Application of threshold concepts to ecological management problems: Occupancy of Golden Eagles in Denali National Park, Alaska Application of threshold concepts to ecological management problems: Occupancy of Golden Eagles in Denali National Park, Alaska
In this chapter, we demonstrate the application of the various classes of thresholds, detailed in earlier chapters and elsewhere, via an actual but simplified natural resource management case study. We intend our example to provide the reader with the ability to recognize and apply the theoretical concepts of utility, ecological and decision thresholds to management problems through a...

Thresholds for conservation and management: structured decision making as a conceptual framework Thresholds for conservation and management: structured decision making as a conceptual framework
A conceptual framework is provided for considering the threshold concept in natural resource management and conservation. We define three kinds of thresholds relevant to management and conservation. Ecological thresholds are values of system state variables at which small changes bring about substantial or specified changes in system dynamics. They are frequently incorporated into...

Surveillance theory applied to virus detection: a case for targeted discovery Surveillance theory applied to virus detection: a case for targeted discovery
Virus detection and mathematical modeling have gone through rapid developments in the past decade. Both offer new insights into the epidemiology of infectious disease and characterization of future risk; however, modeling has not yet been applied to designing the best surveillance strategies for viral and pathogen discovery. We review recent developments and propose methods to integrate...

Advances and applications of occupancy models Advances and applications of occupancy models
Summary: The past decade has seen an explosion in the development and application of models aimed at estimating species occurrence and occupancy dynamics while accounting for possible non-detection or species misidentification. We discuss some recent occupancy estimation methods and the biological systems that motivated their development. Collectively, these models offer tremendous...

Selecting among competing models of electro-optic, infrared camera system range performance Selecting among competing models of electro-optic, infrared camera system range performance
Range performance is often the key requirement around which electro-optical and infrared camera systems are designed. This work presents an objective framework for evaluating competing range performance models. Model selection based on the Akaike’s Information Criterion (AIC) is presented for the type of data collected during a typical human observer and target identification experiment...

The roles of competition and habitat in the dynamics of populations and species distributions The roles of competition and habitat in the dynamics of populations and species distributions
The role of competition in structuring biotic communities at fine spatial scales is well known from detailed process-based studies. Our understanding of competition's importance at broader scales is less resolved and mainly based on static species distribution maps. Here, we bridge this gap by examining the joint occupancy dynamics of an invading (barred owl: Strix varia) and a resident...
