The experiment on Ellisolandia reef terminates this week. The reef and its fauna were exposed to multiple stressors (pH and temperature) expected for 2100 for three months. Effects on reef-forming algae and its associated fauna will be investigated in the next months, in collaboration with the Department of Earth and Environmental Sciences of the University of Pavia.

Preliminary results will be presented at the next MARES Conference in Olhao, Portugal (1-5 February 2016)!

“Bioconstructors and climate change: from individuals to ecosystems” session- NEXT ASLO CONFERENCE

Abstract submission is now OPEN for “Bioconstructors and climate change: from individual to ecosystem ” session that will be held at the 2016 Ocean Science Meeting in New Orleans, Louisiana, on 21-26 February.
Abstract submission deadline: 23 September, 11:59 p.m. EDT
Information about this session are available at:

Marie Skłodowska-Curie Individual Fellowship at MedClimaLizers Lab (ENEA)

MS-C Individual Fellowship at MedClimaLizers Lab (ENEA) for international young researchers!

We are looking for a candidate with experience in organism rearing, marine aquaria, and experimental systems. Biological and ecological knowledge on benthic organisms, preferably calcifiers, is required. Since the laboratory will host Master and PhD students, as well as visiting researchers, we are looking for a candidate with good attitudes and able to work in team.

Dead line: 20 June 2015

For Expression of Interest: medclimalizers at gmail.com

The goal of MSC Individual Fellowship is to enhance the creative and innovative potential of experienced researchers wishing to diversify their individual competence in terms of skill acquisition at multi- or interdisciplinary level through advanced training, international and intersectoral mobility.

New paper on the effect of thermal stress on Ellisolandia elongata

In press on Marine Environmental Research

Effects of thermal stress on the growth of an intertidal population of Ellisolandia elongata (Rhodophyta) from N–W Mediterranean Sea

The first long term experiment (6 months) on Ellisolandia elongata under controlled conditions. The species revealed a potential ability to cope with seawater temperature changes expected for a future Mediterranean Sea (2100). This study highlights the importance and complexity of the organism as framework builder and Mediterranean marine biodiversity promoter.

Morphological plasticity in a calcifying modular organism: evidence from an in situ transplant experiment in a natural CO2 vent system

Understanding is currently limited of the biological processes underlying the responses of modular organisms to climate change and the potential to adapt through morphological plasticity related to their modularity. Here, Lombardi and coauthors investigate the effects of ocean acidification and seawater warming on the growth, life history and morphological plasticity in the modular bryozoan Calpensia nobilis using transplantation experiments in a shallow Mediterranean volcanic CO2 vents system that simulates pH values expected for the year 2100. Growth models describing colony development under different environmental scenarios suggest that stressed colonies of C. nobilis reallocate metabolic energy to the consolidation and strengthening of existing zooids. This is interpreted as a change in life-history strategy to support persistence under unfavourable environmental conditions. Changes in the skeletal morphology of zooids evident in C. nobilis during short-time exposure experiments reveal morphological plasticity that may indicate a potential to adapt to the more acidic Mediterranean predicted for the future.
