Genetic diversity and patterns of population structure in Creole goats from the Americas
(Wiley, 2017)
Biodiversity studies are more efficient when large numbers of breeds belonging to several countries are involved, as they allow for an in-depth analysis of the within- and between-breed components of genetic diversity. A ...
Heritable variation in the survival of seedlings from Patagonian cypress marginal xeric populations coping with drought and extreme cold
(Springer, 2012-01)
The rear edges of tree species have begun to be perceived as highly valuable for genetic resources conservation and management. In view of expected climatic changes, the responses of trees at their xeric limits may largely ...
Genetic variability for responses to short‐ and long‐term salt stress in vegetative sunflower plants
(Wiley, 2012-12)
Sunflower (Helianthus annuus L.) has been rated as moderately salt‐resistant, and variability for salt resistance has been detected within this crop. However, variability in salt‐resistance mechanisms has not been assessed. ...
Genetic diversity near the DGAT1-2 gene for high oleic acid content and kernel trait variation in a maize breeding collection
(2018-08)
Previous studies in maize have identified three quantitative trait loci (QTLs) coding for high oleic acid content (HOAC) (QTLs oleic6-1, oleic6-2, and oleic6-3) at bins 6.04–6.05, proximal to the DGAT1-2 gene. The aims of ...
Impact of Pleistocene geoclimatic events on the genetic structure in mid-latitude South American plants: Insights from the phylogeography of Turnera sidoides complex (Passifloraceae, Turneroideae)
(Wiley Blackwell Publishing, Inc, 2018-12)
Aiming to shed light on the influence of Pleistocene geoclimatic events on the current genetic patterns in the flora of the South American Chaqueño Phytogeograpic Domain, we performed phylogeographic and Bayesian ancestral ...
Genotypic variation of physiological and morphological traits of seven olive cultivars under sustained and cyclic drought in Mendoza, Argentina
(2018-01-31)
The effects of two deficit irrigation regimes on the physiological, morphological, vegetative, and reproductive traits of seven olive cultivars were studied in a pot experiment. Specific leaf area (SLA) and SPAD chlorophyll ...
A tale of swinger insects: Signatures of past sexuality between divergent lineages of a parthenogenetic weevil revealed by ribosomal intraindividual variation
(Public Library of Science, 2018-05)
Naupactus cervinus (Boheman) (Curculionidae, Naupactini) is a parthenogenetic weevil native to the Paranaense Forest which displays high levels of genetic variation. Two divergent clades were identified, one ranging in ...
Genetic and morphometric differentiation between island and mainland southern elephant seal populations
(The Royal Society, 2001-02)
We compare genetic (both nuclear and mitochondrial) and morphometric measures between two putative populations of southern elephant seal (Mirounga leonina), and interpret the results in the context of data from mark-recapture ...
Variation in mitochondrial cytochrome c oxidase subunit I gene in Nezara viridula (Hemiptera: Pentatomidae) from Argentina
(Wiley Blackwell Publishing, Inc, 2019-05-19)
Here, we examine the genetic diversity in the agricultural pest Nezara viridula (Linnaeus,) from populations of Argentina using mitochondrial cytochrome c oxidase subunit I (COI) gene sequences. The DNA sequence comparisons ...
Genetic variation in neotropical butterflies is associated with sampling scale, species distributions, and historical forest dynamics
(Wiley Blackwell Publishing, Inc, 2021-06)
Previous studies of butterfly diversification in the Neotropics have focused on Amazonia and the tropical Andes, while southern regions of the continent have received little attention. To address the gap in knowledge about ...
