Where a species occurs within a region is an important concept for many
areas of ecology (e.g., species distributions, metapopulation studies,
habitat modeling) although often a species may go undetected by field
surveys resulting in potential false absences. False absences can lead
to misleading conclusions about species occurrence.
There will be a 1-day course on species occurrence modeling that
specifically accounts for imperfect detection held on 10 July,
Albuquerque, New Mexico. For more information go to
