Biodiversidade e silvicultura: abundância relativa de Nothura maculosa em plantações de eucalipto e campos nativos no Sul do Brasil

Nas últimas décadas, o agronegócio tem apresentado grande expansão no bioma Pampa. A silvicultura, principalmente com eucalipto, expandiu seu plantio no estado do Rio Grande do Sul (RS), sul do Brasil. O objetivo deste estudo é contribuir para o entendimento do impacto das florestas plantadas na biodiversidade do Pampa brasileiro, através da comparação da abundância relativa de Nothura maculosa em áreas de campo nativo e áreas com plantios jovens (6–12 meses) de eucalipto. Cães de aponte foram utilizados para definir a abundância relativa (indivíduos por hora) de N. maculosa em 16 fazendas e dez plantações de eucalipto. O total de 307 indivíduos de N. maculosa foi registrado nas 26 propriedades amostradas, sendo 188 em pastagens (média de 12,6 ind.h-1) e 119 em plantios de eucalipto (média de 13,5 ind.h-1). Não foram encontradas diferenças estatisticamente significantes entre as áreas amostradas (p = 0,18; α = 0,05). A principal conclusão deste estudo é que quando o mosaico espaço-temporal de paisagem é considerado, o termo “deserto verde” fica bastante limitado.Over the last decades, agribusiness has shown a great expansion in the Pampa Biome. Forestry, mainly with eucalyptus, has expanded its planting in the Rio Grande do Sul state, southern Brazil. The objective of this study was to contribute to the understanding of the impact of planted forests on Brazilian Pampa biodiversity, through the comparison of the relative abundance of Nothura maculosa in areas of native field and areas with young (aged 6–12 months) eucalyptus. Pointing dogs were used to define the relative abundance (individuals per hour) of N. maculosa on 16 farms and ten eucalyptus plantations. A total of 307 individuals of N. maculosa were recorded on the 26 sampled properties, of which 188 were found in grasslands (average of 12.6 ind.h-1) and 119 in eucalyptus plantings (average of 13.5 ind.h-1). No statistically significant differences were found between the sampled areas (p = 0.18; α = 0.05). The main conclusion of this study is that when the landscape spatial-temporal mosaic is considered, the term “green desert” become quite limited

Occurrence (new record) of maned wolf Chrysocyon brachyurus (Illiger, 1815) (Carnivora, Canidae) in southern Brazil

The present study presents the record of occurrence of Chrysocyon brachyurus (Illiger, 1815) in an area of wet grasslands which is adjacent to the riparian forest along Ibicui river, Rio Grande do Sul state, Brazil. The species was found through the use of camera traps and search of vestiges in pre-established transections in the area, as part of a environmental monitoring program of a forestation project

No presente estudo \ue9 apresentado o registro da ocorr\ueancia de Chrysocyon brachyurus (Illiger 1815) em uma \ue1rea de campo \ufamido adjacente a faixa de mata ciliar do rio Ibicu\ued, estado do Rio Grande do Sul, Brasil. A esp\ue9cie foi encontrada atrav\ue9s do uso de armadilhas fotogr\ue1ficas e da procura de vest\uedgios em transec\ue7\uf5es pr\ue9-estabelecidas na \ue1rea, como parte de um programa de monitoramento ambiental de um projeto silvicultural.The present study presents the record of occurrence of Chrysocyon brachyurus (Illiger, 1815) in an area of wet grasslands which is adjacent to the riparian forest along Ibicui river, Rio Grande do Sul state, Brazil.
