  • How, not if, is the question mycologists should be asking about DNA-based typification
  • 2023

    • Fungal metabarcoding of substrates such as soil, wood, and water is uncovering an unprecedented number of fungal species that do not seem to produce tangible morphological structures and that defy our best attempts at cultivation, thus falling outside the scope of the International Code of Nomenclature for algae, fungi, and plants. The present study uses the new, ninth release of the species hypotheses of the UNITE database to show that species discovery through environmental sequencing vastly outpaces traditional, Sanger sequencing-based efforts in a strongly increasing trend over the last five years. Our findings chal-lenge the present stance of some in the mycological community - that the current situation is satisfactory and that no change is needed to "the code" - and suggest that we should be discussing not whether to allow DNA-based descriptions (typifications) of species and by extension higher ranks of fungi, but what the precise requirements for such DNA-based typifications should be. We submit a tentative list of such criteria for further discussion. The present authors hope for a revitalized and deepened discussion on DNA-based typification, because to us it seems harmful and counter-productive to intentionally deny the overwhelming majority of extant fungi a formal standing under the International Code of Nomenclature for algae, fungi, and plants.

  • Fewer people would help preserve biodiversity: A response to Hughes et al. (2023)
  • 2023
  • Ingår i: Biological Conservation. - 0006-3207. ; 282
  • Tidskriftsartikel (refereegranskat)abstract
    • “Smaller human populations are neither a necessary nor sufficient condition for biodiversity conservation,” according to Alice Hughes and colleagues. We agree that reducing human numbers is not sufficient for preserving biodiversity; whether it’s necessary depends on how high we set the bar for successful conservation. If we hope to preserve robust populations of most of the world’s remaining wild species and their habitats, the evidence suggests human populations will have to be considerably reduced.

  • Collection, cultivation and processing of medical plants, herbs and spices in the Balaton Ecomuseum – herbal medicine as intangible cultural heritage
  • 2020
  • Ingår i: Ecocycles. - : Ecocycles. - 2416-2140. ; 6:1, s. 52-87
  • Tidskriftsartikel (refereegranskat)abstract
    • The Balaton Ecomuseum, which is being continuously developed since 2017, will have a holistic approach, where the objectives of the ecomuseum embrace the whole cultural landscape of Lake Balaton as one unit with several thematic routes in one system and shall not be restricted to one particular subject area or a part of local heritage. One of these thematic routes is the recently developingHerbs and Spices Network, led by Zánka Herb Valley Visitor and Training Centre based on the collection, cultivation and processing of medicinal plants, herbs and spices. The place of herbs and spices in the diet needs to be considered in reviewing health benefits, including definitions of the food category and the way in which benefits might be viewed, and therefore researched.Here we describe the already established system of the Zánka Herb Valley Visitor and Training Centre, the potential of the Balaton Region in the development of herbal medicine illustrated by the scientific presentation of the 30 most collected herbs in the region and examples of other herbal centres, which are intended to become a part of the network. Herbalmedicine, as an important part of the intangible cultural heritage, with hundreds of years old recipes for herbal concoctionshas been known since ancient times before science related to modern medicine developed and continues to be used for generationsuntil now. Furthermore, the medical effects of many agricultural crops should be better understood, such as the grapevine, which is being investigated for its medical compounds or the medicinal properties of other fruits and vegetables not sufficiently known to the general public. In this study we present a new system of the culture and interactive education of the collection, cultivation and use of medicinal plants, herbs and spices applying a learning by doing approach and a network embracing the whole area of the Balaton Ecomuseum.

  • Quantifying landscape change during the last two centuries in Bialowieza Primeval Forest
  • 2013
  • Ingår i: Applied Vegetation Science. - 1402-2001 .- 1654-109X. ; 16:2, s. 217-226
  • Tidskriftsartikel (refereegranskat)abstract
    • QuestionWhat changes in character and extent of land use have occurred during the last 200yr in the Biaowiea Primeval Forest (BPF)? Are the landscape transformations described from the multi-temporal analysis of historical maps coherent with vegetation changes expressed by the previous palynological analyses?LocationBiaowiea Primeval Forest, PolishBelarusian border. MethodsWe used five historical maps (from 1793 to 1936) and one digital land-use map (19992000) to quantify the landscape changes. Land-use types according to historical maps were digitized and georeferenced. The maps were then used for both comparing the extent of cover types in each time step and analysing the nature of change through transition matrices. The sequence of changes concerning the proportion of land-use types was then compared with classes of pollen, which were assumed to represent corresponding vegetation types. ResultsMost of the area (>70%) has been continuously covered with forest. In the period between 1793 and 1830, the forest declined, being the main donor to agricultural land and villages. In the 20th century, the trend was reversed. We found a significant correlation between the percentage of the main vegetation types derived from historical maps and the corresponding vegetation types, as indicated by pollen, with a mean time lag of 20yr. ConclusionThe BPF landscape has been quite stable throughout the last 200yr, mainly due to the high continuity of forest cover. The results obtained from landscape analysis based on maps are coherent with pollen data collected in the same area.

