Data for Lynn et al. “Soil microbes that may accompany climate warming increase alpine plant production”
Climate change is causing species with non-overlapping ranges to come in contact, and a key challenge is to predict the consequences of such species re-shuffling. Experiments on plants have focused largely on novel competitive interactions; other species interactions, such as plant-microbe symbioses
Plant composition data from 67 grassland sites of the Upper Gunnison Basin, CO, USA, 2014
Here, we deposit data from a vegetation survey conducted in 2014. The data was collected to document current vegetation patterns in the region, parameterize species distribution models, and assess community turnover in flower color. The survey was conducted in the Upper Gunnison Basin and the enviro
The Sagebrush Biome Range Extent, as Derived from Classified Landsat Imagery
This feature estimates the geographic extent of the sagebrush biome in the United States. It was created for the Western Association of Fish and Wildlife Agency's (WAFWA) Sagebrush Conservation Strategy publication as a visual for the schematic figures. This layer does not represent the realized dis
Pocket gopher (<i>Thomomys talpoides</i>) soil disturbance peaks at mid-elevation and is associated with air temperature, forb cover, and plant diversity
Burrowing mammals can be ecosystem engineers by increasing soil aeration and erosion and altering the structure of plant communities. Studies that characterize the constraints on the distributions of fossorial mammal disturbances to soil can help predict changes in ecosystem engineering under future
Fruit/seed traits and phenology of trees in Ranomafana National Park, Madagascar
This dataset contains information on fruit/seed traits of plants in Ranomafana National Park, Madagascar as well as a summary of their fruiting phenology for the period of July 2012 - June 2014.
Data from: Seed size predicts community composition and carbon storage potential of tree communities in rainforest fragments in India’s Western Ghats
Fragmentation is ubiquitous across tropical forests and drives marked shifts in tree community composition by differentially affecting species’ dispersal, establishment and survival. Such compositional shifts can potentially alter ecosystem-level properties such as above-ground carbon storage, but o
Data from: Early snowmelt projected to cause population decline in a subalpine plant
How climate change influences the dynamics of plant populations is not well understood, as few plant studies have measured responses of vital rates to climatic variables and modeled the impact on population growth. I used 25 years of demographic data to analyze how survival, growth, and fecundity re
Data from: Landscape pivot points and responses to water balance in national parks of the southwest U.S.
1. A recent drying trend that is expected to continue in the southwestern U.S. underscores the need for site-specific and near real-time understanding of vegetation vulnerability so that land management actions can be implemented at the right time and place. 2. We related the annual integrated norma
Data from: The individual and combined effects of snowmelt timing and frost exposure on the reproductive success of montane forbs
1. Changes from historic weather patterns have affected the phenology of many organisms worldwide. Altered phenology can introduce organisms to novel abiotic conditions during growth and modify species interactions, both of which could drive changes in reproduction. 2. We explored how climate change
pivot points and responses by polygon
Data from: Thoma, D.P., S.M. Munson D.L. Witwicki 2018. Landscape pivot points and responses to water balance in national parks of the southwest U.S. Contact: David Thoma Dave_thoma@nps.gov 406-994-7725 These data are the polygon attributes and linear regression coefficients of iNDVI and water balan
Data from: Transgenerational and within-generation plasticity in response to climate change: insights from a manipulative field experiment across an elevational gradient
Parental environmental effects, or transgenerational plasticity, can influence an individual’s phenotype or fitness, yet remain underexplored in the context of global change. Using the perennial self-pollinating plant Boechera stricta, we explored the effects of climate change on transgenerational a
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: How persistent are the impacts of logging roads on Central African forest vegetation?
1. Logging roads can trigger tropical forest degradation by reducing the integrity of the ecosystem and providing access for encroachment. Therefore, road-management is crucial in reconciling selective logging and biodiversity conservation. Most logging roads are abandoned after timber harvesting, h
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: Vegetation as self-adaptive coastal protection: reduction of current velocity and morphologic plasticity of a brackish marsh pioneer
By reducing current velocity, tidal marsh vegetation can diminish storm surges and storm waves. Conversely, currents often exert high mechanical stresses onto the plants and hence affect vegetation structure and plant characteristics. In our study, we aim at analysing this interaction from both angl
Data from: The mechanical defence advantage of small seeds
Seed size and toughness affect seed predators, and size-dependent investment in mechanical defence could affect relationships between seed size and predation. We tested how seed toughness and mechanical defence traits (tissue density and protective tissue content) are related to seed size among trop
Data from: Is plant fitness proportional to seed set? An experiment and a spatial model
Individual differences in fecundity often serve as proxies for differences in overall fitness, especially when it is difficult to track the fate of an individual's offspring to reproductive maturity. Using fecundity may be biased, however, if density-dependent interactions between siblings affect su
Data from: Facilitated exploitation of pollination mutualisms: fitness consequences for plants
Mutualisms are only rarely one-to-one interactions: each species generally interacts with multiple mutualists. Exploitation is ubiquitous in mutualisms, and we would therefore expect that each mutualist interacts with multiple exploiters as well. Exploiter species may also interact with one another.
Focal female data
Measurements of focal females, including proportion of flowers that successfully produced seed. See README.txt for column descriptions.
Focal female locations 2014
This .zip archive contains a shapefile (including .shp, .shx, .dbf, and .prj components) that describes the locations of focal females used in 2014 in the study of the effect of neighborhood operational sex ratio on seed set rates in Valeriana edulis.
