Centropages typicus (Crustacea, Copepoda) reacts to volatile compounds produced by planktonic algae

Volatile organic compounds (VOCs) may play the role of infochemicals and trigger chemotaxis and ecologically relevant responses in freshwater and marine invertebrates. Aquatic grazers use these signals as chemical cues to trace the presence of their food or to detect their predators. 260 more words

Assessing the state of pteropod shells and ocean acidification in Washington marine waters

The relationship between pteropod shell dissolution and waters undersaturated with aragonite has been well documented (Bednarsek et al 2012). Low aragonite saturation levels decrease the availability of carbonate ions in the water column, causing aragonite to dissolve out of pteropod shell structures. 195 more words

February 27 - In situ evidence of zooplankton migration in response to solar radiation

While it has been studied that copepods can sense and avoid harmful UV radiation through both horizontal and vertical migration, this study is one of the first to look at the short term daily response of zooplankton by radiation changes under sunny and cloudy conditions.   186 more words

Ocean acidification elicits different energetic responses in an Arctic and a boreal population of the copepod Pseudocalanus acuspes

Anthropogenic emissions cause the global CO2 partial pressure (pCO2) to increase, and atmospheric models predict a pCO2 of ~1,000 µatm by the year 2100. About one-third of emitted CO2 is absorbed by the world’s oceans, causing a decrease in ocean pH. 205 more words

My Night as a Diving Disney Princess

A few nights ago, I was as close as I think I will ever be to feeling like a Disney princess. Better yet, I felt like a much needed version of a Disney princess: a scuba diving one. 519 more words

Congratulations dr Falko Buschke & dr Tom Pinceel

After just three years, Falko Buschke‘s Erasmus Mundus PhD fellowship came to an end. Just months later he succesfully defended his PhD thesis. Initially drawn to Belgium with the prospect of doing a thesis on community dynamics with a lot of empirical work, Falko soon settled into a different niche. 301 more words
