Can Roads Be Used as Transects for Primate Population Surveys?
(KARGERBASEL, 2012)
Line transect distance sampling (LTDS) can be applied to either trails or roads. However, it is likely that sampling along roads might result in biased density estimates. In this paper, we compared the results obtained ...
Abundance estimation of Commerson s dolphin in the eastern area of the Strait of Magallan-Chile
(Sociedad de Biología de Chile, 2000)
Use of the video transect method for characterizing the Itacolomis reefs, eastern Brazil
(Instituto Oceanográfico da USP, 2008)
The video-transect method consists of a field survey performed with a video-camera along a line of fixed length, with the registered images further analyzed using a computer. This method was successfully applied in Brazil ...
A Comparison of four Methods to Evaluate the Butterfly Abundance. Using a Tropical Community
(Journal of the Lepidopterists' Society 45(3), 1991, 241-243, 1991-03-18)
In recent years. several transect methods to evaluate the abundance of butterflies have been proposed (Pollard, E. 1977, Biol. Conserv. 12:115—134; Feltwell, 3. 1982. Proc. Trans. Br. Entomol. Nat. Hist. Soc. 15:17—24). ...

The "Tracked Roaming Transect" and distance sampling methods increase the efficiency of underwater visual censuses
(Public Library of Science, 2018-01)
Underwater visual census (UVC) is the most common approach for estimating diversity, abundance and size of reef fishes in shallow and clear waters. Abundance estimation through UVC is particularly problematic in species ...
Density and population size of mammals introduced on a land-bridge island in southeastern Brazil
(Springer, 2007-04-01)
The introduction of alien species is one of the main threats to the conservation of native species, especially in island ecosystems. Here, we report on the population growth of 15 species of mammals introduced in 1983 on ...
