How natural selection shapes genetic differentiation in the MHC region: A case study with Native Americans
(Elsevier, 2021)
The Human Leukocyte Antigen (HLA) loci are extremely well documented targets of balancing selection, yet few studies have explored how selection affects population differentiation at these loci. In the present study we ...
Evidence of body size and shape stasis driven by selection in Patagonian lizards of the Phymaturus patagonicus clade (Squamata: Liolaemini)
(Academic Press Inc Elsevier Science, 2018-12)
During the speciation process sibling lineages accumulate differences in time (e.g. genetic, morphological, and/or ecological). Phenotypic traits such as size or shape, however, could experience rapid changes or show stasis ...
Body size and allometric shape variation in the molly Poecilia vivipara along a gradient of salinity and predation
(Biomed Central Ltd, 2014-12-04)
Background: Phenotypic diversity among populations may result from divergent natural selection acting directly on traits or via correlated responses to changes in other traits. One of the most frequent patterns of correlated ...
Liquid phase dehydration of 1-indanol: Selective synthesis of indene over microporous acid catalysts
(Elsevier, 2015-09)
The selective dehydration of 1-indanol in liquid-phase was studied at 363 K and 2 bar, over solid acid catalysts, and using cyclohexane as a solvent. Mesoporous SiO2-Al2O3 with a high density of strong Lewis acid sites ...
Phenotypic diversity in female body shape is related to reproductive potential in Tupinambis merianae lizards
(Finnish Zoological Botanical Publishing Board, 2015-06)
A major goal in evolutionary biology is to determine the mechanisms responsible for maintaining phenotypic variation. Species that have evolved intersexual differences provide an opportunity to increase our understanding ...
Skull shape and size divergence in dolphins of the genus Sotalia: A tridimensional morphometric analysis
(Alliance Communications Group Division Allen PressLawrenceEUA, 2002)
Additive Manufacturing of Co-Ni-Ga High-Temperature Shape Memory Alloy: Processability and Phase Transformation Behavior
(Springer, 2020-03)
Co-Ni-Ga high-temperature shape memory alloy is additively processed by selective laser melting for the first time. Reversible martensitic transformation of the as-built material is proven by differential scanning calorimetry. ...
Head shape evolution in Tropidurinae lizards: does locomotion constrain diet?
(WILEY-BLACKWELL PUBLISHING, INC, 2008)
Different components of complex integrated systems may be specialized for different functions, and thus the selective pressures acting on the system as a whole may be conflicting and can ultimately constrain organismal ...
Bimodal trait distributions with large variances question the reliability of trait-based aggregate models
(Springer, 2016-12-01)
Functionally diverse communities can adjust their species composition to altered environmental conditions, which may influence food web dynamics. Trait-based aggregate models cope with this complexity by ignoring details ...
