Fauna of simuliids (Diptera: Simuliidae) of the Tormes River hydrographic basin in central-western Spain and their responses to abiotic factors in their habitats.

Delving into knowing the blackfly (Diptera: Simuliidae) species composition of Spain and their ecological requirements is crucial, due to their instrumental role in natural food webs as intermediaries in the flow of energy in aquatic ecosystems, and because of the haematophagic behaviour displayed by females of several species. The present study has analysed the abundance and distribution of the larvae and pupae of blackfly species in 105 sampling stations located in lotic water bodies of the provinces of Ávila, Salamanca, and Zamora of the Tormes River basin. The study has allowed to identify 24 species: 17 from Ávila, 13 from Salamanca, and seven from Zamora, classified in three genera (Metacnephia, Prosimulium, and Simulium), and five subgenera (Boophthora, Eusimulium, Nevermannia, Simulium, Wilhelmia).

Spatial versus spatio-temporal approaches for studying metacommunities: a multi-taxon analysis in Mediterranean and tropical temporary ponds.

Prior research on metacommunities has largely focused on snapshot surveys, often overlooking temporal dynamics. In this study, our aim was to compare the insights obtained from metacommunity analyses based on a spatial approach repeated over time, with a spatio-temporal approach that consolidates all data into a single model. We empirically assessed the influence of temporal variation in the environment and spatial connectivity on the structure of metacommunities in tropical and Mediterranean temporary ponds.

Parasite-host relationships of water mites (Acari: Hydrachnidia) and black flies (Diptera: Simuliidae) in southeastern Spain.

Background: Documentation on water mites in Spain is scarce, as is information on the parasite-host relationship between certain water mite species and representatives of the dipteran family Simuliidae. The discomfort caused to humans and animals by black flies seems to be increasing in recent years. In this context, an investigation of parasitic water mites is of great importance, not only from the point of view of biodiversity, but also in terms of their potential to control black fly populations.

Environmental drivers of breeding sites in blackfly species of medical and veterinary importance in eastern Spain.

Geographical distribution and abundance of the pupae of six blackfly species of medical and veterinary concern were studied in eastern Spain according to three different sets of explanatory variables including in-stream variables, both (i) abiotic (i.e., physicochemical) and (ii) biotic (i.
