Hamel Manoelle Fuzaro Gullo Agrociencias Quercus Peromyscus Disturbance disturbance program capture Oak species form a conspicuous and often dominant component of bottomland forests of the Mississippi Alluvial Valley. The extent of these forests has be en drastically reduced as a result of clearing for agriculture in the past two centuries. Patterns of clea ring have reduced the distribution of remaining fore st patches to a much more lood-prone subset of the landscape than was historically the case, reducing the diversity of oak species currently present on t he landscape. Intensive harvesting has further changed the composition of the remaining stands. Small rem- nant patches of primary forest continue to exist as Research Natural Areas on the Delta National For- est in Sharkey County, Mississippi. In particular, the Overcup Oak ( Quercus lyrata ) and Redgum (Liq- uidambar styracilua ) Research Natural Areas pres- ent substantial components of the trees for which t he areas were named, as well as Quercus nuttallii and smaller components of other species. Recent interes t in afforestation has produced a resurgence of inter est in restoration of oak forest to abandoned farmland in the region. We have studied small mammal response to restoration on an extensive experiment near the Delta National Forest since 1995. We have also examined small mammal response to a tornado that disturbed approximately half of the Overcup Oak Research Natural Area in 2008. We use these studies to demonstrate how population estimates of small mammals can be obtained from capture-recapture studies, employing different designs, and utilizing Program Capture for population estimation. Small mammal communities in these stands are more species-rich in early succession than in primary fo rest. The study of response to tornado damage to the Overcup Oak Research Natural Area is complicated by the fact that this particular forest type is ver y lood-prone, creating obstacles to colonization by small mammals. Analysis of capture-recapture data with robust methods illustrated in this study permi ts extraction of more information from the same ield effort expended in time-consuming small mammal trapping studies that have been subjected to less detailed analysis. Our work may prove useful to other s interested in study of small mammals in oak forest systems in Central and South America. 2010 artículo científico 0120-0739 https://www.redalyc.org/articulo.oa?id=423939615009 en http://www.redalyc.org/revista.oa?id=4239 Colombia Forestal application/pdf Universidad Distrital Francisco José de Caldas Colombia Forestal (Colombia) Num.2 Vol.13 |
