TL;DR: In this article, the authors evaluated the feasibility of using bioacoustics to simultaneously monitor a common but declining species and a rare but increasing invasive competitor within a site occupancy framework, and found that passive-acoustic monitoring can be used to detect small but potentially biologically meaningful changes in site occupancy for multiple species with very different population dynamics with high confidence.

TL;DR: A load forecasting performance discrimination between the artificial occupancy attributes is realized demonstrating that using the most complex indicator increases the workload and complexity while not improving the load prediction significantly.

TL;DR: Systems such as this, where turnover is driven by habitat dynamics, demonstrate the potential value of incorporating the dynamics of habitat change into metapopulation models, and are likely to improve predictions of landscape-scale occupancy dynamics, whilst also allowing patch-level predictions of occupancy, based on local habitat conditions.
Abstract: Simple metapopulation models assume that local populations occur in patches of uniform quality habitat separated by non-habitat. However field metapopulations tend to show considerable spatial and temporal variation in patch quality, and hence probability of occupancy. This may have implications for the adequacy of simple metapopulation models in describing and predicting regional population dynamics of natural systems. This study investigated the effects of habitat characteristics on landscape-scale occupancy dynamics of two species of backswimmer (Notonecta, Hemiptera: Notonectidae) in small freshwater ponds. The results demonstrated clear links between habitat, pond occupancy and population turnover, particularly local extinction. There were considerable changes in the habitat of individual ponds between years, but local changes were not spatially correlated and the frequency distribution of habitat conditions at the landscape level remained similar in different years. Stable occupancy levels of Notonecta species appears to result from a balance of the rates of creation and loss of suitable habitat due to spatially uncorrelated habitat change. Systems such as this, where turnover is driven by habitat dynamics, demonstrate the potential value of incorporating the dynamics of habitat change into metapopulation models. Such developments are likely to improve predictions of landscape-scale occupancy dynamics, whilst also allowing patch-level predictions of occupancy, based on local habitat conditions.

TL;DR: In this article, the authors used measured occupancy data from a real office building to evaluate the performance of an agent-based occupancy simulation model: the Occupancy Simulator, which can simulate a range of occupancy presence and movement behaviors for regular types of occupants.

TL;DR: Analysis focused in particular on occupancy ratios by funding status, shelter size, metropolitan statistical area (MSA), season, and day of the week.
Abstract: Data from a nationally representative sample of shelters for runaway and homeless youths (N = 160) were analyzed to determine shelter capacity, occupancy, and occupancy ratios. Analysis focused in particular on occupancy ratios by funding status, shelter size, metropolitan statistical area (MSA), season, and day of the week.
