The National Eutrophication Survey: lake characteristics and historical nutrient concentrations

Joseph Stachelek, Chanse Ford, Dustin Kincaid, Katelyn King, Heather Miller & Ryan Nagelkirk
Historical ecological surveys are an important source of baseline information to provide context for contemporary research, yet many of these records are not preserved in a way to ensure their long-term usability. The National Eutrophication Survey database is currently only available as portable document files (PDF) scanned from printed records with no embedded character information. This limits its searchability and the ability of current and future scientists to systematically evaluate its contents. The data was...

SCR_Aerial_SantaCruzIslandNorth_10142012_Imagery

James Reed
This raster dataset was developed for the Sea Grant South Coast MPA Baseline Program as part of the project “Nearshore Substrate Mapping and Change Analysis using Historical and Concurrent Multispectral Imagery” (#R/MPA 30 10-049). The study region is the South Coast Region (SCR). Imagery was acquired on October 14, 2012 at a spatial resolution of 0.3 meters using a Microsoft UltraCam-X digital camera acquiring in the red, green, blue and near-infrared bands. Information on the...

Mean climatological and baseline nearshore ocean conditions

Eric Bjorkstedt
Data reported in this package capture information on nearshore temperature, ocean structure, chlorophyll concentration, sea level, currents, and relative exposure to freshwater as a function of latitude as part of the oceanographic context for MPAs in the North Coast Study Region during the period prior to (2003-2013) and during (2014-2016) the baseline study period.

Invertebrate Biodiversity

Frank Shaughnessy
Goals of this baseline study were to describe biodiversity and target species (abundance, size) in two estuaries from the northern bioregion and two from the southern bioregion of the North Coast MPA Region. Macrophytes, invertebrates and fish were enumerated from two sites within each estuary on June 2014, January 2015, June 2015, January 2016 and June 2016. This Package contains a table of all the presence-absence data for all of the invertebrates that were found...

Surveys of Forest Birds on Puerto Rico, 2015

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...

Food webs for paper

Joshua Thoresen
Burrowing seabirds that nest on islands transfer nutrients from the sea, disturb the soil through burrowing, damage tree foliage when landing, and thereby modify the surface litter. However, seabirds are in decline worldwide, as are their community- and ecosystem-level impacts, primarily due to invasive predatory mammals. The direct and indirect effects of seabird decline on communities and ecosystems are inherently complex. Here we employed network analysis, as a means of simplifying ecological complexity, to better...
