; Valle Rodríguez, Jerónimo; Blanco Garrido, Francisco; Narváez, Marta; Delibes Castro, Miguel; Prenda Marín, José (2002)
Los peces continentales son, con toda probabilidad, el grupo de vertebrados peor conocido y con problemas de conservación más acuciantes de cuantos habitan la Península Ibérica. En la franja costera que va desde la duna ... -
Distribución y dieta de la nutria (Lutra Lutra) en un medio heterogéneo del Campo de Gibraltar
Clavero Pineda, Miguel; Rebollo Vega, Antonia José; Valle Rodríguez, Jerónimo; Blanco Garrido, Francisco; Delibes Castro, Miguel; Narváez, Marta; Prenda Marín, José; Barrios, Luis (2002)
En el pasado ampliamente distribuida por todo tipo de ecosistemas acuáticos en la Península Ibérica, la nutria euroasiática ha sufrido durante este siglo un acusado declive, especialmente notorio en sus poblaciones costeras. ... -
Human pressures constrain Eurasian otter occurrence in semiarid Northern Africa
Calzada Samperio, Javier; Clavero Pineda, Miguel; Delibes Castro, Miguel; Fernández, Néstor (Springer, 2022)
Populations inhabiting the periphery of species distribution ranges may experience suboptimal environmental conditions and higher vulnerability to anthropogenic pressures. Disentangling the role of natural and human-related ... -
Hyaenids, felids and canids as bone accumulators: Does the natural history of extant species support zooarchaeological inferences?
Palomares, F.; Ruiz Villar, H.; Morales González, A.; Calzada Samperio, Javier; Román, J.; Rivilla, J.C.; Revilla, E.; Fernández Gil, A.; Delibes Castro, Miguel (Elsevier, 2022)
Mammalian carnivores may be important agents of prehistoric bone accumulations. Taphonomic analyses of bone assemblages used for specific assignment usually include information on feeding, breeding, denning and even ... -
Hydrological stability and otter trophic diversity : a scale-insensitive pattern?
Clavero Pineda, Miguel; Prenda Marín, José; Blanco Garrido, Francisco; Delibes Castro, Miguel (2008)
Two recent works related Eurasian otter (Lutra lutra (L., 1758)) trophic patterns over large areas with the stability of aquatic ecosystems. Higher levels of instability lead to reduced availability and (or) predictability ... -

Blanco Garrido, Francisco; Romero, Rafael; Pedroso, Nuno Miguel; Prenda Marín, José; Santos Reis, Margarida; Narváez, Marta; Ruiz Olmo, Jordi; Sales Luis, Teresa; Clavero Pineda, Miguel; Delibes Castro, Miguel (Sociedad Española para la Conservación y Estudio de los Mamíferos (SECEM), 2008)
A partir de la recopilación de estudios de dieta de la nutria en 200 localidades ibéricas se identificaron los principales gradientes de variación en su composición, tanto a nivel espacial como temporal. Los peces son ... -
The Near Threatened Eurasian otter Lutra lutra in Morocco : no sign of recovery
Delibes Castro, Miguel; Calzada Samperio, Javier; Clavero Pineda, Miguel; Fernández, Néstor; Gutiérrez Expósito, Carlos; Revilla, Eloy; Román, Jacinto (Cambridge University Press, 2012)
Although the Near Threatened Eurasian otter Lutra lutra has been recovering in Europe since the 1980s nothing is known about population trends of the species in northern Africa. Ninety sites was searched for signs of ... -
Seasonal use of coastal resources by otters : comparing sandy and rocky stretches
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. ... -
Trophic diversity of the otter (Lutra lutra L.) in temperate and Mediterranean freshwater habitats
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 ...
