The mechanisms of drought resistance that allow plants to successfully establish at different stages secondary succession in tropical dry forests are not well understood. We characterized early and late-successional species tested whether risk differs across sites successional stages, differ experimentally imposed soil drought. microenvironment was warmer drier than mature forest. Nevertheless, groups did Late-successional resisted through two independent mechanisms: high xylem embolism, or...
Summary Successional gradients are ubiquitous in nature, yet few studies have systematically examined the evolutionary origins of taxa that specialize at different successional stages. Here we quantify habitat specialization Neotropical forest trees and evaluate its lability along a precipitation gradient. Theoretically, should be more evolutionarily conserved wet forests than dry due to extreme microenvironmental differentiation between early late‐successional stages forest. We applied...
In seasonal plant communities where water availability changes dramatically both between and within seasons, understanding the mechanisms that enable plants to exploit pulses survive drought periods is crucial. By measuring rates of physiological processes, we examined trade-off exploitation tolerance among seedlings trees a tropical dry forest, identified biophysical traits most closely associated with water-use strategies. We also explored whether early late secondary successional species...
ABSTRACT A common observation in tropical dry forests is the habitat preference of tree species along spatial soil water gradients. This pattern partitioning might be a result differentiation their strategy for using water, with competing functions such as maximizing exploitation and tolerating stress. We tested whether from drier conditions exhibited tolerance compared that wet‐habitat species. In comparison 12 morphophysiological traits seedlings 10 closely related pairs, we explored what...
Oak species (Fagaceae: Quercus) differ in their distribution at the landscape scale, specializing to a certain portion of environmental gradients. This suggests that functional differentiation favors habitat partitioning among closely related species. To elucidate mechanisms coexistence oak forests, we explored patterns interspecific variation traits involved water-use strategies. We tested hypothesis segregate along key trade-offs between xylem hydraulic efficiency and safety, safety...
Increasing disturbance events (forest fires, windstorms, pest outbreaks) associated with climate change are creating new ecological restoration challenges. Here, we examine the utility of assisted migration in combination naturally established nurse plants order to improve success afforestation Abies religiosa (sacred fir), overwintering host Monarch butterfly (Danaus plexippus). We high-elevation A. provenance field tests at two sites (Las Palomas and Los Ailes) core areas Butterfly...
Abstract Background Rhizosphere microbiomes are fundamental for plant health, development, and productivity, but can be altered by the incidence of soil-borne pathogens. The dysbiosis (disturbance microbiome structure healthy plants) caused these pathogens, combined with recruitment beneficial microorganisms diseased plant, may cause shifts in rhizosphere during infection process. These likely to associated changes metabolic profile, as biochemical dialog, or crosstalk, between host plants...
Elucidating the factors determining plant distribution is still on discussion. It has been stated that mostly determined by environmental factors, but evidence whether this or other processes are determinants remains inconclusive. In present study, we hypothesized oak species differ in their distribution, which might be influence environment. Particularly, explored: i) patterns of Quercus at a landscape scale; ii) climatic, soil and topographic determine iii) degree association between...
The study of above- and below-ground organ plant coordination is crucial for understanding the biophysical constraints trade-offs involved in species’ performance under different environmental conditions. Environmental stress expected to increase on species trait combinations, resulting stronger among organs acquisition processing most limiting resource. To test this hypothesis, we compared combinations 94 tree seedling from two tropical forest systems Mexico: dry moist. In general, that...
Abstract Tropical dry forests are environmentally complex ecosystems with highly heterogeneous water availability, such that distinctive plant communities found in contrasting habitats close proximity to each other. This leads the question of how resource heterogeneity has led functional among communities. One hypothesis is main trade‐offs and size space should diverge between differ their most limiting resource. To test this, we compared aboveground belowground traits saplings 33 dominant...
In many terrestrial habitats, plants experience temporal heterogeneity in water availability both at the intra and inter annual scales, creating dry-wet pulse scenarios. This variability imposes two concomitant challenges for plants: surviving droughts efficiently utilizing when it becomes available, whose responses are closely interconnected. To date, most studies have focused on response to drought following static designs that do not consider consequences of repeated transitions from one...
Abstract Aim New protected areas should consider safeguarding high conservation value sites based on multiple criteria and not just the presence of a single endangered or charismatic species. However, extent to which complementary coincide is usually unknown. We use case Guaiacum sanctum (Zygopyllaceae), an timber tree species, explore whether protection forests where this species most abundant would meet other goals, such as capturing regional plant biodiversity, protecting...
Abstract Aims Mechanisms of plant drought resistance include both tolerance and avoidance. Xylem vulnerability to embolism turgor loss point are considered traits that confer tolerance, while leaf abscission deciduousness characterizes the avoidance strategy. While these mechanisms thought trade-off expressing a continuum among species, little is known on how variation in timing duration shedding response affect relationship between xylem tolerance. In present study, we explored extent which...
Antecedentes y Objetivos: Los disturbios antropogénicos o naturales pueden ser tan fuertes que para recuperar sitios degradados se requiere de intervención. Una forma facilitar el proceso recuperación es mediante uso especies nativas adaptadas al ambiente local, pero aún existe desconocimiento sobre su desempeño. Asimismo, establecimiento interacciones con hongos micorrícicos puede contribuir a tener un mayor éxito en supervivencia crecimiento empleadas la restauración. El arbusto Tecoma...
Connectivity is a landscape property that promotes gene flow between organisms located in different patches of habitat and provides way to reduce loss by maintaining flux through the landscape; it an important factor for conservation decisions. In this study, we evaluated structural functional connectivity among 510 oak forest remnants basin central Mexico modeling potential distribution seven species inhabit it. The was estimated graph theory. Distribution models all had good level...
The study of the basic biology panchronic species could help understand their persistence through geological time. One least studied is Baronia brevicornis Salvin (Lepidoptera: Papilionidae), oldest known butterfly endemic to Mexico. Here we report on our findings from studying a population B. in Sierra de Huautla, Morelos, for 3 years. In this identified male and female color morphs, making it perhaps most complex polymorphism described yet species. We found balanced sex ratio newly emerged...
Background: Seedling establishment depends on the quality of seeds and environmental conditions. Differential biomass allocation in emergent seedlings probably constitutes a relevant adaptive response populations along gradients.
 Questions: Are there differences seed mass among Prosopis laevigata populations? Is this variation correlated with variables?
