The 196 parties to the Convention on Biological Diversity (CBD) will soon agree a post-2020 global framework for conserving three elements of biodiversity (genetic, species, and ecosystem diversity) while ensuring sustainable development benefit sharing. As most significant conservation policy mechanism, new CBD has far-reaching consequences- it guide actions reporting each member country until 2050. In previous strategies, as well other major mechanisms, targets indicators genetic diversity...
Summary The tree of life is highly reticulate, with the history population divergence emerging from populations gene phylogenies that reflect histories introgression, lineage sorting and divergence. In this study, we investigate global patterns oak diversity test hypothesis there are regions genome broadly informative about phylogeny. We utilize fossil data restriction‐site associated DNA sequencing ( RAD ‐seq) for 632 individuals representing nearly 250 Quercus species to infer a...

Abstract Local adaptation is a critical evolutionary process that allows plants to grow better in their local compared non‐native habitat and results species‐wide geographic patterns of adaptive genetic variation. For forest tree species with long generation time, this spatial heterogeneity can shape the ability trees respond rapid climate change. Here, we identify genomic variation may confer environmental adaptations then predict extent mismatch under future as tool for restoration or...
Global change drives biodiversity shifts worldwide, but these are poorly understood in highly diverse tropical regions. In mountains, plants mostly expected to migrate upslope response warming. To assess this, we analyze elevation ranges of species Mesoamerican cloud forests using three decades species' occurrence records. Our findings reveal a mean shift 1.8 2.7 meters per year since 1979 driven by the retreat less thermophilic montane species. These accompanied retreating lower and upper...
Premise of research. The most important diversity hot spot genus Quercus (Fagaceae) in America is situated southern Mexico. From this area down to the Colombian Andes, oak species decreases considerably, but pattern distribution and turnover has not been analyzed. This study aimed at determining geographical patterns turnover, distribution, endemism for Neotropical species.Methodology. Occurrence records 58 belonging Lobatae sections were obtained. Patterns determined by comparing...
Due to a complex geological and biotic history, the Isthmus of Tehuantepec (IT), has been long recognized as driver for evolutionary divergence numerous lowland highland taxa. Widely distributed in lowlands American continent, White-Tipped Dove (Leptotila verreauxi) is polytypic species with 13 subspecies. Four these have recorded Mexico, distribution three abuts at IT, suggesting contact zone. To estimate phylogenetic patterns, times genetic differentiation, we examined two mtDNA (ND2 COI)...
In this study we assessed tree species richness, density, and composition patterns along a gradient of urbanization megacity. Our results show that total, native, exotic densities were highest in green areas where larger spaces are considered for greening purposes. Conversely, richness land uses with intermediate levels urban development (residential, residential-commercial areas). Not finding less developed suggests cultural factors may shape the array planted within cities. Supporting...
Abstract Analyzing the structure of hybrid zones is important for inferring their origin, dynamics and evolutionary significance. We examined geographic phenotypic genetic variation in contact zone between two Mexican red oaks, Q uercus affinis . laurina A total 105 individuals from seven populations were sampled along a 600‐km latitudinal gradient representing distribution area species zone. Individuals genotyped nine nuclear four chloroplast DNA microsatellite loci (nc SSR cp ,...
Mixed bird flocks are groups of individuals from different species that travel and forage together. Suchgroups common in several communities around the world. We present composition activity patternsof mixed a region Central Andes Colombia. compared number per flock, aswell as among 3 habitats. tested hypotheses concerning daily andthe co-occurrences within them. recorded 75 species, flock varied 4 to21. Our data suggest habitat affects but not their number, flocksis similar throughout day....
The Mexican highlands are areas of high biological complexity where taxa Nearctic and Neotropical origin different population histories found. To gain a more detailed view the evolution biota in these regions, it is necessary to evaluate effects historical tectonic climate events on species. Here, we analyzed phylogeographic structure, demographic processes, contemporary period, Last Glacial Maximum (LGM) Interglacial (LIG) ecological niche models
The climatic and geological changes that occurred during the Quaternary, particularly fluctuations glacial interglacial periods of Pleistocene, shaped population demography geographic distribution many species. These processes have been studied in several groups organisms Northern Hemisphere, but their influence on evolution Neotropical montane species ecosystems remains unclear. This study contributes to understanding effect late Pleistocene Andean mountain forests. First, we describe...
Lower Central America is an important area to study recent population history and diversification of Neotropical species due its complex dynamic geology climate. Phylogeographic studies in this region are few comparison with other regions even less for tree species. The aim the present was characterize phylogeographic structure 2 partially co-distributed endemic oak (Quercus costaricensis Q. bumelioides) Costa Rican mountains using chloroplast short sequence repeats (cpSSRs), test effect...
Summary The tree of life is highly reticulate, with the history population divergence buried amongst phylogenies deriving from introgression and lineage sorting. In this study, we test hypothesis that there are regions oak ( Quercus , Fagaceae) genome broadly informative about phylogeny investigate global patterns diversity. We utilize fossil data restriction-site associated DNA sequencing (RAD-seq) for 632 individuals representing ca. 250 species to infer a time-calibrated world’s oaks. use...
Within the genus Quercus there are species with a shrubby habit that have been little studied worldwide. In Mexico, several shrub within section taxonomically highly problematic. These include eight named taxa share traits such as abaxially tomentose leaves and growth of stems from one or multiple rhizomes, is evidence additional undescribed species. Here, purhepecha described illustrated new white oak species, very restricted distribution Cuitzeo basin in Trans-Mexican Volcanic Belt (TMVB),...
Se presenta una revisión de las investigaciones en el campo la Ecología Molecular México. Entre 1990 y 2016 se identificaron 656 artículos científicos relacionados. Los temas mejor representados son genética poblaciones (35.3% los estudios) filogeografía (30.3%), mientras que campos emergentes Molecular, como genómica del paisaje, ecología trófica basada secuencias ADN análisis parentesco conducta, estuvieron poco representados. sistemas más estudiados han sido animales (58.5%) plantas...
Abstract A survey was done to estimate margay abundance and activity in the context of high forest loss rates from avocado plantations for temperate region Michoacán state. Camera trap surveys were conducted November 2015 April 2020, recording 21 Margay detections seven individuals. The capture rate ranged 0.09 0.83 records/100 nights. mean temporal density 0.12 ind./km 2 , with an peak between 04:00 05:00 h. could serve as indicator species restoration conservation initiatives.
Abstract While hybridization and introgression can have a strong adaptive importance, it impede divergence of species. Quercus magnoliifolia Q. resinosa are two endemic oak species distributed across the Mexican highlands. These diverged ecological morphologically; however, no nuclear genetic differentiation is evident. In this study, we determined mechanisms that shape patterns variation establish role migration in evolutionary history these To do this, Bayesian approaches were used for...
Phylogeographical studies are fundamental for understanding factors that influence the spatial distribution of genetic lineages within species. Population expansions and contractions, shifts, climate changes among most important shaping compositions populations.
