Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, distribution, and the threats affecting them. We compiled global dataset sampled earthworm communities from 6928 sites in 57 countries as basis for predicting patterns abundance, biomass. found that local species richness abundance typically peaked at higher latitudes, displaying opposite to those observed aboveground organisms. high dissimilarity across...
Three new species of the earthworm genus Zapatadrilus are described from Tamaulipas, Mexico: aurelius sp. nov., huastecus and montezumensis nov. Delimitation was supported by morphological molecular (genetic distances) evidence. Diagnostic characters three include: tubulo-racemose prostates in segments 18 20, penial setae absent, typhlosole present intestine beginning 17/18. Z. is separated its metandric condition, last hearts 13 shape spermathecae patterns genital markings.
A new acanthodriline earthworm species, Lavellodrilus notosetosus sp. nov., is described from tropical rain forests of southern Mexico. The species placed within the genus by presence mesial spermathecal pores. It separated other dorsal location setae cd in most body, last hearts segment 13, first intestinal 20 and genital 12. preliminary morphological revision all genera Acanthodrilinae was undertaken order to: i) evaluate if pores justify status Lavellodrilus, ii) determine how common...
Two earthworm species from central Mexico are described: Protozapotecia acaxetlensis sp. nov. and oya-metlensis Delimitation of was supported by morphological molecular evidence. The two new differ the other position prostates in segments 18 20. This characteristic relates them to genus Diplocardia, which they presence gizzards separated a muscular septum (Protozapotecia), instead fused as one, thin membranous intersegment 5/6 (Diplocardia).
Three new Acanthodrilinae species from the states of Oaxaca, Tabasco and Chiapas in southern Mexico are described, Diplotrema oaxacana sp. nov., tabascensis kaxyebensis respectively. D. nov. is characterized by presence genital setae segments 8 9, a spermathecal ampulla transversally connected to duct paired seminal vesicles 11 12. separated all segment 16. The singleton single pair 12, particular arrangement duct-ampulla-diverticulum connections. It discussed that neotropical lineage does...
Abstract Aim Macroinvertebrates comprise a highly diverse set of taxa with great potential as indicators soil quality. Communities were sampled at 3,694 sites distributed world‐wide. We aimed to analyse the patterns abundance, composition and network characteristics their relationships latitude, mean annual temperature rainfall, land cover, texture agricultural practices. Location Sites are in 41 countries, ranging from 55° S 57° N 0 4,000 m elevation, rainfall 500 >3,000 mm temperatures...
Abstract Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial functions and services. Little is known about their diversity distribution at large spatial scales, despite the availability considerable amounts local-scale data. Earthworm data, obtained from primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, properties. Datasets required, minimum, to include...
Abstract The structural framework of soil mediates all processes, at relevant scales. spatio‐temporal heterogeneity prevalent in most soils underpins the majority biological diversity soil, providing refuge sites for prey against predator, flow paths biota to move, or be moved, and localized pools substrate multiply. Just as importantly, play a crucial role mediating structure: bacteria fungi aggregate stabilize structure small scales (μm–cm) earthworms termites create larger‐scale...
Prof. Pietro Omodeo (University of Siena, Italy), the world-renowned earthworm taxonomist and evolutionary biologist, was born in Cefalù, Sicily, Italy on 27th September, 1919. He celebrates his 100th birthday 2019 members international community taxonomists salute him with Petroscolex centenarius gen. et sp. nov., a new megadrile taxon discovered 1991 by but which has not been formally described until now. The many important contributions to oligochaetological research are briefly mentioned.
