The protein palmitoylation cycle has been shown to be important for protein signaling and synaptic plasticity. Data from our lab showed a change in the palmitoylation status of certain proteins with age. A greater percentage of the NMDA receptor subunits GluN2A and GluN2B, along with Fyn and PSD95 proteins, were...
Ricci flow deforms the Riemannian metric proportionally to the curvature, such that the curvature evolves according to a heat diffusion process and eventually becomes constant everywhere. Ricci flow has demonstrated its great potential by solving various problems in many fields, which can be hardly handled by alternative methods so far....
Peroxiredoxins (Prxs) make up an ancient family of enzymes that are the predominant peroxidases for nearly all organisms and play essential roles in reducing hydrogen peroxide, organic hydroperoxides, and peroxynitrite. Even between distantly related organisms, the core protein fold and key catalytic residues related to its cysteine-based catalytic mechanism have...
We measured activity levels of cesium radioisotopes ¹³⁴Cs and ¹³⁷Cs in wild edible fungi, mineral soil, and surface litter of the west coast of North America from southern California to northern Vancouver Island after the Fukushima nuclear accident. All activity measurements were below governmental limits for human health. ¹³⁷Cs activity...
Automated sound broadcast systems have been used to address a variety of ecological questions, and show great potential as a management tool. Such systems need to be reliable because treatments are often applied in the absence of a human observer and system failure can cause methodological ambiguity. During the breeding...
All parasitoid apostome ciliates infecting krill in the northeastern Pacific are currently assigned to the genus Pseudocollinia. Each krill specimen is apparently infected by only 1 Pseudocollinia species. We describe Pseudocollinia similis sp. nov., discovered infecting the krill Thysanoessa spinifera off Oregon, USA. Its protomite-tomite stage resembles that of P....

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...
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...
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....
Indonesia, with a coastline of over 95,000 KM and brackish water area of 1.2 million hactares has very vast fisheries potential. In 2013, Indonesia exported seafood worth 4.16 billion US$. The major markets for Indonesian fisheries are USA, EU, Canada, Japan and China. Indonesian fisheries producers and processors take care...
Many experts have argued that the traditional management of commercial fish stocks as single-species is short-sighted, wasteful, and ineffective. Ecosystem-based fisheries management (EBFM) now is being promoted as a potential solution to the problem. While much attention has been directed recently at the potential benefits of implementing EBFM for commercial...
This study compares globally available integrated ecological-economic models with focus on use and implementation in scientific and advisory contexts. The Ecosystem based Approach to (Fisheries) Management (EAM) calls for an understanding and management of fisheries and other uses of the marine environment that explicitly take into account ecological, economic and...
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...
In this study we have considered the theoretical aspects of Global Value Chain and empirically validated the concepts by taking up a case study of Kerala in India. We have initiated this study with the hypothesis that, the evolving stringent food safety standards imposed by the export markets of developed...
Shrimp aquaculture is one of the fastest growing economic activities in the coastal areas of Bangladesh and earns substantial foreign exchange for the country. However, the environmental degradation is a major concern for the sustainable development of this industry. This paper studies the tradeoffs between the economic and environmental performance...
Analyzing the socioeconomic impacts of fisheries management requires a distinctive array of information that has so far been less developed than the biological data used in stock assessment. In the case of the European Common Fisheries Policy the project SOCIOEC studies the socioeconomic effects of the new European fisheries management...

Post-tsunami field surveys in the Minami-Soma exclusion zone in the Fukushima Prefecture were delayed for 15 months after the 2011 Tohoku tsunami. The area was subject to access restrictions until June 2012 due to high radiation levels caused by the meltdown at the Fukushima Dai-ichi Nuclear Power Plant. The distribution...
Smart meters are being installed in consumers’ homes as both Europe and the United States move to the smart grid of intelligent energy networks. Yet not all homeowners are willing recipients and some demand to “opt out”. When balancing consumer privacy and data protection rights with the important societal benefits...
In recent work, Andrews, Chan, and Kim extend a result of Garvan about even rank and crank moments of partitions to positive moments. In a similar fashion we extend a result of Mao about even rank moments of overpartitions. We investigate positive Dyson-rank, M₂-rank, first residual crank, and second residual...
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...
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...
Individual fishing quota (IFQ) systems are typically expected to increase the profitability of a fishery and improve sustainability by ensuring catches remain within quotas. They can also have important distributional and ecological implications that result from shifts in catch and effort between different gears, regions, and habitats. In multispecies fisheries...
This paper presents a new technique for shape and topology optimization of fluid channels using generative design synthesis methods. The proposed method uses the generative abilities of graph grammars with simulation and analysis power of conventional CFD methods. The graph grammar interpreter GraphSynth is used to carry out graph transformations,...
Australian Commonwealth fisheries have adopted maximum economic yield as a target reference point. A bioeconomic model has been developed for one key fishery - the Northern Prawn Fishery - and is used in the provision of management advice. The development and application of this model has highlighted some challenges for...
Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to marine fisheries. While ITQs can improve the economic efficiency of fisheries, in practice their application rarely has the expected effects. In this study we compare the output predicted by an individual based model of quota...
As part of the ecosystem approach to managing fisheries and other uses of marine ecosystems, there has been a growing call for the development of integrated assessment tools to support the provision of both tactical and strategic management advice. Of particular importance in this domain is the development of models...
Can government regulations and company concerns to reduce their reputational and business risk lead to an increase in traceability programs? Are the drivers of traceability attributed to concerns over seafood sustainability, food provenance, quality and safety, fraud, and IUU fishing? These questions suggest there is a change in incentives and...
Within Indonesia and across the region the requirement for traceability within the seafood supply chain is limited to meeting the basic standard of HACCP, namely that the individual fish be traceable back to the 1st supplier, for quality sampling purposes. No common template for traceability exists and hence companies follow...
