Data from: On the measurement of occupancy in ecology and paleontology
负责人:
关键词:
occupancy macroecology biogeography sampling
摘要:
Occupancy statistics in ecology and paleontology are biased upward by the fact that we generally do not have solid data on species that exist but ar

摘要:
Occupancy modelling is increasingly used to monitor changes in the spatial distribution of rare and threatened species. Occupancy methods hav
Data from: Effect of detection heterogeneity in occupancy-detection models: an experimental test of time-to-first-detection methods

imperfect detection;occupancy-detection model;Phascolarctos cinereus;survey methodology
摘要:
Imperfect detection can bias estimates of site occupancy in ecological surveys but can be corrected by estimating detection probability. Time-to-fir

Black rail Connectivity Dispersal Metapopulation Occupancy modeling Parentage analysis
摘要:
1.Dispersal distances are commonly inferred from occupancy data but have rarely been validated. Estimating dispersal from occupancy data is further

摘要:
It is often highly desirable to know not only where species are likely to occur (i.e., occupancy) but also how many individuals are supported by a gi
Data from: Identifying drivers of spatial variation in occupancy with limited replication camera trap data

occupancy model;Bayesian modeling;Serengeti;camera trap
摘要:
Occupancy models are widely used in camera trap studies to analyze species presence, abundance, and geographic distribution, among other importa
Data from: Hide and seek in vegetation: time-to-detection is an efficient design for estimating detectability and occurrence

摘要:
, however, can be corrected for by estimation of detectability. In traditional occupancy models, this requires repeat or multi-observer surveys. Recent
Data from: Penalized likelihood methods improve parameter estimates in occupancy models

摘要:
1. Occupancy models are employed in species distribution modelling to account for imperfect detection during field surveys. While this approach
