Estimates the total number of species from species presence-absence data on multiple sample sites or occasions using model M(h) from program CAPTURE.

Estimates patch occupancy rates and related parameters.

Computes estimates of survival and capture probability using capture-recapture data with "robust-design" models and recoveries.

Tests the null hypothesis that two samples of recoveries belong to the same bivariate distribution.

Computes estimates of survival and recovery rates for 2-age class band-recovery data.

Computes estimates of survival and capture probability for open capture-recapture models when sex is not allways known.

An R package to estimate nest abundance using a state-space superpopulation capture-recapture approach in which inference about detection proability is based on the age at first detection, as opposed to the sequence of re-detections in standard capture-recapture models.

The HyDroDSS is designed to provide water managers with risk-based information for balancing water-supply needs and aquatic-habitat protection goals to mitigate potential effects of hydrologic drought.

Generates capture-history data for given s,theta,p,c.

Overview The Stochastic Empirical Loading and Dilution Model (SELDM) is designed to transform complex scientific data into meaningful information about the risk of adverse effects of runoff on receiving waters, the potential need for mitigation measures, and the potential effectiveness of such management measures for reducing these risks.

Computes estimates of species richness using large scale data.
