Introduction • Animal behavior, or Ethology, is a key component to the management and conservation of species. • The study of animal behavior is critical for elucidating consequences to species of anthropomorphic changes to habitats.
Learned Versus Innate Behaviors • Learned behaviors are those that are modified by experience • Innate behaviors are those that occur despite experience or environment.
Ibex Reintroductions • Innate behaviors may influence the success of population translocations and reintroductions
Animal Perceptions • Umwelt is a termed coined by J. von Uexkall to describe how an animal senses their environment. • Our preconceived ideas based on how Homo sapiens perceive their environment through their senses may cause a lack of success with management actions and conservation measures.
Sensory Perception • Hearing • Vision • Olfaction • Taste • Tactile • Barometric Pressure • Magnetic Fields
Hearing • Hearing • Receptors • Communication • Effects of anthropomorphic noise
Vision • Vision • Receptors • Communication • Phototaxis • Photo-pollution
Olfaction and Taste Vomeronasal organ in elk Olfaction • Receptors • Allomones • Pheremones Taste • Receptors • Conditioned taste aversion • Communication • Vomeronasal organ
Tactile • Receptors • Communication Species may shift their sensory perception of the environment based on their age, time of day, or season. Examples ticks, black bears
Forming Hypotheses About the Influence of Animal Behavior on Wildlife Management • Ultimate Hypotheses • Those involving evolution and development • Proximate Hypotheses • Those involving function and causation
Methods for Testing Hypotheses • Observations • Field Journals • Behavioral sampling • Measuring behaviors
Direct Versus Indirect Observations • Direct (observing and recording the actual behaviors) • Indirect (tracks, markings, feces, hair, etc.)
Types of Direct Sampling • Ad Libitum • Focal-Animal • Scan
Types of Measurements • Time budgets • Frequencies • Duration • Latency • Intensity • Bouts
New Tools and Concepts • Software • Activity Sensors and GPS • Robotics • Sound Arrays • High tech cameras
Managing Human Behavior • Wildlife viewing • Recreation conflicts • Habitat fragmentation • Habitat loss
Using Our Understanding of Animal Behavior to Manage and Recover Species
Summary • Animal behavior is a key component of wildlife management and conservation of species. • It is important to understand how species senses and perceptions influence their behavioral actions. • Formal hypotheses testing is an important process to understanding the role of animal behavior in managing and recovering species. • New methods and technologies are providing unprecedented information about species behaviors. • Species use of their habitats as well as foraging and mating needs can best be understood through the study of animal behavior.
