Fence Ecology by Amy Koehler
I am a wildlife ecologist equipped with spatial and quantitative tools. I am broadly interested in spatial and community ecology of hoofed mammals (both wild and domestic) in working landscapes where humans and wildlife share space. I focus on arid and semi-arid rangelands, from Asian steppe, American West, to African savanna, systems that support wide-ranging wildlife as well as extensively herded livestocks. Some of the keywords of my research are: animal movement, fence ecology, landscape connectivity, pastoralism, mobility, fragmentation, social-ecological systems.

Below are the research themes I am currently pursueing: 

Animal movement in a changing world

A framework of migratory plasticity in ungulates.
Movement is a fundamental way through which individual animals respond to and interact with their external environments. Understanding whether, when, where, and how animals move does not only enrich our knowledge on ecology of the target species, but also shed light on mechanisms of how various ecological processes connect across scales. These information are vital for biodiversity conservation and management in a changing world.

Linear infrastructure, particularly fences, in social-ecological systems
 Fences might be one of the most prevalent, yet least understood, linear infrastructure on earth. Ecologically, fencing can alter animals physiology, movement patterns, habitat use, and ecosystem processes. Often embedded in socio-ecological systems such as rangelands, fences also play a fundamental role in land practices, economic relationships, and social relationships in societies. My research contribute theoretically and empirically to the bourgeoning field of fence ecology.

The Wires that Shape the World: Fence Ecology and Conservation
Fencing is one of the most widespread manmade features on Earth, yet they are often omitted from discussions of humanity’s impacts on the environment. Following my journey from the Tibetan plateau to the Greater Yellowstone Ecosystem, I shared the hidden ecological impacts of the wires that have shaped the world.

Linking ecology and conservation

From the Greater Yellowstone Ecosystem to the Yangtze River of China, human activities are gradually encroaching wildlife habitats and altering animal behaviors. Utilizing my technical expertise in GIS and remote sensing, I collaborate with researchers and managers around the world to investigate how wildlife distribution respond to lethal and non-lethal human activities, such as urban development, prescribed burning, sand mining, and agriculture.
