A Test of the Substitution–Habitat Hypothesis in Amphibians
Martínez-Abraín, Alejandro; Galán, Pedro (Wiley, 2018-05-16)[Abstract] Most examples that support the substitution-habitat hypothesis (human-made habitats act as substitutes of original habitat) deal with birds and mammals. We tested this hypothesis in 14 amphibians by using ... -
Determinants of Eurasian Otter (Lutra Lutra) Diet in a Seasonally Changing Reservoir
Martínez-Abraín, Alejandro; Marí-Mena, Neus; Vizcaíno, Antón; Vierna, Joaquín; Veloy, Carlos; Amboage, Moraima; Guitián-Caamaño, Amanda; Key, Charlie; Vila, Marta (Springer, 2020-03-03)[Abstract] Otter diet in reservoirs is known to experience seasonal changes. We selected a reservoir with a large population of exclusively wintering great cormorants and seasonal changes in stored water volume to test the ... -
Ecological Consequences of Human Depopulation of Rural Areas on Wildlife: A Unifying Perspective
Martínez-Abraín, Alejandro; Jiménez Pérez, Juan; Jiménez, Ignacio; Ferrer, Xavier; Llaneza, Luis; Ferrer Baena, Miguel; Palomero, Guillermo; Ballesteros, Fernando; Galán, Pedro; Oro, Daniel (Elsevier, 2020-11-10)[Abstract] The depopulation of rural areas by humans (or rural exodus) in southern Europe, and the associated abandonment of cropland, had marked ecological consequences on wildlife, which became evident approximately ... -
Ecological Non-equilibrium and Biological Conservation
Oro, Daniel; Martínez-Abraín, Alejandro (Elsevier, 2023-09-08)[Abstract] How to establish efficient conservation actions and policies for the long-term persistence of ecological systems remains a challenge. Conservation biology was born as a discipline of crisis, targeting the recovery ... -
Foreseeing the Future of Posidonia Oceanica Meadows by Accounting for the Past Evolution of the Mediterranean Sea
Martínez-Abraín, Alejandro; Castejón-Silvo, I.; Roiloa, Sergio (Oxford Academic, 2022-12-01)[Abstract] The current warming of the Mediterranean Sea has been forecast to lead to the shrinkage of seagrass meadows. We agree that rising sea temperatures most likely will have immediate negative effects on them because ... -
In Search of a Better Reporting of Scientific Results: A Data Probability Language
Martínez-Abraín, Alejandro (Elsevier, 2022-09-28)[Abstract] A recent paper published in Trends in Ecology and Evolution suggested a new alternative for the reporting of statistical results, using a language based on evidence against the null hypothesis. I agree that the ... -
Increasing Wild Boar Density Explains the Decline of a Montagu’s Harrier Population on a Protected Coastal Wetland
Crespo, Jorge; Jiménez Pérez, Juan; Martínez-Abraín, Alejandro (Museu de Ciències Naturals de Barcelona, 2021-07-19)[Abstract] We studied the rapid decline in the number of breeding pairs (geometric growth rate λ = 0.86; 14 % annual decrease) of a semi–colonial ground–nesting bird of prey, the Montagu's harrier (Circus pygargus), after ... -
Local Prior Information and Mainland Overflow Explain Avian Colonisation in a Major Land-Bridge Island
Martínez-Abraín, Alejandro; Crespo, Jorge; Rebassa, Maties (Wiley, 2023-06-23)[Abstract] Aim: The relative roles of intrinsic and extrinsic factors, and those of local and regional variables, in island colonisation, remain major biogeographical questions. Thus, we analysed avian colonisation records ... -
Pax Romana: ‘Refuge Abandonment’ and Spread of Fearless Behavior in a Reconciling World
Martínez-Abraín, Alejandro; Jiménez Pérez, Juan; Oro, Daniel (Wiley, 2019-02-05)[Abstract] Intense human persecution of wildlife in the past selected for shy individuals that survived in suboptimal refuge habitats. It appears that this long-term conflict is coming to an end in southern Europe, where ... -
Predator-Prey Collapses at the Edge of Predator Distribution: The Case of Clupeids and Common Guillemots (Uria aalge) in NW Iberia
Martínez-Abraín, Alejandro; Santidrián Tomillo, Pilar; Mouriño, Jorge; Rodríguez Silvar, Juan; Bermejo Díaz de Rábago, Andrés (CSIC, 2023-02-23)[Abstract] The spatial structuring of seabird populations makes individual colonies very dependent on regional factors. That is especially the case in small edge populations located far from large colonies. We analysed ... -
Stick Supply to Nests by Cliff-Nesting Raptors as an Evolutionary Load of Past Tree-Nesting
Martínez-Abraín, Alejandro; Jiménez Pérez, Juan (Queen's University, 2019)[Abstract] The supply of sticks to cliff nests by many European raptors has been explained only as a functional means of decreasing ectoparasite loads in nests and for signalling nest occupancy. We provide here a historical ... -
The Selection of Anthropogenic Habitat by Wildlife as an Ecological Consequence of Rural Exodus: Empirical Examples From Spain
Martínez-Abraín, Alejandro; Ferrer, Xavier; Jiménez Pérez, Juan; Fernández–Calvo, I. C. (Museu de Ciències Naturals de Barcelona, 2021-06-18)[Abstract] The increasing urbanization of the landscape is a major component of global change worldwide. However, it is puzzling that wildlife is selecting anthropogenic habitats despite the availability of apparently ... -
Translocation in Relict Shy-Selected Animal Populations: Program Success Versus Prevention of Wildlife-Human Conflict
Martínez-Abraín, Alejandro; Quevedo de Anta, Mario; Serrano, David (Elsevier, 2022-03-11)[Abstract] Past human persecution of wildlife has acted as a major selection agent shaping many animal features including behaviour. A major component of behaviour with diverse consequences for conservation is the ... -
Translocation of Bolder Birds Could Provide Benefits to Mediterranean Osprey Populations Under Current Conditions of High Human Frequentation in Natural Areas
Martínez-Abraín, Alejandro (Elsevier, 2022-06-24)
