    Assessing the influence of the atmospheric oscillations on pelagic and highly migratory sharks bycatches from Spanish Mediterranean Sea, a meta-analytic approach
    (Universidad de Murcia. Facultad de Biología, 2015) Báez, José Carlos
    Evaluación de la influencia de las oscilaciones atmosféricas sobre las capturas accesorias de tiburones pelágicos y altamente migratorios desde el Mediterráneo español, un enfoque metaanalítico El objetivo principal del presente estudio fue analizar el efecto de las oscilaciones atmosféricas sobre los patrones de descarga de los tiburones pelágicos capturados de forma accesoria en palangre de superficie (fundamentalmente tintoreras, marrajos, y tiburones zorros) desde el Mediterráneo español, utilizando un enfoque meta-analítico. El objetivo final es conocer la respuesta de los tiburones altamente migratorios a los fenómenos climáticos de gran escala, y su posible relación con el efecto del calentamiento global. Se utilizaron dos fuentes de datos diferentes, ambas de áreas geográficas diferentes: mar de Alborán y mar Balear. Los resultados indican que la abundancia local de tiburones pelágicos podría estar mediada por la oscilación ártica. P

    Evaluating drivers of vulnerability to climate change: a guide for insect conservation strategies
    (Wiley, 2012) Arribas, Paula; Abellán, Pedro; Velasco, Josefa; Bilton, David T.; MIillán, Andrés; Ecología e Hidrología
    Ongoing global climate change presents serious challenges in conservation biology, forcing us to revisit previous tools and principles based on how species may respond to novel climatic conditions. There is currently a major gap between predictions of species vulnerability and management strategies, despite the fact that linking these areas is fundamental for future biodiversity conservation. Herein, we evaluate what drives vulnerability to climate change in three Iberian endemic water beetles, representing three independent colonizations of the same habitat, employing comparative thermal physiology, species distribution models and estimations of species dispersal capacity. We derive conservation strategies for each species based on their differential capacity to persist and/or potential to shift their ranges in response to global warming. We demonstrate that species may be affected by climatic warming in very different ways, despite having broadly similar ecological and biogeographical traits. The proposed framework provides an effective complement to traditional species vulnerability assessments, and could aid the development of more effective conservation strategies in the face of global warming.

    First record of winter pregnant males of two pipefish species in a Mediterranean coastal lagoon
    (Wiley, 2025-08-22) Guerrero Gómez, Adrián; Zamora López, Antonio; Herrero Reyes, Antonio Andrés; Oliva Paterna, Francisco José; Madrid Ruiz, Jorge; Álvarez-Navarro, Víctor M.; Peñalver Miras, Rocío; Torralva Forero, María del Mar; Zoología y Antropología Física; Facultades de la UMU::Facultad de Biología
    Syngnathus abaster Risso, 1827 and Syngnathus typhle L., 1758 are key components of fish assemblages in European transitional waters, with well-documented reproductive cycles typically occurring from spring to autumn. However, recent warming trends in the western Mediterranean has raised questions about potential shifts in their breeding phenology. In January 2025, three pregnant S. abaster males and one S. typhle male were detected in the Mar Menor Coastal lagoon (western Mediterranean), representing the first recorded winter breeding event for both species. The size structure of S. abaster in winter 2025 also contrasted with colder winters, further supporting this interpretation. These findings may reflect a response to recent thermal anomalies and highlight the phenological plasticity of these species. To our knowledge, this is the first indication of potential phenological shifts in syngnathids from transitional waters, with implications for understanding how climate change may influence their reproductive dynamics.
