Viable coalitions in open access

Creator:: Doyen, Luc and Pereau, Jean-Christophe
Abstract:: This article gives insights on the complex balance between coalitions structure, resource state or dynamics and agents’ heterogeneity to avoid bio-economic collapses. A model bringing together coalition games and a viability approach is proposed to focus on the compatibility between bio-economic constraints and an exploited common stock dynamics. It is...

The triple bottom line: Meeting ecological, economic and social goals with Individual Transferable Quotas

Creator:: Doyen, Luc, Little, L. Rich, Pereau, Jean-Christophe, and Thébaud, Olivier
Abstract:: This paper deals with the sustainable management of a renewable resource based on individual and transferable quotas (ITQs) when agents differ in terms of harvesting costs or catchability. In a dynamic bio-economic model, we determine the conditions under which the manager of an ITQ system can achieve sustainability objectives which...

A Bio-Economic Model for the Viable Managementof the Coastal Fishery in French Guyana

Creator:: Cisse, Abdoul, Gourguet, Sophie, Doyen, Luc, Pereau, Jean Christophe, Blanchard, Fabian, and Guyader, Olivier
Abstract:: The coastal fishery in French Guyana is a challenging case study for the implementation of the ecosystem based fishery management. Although the current situation of this small scale fishery could be considered as satisfactory, the viability of the fishery can be questioned. Indeed according to demographic scenarios, the growth of...

Structure and hydraulic function of xylem in two tree species with contrasting amounts of sapwood, Pseudotsuga menziesii and Pinus ponderosa

Creator:: Domec, Jean-Christophe
Abstract:: Every wood anatomist knows that the wood near the center of a tree (juvenile wood) differs from the wood laid down at some distance from the pith (mature wood), and that the wood produced during the spring (earlywood) differs from the wood produced during the summer (latewood). There is a...

A Model of Fishing Through Fish Communities

Creator:: Thébaud, Olivier and Soulie, Jean-Christophe
Abstract:: Recent work in the domain of fisheries ecology has shown that major changes occur in fish communities exploited by commercial fisheries. Selective fishing pressure on the more highly valued components of fish communities is amongst the key factors proposed to explain these changes. Under de facto open access conditions, it...

Safety factors for xylem failure by implosion and air-seeding within roots, trunks and branches of young and old conifer trees

Creator:: Domec, Jean-Christophe, Warren, Jeffrey M., Meinzer, Frederick C., and Lachenbruch, Barbara
Abstract:: The cohesion-tension theory of water transport states that hydrogen bonds hold water molecules together and that they are pulled through the xylem under tension. This tension could cause transport failure in at least two ways: collapse of the conduit walls (implosion), or rupture of the water column through air-seeding. The...

Bordered pit structure and function determine spatial patterns of air-seeding thresholds in xylem of Doulglas-fir (Pseudotsuga menziesii; Pinaceae) trees

Creator:: Domec, Jean-Christophe, Lachenbruch, Barbara, and Meinzer, Frederick C.
Abstract:: The air‐seeding hypothesis predicts that xylem embolism resistance is linked directly to bordered pit functioning. We tested this prediction in trunks, roots, and branches at different vertical and radial locations in young and old trees of Pseudotsuga menziesii. Dimensions of bordered pits were measured from light and scanning electron micrographs,...

Transpiration-induced axial and radial tension gradients in trunks of Douglas-fir trees

Creator:: Domec, Jean-Christophe, Meinzer, Frederick C., Gartner, Barbara L., and Woodruff, D.
Abstract:: We determined the axial and radial xylem tension gradients in trunks of young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees. Axial specific conductivity (ks-a) and sap flux density (Js) were measured at four consecutive depths within the sapwood at a stem height of 1 m. By definition, at a given position...

Dynamic variation in sapwood specific conductivity in six wood species

Creator:: Domec, Jean-Christophe, Meinzer, Frederick C., Lachenbruch, Barbara, and Housset, Johann
Abstract:: Our goals were to quantify how non-embolism-inducing pressure gradients influence trunk sapwood specific conductivity (ks) and to compare the impacts of constant and varying pressure gradients on ks with KCl and H2O as the perfusion solutions. We studied six woody species (three conifers and three angiosperms) which varied in pit...

Wood density and hydraulic properties of ponderosa pine from the Willamette Valley vs. the Cascade Mountains

Creator:: Bouffier, Laurent A., Gartner, Barbara L., and Domec, Jean-Christophe
Abstract:: The Willamette Valley (WV) race of ponderosa pine (Pinus ponderosa) is being widely planted for timber in the Willamette Valley, western Oregon, because it grows in habitats that are either too wet or too dry for Douglas-fir (Pseudotsuga menziesii). Compared to the eastern Cascade Mountains (CM), the WV has 3...
