Geometric morphometrics of the skull of Tinamidae (Aves, Palaeognathae)
(Elsevier Gmbh, 2010-12)
The Tinamidae comprise exclusively Neotropical palaegnathous birds, with homogeneous body morphology and no sexual dimorphism. The goal of this work was to explore the variation in skull morphology between taxa and its ...
New insights to discriminate between Sympterygia acuta Garman 1877 and Sympterygia bonapartii Müller & Henle, 1841 (Rajidae) of the Southwest Atlantic Ocean: On the use of geometric morphometrics and spinulation patterns
(Wiley Blackwell Publishing, Inc, 2015-04)
Geometric-morphometric and spinulation pattern approaches were employed to assess the discrimination of two species of Sympterygia skates in the Southwest Atlantic: Sympterygia acuta Garman 1877 and Sympterygia bonapartii ...
Genetic and Morphometric Variability in Caiman latirostris (Broad-Snouted Caiman), Reptilia, Alligatoridae
(Wiley-liss, Div John Wiley & Sons Inc, 2009-04)
Caiman latirostris (broad-snouted caiman) is a crocodilian species from Argentina subject of management plans. The goal of this study was estimating the distribution of genetic variability using RAPD markers and quantitative ...
Life history or stylistic variation? A geometric morphometric method for evaluation of Fishtail point variability
(Elsevier, 2019-10)
Fishtail points are considered an indicator of the presence for one of the earliest and most successful human adaptations during the late Pleistocene in South America (~12,900–12,200 cal BP). Although these points display ...

Morphometric and Cytogenetic Studies in Mimosa diversipila (Mimosoideae, Leguminosae) and Their Taxonomic and Evolutionary Inferences
(American Society of Plant Taxonomists, 2014-01)
Here we describe the morphological variability, chromosome number, and chromosome size in Mimosa diversipila. This speciescomprises two varieties, which are distinguished by the indumentum. However, this character is ...
