Ouch! That hurts! Sensitivity In Sponges By Michaela Rohrbough

A week ago in lab I got to look over Leucilla nuttingi, one of the few calcareous sponges present off the coast of California. Calcareous sponges differ from other types of sponges in that their structural elements, known as spicules, are made of calcium carbonate instead of the more common silicon dioxide. 678 kata lagi

Scrub-A-Dub-Dub: What makes a good bath sponge? By Brittany Cunningham

Today in invertebrate biology lab we studied the spicules of both calcareous and siliceous sponges. Sponges are actually animals in the phylum Porifera and come in a variety of shapes, colors and sizes. 864 kata lagi

Impact of high pCO2 and warmer temperatures on the process of silica biomineralization in the sponge Mycale grandis

Siliceous sponges have survived pre-historical mass extinction events caused by ocean acidification and recent studies suggest that siliceous sponges will continue to resist predicted increases in ocean acidity. 238 kata lagi

UPDATE: Sponges Back on Top

Or should that be bottom? Back in July I wrote an article here about comb jellies and the origins of complex animals. There is currently a debate raging in zoological circles about whether sponges or comb jellies are actually the most primitive form of animal life on our planet and in July a new genomic study had just been published which suggested the title should go to the jellies. 973 kata lagi

Big Debates

Climate change stressors destabilize the microbiome of the Caribbean barrel sponge, Xestospongia muta

The effect of climate change, both thermal stress and ocean acidification, on coral reefs is of increasing concern with the effects on calcification at the organismal level, and changes in the ratio of accretion to erosion on larger spatial scales of particular interest. 204 kata lagi

Sponge erosion under acidification and warming scenarios: differential impacts on living and dead coral

Ocean acidification will disproportionately impact the growth of calcifying organisms in coral reef ecosystems. Simultaneously, sponge bioerosion rates have been shown to increase as seawater pH decreases. 239 kata lagi
