Species' assessments must frequently be derived from opportunistic observations made by
volunteers (ie, citizen scientists). Interpretation of the resulting data to estimate population …

In the early 1990s, biologists began experimenting with camera traps to estimate the
abundance of tigers Panthera tigra in the Nagarahole National Park (Karanth 1995) …

Predicting the distribution of endangered species from habitat data is frequently perceived to
be a useful technique. Models that predict the presence or absence of a species are …

Assessment of abundance, survival, recruitment rates, and density (ie, population
assessment) is especially challenging for elusive species most in need of protection (eg …

Aim Species often remain undetected at sites where they are present. However, the impact
of imperfect detection on species distribution models (SDM s) is not fully appreciated. In this …

Monitoring is an integral part of species conservation. Monitoring programs must take
imperfect detection of species into account in order to be reliable. Theory suggests that …

Species' distribution models (SDMs) attempt to predict the potential distribution of species by
interpolating identified relationships between species' presence/absence, or presence-only …

Recent advances in occupancy estimation that adjust for imperfect detection have provided
substantial improvements over traditional approaches and are receiving considerable use in …

Wildlife biologists use knowledge about wildlife‐habitat relationships to create habitat
models to predict species occurrence across a landscape. Researchers attribute limitations …

Summary 1 Over the last 30 years there has been a great deal of interest in investigating
patterns of species co‐occurrence across a number of locations, which has led to the …
