Let’s pluck the daisy: dissection as a tool to explore the diversity of Asteraceae capitula.
Asteraceae, the daisy family, are one of the most diverse families of angiosperms and are predominant in many ecosystems, including grasslands, deserts, savannas and high-elevation mountains. They are characterized by a peculiar inflorescence, the capitulum, which mimics a flower, but is actually made up of many tightly grouped florets. The...Fu, Lin ; Palazzesi, Luis ; Pellicer, Jaume ; Balant, Manica ; Christenhusz, Maarten J M …

The correlation of phylogenetics, elevation and ploidy on the incidence of apomixis in Asteraceae in the European Alps.
Asexual reproduction has often been regarded as an evolutionary dead end, but asexual lineages (most notably those that are apomictic) are present in several angiosperm families and often comprise a large number of taxa, both widespread and endemic. Investigating correlations between genetic, environmental and taxonomic factors and the incidence of... -

Automated video monitoring of insect pollinators in the field.
Ecosystems are at increasing risk from the global pollination crisis. Gaining better knowledge about pollinators and their interactions with plants is an urgent need. However, conventional methods of manually recording pollinator activity in the field can be time- and cost-consuming in terms of labour. Field-deployable video recording systems have become...Pegoraro, Luca ; Hidalgo, Oriane ; Leitch, Ilia J. ; Pellicer, Jaume ; Barlow, Sarah E.

Shift in flowering time allows diploid and autotetraploid Anacamptis pyramidalis (Orchidaceae) to coexist by reducing competition for pollinators
How autopolyploids establish when competing with diploid progenitors is still poorly understood. Here, we investigate the effects of morphological and phenological divergence on the reproductive success of co-occurring diploid and autotetraploid individuals of Anacamptis pyramidalis to disentangle the mechanisms allowing their c-oexistence. We estimated reproductive success in terms of absolute...
