Witryna25 lip 2024 · Incorporating imperfect detection when estimating species richness has become commonplace in the past decade. However, the question of how imperfect detection of species affects estimates of functional and phylogenetic community structure remains untested. We used long-term counts of breeding bird species that … WitrynaWe show that imperfect detection can substantially reduce the inferential and predictive accuracy of presence–absence and presence–background methods that do not account for detectability. While calibration is always affected, the influence on discrimination depends on the relationship of detectability and environmental variables. Main …
Witryna1 paź 2024 · Ignoring species detection in ecosystems with imperfect detection could therefore distort species richness patterns, which has implications for ecological theory, management and conservation. Ecology and biodiversity research are underpinned by species richness patterns and their environmental drivers. However, a key topic in this … Witryna30 paź 2014 · The probability that an article incorporated imperfect detection increased with time and varied among taxa studied; studies of vertebrates were more likely to incorporate imperfect detection. Among articles that reported detection probability, 70% contained per-survey estimates of detection that were less than 0.5.
Witryna6 kwi 2024 · A plethora of additional survey designs that address imperfect detection may also be compatible with satellite imagery. Replicated point counts (Royle 2004) can collect multiple counts from each site using multiple images from repeat satellite overpasses, which may help to estimate how many animals are using unsearchable … Witryna10 kwi 2024 · Occupancy-detection models are widely used in ecology to estimate the probability a site is occupied by a species while accounting for imperfect detection. These are a type of hierarchical model usually fitted using dedicated software (White …
