Die letzte Chance, eine ökologische Katastrophe zu verhindern
28. April 2014 – Der NABU hat am 17. April nach Umweltschadensgesetz gegen den Bau des Offshore-Windparks Butendiek Klage beim Verwaltungsgericht Köln eingelegt. Grund für die Klage ist, dass der Umweltverband durch den Windpark Schäden bei streng geschützten Meeresvögeln und Schweinswalen befürchtet. (more…)
The Arctic is home to a growing number of whales and ships, and to populations of sub-Arctic whales that are expanding their territory into newly ice-free Arctic waters. (more…)
Wie sich Vielfalt im Tier- und Pflanzenreich entwickelt, ist bislang nur unzureichend verstanden. In den Binnengewässern unseres Planeten leben überproportional viele Tierarten, sechs von zehn dieser Tiere sind Insekten. Deshalb haben Wissenschaftler des LOEWE Biodiversität und Klima Forschungszentrums (BiK-F) nun gemeinsam mit Kollegen des Naturalis Biodiversity Center in Leiden und des Leibniz-Instituts für Gewässerökologie und Binnenfischerei (IGB) in Berlin das Potenzial von Süßwasserinsekten für die Erforschung der Biodiversität untersucht. Die Ergebnisse wurden jetzt in der diesjährigen Ausgabe des renommierten Fachjournals Annual Review of Entomology veröffentlicht.
Binnengewässer bedecken gerade einmal ein Prozent des Planeten, und doch leben in diesen Ökosystemen zehn Prozent aller Tierarten dieser Erde. Nach heutigem Kenntnisstand sind sechs von zehn dieser Tiere Insekten. Ein international zusammengesetztes Team mit Wissenschaftlern des LOEWE Biodiversität und Klima Forschungszentrums (BiK-F), des Biodiversity Center in Leiden und des Leibniz-Instituts für Gewässerökologie und Binnenfischerei (IGB) in Berlin untersuchte nun in einer Übersichtsstudie, inwieweit diese erstaunliche Vielfalt der Süßwasserinsekten dazu beitragen kann, die Entstehung von Artenvielfalt zu verstehen.

Max Li’s research could inform policies to promote sustainable native environments and curb the invasion of alien plant species.
Max Li, a University of Arizona doctoral student in the Department of Ecology and Evolutionary Biology, is studying mechanisms that determine how competing desert plants can coexist with each other and what factors can cause the destruction of this stable coexistence.
His research could help inform policies to curb the spread of invasive species. (more…)
Study Offers First Look at Green Sea Turtle Habitat Use in the Dry Tortugas
DRY TORTUGAS, Fla. – Nesting green sea turtles are benefiting from marine protected areas by using habitats found within their boundaries, according to a U.S. Geological Survey study that is the first to track the federally protected turtles in Dry Tortugas National Park.
Green turtles are listed as endangered in Florida and threatened throughout the rest of their range, and the habits of green sea turtles after their forays to nest on beaches in the Southeast U.S. have long remained a mystery. Until now, it was not clear whether the turtles made use of existing protected areas, and few details were available as to whether they were suited for supporting the green sea turtle’s survival.

TORONTO, ON – Ecologists at the University of Toronto and the Swiss Federal Institute of Technology Zurich (ETH Zurich) have found that, given time, invading exotic plants will likely eliminate native plants growing in the wild despite recent reports to the contrary.
A study published in Proceedings of the National Academy of Sciences (PNAS) reports that recent statements that invasive plants are not problematic are often based on incomplete information, with insufficient time having passed to observe the full effect of invasions on native biodiversity. (more…)
COLUMBIA, Mo. — While Americans prepare to cook millions of turkeys for Thanksgiving, a geothermal energy system developed by a University of Missouri engineer will be keeping live turkeys toasty during the chilly autumn weather. In a prototype facility, designed by a University of Missouri engineer, environmentally and economically friendly geothermal energy is keeping turkeys comfortable during both cold and hot weather. The system is designed to reduce utility costs while improving the air quality for the birds.
“This is our first prototype of a geothermal system in a commercial livestock operation,” said Yun-Sheng Xu, associate research professor in civil and environmental engineering. “Our first set of performance data suggests that farmers could cut their heating costs in half at current propane prices. Currently, two units are installed at the test farm. Other farmers could begin installing units on their turkey farms as soon as next year, for use by next winter.” (more…)
A new app which encourages people to say “good morning Mr Magpie” via their mobile phone will help scientists evaluate the benefits which birds bring to the quality of human life.
Whether you view them with sorrow or joy, using your smart device to help build up a national database of sightings of the distinctive black-and-white birds will feed into wider research by the University of Exeter to assess how much value people place on having birds in their gardens.
Dr Richard Inger, at the Environment and Sustainability Institute on the University’s Cornwall Campus, said: “We chose to study magpies because they’re one of the most common garden birds in the UK and are easily recognisable. Many people already acknowledge them for luck, and we’re asking them to go one small step further and log sightings on their mobile phones. Magpies are not everyone’s favourite birds, but by getting involved you can help us to gather crucial data which will help us establish how much time the birds spend in different habitats. (more…)
