If the study of the fisheries dynamics increasingly seeks to take into
account the evolution of fishing fleets, the main mechanisms which govern
their evolution at the local, national or international levels, are often not
studied at all, or only partially studied. This applies in particular to vessel
entry and...
Establishing marine protected areas (MPAs) often results in fishers being
displaced from at least some of their existing grounds. A direct
consequence of this is that governments may be required to make
compensatory payments to the firms that are affected. Experience has
demonstrated that these payments can be significant, as...
In the quest to limit the bycatch of non-target species, marine protected
areas (MPAs) have been frequently utilized. MPAs are popular with
ecologists and fishery managers because of their relative ease of
administration, habitat protection benefits, and the widespread acceptance
of MPAs as an instrument of choice for the ecosystem...

Recreational fisheries are severely understudied by fisheries economists, in
spite of their growing importance in the context of fisheries management.
While recreational demand models have been extensively applied to
recreational fisheries, they have rarely been successfully integrated with
bioeconomic models to evaluate policy changes. Furthermore, theoretical
models of open access...
The Bolivian government is using a portion of the rent generated from its fossil fuel reserves to fund unconditional cash transfers as a means of redistributing resources. Although some countries have enacted conditional cash transfers in the past, these unconditional transfers are unique since they only have been implemented in...
Understanding the complexities of ecosystems is difficult enough, but when the human dimension is added to the inherent uncertainty and risk in fisheries management, the actual versus expected results move from the counter-intuitive to the paradoxical. Without an adequate understanding of the interrelationships between ecosystem components, including the human dimension,...
Intraexciton transitions in semiconductor quantum wells are modulated by strong and tunable few-cycle terahertz pulses. Time-resolved terahertz-pump and optical-probe measurements demonstrate that the 1s heavy-hole and light-hole exciton resonances undergo large-amplitude spectral modulations when the terahertz radiation is tuned near the 1s–2p intraexciton transition. The strong nonlinear optical transients exhibit...

Turbulent mixing of salt is examined in a shallow salt wedge estuary with strong fluvial and tidal forcing. A numerical model of the Merrimack River estuary is used to quantify turbulent stress, shear production, and buoyancy flux. Little mixing occurs during flood tides despite strong velocities because bottom boundary layer...
Instability and turbulence in sheared, salt-fingering favorable stratification are studied
using three-dimensional direct numerical simulations (DNS). Salt-fingering favorable
stratification is gravitationally stable, because the unstable vertical gradient of salinity
is stabilized by temperature (warm, salty over cool, fresh water-masses). Salt-fingering
instability can occur at the interface of these different water-masses....
The objective of this research is twofold. First, this study uses a
cointegration model to investigate possible potential long-run pricing

For OR 91G x PI433251B, analyses produced nine linkage groups corresponding to...
Questions: Are traits related to the performance of plant species in restoration? Are the relationships between traits and performance consistent across the functional groups of annual forbs, perennial forbs, and grasses? Do the relationships between traits and performance depend on neighboring functional groups? Location: A former agricultural field, being restored...
In the globalizing era, world trade of fishery resources has sharply
increased. Because capture fisheries are hard to be managed, growing
opportunity for fishery trade may cause the overexploitation of world
fishery resources. For instance, the theoretical model developed by
Takarada et al (2009, mimeograph) implies that fish stocks may...
Metals are a persistent form of freshwater pollution and have been shown to bioaccumulate in aquatic macroinvertebrates through direct contact with contaminated water, sediments, and through consumption of contaminated organisms. This research explored the longitudinal bioaccumulation patterns of 5 common trace metals (Cr, Cu, Zn, Cd, and Pb) in the...
The paper argues that Cost-Effectiveness Analysis (CEA) can be a suitable
evaluation tool in cases where some of the benefits are difficult to measure
(e.g. habitat protection) and where the tangible benefits are lower than the
cost. An example is polities aiming at protecting a single species in
multispecies fisheries....
Considerable attention has been applied to the development of models explaining how fish stocks change over space
and time, from relatively simple stock-recruitment relationships to ecosystem models with a complex food web
structure. However, in many case studies fishing effort is assumed to be exogenous and even in dynamic models...
A major simplification in bioeconomic models is that the model parameters
and functional forms are assumed known. In fisheries, the failure to capture
model uncertainty can easily cause overconfidence in model outputs and
resultant policy recommendations. Although fisheries modelers regularly
assume rather complete knowledge of the systems they study, in...
This paper illustrates a case study to identify problems and actions to build the basis for an integrated fishery management plan, considering stakeholders participation. The application was made on the southern complex multispecies groundfish fishery, where operate various scales of production under a right-based fishing system. A multimethological approach (Mingers,...
In developing countries the framework for institutional engagement in small-scale fishing communities needs to consider the regional, social, economic and environmental complexities of informal resource-based economies. The combination of socio-economic trajectory of artisanal fisherfolks, their relationship with the environment, the economic pressures and the public policy framework, which often regarded...
Massive die-offs of Bufo bufo gargarizans were observed in May 2008 in Mangwal
Gee, Korea. To find out the causes for this disaster several different elements
were examined: pH, total nitrogen, dissolved oxygen (DO), and dissolved heavy
metal, suspension, introduced species, habitat change, disease, temperature
changes, and precipitation and humidity....
Fisheries economics theory suggests that weak fishery management
institutions, such as an open access regime, provide the motivation for
fishers to act as if they have infinite discount rates. This theory has serious
implications for the management of small-scale reef based fisheries in
developing countries, many of which are open...
Tide-topography coupling is important for understanding surface-tide energy loss, the intermittency of internal tides, and the cascade of internal-tide energy from large to small scales. Although tide-topography coupling has been observed and modeled for 50 years, the identification of surface and internal tides over arbitrary topography has not been standardized....
