Registros de Collembola (Arthropoda, Hexapoda) no Estado do Rio Grande do Norte, Brasil

Abstract

Abstract:The state of knowledge of collembolans in Brazil is deficient and most biomes are poorly sampled. This paper provides a list of species of Collembola from Rio Grande do Norte State. The samplings were carried out in the municipalities of Extremoz, Natal, Parnamirim and Serra Negra do Norte, by using pitfall traps, light traps and direct collections. Sixteen species of springtails were recorded, distributed in 12 genera and seven families. The family with the highest diversity was Entomobryidae, with seven species. The most speciose genus was Seira, with four species. Only two species were recorded in Caatinga and they both were also reported to areas of Brazilian Atlantic Forest. However, these species are new to science, which indicates the urgency of a full inventory in Caatinga, an underestimated domain. Five new species of Collembola were found in the State.

The Effects of Glyphosate and Multrazine on the Abundance and Diversity of Soil Microarthropods at the University Park, University of Port-Harcourt, Nigeria

“…The results of this study support the hypothesis that different herbicides have different effects on the population densities of soil micro arthropods. This assertion is also supported by the findings of [2] who reported that micro arthropods populations were different under different types of herbicide treatments. Similarly [4,26,28] also recorded variation in soil faunal populations due to application of various agrochemicals.…”

“…The dominance of Oribatida recorded among soil micro arthropods has also been extensively recorded by [2,8,26] that their high numbers may be associated with wide range of their feeding habits. They feed on both living and dead organic materials [5,32] made the same observation which was also affirmed by the observations of [33] that oribatid mites are among the most numerically abundant and diverse soil mesofaunal species.…”

“…Micro arthropods, in particular the Oribatid mites and Collembolans are the most abundant and diverse arthropods living in soil and litter environments [1,2]. Different herbicides have different effects on the abundance and diversity of soil microarthropods.…”

Temporal variations of Collembola (Arthropoda: Hexapoda) in the semiarid Caatinga in northeastern Brazil

“…Twenty-nine species of Collembola have been reported from areas of Caatinga vegetation in Brazil, including the results of the present study (BELLINI & ZEPPELINI 2009, SANTOS-ROCHA et al 2011. The species richness of Collembola in this biome Figure 1.…”

“…BELLINI & ZEPPELINI (2009) noted that northeastern Brazil has one of the highest species richnesses of this genus in the world. Twenty-five species of Seira have been reported from Brazil, with 14 recorded in the Caatinga region (BELLINI & ZEPPELINI 2009, SANTOS-ROCHA et al 2011.…”
