Sponges (Porifera) are abundant in most marine and freshwater ecosystems, and as suspension feeders they play a crucial role in filtering the water column. Their active pumping enables them to filter up to 900 times their body volume of water per hour, recycling nutrients and coupling the benthic...

SUMMARY Several inorganic compounds of nitrogen (N) and phosphorus (P) are key to ocean ecology because, among other effects, they sustain primary production. After discovering in the 1980s that sponges can be both source and sink of such nutrients, much has been learned, including that fluxes...

Supplementary Files for: Sponge behaviour and the chemical basis of responses: a post-genomic view

Sponges perceive and respond to a range of stimuli. How they do this is still difficult to pin down despite now having transcriptomes and genomes of an array of species. Here we evaluate the current understanding of sponge behaviour and present new observations on sponge activity in situ. We also...

Sycon coactum - transcriptome

Sponges (Porifera) are among the earliest evolving metazoans. Their filter-feeding body plan based on choanocyte chambers organized into a complex aquiferous system is so unique among metazoans that it either reflects an early divergence from other animals prior to the evolution of features such...

Sponges link the microbial loop with benthic communities by feeding on bacteria. Glass sponge reefs on the continental shelf of western Canada have extremely high grazing rates, consuming seven times more particulate carbon than can be supplied by vertical flux alone. Unlike many sponges, the...

Uptake of waterborne selenite, and its toxic effects, in the water flea (Daphnia magna), Westslope cutthroat trout (Oncorhynchus clarkii lewisi) and rainbow trout (Oncorhynchus mykiss)
DownloadSpring 2024
Selenium is an essential element, playing an important role in many physiological processes. However, it possesses a narrow margin between essentiality and toxicity. In aquatic systems, selenium is increasingly identified as a trace element of major concern with levels exceeding regulatory...

Windsor Reid, Pamela J., Matveev, Eugueni, McClymont, Alexandra, Posfai, Dora, Hill, April L., Leys, Sally P.
Background: The Wnt signaling pathway is uniquely metazoan and used in many processes during development, including the formation of polarity and body axes. In sponges, one of the earliest diverging animal groups, Wnt pathway genes have diverse expression patterns in different groups including...
