Features of myoneural junctions in the extraocular muscles of the opossum (Didelphis albiventris)
(1996-12-01)
The myoneural junctions present in the opossum (Didelphis albiventris) extraocular muscles were studied through histochemical and ultrastructural techniques. Three different types of junction were shown: two single types, ...
Direct molecular approach to monitoring bacterial colonization on vacuum-packaged beef
(American Society for Microbiology, 2006-08)
Denaturing gradient gel electrophoresis allowed us to monitor total bacterial communities and to establish a pattern of succession between species in vacuum-packaged beef stored at 2 and 8°C for 9 weeks and 14 days. ...
Habitat specificity can blur the predictions of species-energy theory: A case study of tenebrionid beetles adapted to aridity
(Academic Press Ltd - Elsevier Science Ltd, 2011-08)
Species-energy theory predicts a positive relationship between species richness and energy. The mechanism assumed by this theory is that high energy promotes high population abundance, which in turn promotes high species ...
A New Miniature Characid (Ostariophysi: Characiformes: Characidae), with Phylogenetic Position Inferred from Morphological and Molecular Data
(2013-01-02)
Erythrocharax altipinnis is described from the Serra do Cachimbo, Pará, Brazil. The new taxon is distinguished from all of the Characidae genera by having the pelvic bones firmly attached through the isquiatic processes; ...
