Water sorption behavior of short sisal fiber-reinforced natural rubber composite prepared from the natural rubber compounds from 4 clones (RRIM 600, GT 1, IAN 873, and PB 235), and from rawa, mercerized and mercerized acetylated sisal fivers were studied. Water sorption process of the composites was influenced by both, bonding agents and fiber treatments. A good fiber-matrix interface was developd from the natural rubber-mercerized/acetylated fiber composite with addition of resorcinol/hexmethylenetetramine bonding agents, as observed by SEM. Water sorption by the mercerized/acetylated fibers was about 20% smaller than for the mercerized and raw fibers. |

The Red-rumped Agouti (Dasyprocta leporina, Linnaeus, 1758) is considered common in areas where it occurs, and it is listed as Least Concern status in the IUCN red list; however, in recent decades it has been negatively affected by habitat loss and hunting. The conservation status needs to be updated since no recent studies have been conducted in the Atlantic Forest. Therefore, we aimed to estimate the density, occupancy and detectability of D. leporina in one of the larger Atlantic Forest remnants in Espírito Santo, Brazil, the Vale Natural Reserve (VNR). We surveyed four line transects between April 2013 and May 2014 to estimate density and abundance. Tomodel occupancy probability, as well as to document activity pattern, we selected 39 sampling sites with one camera-trap each. Estimated density was 21 ± 3 individuals km?2 and estimated population size was 4935 ± 368 individuals. Occupancy increases with palm density, distance from forest edge, and canopy cover. Occupancy and detectability decreases with distance from water resources. Detectability increases with palmdensity. The results presented herein can be a starting point to support future action plans for the species, making predictions regarding the ecosystem and management and conservation of D. leporina. |
