Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

Skeletogenic Expression of Integrin Alpha, Talin and Npnt Genes and Npnt Role in Sea Urchin Skeletogenesis

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Three integrin alpha genes and the cytoskeletal adaptor talin are enriched in sea urchin skeletogenic cells during early skeletogenesis. The extracellular matrix protein nephronectin (Npnt) is expressed in the skeletogenic cells throughout skeletogenesis and supports normal skeletal growth, highlighting a potential role for cell–matrix interactions in ...

Climate and catchment influence the postglacial succession of three lakes in south‐central Baffin Island (Nunavut), Canada

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Understanding postglacial ontogeny in Arctic lakes helps contextualize modern‐day climatic change. We used sediment cores to characterize ecological succession in three south‐central Baffin Island lakes from deglaciation (c. 7–8k cal a BP) to present.

Scavenger dynamics at cervid carcasses in a chronic wasting disease endemic zone

open access: yesThe Journal of Wildlife Management, EarlyView.
This study quantifies scavenger species use of 20 deer carcasses in a chronic wasting disease endemic zone, including species‐specific time spent on carcasses and carcass materials consumed. We discuss the implications of our results for scavengers' roles in potential disease transmission dynamics.
