The region of Valencia has a marked territorial duality: an urbanised, populated and high-income coastal line, and mountain and depressed inland rural areas. This territorial duality also derives in a functional duality, so that market and regulation drivers seem to assign rural areas specific roles for the provision of raw materials, energy, water, and the like. One of the clearest examples can be found in the design and development of the Wing Energy Plan passed by the Regional Government in 2001, which designated areas for the installation of windmills. However, this regulation has resulted in an outstanding emergence of associations that have organised at several levels (from the local to the national) as a...
These data identify the areas where final critical habitat has been mapped by the USFWS for plant species in the eastern United States. These data were compiled by the Conservation Biology Institute (CBI) from a series of individual shapefiles published by the USFWS (http://criticalhabitat.fws.gov/). For more information on the process for mapping the critical habitat for each species, please see the metadata for each species listed on the USFWS web site. Critical habitat designations have not been made for all listed endangered species. Where critical habitat has been mapped, this dataset only contains those species for which GIS datasets have been made publicly available. Other critical habitat maps exist for...
Costs of expanding the network of protected areas as a response to climate change in the Cape Floristic Region
The expansion of protected areas is a critical component of strategies to promote the continued existence of biodiversity (i.e., life at all levels of biological organization) as climate changes, but scientific, social, and economic uncertainties associated with climate change are some of the major obstacles preventing such expansion. New models of climate change and species distribution and new methods of conservation planning now make it possible to explore the uncertainties associated with climate changes and species responses. Yet few reliable estimates of the costs of expanding protected areas and methods for determining these costs exist, largely because of the many (and uncertain) determinants of these costs....
Patterns and mechanisms of plant diversity in forested ecosystems: Implications for forest management
Ornithological evaluation of the lower stream part of the alluvium of the River Morava (Slovak-Austrian frontier)
Final Report for "Climate-Change Vulnerability in the Pacific Northwest: A Comparison of Three Approaches"
Climate change is already affecting species in many ways. Because individual species respond to climate change differently, some will be adversely affected by climate change whereas others may benefit. Successfully managing species in a changing climate will require an understanding of which species will be most and least impacted by climate change. Although several approaches have been proposed for assessing the vulnerability of species to climate change, it is unclear whether these approaches are likely to produce similar results. In this study, we compared the relative vulnerabilities to climate change of 76 species of birds, mammals, amphibians, and trees based on three different approaches to assessing vulnerability....
Literature review and report: "Background Information for 'Agroforestry in the Climate of the Marshall Islands' Extension Website"
(1) This written report summarizes and synthesizes results of literature review, interviews, and workshops, providing the scientific basis for and extension strategies for the management recommendations provided in the "green website" [Data Input New Collection]. The report includes an addendum regarding reference bibliographies and a references list with citations. (2) Selected, unusual references that are not readily available online or through standard academic sources were collected by the project. (3) Selected photographs are retained by the project in electronic form.

Establishing a Baseline of Estuarine Submerged Aquatic Vegetation Resources Across Salinity Zones Within Coastal Areas of the Northern Gulf of Mexico
Probability of Whitebark Pine Mortality from Mountain Pine Beetle, 1997-2009, Northern Rockies Study Area
Estimates of the probability of mortality in whitebark pine from mountain pine beetles as determined from a logistic generalized additive model of the presence of mortality as functions of the number of trees killed last year, the percent whitebark pine in each cell, minimum winter temperature, average fall temperature, average April - Aug temperature, and cummulative current and previous year summer precipitation. Analysis was done at a 1 km grid cell resolution. Data are a list of points in comma separated text format. Point coordinates are the center of each 1 km grid cell.
Hawai'i Public Radio Feature with Pauk Krushelnycky: Shifting Climate Patterns Threatening Native Silverswords
A beautiful plant found only on Haleakala may become rarer. A recent study coauthored by UH researcher Paul Krushelnycky shows changing climate patterns allowing fog and rain to reach higher elevations are threatening the plant but he cautions all is not lost. He joined us in our studio to tell us more. Paul is currently Assistant Researcher, at the College of Tropical Agriculture and Human Resources at the University of Hawaii in Manoa.
Abstract (from http://climatechangeresponses.biomedcentral.com/articles/10.1186/s40665-016-0015-2): Background Detailed assessments of species responses to climate change are uncommon, owing to the limited nature of most ecological and local climate data sets. Exceptions, such as the case of the Haleakalā silversword, can provide important insights into the complexity of biological responses to changing climate conditions. We present a time series of decadal population censuses, combined with a pair of early population projections, which together span the past 80 years of demographic history for this alpine plant. Results The time series suggests a strong population recovery from the 1930s through the 1980s, likely...
An Assessment of Diurnal and Seasonal Cloud Cover Changes over the Hawaiian Islands Using Terra and Aqua MODIS
Abstract (from http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-15-0088.1): A comprehensive understanding of the spatial, seasonal, and diurnal patterns in cloud cover frequency over the Hawaiian Islands was developed using high-resolution image data from the National Aeronautics and Space Administration’s Moderate Resolution Imaging Spectroradiometer (MODIS) sensors aboard the Terra and Aqua satellites. The Terra and Aqua MODIS cloud mask products, which provide the confidence that a given 1-km pixel is unobstructed by cloud, were obtained for the entire MODIS time series (10-plus years) over the main Hawaiian Islands. Monthly statistics were generated from the daily cloud mask data, including mean cloud cover...
