    El clima de la cuenca del rio Segura (S. E. de España): factores que lo controlan
    (Murcia: Universidad de Murcia, Servicio de Publicaciones, 1987) Vidal-Abarca Gutiérrez, María Rosario; Montes, C.; Ramírez-Díaz, Luis; Suárez Alonso, María Luisa; Facultad de Biología
    Se han empleado los datos termopluviométricos de 65 estaciones meteorológicas localizadas en la Cuenca del Segura (S.E. de España), para caracterizar sectores climáticos homogéneos en la misma. El análisis de la información se llevó a cabo en varias fases y sobre distintos tipos de matrices, aplicando técnicas estadísticas de ordenación. Para detectar las posibles influencias que, sobre el clima de la cuenca, ejercen dos factores del medio físico: altitud y proximidad al mar, se aplicó un análisis de regresión lineal múltiple paso a paso multiple linear Los resultados obtenidos permiten definir diez tipos de sectores climáticos, a modo de gradientes termopluviométricos, donde destacan algunos que funcionan como de notable peculiaridad e interés ambiental.

    Destinos turísticos patrimoniales: su vulnerabilidad ante las variabilidades del clima
    (Escuela Universitaria de Turismo de Murcia, 2011) Herrera Pupo, Gerson; Perera Téllez, Geiser
    Ante el amenazador y perenne impacto producido por el clima y en específico por la interrelación de este con las actividades invasivas del hombre al desarrollo de nuestras ciudades y de su desarrollo turístico, y en específico de nuestro patrimonio urbano heredado, es que se hace necesaria la presente investigación. Como objetivo fundamental se presenta la interrelación entre impactos físicos e impactos sensoriales (somático, olfativo, visual y sonoro) y sus posibles consecuencias, que deben ser tenidas en cuenta en determinado espacio turístico patrimonial. Se realiza una discusión teórica relativa a la interrelación clima - patrimonio - turismo.

    First confirmed outdoor winter reproductive activity of Asian tiger mosquito (Aedes albopictus) in Europe
    (Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2014) Collantes Alcaraz, Francisco; Delgado, Juan A.; Alarcón Elbal, Pedro María; Delacour Estrella, Sarah; Lucientes Curdi, Javier
    Es la primera vez que se registra la continuidad en invierno del ciclo reproductivo de Aedes albopictus en Europa. Se discute sobre el empleo de la variable precipitación en los modelos de riesgo de implantación de mosquito tigre. Pensamos que la disponibilidad local de agua para estos insectos no depende siempre de la lluvia

    Growing snow volleyball in snow-restricted countries: A pilot study
    (Servicio de Publicaciones. Universidad de Murcia, 2025) Bahdur, Zarina; Dell'Oca, Duane; Bahdur, Khatija; Sin departamento asociado
    Snow volleyball is an increasingly popular sport that has been earmarked as a potential Winter Olympic discipline. However, it is not typically associated with Africa. This study provided an in-depth retrospective exploration of the experience of an African player who participated in the inaugural Snow Volleyball World Championships in 2019. Through a focused one-on-one interview, the study examined her transition to snow volleyball, the challenges she faced, and her insights into the feasibility of African participation in the sport. Drawing from both her tournament experience and her broader knowledge of the volleyball landscape, she identified key barriers such as climate, accessibility, and financial constraints, while also proposing strategies to improve feasibility. These include leveraging African players competing in European leagues, developing training opportunities in North Africa, and exploring artificial snow environments. While the study primarily focuses on the player's personal journey, it also highlights pathways for the sport’s potential expansion in non-snow countries. This qualitative study serves as a pilot for a larger investigation into the introduction of snow volleyball to regions without winter sports traditions.

