Snap-traps, live-traps, and baits affect the ability to capture small mammals, but few previous studies have involved sampling communities of small mammals in tropical environments. We tested differences in captures of small marsupials and rodents by Victor snap-traps versus Sherman live-traps and by two types of bait in lowland rainforest at Reserva Cuzco Amaz6nico, southeastern Peru. Snap-traps took ca. 3.5 times as many individuals as live-traps. Snap-traps also captured more species (and…

Relative efficiency of three types of small mammal traps in an African rainforest
TLDR
Three types of traps used in this study have complementary effects onto the capture of small mammals in African rainforest and an assortment of traps should always be employed in studies of small mammal communities in AfricanRainforest in order to obtain a wider range of taxa, and thus a better representation of the community.
Efficiency of four trap types in sampling small mammals in forest fragments, Mato Grosso, Brazil
We sampled the small mammal community inhabiting semi-deciduous forest frag- ments in Mato Grosso, Brazil, using 4 different types of traps, Tomahawk, Sherman, snap, and pitfall, in order to evaluate
Relative effectiveness of several bait and trap types for assessing terrestrial small mammal communities in neotropical rainforest
TLDR
Peanut butter was the most effective bait and Victor rat traps the mosteffective trap, each captured more species and individuals than any other bait or trap type.
Effects of trap type on small mammal richness, diversity, and mortality
TLDR
It is indicated that Sherman and pitfall traps capture different portions of the small mammal community and, regardless of the vegetation community, should be used in combination when assessing species richness and diversity.
Differential trapping success for small mammals using pitfall and standard cage traps in a woodland savannah region of southwestern Brazil
TLDR
The study confirms the high success rate for pitfall traps now in the Cerrado biome and suggests combinations of trapping methodologies for surveying mammalian diversity.
Comparative efficacy of Longworth, Sherman, and Ugglan live-traps for capturing small mammals in the Nearctic boreal forest

TLDR
Overall, this study found that Longworth and Ugglan traps performed similarly with respect to capturing red-backed voles and deer mice in boreal forest, however, Sherman traps were not as efficient.
Small Mammal Bait Preference and Methods of Population Size Estimation in Subarctic and Arctic Ecosystems
Small mammals are commonly captured in baited traps for management-related estimates of population size and species diversity. Bait preferences by species may alter their trappability, affecting
The usefulness of different methods for biodiversity surveys in the Amazonia / Cerrado ecotone
Small mammals and herpetofauna were surveyed in the Amazonia/Cerrado ecotone and the capture effectiveness in terms of capture rates and species richness of live traps (Sherman and Tomahawk) and
Optimising sampling methods for small mammal communities in Neotropical rainforests
TLDR
This review shows the importance of using pitfall traps in research, monitoring, and environmental impact studies on species-rich small mammal communities, and the influence of trap configuration, trap type, and sampling effort on measures of species richness and abundance.
Efficiency of small mammal trapping in an Atlantic Forest fragmented landscape: the effects of trap type and position, seasonality and habitat
  • R. Br
  • Environmental Science
  • 2014
TLDR
It is recommended that future studies of forest mammal communities, particularly those designed to test the effects of forest fragmentation, include combinations of different trap types.

Differential Effectiveness of Standard and Long Sherman Livetraps in Capturing Small Mammals
TLDR
Not only were capture rates higher in long traps, but also mortality due to predators and winter exposure was lower, suggesting that long traps might have more sensitive trigger mechanisms.
Abundance estimates of small mammals in Australian tropical rainforest: a comparison of four trapping methods
TLDR
Each method for censusing small mammals in tropical rainforest was particularly effective for 1-4 species, with factors such as diet, vertical microhabitat use, body size and trap avoidance strongly influencing trappability of different species.
Use of a Mesh Live Trap for Small Mammals: Are Results from Sherman Live Traps Deceptive?
TLDR
Two types of mesh live traps were better than Sherman traps for capturing rodents in high and low deserts, Mediterranean grassland and shrubland, and riparian woodland and scrub habitats, resulting in substantially different estimates of density, sex ratios, age structure, and movement.
The relative effectiveness of three types of traps for small mammals in some Peruvian rodent communities
TLDR
Results suggest that trap design can bias estimates of size variation and species diversity and suggest that Museum Special snap traps were the most effective in that they caught a broad size spectrum of individuals and species.
Snap and live trap efficiency for small mammals
Index trapping with small quadrats in southern Scandinavia, with either only snap or live traps, revealed significantly more trapped animals of Apodemils flavicollis (Melch.), Apodemus sylvaticus
Mammalian community structure in lowland, tropical Peru, as determined by removal trapping
TLDR
The small mammal fauna exhibited strong vertical stratification; among the 11 most abundant species, four exhibited strong biases toward terrestrial and five toward above-ground captures, indicating that either population densities were high or animals were quite mobile.
The Utility of Break-Back Traps in Population Studies of Small Mammals
TLDR
Students of small mammal populations are constantly faced with the problem of dealing with populations composed of several species with varying habitat requirements and habits, and a bias in sampling for population composition is immediately apparent.
Distribution and Ecology of Small Mammals along an Elevational Transect in Southeastern Luzon, Philippines
TLDR
Small mammals were surveyed along an elevational transect on Mount Isarog in southeastern Luzon, Philippines and recognized four trophic groups: omnivorous (three species), insectivorous-frugivory (two species), granivorous -frugIVorous (one species), and vermivorous(two species).
The relative effectiveness of two types of snap traps
TLDR
Museum Special traps removed a larger percentage of three most abundant species combined and the two most abundant rodent species considered separately than did the Victor traps.
Field Estimation of Demographic Parameters: Influence of Sigmodon hispidus Population Structure
TLDR
A method of removal trapping was initiated to test the hypothesis that different portions of a population of Sigmodon hispidus responded differently to live-trap sampling, with significant differences in body weight and distribution of size class between first and second night samples.
