“…Stable isotope measurements of CH<span class="inline-formula">₄</span> suggest that hydrogenotrophic methanogenesis represents a dominant pathway for CH<span class="inline-formula">₄</span> production in the HZ of the river Moosach, while a relatively high abundance of a novel group of methanogenic archaea, the <i>Candidatus</i> “Methanomethyliales” (phylum <i>Candidatus</i> “Verstraetearchaeota”), indicate that CH<span class="inline-formula">₄</span> production through H<span class="inline-formula">₂</span>-dependent methylotrophic methanogenesis might also be an important CH<span class="inline-formula">₄</span> source. …”

Disparity, decimation and the Cambrian "explosion": comparison of early Cambrian and Present faunal communities with emphasis on velvet worms (Onychophora) by Julián Monge-Nájera, Xianguang Hou, José A Vargas

“…We conclude that (1) a mature ecological community structure was generalized during the Cambrian, and even biodiversity and equitability indices were surprisingly close to modern values; (2) the morphological diversity and geographic distribution of onychophorans indicate a significant pre-Cambrian evolutionary history which does not support the "explosion" hypothesis; (3) disparity among phyla was not as important as the explosion-decimation model predicts, but in the case of onychophorans, disparity within the phylum was greater than it is today and its reduction may have been associated with migration into the sediment when large predators evolved.…”
