A global synonymical checklist of the species and higher taxa insect order Megaloptera is provided. The includes both extant extinct taxa, recognizes 2 families, 4 subfamilies, 48 genera, 425 species, 6 subspecies. Both families (Corydalidae Sialidae), three four subfamilies (Corydalinae, Chauliodinae, Sialinae) are known from species; Sharasialinae (Sialidae) entirely extinct. Country-level ge...

selection (BPPS), which is based on a two-way mixture model and can simultaneously classify protein sequences into distinct subfamilies and select conserved positions that are characteristic of these subfamilies. When applied to P-loop GTPases, this revealed within Rab, Rho, Ras, and Ran a canonical network of molecular interactions centered on bound nucleotide. This network presumably performs...

Family Pentatomidae is represented by four subfamilies (Asopinae, Pentatominae, Phyllocephalinae and Podopinae) and 86 genera in south India. Pentatominae are the dominant group represented by 29 tribes and 72 genera. An illustrated key including the habitus of majority of genera as well as illustrations of important diagnostic features are given for the subfamilies, tribes and genera occurring...

Abstract Plant-bee networks are rarely, if ever, studied quantitatively at continental scales, yet these have the potential to inform how biota and ecosystems assembled beyond narrower regional biomes. The short-tongued bee family Colletidae comprises major component of diversity in Australia, with three key subfamilies: Neopasiphaeinae, Hylaeinae, Euryglossinae. We use museum data (> 27,000...

Endosperms from seeds of different subfamilies of Leguminosae were submitted to sequential aqueous and alkaline aqueous extractions. The extractions from species belonging to the Mimosoideae and Faboideae subfamilies yielded galactomannans with constant Man:Gal ratios, whereas the extractions from Caesalpinioideae seeds gave rise to galactomannans with increasing values of the Man:Gal ratio. Th...

Alus are the most abundant and successful short interspersed nuclear elements found in primate genomes. In humans, they represent about 10% of the genome, although few are retrotransposition-competent and are clustered into subfamilies according to the source gene from which they evolved. Recombination between them can lead to genomic rearrangements of clinical and evolutionary significance. In...

During germ cell and preimplantation development, mammalian cells undergo nearly complete reprogramming of DNA methylation patterns. We profiled the methylomes of human and chimp sperm as a basis for comparison to methylation patterns of ESCs. Although the majority of promoters escape methylation in both ESCs and sperm, the corresponding hypomethylated regions show substantial structural differ...
