Efectes de l'associació de varietats de blat sobre l’abundància d’espècies arvenses, de pugons i la producció en cultius ecològics
[cat] La major part de la producció ecològica mundial de blat prové de conreus de varietats modernes en règim de monocultiu. La sembra de varietats tradicionals és poc comuna per la baixa disponibilitat en el mercat i ...
El cultiu del blat a l’ambient mediterrani davant la crisi climàtica: Perspectives geogràfiques des de la teledetecció i l’ecofisiologia
[cat] OBJECTIUS: L’objectiu general de la tesi és emprar dades de teledetecció i sistemes d’informació geogràfica per estimar i comprendre el rendiment i qualitat de varietats de blat mediterrani tot considerant els ...
Ecoacústica del gall fer Tetrao urogallus al Pirineu català
[cat] La comunicació animal té lloc en ambients amb un paisatge sonor específic, compost pels sons generats pels éssers vius (biofonia), els sons d'origen antròpic com el de la maquinària o els cotxes (antropofonia) i el ...
Species interactions, ecosystem functioning and the resilience of marine vegetated ecosystems in a global change era
[eng] Human domination of Earth’s Systems is transforming life at a planetary scale. A plethora of anthropogenic pressures disrupt environmental conditions, degrading ecosystem functioning and posing unprecedented threats ...
Ecological segregation in allochronic populations of storm-petrels
[eng] Divergence in reproductive timing, known as allochrony, is an evolutionary process that in some cases has led to sympatric speciation. However, the mechanisms that could drive the existence of allochrony (e.g., ...
Spatial Ecology of the Endangered Egyptian Vulture: from Distribution and Movement to Biological Conservation
[eng] The current rampant loss of biodiversity is known to be affecting human well-being the world over. Sustainability has become the global go-to solution to ensure the balance between economic growth, social well-being ...
Ecological patterns of Antarctic benthic communities and the biodiversity they harbour
[eng] The exploration of marine environments, especially the deep sea, has been an ongoing effort. With the majority of Earth’s surface covered by oceans, the invention of SCUBA and subsequent deep-sea expeditions has ...
Unravelling seabird-fishery dynamics through bird-borne technologies
[eng] Seabirds and fisheries share the same fishing resources and grounds, resulting in their inevitable interaction, with significant conservation implications for the firsts. Seabirds scavenging on fishery waste modify ...
Facing Global Change: Impacts of drying and human pressures on invertebrate diversity and organic matter processing in a Mediterranean stream network
[eng] Intermittent rivers and ephemeral streams (IRES) currently constitute half of the global river network, occurring ubiquitously. Characterised by natural and periodic cessations of flow, IRES are proliferating due to ...
Gestió, recerca i ciutadania en l’estudi de l’estat dels rius mediterranis. La importància de l’educació ambiental, la ciència ciutadana i la participació en la gestió dels ecosistemes fluvials
[cat] Aquesta tesi doctoral sorgeix de l'empremta deixada pel grup de recerca FEHM, liderat pel Dr. Prat, amb més de quatre dècades d'activitat dedicada a la investigació en ecologia aquàtica des de la Facultat de Biologia ...
All for one: organ and tissue-specific responses in the hormonal modulation of plant (a)biotic interactions
[eng] Plants are not isolated organisms; instead, they constantly interact with the microorganisms in their environment, forming a holobiont that consists of the plants themselves and their entire microbiome. This holobiont ...
Aplicación de biocarbón en la agricultura: Mejoramiento de la calidad de suelos mediante el uso de diferentes combinaciones de biocarbón y enmiendas orgánicas y su efecto sobre la nutrición y producción agrícola
[spa] El suelo, un recurso no renovable y esencial para el desarrollo de la vida, se ve afectado por los sistemas de producción de cultivos que provocan su degradación. El biocarbón, un producto rico en carbono obtenido ...
Genetic variability of minnows and loaches in rivers and high mountain lakes from the Pyrenees and Italian Alps
[eng] The invasion of alien species is a major global threat to ecosystems, with significant impacts, especially on freshwater ecosystems. The species diversity in freshwater ecosystems has significantly declined worldwide, ...
Biological mechanisms underlying psychosocial stress response: The consequences of prenatal maternal distress and childhood maltreatment on the endocrine and immune systems
[eng] During critical periods of development, psychosocial stress experiences may alter key neural networks of the human brain, with long-lasting effects on behavior and mental health. However, the specific biological ...
The role of non-native fish on littoral macroinvertebrates of Pyrenean high mountain lakes
[eng] High mountain freshwater ecosystems, such as Pyrenean lakes, are distinguished by their unique ecological characteristics, which encompass their near-pristine undisturbed state, unique biodiversity, and their role ...
Effects of dam decommissioning on carbon cycling in reservoirs. Case study of the Enobieta Reservoir, N Iberian Peninsula
[eng] The overall objective of this thesis is to explore the effects of DD on C cycling in reservoirs because there are many dams under removal and many more predicted in the near future. To answer this question, we conducted ...
Testing the hypothesis of adaptive radiation and its eco-phenotypic implications
[eng] Without a shadow of a doubt, adaptive radiation processes have played a major role in our current understanding of how species evolved on our planet. Since the original proposal of the theory of evolution by natural ...
Invasiones biológicas en ambientes marinos tropicales: El caso del pez león (Pterois volitans)
[spa] El pez león (Pterois volitans) inició una propagación sin precedentes en rapidez y magnitud a partir de Florida, Estados Unidos de América, y quizás las Bahamas hace más de dos décadas. Actualmente se ha establecido ...
Systematics of Nearctic and Neotropical Oak Gall Wasps (Hymenoptera: Cynipidae: Cynipini), with a focus on specific genera in the fauna of Mexico
[eng] The oak gall wasps (Hymenoptera: Cynipidae: Cynipini) are a group of specialized endophytophagous microhymenopterans that induce galls on Fagaceae trees, principally oaks (Quercus L.). The systematics of this tribe ...
Patrones de comportamiento y perfiles de personalidad en el delfín mular (Tursiops truncatus), y su utilidad como herramienta de manejo en cautividad
