Geographic variation in cranial morphology in Thrichomys apereoides (Rodentia : Echimyidae). II. Geographic units, morphological discontinuities, and sampling gaps
(Alliance Communications Group Division Allen PressLawrenceEUA, 2002)
Spatiotemporal analysis of the genetic and morphological variation of Iphigenia brasiliensis (Mollusca: Bivalvia) from the southwest tropical Atlantic
(Pontificia Universidad Católica de Valparaíso, 2023)
Phenotypical variation and taxonomic correlates of five closely related Andean species of Poa (Poaceae) along geographic and climatic gradients
(Magnolia Press, 2014-10)
Poa anfamensis, P. jujuyensis, P.lilloi, P. parviceps and P. scaberula (Poaceae) are a group of morphologically similar species. These species inhabit cool grasslands and mesic puna. They are highly polymorphic and their ...
Variation in mandible shape in Thrichomys apereoides (Mammalia: Rodentia): Geometric analysis of a complex morphological structure
(2000-09-01)
The model of development and evolution of complex morphological structures conceived by Atchley and Hall in 1991 (Biol. Rev. 66:101-157), which establishes that changes at the macroscopic, morphogenetic level can be ...

Morphological variations of hippocampal formation in epilepsy: Image, clinical and electrophysiological data
(Elsevier B.V., 2013-01-01)
Morphological variations of hippocampal formation (MVHF) are observed in patients with epilepsy but also in asymptomatic individuals. the precise role of these findings in epilepsy is not yet fully understood. This study ...
The taxonomy and morphological and anatomical differentiation of populations of Leiothrix crassifolia (Eriocaulaceae)
(Springer, 1996-01-01)
The morphological and anatomical leaf and scape differentiation of Leiothrix crassifolia is analysed and classified into seven types (I, II, III, IV, V, VI, Vn). The species has a relatively wide distribution in the campo ...
Phenotypic variation of leptodactylus cupreus caramaschi, são-pedro and feio, 2008 (Anura, Leptodactylidae)
(2013-02-18)
This study describes for the first time the female of Leptodactylus cupreus and provides new information concerning its geographical distribution, male's morphology and bioacustics. Leptodactylus cupreus, a poorly known ...
Cis-regulatory variation in the shavenbaby gene underlies intraspecific phenotypic variation, mirroring interspecific divergence in the same trait
(Wiley Blackwell Publishing, Inc, 2020-12)
Despite considerable progress in recent decades in dissecting the genetic causes of natural morphological variation, there is limited understanding of how variation within species ultimately contributes to species differences. ...
