Life history theory predicts evolutionary trade-offs between investing in immune defense and other traits. We investigated whether reduced longevity was associated with increased investment in immunity in an avian brood parasite, the brown-headed cow

We apply decision theory in a structured decision-making framework to evaluate how control of raccoons (Procyon lotor), a native predator, can promote the conservation of a declining population of American Oystercatchers (Haematopus palliatus) on the

Knowing whether, and to what extent, populations are regulated by density-dependent factors is important both in its own right and when developing management strategies for wildlife species. However, available tests for density dependence are typical

Generalizations used to support hypotheses about the evolution of fidelity to breeding areas in birds include the tendency for fidelity to be greater in adult birds than in yearlings. In ducks, in contrast to most bird species, fidelity is thought to

The first large-scale, co-operative, studies of marked birds in North America were attempted in the 1950s. Operation Recovery, which linked numerous ringing stations along the east coast in a study of autumn migration of passerines, and the Preseason

This paper examines the performance of the Central Statistical Office's leading indicators for predicting turning points in the U.K. growth cycle. Three methods for extracting a signal are considered: a simple mechanical rule based upon the direction

We present a novel technique for the calibration of a high speed FBG interrogation system which incorporates an Arrayed Waveguide Grating (AWG). It uses temperature tuning to wavelength sweep the AWG to generate calibration data and to determine the

Gate units designed using a push-pull MOSFET output for single nanosecond ultra-fast electronic shuttering (or "gating") of image intensifiers or photomultipliers normally have to be tuned to fit the capacitance load of the detector being gated. Phot
