Lake ecosystems are nowadays often subjected to multi-stressors, such as eutrophication, climate change, and fish manipulations, the effects of which can be difficult to disentangle, not least from the usual short-term limnological time-series that are available. However, multi-proxy paleoecological approaches may offer such opportunities, especially in the(More)
Basic biological information for a sublittoral population of the rock goby Gobius paganellus Linnaeus, 1758 is presented based on a 2-year study involving 1680 specimens. The length–weight relationship was given by TW = 0.0089 * TL3.163 (where TW= total weight in g; TL= total length in mm). Age at length data were inferred by modal analysis of the monthly(More)
Heavy metal concentration in a given locality depends upon its natural characteristics and level of anthropogenic pressure. Volcanic sites have a different heavy metal footprint from agriculture soils and both differ from urban centres. Different animal species absorb heavy metals differently according to their feeding behaviour and physiology. Depending on(More)
In this paper we wish to illustrate different perspectives used to create Multiple-Choice questions and we will show how we can improve these in the construction of math tests. As it is known, web technologies have a great influence on student’s behaviour. Based on an on-line project beginning at 2007 which has been contributing to help students on their(More)
Natural history collections from museums and private institutions can play an important role supporting decisions in biodiversity conservation. Seahorse populations have suffered a worldwide decline, while many areas remain data deficient including areas subjected to heavy commercial trading, such as the coasts of West Africa. In this work, seahorse(More)
Biological characterisation of the Santa Clara submarine tunnel in S. Miguel Island (Azores) is made. Spatial description of the cave is provided and zonation and stratification patterns of sessile epifauna are described. Profiles were based on sketches drawn in loco. Fauna census was conducted with non-destructive techniques: in loco observations(More)
