    Estudio de los mixomicetos que fructifican sobre Opuntza fzcusindica l. en el S.E. de España peninsular
    (Murcia: Universidad de Murcia, Servicio de Publicaciones, 1986) López-Sánchez, E.; Honrubia García, Mario; Gracia, E.; Gea, F. J.; Facultad de Biología
    Fifteen species of Myxomycetes that grow on Opuntia ficus-indica, ín South-East Spain are cited. One of them (Stemonitis virginiensis) in this substrate is collected only in moist-chamber. According to the abundante and frecuency with which the other fourteen species are registered, three groups of species are distinguished: five «characteristic» species, three «frequent» species and six «occasional» species. Badhamia gracilis is the most common one. When cultures in moist chambers were prepared sporocarps of Badhamia gracilis, Stemonitis virginiensis and Perichaena minor developed. Three species considered as «characteristic»: Badhamia gracilis, Physarum compressum and P. stramir:ipes have been cultivated in vitro. Three species widely distributed in the area studied, but that have never been collected on O. ficus-indica, were used to compare with the ones isolated in the Opuntia. Three media of culture: CM, CM/2 and carrot-agar have been used and also a new medium, prickly-agar, has been pul to test.

    Estudios ecológicos de los humedales costeros del Sudeste español. I. Inventario y tipificación
    (Murcia: Universidad de Murcia, Servicio de Publicaciones, 1991) Robledano Aymerich, Francisco; Calvo Sendín, José Francisco; Esteve Selma, Miguel A.; Más, J.; Palazón Ferrando, José Antonio; Suárez Alonso, María Luisa; Torres, A.; Vidal-Abarca Gutiérrez, María Rosario; Ramírez-Díaz, Luis; Facultad de Biología
    Este es el primero de dos artículos sobre las características ecológicas de los humedales costeros del SE de España. En él se presenta un inventario de los complejos palustres de la franja costera comprendida entre la ciudad de Alicante y el límite occidental de la Región de Murcia, se revisa la información publicada e inédita existente sobre sus características ecológicas, y se establece una tipología de los mismos basada en variables del medio físico y biótico. Excluyendo los estrictamente artificiales, se han registrado 16 humedales comprendidos en nueve tipos. Se discuten las semejanzas de la tipología obtenida con otras clasificaciones de humedales, así como la contribución de las distintas variables a la tipificación.

    El Tarro Blanco tadorna tadorna (l.) en el Sureste Español
    (Murcia: Universidad de Murcia, Servicio de Publicaciones, 1987) Calvo Sendín, José Francisco; Castanedo García, J. L.; García Giménez, F. J.; Ibáñez González, J. M.; Más Hernández, J.; Rebollo Castejón, I. D.; Robledano Aymerich, Francisco; Facultad de Biología
    The Shelduck (Tadorna fadorna) is one of the most representative among the duck species in the wetlands of south-eastern Spain, and the only one of numerical significance in some of them. In our country, the species has changed its status from being considered an ocasional winter visitor to a regular winter presence, having also settled as a breeder in some localities. The south-eastern o€ Spain is one of the main winter quarters of Shelduck in our country, and the only area where it breeds besides the Ebro Delta. This paper summanzes a number o€ observations on Shelduck made in this area from 1976 to 1985, regarding the numerical evolution o€ the wintering and breeding populations, together with several data on its biology and ecology. The study area includes anumber of wetlands belonging to the provinces of Murcia (Salines o€ San Pedro del Pinatar, Marchamalo and Rasall) and Alicante (Salines of Santa Pola, La Mata Lagoon and El Hondo Reservoirs). Excepting for the latter, flooded with freshwatercomingfrom the Segurariver, al1 these areas are hypersaline lagoons transformed by man for salt production. The wetlands of south-eastern Spain set up the second or third winter quarter, in importante, in the Iberian Peninsula, after the Marismas o€ the Guadalquivir and the Ebro Delta. Data on wintering Shelduck are scarce until the winterof 1980-81, which may be partly due to a poor prospectingeffort. However, from this winter onwards the population has markedly increased, the presence of the wintering birds becoming more regular. The total winter fgures show marked oscilations, both between and within years, but the general trend of the population is to increase. The main wintering localities are the Salines of San Pedro del Pinatar and La Mata Lagoon. The first evidence o€ Shelduck breeding in south-eastern Spain comes from the Salines of San Pedro del Pinatar, where a pair settled in 1976. From 1982 onwards, the species has also bred in La Mata Lagoon and, less regularly, in the Salines of Rasall (from 1982 to 1984), Santa Pola(at least two years) and El Hondo Reservoirs (only in 1985). The increase in the number o€ breeding pairs and the settlement of new breeding colonies usually occurs two years after a good breeding success, when the birds reared locally reach maturity. However, this increase may also be explained by immigration, mainly from the Camargue (France). Birds hatched in this locality have been reponed wintering in the spanish mediterranean coast, and the increase in the breedingpopulation of south-eastern Spain probably reflects the great success of the french breeding colony. The use of rabbit (Orycrolagits crinicrrl~is) burrows by Shelduck for nesting has been confirmed in La Mata Lagoon, and there is strong evidende ofthe choice of similar sites in other localities. The number of Shelducklings per brood is low compared with the average figures given for the species. The occurrence of multiple nesting is rare. Ducklingsurvival changes markedly between localities, from almost 100% in La MataLagoon to the loss o€ al1 the ducklings of a pair breeding in the Salines o€ Rasall in three breeding seasons. In the Salines of San Pedro del Pinatar, duckling survival seems related to hatching date, the pairs breeding later in the season losing almost al1 their ducklings as an effect of human pressure, while the earliest ones fledge almost al1 their young. In other localities, like the Salines of Santa Pola, the absence o€ a regular breeding population is discussed in terms of the availability and interspecific competence for nesting sites.
