The role of cell replacement in benthic–pelagic coupling by suspension feeders [PDF]
Royal Society Open Science, 2016 Benthic–pelagic coupling through suspension feeders and their detrital pathways is integral to carbon transport in oceans. In food-poor ecosystems however, a novel mechanism of carbon recycling has been proposed that involves direct uptake of dissolved ...

The early expansion and evolutionary dynamics of POU class genes. [PDF]
, 2014 The POU genes represent a diverse class of animal-specific transcription factors that play important roles in neurogenesis, pluripotency, and cell-type specification. Although previous attempts have been made to reconstruct the evolution of the POU class,

Gigantism in unique biogenic magnetite at the Paleocene-Eocene Thermal Maximum [PDF]
, 2008 We report the discovery of exceptionally large biogenic magnetite crystals in clay-rich sediments spanning the Paleocene-Eocene Thermal Maximum (PETM) in a borehole at Ancora, New Jersey. Aside from previously-described abundant bacterial magnetofossils,

Host population genetics and biogeography structure the microbiome of the sponge Cliona delitrix
Ecology and Evolution, 2020 Sponges occur across diverse marine biomes and host internal microbial communities that can provide critical ecological functions. While strong patterns of host specificity have been observed consistently in sponge microbiomes, the precise ecological ...
