| ENCONTRO LATINO AMERICANO DE ECOLOGIA E TAXONOMIA DE OLIGOQUETAS, 5., 2015, Curitiba.. |
| O solo abriga e sustenta uma ampla gama de organismos, incluindo engenheiros do ecossistema que mundialmente representam milhares de espécies importantes para o funcionamento edáfico. Os engenheiros edáficos incluem as minhocas, as formigas e os cupins, além de algumas espécies de milipéias e besouros que modificam a estrutura do solo e a distribuição de recursos (especialmente matéria orgânica) no solo para outros organismos, incluindo as raízes das plantas. Esses animais afetam diversos serviços ambientais considerados de grande importância para produção agrícola e florestal sustentável, como a produção vegetal, a emissão de gases de efeito estufa, o controle da erosão e de pragas e doenças das plantas e dos animais, a retenção e infiltração da água no... |

| On Chichijima, one of the Ogasawara (Bonin) Islands located in the Western Pacific Ocean, land snails have declined, the suggested cause being predation pressure by an invasive flatworm (Platydemus manokwari). Soil fauna were investigated in areas where the snail survives, and where it has become extinct. Much of the fauna, dominated by introduced earthworms and ants, was undiminished, however, one undescribed but endemic carabid (Badister sp.), which selectively feeds on land snails, was absent in snail-extinct areas. The invasive flatworm P. manokwari has been reported to feed also on the carcasses of earthworms, as well as on live snails, and is therefore expected to occur in most parts of Chichijima Island. Among other groups, the density of isopods... |

| The biodiversity of soil communities remains very poorly known and understood. Soil biological sciences are strongly affected by the taxonomic crisis, and most groups of animals in that biota suffer from a strong taxonomic impediment. The objective of this work was to investigate how DNA barcoding - a novel method using a microgenomic tag for species identification and discrimination - permits better evaluation of the taxonomy of soil biota. A total of 1,152 barcode sequences were analyzed for two major groups of animals, collembolans and earthworms, which presented broad taxonomic and geographic sampling. Besides strongly reflecting the taxonomic impediment for both groups, with a large number of species-level divergent lineages remaining unnamed so far,... |

| The objective of this work was to evaluate the effect of organic and conventional coffee crops on biomass, population density and diversity of earthworms, in Lerroville, district of Londrina County, Paraná state, Brazil. Earthworm communities were sampled in three areas with organic coffee cultivation (CO1, CO2 and CO3), two with conventional coffee (CC1 and CC2), and a native forest fragment (MT). The soil of the areas CO1, CC1, and MT was classified as Nitossolo Vermelho (Rhodic Kandiudox), while CO2, CO3, and CC2 were on Latossolo Vermelho (Rhodic Hapludox). Eight samples were taken in each area on two occasions, winter and summer, using the Tropical Soil Biology and Fertility (TSBF) method in the 0-20 cm soil layer. The earthworms were handsorted and... |

| Abstract Freshwater oligochaetes have been studied over the years in a wide range of habitats around the world. To analyse the data published about freshwater oligochaetes in the 31 year period between 1985 and 2015, we searched for documents in the ISI Web of Science, Scopus and SciELO databases. A total of 979 works were evaluated from 184 periodicals. The United States is the country with the most publications about aquatic oligochaetes, followed by France, Germany and Italy. Works related to the ecology and ecotoxicology of these organisms are most abundant. Studies carried out in the laboratory are most frequent, consisting of investigations involving bioassays, morphology, genetics and molecular biology. The results also show that spring, cave water... |

| Seven species of Tubificidae are recorded from the Canary Islands, viz. Heterodrilus amplus n. sp., Coralliodrilus leviatriatus Erséus, 1979, Limnodriloides agnes Hrabĕ, 1967, L. janstocki n. sp., Aktedrilus cuneus Erséus, 1984, A. parvithecatus (Erséus, 1978), and Tubifex tubifex (Müller, 1774); the two latter taxa are reported also from the Cabo Verde Islands. All taxa except T. tubifex are marine and there is no evidence of endemism in the freshwater oligochaete fauna of these islands. Heterodritus amplus has short, spindle-shaped, heavily muscular atria; they are morphologically unique within the genus. Limnodriloides janstocki has modified spermathecal setae; it is distinguished from similar species by its long atrial ducts and deep, elaborate... |

| We analysed samples of Sparganophilus taken at the corners of its distribution area in Europe (UK, Germany and Italy). No mitochondrial genetic divergence within and amongst them was found, neither in COI nor in 16S. Further, the COI haplotype was also identical to two sequences from Ontario, Canada in the Barcoding of Life Data System (BOLD) database. Our European COI and 16S sequences showed only minimal differentiation (only 1 or 2 substitutions) from specimens newly collected in Illinois and Washington states (USA), as well as from a COI haplotype from Tennessee (USA) in BOLD. An additional COI haplotype from Illinois (found in BOLD) is 2.1% different from the other haplotypes but clearly belongs to the same lineage of Sparganophilus. This... |

| Oligochaete wormen komen vooral in zoet water voor. Maar in brak water en zelfs in de volle zee komen enkele soorten voor. Bij onderzoek naar marien benthos werden deze dieren traditioneel niet tot op soort gedetermineerd, omdat ze klein en lastig te determineren zijn. Ze zijn echter niet veel lastiger dan de nauw verwante Polychaeta, die ook hele kleine vertegenwoordigers kennen. In dit artikel wordt een overzicht gegeven van de 32 soorten die nu uit het zoute water in ons land bekend zijn, waarvan er hier zes als nieuw voor de Nederlandse fauna gepresenteerd worden. De vondst van Heterodrilus subtilis in de Noordzee is zeer bijzonder, omdat deze soort verder alleen bekend is van het typemateriaal, dat ongeveer honderd jaar geleden in de Golf van Napels... |

| The aim of this study was to evaluate abundance, biomass and diversity of earthworms in the southern coast region of the Mata Atlântica biodiversity hotspot. A total of 51 study sites in pastures, banana monocultures, mixed agroforestry systems, secondary forests in succession and old-growth forests near the coast of Paraná, Brazil, were evaluated. Each site was sampled once. Species richness of the earthworms was generally low and varied little between sites. At all sites except for one, the peregrine species Pontoscolex corethrurus (Glossoscolecidae) strongly dominated. Three other peregrine species, Amynthas corticis, Amynthas gracilis (Megascolecidae) and Ocnerodrilus occidentalis (Ocnerodrilidae), were frequent in moist sites. No autochthonous species... |

| Spermatogenesis and the spermatozoon ultrastructure follow a common pattern in terrestrial oligochaetes. However, many of their characteristics are distinctive of each species and they are of great importance for phylogenetic and taxonomic studies. Germinal cells were studied through conventional electronic microscope techniques in order to go deep on spermatogenesis, especially on the mature spermatozoon ultrastructure of Eisenia foetida. Spermatogenesis occurs in seminal vesicles and follows a pattern comparable to that of some other oligachaetes species. Spermatozoon ultrastructural details revealed that it is a filiform cell, with the acrosome placed in anterior position, followed by the nucleus, the midpiece and the tail which flagellum has a 9+2... |
