An Evolutionary Study of Carex Subg. Psyllophorae (Cyperaceae) Sheds Light on a Strikingly Disjunct Distribution in the Southern Hemisphere, With Emphasis on Its Patagonian Diversification
(Frontiers Media, 2021-11)
Carex subgenus Psyllophorae is an engaging study group due to its early diversification compared to most Carex lineages, and its remarkable disjunct distribution in four continents corresponding to three independent sections: ...
Niche dynamics in amphitropical desert disjunct plants: Seeking for ecological and species‐specific influences
(Wiley, 2020-11)
Numerous studies have assessed whether species niches are conserved in geographically separated regions. However, most of them were performed on invasive species, with the limitation that such species have likely not yet ...
Climatic niche shift in the amphitropical disjunct grass Trichloris crinita
(2018-06)
Plant species disjunctions have attracted the interest of ecologists for decades. We investigated Trichloris crinita, a native C4 perennial grass with disjunct distribution between subtropical regions of North and South ...
Climatic niche shift in the amphitropical disjunct grass Trichloris crinita
(Public Library of Science, 2018-06)
Plant species disjunctions have attracted the interest of ecologists for decades. We investigated Trichloris crinita, a native C4 perennial grass with disjunct distribution between subtropical regions of North and South ...
Ecophylogeography of the disjunct South American xerophytic tree species Prosopis chilensis (Fabaceae)
(Wiley Blackwell Publishing, Inc, 2020-03)
The intraspecific evolutionary history of South American xerophytic plant species has been poorly explored. The tree species Prosopis chilensis has a disjunct distribution in four South American regions: Southern Peru, ...
Updating the distribution of Dicrodon guttulatum Duméril & Bibron, 1839 (Reptilia, Teiidae) with a disjunct population in the eastern slope of the Peruvian Andes
(PensoftBrasil, 2022-05-11)
We report a disjunct population of Dicrodon guttulatum Duméril & Bibron, 1839 on the eastern slope of the Cordillera Occidental in the inter-Andean Seasonally Dry Forests of the Marañón River, in the Departments of Cajamarca ...
Morphological and Molecular Evidence to Segregate a Disjunct Species of Hymenophyllum (Hymenophyllaceae) from Southern South America
(American Society of Plant Taxonomists, 2020-08-11)
Morphological studies and molecular phylogenetic analyses were carried out to assess the taxonomic status of Hymenophyllum caudiculatum, a species with a disjunct distribution in South America. The species is found in ...
Allotetraploids in Patagonia with Affinities to Western North American Diploids: Did Dispersal or Genome Doubling Occur First?
(Springer, 2012-09)
Amphitropical disjunct distributions between western North America and western South America have intrigued botanists for over a century. Here, specific examples of migration and speciation are investigated using herbaceous ...
The fossil flip-leaves (Retrophyllum, Podocarpaceae) of southern South America
(Botanical Society of America, 2017-09)
PREMISE OF THE STUDY: The flip-leaved podocarp Retrophyllum has a disjunct extant distribution in South American and Australasian tropical rainforests and a Gondwanic fossil record since the Eocene. Evolutionary, biogeographic, ...
