For the most part, this book concerns itself with measurement data and the corresponding analyses based on normal distributions. In this chapter and the next we consider data that consist of counts. Elementary count data were introduced in Chapter 5. Frequently data are collected on whether or not a certain event occurs. A mouse dies when exposed to a dose of chloracetic acid or it does not. In...

Mountain caribou, an ecotype of woodland caribou (Rangifer tarandus caribou), are a species at risk and so are a primary focus in forest management in the Columbia Mountains Forest District. Two multivariate habitat models have been developed based on telemetry data to predict caribou habitat by associating forest cover and physiographic variables at various spatial scales and seasons: one usin...

Detailed empirical models predicting both species occurrence and fitness across a landscape are necessary to understand processes related to population persistence. Failure to consider both occurrence and fitness may result in incorrect assessments of habitat importance leading to inappropriate management strategies. We took a two-stage approach to identifying critical nesting and brood-rearing...

Statistical modeling of presence-only data has attracted much recent attention in the ecological literature, leading to a proliferation of methods, including the inhomogeneous poisson process (IPP) model [15], maximum entropy (Maxent) modeling of species distributions [12] [9] [10], and logistic regression models. Several recent articles have shown the close relationships between these methods ...
