Table 3 in Composition And Characteristics Of A Diverse Didelphid Community (Mammalia: Didelphimorphia) In Sub-Tropical South America

Table 3. Description of vegetative components of six mark-recapture grids, sampled six times between July 2015 and February 2017. Each grid included 144 traps stations (12 x 12), with trap stations placed 10 m apart. Each station included three standard Sherman traps—two placed on the ground and one located in branches or vines, 2–3 m above ground. Coordinates (latitude and longitude) indicate the center of each grid.
GridsDisturbanceDescription and locationB, HLowThe densest forest formation, associated with large trees of average height of approximately 15 meters. Tree-falls leave visible clearings, with rapid colonization of lianas covering the grasses and shrubs. Undergrowth mainly dominated by Poaceae and ferns in the most humid areas, and a very low percentage of bare soil. Grid B, -24.1412, -55.3664; Grid H, -24.1212, -55.4651.A, DMediumCharacterized by fairly homogeneous vegetation formation. Trees do not exceed 20 meters in height and average 10–12 meters in height. Soil is rather poor in organic matter, with Citrus aurantium (an invasive exotic species) distributed in several points of the plots. Undergrowth characterized by the predominance of grasses in more than 80% of the seasons, at times precluding the growth of other species. Grid A, -24.1239, -55.5048; Grid D, -24.1314, -55.4326.C, GHighVegetative conformation visibly altered by the action of past and present adjacent communities, presenting few large trees. The most frequent species forming part of the lower layer is Citrus aurantium. Forest floor characterized by a large percentage of herbaceous plants, and in most of the seasons a high percentage of bare soil is observed. The undergrowth is quite homogeneous and presents high moisture content in many parts of the plots. Grid C, -24.1316, -55.5020; Grid G, -24.1306, -55.5369.
