The Sieving Lab: Avian Ecology and Conservation Behavior
Conceptually rooted in behavioral, community, landscape and evolutionary ecology, my lab focuses on avian ecology and behavior with a central focus on the behavioral mechanisms underlying human-bird-envieronment interactions. Recent research in my lab addresses:
- Conceptual frameworks and applications of mixed species flocking
- Avian acoustic and communication ecology; especially of family Paridae
- Noise, predation risk, and habitat loss effects on avian behavioral, population and community ecology
I am enthusiastic about graduate training! Grad students are the lifeblood of scientific advancement and academic communities of learning. My lab philosophy is ‘effective conservation science is via rigorous research design’. Ecosystems are complex and conservation is emotionally and economically pressing for stakeholders and the public. Therefore, conservation scientists must work and learn efficiently while maintaining scientific standards at the highest level. I teach a foundational graduate course in scientific logic and conceptual framing (ecological science), research organization, and competitive proposal writing (WIS 5496 Research Design in Widlife Ecology and Conservation). My gradaute students' interests take the lab in their directions. My philosophy of mentoring - ‘it’s your degree and future - take the reins!’
Sieving Lab - Anchor Conceptual Frames
Animal Information Landscapes
When the titmouse speaks, everybody listens! We’ve discovered that the Eastern Tufted Titmouse encodes a high diversity of reliable and distinctive information about predation threats they perceive in their alarm calls and other vocalizations (including their chip calls). Many other species not only know the titmouse code, they change their behaviors in accordance with the degree of threat conveyed in those calls. We are exploring many aspects of parid ‘info-scapes’. See Publications list. This work has been funded by National Science Foundation; University of Florida; Animal Behavior Society; others.
Vocal Complexity in Family Paridae
Causes and consequences of the extraordinary vocal complexity of chickadees and titmice. With Todd Freeberg (lead PI: UT-Knoxville) and Jeff Lucas (Purdue) we tested three major hypotheses for the causes (social, habitat, and predation risk complexity) of parid vocal complexity. While all three factors clearly influence avian communication, in Paridae, the social context is key. A central finding of our work is that the composition of mixed species audiences is highly influential regarding when and how vigorously chickadees and titmice vocalize and comunicate. In aggression, territorial defense, mixed species flock interactions, and mobbing; the identities of nearby species affect callers' vocal output. Heterospecific audience effects are increasingly recognized as important determininants of all aspects of avian communication. Work funded by NSF.
Behavioral Landscape Ecology of Forest Animals
Principles of Behavioral Landscape Ecology are fundamental to understanding the distribution and viability of wildlife populations. Behavioral mechanisms help determine spatial distributions of animals and their responses to landscape change (short and long term) and disturbance. We use behavioral ecology to understand animal movements, activities, and distribution in disturbed landscapes. We have found that landscape connectivity is defined by a species’ behavioral perceptions of risks and rewards in spatial decision-making, and is greatly influenced by spatial configuration of habitat and also what other species are doing nearby at local and landscape scales.
