Prosopis laevigata microsatellite and sequence alignment data

Antonio González-Rodríguez, Gonzalo Contreras-Negrete, Luis Letelier & Javier Piña-Torres
Patterns of genetic and phylogeographic structure and recent population history of plant species in the Mexican arid zones has been scarcely investigated. Prosopis laevigata is the most widely spread species of mesquite in Mexico, with extensive populations in the arid and semi-arid zones of the central and northern plateaus and scattered presence in southern Mexico. We evaluated the genetic and phylogeographic structure of this species to infer its recent demographic history. We genotyped six nuclear...

How to cope with drought and not die trying: drought acclimation across tree species with contrasting niche breadth

Alex Fajardo & Frida Piper
Worldwide drought events have been reported to cause tree growth decline and mortality, thus altering the carbon (C) balance of forest ecosystems. While most of the attention has been focused on the physiological mechanisms associated with drought-induced tree responses of a few species at specific locations, the ecological attributes of these species, like their niche breadth, may be also important in determining species’ sensitivity or resilience to drought. We postulated that wide-niche breadth tree species...

Phenotypic plasticity may mediate habitat filtering in a forest edge community

Ernesto Gianoli & Víctor Escobedo
A key process determining community assembly is habitat filtering, which reduces the range of trait values and thus leads to trait convergence. Habitat filtering is often assumed to involve a reduction in species richness, but such trait convergence could also result from phenotypic plasticity. By allowing more species in the community to show the “right” phenotype and pass the filter, phenotypic plasticity could maintain species richness despite trait convergence. If phenotypic plasticity plays this role,...

Interactive effects of shading and disturbance on plant invasion in an arid shrubland: assembly processes and CSR-strategies

Víctor Escobedo, Rodrigo Rios & Ernesto Gianoli
Disturbance by small mammals and shrub canopies are ecological factors typical of arid ecosystems that may influence plant invasion through environmental and community changes. Whereas disturbance beneath shrub canopies may promote invasion by removing dominant species, disturbance in open areas may hinder plant invasion by increasing environmental harshness. However, we are unaware of studies explicitly addressing the interactive effects of disturbance by mammals and shading by shrubs on community assembly processes to understand plant invasion....

Data from: Fine-scale spatial associations between functional traits and tree growth

Alex Fajardo & Eduardo Velázquez
This data set relates to a 40x60 m2 stem-mapped plot that was established in a temperate rainforest of southern Chile. It contains data for each individual stem located within the plot. Each individual is characterized by a species code, diameter at breast height (dbh, 1.35 m), diameter at coring height (dch, ca. 30 cm), x and y coordinates, basal area index of the last 10 years (bai, cm2), and growth efficiency (ge, cm2/cm2).
