The respective “lectotypes” designated by Burdet and collaborators 1983 for the names Bellis pappulosa, Carduncellus hispanicus, Centaurea bombycina, Erigeron frigidus and Senecio quinqueradiatus (Compositae) are ineffective, being contrary to Art. 9.3 of the International Code of Nomenclature. These species were described by Augustin Pyramus de Candolle from material collected by Edmond Boissier, and the material used by the author and the herbarium where it is preserved is specified in their respective protologues. Specimens preserved at G-DC should be considered as holotypes for each of these names. Los respectivos “lectótipos” en el herbario G-BOIS designados por Burdet y colaboradores en 1983 para los nombres Bellis pappulosa, Carduncellus hispanicus, Centaurea bombycina, Erigeron frigidus y Senecio quinqueradiatus (Compositae) deben desestimarse ya que fueron designados en contra con lo dispuesto en el Art. 9.3 del Código Internacional de Nomenclatura. Estas especies fueron descritas por Augustin Pyramus de Candolle a patir de material recolectado por Edmond Boissier, en cuyos respectivos protólogos se especifica el material usado para las descripciones y el herbario donde está conservado. Especímenes conservados en el herbario G-DC deben considerarse como holótipos para cada uno de estos nombres.

Several species of Culicoides (Diptera: Ceratopogonidae) are vectors of pathogens, such as the bluetongue (BTV) and Schmallenberg (SBV) viruses, which cause important diseases in domestic and wild ruminants. As wild ruminants can contribute to overwintering and epizootics of both diseases, knowledge of the host-feeding behaviour of Culicoides in natural ecosystems is important to better understand their epidemiology. Blood-engorged Culicoides females trapped in natural areas inhabited by different wild ruminant species were genetically analysed to identify host species. The origin of bloodmeals was identified in 114 females of 14 species of Culicoides. A total of 104 (91.1%) Culicoides fed on mammals and 10 (8.9%) on birds. The most abundant host identified was red deer (66.7%), followed by humans (13%) and fallow deer (6.1%). Eleven of the 14 species of Culicoides fed exclusively on mammalian hosts. Among them, five are mammalophilic species considered to be important BTV and/or SBV vectors. The results of the present study confirm that Culicoides imicola, Culicoides obsoletus, Culicoides scoticus, Culicoides pulicaris and Culicoides punctatus fed on wild ruminants, and therefore support the hypothesis that these species can act as bridge vectors by facilitating the circulation of pathogens between wild and domestic ruminant communities. info:eu-repo/semantics/acceptedVersion

Esta obra se ordena esencialmente a facilitar la identificación de las plantas vasculares autóctonas o naturalizadas en la península ibérica e islas Baleares. Este volumen XVI (II) está dedicado a las Compositae.

The genus Baldellia Parl. has always been a complex taxon. Three species and three subspecies have been proposed for the Iberian Peninsula. The morphological variation of this genus in the Iberian Peninsula, Balearic islands and northern Morocco, and its thermo-pluviometric and altitudinal correlation are the focus of this contribution. Twenty-eight morphological variables were examined and subjected to a multivariate statistical analysis. The three morphotypes observed (Form 1, which includes B. ranunculoides subsp. repens and B. alpestris; Form 2, which includes B. ranunculoides and Form 3 – for the new combination B. ranunculoides subsp. ranunculoides var. tangerina (Pau) J. Rocha, A. Crespo´, M. Garco´a-Barriuso, R. Almeida, J. Honrado, comb. nova proposed here for the first time) seem to represent different reproductive strategies. Morphological variables related with the presence or absence of stolons and the architecture of the inflorescence; the size and number of fruits are the most discriminating variables. Form 1 represents the asexual morphotype; Forms 2 and 3 correspond to morphotypes for which sexual reproduction is preferential. The environmental approach revealed that the asexual form (Form 1) grows in temperate, in more humid conditions, and within a broad altitudinal range. In contrast, the two sexual forms are more common in warmer and drier conditions, and occur over a narrower interval of altitudes.

The emerging disease West Nile fever is caused by West Nile virus (WNV), one of the most widespread arboviruses. This study represents the first test of the vectorial competence of European Culex pipiens Linnaeus 1758 and Stegomyia albopicta (= Aedes albopictus) (both: Diptera: Culicidae) populations for lineage 1 and 2 WNV isolated in Europe. Culex pipiens and S. albopicta populations were susceptible to WNV infection, had disseminated infection, and were capable of transmitting both WNV lineages. This is the first WNV competence assay to maintain mosquito specimens under environmental conditions mimicking the field (day/night) conditions associated with the period of maximum expected WNV activity. The importance of environmental conditions is discussed and the issue of how previous experiments conducted in fixed high temperatures may have overestimated WNV vector competence results with respect to natural environmental conditions is analysed. The information presented should be useful to policymakers and public health authorities for establishing effective WNV surveillance and vector control programmes. This would improve preparedness to prevent future outbreaks.
