Additional potential sources of error include: (1) the non-observation of species and individuals, which is related to their probability of detection (Bailey and Adams 2005; Ruiz-Gutierrez and Zipkin 2011); (2) the spatial constraints of survey techniques (for example snorkel survey transects are much more spatially limited than whole-lake VES); (3) type and complexity of the habitats being surveyed (Ruiz-Gutierrez and Zipkin 2011; for example complexity decreases the probability of detection); and (4) interannual differences in environmental conditions, such as weather and temperature at the study site (Semlitsch 1985; USEPA 2002; Bailey and Adams 2005).
These benchmarks served as fixed elevation reference points for comparing changes in soil surface elevations along our 10 permanent line transects at different survey periods.
Study site: We used three forest transects, the Cerro, Cano Palma Biological Station (CPBS), and Tortuguero National Park (TNP), located within the Tortuguero Conservation Area (ACTo) in Northeast Costa Rica.
Approximately one hundred kilometres of scat transects were walked at 31 sites in June 2013 and used to create detection histories based on 1005 spatially replicated observations using 100 m transect segments.
The Population was estimated by counting the vultures involved in active nest breeding (nesting site population) as well as, those encountered during transect surveys (transect count population).
Belt transects are a common method used to estimate the distribution of organisms within a specified area.
However, by studying multiple transects across the hybrid zone, we can explore whether selection is the primary factor maintaining the zone, and consequently the effectiveness of genitalic divergence as a barrier to gene flow.
For this reason, the objective of the presented study was to verify the results of inventories performed by hunters, using a driving census in sampling plots and snow tracking on line transects.
Along an elevation gradient through the three zones (F, FT, and AT), we laid out eight transects perpendicular to that gradient (F-l = 50 m, F-2 = 100 m, FT-1 = 100 m, FT-2 = 50 m, FT-3 = 50 m, FT-4 = 100 m, AT-1 = 100 m, AT-2 = 50 m).
transects 1 to 3), differences in means did occur and their magnitude was related to sample size (Fig.
Replicated line-transect surveys were conducted monthly on the same twelve 2 km-long transects aforementioned (Figure 1) aiming to determine changes in the local density and distribution of primates, which gave me a comparative measure of transect use intensity.
