Hillside of village sacred forest with view of valley below

Sacred Forests in northwest Yunnan, China - a conservation priority?


Village sacred forests are small village forests protected as part of people’s religious beliefs and not because they are important to wildlife or air quality, and therefore may be better conserved without “official” conservation status.

The differential importance of aquatic insect productivity on terrestrial, insectivorous bird guilds.


Aerial insectivore birds have experienced population declines while other insectivore guilds have not. Paul’s research shows that aerial insectivore abundance is related to aquatic insect emergence, while gleaner abundance is not.

It is getting weirder - extreme events in satellite records


Extreme weather events are becoming both more frequent and intense. These events could be shifting bird numbers and their normal distributions in the United States. Ultimately, these weather events could lead to the extinction of highly-sensitive species.

If you can't stand when it gets dry, fly north: Dickcissels reliably track extreme weather events in the Midwestern United States


What happens when it gets too dry? Brooke Bateman discovers how migratory birds like Dickcissels respond to extreme drought events in the Midwestern United States and looks at what that means for future management and conservation efforts.

Massaging the U.S. Census to look at the WUI and at housing growth trends


Dave Helmers sits down with me and gives the skinny on how he turns U.S. Census data into ecologically relevant products for answering some of the most pressing questions in land-change conservation science.

Housing development is eroding the value of protected lands


Locations in and around natural areas are especially appealing for housing development. Unfortunately, this development may have undesirable consequences.

How are birds breeding in New England affected by the weather?


Do we know how climate change and extreme weather conditions affect wildlife in particular bird populations?

Forest Songbirds and Extreme Weather: How do Drought, Heat Waves, and Cold Snaps Affect Birds?


Global climate change is increasing the incidence of extreme weather events. Jessica Gorzo, PhD candidate, is studying how these extreme events are affecting the abundance, geographical distribution, and breeding habits of forest songbirds.

Necessity spawns plasticity: Siberian Cranes abandon specialist foraging behaviors after an extreme flood event


James Burnham builds on his research at Poyang Lake following a 4-month stint in the field. During the winter of 2010/2011, he saw birds he has been studying for years in unexpected places and behaviors never before documented.

Do we help birds when we help butterflies? Effects of oak savanna restoration for Karner blue butterfly on savanna bird communities


The Karner blue butterfly, a federally endangered species, has suffered major population declines mainly due to habitat loss since European settlement. Eric Wood investigated if restoration of oak savannas, critical habitat for this species, also provides an opportunity to protect important avian communities that use sparse canopy oak savannas during the breeding season.

Predicting Broad-scale Patterns of Avian Biodiversity with Landsat Image Texture


There is not a map that predicts bird species biodiversity for the whole United States at scales that are relevant for a forester or a county planner. However, such a map is utterly needed to make realistic conservation plans.

How are fires in western Mexico affecting hummingbirds?


Professor Sarahy Contreras has been studying hummingbirds in western Mexico for nearly 20 years. Her current project tackles the question of how different frequencies and intensities of post-fires affect hummingbird populations in the Sierra de Manantlan Biosphere Reserve.

New multi-scale landscape indices for spatial pattern analysis


Understanding how spatial patterns of vegetation explain the distribution of organisms is a central theme within Landscape Ecology. Avi Bar Massada developed a novel method to quantify these patterns, which may be more effective than existing methods. He illustrates its effectiveness with bird data from Wisconsin's Fort McCoy.

Modeling habitat use patterns of critically endangered Siberian Cranes and other wintering waterbirds in Poyang Lake, People's Republic of China


Poyang Lake, one of China's most diverse wildlife areas, increasingly faces shifting use patterns and new threats to the wildlife and human communities who call it home. Ph.D. candidate James Burnham seeks to understand how changing lake hydro-dynamics and human impacts affect the local wildlife, particularly the critically endangered Siberian Crane.

If you build it, they will come - but can you still conserve biodiversity?


If you build it, they will come is a cliche, to say the least. In the context of parks, recreation trails, and conservation of biodiversity, Marty Pfeiffer offers a new twist on the old cliche: If they come, can you still conserve biodiversity?

The potential of image texture for measuring vertical vegetation structure


Vegetation structure is an important habitat attribute characterizing bird habitat. Measuring vegetation structure in the field is time consuming and thus inefficient across large scales. Eric Wood is exploring whether use of a metric called image texture derived from satellite and aerial images can potentially streamline the process of assessing vegetation structure and facilitate prediction of bird distribution across large areas.
