“…Schmera & Erõs (2004) concluded that season, stream order, riverbed morphology and interaction of these factors had a significant effect on the assemblage organisation of caddisflies of natural headwater systems in Hungary. Basaguren & Orive (1990 a) verified the disappearance of Trichoptera from low oxygen sites and the relatively insensitivity of species to conductivity, in the Vasc Country, North of Spain.…”

“…This is in accordance with the literature (Vieira-Lanero 2000) where Rhyacophila relicta is considered an ubiquitous species usually associated to R. adjuncta. Moreover, R. adjuncta and R. tristis, which are considered intolerant to organic contamination (Basaguren & Orive 1990a, Vieira-Lanero 2000, appeared in two groups of clean waters. Rhyacophila lusitanica was represented by two individuals sampled in one site of the Lower Mondego region (Ança).…”

“…The studies on the Trichoptera of the Iberian Peninsula have been taxonomical (McLachlan 1884, Navás 1908, Terra 1972, 1981, 1994, González et al 1992, Vieira-Lanero 2000, focused on the distribution of particular groups such as the Hydropsychidae (García de Jalón 1986), on temporal and spatial distributions (Puig et al 1981, Molles & Terra 1987, Cortes 1992 and relationship with water quality (Basaguren & Orive 1990 a, b). A total of 329 Trichoptera species have so far been reported for the Iberian Peninsula (González et al 1992, Vieira-Lanero 2000 and 167 species for Portugal (Terra 1994).…”

We investigated how diversity and distribution of more than 11000 Trichoptera larvae in streams of central Portugal were related to chemical and physical environmental variables. Sixty-six sites were sampled in 2001, by kicknet, in 55 streams of the Mondego River basin, the largest entirely Portuguese river. Simultaneously 43 environmental variables were evaluated for each site. We identified 18 families and 70 species and genera of caddisflies, representing ≈ 20 % of all trichopteran taxa recorded for the Iberian Peninsula. The species Calamoceras marsupus, Cheumatopsyche lepida, Hydropsyche bulbifera, Hydropsyche siltalai, Hydroptila sp., Lepidostoma hirtum, Mystacides azurea, Chimarra marginata, Polycentropus flavomaculatus, Tinodes waeneri, Rhyacophila adjuncta and Sericostoma sp. were found to be the most important taxa in the Mondego River basin. Stream order, substrate quality, altitude, current velocity and alkalinity explained 41 % of the taxa distribution suggesting that at a wider (catchment) scale physical and hydrological parameters are more important for the distribution of Trichoptera assemblages than chemical parameters. Six significantly different groups of sites with similar Trichoptera assemblages were identified in the catchment and related to altitudinal, hydrological and substrate gradients. Our findings allow us to predict Trichoptera assemblages in streams of the Mondego catchment based on few environmental characteristics.
