Abundance and stratification of soil macroarthropods in a Caatinga Forest in Northeast Brazil

Abstract: In arid and semiarid environments, seasonality usually exerts a strong influence on the composition and dynamics of the soil community. The soil macroarthropods were studied in a Caatinga forest located in the Reserva Particular do Patrimônio Natural (RPPN) Fazenda Almas, São José dos Cordeiros, Paraíba, Brazil. Samples were collected during the dry and rainy seasons following the method proposed by the Tropical Soil Biology and Fertility Program (TSBF), with minor modifications. At each station, 15 soil block… Show more

“…Despite their key role in the functioning and development of ecosystems, edaphic macrofauna is still poorly explored in ecological restoration (Araújo et al, 2010;Jouquet et al, 2014) and not commonly included in evaluation of restoration success (Ruiz-Jaen and Aide, 2005;Wortley et al, 2013).…”

“…In a previous study, Araújo et al (2010) found, in the top layer of the soil from Caatinga forest, an abundance of 14% of insects, in larval stage, during the rainy season and only 3.8% of insects under water stress conditions. Means followed by the same letter in the column did not differ statistically from each other by the Tukey's test (P <0.05).…”

“…The abundances and biomasses of termites at the dry tropical forests site did not demonstrate significant variations between the dry and rainy seasons. Other studies undertaken in seasonally dry tropical forests in the region, however, demonstrate an effect on vertical distribution, foraging and abundance of insects in general (Moura et al, 2006;Araújo et al, 2010;Vasconcellos et al, 2010a), including termites (Melo & Bandeira, 2004;Vasconcellos et al, 2010b). Apparently, other characteristics, such as food availability, soil moisture, and interspecific interactions, could minimize climatic effects on soil fauna in seasonally dry tropical forest ecosystems.…”

“…Arthropods occupying the leaf litter/soil complex are generally influenced by the climatic characteristics of the host ecosystems (Adis et al, 1989;Harada & Bandeira, 1994;Dibog et al, 1998;Pinheiro et al, 2002;Doblas-Miranda et al, 2007). The assemblage structure and foraging of termites in the Neotropical region have been observed to be associated with climatic elements, especially temperature and rainfall regime, both in humid forests (Torres & Bandeira, 1985;Cancello et al, 2014) and in semiarid ecosystems (Moura et al, 2006;Araújo et al, 2010), yet the humid forest sites show higher rates of biomass and abundance of termites.…”
