“…This suggests that over the short duration of our experiment, Roundup led to heavier earthworms that were less active at the surface, probably because there was abundant food in form of dead roots or AMF in the soil that precluded earthworms from foraging food from the surface. Other studies showed that earthworm biomass was unaffected by glyphosate-based herbicides for endogeic species48, whereas in temperate epigeic species3049 and tropical earthworms strong mass loss after glyphosate application was found50. Studies investigating effects of Roundup on soil dwelling endogeic earthworm species ( Aporrectodea caliginosa ) found no alteration of the energy status after acute exposure31.…”

Herbicides containing glyphosate are widely used in agriculture and private gardens, however, surprisingly little is known on potential side effects on non-target soil organisms. In a greenhouse experiment with white clover we investigated, to what extent a globally-used glyphosate herbicide affects interactions between essential soil organisms such as earthworms and arbuscular mycorrhizal fungi (AMF). We found that herbicides significantly decreased root mycorrhization, soil AMF spore biomass, vesicles and propagules. Herbicide application and earthworms increased soil hyphal biomass and tended to reduce soil water infiltration after a simulated heavy rainfall. Herbicide application in interaction with AMF led to slightly heavier but less active earthworms. Leaching of glyphosate after a simulated rainfall was substantial and altered by earthworms and AMF. These sizeable changes provide impetus for more general attention to side-effects of glyphosate-based herbicides on key soil organisms and their associated ecosystem services.

“…Os enquitreídeos são comuns em muitos solos, principalmente nos primeiros 0,05 m, e desempenham a função de decomposição (Cortet et al, 1999); o hábito deles de ingestão direta de solo pode ter aumentado sua exposição (ABNT, 2012). Ensaios com minhocas constataram aumento da possibilidade de alta ingestão do herbicida glifosato, em razão da alta adsorção desse com a argila do solo (García-Pérez et al, 2014). Estudando eisenia fetida, em contato com papel-filtro, Wang et al (2012) caracterizaram os herbicidas fluazifop-P-butyl e mesotrione como moderadamente tóxicos.…”

“…Com isso, altera-se o funcionamento do solo (Cortet et al, 1999), como os processos de decomposição vegetal (Hendrix e Parmelee, 1985), a manutenção da estrutura do solo, a transformação e a mineralização da matéria orgânica e o controle de organismos considerados pragas (Gill e Garg, 2014). Há autores que concluem que há efeitos negativos do uso de herbicidas sobre a estruturação da comunidade de invertebrados do solo, como colêmbolos (Haque et al, 2011), nematoides (Zhao et al, 2013), minhocas (García-Pérez et al, 2014) e diversos grupos de microrganismos (Crouzet et al, 2010;Camelo et al, 2011;Karpouzas et al, 2014;Darine et al, 2015).…”

rEsumoO controle químico de plantas daninhas é um método eficaz utilizado em florestas plantadas e em áreas de restauração florestal, favorecendo o desenvolvimento das mudas florestais e a redução dos custos de intervenção. Entretanto, se essa estratégia não for aplicada de maneira correta, pode-se tornar um potencial causador de impactos negativos aos organismos do solo e aos processos ecológicos que esses participam. avaliou-se o efeito do uso de herbicidas na biota do solo por meio da amostragem da comunidade da fauna edáfica e testes ecotoxicológicos de reprodução e sobrevivência de Folsomia candida e Enchytraeus crypticus, em área-alvo de restauração florestal recém-implantada. O delineamento experimental adotado foi de blocos casualizados com quatro tratamentos e cinco repetições. os tratamentos consistiram da aplicação dos herbicidas pós-emergentes mesotrione (0,4 l ha -1 ), fluazifop-P-butyl (1,0 L ha -1 ) e nicosulfuron (1,5 l ha -1 ), aplicados em área total nas parcelas, mais o controle (sem aplicação). na área de estudo, foram realizadas duas aplicações dos herbicidas com intervalos de seis meses, onde as parcelas foram correspondentes aos tratamentos em ambas as aplicações. Em cada parcela, foram realizadas quatro coletas de solo, sendo a primeira (coleta 1) seis dias antes da segunda aplicação dos herbicidas na área. as demais, após um (coleta 2), oito (coleta 3) e 22 dias (coleta 4) dessa mesma aplicação. a comunidade da fauna do solo foi avaliada por meio do método de funis de Berlese modificado, utilizando-se uma amostra de solo por parcela. Em laboratório, os indivíduos foram contados e identificados em grandes grupos. Os ensaios ecotoxicológicos de sobrevivência e reprodução de F. candida e E. crypticus foram realizados a Recebido para publicação em 15 de maio de 2015 e aprovado em 28 de julho de 2015.

“…Even at the highest concentrations of a glyphosate-based herbicide (GBH) (47 mg a.i.kg −1 ), Buch et al (2013) did not find any significant effect on mortality. Conversely, García-Pérez et al (2014) showed that GBH could have lethal impacts on P. corethrurus, as the application of GBH to coffee plantations thrice a year caused significant reduction in P. corethrurus density (167 and 353 ind.m −2 with and without herbicide, respectively) and biomass (23 and 45 g m −2 with and without herbicide, respectively). However, in another study under laboratory conditions by the same authors, earthworms exposed to a Coffea litter polluted by GBH produced the same number of cocoons as P. corethrurus fed with the unpolluted litter (García-pérez et al, 2016).…”

A B S T R A C TExotic peregrine earthworms are often considered to cause environmental harm and to have a negative impact on native species, but, as ecosystem engineers, they enhance soil physical properties. Pontoscolex corethrurus is by far the most studied morphospecies and is also the most widespread in tropical areas. The term of morphospecies is used in this review because P. corethrurus may in fact constitute a complex of cryptic species. This earthworm is found in a wide range of habitats, from apparently pristine to any kind of human-disturbed environment. This review synthesizes 265 studies describing the distribution, morphology, biological and ecological traits of this morphospecies, as well as its impacts on soil conditions and communities. We then discuss the characteristics necessary for this specific morphospecies to become a successful colonizer throughout the world and the positive and negative effects it can have on the ecosystems that it has invaded. We emphasize the lack of knowledge of P. corethrurus reproductive mode and ploidy level, of its population genetics, and of the potential existence of cryptic species. To finish, we highlight the fact that data on P. corethrurus interactions with non-earthworm soil macrofauna are scarce.
