Abstract:The purpose of this study was to carry out an inventory of medium and large-sized mammal species occurring in the Mata Atlântica State Park (MASP). Located in Água Limpa municipality, state of Goiás, the MASP occupies an important area with a seasonal forest remnant, which is considered an enclave of the Atlantic Forest within the Cerrado biome. From October 2012 to December 2013, MASP's area was randomly surveyed for evidence of mammal presence. Records of 23 species of wild mammals were obtained, seven of them listed as nationally endangered. Medium and large-sized mammal species composition is characteristic of the Cerrado biome, and no endemic species of the Atlantic Forest were recorded. Richness and diversity of the mammal species recorded in MASP show the importance of this protected area for in situ conservation.
RESUMOMatas de galeria possuem grande diversidade genética e desempenham importantes funções ecológicas, como a proteção das nascentes, controle da erosão e funcionam como filtros retendo poluentes. A serapilheira, que pode ser usada como um indicativo de produtividade ecológica é amplamente coletada por meio de coletores que são distribuídos aleatoriamente em um ecossistema florestal. No entanto, a distribuição da vegetação pode apresentar dependência espacial, logo, a produtividade da serapilheira pode ser mapeada utilizando técnicas geoestatísticas o que permite a delimitação de zonas de manejo. Portanto, o objetivo deste estudo foi avaliar a eficiência de métodos geoestatísticos na delimitação de zonas de manejo da produtividade de serapilheira em uma área de mata de galeria. O estudo foi realizado na mata de galeria do córrego Lava-pés (3 ha) em Ipameri -GO, utilizando-se 60 coletores (cada um com 0,33 m² de área e suspensos a 0,65 m do solo) instalados em uma malha regular georreferenciada de 32 x 32 m. A serapilheira foi coletada mensalmente de dezembro de 2011 a novembro de 2012. Todas as amostras foram separadas manualmente nas frações: folhas (FF), ramos (FR -galhos e cascas), e estruturas reprodutivas (FER -flores, frutos e sementes) e foram expressas em kg ha -1 . Realizou-se a análise estatística descritiva e geoestatística dos dados. A produtividade de serapilheira para a FF e o total apresentou forte dependência espacial. A FR e a FER apresentaram efeito pepita puro. O mapa dos valores de serapilheira total obtido pelo método de interpolação Krigagem indicaram áreas de produtividade variando de 900 a 10.900 Kg ha -1 ano, evidenciando alta variabilidade na área. Foi possível por meio da técnica de interpolação krigagem delimitar zonas de manejo da produtividade de serapilheira na mata de galeria estudada, o que permitiu o manejo florestal específico da serapilheira. Palavras-chave: ecossistemas florestais; krigagem; dependência espacial. ABSTRACTThe gallery forests have great genetic diversity and important ecological functions, such as protecting the headwaters, controlling erosion, and functioning as buffer zones and filtering chemicals. Litterfall, which can be used as an indicator of ecological productivity, is widely collected using litter traps that are randomly distributed in a forest plot. However, vegetation distribution may present spatial dependence,
The objective of this work was to investigate forest fire damages on the structural characteristics of a 12-year-old Eucalyptus urophylla settlement located in the UEG experimental area, Câmpus Ipameri-GO. The plantation consists of an area of 0.4 há-1 ,where 75% were affected by flames. To evaluate the fire intensity, the following parameters are used: burn height, percentage of burn in relation to height and intensity the fire. For a determination of the level of burning occurred in concepts at four levels: I-surface fire without canopy burning; II-Surface fire with partial canopy burning; III-Partial consumption of the canopy by the flame; IV-Total canopy consumption by flames and / or exchange rate lethality. For trees that fit the level of burning I, II and III, it is recommended to monitor the attack of fungi and insects, in order not to compromise their increment and the final quality of the wood, the plants affected by the level of burning IV was reached the cambium. Based on the evaluation of the studied parameters, the fire intensity was classified as average in Eucalyptus urophylla of a 12 years of age. Rate lethality temperature of 60 ° C, and there was incidence of basal shoots in the stem. In order to evaluate the fire damage to the exchange, one should not only consider the external appearance of the bark, but also its thickness and the time of the fire to remain in the plantation area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
