Metahadzia uncispina n. sp. is described, being the second species of the genus on the Iberian Peninsula. The new species, well characterized by the transformation of the apical spine on the endopodite of the male uropod 2, is undoubtedly closely related with M. tavaresi (Mateus & Mateus, 1972) from the south of Portugal. Comments are made about recent emendations of the original concept of the genus Metahadzia Stock, 1977.

Smart cities have become a new urban model for thinking and designing cities in the connected society. It is time to ask ourselves what kind of city we want and need. There is still a long way to go in relation to the role of citizenship in the field of smart cities. This autoethnography reveals different contradictions found during the preparation of my doctoral thesis, which studied the citizens’ perception of smart city policies in a city in southern Spain, in my double role as a doctoral student/researcher and public manager. Many of the statements and conclusions of different scientific research contrasted with the reality that I was experiencing in my daily work. My conclusions can help in the current debate on which cities we want to build at a time when the population is concentrated in cities and where it is necessary to respond to not only the economic, but also the social and environmental problems posed by sustainability

AbstractThe predominantly carbonate nature of the mountains near the coast of Málaga and Marbella (Costa del Sol, southern Spain) and the presence of springs have favored the formation of travertine buildups during the Quaternary. The geomorphic characteristics of the slopes and the location of the springs have determined the development of three types of travertine growths: (1) spring travertines, located preferentially on the south mountainside, where the slope is steepest; (2) pool-dam-cascade travertines, which form along the north and east edges, far from the carbonate relief and with a gentler slope; and (3) river-valley travertines, formed in the courses of the springs of any sector. Field observations combined with new amino acid racemization (AAR) dating of Helicidae gastropods show that most of the travertine formations are polyphasic and that their development was interrupted by stages of erosion and incision. Five stages of travertine development are evident, most of which are related to warm, moist episodes corresponding to marine oxygen isotope stages (MIS) 7, 5, 3, and 1, although local travertine growth also occurred during MIS 6 and during the transition from MIS 3 to 2.
