Inference about species richness and community structure using species-specific occupancy models in the National Swiss Breeding Bird Survey MUB Inference about species richness and community structure using species-specific occupancy models in the National Swiss Breeding Bird Survey MUB
Species richness is the most widely used biodiversity measure. Virtually always, it cannot be observed but needs to be estimated because some species may be present but remain undetected. This fact is commonly ignored in ecology and management, although it will bias estimates of species richness and related parameters such as occupancy, turnover or extinction rates. We describe a species

Bayes factors and multimodel inference Bayes factors and multimodel inference
Multimodel inference has two main themes: model selection, and model averaging. Model averaging is a means of making inference conditional on a model set, rather than on a selected model, allowing formal recognition of the uncertainty associated with model choice. The Bayesian paradigm provides a natural framework for model averaging, and provides a context for evaluation of the commonly...

One size does not fit all: Adapting mark-recapture and occupancy models for state uncertainty One size does not fit all: Adapting mark-recapture and occupancy models for state uncertainty
Multistate capture?recapture models continue to be employed with greater frequency to test hypotheses about metapopulation dynamics and life history, and more recently disease dynamics. In recent years efforts have begun to adjust these models for cases where there is uncertainty about an animal?s state upon capture. These efforts can be categorized into models that permit...

A traditional and a less-invasive robust design: choices in optimizing effort allocation for seabird population studies A traditional and a less-invasive robust design: choices in optimizing effort allocation for seabird population studies
For many animal populations, one or more life stages are not accessible to sampling, and therefore an unobservable state is created. For colonially-breeding populations, this unobservable state could represent the subset of adult breeders that have foregone breeding in a given year. This situation applies to many seabird populations, notably albatrosses, where skipped breeders are either...

Inferences about landbird abundance from count data: recent advances and future directions Inferences about landbird abundance from count data: recent advances and future directions
We summarize results of a November 2006 workshop dealing with recent research on the estimation of landbird abundance from count data. Our conceptual framework includes a decomposition of the probability of detecting a bird potentially exposed to sampling efforts into four separate probabilities. Primary inference methods are described and include distance sampling, multiple observers...

Filling a void: abundance estimation of North American populations of arctic geese using hunter recoveries Filling a void: abundance estimation of North American populations of arctic geese using hunter recoveries
We consider use of recoveries of marked birds harvested by hunters, in conjunction with continental harvest estimates, for drawing inferences about continental abundance of a select number of goose species. We review assumptions of this method, a version of the Lincoln?Petersen approach, and consider its utility as a tool for making decisions about harvest management in comparison to...

Exploring extensions to multi-state models with multiple unobservable states Exploring extensions to multi-state models with multiple unobservable states
Many biological systems include a portion of the target population that is unobservable during certain life history stages. Transition to and from an unobservable state may be of primary interest in many ecological studies and such movements are easily incorporated into multi-state models. Several authors have investigated properties of open-population multi-state mark-recapture models...
