Data from: Evolutionary radiations of Proteaceae are triggered by the interaction between traits and climates in open habitats
Aim: Ecologically driven diversification can create spectacular diversity in both species numbers and form. However, the prediction that the match between intrinsic (e.g. functional trait) and extrinsic (e.g. climatic niche) variables may lead to evolutionary radiation has not been critically tested
Data from: Evidence for enemy release and increased seed production and size for two invasive Australian acacias
Invasive plants are hypothesized to have higher fitness in introduced areas due to their release from pathogens and herbivores and the relocation of resources to reproduction. However, few studies have tested this hypothesis in native and introduced regions. A biogeographical approach is fundamental
Data from: Interannual bumble bee abundance is driven by indirect climate effects on floral resource phenology.
This is an archive of the data used in the publication: Ogilvie JE, Griffin SR, Gezon ZJ, Inouye BD, Underwood N, Inouye DW, Irwin RE. 2017. Interannual bumble bee abundance is driven by indirect climate effects on floral resource phenology. Ecology Letters, doi: 10.1111/ele.12854 DATA DESCRIPTION B
Data from: Observed forest sensitivity to climate implies large changes in 21st century North American forest growth
Predicting long-term trends in forest growth requires accurate characterisation of how the relationship between forest productivity and climatic stress varies across climatic regimes. Using a network of over two million tree-ring observations spanning North America and a space-for-time substitution
Supplement 1. Temperature and light data recorded at trap-nest sites, 2007–2010.
File List temp_data.txt light_data.txt Description Both files are tab-delimited text files. Temperatures (in degrees Celsius) were recorded in 2007–2008 using LogTag data-loggers, and in 2008–2010 using HOBO data-loggers. Light intensities (in lux) were recorded in 2008–2010 only, using HOBO data-lo

Data from: Biotic and abiotic variables influencing plant litter breakdown in streams: a global study
Plant litter breakdown is a key ecological process in terrestrial and freshwater ecosystems. Streams and rivers, in particular, have high rates of carbon dioxide evasion and they contribute substantially to global carbon fluxes. However, there is little information available on the relative roles of
Data from: Environmental controls on canopy foliar N distributions in a neotropical lowland forest
Distributions of foliar nutrients across forest canopies can give insight into their plant functional diversity and improve our understanding of biogeochemical cycling. We used airborne remote sensing and Partial Least Squares Regression (PLSR) to quantify canopy foliar nitrogen (N) across ~164 km2
Data from: A cost of being amicable in a hibernating marmot
Amicable social interactions can enhance fitness in many species, have negligible consequences for some, and reduce fitness in others. For yellow-bellied marmots (Marmota flaviventris), a facultatively social rodent species with demonstrable costs of social relationships during the active season, th
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