    Month of birth and height. A case study in rural Spain
    (Elsevier, 2022-07-06) Candela Martínez, Begoña; Ramallo-Ros, Salvador; Cañabate, José; Martínez Carrión, José Miguel; Economía Aplicada; Facultad de Economía y Empresa
    Introduction: Season of birth correlates to a wide range of health conditions throughout life measured by anthropometrics. This study explores whether the month of birth and weather during gestation influence male adult height, based on Spain’s rural population before the end of the modernization process. Methods: The database of heights (N = 16.266) is composed of conscripts who reached the age of 21 between 1908 and 1985 (birth cohorts 1886–1965). The population sample has been taken from a municipality in inner Spain: Hellín, in the region of Castilla-La Mancha, mainly an agrarian area, with poor resources and low income until the 1970 s/1980 s. Two different methodologies have been implemented: a harmonic regression using sinusoidal covariables and a random forest model. Results: we find that being born at the end of the summer and during the autumn was favorable to height. The birth month with the highest statures is September, with heights 0.5 cm above the annual average and 0.9 cm above February, the birth month with the lowest average height. Furthermore, we can observe that rainfall and temperature during gestation had little additional influence due to a substitution effect with the birth month variable. Conclusions: Our results suggest that the seasonal effects on height can be significant and that it can be partially affected by environmental factors during early life. Our findings could be of interest for low-income populations and developing rural societies.

    El papel del clima en la estacionalidad turística y la configuración de productos turísticos emergentes. El caso de Mallorca
    (Murcia: Universidad de Murcia, Editum, 2014) Coll Ramis, Miquel Àngel; Seguí Llinás, Miguel
    La estacionalidad ha sido un fenómeno ampliamente abordado dentro de la literatura científica, especialmente a partir de planteamientos economicistas sobre sus causas y consecuencias. En este sentido, el presente artículo pretende ofrecer un enfoque alternativo, basado en el análisis de la influencia de las condiciones climáticas, sobre el fenómeno de la estacionalidad turística en Mallorca. Para ello, se ha realizado un análisis del potencial climático-turístico que dispone la isla, el cual, nos permite observar que la estacionalidad, a diferencia de lo que se viene justificando históricamente, es más bien consecuencia de otros factores socio-económicos que no del clima propiamente dicho.

    The role of zoological centers as reservoirs of Leishmaniosis in urban áreas
    (BioMed Central, 2017-04-19) Risueño, José; Muñoz, Clara; Pérez Cutillas, Pedro; Ortuño, María; Bernal, Luis Jesús; Ortiz Sánchez, Juana; Alten, Bulent; Berriatua, Eduardo; Goyena Salgado, Elena; Gonzálvez Juan, Moisés; Sanidad Animal
    Background Leishmaniosis is associated with Phlebotomus sand fly vector density, but our knowledge of the environmental framework that regulates highly overdispersed vector abundance distributions is limited. We used a standardized sampling procedure in the bioclimatically diverse Murcia Region in Spain and multilevel regression models for count data to estimate P. perniciosus abundance in relation to environmental and anthropic factors. Methods Twenty-five dog and sheep premises were sampled for sand flies using adhesive and light-attraction traps, from late May to early October 2015. Temperature, relative humidity and other animal- and premise-related data recorded on site and other environmental data were extracted from digital databases using a geographical information system. The relationship between sand fly abundance and explanatory variables was analysed using binomial regression models. Results The total number of sand flies captured, mostly with light-attraction traps, was 3,644 specimens, including 80% P. perniciosus, the main L. infantum vector in Spain. Abundance varied between and within zones and was positively associated with increasing altitude from 0 to 900 m above sea level, except from 500 to 700 m where it was low. Populations peaked in July and especially during a 3-day heat wave when relative humidity and wind speed plummeted. Regression models indicated that climate and not land use or soil characteristics have the greatest impact on this species density on a large geographical scale. In contrast, micro-environmental factors such as animal building characteristics and husbandry practices affect sand fly population size on a smaller scale. Conclusions A standardised sampling procedure and statistical analysis for highly overdispersed distributions allow reliable estimation of P. perniciosus abundance and identification of environmental drivers. While climatic variables have the greatest impact at macro-environmental scale, anthropic factors may be determinant at a micro-geographical scale. These finding may be used to elaborate predictive distribution maps useful for vector and pathogen control programs.