  • Predicting island beetle faunas by their climate ranges : the tabula rasa/refugia theory in the North Atlantic
  • 2015
  • Ingår i: Journal of Biogeography. - : Wiley-Blackwell. - 0305-0270 .- 1365-2699. ; 42:11, s. 2031-2048
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: This paper addresses two opposing theories put forward for the origins of the beetle fauna of the North Atlantic islands. The first is that the biota of the isolated oceanic islands of the Faroes, Iceland and Greenland immigrated across a Palaeogene–Neogene land bridge from Europe, and survived Pleistocene glaciations in ameliorated refugia. The second argues for a tabula rasa in which the biota of the islands was exterminated during glaciations and is Holocene in origin. The crux of these theories lies in the ability of the flora and fauna to survive in a range of environmental extremes. This paper sets out to assess the viability of the refugia hypothesis using the climatic tolerances of one aspect of the biota: the beetle fauna. Location: The paper focuses on Iceland, the Faroe Islands and Greenland. Methods: The known temperature requirements of the recorded beetle faunas of the North Atlantic islands were compared with published proxy climate reconstructions for successive climate periods since the severing of a North Atlantic land bridge. We used the MCR (mutual climatic range) method available in the open access BugsCEP database software. Results: We show that most of the MCR faunas of the North Atlantic islands could not have survived in situ since the Palaeogene–Neogene, and are likely to have been exterminated by the Pleistocene glaciations. Main conclusions: The discrepancy between the climatic tolerances of the North Atlantic beetle fauna and the estimated climatic regimes since the severing of a land bridge strongly support the tabula rasa theory and suggests that the North Atlantic coleopteran fauna is Holocene in origin.

  • The Strategic Environmental Archaeology Database : a resource for international, multiproxy and transdisciplinary studies of environmental and climatic change
  • 2015
  • Konferensbidrag (refereegranskat)abstract
    • Climate and environmental change are global challenges which require global data and infrastructure to investigate. These challenges also require a multi-proxy approach, integrating evidence from Quaternary science and archaeology with information from studies on modern ecology and physical processes among other disciplines. The Strategic Environmental Archaeology Database (SEAD http://www.sead.se) is a Swedish based international research e-infrastructure for storing, managing, analysing and disseminating palaeoenvironmental data from an almost unlimited number of analysis methods. The system currently makes available raw data from over 1500 sites (>5300 datasets) and the analysis of Quaternary fossil insects, plant macrofossils, pollen, geochemistry and sediment physical properties, dendrochronology and wood anatomy, ceramic geochemistry and bones, along with numerous dating methods. This capacity will be expanded in the near future to include isotopes, multi-spectral and archaeo-metalurgical data. SEAD also includes expandable climate and environment calibration datasets, a complete bibliography and extensive metadata and services for linking these data to other resources. All data is available as Open Access through http://qsead.sead.se and downloadable software. SEAD is maintained and managed at the Environmental Archaeology Lab and HUMlab at Umea University, Sweden. Development and data ingestion is progressing in cooperation with The Laboratory for Ceramic Research and the National Laboratory for Wood Anatomy and Dendrochronology at Lund University, Sweden, the Archaeological Research Laboratory, Stockholm University, the Geoarchaeological Laboratory, Swedish National Historical Museums Agency and several international partners and research projects. Current plans include expanding its capacity to serve as a data source for any system and integration with the Swedish National Heritage Board's information systems. SEAD is partnered with the Neotoma palaeoecology database (http://www.neotomadb.org) and a new initiative for building cyberinfrastructure for transdisciplinary research and visualization of the long-term human ecodynamics of the North Atlantic funded by the National Science Foundation (NSF).

  • Mapping and Evaluating Marine Protected Areas and Ecosystem Services: A Transdisciplinary Delphi Forecasting Process Framework
  • 2021
  • Ingår i: Frontiers in Ecology and Evolution. - : Frontiers Media SA. - 2296-701X. ; 9
  • Tidskriftsartikel (refereegranskat)abstract
    • Marine Protected Areas (MPAs) are an important tool for management and conservation and play an increasingly recognised role in societal and human well-being. However, the assessment of MPAs often lacks a simultaneous consideration of ecological and socio-economic outcomes, and this can lead to misconceptions on the effectiveness of MPAs. In this perspective, we present a transdisciplinary approach based on the Delphi method for mapping and evaluating Marine Protected Areas for their ability to protect biodiversity while providing Ecosystem Services (ES) and related human well-being benefits – i.e., the ecosystem outputs from which people benefit. We highlight the need to include the human dimensions of marine protection in such assessments, given that the effectiveness of MPAs over time is conditional on the social, cultural and institutional contexts in which MPAs evolve. Our approach supports Ecosystem-Based Management and highlights the importance of MPAs in achieving restoration, conservation, and sustainable development objectives in relation to EU Directives such as the Marine Strategy Framework Directive (MSFD), the Maritime Spatial Planning Directive (MSPD), and the Common Fisheries Policy (CFP).
