The eruptions of Örӕfajökull 1362 (Iceland) and Lanzarote 1730-36 (Canary Islands) : sulphur emissions and volcanology
This thesis presents new data on the volcanology, erupted volumes, and sulphur emissions of the AD 1362 Örӕfajökull eruption and the AD 1730-36 Lanzarote eruption, and relates these findings to their atmospheric and environmental impacts. The Örӕfajökull eruption was an explosive Plinian event with …

Investigations of the geomorphologic and pedologic system of sedimentary vega deposits from Lanzarote (Canary Islands) supported by luminescence dating – important steps towards their palaeoclimatic interpretation
On Lanzarote (Canary Islands/Spain), sequences similar to loess-palaeosol-sequences from other regions developed in dammed volcanic valleys during the Middle and Late Pleistocene. Based on former investigations, we assumed that these sequences could serve as palaeoclimate archives for the …

Transport and biological activity in chaotic open flows: a numerical study in idealized oceanic flows
… mesoscale activity occurs in the region the Canary Islands in the Atlantic ocean. The residence time of the plankton species in the structures in the wake is determined by the chaotic saddle, the vorticity and other nonlinear effects in the flow. The long residence times in the vicinity of …

The Changing Place of Animals in Post-Franco Spain with particular reference to Bullfighting, Popular Festivities, and Pet-keeping.
… bullfighting (corridas) has been banned in the Canary Islands (1991) and in Catalonia (2010). In addition, numerous municipalities have declared themselves against it. Second, although animals are still widely ‘abused’ and killed (often illegally) in local festivities, many have gradually ceased …

Colonisation and diversification in invertebrates: looking within species on islands to connect pattern and process
… speciation and the assembly of biota. In the Canary Islands, an oceanic island system, the gaps addressed were: (i) the possibility that genomic admixture among multiple founding lineages has featured in the diversification of a very species rich coleopteran genus; and (ii) the lack of …
