Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]
, 2013 In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.

No Mate, No Problem: Molecular Mechanisms Involved in Parthenogenesis in the Cosmopolitan Earthworm Aporrectodea trapezoides (Annelida, Clitellata). [PDF]
Mol EcolABSTRACT Approximately, 40% of earthworm species can reproduce by parthenogenesis. This is the case for the cosmopolitan species, Aporrectodea trapezoides, although sexual forms have been described sporadically. We analyse the genotypes and microbiomes of 30 individuals from four localities where both forms appear in order to understand the ...

Earthworms (Oligochaeta: Lumbricidae) of Interior Alaska
Biodiversity Data Journal, 2018 Earthworms in the family Lumbricidae in Alaska, which are known from coastal regions, primarily in south-central and south-eastern Alaska, are thought to be entirely non-native and have been shown to negatively impact previously earthworm-free ecosystems

Metabarcoding Close to Home: Songbird Nests as eDNA Aggregators for Trophic Ecology and Biodiversity Studies. [PDF]
Ecol EvolWe present a novel method for extracting eDNA from whole bird nests and a LNA blocking oligonucleotide designed to reduce metabarcoding reads from nest building sparrows. Metabarcoding of 22 nests from a montane sagebrush steppe ecosystem detected 126 species, primarily insects, including putative diet items, ectoparasites, and confirmed nest predators.

A histidine-rich extension of the mitochondrial F<sub>0</sub> subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria. [PDF]
FEBS LettThe glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results
