Devastating Rio Doce mining disaster sends shockwaves through earthworm populations

open access: yesJournal of Environmental Quality, EarlyView.
Abstract The Fundão dam breach is considered one of the most severe environmental mining disasters globally, causing widespread changes to the soils of the Rio Doce watershed, one of Brazil's most important catchments. Given the ecological importance of earthworms to soil structure and dynamics, we investigated the richness, abundance, and biomass of ...

Gene and Genome Duplication in Spiders

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In chelicerates whole genome duplications (WGDs) were identified in distinct groups. While there is evidence that Xiphosurans/horseshoe crabs had three rounds of WGD and arachnopulmonates (e.g. spiders and scorpions) had one WGD, in many other arachnid groups no WGD was identified.

Reconstructing the late Pleistocene glacial history of the Cairngorm Mountains, Scotland, using paired cosmogenic 10Be and 14C

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Chronologic and geomorphic evidence of past glaciations is largely recorded in areas at relatively low elevation and/or landscapes defined by high glacial erosion. As a result, data from areas that did not experience significant glacial erosion and the highest elevation locations are lacking from reconstructions of past ice masses.

The article sets out to explore the idea that we are witnessing the emergence of a host of initiatives on both sides of the Atlantic, in the North as well as in the South, and that these Atlantic communitiescould eventually converge toward the formation ...
