  • 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 ...

  • Biodiversity Detectives Solve Mysteries with Environmental DNA

    For years, Monterey Bay Aquarium’s 1.2 million gallon main tank has been a source of thrill for visitors seeking fish-eye views of life in the pounding Pacific Ocean right outside its doors. Now, thanks to advances in DNA sequencing, it’s also becoming a model for how to survey life inthat vast ocean with just a few glasses of water. In a study published last January in ...

  • Withdrawal of fresh water may reduce aquatic diversity

    Withdrawing fresh water from rivers and streams may adversely affect the health of fish and aquatic insects, according to a research team studying correlations between the two in North Carolina. The researchers, charged by the state of North Carolina and the state’s Department of Environmental Quality, investigated the relationship between changes in surface water flow and the diversity of ...

  • 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 ...

  • Overcoming water challenges through nature-based solutions

    Freshwater is a key resource and medium for various economic sectors and domestic purposes but its use is often at the expense of natural ecosystems. Water management must change to deal with urgent issues and protect aquatic ecosystems and their services, while addressing the demand for water from the competing claims for cities, agriculture, industry, energy and transport. In this paper key ...

  • Water quality monitoring in wetland ecosystems using microbial model communities

    This study reviews the concept of model communities for water quality assessment in aquatic ecosystems. The feeding habits of protozoans were used to unite species into functional, trophic groups. Colonising communities were dominated by bacterivorous Flagellate Species (Sf). A new Index of Periphyton Flagellates (IPF) as an indicator of the trophic status of a water-body was developed. ...

  • In search of effective bioassessment of urban stormwater pond sediments: enhancing the ‘sediment quality triad’ approach with oligochaete metrics

    Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. As receiving waters, they are under the influence of intermittent pollution from urban wet-weather discharges. Meanwhile they offer new aquatic habitats balancing the transformation of initial ecosystems and their associated biodiversity. Bioassessment of stormwater ...

  • Beta diversity as a tool for determining priority streams for management actions

    Beta diversity has become essential for understanding ecosystem functioning and for determining biodiversity-conservation priority areas. However, the beta diversity patterns of invertebrates in tropical aquatic ecosystems are not well known, particularly in streams. Using data from low-order streams located in southern Brazil, we evaluated the beta diversity of Chironomidae. We tested the ...

  • A brief review on pollution and ecotoxicologic effects on Sundarbans mangrove ecosystem in Bangladesh

    The natural ecosystem of the Sundarbans mangrove wetlands is under threat due to anthropogenic activities. This ecosystem has become vulnerable to pollution such as oil spillage, heavy metals, and agrochemicals – which may have changed the mangrove ecosystem's biogeochemistry. In this paper, the present status of Sundarbans' mangrove pollution is reviewed. The ecotoxicologic effect on its aquatic ...

  • Global Monthly Water Scarcity: Blue Water Footprints versus Blue Water Availability

    Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by ...

  • Species diversity of the Okavango Delta, Botswana

    Abstract.  In the Okavango Delta (about 28,000 km2) the number of identified species is 1,300 for plants, 71 for fish, 33 for amphibians, 64 for reptiles, 444 for birds, and 122 for mammals. The local occurrence of different species of these taxonomic groups in the Okavango Delta is mainly due to a hydrological gradient from permanent streams and swamps to seasonal floodplains, riparian ...

  • A fully automated system for measurements of photosynthetic oxygen exchange under immersed conditions: an example of its use in Laminaria digitata (Heterokontophyta: Phaeophyceae)

    Abstract A new, fully-automated, closed-chamber system was developed for measuring photosynthetic activity in aquatic plants, algae, or corals during immersion. The performance of this system, which monitors oxygen exchange, was evaluated both in the laboratory and in situ under natural conditions using the seaweed Laminaria dtgitata. Intact, large individuals were placed inside the chamber ...

  • Bringing aeroconservation down to Earth

    From migrating birds to pollinating bees to seed-dispersing plants, thousands of species depend on the quality of the aerosphere­ — the layer of air that surrounds our planet. Despite this, aircraft, wind farms, drones, telecommunication towers and other anthropogenic infrastructure increasingly crowd this critical habitat. Current species conservation efforts are generally focused on ...

  • Freshwater quality — SOER 2010 thematic assessment

    Water is critical for life and is integral to virtually all economic activities, including food and industrial production. Not only is clean water a prerequisite for human health and well-being, it provides for aquatic habitats that support healthy freshwater ecosystems. A range of pollutants including nutrients, biocides, pathogenic micro-organisms, industrial and household chemicals, metals and ...

  • Release of the 2006 IUCN Red List of Threatened Species reveals ongoing decline of the status of plants and animals

    The number of known threatened species reaches 16,119. The ranks of those facing extinction are joined by familiar species like the polar bear, hippopotamus and desert gazelles; together with ocean sharks, freshwater fish and Mediterranean flowers. Positive action has helped the white-tailed eagle and offers a glimmer of hope to Indian vultures. Geneva, Switzerland, 2 May 2006 (IUCN) – The ...

  • Towards climate-responsible peatlands management

    Peatlands are lands with a naturally accumulated peat layer at their surface. They are found all over the world and come in many forms, display many different characteristics and are used in many different ways. Even though peatlands extend over a relatively small portion of the earth’s land surface, they hold a large pool of carbon. There is no universal definition of peatlands. For the ...
