Conservation of the Giant Freshwater Pearl Mussel (Pseudunio auricularius = Margaritifera auricularia Spengler, 1793) in Spain
2023
Las almejas de agua dulce o náyades son uno de los grupos faunísticos más amenazados del planeta. Entre ellos, la almeja gigante del Ebro o náyade auriculada (Pseudunio auricularius, Spengler 1793) es el bivalvo unionido más amenazado de Europa, y la población de la cuenca del río Ebro en España se encuentra en una situación crítica. El objetivo de esta tesis es aumentar el conocimiento científico del estado de conservación actual de la especie en España con el fin de aplicar acciones de gestión significativas para reducir su riesgo de extinción. El descenso de las poblaciones de náyades (Orden Unionida) en la cuenca del Ebro es generalizado, pero la situación en los canales asociados es cr…
The freedom of conscience and religion of particularly dangerous offenders (Article 88a and 88b of the Executive Penal Code)
2020
Wolność sumienia i religii należy do katalogu podstawowych praw człowieka. Jednak realizacja związanych z tym uprawnień w przypadku skazanych niebezpiecznych została ograniczona przez konieczność ich wykonywania w warunkach oddziału, w pomieszczeniach o wysokim stopniu zabezpieczenia ochronnego. Również kontakt skazanych niebezpiecznych z innymi osobami (w tym także duchownym) ograniczono w sposób maksymalny. Ustawodawca uznał, że stosowanie ograniczeń w realizacji uprawnień sprawców szczególnie niebezpiecznych jest potrzebne do zapewnienia bezpieczeństwa zakładu karnego. Jednak wprowadzone obostrzenia można także uznać za element nieludzkiego traktowania, zwłaszcza wówczas, gdy ich stosowa…

Effect of substrate particle size on burrowing of the juvenile freshwater pearl mussel Margaritifera margaritifera
2021
AbstractJuveniles of the endangered freshwater pearl mussel (FPM,Margaritifera margaritifera) live burrowed in stream substrate for the first years of their life. Fine sediments block water exchange within substrate and may cause juvenile mortality and recruitment failure. To better understand the connection between success of juvenile FPM and substrate particle size, it would be important to understand behavioural responses of FPM to varying substrate sizes at this critical life stage. We placed newly detached FPM juveniles in a 7-mm layer of sieved sand sorted into five sizes (< 120, 120–200, 200–250, 250–500 and 500–650 µm) each with 10 replicate dishes, 10 juveniles per dish, with bu…
Who threatens who? Natural hybridization between Lotus dorycnium and the island endemic Lotus fulgurans (Fabaceae)
2010
In contrast to its creative role in plant evolution, hybridization may be a cause for concern in efforts to preserve rare and endangered species. Threats can be more acute when population sizes are unequal and when barriers to introgression are weak. Lotus fulgurans is an endangered Balearic Islands endemic shrub related to the widespread Mediterranean species Lotus dorycnium. Both species are morphologically distinct when they grow together. However, morphologically intermediate individuals have been observed on the island of Minorca, in a single, narrowly localized, and apparently stable hybrid zone. Morphological and molecular markers suggest that gene flow between these two Lotus specie…
Biogeography of the smooth snake (Coronella austriaca): origin and conservation of the northernmost population
2014
Understanding historical range expansions and population demography can be crucial for the conservation and management of endangered species. In doing so, valuable information can be obtained regarding, for example, the identification of isolated populations, associations to particular habitats and distribution range shifts. As poikilotherms, snakes are vulnerable to environmental changes that can greatly shape their distribution ranges. Here we used mitochondrial data to elucidate the origin of the smooth snake population in Aland island, which is the northernmost location where the species is found. In Aland, we used mitochondrial and microsatellite data to fine-map its spatial genetic st…
Resembling a Viper: Implications of Mimicry for Conservation of the Endangered Smooth Snake
2014
The phenomenon of Batesian mimicry, where a palatable animal gains protection against predation by resembling an unpalatable model, has been a core interest of evolutionary biologists for 150 years. An extensive range of studies has focused on revealing mechanistic aspects of mimicry (shared education and generalization of predators) and the evolutionary dynamics of mimicry systems (co-operation vs. conflict) and revealed that protective mimicry is widespread and is important for individual fitness. However, according to our knowledge, there are no case studies where mimicry theories have been applied to conservation of mimetic species. Theoretically, mimicry affects, for example, frequency…
