Studies of forests and urban forest ecosystems have documented the various biophysical and socioeconomic correlates of carbon storage. Tree cover in particular is often used as a determinant of carbon storage for local and national level urban forest assessments. However, the relationships among variables describing the biophysical and socioeconomic environment and carbon are not simple statist...

The reflected radiance in topographically complex areas is severely affected by variations in topography; thus, topographic correction is considered a necessary pre-processing step when retrieving biophysical variables from these images. We assessed the performance of five topographic corrections: (i) C correction (C), (ii) Minnaert, (iii) Sun Canopy Sensor (SCS), (iv) SCS + C and (v) the Proce...

OBJECTIVE Global incidence of contrast-induced nephropathy (CIN) is 2-5%, but a recent Kenyan study highlighted a local incidence of 12-14% without offering an explanation for the higher incidence. This study proposes that inflammatory states confer a higher relative risk for development of CIN. Our objective was to determine the risk of developing CIN given the presence of an inflammatory stat...

Conservation of tropical biodiversity in agricultural landscapes has become more important as the area covered by natural ecosystems decreases. We analyzed the effects of local livelihoods, cooperative types, and selected biophysical variables (elevation, slope, percent shade, distance to the forest, coffee density, and coffee age) on tree biodiversity in shade coffee cooperatives of El Salvado...

Neotropical forested landscapes have become agricultural areas and human settlements, causing forest fragmentation, land degradation, habitat loss. Nonetheless, complex tree cover loss recovery processes may occur even while urban expand. Biophysical, social, political, economic drivers influence or over time. This study analyzes land-use change dynamics in peri-urban the western sector of Xala...

The Southeast Alaska Coastal Monitoring (SECM) project has been sampling juvenile salmon (Oncorhynchus spp.) and associated biophysical parameters in northern Southeast Alaska (SEAK) annually since 1997 to better understand effects of environmental change on salmon production. A pragmatic application of the annual sampling effort is to forecast the abundance of adult salmon returns in subsequen...

Remote sensing bears the potential to provide quantitative information of agricultural crops instantaneously and of a certain regional extent. Estimates of crop growth which are used for crop yield prediction, and timing of forthcoming harvest are important in agricultural planning and policy making. For non-optimal growing conditions, estimates of crop growth may be inaccurate. Crop monitoring...

Our understanding of the effects of landscape structure on ecosystem services (ES) remains at a very early stage, despite a large body of literature on the effects of the composition and configuration of natural land cover on some ES. Here, I argue that a comprehensive understanding of the effects of landscape structure on ES requires us to reconsider what constitutes landscape structure for ES...
