“…The marked differences between sites with different kind of human intervention, in studied sites probably is due to the presence of Pyura praeputialis that is a kind of key species that regulate the species composition in rocky shores in northern Chile (Castilla et al, 2004), in this context, in the present study the human altered sites have not P. praeputialis. Also, the low abundances in sites with marked human intervention agree with results for central Chilean rocky shore (Durán and Castilla, 1989) that is similar to the observations for European rocky shore (Stevčić et al, 2018) and Arabian Sea in India (Pandey et al, 2018;Savurirajan et al, 2018) The results about negative binomial distribution agree with similar observations for inland water benthic invertebrates (Gray, 2005;De Los Ríos Escalante and Mansilla, 2017;Ríos and Arancibia, 2018). Also, in recent studies, it has described the use of negative binomial distribution for intertidal environments, specifically in middle intertidal zone, in rocky shores without seaweeds, similar to sites in the present study (Philippe et al, 2016; Checon et al, ).…”

The intertidal rocky shores in continental Chile have high species diversity mainly in northern Chile (18-27° S), and one of the most widespread species is the gastropod Echinolittorina peruviana (Lamarck, 1822). The aim of the present study is do a first characterization of spatial distribution of E. peruviana in along rocky shore in Antofagasta town in northern Chile. Individuals were counted in nine different sites that also were determined their spectral properties using remote sensing techniques (LANDSAT ETM+). The results revealed that sites without marked human intervention have more abundant in comparison to sites located in the town, also in all studied sites was found an aggregated pattern, and in six of these sites were found a negative binomial distribution. The low density related to sites with human intervention is supported when spectral properties for sites were included. These results would agree with other similar results for rocky shore in northern and southern Chile.

“…Although in the present study weak differences were obtained of higher species richness and individual abundances in non-altered sites in comparison to altered sites, these results agree with results for central and southern Chilean rocky shores (Moreno et al, 1984;Durán & Castilla, 1989;Velásquez et al, 2016) and Peruvian coast (Tejada-Pérez et al, 2018). These results agree with observations of null models, of the results of null-model co-occurrence of species that revealed many species repeated by sites, and of niche overlapping, which revealed the absence of (Stevčić et al, 2018) and the Arabian Sea in India; both zones have high productivity and high species richness (Pandey et al, 2018;Savurirajan et al, 2018).…”

The intertidal invertebrate community on rocky shores in northern Chile is characterised by a high species richness resulting from the high productivity of this ecosystem. The present study aims to do the first characterisation of invertebrate communities on rocky shores in Antofagasta town and surroundings (23°S), using species co-occurrence and niche-sharing null models, analysis of similarities (ANOSIM) and nonmetric multidimensional scaling (NMDS). The null model results revealed that species associations are not structured, that the existing species do not have the same ecology, which would result in many repeated species by site, and that specificity in their ecological niches exists. The ANOSIM and NMDS revealed the absence of significant differences between sites with human intervention and without human intervention. The obtained results agree with the literature for northern and central Chilean and southern Peruvian rocky shores, and other coastal marine ecosystems with high productivity.

“…For example, the huge number of visitors to Beijing's Forbidden City has had a significant impact on the palace flooring and stepping-stones [30]. Over-tourism on Spanish beaches has also had an impact on many types of rock, coral reefs, and marine biodiversity [31]. According to [32], population development, urbanization, tourism movement growth, and land use change have all had an impact on the site of Jarash, resulting in visual pollution, flora deterioration, and destruction of many monuments.…”

The archaeological site of Umm Qais is a popular tourist destination for both local and foreign tourists who come to appreciate the site’s archaeological history, scenic landscape, and panoramic perspective. The site was the focus of tourism planning, which included the construction of amenities and infrastructure, the creation of tourist circuits, and archaeological management. This development was linked to a rise in visitor numbers as well as the provision of a high level of service, such as parking, tickets, kiosks, restaurants, and cafés, to welcome visitors. The purpose of this study was to examine the impacts of on-site tourist services and infrastructures, as well as those of visitors, and their geographical and temporal scope on the site. The study used a qualitative approach based on case study fieldwork as a research method to achieve this goal. Personal observation, interviews with site-related stakeholders, and a checklist were used to collect data during the fieldwork. Both tourism infrastructure and visitors were proven to have a detrimental influence on tourist attractions. The site’s aesthetic pollution and structural deterioration were caused by tourism services and infrastructure. Graffiti, vandalism, and trash left by visitors exerted strong negative impacts. Furthermore, spatial and temporal negative impacts were determined by the patterns of seasonal movement of visitors and the location of infrastructure. Thus, most of the impacts were concentrated in a small portion of the site, among the western theater, the panoramic view, and the traditional Ottoman village. This research sheds light on these challenges and makes recommendations in the areas of heritage management, tourism, and visitor impact management that may be of interest to on-the-ground decision makers as well as academics.
