Aim Plant specialised metabolites are highly diverse and serve various functions, yet the different forms of phytochemical complexity and their drivers are often not fully understood. In this context, islands provide a valuable opportunity to explore the drivers of phytochemical diversity and its adaptive significance, owing to their unique physical features and markedly different biotic and abiotic pressures compared to the m...
The Barcelona Tissue Bank was established from the merge of two previous multi-tissue banks. Potential donors are screened by Donor Center staff and multi-tissue retrieval is performed by specialized own teams. Tissue processing and preservation is performed in clean room facilities by specialised personnel. After quality control of both donor and all tissues results, the heart valves and vascular segments are stored until med...
The late Pleistocene endemicity increase hypothesis and the origins of diversity in the Canary Islands FloraNARA Subscribed
Aim We explore the idea that most pre‐glacial non‐endemic Canarian flora became endemic to the archipelago by the extinction of its mainland populations during the late Pleistocene glaciations, implying that the extant non‐endemic flora is mostly post‐glacial: the ‘late Pleistocene endemicity increase hypothesis’. Taxon The native flora of the Canarian archipelago. Methods We statistically compare the distributions of 2087 Can...
The in vitro assessment of the toxicity of volatile, oxidisable, redox-cycling compounds: phenols as an exampleNARA Subscribed
Phenols are regarded as highly toxic chemicals. Their effects are difficult to study in in vitro systems because of their ambiguous fate (degradation, auto-oxidation and volatility). In the course of in vitro studies of a series of redox-cycling phenols, we found evidences of cross-contamination in several in vitro high-throughput test systems, in particular by trimethylbenzene-1, 4-diol/trimethylhydroquinone (TMHQ) and 2,6-di...
High rates of land conversion and land use change have vastly increased the proportion of secondary forest in the lowland tropics relative to mature forest. As secondary forests recover following abandonment, nitrogen (N) and phosphorus (P) must be present in sufficient quantities to sustain high rates of net primary production and to replenish the nutrients lost during land use prior to secondary forest establishment. Biogeoc...
Aim The loss of dispersal on islands hypothesis ( LDIH ) posits that wind‐dispersed plants should exhibit reduced dispersal potential, particularly if island populations are old. In this study, we tested this hypothesis using a detailed phylogeographical framework across different geographical scales. Location Mainland and island areas of the Atlantic and Mediterranean regions, including Macaronesia (Canary Islands and Cape Ve...
