ESTIMATING SITE OCCUPANCY RATES WHEN DETECTION PROBABILITIES ARE LESS THAN ONE
Nondetection of a species at a site does not imply that the species is absent unless the probability of detection is 1. We propose a model and likelihood-based method for estimating site occupancyExpand

N-mixture models for estimating population size from spatially replicated counts.
Spatial replication is a common theme in count surveys of animals. Such surveys often generate sparse count data from which it is difficult to estimate population size while formally accounting forExpand

Designing occupancy studies: general advice and allocating survey effort
TLDR
We recommend that sampling units should be surveyed a minimum of three times when detection probability is high (> 0·5 survey−1), unless a removal design is used. Expand

ESTIMATING ABUNDANCE FROM REPEATED PRESENCE–ABSENCE DATA OR POINT COUNTS
We describe an approach for estimating occupancy rate or the proportion of area occupied when heterogeneity in detection probability exists as a result of variation in abundance of the organism underExpand

Likelihood analysis of species occurrence probability from presence‐only data for modelling species distributions
TLDR
We provide a critical review of maxent as applied to species distribution modelling and discuss how it can lead to inferential errors. Expand

Estimating Size and Composition of Biological Communities by Modeling the Occurrence of Species
We develop a model that uses repeated observations of a biological community to estimate the number and composition of species in the community. Estimators of community-level attributes areExpand

Presence‐only modelling using MAXENT: when can we trust the inferences?
TLDR
We reviewed 108 articles published between 2008 and 2012 that used the MAXENT algorithm to analyse empirical (i.e. not simulated) data for species distribution modelling and found that many of these studies were ignoring important assumptions of presence-only modelling. Expand
