Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense also affects tolerance to abiotic stressors. Urban-rural gradients associated with the of clines 47% throughout world. Variation strength was explained changes drought stress and vegetation cover varied...
• Premise of the study: Wild populations domesticated species constitute a genetic reservoir and are fundamental to evolutionary potential species. papaya (Carica papaya) is rare, short-lived, gap-colonizing, dioecious tree that persists in forest by continuous dispersal. Theoretically, these life-history characteristics render wild highly susceptible habitat fragmentation, with anticipated negative effects on its gene pool. Further, dioecy may cause founder generate local biases sex ratio,...
Few studies have evaluated the genetic structure and evolutionary history of wild varieties important crop species. The papaya (Carica papaya) is a key element early successional tropical sub-tropical forests in Mexico, constitutes reservoir for potential In this study we aimed to determine how diverse structured variability populations C. Northern Mesoamerica. Moreover, assessed if coincide with hypothetized (1) pre-Pleistocene events (Isthmus Tehuantepec sinking), (2) Pleistocene refugia...
Abstract The spatial signature of microevolutionary processes structuring genetic variation may play an important role in the detection loci under selection. However, location samples has not yet been used to quantify this. Here, we present a new two‐step method outlier at individual and deme levels using power spectrum Moran eigenvector maps ( MEM ). quantifies how variable, such as frequency allele SNP locus, is distributed across range scales defined by eigenvectors. first step (Moran...
We evaluated the role of gene flow and wild-crop introgression on structure genetic diversity Lima bean ( Phaseolus lunatus ) in Yucatan Peninsula, an important Mesoamerican area for this crop, using a genotyping-by-sequencing approach (15,168 SNP markers) two scales. At local scale, STRUCTURE NGSEP analyses showed predominantly crop-to-wild introgression, but also evidence bidirectional wild-weedy-crop complexes studied (Itzinté Dzitnup). The ABBA-BABA tests higher Itzinté (the older...
Premise Recent phylogeographic work suggests the existence of latitudinal gradients in genetic diversity northern Mexican plants, but very few studies have examined plants Chihuahuan Desert. Tidestromia lanuginosa is a morphologically variable annual species whose distribution includes Desert Region. Here we undertook analyses chloroplast loci this to test whether and differentiation populations T. change along gradient higher Coahuila, consistent with ideas lower plant community turnover...
El sistema tradicional milpa, manejado mayormente bajo temporal en Yucatán, México; es importante a nivel social, biológico y ambiental. La milpa ha perdurado través del tiempo por los conocimientos ancestrales transmitidos generaciones. Por lo anterior, el objetivo fue conocer las estrategias de manejo realizadas milperos su actividad agrícola la conservación diversidad biológica. investigación se efectuó comunidad maya Xoy, Peto, Yucatán aplicando encuestas semiestructuradas al 30%...
Abstract Background Restoration practices usually emphasize on the structural part of biodiversity; also, most studies have focused plants and very few been conducted arthropods its function after restoration. The Pedregal de San Angel Ecological Reserve (PSAER) is a protected area immersed in Mexico City it has drastically affected by different anthropogenic disturbances. aim this study was to compare relative diversity, richness, abundance species level identification, but also composition...
Abstract Shifts in phenotypes derived from the domestication syndromes impact plant performance but may also affect interactions with other species community ( e.g. mutualists and antagonists). Moreover, plantations often differ natural conditions experienced by wild relatives of cultivated plants, potentially altering nature ecological interactions. However, apart herbivory, little is known about how cultivation practices e.g . insecticide application) can modify multiple simultaneously...
Abstract To cope with the limiting light conditions in rain forest understory, many tropical tree species have evolved large seeds that provide emerging seedlings nutritional reserves. Habitat fragmentation might change adaptive value of seed size by modifying biotic and physical understory. We experimentally assessed potential to alter how mass affects seedling survival, vigor, attack natural enemies Nectandra ambigens . Seeds from different mother trees (families) were individually weighed...
Theory predicts that habitat fragmentation, by reducing population size and increasing isolation among remnant populations, can alter their genetic diversity structure. A cascade of effects is expected: drift inbreeding after a bottleneck, changes in biotic interactions may affect, as the case plants, pollen dynamics, mating system, reproductive success. The detection contemporary fragmentation on structure populations are conditioned magnitude change, given few number generations since...
Background: Plant domestication is a continuous, multidirectional process that directed via plant selection and management. In the current study we use Piper auritum, an aromatic frequently used in Mexican cuisine for medicinal purpose, to characterize level using information about its cultural relevance, management practices leaf traits differentiation managed ruderal populations. Questions: What of auritum? Are there any morphological or phytochemical differences between home garden...
