Experimental frost damage data for eight subalpine plant species
This file contains data on the frost damage of eight subalpine plant species from the Rocky Mountains of Colorado (USA). These frost damage data can be used to calculate frost sensitivity for each species. Frost damage of plant tissue was determined after specimen were exposed to experimental temper
Data from: Tropical trees in a wind-exposed island ecosystem: height-diameter allometry and size at onset of maturity
1. Tropical tree species adapted to high wind environments might be expected to differ systematically in terms of stem allometry and life-history patterns, as compared with species found in less windy forests. We quantified height-diameter (H-D) allometries and relative size at onset of maturity (RS
Data from: Genome-wide scans reveal cryptic population structure in a dry-adapted eucalypt
Genome-wide DArTseq scans of 268 individuals of Eucalyptus salubris, distributed along an aridity gradient in southwestern Australia, revealed cryptic population structure that appears to signal hitherto unappreciated ecotypic differentiation and barriers to gene flow. Genome-wide scans were underta
Data from: Globally, functional traits are weak predictors of juvenile tree growth, and we do not know why
1. Plant functional traits, in particular specific leaf area (SLA), wood density and seed mass, are often good predictors of individual tree growth rates within communities. Individuals and species with high SLA, low wood density and small seeds tend to have faster growth rates. 2. If community-leve
Data from: Deciphering the adjustment between environment and life history in annuals: lessons from a geographically-explicit approach in Arabidopsis thaliana
The role that different life-history traits may have in the process of adaptation caused by divergent selection can be assessed by using extensive collections of geographically-explicit populations. This is because adaptive phenotypic variation shifts gradually across space as a result of the geogra
Data from: Pinus ponderosa alters nitrogen dynamics and diminishes the climate footprint in natural ecosystems of Patagonia
1. Evaluating climate effects on plant-soil interactions in terrestrial ecosystems remains challenging due to the fact that floristic composition co-varies with climate, particularly along rainfall gradients. It is difficult to separate effects of precipitation per se from those mediated indirectly
Data from: Crown asymmetry in high latitude forests: disentangling the directional effects of tree competition and solar radiation
Light foraging by trees is a fundamental process shaping forest communities. In heterogeneous light environments this behavior is expressed as plasticity of tree growth and the development of structural asymmetries. We studied the relative influence of neighborhood structure and directional solar ra
Data from: Three keys to the radiation of angiosperms into freezing environments
Data from: Effects of tree architecture on pollen dispersal and mating patterns in Abies pinsapo Boiss. (Pinaceae)
Plant architecture is crucial to pollination and mating in wind pollinated species. We investigate the effect of crown architecture on pollen dispersal, mating system and offspring quality, combining phenotypic and genotypic analyses in a low-density population of the endangered species Abies pinsap
Areas of Weakly Anomalous to Anomalous Surface Temperature in Alamosa and Saguache Counties, Colorado, as Identified from ASTER Thermal Data
This "Weakly Anomalous to Anomalous Surface Temperature" dataset differs from the "Anomalous Surface Temperature" dataset for this county (another remotely sensed CIRES product) by showing areas of modeled temperatures between 1o and 2o above the mean, as opposed to the greater than 2o temperatures
Surface Temperature Anomalies Derived from Night Time ASTER Data Corrected for Solar and Topographic Effects, Alamosa and Saguache Counties, Colorado
This map shows areas of anomalous surface temperature in Alamosa and Saguache Counties identified from ASTER thermal data and spatial based insolation model. The temperature is calculated using the Emissivity Normalization Algorithm that separate temperature from emissivity. The incoming solar radia

Seed dispersal in four Rocky Mountain herbaceous perennials: wind dispersal in <i>Erythronium grandiflorum</i> and ant dispersal in <i>Corydalis aurea</i>, <i>Delphinium nelsonii</i>, <i>Viola nuttalli</i>
Thermal Influences on the Activity and Energetics of Yellow-Bellied Marmots (Marmota flaviventris)
Oxygen consumption and body temperature in yellow-bellied marmot populations from montane-mesic and lowland-xeric environments
Yellow-bellied marmots minimize thermoregulatory costs by concentrating activity at times when the microclimate is favorable, by tolerating hyperthermia at high TA in the field, and by having a conductance lower than that predicted from body size.
Possible effects of acidic deposition on a Rocky Mountain population of the tiger salamander <i>Ambystoma tigrinum</i>
Abstract: To investigate possible biological effects of acidic deposition in the western United States, we performed population censuses and dose‐response experiments at a subalpine watershed in the Rocky Mountains of Colorado, An adult tiger salamander (Ambystoma tigrinum nebulosum) population decl
