Although most plants have flowers with both male and female sex organs, there are several thousands of plant species where male or female flowers form on different individuals. Surprisingly, the presence of well-established sex chromosomes in these dioecious plants is rare. The best-described example is white campion, for which large sex chromosomes have been identified and mapped partially. A ...

• United Nations Convention on the Law of the Sea (UN, 1982 (known as UNCLOS)), which includes a call for a maximum sustainable yield (MSY) approach to managing fisheries; • United Nations Conference on Environment and Development (UN, 1992a (known as UNCED)), including Chapter 17 of Agenda 21 which highlights a precautionary approach; • United Nations Straddling Fish Stocks Agreement of 1995 (...

This paper investigates the ecological-economic sustainability of coral reef socio-ecological systems under fishing and environmental pressures. To achieve this, a dynamic, spatially explicit, multi-species, multi-fleet fisheries model is developed. Stochastic shocks are assumed to alter cover consequently entire social-ecological system. The calibrated using ecological, socio-economic data in ...

The feasibilty of using Kalman Filter methods as the basis for an Aboriginal Whaling Management Procedure is explored in this paper. Adaptive Filters are used to obtain estimates stock size and posterior probability distributions MSY rate (MSYR) pre-exploitation K. A set catch control laws then on these size, which together with various combinations MSYR K, gives a cumulative distribution funct...

Anchovies (Stolephorus sp), need to be managed well because although as a natural resource that is open access if not properly, the management of fishery resources optimal and sustainable. One approach in fish with surplus production model. The analysis was conducted obtain best model aims know maximum sustainable catch (MSY), utilization rate, use anchovies. Data on catches anchovies fishing e...

Sherry Larkin, Department of Agriculture and Resource Economics, OSU. j1 \I specifications on recommended yields and social benefits, a 3-year bioeconomic model is employed. This management-level, optimal control model integrates population dynamics, intrinsic product quality (via proximate analysis) and industry economics to develop optimal intraand interseason harvest patterns (i.e., short-te...

The serious overfishing of most Mediterranean stocks demands urgent reforms of the management measures aiming to guarantee the sustainability of resources, notably when compared with the improvement observed in other European areas. The new EU Common Fisheries Policy (CFP) constitutes an excellent opportunity to introduce the changes needed for such a reform. According to this CFP, all European...
