La distribution des tuiles estampillées de la VIIIe légion Augusta autour de Mirebeau-sur-Bèze (Côte-d'Or, France)
2011
The 8th Augustan Legion was installed at Mirebeau-sur-Bèze (Côte-d'Or) after 70 AD following the troubles that arose with the Lingons. It remained there until the time of Domitian, a period of roughly twenty years, during which time the soldiers produced tiles stamped with the name of the legion. Analysis of the dispersion of the tiles in the region around Mirebeau shows that they followed the communication routes. Consideration of the contexts in which these tiles were used, their number on each site and the resources necessary to manufacture them reveals that the 8th Legion may have played a significant role in the diffusion and adoption of tiled roofs, a construction technique that was t…
Combining spatial prioritization and expert knowledge facilitates effectiveness of large-scale mire protection process in Finland
2019
Conservation resource allocation involves a complex set of considerations including species, habitats, connectivity, local to global biodiversity objectives, alternative protection and restoration actions, while requiring cost-efficiency and effective implementation. We present a national scale spatial conservation prioritization analysis for complementing the network of protected mires in Finland. We show how spatial prioritization coupled with regional targets and expert knowledge can facilitate structured decision-making. In our application, discussion between experts was structured around the prioritization model enabling integration of quantitative analysis with expert knowledge. The u…
A new Neoplatyura Malloch from Finland (Diptera, Keroplatidae).
2014
The genus Neoplatyura Malloch is globally represented by 50 species, of which four are European species. In this article a new European Neoplatyura from Finland is described. The new species, Neoplatyura noorae Salmela, sp. n. is a dark brown species with tibial bristles arranged in rows. The new species is here reported from seven localities in Finnish Lapland. Based on available data, the new species occurs in mires, especially in calcareous rich fens.
Sciaridae (Diptera) from central Finland: faunistics and taxonomy
2005
Sciaridae (Diptera) from forest and mire habitats from three localities in central Finland were identified. The material consisted of 609 specimens belonging to 106 species. The following species were found as new to Finland: Bradysia subbetuleti, B. submoesta, B. subscabricornis, Corynoptera fera, C. furcifera, C. saetistyla, C. subsedula, Cratyna spiculosa, Leptosciariella helvetica, Lycoriella micria, Pseudolycoriella brunnea, P. nodulosa, Scatopsciara neglecta, Trichosia glabra and Sciara sp. n. (Menzel & Salmela, in prep.) and Ctenosciara exigua sp. n. The latter is described as new to science. Bradysia subbetuleti, Leptosciariella atricha, Leptosciariella tuberculigera and Lycorie…
Verkostonäkökulma ennallistamiskohteiden valinnassa
2013
Verkostonäkökulma korostuu vahvasti luonnonsuojelun suunnittelussa Suomessa ja maailmalla. Suojelualueita ei voi nähdä yksittäisinä eristyneinä alueina, vaan luonnonsuojelualueiden verkosto ja koko ympäröivä maisema ylläpitävät yhdessä tietyn alueen eliölajistoa. Parhaiden alueiden kytkeytyvyyden varmistamista ja verkostojen ylläpitämistä on myös ehdotettu ratkaisuksi biodiversiteetin säilyttämiselle, kun ilmastonmuutos pakottaa lajeja siirtymään uusille asuinalueille. Verkostonäkökulma kannattaa huomioida myös ennallistamiskohteiden valinnassa – mikä ei kuitenkaan ole yksiselitteistä ja helppoa. nonPeerReviewed
L’apiculture dans la plaine des Vosges, Synthèse de l’atelier participatif du 05 avril 2022 à Vittel
2022
National audience; Ce document de synthèse présente les premiers résultats d’un atelier participatif conduit sur trois territoires du département des Vosges en avril 2022. Centrées sur la contribution de l’apiculture à la dynamique d’écologisation du territoire, ces tables rondes avaient pour objectif d’identifier les principaux enjeux de l’apiculture, les espaces propices et problématiques à l’apiculture ainsi que les initiatives favorables à l’activité apicole au sein de chacun de ces territoires. Ces échanges étant par ailleurs couplés à un exercice de spatialisation. Cet atelier participatif a notamment permis de révéler que l’apiculture et l’abeille sont des indicateurs de la qualité é…

The Mathematical Modeling of Ca And Fe Distribution In Peat Layers
2015
Bogs have been formed by an accumulation of peat - a light brown-to-black organic material, built up from partial decomposition of mosses and other bryophytes, sedges, grasses, shrubs, or trees under waterlogged conditions. The total peatlands area in Latvia covers 698 918 ha or 10.7% of the entire territory. Knowledge’s of peat metals content are important for any kind of peat using. Experimental determination of metals in peat is very long and expensive work. Using experimental data mathematical model for calculation of concentrations of metals in different points for different layers can help to very easy and fast to find approximately concentration of metals or trace elements. The resul…
Formalized classification of European fen vegetation at the alliance level
2017
AimsPhytosociological classification of fen vegetation (Scheuchzerio palustris-Caricetea fuscae class) differs among European countries. Here we propose a unified vegetation classification of European fens at the alliance level, provide unequivocal assignment rules for individual vegetation plots, identify diagnostic species of fen alliances, and map their distribution.LocationEurope, western Siberia and SE Greenland.Methods29 049 vegetation-plot records of fens were selected from databases using a list of specialist fen species. Formal definitions of alliances were created using the presence, absence and abundance of Cocktail-based species groups and indicator species. DCA visualized the s…
The role ofSphagnummosses in the methane cycling of a boreal mire
2010
Peatlands are a major natural source of atmospheric methane (CH4). Emissions from Sphagnum-dominated mires are lower than those measured from other mire types. This observation may partly be due to methanotrophic (i.e., methane-consuming) bacteria associated with Sphagnum. Twenty-three of the 41 Sphagnum species in Finland can be found in the peatland at Lakkasuo. To better understand the Sphagnum-methanotroph system, we tested the following hypotheses: (1) all these Sphagnum species support methanotrophic bacteria; (2) water level is the key environmental determinant for differences in methanotrophy across habitats; (3) under dry conditions, Sphagnum species will not host methanotrophic ba…
