A comparison of artificial neural networks and random forests to predict native fish species richness in Mediterranean rivers

Olaya Marín, Esther Julia; Martinez-Capel, Francisco; Vezza, Paolo (EDP Sciences, 2013)

[EN] Machine learning (ML) techniques have become important to support decision making in management and conservation of freshwater aquatic ecosystems. Given the large number of ML techniques and to improve the ...
Analysis of monitoring programmes and their suitability for ecotoxicological risk assessment in four Spanish basins

López Doval, Julio C.; De Castro Catala, Núria; Andrés Doménech, Ignacio; Blasco, Julián; Ginebreda, Antoni; Muñoz, Isabel (Elsevier, 2012-12)

Data from four Spanish basin management authorities were analysed. Chemical and biological data from four Spanish basin management authorities were analysed, focusing on three consecutive years. Aims were to i) determine ...
Application of Probabilistic Neural Networks to microhabitat suitability modelling for adult brown trout (Salmo trutta L.) in Iberian rivers

Muñoz Mas, Rafael; Martinez-Capel, Francisco; Garófano-Gómez, Virginia; Mouton, A.M. (Elsevier, 2014-09)

Probabilistic Neural Networks (PNN) have been tested for the first time in microhabitat suitability modelling for adult brown trout (Salmo trutta L.). The impact of data prevalence on PNN was studied. The PNN were evaluated ...
Assessing and forecasting the impacts of global change on Mediterranean rivers. The SCARCE Consolider project on Iberian basins

Francés, F. (Springer Verlag (Germany), 2012-05)

The Consolider-Ingenio 2010 project SCARCE, with the full title "Assessing and predicting effects on water quantity and quality in Iberian Rivers caused by global change" aims to examine and predict the relevance of global ...
Assessing hydromorphological and floristic patterns along a regulated Mediterranean river: The Serpis River (Spain)

Garófano-Gómez, Virginia; Martinez-Capel, Francisco; Peredo Parada, Matías Manuel; Olaya Marín, Esther Julia; Muñoz Mas, Rafael; Soares Costa, Rui Manuel; Pinar Arenas, José Luis (Asociación Ibérica de Limnología, 2011)

[EN] In the European context, several methodologies have been developed to assess the ecological status and, specifically, the hydromorphological status of running surface waters. Although these methodologies have been ...
Assessment of brown trout habitat suitability in the Jucar River Basin (SPAIN): Comparison of data-driven approaches with fuzzy-logic models and univariate suitability curves

Muñoz Mas, Rafael; Martinez-Capel, Francisco; Schneider, Matthias; Mouton, Ans M. (Elsevier, 2012)

The implementation of the Water Framework Directive implies the determination of an environmental flow (E-flow) in each running water body. In Spain, many of the minimum flow assessments were determined with the physical ...
Data-driven fuzzy habitat suitability models for brown trout in Spanish Mediterranean rivers

Mouton, A.M.; Alcaraz-Hernández, Juan Diego; De Baets, B.; Goethals, , P.L.M; Martinez-Capel, Francisco (Elsevier, 2010-12-30)

[EN] In recent years, fuzzy models have been acknowledged as a suitable approach for species distribution modelling due to their transparency and their ability to incorporate the ecological gradient theory. Specifically, ...
Do Environmental Stream Classifications Support Flow Assessments in Mediterranean Basins?

Belmar, O.; Velasco, J.; Martinez-Capel, Francisco; Peredo Parada, Matías Manuel; Snelder, T. (Springer Verlag (Germany), 2012)

Natural flow regimes are of primary interest in designing environmental flows and therefore essential for water management and planning. The present study discriminated natural hydrologic variation using two different ...
Drivers of Macroinvertebrate Communities in Mediterranean Rivers: A Mesohabitat Approach

Alcaraz-Hernández, Juan Diego; Sánchez-Hernández, Javier; Muñoz-Mas, Rafael; Martinez-Capel, Francisco (MDPI AG, 2024-04)

[EN] We investigated the relationship between benthic macroinvertebrate community attributes (richness, abundance, biodiversity, and climate-specific and resistance forms) and the physical characteristics of distinct ...
Ecological models at fish community and species level to support effective river restoration

Olaya Marín, Esther Julia (Universitat Politècnica de València, 2013-05-15)

RESUMEN Los peces nativos son indicadores de la salud de los ecosistemas acuáticos, y se han convertido en un elemento de calidad clave para evaluar el estado ecológico de los ríos. La comprensión de los factores que ...
Evaluación del hábitat de peces nativos en un tramo del río Júcar bajo diversos escenarios de cambio climático

Santiago Bazan, Frank (Universitat Politècnica de València, 2023-10-23)

[ES] El cambio climático ejerce influencia sobre la hidrosfera y la biosfera en diferentes escalas espaciales, generando modificaciones en los procesos hidrológicos a nivel de cuenca. Estas alteraciones, a su vez, repercuten ...
Habitat suitability modelling at mesohabitat scale and effects of dam operation on the endangered Júcar nase, Parachondrostoma arrigonis (River Cabriel, Spain)

Soares Costa, Rui Manuel; Martinez-Capel, Francisco; Muñoz Mas, Rafael; Alcaraz-Hernández, Juan Diego; Garófano-Gómez, Virginia (Wiley-Blackwell, 2012)

Habitat degradation has reduced the complexity of the Mediterranean streams in Spain and contributed to decreasing the historical range of the endangered Júcar nase, Parachondrostoma arrigonis. This species is endemic to ...
Hydrological classification of natural flow regimes to support environmental flow assessments in intensively regulated Mediterranean rivers, Segura River Basin (Spain)

Belmar, Oscar; Velasco, Josefa; Martinez-Capel, Francisco (Springer Verlag (Germany), 2011-03-26)

Hydrological classification constitutes the first step of a new holistic framework for developing regional environmental flow criteria: the "Ecological Limits of Hydrologic Alteration (ELOHA)". The aim of this study was ...
Modelling critical factors affecting the distribution of the vulnerable endemic Eastern Iberian barbel (Luciobarbus guiraonis) in Mediterranean rivers
