Offspring sex ratio in birds | Wild Turkey Science #618
We deep dive into the complex mechanisms of sex determination in birds, focusing on how environmental and physiological factors influence sex ratios. Resources: Aslam, M. A., et al. (2014).

At the River's Edge: Agriculture, Flood Risk and Conservation | Wild Ag #617
What happens when floods, fish and farms all connect? Flooding is a natural process, but it can cause major problems for farms and residential areas alike. Joining us this week is Mitch Paine, Flood Risk Policy and Planning Specialist with the Washington Department of Ecology and lecturer for University of Washington's Urban Planning program, to walk us through how conservation, agriculture and flooding can all work together. From the history of flood policy in the US to modern approaches, we discuss a collective move away from trying to strictly control rivers to a more integrated and holistic flood management strategy. To showcase this approach, we look to the Snoqualmie Valley in Washington, where a collaborative effort has helped reduce flood damage while also recovering vital salmon habitat.

Which Oaks Should You Cut? | Wild Turkey Science #615
To kick off Oaktober, we break down the genetics behind why some oak trees are reliable acorn producers and others aren't, and how you as a landowner can use that variation to guide forest stand improvement decisions that benefit both turkeys and deer.

How to Pay for Wildlife Habitat Improvements on Private Land | Fins, Fur, & Feathers #614
Implementing a wildlife management plan is not cheap and the associated costs may be a barrier for many landowners to start improving their land for wildlife. Fortunately, there are a number of resources and financial assistance programs that can substantially reduce the technical and cost barriers that many landowners encounter. Join Joe and Drew as they discuss sources of technical assistance, cost-share programs, and the advantages of some of these programs that are available to landowners looking to improve wildlife habitat on their property in the Great Plains and beyond. Dr. Joe Gerken and Dr. Drew Ricketts are extension specialists and faculty members in the Wildlife and Outdoor Enterprise Management Program at Kansas State University.

Where is the line between anecdote and research? | Wild Turkey Science #613
In this episode, we discuss the difference between anecdote and research in wildlife science, limitations with unreplicated site-specific studies, how meta-analyses narrow the direction of an effect, and why seemingly conflicting results can each be right within their own context.
