Data from: Estimating abundance of the federally endangered Mitchell’s satyr butterfly using hierarchical distance sampling
- 负责人：
- Hamm, Christopher A.
- DOI：
- doi:10.5061/dryad.v977b
- 摘要：
- . 3. I employed hierarchical distance sampling along line transects to estimate N. m. mitchellii abundance at one site in lower Michigan, USA. This method requires
Data from: Estimating densities and spatial distribution of a commensal primate species, the long-tailed macaque (Macaca fascicularis)
- 负责人：
- DOI：
- doi:10.5061/dryad.21kb2kq
- 摘要：
- provided density and abundance results much higher than the line transect distance sampling survey. Our study provides much needed baseline data
