The University of Wisconsin-Madison's Monica Turner and her team describe what happens when Yellowstone -- adapted to recurring fires every 100 to 300 years -- instead burns twice in fewer than 30 years. Yellowstone as we know it faces an uncertain future, the researchers say, and one of the big questions they hope to answer is whether the forests can recover.
The susceptibility of ecosystems to disruption depends on a lot of factors that can't all be grasped. Ulrich Brose from University of Jena (Germany) has therefore developed a new method that provides good results with only a few information about the properties of predators. The model confirms that a large body mass index between predator and prey creates stable systems. It can also predict which predator species play a key role.
The caterpillars of Lymantria dispar or Gypsy Moth are voracious eaters capable of defoliating entire forests. Sometimes they can even make harm for coniferous forests. Gypsy Moths are widely spread in Europe, Asia and Northern America.
Historic climate change events can have a lasting impact on the genetic diversity of a species, reveals a new study on the alpine marmot.
Scientists have developed a new approach to describe the behaviors of microscopic marine larvae, which will improve future predictions of how they disperse and distribute.
Tropical forests are being deforested at an alarming rate to make way for agriculture; the good news is that they can regrow naturally when the fields are abandoned. An international research team including participation from the University of Göttingen found that regenerating wet and dry forests actually show opposite pathways. This implies a fundamental change in our understanding of how tropical forests change, with consequences for forest restoration and biodiversity. Results are in Nature Ecology and Evolution.
Scientists with the Universidad San Francisco de Quito and WCS Ecuador Program publishing in the journal BioTropica say that subsistence hunting in Neotropical rain forests -- the mainstay of local people as a source of protein and a direct connection to these ecosystems -- is in jeopardy from a variety of factors.
Conservation decisions based on population counts may fail to protect large, slow-breeding animals from irrevocable decline, according to new research coinciding with World Endangered Species Day.
A new study in Journal of Applied Ecology equips scientists to more accurately predict whether, and when, a species will go extinct by being more realistic about how long it takes populations to establish each new generation.
Researchers reviewed the conservation priorities for the 31 species of tenrec -- a poorly understood family of small mammals superficially resembling hedgehogs, found only on the island of Madagascar.
