The cytogenetic analysis of Frieseomelitta dispar and F. francoi revealed the chromosome numbers 2n = 30 and n = 15 and a karyotypic formula 2K = 4M+2M(t)+4A+20A(M). The number of chromosomes observed was consistent with those reported for other Frieseomelitta species. The occurrence of the M(t) chromosome and other features of the karyotype formulae suggest a close relationship between F. disp...

Muitas pesquisas demostraram que o conteúdo produzido no Twitter possui alto grau de correlação com o que ocorre no mundo real, o que levou ao desenvolvimento de aplicações em diversas áreas, abrangendo desde ...

We report here the successful assembly of the complete mitochondrial genomes of the northern spotted owl (Strix occidentalis caurina) and the barred owl (S. varia). We utilized sequence data from two sequencing methodologies, Illumina paired-end sequence data with insert lengths ranging from approximately 250 nucleotides (nt) to 9,600 nt and read lengths from 100-375 nt and Sanger-derived seque...

The present study intended to verify which factors (phylogenetic relationship or local ecological conditions) would determine how Frieseomelitta bees use floral resources. The data obtained in the literature on biocenotic studies of Apoidea visiting flowers in Brazil were analyzed, with identification and quantification of floral resources used by Frieseomelitta species in different areas. The ...
