  • Optimal operation of a multi-reservoir system for environmental water demand of a river-connected lake

    Dongting Lake, a large river-connected lake in the Yangtze River watershed, plays important roles in flood control, drought mitigation, and biodiversity conservation. Its ecosystem has recently been severely affected by upstream water resource development such as reservoir operations. In this study, an optimization model is developed for the operation of a multi-reservoir system, including the ...

  • Is biodiversity the best medicine?

    Forget laughter: Biodiversity could be the best medicine, at least when it comes to keeping plants healthy. Scientists have long been intrigued by how the number of plant species in an area affects plants’ risk of getting slammed by disease. In general, viewpoints boil down to two competing theories. The first, known as amplification, contends that the more ...

  • Is qualitative and quantitative metabarcoding of dung fauna biodiversity feasible?

    In biodiversity assessments, especially of small‐bodied organisms for which taxonomic expertise is lacking, identification by genetic barcoding may be a cost‐effective and efficient alternative to traditional identification of species by morphology, ecology and behavior. Here we test the feasibility and accuracy of such an approach using dung insects of practical relevance in ecotoxicological ...

  • Biodiversity of cyanobacteria in Tunisian freshwater reservoirs: occurrence and potent toxicity – a review

    In spite of the great environmental and sanitary importance of cyanobacteria, their biodiversity is little known in Tunisia. In this work, a review was carried out, based on literature data, of potentially toxic cyanobacteria occurrence in Tunisia. Microcystis, one of the most widely distributed toxic bloom-forming cyanobacteria genera, was represented by Microcytis ...

  • EU 2010 biodiversity baseline — adapted to the MAES typology (2015)

    Why do we need to revise the EU 2010 biodiversity baseline report? Scientific and policy context for the revision This report presents a revised overview of the EEA's EU 2010 biodiversity baseline report. The revision is necessary because the typology of ecosystems used in the 2010 report has since been altered by a working group of biodiversity experts. ...

  • A field test of the effect of spiked ivermectin concentrations on the biodiversity of coprophagous dung insects in Switzerland

    Veterinary medical product residues can cause severe damage in the dung ecosystem. Depending on the manner of application and the time after treatment, the excreted concentration of a given pharmaceutical varies. The popular anthelmintic drug ivermectin (IVM) can be applied to livestock in several different ways and is faecally excreted over a period of days to months after application. In a ...

  • 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 ...

  • Smart SUDS: recognising the multiple-benefit potential of sustainable surface water management systems

    How can we make sustainable urban drainage systems (SUDS) smart? SUDS help us to manage surface water runoff from urban environments but they are capable of delivering much more. This paper looks beyond the water quantity and quality improvement functions of SUDS and investigates the multiple benefits that can be gained by implementing smart SUDS solutions. This work provides a new perspective, ...

  • Evaluating wider benefits of natural flood management strategies: an ecosystem-based adaptation perspective

    Climate change is projected to alter river flows and the magnitude/frequency characteristics of floods and droughts. Ecosystem-based adaptation highlights the interdependence of human and natural systems, and the potential to buffer the impacts of climate change by maintaining functioning ecosystems that continue to provide multiple societal benefits. Natural flood management (NFM), emphasising ...

  • Keep it Fresh or Salty - An introductory guide to financing wetland carbon programs and projects

    Wetlands have been the focus of conservation and restoration efforts for over a century. A diverse portfolio of financing sources has been used for supporting such activities including philanthropy, multi- and bilateral aid, in-country governmental funding, tourismrelated and other usage fees, as well as fees and levies associated with wetlands-centric extractive industries (e.g. peat ...

  • Can we have our cities and biodiversity, too?

    Smart development could mean big benefits for biodiversity and urban areas alike. We are entering the most extensive and rapid phase of urban growth ever experienced. Not only are urban populations expected to double in just a few decades, physical urban space is expected to increase at an even faster pace. Estimates suggest that by 2050 a land area the size of South ...

  • Managing natural capital at a NZ University: toward a comprehensive accountability model

    The objective of this paper was to use a modified Jones (1996) natural capital inventory model to construct a baseline inventory of species, as well as the number of individual specimens against which future increases and decreases in the fern inventory of NZ University can be measured. By comparing historical records to the fern inventory, the paper provides some preliminary views on the ...

  • Urban habitats as a refuge for biodiversity: A case study in Greece

    Cities located in biodiversity hotspots can provide valuable refuges for a wide range of plants, a recent study suggests. Of the 379 plant species and sub-species recorded in the city of Ioannina, Greece, 27 were of conservation interest. Town planners can ensure that cities play an important role in supporting regional biodiversity when designing future urban developments, the researchers say. ...
