Genetic diversity in caribou linked to past and future climate change

G Yannic, L Pellissier, J Ortego, N Lecomte… - Nature Climate …, 2014 - nature.com
Climate-driven range fluctuations during the Pleistocene have continuously reshaped species
distribution leading to populations of contrasting genetic diversity. Contemporary climate …

Evolutionary and demographic history of the Californian scrub white oak species complex: an integrative approach

J Ortego, V Noguerales, PF Gugger… - Molecular …, 2015 - Wiley Online Library
Understanding the factors promoting species formation is a major task in evolutionary
research. Here, we employ an integrative approach to study the evolutionary history of the …

Climatically stable landscapes predict patterns of genetic structure and admixture in the Californian canyon live oak

J Ortego, PF Gugger, VL Sork - Journal of Biogeography, 2015 - Wiley Online Library
Aim We studied which factors shape contemporary patterns of genetic structure, diversity
and admixture in the canyon live oak (Quercus chrysolepis). Specifically, we tested two …

Influence of environmental heterogeneity on genetic diversity and structure in an endemic southern Californian oak

J Ortego, EC Riordan, PF Gugger, VL Sork - Molecular Ecology, 2012 - Wiley Online Library
Understanding how specific environmental factors shape gene flow while disentangling
their importance relative to the effects of geographical isolation is a major question in …

Association of genetic and phenotypic variability with geography and climate in three southern California oaks

EC Riordan, PF Gugger, J Ortego… - American journal of …, 2016 - Wiley Online Library
PREMISE OF THE STUDY: Geography and climate shape the distribution of organisms,
their genotypes, and their phenotypes. To understand historical and future evolutionary and …

[HTML][HTML] Hierarchical genetic structure shaped by topography in a narrow-endemic montane grasshopper

V Noguerales, PJ Cordero, J Ortego - BMC Evolutionary Biology, 2016 - Springer
Background Understanding the underlying processes shaping spatial patterns of genetic
structure in free-ranging organisms is a central topic in evolutionary biology. Here, we aim to …

Geographical isolation versus dispersal: Relictual alpine grasshoppers support a model of interglacial diversification with limited hybridization

J Ortego, LL Knowles - Molecular Ecology, 2022 - Wiley Online Library
Alpine biotas are paradigmatic of the countervailing roles of geographical isolation and
dispersal during diversification. In temperate regions, repeated distributional shifts driven by …

Temporal variation of heterozygosity‐based assortative mating and related benefits in a lesser kestrel population

J Ortego, G Calabuig, R Bonal, A Munoz… - Journal of …, 2009 - academic.oup.com
Heterozygosity as a target of mate choice has received much attention in recent years and
there is growing evidence supporting its role in the evolution of mate preferences. In this study …

Genetic Consequences of Habitat Fragmentation in Long-Lived Tree Species: The Case of the Mediterranean Holm Oak (Quercus ilex, L.)

J Ortego, R Bonal, A Muñoz - Journal of Heredity, 2010 - academic.oup.com
Large-scale forest fragmentation can increase interpopulation genetic differentiation and erode
the genetic variability of remnant plant populations. In this study, we analyze the extent of …

Influence of climatic niche suitability and geographical overlap on hybridization patterns among southern Californian oaks

J Ortego, PF Gugger, EC Riordan… - Journal of …, 2014 - Wiley Online Library
Aim Information on the association between geographical patterns of hybridization and the
climatic niche requirements and co‐occurrence of the species involved can provide important …
