Abstract. The long-term monitoring of basic hydrological parameters (temperature and salinity), collected as time series with adequate temporal resolution (i.e. with a sampling interval allowing the resolution of all important timescales) in key places of the Mediterranean Sea (straits and channels, zones of dense water formation, deep parts of the basins), constitute a priority in the context of global changes. This led CIESM (The Mediterranean Science Commission) to support, since 2002, the HYDROCHANGES programme (http//www.ciesm.org/marine/programs/hydrochanges.htm), a network of autonomous conductivity, temperature, and depth (CTD) sensors, deployed on mainly short and easily manageable subsurface moorings, within the core of a certain water mass. The HYDROCHANGES strategy is twofold and develops on different scales. To get information about long-term changes of hydrological characteristics, long time series are needed. But before these series are long enough they allow the detection of links between them at shorter timescales that may provide extremely valuable information about the functioning of the Mediterranean Sea. The aim of this paper is to present the history of the programme and the current set-up of the network (monitored sites, involved groups) as well as to provide for the first time an overview of all the time series collected under the HYDROCHANGES umbrella, discussing the results obtained thanks to the programme.

Space Competition

The competition for space among fluorescent and nonfluorescent Anemonia species was monitored in the Mediterranean Sea in order to see whether the fluorescent species A. sulcata var. smaragdina was a better competitor in shallow water habitats. Over a period of 11 years, A. sulcata var. smaragdina convincingly out competed the nonfluorescent A. rustica. We thereby found support for the notion that the GFP-like pigments may increase competitive ability in anthozoans.

Demographic studies are fundamental in population ecology, as well as in conservation biology and wildlife management. However, few methods are available to determine the exact age of animals. Mark-recapture is usually the main method to study demography, but this approach is highly time-consuming and needs long-term monitoring. For species for which recapture is not feasible, this method is not valid. However, in vertebrates with indeterminate growth, such as fish, amphibians, and reptiles, skeletochronology is a method that allows age to be estimated from a bone. Nevertheless, studies of skeletochronology frequently involve the death of the animal to obtain the bone. In the present study, we test the reliability of phalanx skeletochronology, comparing the readings from the most commonly used bones in reptile skeletochronology (femur and humerus) with the age estimated from phalanges. Our results show phalanx skeletochronology to be a reliable method for estimating age in lizards without killing them. Cross-section readings from all bones studied presented a high correlation and repeatability, regardless of the phalanx chosen. These findings imply that, to apply skeletochronology, phalanges must be used instead of other bones that mean the death of the animal, and the killing of lizards for skeletochronology studies is no longer justified. This alternative is especially relevant for endangered species, considering that obtaining a representative sample usually requires a considerable number of individuals.
