Studies of avian movement ecology afford essential insights regarding species' life histories, population dynamics, habitat and resource requirements, and other ecological relationships. While it is widely recognized that events in different stages of the annual cycle have important implications for processes in avian ecology, evolution, and conservation, challenges associated with...
Overcapacity situations appear regularly in the activity of marine natural resource exploitation. The measure of capacity utilisation and allocative efficiency for fishing vessels is an approach that can determine the details of that overcapacity. On the one hand, DEA (Data Envelopment Analysis) methodology can be used in the case of...
Access restrictions to traditionally-used resources, that are associated with the establishment of marine protected areas (MPA), often generate conflicts. Public participation in decision-making process has been widely recognised as a critical factor in legitimising conservation policy and enhancing its success. This paper discusses fishers involvement issues in the context of...
In the early 1990s, the crisis of the fishing industry resulted in both economic and human tragedies. Drawing conclusions from the crisis the fishing fleets experienced at that time, some groups of producers started to think of better enhancement of their production. Since then, they have tried to adapt their...
My dissertation focuses on the evolutionary forces that have shaped the chemical signaling system of plethodontid salamanders. Pheromones mediate two phases of plethodontid reproduction: mate attraction prior to courtship and female persuasion during courtship. Substrate-borne chemical signals are believed to play an important role in mate attraction for these animals....
Winegrape growing is extremely dependent upon site-specific variables. To better understand the effect of rootstock-scion interaction in a cool climate region, an experimental vineyard was planted in 1997 at the Oregon State University Woodhall III property in the southern Willamette Valley. The first experiment consists of Pinot noir (clone FPMS...
The French Norway lobster (Nephrops norvegicus) fishery situated in the Biscay Bay is composed by about 250 costal trawlers. These boats are registered in harbours located in South Brittany (Le Guilvinec, Lorient, Concarneau) and in the Vendée (Sables d'Olonnes, La Cotinière). The main particularity of the fishery is that lobsters...
The objective of the paper is to briefly present a comparative analysis of trends in the characteristics of
selected European fleets, observed over the last fifteen years, as an introduction to three empirical studies
of the behavioural determinants of these trends. The analysis presented aims at (i) describing changes
observed...
The French Norway lobster (Nephrops norvegicus) fishery is composed by almost 250 beam trawlers, mainly registered in nine different harbours disseminated from South Brittany to Oléron Island. Even if the main target is Norway Lobster, these fishermen also catch juvenile Hake, Sole and other commercial fishes. Both Norway Lobster and...
The decision to enter or exit a fishery can be expected to depend on the anticipated profitability of operating in
this fishery, as a function of observed vessel performances in previous years. For a vessel exiting a fishery,
there may be several reasons including decommissioning, selling or operating elsewhere. Entry...
