Conservation Maven reviews the latest groundbreaking research and books in the field of conservation.
A new study published in the journal Biological Conservation illustrates how landscape genetics can be used to discover how wildlife populations respond over time to anthropogenic and natural forest disturbances.
Stephen Spear and Andrew Storfer from Washington State University conducted genetic sampling of Rocky Mountain tailed frogs (Ascaphus montanus) across north-central Idaho at sites that were either subject to timber harvesting or historic wildfires and found that the responses to the ........

Spear, S., & Storfer, A. (2010) Anthropogenic and natural disturbance lead to differing patterns of gene flow in the Rocky Mountain tailed frog, Ascaphus montanus. Biological Conservation. DOI: 10.1016/j.biocon.2009.12.021
A new study from Northern California finds direct evidence that warming oceans leads to increased dominance of non-native species in coastal marine areas. Researchers collected a number of native and exotic species and subjected the organisms to different water temperature levels in a laboratory setting...... Read more »

Scientists have presented an interesting method for measuring the success of ecological restoration. The basic concept of the habitat affinity approach is that it assesses the degree to which the species composition at a restoration site reflects that of the target habitat community......

Two new articles in the journal Frontiers in Ecology and the Environment show that dramatic expansion of biofuel agriculture may reduce biodiversity and promote the spread of invasive species. The articles also make a number of recommendations for reducing the ecological impact from biofuel production. ... Read more »

Wildlife biologists in Virginia have devised a new method for designating species as common or rare based on quantitative analysis of geographic distribution, abundance, and habitat specificity. The approach is designed to provide a rigorous framework that managers and conservationists can use to define priorities and strategies for protecting imperiled species...... Read more »

A new case study presents a planning method for prioritizing ecosystem restoration efforts across an agricultural region. While this type of systematic approach to prioritization has been widely used in land protection, it is much less common in restoration...... Read more »

Researchers from New York have presented an approach to help teachers better integrate conservation biology into the high school classroom. This is important because teaching conservation biology to students could play a key role in influencing people to "pursue careers or live lifestyles that would reduce the negative impact of humans on the world."
Yet, in the United States - and probably many other countries - few secondary schools have specific classes in conservation biology. ... Read more »
