Prvi nalazi dinoflagelata roda Dicroerisma (Actiniscales, Dinophyceae) na Sredozemnom moru
2011
This study is the first to describe and illustrate the dinoflagellate genus Dicroerisma in the Mediterranean Sea. Twenty individuals ascribed to Dicroerisma psilonereiella were encountered. The highest abundance (12 cells L-1) was recorded in the Balearic Sea at 50 m depth. Other specimens were found in subsurface waters (>75 m depth, with some records at 250 m depth) in the Ionian and Levantine Basin. These findings suggest that Dicroerisma is a widespread genus and its presence has gone unnoticed due to its small size, deep water distribution and misidentification with other gymnodinioid cells.
Effects of NIS on Mediterranean marine ecosystems: the case study of Egadi Island MPA (Sicily, Tyrrhenian Sea)
2018
Habitat modification and loss, climate change and the introduction of Non-Indigenous Species (NIS, i.e. organisms introduced outside of their natural, past or present, range and outside of their natural dispersal potential) are considered to be the main threats to Mediterranean marine biodiversity and natural ecosystem functioning. NIS may become invasive (IAS = Invasive Alien Species) and may have significant environmental, socio-economic and human health impacts. The Mediterranean Sea is one of the major hotspots for NIS introductions, with the total for these species having almost reached the 1,000 figure (equivalent to ca. 6% of the total flora and fauna). NIS are entering the Mediterra…
CHEMICAL INVESTIGATION OF THE INVASIVE ALGA CAULERPA TAXIFOLIA VAR. DISTICHOPHYLLA FROM SICILIAN COASTS
2018
Biological invasions by non-indigenous species have been widely recognized among the most important threats to the integrity of Mediterranean ecosystems, often resulting in huge economic and societal impacts. The success of non-indigenous macrophytes in the new range may be due to a variety of factors such as their vegetative reproductive strategy and synthesis of toxic compounds. These toxic compounds may influence native consumers by reducing their performance with negative implications for their overall grazing activity and, ultimately, for their ability to control the spread of the invasive algae in the new area. In particular, the invasive algae Caulerpa taxifolia (Vahl) C. Agardh (Ct)…
