The presence of top predators can affect prey behaviour, morphology and life history, and thereby can produce indirect population consequences greater and further reaching than direct depredation would have alone. Raptor species in the Americas are recovering since restrictions on the use of dichlorodiphenyltrichloroethane (DDT) and the implementation of(More)
We report that a latitudinal cline in intertidal food distribution is associated with the nonbreeding distribution of the Western Sandpiper (Calidris mauri). This novel result is the first to demonstrate a clear relationship between patterns of differential nonbreeding distribution and food availability for any shorebird species. Within each age class and(More)
1. With the aid of a novel survivorship model, an 8-year field study of social and maternal factors affecting duckling survival in eiders (Somateria mollissima) revealed that duckling survival probability varies in accordance with maternal brood-rearing strategy. This variability in survival provides compelling evidence of different annual fitness(More)
Tree snails of the family Partulidae have declined on Guam since World War II. One species, indigenous to the western Pacific, Partu/a radio/ata, is still locally common along stream courses in southern areas of the island. The Mariana Island endemic Samoanajragilis is present but not found in abundance anywhere on Guam. Partu/a gibba, another Mariana(More)
We report on the survival of populations of Cassin’s Auklet (Ptychoramphus aleuticus) that breed on two oceanic colonies in British Columbia: Triangle Island, near the northern end of the California Current Ecosystem, and Frederick Island to the north in the Alaska Current Ecosystem. We captured and banded birds at both colonies from 1994 to 2000 and(More)
2. This scheme is outlined by Hoffman and Rosenkrantz in Chapter One of their 1994. Unlike Hoffman and Rosenkrantz, however, I am interested not in the scheme as such but in the reality which the scheme describes. The reality is indeed independent of the scheme: the discipline of paleontology, after all, describes the universe of mesoscopic objects as this(More)

The same spirit of a practical-minded interest for the epistemology and methodology of economic science motivates the present paper. I will argue that the nature of human choice jeopardises the mainstream approach to analysing human action, and then show that the difficulties of analysing choice can be overcome once it is recognised that a whole class of(More)
When national borders in the modern sense first began to be established in early modern Europe, non-contiguous and perforated nations were a commonplace. According to the conception of the shapes of nations that is currently preferred, however, nations must conform to the topological model of (approximate) circularity; their borders must guarantee(More)
This essay is a contribution to social ontology, drawing on the work of John Searle and of Hernando de Soto. At the center of the argument is the proposition advanced by de Soto in his Mystery of Capital to the effect that many of the entities which structure our contemporary social reality are entities which exist in virtue of the fact that there are(More)
