Lower Central America is an important area to study recent population history and diversification of Neotropical species due to its complex and dynamic geology and climate. Phylogeographic studies in this region are few in comparison with other regions and even less for tree species. The aim of the present study was to characterize the phylogeograp...

Local adaptation is a critical evolutionary process that allows plants to grow better in their local compared to nonnative habitat and results in species‐wide geographic patterns of adaptive genetic variation. For forest tree species with a long generation time, this spatial genetic heterogeneity can shape the ability of trees to respond to rapid c...

The tree of life is highly reticulate, with the history of population divergence emerging from populations of gene phylogenies that reflect histories of introgression, lineage sorting and divergence. In this study, we investigate global patterns of oak diversity and test the hypothesis that there are regions of the oak genome that are broadly infor...

Las serpientes, víboras y/o culebras son vertebrados que pertenecen a la clase reptilia, animales con cuerpo cubierto de escamas y temperatura corporal variable (ectotérmicos). Pertenecen al superorden serpentes cuya característica principal es poseer cuerpos alargados, y carecer de extremidades, orificio auditivo y parpados móviles (son considerado...

Las lagartijas y tortugas son vertebrados que pertenecen a la clase reptilia, cuya característica principal es la presencia de escamas en su piel. Además, son animales de “sangre fría” (ectotérmicos). Los reptiles como las lagartijas y tortugas son filogenéticamente cercanos a otros organismos como las aves e incluso los mamíferos. En el mundo exi...

Los anfibios son un grupo de vertebrados que pertenecen a la clase Amphibia cuya principal característica es poseer la piel desnuda (sin escamas, plumas o pelo) y con muchas glándulas que los protegen al producir sustancias humectantes, antimicrobianas e incluso tóxicas. Son animales anamniotas (ausencia de saco amniótico), tetrápodos (cuatro extrem...

A survey was done to estimate margay abundance and activity in the context of high forest loss rates from avocado plantations for the temperate forest region of Michoacán state. Camera trap surveys were conducted from November 2015 to April 2020, recording 21 Margay detections of seven individuals. The capture rate ranged from 0.09 to 0.83 records/...

In this response, we address comments and clarify the rationale behind the choice of hypotheses aimed to describe the Quercus humboldtii phylogeography in the Colombian Andes. Finally, we explain our disagreement with the conclusions of a previous critique, since these are not necessarily adequate under the implemented population genetics approach.

Key message Oak species displayed high interspecific functional trait variation. The resource use strategy among oaks both at the above and belowground organs was guided by the fast-slow continuum. AbstractPlant functional ecology has focused on the study of functional strategies and general patterns of trait covariation. Mostly, studies intend to...

In this study, the effect of hybridization on the interspecific differentiation of two species of red oaks, Quercus acutifolia and Q. grahamii, was evaluated. It is thought that hybridization is possible between these two species since they can inhabit adjacently and have periods of synchronous flowering. In addition, individuals with intermediate...

The climatic and geological changes that occurred during the Quaternary, particularly the fluctuations during the glacial and interglacial periods of the Pleistocene, shaped the population demography and geographic distribution of many species. These processes have been studied in several groups of organisms in the Northern Hemisphere, but their in...

The Red List of Oaks 2020 provides and analyzes IUCN Red List assessments for the estimated 430 species in the genus Quercus—the most complete and comprehensive global analysis of extinction risk for oaks. The only previous global assessment of oaks was published in 2007 and included just 175 species (~40% of the genus; Oldfield and Eastwood, 2007)...

The 196 parties to the Convention on Biological Diversity (CBD) will soon agree to a post-2020 global framework for conserving the three elements of biodiversity (genetic, species, and ecosystem diversity) while ensuring sustainable development and benefit sharing. As the most significant global conservation policy mechanism, the new CBD framework...

Abstract The Mexican highlands are areas of high biological complexity where taxa of Nearctic and Neotropical origin and different population histories are found. To gain a more detailed view of the evolution of the biota in these regions, it is necessary to evaluate the effects of historical tectonic and climate events on species. Here, we analyze...

The tree of life is highly reticulate, with the history of population divergence buried amongst phylogenies deriving from introgression and lineage sorting. In this study, we test the hypothesis that there are regions of the oak ( Quercus , Fagaceae) genome that are broadly informative about phylogeny and investigate global patterns of oak diversit...

Se evalúa la perdida de hábitat para diferentes especies del género Quercus en el estado de Michoacán de Ocampo, en diferentes escenarios de cambio climático.

Resumen Se presenta una revisión de las investigaciones en el campo de la Ecología Molecular en México. Entre 1990 y 2016 se identificaron 656 artículos científicos relacionados. Los temas mejor representados son la genética de poblaciones (35.3% de los estudios) y la filogeografía (30.3%), mientras que los campos emergentes de la Ecología Molecula...

The northern Neotropical region is characterized by a heterogeneous geological and climatic history. Recent studies have shown contrasting patterns regarding the role of geographic elements as barriers that could have determined phylogeographic structure in various species. Recently, the phylogeography and biogeography of Quercus species have been...

Analyzing the structure of hybrid zones is important for inferring their origin, dynamics and evolutionary significance. We examined the geographic structure of phenotypic and genetic variation in the contact zone between two Mexican red oaks, Quercus affinis and Q. laurina. A total of 105 individuals from seven populations were sampled along a 600...

Premise of research. The most important diversity hot spot of genus Quercus (Fagaceae) in America is situated in southern Mexico. From this area down to the Colombian Andes, oak species diversity decreases considerably, but the pattern of species distribution and turnover has not been analyzed. This study aimed at determining geographical patterns...

We studied populations of Stenocereus pruinosus throughout Mexico, a species important for its edible fruit. The Tehuacán Valley is setting of ancient and the currently most active management of S. pruinosus; we hypothesized Tehuacán as the original area of domestication of S. pruinosus and expected to find there its highest genetic variation and o...

Mixed bird flocks are groups of individuals from different species that travel and forage together. Such groups are common in several bird communities around the world. We present species composition and activity patterns of mixed bird flocks in a region of the Central Andes of Colombia. We compared the number of species per flock, as well as the n...

• Poleward Pleistocene plant migration has been an important process structuring modern temperate and boreal plant communities, but the contribution of equatorward migration remains poorly understood. Paleobotanical evidence suggests Miocene or Pleistocene origin for temperate 'sky island' plant taxa in Mexico. These 'rear edge' populations situate...

In this study we assessed tree species richness, density, and composition patterns along a gradient of urbanization of a megacity. Our results show that total, native, and exotic tree densities were highest in green areas where larger spaces are considered for greening purposes. Conversely, total, native, and exotic tree species richness were highe...
