![]() The study of populations and communities of a large number of animal species, especially those with a cryptic life-style, requires capture-recapture data from traps. 2012 Dray S, Pélissier R, Couteron P, Fortin MJ Legendre P, Peres-Neto PR, Bellier E, Bivand R, Blanchet FG, Cáceres M, Dufour AB, Heegaard E, Jombart T, Munoz F, Oksanen J, Thioulouse J, Wagner HH (2012) Community ecology in the age of multivariate multiscale spatial analysis. Efficient sampling techniques facilitate the use of sampling designs that result in large samples, which are important for advancing both ecology and conservation ( Dray et al. London, Academic Press, 817p., Magurran & Macgill 2011 Magurran AE, Mcgill BJ (2011) Biological Diversity: Frontiers in Measurement and Assessment: Frontiers in Measurement and Assessment. 2002 Williams BK, Nichols JD, Conroy MJ (2002) Analysis and management of animal populations: modeling, estimation, and decision making. Studies focusing on hypothesis testing in population and community ecology, and those aiming at monitoring populations and communities for practical purposes, rely on efficient sampling ( Williams et al. Obtaining high-quality data on animal populations and communities in an efficient manner is paramount to a variety of ecological studies. While pitfall traps captured a larger number of individuals and a higher proportion of juveniles, Sherman traps provided higher recapture rates for most species.Ībundance biodiversity survey demography richness trapping protocol. Studies focusing on demographic parameters require the combined use of pitfall and Sherman traps. Large pitfall traps should be used whenever the focus is on biodiversity and community parameters, since they captured more individuals and species. Our findings highlight that trap efficiency depends not only on the quantities considered (species, individuals or recaptures), but also on animal characteristics and weather conditions. We evaluated if mortality rates and the capture-recapture success of small mammals varied between two types of trap (Sherman and pitfall), and if the capture success of each type varied with age and sex of individuals, and with weather conditions. The dataset contains data on 3608 captures of 1273 individuals from 24 species of Atlantic forest small mammals. Here we contribute to close this knowledge gap by focusing on a large capture-recapture dataset from three 2-ha grids monitored for approximately two years (totaling 55.000 traps-night) in the Morro Grande Forest Reserve, São Paulo, Brazil. Integrative approaches that address the simultaneous effects of these factors on capture-recapture success are rare. In many instances these data come from live-trapping, the success of which depends on various factors, such as the interaction between the trap's mechanisms and the morphological or ecological characteristics of the animals, and weather conditions that can affect both trap efficiency and animal behavior. ![]() Efficiently obtaining high-quality data on animal populations and communities is paramount for ecological and conservation studies. ![]()
