Our paper will show data on quantity, typology, distribution of beach litter (Anthropogenic Marine Debris - AMD) within a coastal macroarea surrounding the Pelagos Sanctuary, an International ...Protected Area in the NW Mediterranean Sea. AMD Monitoring and characterisation have been performed by using SEACleaner Protocol: an adapted version of UNEP/IOC, OSPAR and EU guidelines. 11 beaches located in 5 different areas, have been monitored with a total amount of thirty three surveys, from January 2014 to December 2015, during different seasons. Three kinds of beaches have been considered: Natural (belonging to MPAs), Urbanized and Urban. A total of 34,027 items on a total area of 32,154 m2 have been removed and classified. Spatial difference in abundance and composition of AMDs - as well as beach environmental quality - has been detected. Natural sites, and particularly protected areas close to river mouths show a major density compared to other areas.
•MPAs close to important river mouths show major abundance of beached AMD.•Plastic is the most present material in all Sites surrounding the Pelagos Sanctuary.•All monitored beaches are polluted despite the degree of protection or cleaning activities.
The development of eco-sanctuaries has been an important response to the biodiversity crisis in New Zealand. They combine intensive predator control and biodiversity conservation, with a particular ...focus on endangered endemic wildlife within the local ecosystems. Tourism has been harnessed to fund conservation efforts, raising important questions about the experiences of visitors to eco-sanctuaries. This paper explores international visitors' perceptions and experiences of ecological restoration at New Zealand eco-sanctuaries. Theoretically framed by the field of environmental philosophy, we present an analysis of semi-structured interviews conducted with international visitors to eco-sanctuaries. Our findings identified competing interests among humans, endemic wildlife, invasive animals and the wider biological community tied to visitor perceptions of ecological restoration. These perceptions are largely found to be shaped by the interplay between environmental ethics and relevant awareness/knowledge of international visitors. The research contributes to emerging trans-disciplinary discourses that address tourism and environmental philosophy by offering an environmental ethics-awareness/knowledge framework to elucidate different visitor mindsets, with implications drawn for their distinct and nuanced experiences at the eco-sanctuaries. It also sheds light on the demand side of nature-based tourism by interrogating the perceived intrinsic value of the natural world and the potential of aesthetic value in conservation management.
Decades of overexploitation have devastated shark populations, leaving considerable doubt as to their ecological status
. Yet much of what is known about sharks has been inferred from catch records ...in industrial fisheries, whereas far less information is available about sharks that live in coastal habitats
. Here we address this knowledge gap using data from more than 15,000 standardized baited remote underwater video stations that were deployed on 371 reefs in 58 nations to estimate the conservation status of reef sharks globally. Our results reveal the profound impact that fishing has had on reef shark populations: we observed no sharks on almost 20% of the surveyed reefs. Reef sharks were almost completely absent from reefs in several nations, and shark depletion was strongly related to socio-economic conditions such as the size and proximity of the nearest market, poor governance and the density of the human population. However, opportunities for the conservation of reef sharks remain: shark sanctuaries, closed areas, catch limits and an absence of gillnets and longlines were associated with a substantially higher relative abundance of reef sharks. These results reveal several policy pathways for the restoration and management of reef shark populations, from direct top-down management of fishing to indirect improvement of governance conditions. Reef shark populations will only have a high chance of recovery by engaging key socio-economic aspects of tropical fisheries.
Marine debris (MD) is a serious environmental concern globally. Yet, few studies have reported on MD in sanctuary zones of the Indian Ocean. Consequently, coastal transects were conducted to ...determine MD quantity, composition and distribution at northern Ningaloo Marine Park, Western Australia. Debris density ranged between 0.004 and 0.02 items m−2 with the greatest density near Exmouth township. Composition was predominantly plastic (61%) with fishing-related items (25.5%) and plastic fragments/remnants (16%) the most numerous overall. Land-based and general sourced MD accounted for 88% of all debris. Debris levels were significantly lower at sites with higher visitation and increased distance from access points. There was no significant difference between sanctuary and non-sanctuary zones. Although not immune to MD, this study suggests its remote location, environmental awareness and management strategies implemented at Ningaloo Marine Park may be key to its low MD levels.
•Low marine debris levels were observed at the northern Ningaloo Marine Park (0.004–0.02 items m−2) composed of 61% plastic.•Land-based and general sources accounted for almost 90% of marine debris.•Lower debris levels with increased visitation and distance from access points suggestive of environmental stewardship.•Debris levels were not significantly different inside and outside of sanctuary zones.•Future management opportunities exist to further reduce marine debris, predominantly through education initiatives.
Understanding the economic value of marine sanctuaries such as the Florida Keys National Marine Sanctuary (FKNMS) is important to justify public and private investments and to provide information to ...support management activities and understand their role in the nation’s blue economy. Very few studies have employed economic contribution analysis in examining economic value, even though it is more useful in influencing the behaviors of decision makers. This study therefore employs such a methodology to determine the economic importance of tourism and visitor spending in the sanctuary to Monroe County, Florida’s economy. Visitors who came to the area for ocean recreation and tourism spent a total of USD 1.7 billion, which translates to a contribution of 19,688 total jobs, USD 752 million in total labor income, USD 1.2 billion in total value added, and USD 2 billion in total output to the region. With regard to the spending of snorkelers and divers only, total spending is about USD 1.07 billion, contributing about 12,441 total jobs, USD 466 million in total labor income, USD 767 million in total value added, and USD 1.2 billion in total output. Ocean recreation is therefore an important economic driver in the region and efforts should be directed at protecting the diverse and sensitive ecosystem of the sanctuary.
