“…The relative frequency of ants increased in the summer compared to winter, regardless of the type of forest. These groups have been reported as most frequent in soils of different forest ecosystems (Aquino et al, 2008;Baretta et al, 2011;Nunes et al, 2012;Cardoso et al, 2013), including the soils of the Araucaria angustifolia forest (Baretta et al, 2010), mainly due to their competitiveness in the environment (Paula and Lopes, 2013 The relative frequency of Oligochaeta was greater in RF areas, which shows the importance of this group as a good indicator of soil quality and/or environmental disruption (Baretta et al, 2007b). The other groups were Coleoptera, Chilopoda, and Diplopoda, which exhibit similar density and frequency among the areas and periods of the year evaluated.…”

ABSTRACT:Studies on soil quality in Araucaria forests contribute to understanding changes in this ecosystem and serve as a tool in conserving its biodiversity. The aim of this study was to evaluate the potential of soil macrofauna in discriminating native and replanted Araucaria forests for selection of soil quality indicators. Native (NF) and replanted (RF) Araucaria angustifolia forests were evaluated in three regions of the state of São Paulo, representing three true replications. Fifteen soil samples were collected in each area for evaluation of the physical, chemical, and microbiological properties and the macrofauna through use of monolith excavation and the manual screening method [Tropical Soil Biology and Fertility (TSBF) method]. In addition, we evaluated the weight of the surface litter dry matter and the C, N, and S contents. The abundance of macrofauna was subjected to Principal Components Analysis (PCA) and the physical, chemical, and microbiological properties were used as explanatory environmental variables for changes in the soil community. These variables and the macrofaunal properties were applied in analyses of variance and in canonical discriminant analysis (CDA) to indicate the best properties for discrimination of the forests studied. The abundance of macrofaunal groups was influenced by the state of conservation of the forest and by the sampling period; the native forest and the summer season provided greater diversity of taxonomic groups. The richness of taxonomic groups was the property that most contributes to discriminating reforested areas from native forests. The Oligochaeta group was a prominent indicator of soil quality and/or environmental disruption in Araucaria forests. Soil moisture, total porosity, and S content in the surface litter were likewise variables that contributed to distinguishing the areas. The ecological indexes (diversity, dominance, and equitability) were not sensitive to the changes in macrofaunal properties in the forests studied.

“…These results may be due to the great diversity and heterogeneity of the Formicidae, which allows many species to be positively influenced by fragmentation (Rocha et al, 2015). The presence of a large abundance of generalist ants may have contributed to the similarity between the studied sites (Lopes et al, 2010;Soares et al, 2010), which can also be explained by the fact that these insects are very territorial (Paula & Lopes, 2013) and widely distributed (Wilson, 2005).…”

Caatinga is a very important and neglected dry tropical forest biome of Brazil. Recent evidence indicates that anthropogenic threats to Caatinga have grown in recent years, and there are still gaps in the knowledge of how these effects alter biodiversity. In the present study, we evaluated the effects of vegetation structure and edge proximity on the distribution of bioindicator insects (galling insects and ants) in an arboreal Caatinga area under the influence of a monoculture in Brazil. We recorded a total of 10 species and 2,131 specimens of ants and 11 species and 29 individuals of galling insects. Species richness, abundance, and composition of galling insects and ants did not differ between edge and interior plots of the forest. Ant diversity was also not affected by the structural parameters of vegetation (plant abundance, vegetation cover, and vegetation height). On the other hand, the plant abundance positively influenced the richness and the abundance of galling insects in the plots. Our findings suggest that the distribution of ants and galling insects in Caatinga forest edge and interior environments did not differs likely due the opening of the canopy gives the arboreal Caatinga relatively homogeneous climatic characteristics throughout the forest. Already the structure of vegetation positively influences galling insects due to the high degree of dependence that endophagous life-form generates on these insects. Our results show that despite similar responses to the edge effect, ants and galling insects respond differently to vegetation structure, indicating that the structuring of these insect communities is guild-dependent.

“…Do ponto de vista físico, o uso de adubos orgânicos promove o aumento da estabilidade de agregados, associado à redução da densidade do solo (ANDREOLA et al, 2000). A macrofauna do solo tem importante papel nos processos do ecossistema no que concerne à ciclagem de nutrientes e estrutura do solo, pois é responsável pela fragmentação dos resíduos orgânicos, mistura das partículas minerais e orgânicas, redistribuição da matéria orgânica, além de produzir "pellets fecais" (BARETTA et al, 2011;PAULA;LOPES, 2013;SHUKLA et al, 2013).…”

O presente estudo objetivou avaliar o efeito de fontes de adubação em pastagem de Tifton 85 sobre a fauna edáfica e a relação desta com as variáveis físico-químicas do solo. O experimento foi conduzido em um Latossolo testando três fontes de adubação: 1) orgânica com aplicação de adubo orgânico a base de cama de aves (O); 2) orgânica + mineral O + fertilizante mineral (OM) e 3) adubação mineral (M). O delineamento experimental foi constituído de blocos ao acaso com três repetições. A coleta para avaliação da fauna edáfica foi realizada por armadilhas do tipo “Trampas de Tretzel” e, nos mesmos pontos, foram coletadas amostras de solo para análise dos atributos químicos, mensurada a resistência à penetração e umidade do solo. Houve relação entre a abundância de grupos da fauna edáfica com algumas variáveis ambientais e físico-químicas do solo, especialmente a umidade, matéria orgânica, potássio e fósforo. O tratamento O proporcionou maiores valores de abundância e diversidade da fauna edáfica, não sendo a abundância diferente do tratamento OM.Palavras-chave: Bioindicadores, fauna do solo, sustentabilidade, análise multivariada.
