Características biológicas y espectro trófico durante el otoño de dos poblaciones simpátricas de "blennius fzuviatilis" y "micropterus salmoides" en un embalse pequeño
(Asociación Ibérica de Limnología, 1993)Therc exist strong differences in size frequency distribution, fecding habits and in habitat use between the populations of "Blennius fluviatilis" and "Micropterus salmoides" coexisting in a small reservoir in NE Spain. ... -
Species interactions and substrate preferences in three small benthic fishes
(Asociación Ibérica de Limnología, 1997)The interactions between bullhead (Cottus gobio), stone louch (Borbutulu bnrbatulu) and gudgeon (Gobio gobio) and subsequently their influence on the exclusion capacity of these species were examined in laboratory ... -
Habitat use by the fish assemblages of two chalk streams
(1997)Patterns of habitat use by fish assemblages in two chalk streams in southern England were examined to identify species preferences with respect to major habitat gradients. Both study sites although differing in some physical ... -
Distribución espacial de la Nutria (Lutra lutra, L. 1758) en la provincia de Córdoba en el período 1992-96: el uso de hábitat en relación con la disponibilidad de agua
(CUZNA: Revista de Investigación y didáctica en Los Pedroches, 1998) -
Spatio-temporal distribution and ecological preferences of coexisting hydropsychid species (Trichoptera) in two Mediterranean river basins (S Spain)
(1998)The hydropsychids of two Mediterranean river basins in southern Spain (Guadaira and Guadalete) were investigated from January 1988 to January 1989. The distribution of hydropsychids along an environmental gradient related ... -
Distribution and habitat preferences of the introduced mummichog Fundulus heteroclitus (Linneaus) in southwestern Spain
(1998)The distribution and apparent habitat preferences of the common mummichog (Fundulus heteroclitus) in southwestern Spain were examined during summer-fall 1996. This introduced species was more or less continuously distributed ... -
Changes in depth distribution and activity in small benthic riverine fishes under gradually changing light intensities
(Asociación Ibérica de Limnología, 2000)Three experiments were performed to determine how changes in light conditions affect the activity patterns of three small benthic fishes (Barbatula barbatula, Gobio gobio and Cottus gobio) and if they had any influence ... -
Conservation of otter (Lutra lutra) in a Mediterranean area: the importance of habitat quality and temporal variation in water availability
(2001)This study analyses quantitatively the association between habitat characteristics and annual variation in water availability on otter (Lutra lutra L.) distribution in a large Mediterranean area (13717 km(2)) in ... -
Bone length of lberian freshwater fish, as a predictor of length and biomass of prey consumed by piscivores
(Asociación Ibérica de Limnología, 2002)We measured various fish bones from 13 Iberian freshwater fish species and one hybrid species. Original total body lengths were then back-calculated using bone measurements. Bones usually found in prey remains left by ... -
Summer diet of the Iberian chub (Squalius pyrenaicus) in a Mediterranean stream in Sierra Morena (Yeguas stream, Córdoba, Spain)
(Asociación Ibérica de Limnología, 2003)The summer diet of the Iberian chub (Squalius pyrenaicus) was studied in the upper Yeguas river (Córdoba, Spain). The chub showed a wide trophic range, and a pronounced generalist character. The main trophic categories ... -
Los peces continentales de la provincia de Cádiz
(Sociedad Gaditana de Historia Natural, 2003)La ictiofauna continental de la provincia de Cádiz está constituida por 18 especies, de las que 12 son autóctonas y cinco autóctonas estrictamente de agua dulce. Esto significa que más del 50% de las especies de peces ... -
Trophic diversity of the otter (Lutra lutra L.) in temperate and Mediterranean freshwater habitats
(2003)Aim: To analyse the geographical patterns in the composition and diversity of otter’s (Lutra lutra, L.) diet and their relationship with climatic characteristics. Location: European freshwater habitats under Mediterranean ... -
Limnología e Ictiofauna de la Laguna del Tarelo en un Período de Baja Tensión de Oxígeno
(Sociedad Gaditana de Historia Natural, 2003)Se presentan datos relativos a las condiciones limnológicas de la masa de agua y a la comunidad íctica de la laguna del Tarelo durante un periodo de fuerte estratificación química con escasa o nula disponibilidad de ... -
Fish fauna in Iberian mediterranean river basins : biodiversity, introduced species and damming impacts
(2004)We used a basin approximation to analyse distribution patterns of different components of biodiversity (taxonomic richness, endemicity, taxonomic singularity, rarity) and conservation status of freshwater fish fauna in 27 ... -
Seasonal use of coastal resources by otters : comparing sandy and rocky stretches
(2006)Seasonal patterns of use of coastal resources by otters have been Studied, simultaneously performing diet analyses and spraint counts (expressed as marking intensity, MI). In spite of the small size of the study area. ... -
Sobre la presencia de ginetas Genetta genetta (LINNAEUS, 1758) y letrinas en zonas humanizadas
(Sociedad Española para la Conservación y Estudio de los Mamíferos (SECEM), 2006) -
Threats to the conservation of biotic integrity in Iberian fluvial ecosystems
(Asociación Ibérica de Limnología, 2006)Fluvial ecosystems are highly modified by human activity and the species inhabiting them are more imperiled than their aerial or oceanic counterparts. In addition, freshwater biodiversity per surface unit is higher than ... -

Spatial distribution of exotic fish species in the Guadiana river basin, with two new records
(Asociación Ibérica de Limnología, 2008)This work updates the spatial distribution of the exotic fish species in the Guadiana river basin. To this effect, 241 river stretches and 37 reservoirs and lakes were sampled, corresponding to 261 UTM 10 × 10 Km squares. ...
