Invasive Amphisteginids conquer the Sicily Channel and knock on the door of the Western Mediterranean Sea

2018

This study reports an updated overview of the current distribution and establishment status of the invasive species Amphistegina lobifera Larsen, 1979 and of other non-indigenous foraminifera in the Sicily Channel. The dispersal of marine non-indigenous species (NIS) by human activities is redefining the biogeography of the oceans and is one aspect of global change. Understanding the role of NIS in altering the structure of marine communities requires accurate information on their temporal occurrence, spatial distribution and effect on native ecosystems. However many NIS, particularly those belonging to small-sized unicellular taxa, such as benthic foraminifera, are largely unrecognized and…

Contribution to the knowledge of Tunisian amphibians: notes on distribution, habitat features and breeding phenology

2009

In order to improve the knowledge on amphibian fauna in Tunisia, about 300 water bodies belonging to different habitat typologies were sampled during the period 2004-2008. At the sites where amphibians were observed, we recorded the UTM coordinates, the altitude, and the following environmental features: habitat typology, hydroperiod, electric conductivity, temperature, water turbidity, and macrophyte coverage. The presence of the seven species currently known with certainty for Tunisia has been confirmed: Pleurodeles nebulosus, Discoglossus pictus, Bufo bufo, B. mauritanicus, B. boulengeri, Hyla meridionalis and Pelophylax saharicus. Conversely, no evidence on the occurrence of Salamandra …

2022

Stenothoe bella Krapp-Schickel & Lo Brutto, 2015 and Stenothoe levantina Krapp-Schickel & Lo Brutto, 2015 are now available according to the International Code of Zoological Nomenclature (ICZN 1999, 2012). The present note serves to validate the names Stenothoe bella and Stenothoe levantina by fulfilling ICZN conditions for nomenclatural availability.

Diel feeding habits of juveniles of Mullus surmuletus (Linneo, 1758) in the lagoon of the Stagnone di Marsala (Western Sicily, Italy)

1999

Diet composition, feeding rhythm, gastric evacuation rate and daily ration were investigated in juvenile Mulhis surmuletus (Linneo, 1758). Fish were collected in the lagoon of the Stagnone di Marsala in western Sicily, in July 1995, during a 24 h sampling period. Copepoda, Polychaeta, Amphipoda and Tanaidacea were shown to be the most frequent prey items. The feeding index values showed two different daily feeding times. A unimodal trend in the daily rhythm of food consumption was derived, with a peak in feeding between 1200 and 2000 h. Gastric evacuation in juvenile M. surmuletus is best described by an exponential model, with a gastric evacuation rate R = 0.66 g h-1 (r = 0.88) (T = 24.45 …
