Landscape fragmentation and resilience in seagrass meadows / Fragmentación del paisaje y resiliencia en praderas de fanerógamas marinas

Gera, Alessandro (Date of defense: 21-06-2013)
Overall, this thesis is an attempt at approaching seagrass ecosystems from a landscape perspective, with the aim of increasing knowledge about the processes generating patterns at large spatial scales, and understanding ...
Insights into seascape ecology: landscape patterns as drivers in coastal marine ecosystems = Perspectives en l'ecologia del paisatge marí: els patrons del paisatge com a factors de control en els ecosistemes marins costaners

Martínez Ricart, Aurora (Date of defense: 08-04-2016)
Habitats commonly occur as more or less interconnected patches constituting spatial heterogeneous mosaics. Connectivity and interactions among habitats can determine their functioning. Therefore, ecological patterns and ...
Situacions d'anòxia en zones estuàriques sense forçament mareal: una aproximació als balanços producció/consum d'oxigen

De Pedro Puente, Xavier
En aquesta tesi doctoral s'han estudiat les causes de l'aparició de fenòmens hipòxics i anòxics en un sistema costaner estuarià micromareal com la badia dels Alfacs (Mediterrani NW), pel període comprès entre el final dels ...
Scale-dependent factors modulate sea urchin predation in macrophyte communities

Farina, Simone (Date of defense: 10-07-2015)
Many nearshore temperate coastal ecosystems are strongly regulated by top-down control. This is particularly true of shallow macrophyte communities, where habitat structuring is heavily dependent on the ability of predators ...
Tracking environmental change in seagrass meadows: understanding indicator behaviour across space and time

Roca Carceller, Guillem (Date of defense: 06-07-2015)
Nearshore marine ecosystems like seagrass meadows face a wide range of anthropogenic influences, impacting the system at different spatial and temporal scales. Managing these systems in the face of these pressures requires ...
Magnitude of herbivory in "Poseidonia oceanica" (L.) Delile and factors responsible for spatial variation

Prado Villegas, Patricia
La revaluació a gran escala espacial (> de 300 Km) i mitjançant mètodes de quantificació directa, del impacte de l'herbivorisme en els ecosistemes de de 300 Km) i mitjançant mètodes de quantificació directa, del impacte ...
