Moving Toward a Strategy for Addressing Climate Displacement of Marine Resources: A Proof-of-Concept
Realistic predictions of climate change effects on natural resources are central to adaptation policies that try to reduce these impacts. However, most current forecasting approaches do not incorporate species-specific, process-based biological information, which limits their ability to inform actionable strategies. Mechanistic approaches, incorporating quantitative information on functional traits, can potentially predict species- and population-specific responses that result from the cumulative impacts of small-scale processes acting at the organismal level, and can be used to infer population-level dynamics and inform natural resources management. Here we present a proof-of-concept study…
Investigationes on population dynamics and mortality of Phyllocnistis citrella in western Sicily (Italy)
Population dynamics and mortality of P. citrella, and its natural enemies with parasitism levels in two different citrus orchards, sprayed and unsprayed, were investigated. The effect of host density on percentage parasitism and mortality was calculated by regression analyses. In both sites, over the 3-years period from 2002 to 2004, P. citrella was detected during the summer months and it was not found during the first flush. Population levels were low, never exceeding 3.0/leaf. P. citrella began to increase from June in 2002-2003 and from July in 2004. The monthly percentage parasitism of P. citrella in sprayed orchard fluctuated from 0 to 19%, while in unsprayed from 0 to 30%. High morta…

Functional trait-based layers - an aquaculture siting tool for the Mediterranean Sea
Abstract Aquaculture, the current fastest-growing food sector, is one of the major opportunities that could be reaped to cope with the increased demand for proteins from the sea and simultaneously generate economic growth while ensuring sustainable use of natural resources. The number of tools and approaches suggested to promote the selection of suitable areas - focusing mostly on the management of potential conflicting uses at sea - is rapidly increasing. However, to date, there is a lack of information regarding spatial planning according to a trait-based approach encompassing the functional and biological data of farmed species; a gap that may lead to selecting unsuitable areas for farmi…
Critical phenomena originating magmatic rocks in western Sicily.
The behaviour of a model magma in the vicinity of a critical region is in agreement with results of studies of structures in the melt in basaltic rocks from Sicily. The behaviour of ionic-non ionic fluid mixtures simulating a magma has been analysed in the light of results obtained recently with simple statistical mechanical approximations. It is suggested that the Sicilian magma is to be considered as an extremely rare natural example of two immiscible liquids having almost consolute composition.
