Underwater interpretative trail: guidance to improve education and decrease ecological damage

Studies of environmental education on trails in the sea and their impact are scarce, especially as regards the Brazilian coast. Herein is analysed an implemented model of an interpretative guided underwater trail (free diving), undertaken in the Anchieta Island's Park, southeast Brazil. The activity consisted of a preparatory lecture, followed by a 350 m trail along the rocky shore. The results ...

Marine Birds as Indicators of Arctic Marine Ecosystem Health: Linking the Northern Ecosystem Initiative to Long-Term Studies

Marine birds are sensitive indicators of the condition of marine ecosystems in the Arctic, partly because they feed at the top of the arctic food chain. The Northern Ecosystem Initiative (NEI) recently supported four separate studies that investigated aspects of Arctic marine bird science which simultaneously addressed goals of the NEI to better understand northern ecosystems and their response ...

Stocking up filtration equipment for marine expeditions

February is here, and for many research teams across the world, that means it’s time to set sail. Shoulder seasons are an important time to conduct marine research because many algal and microbe species are in bloom. Whether your research has you voyaging the open sea or cruising in coastal waters, Sterlitech is here to stock the ship with all your laboratory filtration needs. We are proud ...

Effects‐based marine ecological risk assessment at a polychlorinated biphenyl‐contaminated site in Saglek, Labrador, Canada

Although the presence and distribution of polychlorinated biphenyls (PCBs) in Arctic marine environments has been well documented, the implications for the health of biota are poorly understood. In the present study, multiple lines of evidence, including site‐specific effects data, were used to assess PCB‐related risks to marine biota at a contaminated military site in Saglek Bay, Labrador, ...

'Nested' participation in hierarchical societies? Lessons for social- ecological research and management

In the shift from community-based ecosystem management to co-management by the government and user groups, the participation of local resource users has remained important. In research, participatory approaches aim to enable local communities to contribute to sustainability knowledge. However, the outcomes of participatory practice have been particularly meagre in hierarchical contexts. The ...

Toxicity of ZnO nanoparticles to the copepod, Acartia tonsa, exposed through a phytoplankton diet

Zinc oxide (ZnO) nanoparticles (NPs) are being increasingly utilized in a variety of products and applications and are therefore commonly discharged into aquatic environments, increasing exposure and potentially impacting aquatic organisms. ZnO NPs can depress growth of some marine phytoplankton, and several examples of NP trophic transfer have been documented, although not within planktonic ...

Attitudes of Europeans towards the issue of biodiversity

The European Union (EU) is committed to the protection of 'biological diversity', i.e. the variability among living organisms from all sources including, inter alia, terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems1. The EU has been legislating on biodiversity since the ...

Politics of marine conservation area in Indonesia: from a centralised to a decentralised system

This paper aims to analyse the current situation resulting from the Marine Conservation Area (MCA) in Indonesia in terms of the legal framework, institutional conflicts and the response of the local people. A case study of the centralised and decentralised MCA in West Lombok is presented, and the process of establishing the MCA and its institutional performance are reviewed. The performance of a ...

Impact of global climate change on fish growth, digestion and physiological status: developing a hypothesis for cause and effect relationships

Global climate change is impacting and will continue to impact on marine and estuarine fish and fisheries. Data trends show climate change effects ranging from fish growth, digestion physiology and performance in marine and freshwater ecosystems. The present study was designed to develop a concept for a cause and effect understanding with respect to climate-induced temperature and salinity ...

Emulsifying and metal ion binding activity of a glycoprotein exopolymer produced by pseudoalteromonas sp. Strain TG12

In this study, we describe the isolation and characterization of a new exopolymer that exhibits high emulsifying activities against a range of oil substrates and demonstrates a differential capacity to desorb various mono-, di-, and trivalent metal species from marine sediment under nonionic and seawater ionic-strength conditions. This polymer, PE12, was produced by a new isolate, ...

Hydrogeology in North America: past and future

This paper is a retrospective on the evolution of hydrogeology in North America over the past two centuries, and a brief speculation of its future. The history of hydrogeology is marked by developments in many different fields such as groundwater hydrology, soil mechanics, soil science, economic geology, petroleum engineering, structural geology, geochemistry, geophysics, marine geology, and more ...

Assessment of marine ecosystem services indicators: Experiences and lessons learned from 14 European case studies

This paper shares the experiences, observations and discussions that occurred during the completing of an ecosystem services' (ES) indicator framework to be used at European Union and Member States' level. The experience base was drawn from three European research projects and 14 associated case study sites that include 13 transitional‐water bodies (specifically 8 coastal lagoons, 4 riverine ...

Dissolved Organic Nitrogen Measurement in Reclaimed Water

Dissolved organic nitrogen (DON) is an emerging concern for wastewater reclamation and reuse communities since DON may react with disinfectants to form carcinogenic nitrogenous disinfection byproducts (DBP) (e.g., haloacetonitriles, N-nitrosodimethylamine (NDMA)) and to affect the speciation of currently regulated DBP (trihalomethanes and haloacetic acids). Also, DON is present in proteins that ...

Communication of the European Commission to the Council and to the Parliament on a European Community Biodiversity Strategy

INTRODUCTION 1. Biological diversity (biodiversity) is essential to maintain life on earth and has important social, economic, scientific, educational, cultural, recreational and aesthetic values. In addition to its intrinsic value biodiversity determines our resilience to changing circumstances. Without adequate biodiversity, events such as climate change and pest infestations are more likely ...

Deep sea mining: exploration is inevitable

Despite concern over adverse impacts, deep marine mineral exploration is set to become a global industry, says geologist Chris Yeats. Global demand for metals continues to grow, fuelled largely by increasing populations and the industrialisation and urbanisation of China and India. To meet this demand, the international minerals industry has had to search new areas of the globe for additional ...

Terrestrial sequestration

Trees play a key role in the environment's natural landscape due to their ability to prevent erosion. The Spanish Government says it will plant 45 million trees over the next four years to counter desertification caused by global warming. The massive tree–planting scheme aims to reduce the amount of carbon dioxide (CO2) in the atmosphere, the cause of global warming. It estimates that in the long ...

Diagnosis of potential stressors adversely affecting benthic communities in New Bedford Harbor, MA (USA)

Diagnosing the causes of impaired ecosystems in the marine environment is critical for effective management action. When ecological impairment is based on toxicological or biological criteria (i.e. degraded benthic community composition or toxicity test results), managers are faced with the additional problem of diagnosing the cause of impairment before plans can be initiated to reduce the ...

Performance of passive samplers for monitoring estuarine water column concentrations: 1. Contaminants of concern

Contaminants enter marine and estuarine environments and pose a risk to human and ecological health. Recently, passive sampling devices have been utilized to estimate dissolved concentrations of COCs, such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). In the present study, the performance of three common passive samplers was evaluated for sampling PAHs and ...
