Mammal groups have a vast variety of habitats, which include aquatic, aerial, arboreal, and terrestrial. For terrestrial habitats, camera traps are used as a common technique to record mammals and other vertebrates and have been recently utilized to observe arboreal animals as well. Here, we compare the difference in mammal diversity between floor and canopy strata and evaluate the use of camera trapping in a lowland forest in central Amazon. We installed nine paired camera traps, one in the canopy stratum and other in the floor stratum, in the Alto Cuieiras Biological Reserve (Brazilian Amazon). With a sampling effort of 720 camera-days, we recorded 30 mammal species: nine in canopy strata, 14 in floor strata, and seven in scansorial strata (sharing both strata). On the forest floor, the species with the greatest abundance was Myoprocta acouchy; in the canopy, Isothrix paguros had the greatest abundance; and among the scansorial species, Proechymis sp. was the most abundant. Our results show the differences in mammal diversity between floor and canopy strata; canopy strata contained more small and frugivorous mammals. Although we obtained a relatively low sampling effort with the camera-trap method compared with other studies utilizing different techniques, our results were especially similar to those of previous studies that worked with canopy and floor strata. Thus, camera trap can be very effective for recording short periods of time, and this method is less physically exhaustive and expensive for researchers to study vertical strata.

ABSTRACT. Monthly catches were caITied out during five days/month in the Adolpho Ducke Forest Reserve (Manaus, Amazonas), from FebruaIy 1990 to JanuaIY 1991 in order to assess the sand fly fauna of that region, evaluate the atractivity of these insects with regard to different kinds of traps and baits and to know vertical stratification of these insects. The traps and baits used in catches were: Disney traps with baits: Didelphis sp., Gallus sp. and Mesocricetus sp.; CDC light traps at three vertical levels (I m, 5m and 10m); Suspended trap (5m) and Malaise trap (I m) and catches on bases of tree-trunks. The most efficient type was the CDC. Malaise and Suspended did not collect specimens of Culicoides Latreille, 1809. The Disney traps with baits only attracted specimens of C jusipalpis Wirth & Blanton, 1973 . In vertical stratification, the CDC trap placed at I m caught 898 specimens of nine species; at 5m 895 specimens were collected which belonged to 13 species; and at 10m 224 specimens of 14 species were collected. Two thousand and fotty-six specimens of Culicoides were captured, being about 5,66% males and 94,34% females, which belonged to 17 different species; the most frequent were Cjusipalpis (43,05%), followed by C pseudodiabolicus Fox , 1946 (32,79%), C hylas Macfie, 1940 (12,31%) and Cjoxi Ortiz, 1950 (3,71%) . The other 13 species totalized 8, 15%.
