Selection and Complex Multigene Traits
(Wiley, 2013-05)
Phenotypic characters that display continuous variation are usually called ‘quantitative traits’ or ‘complex traits’. Alternatively, geneticists refer to them as ‘multigene traits’, because the underlying genetic architecture ...
Evidence of local adaptation and stabilizing selection on quantitative traits in populations of the multipurpose American species Acacia aroma (Fabaceae)
(Wiley Blackwell Publishing, Inc, 2019-10)
Economically and ecologically important quantitative traits of Acacia aroma are related to life history and the size and shape of fruits and leaves. Substantial variation is observed for these traits in natural populations, ...
Developing a breeding strategy for multiple trait selection in Prosopis alba Griseb., a native forest species of the Chaco Region in Argentina
(Oxford University Press, 2017-03)
Prosopis alba is a native forest tree growing in arid and semi-arid regions of Argentina. It is a multipurpose species suitable for silvopastoral systems. The breeding programmes of P. alba in Argentina started ~25 years ...
Measuring natural selection on multivariate phenotypic traits: a protocol for verifiable and reproducible analyses of natural selection
(Brill Academic Publishers, 2019-09)
The use of multiple regression analysis to quantify the regime and strength of natural selection in nature has been an influential approach in evolutionary biology over the last 36 years. However, many studies fail to ...
The search for Pleiades in trait constellations: functional integration and phenotypic selection in the complex flowers of Morrenia brachystephana (Apocynaceae)
(Wiley Blackwell Publishing, Inc, 2014-02)
Pollinator-mediated natural selection on single traits, such as corolla tube or spur length, has been well documented. However, flower phenotypes are usually complex, and selection is expected to act on several traits that ...
Pollinator-mediated selection in a specialized pollination system: matches and mismatches among populations
(Wiley Blackwell Publishing, Inc, 2010-09)
Most studies on pollinator-mediated selection have been performed in generalized rather than specialized pollination systems. This situation has impeded evaluation of the extent to which selection acts on attraction or ...
Phenotypic selection under two contrasting environments in wild sunflower and its crop‐wild hybrid
(Wiley Blackwell Publishing, Inc, 2019-06-05)
Hybridization is a common phenomenon in plants and can lead to the introgression of alleles from one population into another, generate new hybrid lineages, or cause species extinction. The environmental conditions and the ...
Community-level natural selection modes: A quadratic framework to link multiple functional traits with competitive ability
(Wiley Blackwell Publishing, Inc, 2018-11-05)
Research linking functional traits to competitive ability of coexisting species has largely relied on rectilinear correlations, yielding inconsistent results. Based on concepts borrowed from natural selection theory, we ...
Evidences of local adaptation in quantitative traits in Prosopis alba (Leguminosae)
(Springer, 2015-02)
Signals of selection on quantitative traits can be detected by the comparison between the genetic differentiation of molecular (neutral) markers and quantitative traits, by multivariate extensions of the same model and by ...
Phenotypic selection mosaic for flower length influenced by geographically varying hawkmoth pollinator proboscis length and abiotic environment
(Wiley Blackwell Publishing, Inc, 2019-09)
Biotic and abiotic context may affect the intensity of interspecific interactions and subsequently drive locally particular phenotypic selection patterns on interacting traits. We evaluated the geographical variation of ...
