River Streams Benefit from Fallen Trees

Rivers have suffered the most from human urbanization. Damming, river straightening and removal of large woody debris have disrupted many natural processes essential for healthy habitats of fish, insects and algae. Many land managers have returned fallen trees back into rivers in hopes to improve habitat quality. It wasn’t until this research by Thompson and colleagues that there was clear evidence that this management strategy was successful.

Climate change altering wine-making: from landscape to conservation

Our changing climate (Marcott et al., 2013) is at the forefront of global politics and economic planning decisions. There is growing evidence that climate change will affect most fields of study and many professions from agriculture to zoning. One such field that is gaining attention is viticulture, or wine production. A study published in PNAS led by Dr. Hannah and colleagues (2013) looked at how changes in temperature and precipitation will affect global wine production. In addition, the researchers explored how the locations of wine-making regions may shift due to climate stress, and how this might affect conservation.

Ocean acidification in the face of many environmental stressors

Greenhouse gas emissions are acidifying the ocean. The progressive decrease in ocean pH, or ocean acidification, is impacting ecosystems across the globe. Despite our understanding of the severity of ocean acidification’s impacts on individual species, the story is more complicated. We must also consider more broadly how ocean acidification affects ecosystems that are also exposed to a variety of other stressors such as changes in temperature and oxygen, coastal nutrient input, fishing, and ocean commercial transportation. It is critical that future adaptation and mitigation strategies consider how these co-occurring stressors interact with one another.

Reputation (of Conservation Planning): Challenges in the Face of Climate Change

We could make a whole list of habitats to conserve, but which are in red, underlined? Scientists recently tested a number of models incorporating the impacts of climate change to find out what method we should be using for predicting high value conservation areas in the future.
