Species with wide distribution, generally show variations in life history characteristics, which can be attributed to environmental causes. In this study, we analyzed the reproductive cycle and reproductive characteristics from three populations (Atlapexco, San Pablo Tetlapayac, and Santa Catarina) of the lizard Sceloporus variabilis from central Mexico. The specific goal of this study was to e...

Two new species of Anidiocerus from China, A. brevispinus Xue & Zhang sp. nov. and A. longimus Xue & Zhang sp. nov. are described and illustrated, and A. variabilis Maldonado-Capriles, 1976 is placed as a senior synonym of A. flavidus Cai & Shen, 1998, syn. nov. A redescription of the genus is provided together with a checklist and key for the separation of males. 

A new manoalide-related sesterterpene, 24-O-ethylmanoalide (3), was isolated from the Indian Ocean sponge Luffariella cf. variabilis, together with the known compounds manoalide (1), seco-manoalide, manoalide monoacetate and 24-O-methylmanoalide (2). The structure of compound 3 was elucidated by interpretation of its spectroscopic data.

Abstract The bee genera Callonychium Brethes, Psaenythia Gerstaecker and Anthrenoides Ducke are newly recorded in Piaui State, northeastern Brazil. species reported here brasilience (Ducke, 1907) variabilis Ducke, 1908, an as yet unidentified of Anthrenoides. Images all known distributional records these also provided. new occurrences herein expand the distribution range to Caatinga biome.

BACKGROUND Trigonopsis variabilis D-amino acid oxidase (TvDAO) is a well characterized enzyme used for cephalosporin C conversion on industrial scale. However, the demands on the enzyme with respect to activity, operational stability and costs also vary with the field of application. Processes that use the soluble enzyme suffer from fast inactivation of TvDAO while immobilized oxidase preparati...

We report fungal pathogens of invertebrates (FPI) (Entomophthorales, Hypocreales, and Orbiliales) from roots an endemic Mexican pine, Pinus greggii Engelm. ex Parl., at four primary montane forests using next-generation sequencing. found twenty-nine OTUs 18 genera FPI associated to the P. greggii. New records for Mexico are: Beauveria felina (DC.) J.W.Carmich., Dactylella mammillata S.M. Dixon,...

Relationships among species assigned to the ascosporic yeast genera Sporopachydermia, Stephanoascus, Trichomonascus, Wickerhamiella and Zygoascus, and to the associated anamorphic genera Arxula, Blastobotrys, Sympodiomyces and Trigonopsis, were determined from phylogenetic analyses of gene sequences from the nearly complete large-subunit rRNA gene, the mitochondrial small-subunit rRNA gene, and...
