Stingless bees (Hymenoptera; Apidae; Meliponini), with a biodiversity of 605 species, harvest and transport corbicula pollen to the nest, like , but process and store the pollen in cerumen pots instead of beeswax combs. Therefore, the meliponine pollen processed in the nest was named pot-pollen instead of bee bread. Pot-pollen has nutraceutical properties for bees and humans; it is a natural medicinal food supplement with applications in health, food science, and technology, and pharmaceutical developments are promising.

The biodiversity of Ecuadorian stingless bees is almost 200 species. Traditional pot-honey harvest in Ecuador is mostly done from nests of the three genera selected here Moure, 1943, Illiger, 1806, and Moure, 1942. The 20 pot-honey samples collected from cerumen pots and three ethnic honeys "abeja de tierra", "bermejo", and "cushillomishki" were analyzed for qualitative and quantitative targeted H-NMR honey profiling, and for the Honey Authenticity Test by Interphase Emulsion (HATIE).

Polyploidy is one of the major forces of plant evolution and widespread mixed-ploidy species offer an opportunity to evaluate its significance. We therefore selected the cosmopolitan species Urtica dioica (stinging nettle), examined its cytogeography and pattern of absolute genome size, and assessed correlations with bioclimatic and ecogeographic data (latitude, longitude, elevation). We evaluated variation in ploidy level using an extensive dataset of 7012 samples from 1317 populations covering most of the species' distribution area.

Crop cultivation can lead to genetic swamping of indigenous species and thus pose a serious threat for biodiversity. The rare Eurasian tetraploid shrub (ground cherry) is suspected of hybridizing with cultivated allochthonous tetraploid and autochthonous diploid . Three taxa (447 individuals of , 43 of and 73 of ) and their hybrids (198 individuals) were evaluated using analysis of absolute genome size/ploidy level and multivariate morphometrics.

We reconstructed the historical pattern of postglacial biogeographic range expansion of the boreal tree species Alnus incana in Europe. To assess population genetic structure and diversity, we performed a combined analysis of nuclear microsatellite loci and chloroplast DNA sequences (65 populations, 1004 individuals). Analysis of haplotype and microsatellite diversity revealed that southeastern refugial populations situated in the Carpathians and the Balkan Peninsula did not spread north and cannot be considered as important source populations for postglacial recolonization of Europe; populations in Eastern Europe did not establish Fennoscandian populations; populations in Fennoscandia and Eastern Europe have no unique genetic cluster, but represent a mix with a predominant cluster typical for Central Europe; and that colonization of Fennoscandia and Eastern Europe took place from Central Europe.

  • This study investigates the distribution and origins of different cytotypes of the plant Alnus glutinosa across Europe, North Africa, and western Asia, highlighting the significance of polyploidy in plant biology.
  • Using flow cytometry, microsatellite analysis, and species distribution modeling, the research identifies distinct clusters of tetraploid populations in the Iberian Peninsula and Dinaric Alps, both likely derived from autopolyploid processes rather than hybridization with A. incana.
  • The findings suggest that the newly identified tetraploid populations have remained separate from those in central and northern Europe post-glacial retreat, indicating that these regions may not have acted as effective refugia for the

  • Genetic admixture plays a key role in species expansion by allowing for the selection of beneficial genotypes suited for changing climates, yet comprehensive studies on this phenomenon have been lacking.
  • A study on Alnus glutinosa's postglacial history identified multiple southern refuges and three main directions of expansion: north from Iberia, from the Apennines to the Alps, and from the Balkans to Northern Europe.
  • The findings suggest that rather than solely originating from the Carpathians, European populations show significant genetic diversity from multiple contact zones, while Mediterranean populations face higher extinction risks due to limited genetic mixing in the face of climate change.

The Hieracium and Pilosella (Lactuceae, Asteraceae) genera of closely related hawkweeds contain species with two different modes of gametophytic apomixis (asexual seed formation). Both genera contain polyploid species, and in wild populations, sexual and apomictic species co-exist. Apomixis is known to co-exist with sexuality in apomictic Pilosella individuals, however, apomictic Hieracium have been regarded as obligate apomicts.
