“…On the other hand, Schmelz et al (2013) reported that enchytraeids occur worldwide in all soils with sufficient moisture, oxygen and nutrient supply, with densities in tropical regions comparable to those in temperate regions, suggesting that enchytraeids may be equally important for soil processes in both tropical and temperate regions (Schmelz et al, 2013). This discrepancy may at least partly be due to the fact that knowledge on their diversity and functioning in the tropics is not so well developed, mainly due to their small size, the difficulties of identification, and the general ignorance of this family (Brown et al, 2013;Schmelz et al, 2013). Although enchytraeid ecology and ecotoxicology is clearly biased toward studies in European temperate conditions, good examples of their use as test organisms and bioindicators are also present in tropical environments (e.g.…”

“…As also discussed above, very few standardized ecotoxicological tests have been performed assessing pesticide toxicity to tropical indigenous soil invertebrates (Brown et al, 2013;Garcia et al, 2011;Niemeyer et al, 2017;Niva et al, 2016). Most soil ecotoxicity studies, even when conducted in tropical areas, have generally been conducted using a series of invertebrate species originally found in temperate environments (Niemeyer et al, 2017;Römbke et al, 2008).…”

“…Allows determining biodiversity and facilitates the estimation of potential impacts on soil functioning and management variables, total earthworm biomass and density are easier to determine and were considered by Doube & Schmidt (1997) as more stable (less variable) than data on species in studies using earthworms as environmental bioindicators. However, given the large number of native and endemic species present in Brazilian soils (Brown et al, 2013), it is important to obtain data on these species and any preferences they might have for particular soil and environmental conditions, in order to enhance conservation and management efforts. The identification of earthworm species requires expertise, and, in many cases, proper identification is only possible by a taxonomist, although there are a few specialists in Brazil and elsewhere who can also identify Brazilian earthworm species.…”

Earthworms are often related to fertile soils and are also frequently used as environmental quality indicators. However, to optimize their use as bioindicators, earthworm populations must be evaluated together with the environmental and anthropogenic variables regulating their communities. This review sought to identify the earthworm-sampling, soil chemical and physical, and environmental and anthropogenic attributes evaluated in 124 published studies that quantified earthworm abundance (>7,300 samples) in 765 sites with different types of climate, soils, land use, and management systems in Brazil. Soil chemical and physical attributes (except pH) were less reported (≤50% of studies) than other environmental variables such as sampling date, altitude, temperature, precipitation, climate and soil type, and land use (>50% of studies). Earthworms were rarely identified (24%) and few studies (31%) measured their biomass, although most provided adequate information on sampling protocol. Based on their importance in regulating earthworm populations, a set of variables is proposed to be evaluated when studying earthworm communities and other macrofauna groups. This should help guide future studies on earthworms in Brazil and other countries, optimize data collection and replicability, allow comparisons between different studies, and promote the use of earthworms as soil quality bioindicators.

“…According to Brown et al , more than 1100 species of terrestrial oligochaetes are found in Latin America, but only a few of them are candidate species for standardized tests. Some studies show that Pontoscolex corethurus (Müller, 1857), an endogeic earthworm commonly found in Neotropics and a species with a widespread distribution in Brazil, is a good candidate for assessing the toxicity of tropical soils (Table ).…”

Soils from some Latin American countries support the highest biodiversity levels on the planet and simultaneously have some of the most serious environmental impacts attributed to both historical and current agricultural practices and industrial activities. Soil contamination has resulted from intensive use of pesticides, extensive mining and other industrial activities, and uncontrolled management of waste within inappropriate regulatory frameworks. The present study presents an overview of the scientific research on soil ecotoxicology conducted in Latin America, summarizing the recent advances and highlighting the needs for further refinements in this research field. Most of the contributions to the scientific literature have been from Brazil. The most investigated issue is the ecotoxicity of pesticides and earthworms, which were the organisms most frequently used as test species. Needs identified by Latin American researchers include methods and procedures for: 1) identifying and collecting natural soils to be used as reference test-substrates in tests, 2) identifying and discerning the range of sensitivities of native test species to soil contaminants, 3) developing environmental guidelines applicable to tropical/subtropical conditions, and 4) developing methods and procedures for higher tier testing for full development and implementation of environmental risk assessment schemes. The protection of Latin American soils, including provision of goods and services, is currently framed in legislation and other regulations, but implementation requires significant improvement and additional training programs.
