The dynamics of covering behaviour in dominant echinoid populations from American and European west coasts

first_imgThe so-called ‘covering behaviour’ of echinoids is known to vary with habitat according to the types of covering items available, but the full extent of the role played by habitat characteristics in this behaviour is not known. Moreover, whether or not different species inhabiting similar environmental conditions and habitats also show similar patterns of this particular behaviour has yet to be investigated. In this study, two prominent west coast echinoid species, Paracentrotus lividus and Strongylocentrotus purpuratus, were examined with respect to covering behaviour and spatial organisation. Populations of both species are found in exposed intertidal zones, occupying boreholes within tidepools. Important similarities were found in the spatial organisation of both species’ populations, with lowest densities in upper shore pools. However, the size distributions of the two populations differed significantly; P. lividus within upper shore pools were significantly larger than those in mid or lower shore pools, whereas S. purpuratus on the lower shore were significantly larger than those at other shore heights. We found significant between-species variability in covering item use, although the number of covering items available at both sites was not significantly different. For example, greater densities of covering items were used by P. lividus than by S. purpuratus. We also found that the percent of echinoid surface area covered varied significantly in space for both species. These data emphasise the complex and multifaceted nature of covering behaviour, but most importantly, they also strongly suggest that habitat characteristics can only partly explain the extent of this behavioural variability amongst echinoid species.last_img read more

With an investment of two million euros, Hrvatsko Zagorje is opening up to business tourism

first_imgOne of the first small family hotels in Hrvatsko Zagorje, which has been named the best small continental hotel in Croatia for three years in a row, has made a unique step forward in the offer of continental tourism.The investment worth two million euros opens Villa Magdalena to the business tourism sector as well. Villa Magdalena is unique in that each accommodation unit is equipped with a jacuzzi with thermal water in the living room. Two conference halls are also a novelty, which has positioned this hotel as a desirable choice for various business arrangements. “We are aware that investments are the key to survival in an increasingly demanding market and a response to the needs of guests, which is where the idea of ​​expanding the hotel’s capacity came from. Zagorje has a huge tourist potential and I am sure that our example will encourage other investors to pay more attention and look for investment opportunities in our area.”, Said the owner of the Villa Magdalena hotel, Ivan Petrović, and added that the investment was financed with its own funds.Hotel Villa Magdalena is the first four-star hotel in Hrvatsko Zagorje and Krapinske Toplice opened in 2009. Last year, the hotel achieved an occupancy rate of 81 percent throughout the year and a total of 5.741 overnight stays in only nine accommodation units. For three years in a row (2012, 2013 and 2014) it was named the best small continental hotel in Croatia according to the choice of Tourist Flower – Quality for Croatia. “Investments are key to further strengthening the competitiveness of tourism in the Republic of Croatia, with investments in the hotel industry being of particular importance because this is a segment that characterizes year-round operations. According to the Tourism Development Strategy of the Republic of Croatia until 2020, the plan is to increase the share of hotels in the total accommodation structure, but also to strengthen the additional tourist offer throughout the year throughout the country, especially on the continent with great tourist potential. Therefore, hotels that offer additional facilities to tourists in addition to their classic offer, for example in the health tourism segment, are a strong element for the development of the quality of the overall tourist offer of Croatia, but also the destination in which they operate. Also, with its renovation, the hotel Villa Magdalena has the opportunity to position itself as a place for business meetings and conferences, which will contribute to the year-round offer of Zagorje and the continental part of Croatia in general.Said Tourism Minister Gary Cappelli.last_img read more
