    Formation of initial daily increments in sagittal otoliths of reared and wild Sardina pilchardus yolk-sac larvae (1994)

    Notes: Abstract Daily deposition of growth increments in sagittal otoliths of reared and wild Sardina pilchardus (Walbaum, 1792) larvae from hatching to complete yolk-sac absorption is reported. Increments laid down prior to hatching were observed. A distinct growth increment, ≃ 1 μm wide and located 5 to 7 μm from the focus is laid down on the day of hatching. Subsequently, narrower increments (〈1 μm) are laid down daily throughout the yolk-sac stage. Measurements were made on the maximum radius of the sagittal otoliths of two groups of larvae: 83 larvae reared from fertilized eggs sampled from Ría de Muros (NW Spain), and 239 wild individuals sampled along the northern coasts of the Iberian peninsula. Counting of daily ring increments can provide a direct and valid estimation of larval age without the necessity for later correction.

    Patterns of smoking in Spain (1994)
    Springer
    European journal of epidemiology 10 (1994), S. 595-598

    Notes: Abstract Smoking patterns were examined in 2500 individuals, aged 14–70 years living in Castille and Leon (Spain) in the fall of 1992. Of these, 39.6% were regular smokers, 7.2% were occasional smokers, 14.8% were former smokers, and 30.4% were non-smokers. Sex differences were striking: there was a higher prevalence of regular smokers among males than females, males smoked much more, and were more frequently French-type cigarette smokers. A comparison of the present figures with data from an earlier survey carried out in 1989 suggests that smoking is decreasing in Spain.

    Paracuaria hispanica n. sp. (Nematoda: Acuariidae), a stomach parasite of the pyrenean desman Galemys pyrenaicus Geoffr. (Insectivora: Talpidae), with a redefinition of the genus Paracuaria Rao, 1951 (1994)

    Notes: Abstract Adult and fourth-stage larvae of Paracuaria hispanica n. sp., from the stomach of the Pyrenean desman Galemys pyrenaicus Geoffroy (Insectivora: Talpidae) in northern and central Spain, are described. The new species differs from the other members of the genus Paracuaria (P. adunca and P. soricis), among other morphological details, in its smaller body and spicule sizes, the presence of a cuticular ring around the tip of the female tail, and the existence of lateral alae running longitudinally along its body from the cervical region to the tail. In view of the latter feature, the genus Paracuaria is redefined. The fourth stage larva of the new species is distinguished from that of P. adunca by its monocuspid deirids. P. hispanica occurred in 45% of the 20 host specimens examined.
