Patterns and determinants of mammal species occurrence in IndiaJournal of Applied Ecology - Tập 46 Số 6 - Trang 1189-1200 - 2009
Krithi K. Karanth, James D. Nichols, James E. Hines, K. Ullas Karanth, Norman L. Christensen
Summary 1. Many Indian mammals face range contraction and extinction, but assessments of their population status are hindered by the lack of reliable distribution data and range maps. 2. We estimated the current geographical ranges of 20 species of large mammals by applying occupancy models to data from...... hiện toàn bộ
Linking contaminant profiles to the diet and breeding location of American dippers using stable isotopesJournal of Applied Ecology - Tập 41 Số 3 - Trang 502-512 - 2004
Christy A. Morrissey, Leah I. Bendell‐Young, John E. Elliott
Summary
Individual variation in contaminant levels is a common occurrence in many toxicology studies, but the exact cause is often unclear. We investigated the influence of diet and breeding location on individual bird contaminant profiles using a colour‐marked population of American dippers ... hiện toàn bộ
A revised model for lipid‐normalizing δ13C values from aquatic organisms, with implications for isotope mixing modelsJournal of Applied Ecology - Tập 43 Số 6 - Trang 1213-1222 - 2006
Mikko Kiljunen, Jonathan Grey, Tuula Sinisalo, Chris Harrod, Hemmo Immonen, Roger I. Jones
Summary
Stable isotope analyses coupled with mixing models are being used increasingly to evaluate ecological management issues and questions. Such applications of stable isotope analyses often require simultaneous carbon and nitrogen analyses from the same sample. Correction of the carbon isotope value...... hiện toàn bộ
Effects of agricultural intensification on plant diversity in Mediterranean dryland cereal fieldsJournal of Applied Ecology - Tập 47 Số 4 - Trang 832-840 - 2010
Laura José‐María, Laura Armengot, José M. Blanco‐Moreno, Montserrat Bassa, F. Xavier Sans
Summary 1. Agricultural intensification, at field and landscape scales, has caused a decrease in weed richness and changes in species composition. In order to prevent this loss of diversity and develop efficient management regimes, it is important to understand how both aspects of intensification affect plant diversity and the way in which th...... hiện toàn bộ
