This study analyzes the impact of the distribution of coconut (Cocos nucifera L.) on the beaches of the Dominican Republic and its relationship with coastal erosion and the dynamics of beach-dune systems. A total of 31 beach-dune systems were compared using 17 qualitative variables to assess the influence of palm trees planted for agricultural or touristic purposes on beach morphology, anthropic occupation, and dynamics. The results indicate that beaches with palm trees planted for touristic purposes exhibit higher compaction, slumping, and erosion, as well as lower resilience in the beach-dune system. These beaches also have a higher presence of tourist complexes, mechanical cleaning, and removal of vegetal debris, which contributes to the alteration of the beach profile and native vegetation. Palm trees can also act as wave flow accelerators, exacerbating sediment loss and increasing the risk of the palms themselves falling, which entails personal risks. It is concluded that the removal of coconut palms and comprehensive beach restoration, including the recovery of dune fronts and associated vegetation, are necessary actions to improve the stability and dynamics of Dominican coasts. Furthermore, the importance of developing planning and management strategies that promote the conservation and restoration of beach-dune systems in touristic and agricultural areas is suggested.

This study analyzes the structure and dynamics of the coastal juniper forest of Punta de la Creueta in Tarragona, comparing it with juniper forests of the island of Mallorca.

The central element is the 1:25,000 geological map; the rest are called peripheral elements. The peripheral elements are: the legend of the cartographic units, the conventional signs, the stratigraphic columns, the geological sections, the stratigraphic relationship diagram, the geological diagram and the complementary diagrams. The geological map shows the distribution of different types of rocks that emerge on the surface of the earth and their relative arrangement. It allows us to deduce much of the arrangement of rocks in the subsoil and to learn about the geological history of a region. It is a two-dimensional graphic representation that allows us to make extrapolations in three dimensions or, even, four if time is considered, depending on the level of reading that is made. It is formed by a set of cartographic units limited by contacts and by symbols that represent other geological elements: surface dip, folding structures, subsoil information (isopachs or isobaths of the Quaternary), slope of recent deposits, morphological indications, landslides and other recent processes, deposits, etc. It also includes symbols of various references (geological sections, drillings, names of major geological structures, etc.).

1D/2D geophysical data, obtained through the application of different geophysical methods in different locations in Catalonia, consisting of the measurement of different physical parameters of the subsoil to obtain information on the behavior of its materials and its structure throughout the territory. Specifically, this set of information includes data, profiles and models resulting from the application of the following geophysical techniques: Magnetotelluric (MT); Electrical Tomography (ERT); Vertical electric sounding (SEV); Seismic refraction Survey (SRA); Seismic reflection survey (SRX); Surface wave analysis (MASW); H/V spectral quotient; Passive seismic array (ARRAY); Geophysical testing in wells.
