Phylogenetics and reticulation among koelerioid clades, part I: Contraction of Trisetum, expansion of Acrospelion, Graphephorum, and Tzveleviochloa; Graciliotrisetum gen. nov. and resurrection of Aegialina (Poaceae, Pooideae, Poeae, Aveninae)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 3, Page 629-655, May 2025.
Phylogenetic analysis of Koeleriinae clades A and B yielded mostly congruent topologies in nuclear and plastid trees. However, several lineages resolved in strikingly incongruent positions in trees from different data sets, suggesting a reticulate origin for these taxa.

The Andes as a semi‐permeable geographical barrier: Genetic connectivity between structured populations in a widespread spider

open access: yesMolecular Ecology, Volume 33, Issue 11, June 2024.
Abstract Geographical barriers like mountain ranges impede genetic exchange among populations, promoting diversification. The effectiveness of these barriers in limiting gene flow varies between lineages due to each species' dispersal modes and capacities. Our understanding of how the Andes orogeny contributes to species diversification comes from well‐

Paleogene evolution of the External Betic Zone and geodynamic implications [PDF]

open access: yes, 2014
Interdisciplinary studies combining field data (geological and tectonic mapping, lithostratigraphic reconstructions, lithofacies characterization, correlations and sampling) and laboratory analyses (biostratigraphy, chronostratigraphy, clay mineralogy ...

Petrology, geochemistry and origin of the sierra de baza ophiolites (Betic cordillera, Spain) [PDF]

open access: yes, 2020
In this work we present for the first time a petrological-geochemical and genetic study of the Sierra de Baza ophiolites, which represent one of the ophiolitic occurrences of the Betic Cordillera (Southern Spain).

Neogene palaeogeography of the Betic Cordillera: an attempt at reconstruction

open access: yes, 1996
7 páginas.-- Peter F. Friend and Cristino J. Dabrio (eds.)The Neogene palaeogeography of the Betic Cordillera is reviewed in the context of the following western Mediterranean events: the initial opening of the Algerian basin and the Alboran Sea, the ...

Numerical modelling of mud volcanoes and their flows using constraints from the Gulf of Cadiz [PDF]

open access: yes, 2003
It is estimated that the total number of submarine mud volcanoes is between 1000 and 100 000. Because many are associated with greenhouse gases, such as methane, it is argued that the global flux of these gases to the atmosphere from the world’s ...

Shallow frontal deformation related to active continental subduction: structure and recent stresses in the westernmost Betic Cordillera

open access: yes, 2015
The westernmost Betic Cordillera front is located along the arcuate alpine belt formed by the interaction of the Eurasian-African plate boundary and the Alboran continental domain in between.

Karst caves and hydrology between geodesy and archeology: Field trip notes [PDF]

open access: yes, 2018
The Geodynamics-Earth-Tides-meeting-2016 was held in the Karst, the origin of geologic karstformation. Surface-rivers are absent, and water flows in channels over distances of 30 km, forming subsurface caves. Geodetic observations allow detecting caves

Middle-Late Triassic chondrichthyans remains from the Betic Range (Spain) [PDF]

open access: yes, 2017
Purpose: In the present study, we described, for first time, the chondrichthyan fauna from several Middle-Late Triassic sections in the Betic Domain and compare it with other recent described coeval faunas from the Iberian Ranges. Methods: Specimens were

JURASSIC PALEONTOLOGICAL HERITAGE OF MURCIA (BETIC CORDILLERA, SOUTH-EASTERN SPAIN) [PDF]

open access: yes, 2004
Jurassic rocks of the External and Internal Zones of the Betic Cordillera are widespread in the province of Murcia. Four areas are considered of special interest for stratigraphical and paleontological analysis: a) Sierra Quípar and b) Sierras Lúgar ...
