- The winds and the waves that carved out today’s coastal landscape of Sines (Portugal)Publication . Fernandes, Jacinta; Bizarro, Joana; Loureiro, Nuno de Santos; Santos, CarlosThe Atlantic maritime winds and waves, as natural forces, shaped the physiography of Sines, a peculiar rocky cliff cape at the western Portuguese coast, as well as cultural processes have shaped its spatial arrangement since ancient times. Despite its small size, Sines port has always been an important maritime trade corner. In the 1970s, winds and waves of modernity reached the Sines coast with an imposing industrial-port complex. We present the history of Sines cape focusing on its landscape dynamics. The patch-corridor-matrix model allowed us to describe the mosaic transformation of such a unique landscape. Spatial information was gathered mostly from historical maps processed with digital tools. A time series of thematic maps (landscape mosaic pattern) was obtained, covering more than 120 years. Current results emphasize that this landscape underwent relevant transformations related to human activities since former times, although disturbance and fragmentation of the landscape were strongly intensified after the arrival of the post-modern wave of the industrial culture. The present study provides a contribution to the history of the Portuguese and Mediterranean coastal landscapes; and results could be used to support decision making in sustainable management of this territory.
- Hatchery efficiency for turtle conservation in Cabo VerdePublication . Martins, Samir; Ferreira-Veiga, Nádia; Rodrigues, Zuleika; Querido, Adélcio; Loureiro, Nuno de Santos; Freire, Kátia; Abella, Elena; Oujo, Carolina; Marco, AdolfoThis paper evaluated the efficiency of beach hatcheries as a conservation tool for threatened sea turtle clutches. During six nesting seasons (2013 to 2018), several thousand high-risk clutches from loggerhead turtles (Caretta caretta) were relocated to a hatchery constructed on the same beach, within the Sea Turtle Natural Reserve (STNR, Boa Vista Island, Cabo Verde). Some parameters like hatching success; incubation period, hatchlings’ morphology and their behavioral response were compared to in-situ clutches.
- Pseudomonads from wild free-living sea turtles in Principe Island, Gulf of GuineaPublication . Oliveira, Manuela; Serrano, Isa; Santos, Jose Pedro; Bilocq, Florence; Pereira, Nuno; Loureiro, Nuno de Santos; Tavares, Luis; Pirnay, Jean-Paul; De Vos, DanielDissemination of antibiotic resistance is a major concern, especially in aquatic environments, where pollution contributes for resistant bacteria selection. These strains may have serious health implications, especially for endangered species, including the sea turtles' hawksbill Eretmochelys imbricata and green turtles Chelonia mydas. We aimed to evaluate the presence of antibiotic resistant pseudomonads in wild sea turtles from Principe Island, Sao Tome and Principe, Guinea Gulf. Isolates were obtained from oral and cloacal swabs of free-living turtles by conventional techniques. Pseudomonads screening was performed by multiplex-PCR (oprl/oprL) and biochemical identification and antibiotic resistance profiling were achieved using Vitek2. All pseudomonad isolates were genotyped by Rep-PCR. Thirteen isolates were oprl-positive and classified as pseudomonads, eight from the genus Pseudomonas with the species P. aeruginosa, P. stutzeri, and P. mendocina, and five co-isolated Alcaligenes faecalis. The P. aeruginosa isolate was also oprL-positive. Regarding isolates susceptibility profile, 38.5% were susceptible to all antibiotics tested, and multidrug resistant (MDR) strains were not identified. DNA fingerprinting did not show any specific clonal-cluster similarity. Data on the worldwide incidence of antibiotic resistance among wildlife is still very scarce, especially concerning remote tropical areas. Since Pseudomonas genus has emerged as a group of increasingly reported opportunistic microorganisms in human and veterinary medicine with high resistance levels, it could be used as a tool for environmental resistance surveillance, particularly considering their ubiquity.
