Identification of guitarfish species Rhinobatos percellens, R. horkelli, and Zapteryx brevirostris (Chondrichthyes) using mitochondrial genes and RFLP technique
(Springer, 2009-12-01)
The RFLP represents a fast and non-expensive tool to access species identification and can be used by fishery and law enforcement authorities to gather data from legal and illegal ray fisheries. In the present study, partial ...
Identification of the shark species Rhizoprionodon lalandii and R-porosus (Elasmobranchii, Carcharhinidae) by multiplex PCR and PCR-RFLP techniques
(Wiley-Blackwell Publishing, Inc, 2009-05-01)
Rhizoprionodon lalandii and R. porosus are widely distributed along the Atlantic coast of the Americas, living close to coastal areas and therefore frequently captured by seaboard fisheries. However, morphological ...
Statistical analysis of texture in trunk images for biometric identification of tree species
(Springer, 2015-04-01)
The identification of tree species is a key step for sustainable management plans of forest resources, as well as for several other applications that are based on such surveys. However, the present available techniques are ...
Identification of the endangered small red brocket deer (Mazama bororo) using noninvasive genetic techniques (Mammalia; Cervidae)
(Wiley-Blackwell Publishing, Inc, 2009-05-01)
The small red brocket deer Mazama bororo is one of the most endangered deer in the Neotropics. The great morphological similarities with three other sympatric brocket deer species, coupled with the fact that they inhabit ...
Molecular identification of the fish fauna from the pantanal flood plain area in Brazil
(Taylor & Francis Ltd, 2017-09-01)
The Pantanal is under the influence of the Paraguay River flood regime is considered to be one of the largest wetlands of the world, and has rich biodiversity, including fishes. Until now, the identification of fish species ...
Differentiation of deer species of the genus Mazama by track morphometry
(Taylor & Francis Ltd, 2014-09-02)
We analyzed morphometric variables of tracks of the five species in the genus Mazama known from Brazil to determine if footprint morphometry can distinguish these species. Tracks from adult M. americana, M. bororo, M. ...
Adiantum (Pteridaceae) in Brazil: Key to the species and illustrations
(Revista Biota Neotropica, 2020-01-01)
Adiantum is a Pantropical genus of ferns, monophyletic, and has about 225 species. It can be recognized by the indusia with veins, bearing sporangia directly on the underside of its reflexed tissue. About 110 species occur ...
Development of molecular markers for the Eucalyptus species identification
(Univ Cordoba, Fac Ciencias Agricolas, 2017-07-01)
One of the main problems faced in several eucalypt breeding programs is the difficulty to identify the species and hybrids. This study aimed to find molecular markers associated with five species of Eucalyptus (E. saligna, ...
Gender identification of five genera of stingless bees (Apidae, Meliponini) based on wing morphology
(FUNPEC-EDITORA, 2009)
Currently, the identification of pollinators is a critical necessity of conservation programs. After it was found that features extracted from patterns of wing venation are sufficient to discriminate among insect species, ...
DNA Barcode reveals mislabelling in the identification of marine fish swimming bladders for commercialization
(2019-06-01)
Sequences of the mitochondrial gene COI (DNA Barcode) wereused to identify marine fish swimming bladders commercialized in Brazil. The comparisons of the obtained sequences of the samples registered as catfish for the ...
