Publication Data for Barner et al. Journal of Ecology Manuscript: The complex net effect of reciprocal interactions and recruitment facilitation maintains an intertidal kelp community

Allison Barner, Sally Hacker, Bruce Menge & Karina Nielsen
Publication data for Barner et al. Journal of Ecology Manuscript: The complex net effect of reciprocal interactions and recruitment facilitation maintains an intertidal kelp community. In this study, we conducted two different removal experiments to quantify species interactions between the canopy kelp Saccharina sessilis and its understorey. Coupled with observational data on kelp recruitment, we determined the whole-community species interaction network for a rocky intertidal macroalgal canopy-understorey assemblage. The data here include the observational recruitment...

California Drought- Annual scPDSI 1896 to 2013

Rocky Mountain Research Station & Sparkle Malone
We used remotely sensed self calibrating Palmer Drought Severity Index (scPDSI), made available through the Western Regional Climate Center (www.wrcc.dri.edu/wwdt/data/PRISM/scpdsi/). The scPDSI ranges from -5.0 to 5.0. The number shows the magnitude and the sign denotes (+) wetter than average or (-) drier than average conditions for a location based on historical climate and sensitivity to changes in water availability. Absolute values greater than 4 represent extreme conditions and unlike earlier versions of the PDSI,...

Testing Amazon Transitional Forest Leaf Flammability: Combustion Experiment Temperature Readings (2015)

Amy Parsons & Jennifer Balch
Intensifying land use practices and global climate change are leading to increased forest fragmentation and more severe droughts in the southeastern transitional forests of the Brazilian Amazon. The combination of land use and droughts has increased fire frequency, intensity, and extent in the region. Various plant traits can either limit or promote flammability, as demonstrated in many seasonally dry environments (e.g. Mediterranean shrublands), which are home to species that are adapted to frequent fire. However,...

Bicknell's Thrush (Catharus bicknelli) Presence-absence Surveys in New England and New York, 1992-1995

Kent McFarland, Christopher Rimmer & Jon Atwood
We conducted presence-absence surveys for Bicknell’s Thrush (Catharus bicknelli) with the help of citizen scientists in Maine, Massachusetts, New Hampshire, New York, and Vermont during the 1992-1995 breeding seasons. The species was found at 234 sites, of which 225 (96%) were dominated by varying mixtures of balsam fir (Abies balsamea) and red spruce (Picea rub- ens). Ninety-one percent of the occupied sites were 2915 m (3000 ft) in elevation. Size of occupied habitat patches was...

Cumulative human impacts: change in pressures and cumulative impact (2008 to 2013)

Benjamin Halpern, Melanie Frazier, John Potapenko, Kenneth Casey, Kellee Koenig, Catherine Longo, Julia Lowndes, Cotton Rockwood, Elizabeth Selig, Kimberly Selkoe & Shaun Walbridge
This is a portion of the data used to calculate 2008 and 2013 cumulative human impacts in: Halpern et al. 2015. Spatial and temporal changes in cumulative human impacts on the world's ocean. Seven data packages are available for this project: (1) supplementary data (habitat data and other files); (2) raw stressor data (2008 and 2013); (3) stressor data rescaled by one time period (2008 and 2013, scaled from 0-1); (4) stressor data rescaled by...

California Mean Annual CUE (2002-2013)

Rocky Mountain Research Station & Sparkle Malone
This data set was developed using MODIS (land cover, leaf area index (LAI), and gross primary productivity (GPP)), for the state of California from 2002 to 2013. Satellite imagery was re-sampled to 4km resolution using bilinear methods of interpolation and re-projected to UTM WGS84 using the R library raster.

Camera trap activity record in front of Allanblackia stuhlmannii seeds February-April 2011 in the Amani Nature Reserve, Tanzania

University Of Illinois At Chicago & Carrie Seltzer
Camera traps were used in 12 different 50x50 m submontane rainforest plots in the Amani Nature Reserve, Tanzania. The purpose of the camera traps was to record rodent activity and interactions with Allanblackia stuhlmannii seeds. Other incidental animal activity was also recorded. For each photo, animal presence was noted using tags added to the photo metadata, which was then parsed and summarized here. This does not contain the photos themselves, but the summary data on...

Puerto Rico Bicknell's Thrush Surveys, 2014

Christopher Rimmer & John Lloyd
A predictive model of the distribution of wintering habitat for Bicknell’s Thrush (Catharus bicknelli) (McFarland et al. 2013) indicated that a considerable extent of potentially suitable habitat for Bicknell's Thrush exists in the central highlands of Puerto Rico. This region has never been surveyed for the species. To test the predictions of the winter habitat model, and to better clarify the species’ distribution during the winter, we conducted surveys in areas throughout Puerto Rico identified...

Male tenure length and variance in lifetime reproductive success recorded for mammals

Data from: Producer diversity enhances consumer stability in a benthic marine community

Aaron Ramus & Zachary Long
1. The diversity of many communities is changing due to local extinctions and invasions. Understanding the consequences of these changes is vital to their successful conservation, yet few studies have experimentally investigated how producer diversity affects the stability of higher trophic levels. Here we show that producer diversity, when manipulated as the only independent variable in the presence of natural top-down forces, increases the stability of consumer abundance, biomass, and diversity in a benthic marine...

Precipitation in California

Rocky Mountain Research Station & Sparkle Malone
This data set was developed using PRISM mean annual precipitation data from 2002 to 2013. Scenes were re-sampled to 4km using bilinear methods of interpolation and re-projected to UTM WGS84 using the R library raster. Mean, standard deviation of annual precipitation and the variance in annual precipitation are included in this data set.

Fruit fall of Allanblackia stuhlmannii monitored February 2011-January 2012 in the Amani Nature Reserve, Tanzania

University Of Illinois At Chicago & Carrie Seltzer
Fruit fall of Allanblackia stuhlmannii (Clusiaceae), a rainforest canopy tree with large fruits, was monitored inside 12 different 50x50 m submontane rainforest plots in the Amani Nature Reserve, Tanzania. Each time a plot was visited, newly fallen fruits were marked, counted, and categorized based on ripeness and condition. The purpose of these data was to record background fruit abundance (as a proxy for seed abundance) as part of a study following A. stuhlmannii seed fate.
