Abstract: Since the first authorised introductions to Spain in 1921 of the Eastern mosquitofish Gambusia holbrooki (Girard, 1859), this North American freshwater fish species has invaded large parts of several Iberian basins. For the River Ebro basin, we report 24 new records of this exotic species between 2005 and 2007 which represents a considerable expansion. Potential negative implications for aquatic invertebrate and fish communities are discussed.2008-01-01T00:00:00ZFirst record of Trocheta subviridis Dutrochet, 1817 (Arhynchobdellida, Erpobdellidae) from the north-eastern Iberian Peninsula (Navarra, Spain)https://hdl.handle.net/10171/654932024-02-09T14:42:06Z2023-01-01T00:00:00ZTitle: First record of Trocheta subviridis Dutrochet, 1817 (Arhynchobdellida, Erpobdellidae) from the north-eastern Iberian Peninsula (Navarra, Spain)
Abstract: We reported the first record of the rare species Trocheta subviridis Dutrochet, 1817 (Arhynchobdellida, Erpobdellidae) from north-eastern Spain (Suspiro stream at Señorio de Bértiz Natural Park, Navarra, Spain). The species was previously recorded in Spain by Cordero del Campillo (1980) and García Más and Jiménez (1981). However, the latter authors admitted (Garcia Más & Jiménez, 1984) that both citations could be considered erroneous due to a misinterpretation by Cordero del Campillo of Blanchard (1893) (Jueg, 2008). Thus, considering the limited and uncertain information about T. subviridis in Spain, we can argue that our specimen is the first valid record reported for the species in the Iberian Peninsula.; En esta publicación reportamos el primer registro de la rara especie Trocheta subviridis Dutrochet, 1817 (Arhynchobdellida,
Erpobdellidae) en el noreste de España (arroyo Suspiro en el Parque Natural del Señorío de Bértiz, Navarra, España). La
especie fue registrada previamente en España por Cordero del Campillo (1980) y García-Más y Jiménez (1981). Sin embargo,
estos últimos autores admitieron (García Más y Jiménez, 1984) que ambas citas podrían considerarse erróneas debido a una
mala interpretación de Blanchard (1893) por parte de Cordero del Campillo (Jueg, 2008). Por lo tanto, teniendo en cuenta la
limitada e incierta información sobre T. subviridis en España, podemos argumentar que nuestro ejemplar es el primer registro válido citado para esta especie en la Península Ibérica2023-01-01T00:00:00ZDistribución de especies del género Sympetrum Newman, 1833 (Odonata, Libellulidae) en Castilla y León, NW de Españahttps://hdl.handle.net/10171/654922023-05-03T11:44:12Z2022-01-01T00:00:00ZTitle: Distribución de especies del género Sympetrum Newman, 1833 (Odonata, Libellulidae) en Castilla y León, NW de España
Abstract: La distribución geográfica de insectos odonatos en la península ibérica se ha analizado profusamente en los últimos años, aunque una amplia superficie del NW permanece aún poco estudiada. En este trabajo se presenta la distribución de especies del género Sympetrum (Odonata, Libellulidae) en la cuenca del río Duero, España, donde la variedad de condiciones orográficas y climáticas es grande. Seis especies han sido registradas: S. fonscolombii, S. meridionale, S. sanguineum, S. striolatum, S. vulgatum y S. flaveolum. Un modelo lineal generalizado con datos de altitud sobre el nivel del mar, latitud, temperatura media del aire y pluviosidad anual obtenidos en 25 puntos de muestreo mostró que estos cuatro factores conjuntamente pueden explicar la distribución de S. fonscolombii, S. striolatum y, sobre todo, S. sanguineum. La distribución de S. meridionale está influida por la latitud y la pluviosidad anual. En el presente estudio se ratifica que las especies S. vulgatum y S. flaveolum están asociadas sobre todo a zonas de montaña.; The geographic distribution of dragonflies in the Iberian Peninsula has been abundantly analyzed in recent
years, though a vast area of the NW has been little studied to date. This paper presents the distribution of species
of the Sympetrum genus (Odonata, Libellulidae) in the basin of the Duero River, Spain, where many variations in
climate and orographic conditions are found. Six species have been recorded: S. fonscolombii, S. meridionale, S.
sanguineum, S. striolatum, S. vulgatum and S. flaveolum. A generalized linear model with data of altitude above
sea level, latitude, mean air temperature, and annual rainfall obtained in 25 sampling points showed that these four factors together explain the distribution of S. fonscolombii, S. striolatum and, above all, S. sanguineum. The distribution of S. meridionale is influenced by latitude and annual rainfall. In the area of study, the species S. vulgatum and S. flaveolum are associated above all with mountain zones.2022-01-01T00:00:00ZCollembola from two samplings in the MSS of the Sierra de Guadarrama National Park in two different seasons, with description of two new specieshttps://hdl.handle.net/10171/649502022-12-26T06:07:08Z2022-01-01T00:00:00ZTitle: Collembola from two samplings in the MSS of the Sierra de Guadarrama National Park in two different seasons, with description of two new species
Abstract: An intensive sampling in a colluvial mesovoid shallow substratum (MSS) of the Sierra de Guadarrama National Park, using 33 subterranean sampling devices (SSDs) is the origin of the Collembola studied in this paper. The data were obtained from the second extraction of the traps, in operation between October of 2015 and May of 2016. This paper presents the faunistic and diversity data along with the entire park (mostly at sampling points above 200 m a.s.l.) for this period, compares the data between the first extraction of the traps and the second one, and describes one species of the genus Pseudosinella that appears as new in the second campaign.2022-01-01T00:00:00Z
