Reyes González, José Manuel de los (Data de defensa: 2021-05-26)
The revolution in biologging and satellite telemetry technologies in the last two decades has led to a new era in seabird research. This thesis brings new insights into the spatial ecology and migration of the Cory’s and ...
Guerreiro Duarte Rivaes da Silva, Ana Sofia (Data de defensa: 2018-12-14)
Migration associated with movements between breeding and wintering areas allow animals to maximize fitness in response to seasonal changes in resources (Dingle 2014). Some of the most incredible migrations in the animal ...
Pérez-Llorca, Marina (Data de defensa: 2021-02-10)
Mediterranean species have to be in constant acclimation to seasonal environmental changes, including variations in water availability, air temperature and solar radiation. Due to global warming, these environmental changes ...
Cuesta Porta, Victor (Data de defensa: 2023-11-13)
[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 ...
Lobato Vila, Irene (Data de defensa: 2021-03-23)
The oak cynipid inquilines (Hymenoptera: Cynipidae: Synergini, Ceroptresini) are a group of specialized endophytophagous microhymenopterans that develop inside galls induced mainly by other cynipids on Fagaceae trees, ...

Superfamily Cynipoidea (Hymenoptera: Apocrita) includes two very different groups of organismes. Macrocynipoids is a paraphyletic group of parasitoids of wood-bearing beetle larvae, characterized by its big size, and with ...
Bellvert Bantí, Adrià (Data de defensa: 2023-11-02)
[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 ...
Sitjà Poch, Cèlia (Data de defensa: 2020-11-05)
The general outline of this thesis was to assess the potential of the Mediterranean water masses to transport deep-sea fauna towards the Atlantic Ocean. By examining the effects that the bathyal water mases moving from the ...
Bastias Álamo, Elliot (Data de defensa: 2018-04-11)
Understanding the dynamics of leaf litter inputs in streams involves assessment of retention, spatial distribution and processing of leaf litter inputs. However, leaf litter dynamics in streams has been mostly studied by ...
Osorio Álvarez, Víctor (Data de defensa: 2024-02-06)
[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 ...
Pintanel Costa, Pol (Data de defensa: 2018-11-26)
Temperature is likely to be one of the most important abiotic factors given how it affects the physiology of the whole organism and as a consequence, it has an essential role in ecology and evolution. However, how the ...
Soria Extremera, Maria (Data de defensa: 2021-05-07)
Temporary rivers (TRs) are dynamic systems that typically shift between flowing, disconnected-pools and dry phases, and represent nearly 50% of the current global river network. Despite TRs support several unique and endemic ...
