A record of a red-footed Booby Sula Sula (L.) from the Cape Verde Islands, with a review of the status of this species in the South Atlantic Ocean Naturalis
Hartog, J.C. den.
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...

Contracting with Agents Seeking Status AgEcon
Bontems, Philippe.
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...

The distribution and diversity of whales and dolphins (Cetacea) in the southern North Sea: 1970-2005 Naturalis
Meij, S.E.T. van der; Camphuysen, C.J..
Between 1970 and 2005 sightings data of cetaceans in the southern North Sea were collected as part of the Marine Mammal Database of the Dutch Seabird Group. The data include incidental sightings and reports as well as results from systematic surveys and seawatching data. They are therefore difficult to correct for fluctuations in observer effort. The material was evaluated firstly to see which species occur in Dutch waters and, secondly, to see if any spatial and temporal trends in abundance can be observed. In this study the harbour porpoise (Phocoena phocoena) is excluded from the analysis, except in the discussion, where the results are put into context with data about strandings and overall abundance. The status of the 17 different species that have...

The Micronesian megapode Megapodius laperouse: conservation and research needs Naturalis
Stinson, D.W.; Glass, P.O..
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...

สถานภาพการผลิตน้อยหน่าและน้อยหน่าลูกผสมในอำเภอปากช่อง จังหวัดนครราชสีมา Thai Agricultural
Ruangsak Komkhuntod; Kawit Wanichkul.
Primary data were collected by interviewing 80 farmers in Pakchong District, Nakhon Ratchasima Province (during January to September 2006) in order to describe the status of sugar apple and Annona hybrid production. It was found that most of the farmers were male 41-50 years old, married and had primary education. Their major occupation was orchard growing with 11-15 years of experience. Only one or two family members could work in the orchard. The labors were family member and employee. The average of growing area was 23 rai. The land characteristics was plateau and plain with sandy loam soil and tropical climate weather. The fruit trees were grown by seedling and grafting respectively. Soil preparation was done two time to break up the soil before...
