Shrimp is one of the largest traded commodities in the world and account for about 50 percent of total export of marine products (3.5 billion US $) from India in value term during 2012-13. The European Union (EU) is the second largest buyer of Indian marine products with a share...
‘Interactive governance’ is an emerging theory gaining traction in the field of fisheries social science but as yet largely unexplored in the field of Marine Protected Area (MPA) planning and management. According to ‘interactive governance theory’, MPAs are a form of ‘governing system’ established to manage the interaction between natural...
Open Educational Resources (OER) are increasingly used
in the higher education landscape as a solution for a variety of
copyright, publishing and cost-prohibiting issues. While OERs are
becoming more common, reports of usability tests that evaluate how
well learners can use them to accomplish their learning tasks have
lagged behind....
Inherent nanomaterial characteristics, composition, surface chemistry, and primary particle size, are known to impact particle stability, uptake, and toxicity. Nanocomposites challenge our ability to predict nanoparticle reactivity in biological systems if they are composed of materials with contrasting relative toxicities. We hypothesized that toxicity would be dominated by the nanoparticle...
To test the hypothesis that embryogenesis depends upon α-tocopherol (E) to protect embryo polyunsaturated fatty acids (PUFAs) from lipid peroxidation, new methodologies were applied to measure α-tocopherol and fatty acids in extracts from saponified zebrafish embryos. A solid phase extraction method was developed to separate the analyte classes, using a...
Water quality agencies and scientists are increasingly adopting standardized sampling methodologies because of the challenges associated with interpreting data derived from dissimilar protocols. Here, we compare 13 protocols for monitoring streams from different regions and countries around the globe. Despite the spatially diverse range of countries assessed, many aspects of...
The number of wildland–urban interface communities affected by wildfire is increasing, and both wildfire suppression and losses are costly. However, little is known about post-wildfire response by homeowners and communities after buildings are lost. Our goal was to characterise rebuilding and new development after wildfires across the conterminous United States....
LiDAR (Light Detection And Ranging) is an emerging remote-sensing tool that can provide fine-scale data describing vertical complexity of vegetation relevant to species that are responsive to forest structure. We used LiDAR data to estimate occupancy probability for the federally threatened marbled murrelet (Brachyramphus marmoratus) in the Oregon Coast Range...
Small-scale fisheries can generate significant profit, enhance resilience to shocks and crises, and make meaningful contributions to poverty alleviation and food security. There is very limited information on how well these potentials are being tapped in developing countries. This study examines the socioeconomic, livelihood and food security impacts of Ogun...
The fisheries sector is one of the world’s most globalized food producing sectors with almost 40 % of total production now entering international markets. Trade has a particular relevance and importance for developing countries who represent more than 50% of global fish exports thereby generating important benefits in terms of...
Transcription factors with multiple post-translational modifications (PTMs) are not uncommon, but comprehensive information on site-specific dynamics and interdependence is comparatively rare. Assessing dynamic changes in the extent of PTMs has the potential to link multiple sites both to each other and to biological effects observable on the same time scale....

Balancing the goals of economic development and sustaining ecosystem services remains a challenge for policymakers, particularly in the marine environment where ecosystem dynamics and human interactions are both complex and poorly understood. Implementing environmental management policies, such as environmental restoration, is a common response by policymakers where economic and environmental...
"An assessment of quota market efficiency: The New Zealand Annual Catch Entitlement (ACE) market
Balancing actual catch with Annual Catch Entitlement (ACE) is crucial to the efficient operation of the New Zealand Quota Management System (QMS). ACE market efficiency is dependent on the existence of ACE prices that reflect all...
Perhaps the most undervalued, yet critically important ecosystem services are related to socio-cultural values tied to the non-material benefits that arise from human-ecosystem relationships, such as bequest. Bequest values linked to natural ecosystems can be particularly significant for indigenous communities, whose livelihoods and cultures are often closely tied to ecological...
Amendment 80 of the Bering & Sea Aleutian Island Groundfish Fisheries Management Plan instituted groundfish retention standards (GRS) with the goal of reducing discards, which had been historically high for a particular fleet. The GRS continue to be a subject of regulatory attention as recent discard levels are markedly below...

As juvenile salmon migrate from freshwater into saltwater, physiological changes must occur to allow fish to osmoregulate in the marine environment. Juvenile spring Chinook salmon migrate to the ocean at different time periods, most notably in the fall (August – November; i.e. fall smolts) and spring (February – May; i.e....
Cross sections for radiative neutron capture have been determined for ⁹⁴Zr and ⁹⁶Zr using the activation technique with samples of naturally occurring Zr metal. The sensitivity to the correction for epithermal neutrons in the determination of small thermal cross sections is discussed, particularly in view of the variation in the...
This paper distinguishes three concepts of “race”: bio-genomic cluster/race, biological race, and social race. We map out realism, antirealism, and conventionalism about each of these, in three important historical episodes: Frank Livingstone and Theodosius Dobzhansky in 1962, A.W.F. Edwards’ 2003 response to Lewontin (1972), and contemporary discourse. Semantics is especially...
BACKGROUND: Large quantities of digital images are now generated for biological collections, including those developed in projects premised on the high-throughput screening of genome-phenome experiments. These images often carry annotations on taxonomy and observable features, such as anatomical structures and phenotype variations often recorded in response to the environmental factors...
Considerable expertise is required to grow high-quality hops, and brewers and hop growers alike have a common goal of obtaining the highest quality hops possible. Change in the chemical composition of hops during plant maturation is a dynamic process requiring a comprehensive chemical and sensory analysis in order to maximize...
For decades, the management of the Dutch flatfish fishery has included a variety of measures including individual transferable quotas (ITQ) and the implementation of a co-management system without succeeding in recovering the fishery to sustainable levels partly because of the multispecies aspect of the fishery with the two main commercial...
Since the 1990s Pacific island countries have been host to a plethora of projects to improve the management of coastal marine environments. Some of these have been about strengthening Indigenous and community-based forms of resource management. Some have been about building government capacity and strengthening legislative frameworks. Marine Protected Areas...
In 2009 the Fisheries Research and Development Corporation (FRDC) established the Social Sciences Research Coordination Program (SSRCP) to increase industry and government understanding and uses of social sciences in marine and fisheries management. Since that time a number of projects have been funded and promoted by the FRDC through the...
Since 2006, French quotas are shared out into annual catch entitlements per producer organizations (PO) according a stable allocation key. On this basis, PO’s have imposed catch shares to their own members but allocation and management rules are heterogeneous between PO’s. The objective of the paper is i) to assess...
In multi-species fisheries managed under ITQs, the existence of joint production may lead to complex catch-quota balancing issues. Previous modelling and experimental research suggest that, in such fisheries, some fishers may benefit from the ability to trade packages of fishing quotas, rather than fulfill their quota needs by simultaneously bidding...
