| The first Western Palearctic record of a Red-footed Booby Sula sula (L., 1766), a brown whitetailed morph observed on Cima (Cape Verde Islands), is described. The status of this species in the tropical South Atlantic Ocean is evaluated. At present, Fernando de Noronha is the only South Atlantic stronghold of the species (ca. 4000 individuals; cf. Oren, 1984). The species has disappeared, or almost so, from other islands (St. Helena: absent; Ascension:0-30 individuals; Ilha da Trindade: less than 100 pairs). A link may exist between the apparent recent increase of the population of Fernando de Noronha and the apparent recent decline of the Trindade population. It seems possible that the Trindade population for some unknown reason has migrated to Fernando de... |

| We explore in this paper the consequences of status seeking preferences among agents contracting with a private principal in the context of production. We examine in particular the case of envy and we show that in general envy entails augmented distortions due to asymmetric information in optimal contracts. Furthermore if the principal neglects the preferences of the agents with respect to status, then potentially there is under-participation to the contract. We also show that if the principal is free to choose who can participate to the contract, then under some conditions the principal may prefer to contract with only a subset of potentially "profitable" agents (that is where his utility is strictly positive). We then ask whether contracting with agents... |

| Introduction The Micronesian megapode Megapodius laperouse, one of the smallest megapode species, is endemic to the Mariana (M. l. laperouse) and Palau (M. l. senex) Islands in the western Pacific. We outline here the outlook for the species and aspects of their biology that need investigation. A more detailed account of the status and biology of M. l. laperouse in the Marianas is in preparation. Status and distribution The Micronesian megapode in the Marianas is now restricted to the remote volcanic islands north of Saipan, with the exception of a small remnant population on Aguijan and a reintroduced population on Saipan. In historic times, this species was found on the larger coral islands of Guam, Rota, Tinian, and Saipan, but was common only on... |
