Estudio de los mesohábitats acuáticos para parachondrostoma arrigonis y squalius valentinus en la reserva de la biosfera del Valle del Cabriel

Bolós Aguilar, Miguel Ángel (Universitat Politècnica de València, 2024-10-04)

[ES] El objetivo de este trabajo de final de grado consiste en realizar una cartografía de hábitats y el análisis de la abundancia de dos especies de peces, en 21 tramos de estudio del río Cabriel. Dichos tramos fueron ...
Generalized additive models to predict adult and young brown trout (Salmo trutta Linnaeus, 1758) densities in Mediterranean rivers

Alcaraz-Hernández, Juan Diego; Muñoz Mas, Rafael; Martinez-Capel, Francisco; Garófano-Gómez, Virginia; Vezza, Paolo (Wiley: 12 months, 2016-02)

Habitat suitability models (HSM) are concerned with the abundance or distribution of species as a consequence of interactions with the physical environment. Generalized Additive Models (GAMs) were used to model brown trout ...
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 influences on aquatic communities at the mesohabitat scale in high Andean streams of southern Ecuador

Vimos-Lojano, Diego; Martinez-Capel, Francisco; Hampel, Henrietta; Vázquez, Raúl F. (John Wiley & Sons, 2019-01)

[EN] This study assessed the effects of hydrological events on aquatic communities at the mesohabitat scale (pool, run, and riffle) in the high Andean region. Four headwater sites located in the Zhurucay microcatchment ...
Mesohabitat heterogeneity in four mediterranean streams of the Jucar river basin (Eastern Spain)

Alcaraz-Hernández, Juan Diego; Martinez-Capel, Francisco; Peredo Parada, Matías Manuel; Hernández Mascarell, Aina Berta (Asociación Ibérica de Limnología, 2011)

[EN] The hydromorphological units or mesohabitats of the headwaters of four Mediterranean streams were studied by classifying them according to their length, width, average and maximum depth, percentage of substrate and ...
Modeling fish species distributions with machine learning techniques

Garcia Ventura, Cristian (Universitat Politècnica de València, 2022-11-02)

[ES] Los sistemas naturales de agua dulce se ven ampliamente afectados por las presiones hidromorfológicas, las cuales derivan principalmente de la acción humana en el medio ambiente y de el consumo excesivo de los recursos ...
Random forests to evaluate interspecific interactions in fish distribution models

Vezza, Paolo; Muñoz Mas, Rafael; Martinez-Capel, Francisco; Mouton, A. (Elsevier, 2015-05)

[EN] Previous research indicated that high predictive performance in species distribution modelling can be obtained by combining both biotic and abiotic habitat variables. However, models developed for fish often only ...
Relaciones entre densidades y biomasas de Salmo trutta fario y mediciones del mesohabitat en tramos trucheros de la Comunidad Valenciana

Alcaraz-Hernández, Juan Diego; Martinez-Capel, Francisco; Peredo Parada, Matías Manuel; Hernández Mascarell, Aina Berta (Asociación Ibérica de Limnología, 2007)

[EN] In the year 2003, populations of Salmo trutta fario were studied in the Valencian rivers. Habitat conditions were also studied along the successive hydro-morphological units in 300 m long reaches, along with geographic ...
