Documentamos el primer registro fotográfico más al sur y para aguas interiores de México la negreta ala blanca (Melanitta fusca). El 12 diciembre 2013 observamos una hembra adulta esta especie en laguna Refugio Salcido del municipio Durango, ubicada a 15 km ciudad Durango; aproximadamente 1,450 m sureste límite distribución invernal.

Twelve species of lizards and the marine toad (Bufo marinus L.) were surveyed in six habitat types at three sites on the island of Saipan, Mariana Islands, using visual censuses, hand captures, and adhesive traps. Toads were rare on each of the study sites. Anolis carolinensis Cuvier was most common in disturbed forests. Four species of geckos, Gehyra mutilata (Wiegmann), G. oceanica (Lesson), ...

A study was conducted to assess the performance of maize hybrids with Bt event MON810 (Bt-hybrids) against the maize stem borer Busseola fusca (Fuller) in a biosafety greenhouse (BGH) and against the spotted stem borer Chilo partellus (Swinhoe) under confined field trials (CFT) in Kenya for three seasons during 2013-2014. The study comprised 14 non-commercialized hybrids (seven pairs of near-is...

The genus Sonotetranychus consisted of seven species prior to this study. Sonotetranychus menziesii sp. nov., collected on Nothofagus menziesii and N. fusca from New Zealand, is described based on females, protonymphs, deutonymphs and a male. An updated key to the species of Sonotetranychus is provided.

Six species in the genus Busonia Distant are described and illustrated, including five new species from Thailand and Malaysia: Busonia curvata, B. fusca, B. lactata, B. micrata, B. serrata, spp. nov., and one newly recorded species from China: Busonia albilateralis Maldonado-Capriles. A redescription of this genus is provided together with a key to species for separation of males.

Excessive use of detergents in wide industrial processes results unwanted surfactant pollution. Among them, sodium dodecyl sulphate (SDS) has well-known history to be used pharmaceutical and applications. However, if discharged without treatment, it can cause toxic effects on living organisms especially the aquatic life. Floating treatment wetlands (FTWs) could a cost-effective eco-friendly opt...

The cellulases of Streptomyces thermodiastaticus (strain 2Sts) and thermomonospora fusca (strain 190Th) were produced with carboxymethyl-cellulose (CMC) serving as the carbon source during growth. Both cellulases act by random internal hydrolysis of the CMC chain, producing cellobiose, glucose, and intermediate length oligosaccharides. Cellobiase was not detected in culture filtrates produced u...

Competition or facilitation characterises intra- and interspecific interactions within communities of species that utilize the same resources. Temperature is an important factor influencing those interactions and eventual outcomes. The noctuid stemborers, Busseola fusca and Sesamia calamistis and the crambid Chilo partellus attack maize in sub-Saharan Africa. They often occur as a community of ...
