Data from: Near infrared spectroscopy (NIRS) predicts non-structural carbohydrate concentrations in different tissue types of a broad range of tree speciesJorge A. Ramirez, Juan M. Posada, I. Tanya Handa, Günter Hoch, Michael Vohland, Christian Messier & Björn Reu
1. The allocation of non-structural carbohydrates (NSCs) to reserves constitutes an important physiological mechanism associated with tree growth and survival. However, procedures for measuring NSC in plant tissue are expensive and time-consuming. Near-infrared spectroscopy (NIRS) is a high-throughput technology that has the potential to infer the concentration of organic constituents for a large number of samples in a rapid and inexpensive way based on empirical calibrations with chemical analysis. 2. The main objectives of this...
Data from: Edge influence on vegetation at natural and anthropogenic edges of boreal forests in Canada and FennoscandiaKaren A. Harper, S. Ellen Macdonald, Michael S. Mayerhofer, Shekhar R. Biswas, Per-Anders Esseen, Kristoffer Hylander, Katherine J. Stewart, Azim U. Mallik, Pierre Drapeau, Bengt-Gunnar Jonsson, Daniel Lesieur, Jari Kouki & Yves Bergeron
1. Although anthropogenic edges are an important consequence of timber harvesting, edges due to natural disturbances or landscape heterogeneity are also common. Forest edges have been well-studied in temperate and tropical forests, but less so in less productive, disturbance-adapted boreal forests. 2. We synthesized data on forest vegetation at edges of boreal forests and compared edge influence among edge types (fire, cut, lake/wetland; old vs. young), forest types (broadleaf vs. coniferous) and geographic regions. Our...
Data from: Rapid evolutionary responses of life history traits to different experimentally-induced pollution in Caenorhabditis elegansMorgan Dutilleul, Jean-Marc Bonzom, Catherine Lecomte, Benoit Goussen, Fabrice Daian, Simon Galas & Denis Réale
Background Anthropogenic disturbances can lead to intense selection pressures on traits and very rapid evolutionary changes. Evolutionary responses to environmental changes, in turn, reflect changes in the genetic structure of the traits, accompanied by a reduction of evolutionary potential of the populations under selection. Assessing the effects of pollutants on the evolutionary responses and on the genetic structure of populations is thus important to understanding the mechanisms that entail specialization to novel environmental conditions or...
Data from: The interaction between the spatial distribution of resource patches and population density: consequences for intra-specific growth and morphologyBailey Jacobson, James W.A. Grant, Pedro R. Peres-Neto & James W. A. Grant
1. How individuals within a population distribute themselves across resource patches of varying quality has been an important focus of ecological theory. The ideal free distribution predicts equal fitness amongst individuals in a 1 : 1 ratio with resources, whereas resource defence theory predicts different degrees of monopolization (fitness variance) as a function of temporal and spatial resource clumping and population density. 2. One overlooked landscape characteristic is the spatial distribution of resource patches, altering...
