Peatlands support millions of people around the world, store twice as much carbon as all forests worldwide, and are home to many threatened species of plants and animals. Peatland degradation has devastating economic and social consequences. Wetlands International promotes global and national land use practices and policies that counter peatland destruction and degradation, promote conservation incentives and support local communities.

Fungal biodiversity and mycotoxigenic fungi in cooling-tower water systems in Istanbul, Turkey
This is the first study to assess fungal diversity and mycotoxigenic fungi in open recirculating cooling-tower (CT) water systems (biofilm and water phase). The production capability of mycotoxin from fungal isolates was also examined. The mean fungal count in 21 different water and biofilm samples was determined as 234 CFU/100 mL and 4 CFU/cm2. A total of 32 species were identified by internal transcribed spacer (ITS) sequencing. The most common isolated fungi belonged to the genera Aspergillus and Penicillium,...
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 plant species there are at a site, the more hosts there will be, and so the more disease there will be as well. The other, known as dilution, suggests...
The number one thing each of us can do to protect biodiversity
Reducing our consumption of animal products can go a long way toward conserving endangered habitat around the world. Agriculture expansion is the leading driver of natural habitat loss worldwide. However, most of this growth is not to produce vegetables, fruits or grains to be eaten by people. Ecosystems are destroyed overwhelmingly to feed livestock. Livestock production uses roughly three-fourths of all agricultural land and 30 percent of the land surface of earth, making it the largest use of land by humankind....
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 assessments of veterinary pharmaceutical residues in the environment. We produced eight known mixtures that varied in...
Biodiversity of cyanobacteria in Tunisian freshwater reservoirs: occurrence and potent toxicity ...
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 wesenbergii, found only in Lebna water reservoir, and Microcytis aeruginosa recorded in different water bodies. The invasive potentially toxic...