- Análise da acessibilidade de percursos culturais em Faro. Um contributo para a regeneração urbana e o turismo acessívelPublication . Pires Rosa, Manuela; Landim, Isabel; Loureiro, Nuno de SantosO Turismo Acessível para Todos atende ao desenvolvimento de atividades de lazer e tempo livre por todo o tipo de pessoas, independentemente das suas condições físicas, sensoriais, sociais ou culturais. Acontece que na sociedade há um conjunto de barreiras físicas que limitam a atividade turística das pessoas com mobilidade reduzida, sobretudo as com deficiência. Os princípios do Design Universal devem incorporar-se no desenho urbano das cidades, na arquitetura dos edifícios, nos meios de transporte e nas tecnologias de informação e comunicação, de forma a promover a inclusão social e qualidade de vida de todos. Com esta comunicação pretende-se apresentar a análise e o diagnóstico das condições de acessibilidade universal da rede de percursos pedonais, de interesse cultural, localizada no Centro Histórico da cidade de Faro. Pretende averiguar-se se as suas características físicas respeitam as exigências do Regime Jurídico Nacional da Acessibilidade. O diagnóstico é concretizado através de um modelo de avaliação do grau de conformidade dos espaços considerando parâmetros de acessibilidade urbanística. A metodologia aplicada, através de um Sistema de Informação Geográfica, constitui um instrumento de apoio à decisão nos processos de regeneração urbana. Os resultados apontam para situações de inacessibilidade nos percursos culturais comprometendo os objetivos do turismo acessível e sustentável.
- Long-term changes in cork oak and holm oak patches connectivity. The Algarve, Portugal, a Mediterranean landscape case studyPublication . Loureiro, Nuno de Santos; Fernandes, Maria JacintaStructural connectivity can be inferred by several landscape metrics that appear to be relevant for characterizing how landscapes constrain or favor the presence and movement of animal species at the level of the regional landscape. Trends of change can be estimated trough spatial time-series analysis. The use of historical maps increases the time span of analysis of the landscape dynamic, relative to the use of remote sensing-related information. Supported by GIS, in this study, a framework for the analyses of the long-term trends of change in the connectivity of the Algarve regional landscape was used to seize the possibility of expanding the span of the spatial time series by integrating an unpublished agricultural and forest map from the turn of the 19th to the 20th century with another historical map and two recent maps. The total area covered by cork and holm oak-related community patches and their connectivity increased over the 20th century and stabilized in the 21st century. A reflection on Portuguese contemporary land-cover policies is urged, to face the sustainable planning and management challenges concerning biodiversity.
- Proposta metodológica para avaliação da acessibilidade universal em percursos pedonais: o caso do centro histórico de FaroPublication . Pires Rosa, Manuela; Landim, Isabel; Loureiro, Nuno de SantosNum contexto de turismo acessível é necessária a existência de redes pedonais que detenham um conjunto de atributos de qualidade que garantam usabilidade por todos os cidadãos. Garantir um meio físico acessível é considerado um critério de qualidade, que torna as deslocações pedonais mais agradáveis, não só para idosos e pessoas com deficiência, mas para toda a população residente e turistas. No estudo de caso averigua-se se as características físicas das infraestruturas pedonais, de interesse cultural, localizadas no Centro Histórico de Faro, respeitam as exigências do Regime Jurídico Nacional da Acessibilidade. Formula-se uma metodologia de avaliação da acessibilidade universal das infraestruturas pedonais através da construção de indicadores de desempenho. O diagnóstico é concretizado através de um modelo de avaliação do grau de conformidade dos espaços e apresentado espacialmente com recurso a um Sistema de Informação Geográfica. O diagnóstico confirma a existência de infraestruturas pedonais inacessíveis, propõem-se soluções e conclui-se da necessidade de desencadear processos de regeneração urbana que potenciem o turismo cultural acessível. In a context of accessible tourism it is necessary that pedestrian networks hold a set of attributes of quality that guarantee usability by all citizens. An accessible physical environment should be considered as a criterion of quality, which will make pedestrian dislocations more pleasant not only for the elderly and people with disabilities but for the entire resident population and tourists. In the case study it is ascertain whether the physical characteristics of pedestrian infrastructures of cultural interest, located in the Historical Center of Faro, comply with the requirements of the Portuguese Accessibility Legislation. Therefore, it has been created a methodology for assessing the universal accessibility of pedestrian infrastructure through the construction of performance indicators. The diagnosis is achieved through a model of evaluation of the degree of conformity of the spaces and presented spatially with appeal to a Geographical Information System. The diagnosis confirms the existence of inaccessible pedestrian infrastructure, some solutions are proposed and concludes the need to trigger processes of urban regeneration that promote accessible and cultural tourism.
