Abstract: 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 a...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...

Roger Saylor and Michel Ferrari (eds): Epistemology and Science Education: Understanding the Evolution vsntelligent Design Controversy
Download2012
Introduction: For decades the creationist movement has threatened the teaching of evolution in the United States, even in public schools. Similar worrisome trends have started in other Western countries. Beyond the major importance of reacting to attempts to undermine the proper teaching of...

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 behavior and present new observations on sponge activity in situ. We also...

Benthic marine habitats in Canada have been well-sampled since the annual groundfish survey commenced in 1970. However, trawl surveys cover only non-rocky sediments and many species collected are not identified to lower taxa, leaving large gaps in our understanding of benthic diversity. Sponges...

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...

Sycon coactum - transcriptome
2014-02-27
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...
