The sustainable management of small-scale fisheries in coral reef ecosystems constitutes a difficult objective especially because these fisheries usually face several stringent pressures including demographic growth and climate changes. The implications are crucial in term of food security as fish represents the major protein source for local populations in those...
The sustainable management of small-scale fisheries
in coral reef ecosystems constitutes a difficult objective
especially because these fisheries usually face several stringent pressures including demographic growth and climate
changes. The implications are crucial in term of food security as fish represents the major protein source for local

Most of the kinetic energy of ocean circulation is contained in ubiquitous
mesoscale eddies. Their prominent signatures in sea surface height have rendered satellite
altimetry highly effective in observing global ocean eddies. Our knowledge of ocean eddy
dynamics has grown by leaps and bounds since the advent of satellite altimetry...
Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...
Using gravity, magnetic, bathymetric and seismic
refraction data, I have constructed a geophysical cross-section
of the central part of the northern Gulf of California. The
section exhibits a crustal thickness of 18 km and features an
anomalous block of high density lower basement (3.15 g/cm³)
which probably resulted from rifting...
The compressive behavior of continuous fiber composites is not as well
understood as their tensile behavior because research and industrial applications have until
recently focused on the latter. Furthermore, most theoretical and experimental studies on
the compression of composites have examined the case of unidirectional specimens with
fibers along the...
Balancing selection is one of the mechanisms which has been proposed to explain the maintenance of genetic diversity in species across generations. For species with large populations and complex life histories, however, heterogeneous selection pressures may create a scenario in which the net effects of selection are balanced across developmental...
In this paper the emphasis is put on an important aspect of renewable resource use that was disregarded until now. It is the evolution of environmental carrying capacity which is traditionally interpreted as a maximal population level that can be supported by the environment (or by habitats of which it...