Zika virus (ZIKV) is associated with severe neuropathology in neonates as well as Guillain-Barré syndrome and other neurologic disorders in adults. Prolonged viral shedding has been reported in ...semen, suggesting the presence of anatomic viral reservoirs. Here we show that ZIKV can persist in cerebrospinal fluid (CSF) and lymph nodes (LN) of infected rhesus monkeys for weeks after virus has been cleared from peripheral blood, urine, and mucosal secretions. ZIKV-specific neutralizing antibodies correlated with rapid clearance of virus in peripheral blood but remained undetectable in CSF for the duration of the study. Viral persistence in both CSF and LN correlated with upregulation of mechanistic target of rapamycin (mTOR), proinflammatory, and anti-apoptotic signaling pathways, as well as downregulation of extracellular matrix signaling pathways. These data raise the possibility that persistent or occult neurologic and lymphoid disease may occur following clearance of peripheral virus in ZIKV-infected individuals.

•ZIKV can persist in cerebrospinal fluid and lymph nodes of infected rhesus monkeys•ZIKV persistence correlates with modulation of specific transcriptomic pathways•ZIKV anatomic sanctuaries may contribute to viral pathogenesis
Persistence of Zika virus in the CNS and lymphoid tissues of NHPs suggests that ZIKV infection may have consequences to humans beyond the reported birth defects.
Providing demonstrable and quantifiable evidence to substantiate the value of Marine Protected Areas like National Marine Sanctuaries is important for understanding their role in the blue economy, as ...well as gaining management and financial support for their protection. This study employs economic contribution analysis to estimate the economic contributions of ocean recreation spending of visitors to Gray’s Reef National Marine Sanctuary (GRNMS) and the coastal Georgia region. Employing economic contribution analysis is found to be more useful in influencing stakeholder decisions, and can therefore be a useful tool in providing inputs for management decisions related to marine protected areas. This study shows that visitors to coastal Georgia spent about USD 1.4 billion on ocean recreation activities in a single year. This translates to a total economic contribution of 18,950 jobs, USD 603 million labor income, USD 938 million value added, and USD 1.8 billion output. About USD 123 million of the total visitor spending can be attributed to GRNMS, contributing 1702 total jobs, USD 54 million in total labor income, USD 84 million in total value added, and USD 159 million in total output. This study highlights the importance of coastal Georgia and GRNMS as economic drivers of the region’s economy, supporting the need for continued management and investment in the Sanctuary and its resources.
The article assesses a model predicting outcome in counterinsurgencies based on the counterinsurgent's exposure to external friction and strategy. Unfavorable opinions, as well as insurgents' access ...to third-party support and sanctuaries, constitute sources of external friction. Strategies were categorized as mainly kinetic or population-centric. The model predicts: (1) counterinsurgents lose in contexts with high external friction regardless of strategy; (2) counterinsurgents applying a population-centric strategy win if external friction is low; (3) counterinsurgents applying a purely kinetic strategy win if external friction is low only by obtaining distinct tactical superiority. The model correctly predicted 27 of 30 examined cases.
The study of the two main extra-urban sanctuaries of Argos, the Heraion and the sanctuary of Zeus at Nemea, allows us to drawn a territorial history of the city during the Hellenistic and Imperial ...periods. While during the Classical and early Hellenistic periods, the Argives integrated extra-urban and border areas into their political and cultic system and into the representations they made of their city, there was a change of territorial paradigm under the domination of Hellenistic tyrants. These rulers privilege the centralization of the political, diplomatic and cultic functions within the walls of Argos, to the detriment of the extra-urban spaces condemned to become peripheries, which keep only economic or symbolic functions. Under the Roman domination, the community reappropriates part of these peripheral spaces and invests them with new functions, notably linked to the imperial cult.
Understanding seabird habitat preferences is critical to future wildlife conservation and threat mitigation in California. The objective of this study was to investigate drivers of seabird habitat ...selection within the Gulf of the Farallones and Cordell Bank National Marine Sanctuaries to identify areas for targeted conservation planning. We used seabird abundance data collected by the Applied California Current Ecosystem Studies Program (ACCESS) from 2004-2011. We used zero-inflated negative binomial regression to model species abundance and distribution as a function of near surface ocean water properties, distances to geographic features and oceanographic climate indices to identify patterns in foraging habitat selection. We evaluated seasonal, inter-annual and species-specific variability of at-sea distributions for the five most abundant seabirds nesting on the Farallon Islands: western gull (Larus occidentalis), common murre (Uria aalge), Cassin's auklet (Ptychorampus aleuticus), rhinoceros auklet (Cerorhinca monocerata) and Brandt's cormorant (Phalacrocorax penicillatus). The waters in the vicinity of Cordell Bank and the continental shelf east of the Farallon Islands emerged as persistent and highly selected foraging areas across all species. Further, we conducted a spatial prioritization exercise to optimize seabird conservation areas with and without considering impacts of current human activities. We explored three conservation scenarios where 10, 30 and 50 percent of highly selected, species-specific foraging areas would be conserved. We compared and contrasted results in relation to existing marine protected areas (MPAs) and the future alternative energy footprint identified by the California Ocean Uses Atlas. Our results show that the majority of highly selected seabird habitat lies outside of state MPAs where threats from shipping, oil spills, and offshore energy development remain. This analysis accentuates the need for innovative marine spatial planning efforts and provides a foundation on which to build more comprehensive zoning and management in California's National Marine Sanctuaries.
