Phylogenomic analyses of Crassiclitellata support major Northern and Southern Hemisphere clades and a Pangaean origin for earthworms

BMC Evolutionary Biology, 2017
Background Earthworms (Crassiclitellata) are a diverse group of annelids of substantial ecological and economic importance. Earthworms are primarily terrestrial infaunal animals, and as such are probably rather poor natural dispersers.

Climate Warming Drives Northward Contraction and Genetic erosion in a Cold‐Adapted Soil Worm Species

Diversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim Climate‐driven range fluctuations since the Pleistocene have repeatedly reshaped species distributions and population structures, with lasting consequences for genetic diversity. Contemporary warming causes similar pressures, yet most work emphasizes range shifts and gives less attention to genetic outcomes.

Global Expansion of Ponto‐Caspian Aquatic Invaders: Drivers, Trends and Taxonomic Biases in a Changing World

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Biological invasions pose major threats to ecosystems, with aquatic habitats particularly vulnerable due to high connectivity and biodiversity. The Ponto‐Caspian region is widely recognised as a major source of highly invasive non‐native aquatic species, yet a global synthesis of their spatial, taxonomic and temporal invasion patterns has been

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

Zoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,
