A genetic approach to the species problem in wild potato
(Wiley, 2012-07)
Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ...
Building matrix population models when individuals are non-identifiable
(Academic Press Ltd - Elsevier Science Ltd, 2019-01)
Matrix Population Models (MPM) are among the most widely used tools in ecology and evolution. These models consider the life cycle of an individual as composed by states to construct a matrix containing the likelihood of ...

(Elsevier Science, 2021-07)
Most of the earth´s surface has been transformed by man into urbanized and cultivated areas, decreasing and fragmenting the remaining natural habitats. These changes result in decreased plant population sizes and increased ...
Geographical parthenogenesis in the brown alga Scytosiphon lomentaria (Scytosiphonaceae): Sexuals in warm waters and parthenogens in cold waters
(Wiley Blackwell Publishing, Inc, 2021-08-20)
Geographical parthenogenesis, a phenomenon where parthenogens and their close sexual relatives inhabit distinct geographical areas, has been considered an interesting topic in evolutionary biology. Reports of geographical ...
Morphotypes of the lacustrine ostracod Limnocythere rionegroensis Cusminsky & Whatley from Patagonia, Argentina, shaped by aquatic environments
(Springer, 2017-03-01)
This study describes and quantifies morphological valve traits of the ostracod Limnocythere rionegroensis from Patagonian steppe lakes and explores their association with lake water characteristics. Surface ornamentation ...
Incorporating the process of vertical transmission into understanding of host-symbiont dynamics
(Wiley Blackwell Publishing, Inc, 2011-08)
Variation exists in the frequency of obligate, vertically transmitted symbiotic organisms within and among host populations; however, these patterns have not been adequately explained by variable fitness effects of symbionts ...
