our work it has only once been detected in one single specimen of the Western honeybee Apis mellifera. This contribution reports the presence of A. bombi parasitizing both A. mellifera and Bombus terrestris at a site in Northwestern Argentine Patagonia (Bariloche, close to the border with Chile) and a...

The effect of lignin structural units on enzymatic hydrolysis lignocellulosic biomass was investigated, especially the inhibitory role in non-productive adsorption with enzymes. Milled wood (MWL) isolated from different hardwoods poplar, eucalyptus and acacia. samples were characterized by elemental analysis, gel permeation chromatography, nitrobenzene oxidation fourier infrared spectroscopy. m...

Ju/'hoan hunters from Nyae Nyae, near Tsumkwe in Namibia, demonstrate the manufacture of three fixative pastes made from plant extracts, and poison made from grubs and plant extracts. Ammocharis coranica and Terminalia sericea produce simple glue. Ozoroa schinzii latex mixed with carbonized Aristeda adscensionis grass is a compound adhesive. Composite poison is made from Chrysomelid grub viscer...

Abstract The need to address wildlife conservation outside of protected areas has become more urgent than ever before meet environmental and socio‐economic goals. However, there is limited knowledge about how woody plants respond herbivory within landscapes shared by domestic herbivores in African savanna, thus management decisions might be based on inaccurate information ultimately ineffective...

The response of microbial functional diversity as well as its resistance to stress or disturbances caused by the introduction of an exotic tree species, Acacia holosericea, ectomycorrhized or not with Pisolithus albus, was examined. The results show that this ectomycorrhizal fungus promotes drastically the growth of this fast-growing tree species in field conditions after 7 years of plantation....

It is proved that a Hausdorff continuum is unicoherent if it is the union of two unicoherent continua whose intersection is connected and locally connected.

An environmentally benign and clean synthesis of aryl-hydrazones by reacting variety of carbonyl compounds with thiosemicarbazide, semicarbazide, aminoguanidine, and phenyl hydrazine has been achieved using aqueous extract of Acacia concinna pods as a natural surfactant type catalyst. We found that the aqueous extract of Acacia concinna pods could be effectively used for the synthesis of aryl-h...
