“…Crete, as most of the other Greek islands, has undergone intensive human influence (at least 8000 years, Legakis et al 1993;Poulakakis et al 2015). The present population of approximately 500,000 is mainly active in agriculture and tourism.…”

Defining biodiversity conservation goals requires representative and reliable data. However, data collected with the use of different methods can lead to divergent conclusions. Regardless of the high level of biodiversity of Mediterranean habitats, very little attention was paid in developing methods allowing rapid and scalable estimation of their richness. This study aims to recognize and explain the differences in performance of two methods: pitfall traps (PTM) and a complementary method based on hand collecting (HCM), in surveys of ants in the Mediterranean. We compared the results of applying both methods in three habitats in relation to a-, b-, and c-diversity, and functional traits of species, i.e. Webber's length (WL), nesting preferences, and evolutionary origin. Mean species number per HCM was significantly higher than per PTM sample. Spatial species turnover of HCM samples was higher than in PTM ones. However, assemblage dispersion did not differ. HCM detected a higher number of species and genera. WL differed significantly between HCM and PTM, and HCM recorded significantly more species in individual nesting guilds, regardless of considered habitat. HCM detected higher diversity of functional characteristic combinations of species. PTM detected fewer species with slightly larger body size and is useful in recognizing spatial species diversity patterns. HCM detected a higher number of species and produced more comprehensive results in identifying the functional diversity of ant assemblages. In conclusion, an integrated approach, described here as HCM, appears to be more suitable for heterogeneous Mediterranean habitats, especially when a survey aims at a-, b-, and c-diversity assessments.Keywords Ants Á Biodiversity hot-spot Á Functional diversity Á Island Á Mediterranean Á Species richness Communicated by Andreas Schuldt.

“…In Crete, the increased tourist presence and other human activities have already degraded the natural coastal environment (Andriotis 2003c;2007;Lambrakis 1998;Legakis et al 1993). Beaches, wetlands and coastal forests already suffer from the presence of hotels, vehicle circulation, cultivation, and recreational activities (Legakis et al 1993:149).…”

Integrated Resort Development: The Case of Cavo Sidero, Crete

Many governments have encouraged integrated resort development in an attempt to improve the well-being of the local population by generating jobs and increasing income and because of the easier control of tourism activities within their boundaries. However, most research reports various adverse environmental and social impacts. Due to the difficulty to assess the impacts that may result from the construction of an integrated resort, the majority of research has been conducted after their construction. This study is an impact assessment carried out prior to a large scale development aiming to examine whether an integrated resort proposed for development in Cavo Sidero, Crete, will result in positive impacts to the destination and the local community and to investigate whether any conflicting interests have arisen within stakeholder groups. Through a primary research of various stakeholder groups it is revealed that economic impacts are perceived as mostly positive, while social and environmental impacts, in many cases, are viewed as negative, and that conflicting interests have arisen within different stakeholder groups.

“…Other occasionally used measures included vulnerability or risk (Gosselink et al 1990b), extent of human interference (Legakis et al 1993), presence of endangered species or species of special concem (Legakis et al 1993, Reimold 1994, importance for bird migration (Legakis et al 1993, Reimold 1994, food web support (e.g., net primary productivity, chlorophyll a, biomass available for consumption) (Klopatek 1988), hydrologic characteristics (PERL 1990), nitrogen and phosphorous levels (Childers and Gosselink 1990), soil conditions (PERL 1990), water-quality parameters (PERL 1990), and flood-protection potential (Bartoldus et al 1994). A more comprehensive discussion of the applicability and tradeoffs associated with the use of many of these criteria can be found in Westman (1985) and Kent (1994).…”

A rapid impact assessment method for use in a regulatory context

Assessing the impacts of projects that affect aquatic resources is an integral part of regulatory programs. The time, resource, and technical requirements of existing assessment methods often prohibit their routine use by regulatory staff. Consequently, many evaluations are based on area affected and best professional judgment. In this paper, we present a Rapid Impact Assessment Method (RIAM) that can be used to assess impacts to aquatic resources in a manner that is scientifically defensible, yet easy to implement by regulators, planners, and resource managers. The RIAM provides a framework for assessing impacts while allowing for specialization of evaluation criteria based on the habitat type, region of interest, and specific regulatory, planning, or management goal. Site-specific impacts are assessed by comparing the conditions present at each site prior to project implementation to conditions present after implementation of the project. A set of evaluation criteria is defined to reflect the important ecological characteristics to be evaluated. Each project site is given a pre-and post-project rating for each evaluation criterion, ranging from A for site conditions similar to those present at reference sites to E for the most degraded condition. Impact scores for each criterion, ranging from -4 to +4, are based on the difference between the pre-and post-project rating levels at each site. We demonstrate the application of the R/AM by using it to assess the impacts of projects permitted under Section 404 of the Clean Water Act on the following six evaluation criteria: endangered species habitat, structural diversity of habitat, spatial diversity of habitat, open space habitat, linear contiguity of habitat, and adjacent habitats. In the future, the method developed in this study can be used as a predictive tool to help monitor impacts on an ongoing basis.
