Why weren't New World rabbits domesticated?

"...Recent work by archaeologists Andrew Somerville of Iowa State University and UC Riverside's Nawa Sugiyama found a simple answer: European rabbits live readily in large social groups while American cottontail rabbits do not. The less social nature of American cottontails combined with greater species diversity created a situation where rabbit husbandry did not lead to domestication..."

Individual protected areas in Amazonia differ greatly in how effectively they help to fight deforestation and carbon emissions

"...Tropical forests are unique environments that have huge species diversity and also act as important reservoirs of organic carbon, thereby counteracting climate change. However, their area is diminishing due to deforestation, which gives reason to worry both about the survival of their biodiversity and about the increasing carbon emissions. To help to optimise conservation efforts, it is important to understand how well conservation areas succeed in safeguarding tropical forests..."

Restoring Native Grasslands to Help Birds JSTOR Daily

"...Grasslands have many ecosystem values: soil conservation, flood mitigation, and habitat for a plethora of species, particularly birds. Birds rely on the grasslands for habitat and food sources, and in turn, they disperse seeds and control insect populations. As grasslands shrink, so does habitat for many bird species..."

Many nonprofits, companies report using commercial species in tree planting projects

"..."We found some organizations placed an emphasis on biological diversity and forest restoration in their mission statements. When we looked at the species they reported planting, many organizations reported planting commercial species, with chocolate, mango and teak in the top five," said the study's first author Meredith Martin, assistant professor of forestry and environmental resources at NC State. Martin led the study with researchers from The Nature Conservancy, a nonprofit that was also included in the analysis..."

Do's and Don'ts / Save Owl's Head

"...Shallow marine environments have been degraded by human intervention to disastrous extents. Along the Northeastern shores of North America, about ¾ of all eelgrass is gone – as a result of degraded water quality, caused by pollution that causes eutrophication (oversupply of nutrients, leading to a decline in species diversity and a rise in opportunistic single species), overfishing, massive sedimentation and disease. But while Nova Scotia’s shores, especially our Eastern shore, are still relatively undeveloped, warming oceans also pose a threat to these ecosystems..."

The Importance of Old Growth Forests The Nature Trust of British Columbia

"...Old growth forests are awe-inspiring and highly diverse ecosystems that can be found all around the world. They play essential roles in wildlife habitat, species diversity, hydrological regimes, nutrient cycles, carbon storage, and numerous other ecological processes. They have special structures and characteristics that provide habitat for animal and plant species, such as bats, birds, lichen, and mammals which are not found in any other forest types..."

Interdependence between climate change and biodiversity

"...IMAGE: There is much emphasis on the undesirable feedbacks where climate change drives biodiversity loss (magenta arrows feedback). Here, we highlight the contribution of an underutilized positive feedback in which biodiversity-dependent..."

Climate change a bigger threat to landscape biodiversity than emerald ash borer

"...The researchers looked at moderate and high-level climate change scenarios based on a business-as-usual approach that fails to curb greenhouse gas emissions within the next decade. The landscape itself partly drove the team's decision to study these scenarios, Olson said. The forest sits in what scientists call a tension zone, where vegetation, soil type and climate variability can shift quickly as one moves across the landscape..."

Tree species diversity is no protection against bark beetle infestation

"...In recent years, foresters have been able to observe it up close: First, prolonged drought weakens the trees, then bark beetles and other pests attack. While healthy trees keep the invaders away with resin, stressed ones are virtually defenseless. Freiburg scientist Sylvie Berthelot and her team of researchers from the Faculty of Environment and Natural Resources and the Faculty of Biology are studying the importance of tree diversity on bark beetle infestation..."

Two biodiversity refugia identified in the Eastern Bering Sea

"...Marine biodiversity, the diversity of life in the seas and oceans, supports ecosystem services of immense societal benefits. However, climate change and human activities have been adversely affecting marine biodiversity for many decades, resulting in population decline, community shifts, and species loss and extinction. Developing effective means to mitigate this rapid biodiversity loss is vital..."
