“…In the Iberian Peninsula, two historical factors are significant in defining present aquatic biota: (1) the lack of strong glaciations during the Quaternary, which played an important role in increasing biodiversity; and (2) the incorporation of part of the Baetic–Riffian Massif (south and southeast of Spain) with the Hesperic Massif at the end of the Miocene (Baetic ranges) (Rosenbaum, Lister & Duboz, 2002). This joining of the Eurasian and African plates enabled North‐African species to enter the southeast of the Iberian Peninsula and neo‐endemisms to develop there (Ribera et al. , 1996; Ribera, 2000).…”

Ecological and historical filters constraining spatial caddisfly distribution in Mediterranean rivers

SUMMARY1. Contemporary species distributions are determined by a mixture of ecological and historical filters acting on several spatial and temporal scales. Mediterranean climate areas are one of the world's biodiversity hotspots with a high level of endemicity, which is linked to complex ecological and historical factors. 2. This paper explores the ecological and historical factors constraining the distribution of caddisfly species on a large regional scale. A total of 69 taxa were collected from 140 sampling sites in 10 Iberian Mediterranean river basins. Approximately 74% of taxa can be considered rare, with the southern basins (the Baetic-Riffian region) having greater endemicity. The greatest richness, involving a mixture of northern and southern species, was found in the transitional area between the Baetic-Riffian region and the Hesperic Massif. 3. The historical processes occurring during the Tertiary (i.e. the junction of the Eurasian and African plates) explained 3.1% of species distribution, whereas ecological factors accounted for 20.7%. Only 0.3% was explained by the interaction of history and ecology. A set of multi-scale ecological variables (i.e. basin, reach and bedform characteristics) defined five river types with specific caddisfly assemblages. The commonest caddisfly species accounted for the regional distribution pattern, while rare taxa contributed to the explanation of subtle patterns not shown by common species. 4. Despite the importance of historical factors for biogeography and the large scale used in our study, ecological variables better explained caddisfly distribution. This may be explained by the length of time since the historical process we are considering, the high dispersion and colonisation capacity of many caddisfly species, and the strong environmental gradient in the area. Because of the historical and environmental complexity of Mediterranean areas, rare taxa should be included in ecological studies so that the singularity of these ecosystems is not missed.

“…Most of the species of water beetle collected had a wide Palearctic distribution and only three species could be considered endemic to Iberia: Hydroporus vagepictus, Hydroporus vespertinus and Hydrochus angusi (Ribera et al, 1999;Ribera & Vogler, 2004). The paucity of endemics among coastal water beetles has been attributed to the temporal dynamics of the lagoons and their recent origin in geological time, as most of the sites are 'temporary' on a scale of a few hundred years (Ribera et al, 1996) and this could also apply to aquatic Hemiptera. According to Ribera & Vogler (2000), stagnant water bodies present less endemic species than running waters, because stagnant species have a greater dispersal capability and thus a greater geographical distribution.…”

“…Compared with other coastal stagnant water bodies in the Iberian Peninsula and the Balearic Islands, species richness of these coastal lagoons can be considered high. It is important to highlight that only three lagoons were sampled, when in other studies the number of sampling sites is much higher, e. g. 13 coastal wetlands in Ribera et al (1996), 9 sites in Garrido et al (1996Garrido et al ( , 1997, 22 ponds in Florencio et al (2009) or 38 lagoons in Lucena-Moya et al (2010). A richer Coleoptera assemblage seems to be the rule in aquatic insect communities where the proportion of Coleoptera to Hemiptera usually varies from 3:1 to 4:1 (Eyre & Foster, 1989;Lancaster & Scudder, 1987;Millán et al, 1997Millán et al, , 2001Moreno et al, 1997).…”

“…E. halophilus is classified as "vulnerable" on the red list of Irish threatened species (IUCN) (Foster et al, 2009). This species was found in wetlands in the Mediterranean coast of Spain in eutrophic or even in high salinity waters (Bigot & Marazanof, 1966;Ribera et al 1996). E. fuscipennis has been found in stagnant water rich in organic matter (Valladares, 1995).…”

“…This is similar to the finding of previous studies on communities of Hydradephaga in the Iberian peninsula (e.g. Garrido et al, 1994;Ribera et al, 1996),but is particularly important in the Segura basin, where there is a wide range of ecological conditions, and a large proportion of highly mineralised water bodies due to both the soil type and the general climatology. The amount and type of riparian vegetation is likely to play more of a structural role, conditioning the availability of refugia, the suitability of oviposition sites and the presence of prey (e.g.…”

-We present the results of 25 years of study of the faunistics, biogeography, ecology and conservation of the Hydradephaga of the Segura river basin. Eighty one species have been recorded from the area, ca. 45% of the total of species found in the Iberian peninsula. Six of them are Iberian endemics, and fourteen are considered to be rare within the basin, although most of these are not rare in an Iberian context. The phenetic hierarchy of relationships among the western-Palaearctic regions considered shows a clear similarity of the fauna of the Segura basin with that of the Maghreb, which, together with the rest of the Iberian fauna form a well defined group isolated from the rest of the European areas. Within the Iberobalear region, there is also a clear north-south division, with a secondary classification into western and eastern basins. The Balearic islands seem to be a relatively independent biogeographical unit, although more related with the southern cluster. The environmental characteristics determining the distribution of the Hydradephagan fauna in the study area, as determined by Correspondence Analysis, are altitude, degree of mineralization of the water, and amount and type of riparian vegetation. Using a semi-quantitative scoring system to evaluate the vulnerability of the species only Hydroporus decipiens had a vulnerability value considered to be high (9), due to its rarity within the basin and to its general restricted distribution, although the incomplete knowledge of its distribution and taxonomy could be a distorting factor. With a similar value (8), Nebrioporus baeticus is a typical inhabitant of saline running waters, highly endangered habitat due to the increasing use of irrigation in the surrounding fields. The stations with the highest conservation interest were mountain streams in the NW of the basin, which are also of high conservation interest for other aquatic Coleoptera (e.g. Hydraenidae). A disadvantage of the index applied (IC, "conservation interest") is the lack of reference to the conservation interest of habitats outside the study area. Thus, the saline or hypersaline streams, which are extremely rare in an European (or even global) context, are not considered of particular relevance due to the poor species richness and local abundance. The use of other criteria for the selection of sites of conservation value, such as complementarity, could overcome this limitation.