- Effect of body size on the long-term reproductive output of eastern Atlantic loggerhead turtles Caretta carettaPublication . Martins, Samir; Cardona, L.; Abella, E.; Silva, E.; Loureiro, Nuno de Santos; Roast, M.; Marco, A.We assessed the relationship between body size and several important life history parameters to understand the demographic significance of interpopulation variability in the body size of loggerhead turtles Caretta caretta nesting on Boa Vista Island (Cabo Verde). The adult growth rate (0.34 +/- 0.60 cm yr-1), annual mortality rate (0.13, 95% CI: 0.12-0.15) and remigration interval (3.1 +/- 1.2 yr) were independent of curved carapace length (minimum curved carapace length [CCLmin]). Conversely, the body condition index decreased significantly with female CCLmin. The clutch size, mean egg mass, mean hatchling straight carapace length and mean hatchling mass increased significantly with female CCLmin. However, there was no relationship between female size and hatching success. Randomization and bootstrapping were used to incorporate variability when calculating the average individual fecundity over 20 yr, a period that accumulated, on average, 94% of the adult mortality. The overall fecundity during this period increased with carapace length at first maturity (71 cm CCLmin: 815 eggs, 95% CI: 653-863; 80 cm CCLmin: 906 eggs, 95% CI: 822-959; 90 cm CCLmin: 1089 eggs, 95% CI: 926-1415). However, only 8% of the adult females nesting on Boa Vista Island are larger than 90 cm CCLmin, and they produce less than 12% of the total annual egg production. The scarcity of large females might result from a shortage of high-quality foraging grounds where females may reach first sexual maturity at a large carapace length and from the combined effect of a small carapace length at first sexual maturity, low adult somatic growth and high adult mortality.
- Photography, Land-Cover and Land-Use changes, and tourism urbanization: A narrative focused on Hotel do Garbe, Armação de Pêra, Algarve, PortugalPublication . Loureiro, Nuno de SantosThis article is focused on the use of photography to characterize land-cover and land-use changes in a 7.59 km2 study area centered on Hotel do Garbe, in the village of Armação de Pêra, Algarve, Portugal. Orthorectified vertical aerial, oblique aerial and ground-level photographs were the main data sources required to carry out the analysis. In a preliminary approach, a conventional research design was adopted. Based on the available orthorectified vertical aerial photographs, a sixty-year time series, with four homogeneously distributed steps (1958, 1978, 1997 and 2018), was constructed, and maps were produced to support the description of the changes that have taken place. To deepen the analysis, photographs from fourteen picture postcards were recognized as a useful source of information, and the authors of these photographs were considered “involuntary or accidental photo-geographers” whose work was relevant to feed a case study in which human geography and landscape biography sciences are the main narrative axes. The final result proved to be richer than the interpretation only based on the orthorectified vertical aerial photographs, and the importance of combining photographs taken from different points of view, with different aims and for different recipients is highlighted.
- The status of Ischnura senegalensis (Odonata: Coenagrionidae) in Cape VerdePublication . Loureiro, Nuno de Santos; Martins, S.The first record of a zygopteran breeding population in the Cape Verde archipelago is presented. A small population of Ischnura senegalensis (Rambur, 1842) was found living in the lagoon 'Lagoinha', Santiago island, where the species was observed in all seven surveys conducted between May 2014 and June 2015. Reproductive behaviour was repeatedly observed and exuviae were found and collected.
