“…This region has had dense human populations since historical times and its natural (particularly riverine) habitats have been subject to intense impacts (Corbacho et al 2003;Ferreira et al 2007). As a consequence of human activities, the populations of several semi-aquatic reptiles are in severe decline (Filippi and Luiselli 2000;Cox et al 2006).…”

The fluvial systems in the north-east of the Iberian Peninsula are highly disturbed habitats, with widespread occurrence of alien species. Previous studies have shown that alien species have a major impact on native freshwater fauna, but it is not known what effect they have on semi-aquatic reptiles. Here the author investigated the factors that influence the occurrence of three species of semi-aquatic reptiles, one turtle (Mauremys leprosa) and two snakes (Natrix astreptophora and Natrix maura), at 261 sites in seven rivers/streams in Girona (north-eastern Spain). The studied semi-aquatic reptiles are habitat generalists which can occupy sections of rivers with altered regimes. The relationships of reptile presence to abiotic niche parameters and the presence of alien species were evaluated, as well as the patterns of pairwise co-occurrence between the reptiles. The presence of alien species did impact one out of three reptiles in this community. The association between both species of natricines was weakly negative, suggesting that interspecific competition does not structure their co-occurrences. The removal of alien species is the most appropriate strategy to preserve the complete diversity of native semi-aquatic reptiles.

“…Osim samoga vodotoka te geomorfoloških i pedoloških elemenata (korita, obala, naplavne ravnice, sedimenata i tala) riparijske zone kao sustav obuhvaćaju biljne i životinjske populacije koje obitavaju na tom prostoru ili se povremeno njime koriste. Riparijske zone karakterizira mozaična struktura na razini krajobraza, staništa i vrsta (Corbacho, 2003). Zbog prijelazna položaja između vodenoga i kopnenoga ekosustava s više ili manje naglim promjenama abiotičkih čimbenika one imaju ekotonalni karakter (Clary i Medin, 1999;Verry i dr., 2004), odnosno mogu se promatrati ne samo kao prijelazno područ-je između susjednih ekosustava nego i kao poseban ekosustav.…”

“…In addition to the water body, and geomorphological and pedological elements (riverbeds, flooded plains, sediments and soils), riparian zones include plant and animal populations that live in the area. The riparian zone is characterised by a mosaic-like structure at the level of landscapes, habitats, and species (Corbacho, 2003). Because of the contact-transition position between the aquatic and terrestrial ecosystems, with more or less pronounced changes in abiotic factors, they have ecotonal character (Clary and Medin, 1999;Verry et al, 2004).…”

Physical geographical analysis and geoecological assessment of potential protected area – the example of the Kupčina river valley, Zagreb County, Croatia

et al. 2018

The middle section of the Kupčina river valley is listed as a natural asset that has been registered, and proposed to be designated as a protected area of the significant landscape category, in the spatial plan of Zagreb County. However, professional criteria for declaring such protected areas are not clearly defined. Therefore, the aim of this paper is to prepare a proposal for research methodology of physical geographic and geoecological surveys of the landscape in order to create an expert baseline study for protection status. The study area is a prevalently agricultural landscape in which the only natural zone is a narrow riparian zone along the riverbed of the Kupčina. For this purpose, the data on geomorphological, soil, and climate characteristics, water resources, and land use were analysed in order to carry out the assessment of land for agricultural use and protection. By using the method of relative relief evaluation, the suitability of the land for agricultural use was determined. Based on the results, it can be concluded that the inner part of the riparian zone of the Kupčina is suitable for protection under the significant landscape category.Ključne riječi: physical geographical analysis, mapping, geoecological evaluation, riparian zone, ecosystem services, nature protection, Kupčina valley U Prostornom planu Zagrebačke županije središnji dio doline rječice Kupčine na popisu je prirodnih vrijednosti evidentiranih i predloženih za proglašenje zaštićenim područjem u kategoriji značajnoga krajobraza. Kako se proglašenje zaštićenih područja obavlja temeljem kriterija koji nisu precizno definirani, cilj je rada izraditi prijedlog metodologije istraživanja fizičkogeografskih i geoekoloških obilježja krajobraza u svrhu izrade stručne podloge za zaštitu i održivo korištenje. S obzirom na to da se radi o agrarnom krajobrazu u kojem jedinu prirodnu zonu predstavlja uska riparijska zona uz korito Kupčine, analizirani su podaci o geomorfološkim, pedološkim i klimatskim obilježjima, vodnim resursima i korištenju zemljišta u svrhu izrade geoekološke baze podataka. Ona je korištena za procjenu pogodnosti zemljišta za agrarno korištenje kao dominirajući krajobrazni element. Za procjenu je korištena modificirana metoda relativnoga vrednovanja zemljišta, a rezultati su u konačnoj geoekološkoj sintezi doprinijeli zaključku da je za zaštitu u kategoriji značajnoga krajobraza prikladan samo uži dio riparijske zone rijeke Kupčine.

Aplicación de índices bióticos de calidad de agua en cuatro arroyos de la cuenca del río Gualeguaychú (Entre Ríos, Argentina)

La acelerada pérdida de calidad de agua en ríos y arroyos, está asociada con pérdida de biodiversidad, por tanto la determinación de parámetros de calidad de agua en estos sistemas acuáticos es fundamental y urgente. El objetivo del trabajo fue estudiar la calidad de agua de cuatro arroyos de la cuenca del río Gualeguaychú, utilizando bioindicadores. El área de estudio se encuentra en la Pampa Mesopotámica, donde se desarrollan actividades agrícolas y ganaderas, y está sujeta a una profunda transformación de sus ecosistemas desde hace dos décadas. Entre 2013-2015, se estudiaron los arroyos García (GA), Los Perros (LP), Santa Bárbara (SB) y La Cañada (LC). Se realizaron muestreos periódicos determinando variables fisicoquímicas, de ribera, macroinvertebrados bentónicos y de audal. Se aplicaron los índices Biótico de Familias (IBF), Biological Monitoring Working Party (BMWP), el Índice Biótico Pampeano (IBPamp) y el Índice de Calidad de Ribera (ICR). Se recolectaron e identificaron 10007 organismos de 67 taxones. Los índices BMWP e IBF determinaron que existe contaminación de severa a intermedia, el IBPamp determinó escasa contaminación. Según el ICR, los arroyos LP, GA y SB, poseen alteraciones en la ribera; LC, no posee alteraciones. Los índices bióticos de calidad de agua y ribera resultaron una herramienta muy valiosa para determinar el estado ecológico de los cuerpos de agua de la zona, sin embargo, debido a la particularidades de la Pampa Mesopotámica, es necesario realizar ajustes que permitan una mejor interpretación de la diversidad regional y de sus variaciones en el espacio y en el tiempo.
