“…The high degree of clonality differs from results obtained in other vegetatively propagated crops in Fennoscandia. In hops ( Humulus lupulus L.), no identical clones were found when comparing accessions from different Swedish locations (Strese et al 2014). Likewise, in horseradish ( Armoracia rusticana G.…”

Multiplying onion (Allium cepa L. Aggregatum-Group), commonly known as shallot or potato onion, has a long tradition of cultivation in Fennoscandian home gardens. During the last decades, more than 80 accessions, maintained as vegetatively propagated clones, have been gathered from home gardens in all Fennoscandian countries. A genetic analysis showed regional patterns of accessions belonging to the same genetic group. However, accessions belonging to the same genetic group could originate in any of the countries. These results suggested both short- and long-distance exchange of set onions, which was confirmed by several survey responses. Some of the most common genetic groups also resembled different modern varieties. The morphological characterization illustrated that most characters were strongly influenced by environment and set onion properties. The only reliably scorable trait was bulb skin color. Neither our morphological nor genetic results support a division between potato onions and shallots. Instead, naming seems to follow linguistic traditions. An ethnobotanical survey tells of the Fennoscandian multiplying onions as being a crop with reliable harvest, excellent storage ability, and good taste. An increased cultivation of this material on both household and commercial scale should be possible.Electronic supplementary materialThe online version of this article (10.1007/s12231-018-9426-2) contains supplementary material, which is available to authorized users.

What is biological cultural heritage and why should we care about it? An example from Swedish rural landscapes and forests

Citation: What is biological cultural heritage and why should we care about it? An example from Swedish rural landscapes and forests. Nature Conservation 28: 1-32. https://doi.org/10.3897/natureconservation.28.25067 AbstractThere is currently a growing concern that biocultural heritage is threatened in many landscapes. This paper focuses on biological cultural heritage, broadly meaning biological cultural traces that are considered as heritage, but leaving out other aspects of the biocultural heritage concept. An operational definition of biological cultural heritage (BCH) is suggested, based on niche construction theory: "biological manifestations of culture, reflecting indirect or intentional effects, or domesticated landscapes, resulting from historical human niche construction". Some factors that influence recognition of BCH are discussed, using a comparison between Swedish open to semi-open vs. forested landscapes. While the former landscapes are generally associated with biological cultural values, BCH is generally over-looked in forests. Two main reasons for this are suggested: loss of cultural memory and a perception of forests as wilderness. A conclusion is that recognition of BCH is essential for guiding development of biological conservation programmes in forests, irrespective of whether the conservation goal is to focus on culturally impacted forests or to conserve what is considered as close to pristine forests. Furthermore, recognising BCH in forests will promote interest and learning of the history of forests and their values and will be informative for developing conservation programmes for all biota in forests, not only those that historically were favoured by culture. Hence, there is no inherent conflict between preserving relatively untouched forests and those with remaining traces of pre-industrial forest management. The recognition of BCH in forests will inspire and promote further integration of cultural and natural heritage research.

“…The reason why cultivated hop has changed little in the past can thus be attributed to the mainly asexual reproduction by root cuttings, since only female individuals are needed for beer brewing, resulting in very few genetic recombination events over time (Karlsson Strese et al . , , ).…”

Is It Hop? Identifying Hop Fibres in a European Historical Context

et al. 2018

Hop (Humulus lupulus L.) is an ancient perennial crop plant, native to the Northern Hemisphere. The archaeological evidence dates back to at least the sixth century AD in Europe. Hop has been used for beer brewing, in sleeping draughts, as bedding and for antibacterial purposes. Less known is that hop fibres have also been used for textiles and paper. However, it is difficult to distinguish hop from other bast fibres. Here, we present a set of fibre features, which, when found together in an archaeological/historical material within a European context, provide a strong indication that the fibres are hop.
