Introduction. Following on from work the European bryophyte Red List, taxonomically and nomenclaturally updated spreadsheets used for that project have been expanded into a new checklist bryophytes of Europe.Methods. A steering group ten bryologists was convened, over course year, were compared with previous checklists, all changes noted. Recent literature searched extensively. taxonomic system agreed, advice expertise many sought.Key results. bryophytes, comprising hornworts, liverworts...
SummaryGrotius has a rudimentary theory of sociability. Only with hindsight remark about appetitus societatis been promoted to the starting point that flourished in writings later natural jurists. In this article, I address issue appearance Grotius's law sociability [as 1715/38 English translation John Morrice renders societatis, following Barbeyrac's sociabilité]. Writing just war tradition, Grotius is first all interested finding out conditions for peace, and although injustice condition...
DNA barcoding of a group European liverwort species from the genus Herbertus was undertaken using three plastid (matK, rbcL and trnH-psbA) one nuclear (ITS) marker. The barcode data were effective in discriminating among sampled contributed towards detection previously overlooked species, described here as H. norenus sp. nov. This shows clear-cut differences sequence for multiple regions is also morphologically distinct. useful clarifying taxonomic relationships with some Asia North America....
Abstract The results of nature restoration efforts have been characterized as notoriously unpredictable. Many variables impact the trajectory species communities towards recovery, and ecological theory that takes traits, habitat configuration scale into account, can improve models. However, most important questions regarding predictability community may be related to stochasticity. We investigated assembly a cyanolichen in chronosequence consisting 88 new forest patches (30–140+ years old)...
Observations of two apparent phenotypic expressions (morphodemes) the composite thallus lichen‐forming ascomycete species Ricasolia amplissima (Scop.) De Not. (formerly Lobaria Forss.) inspired us to investigate morphological and genetic variation in Norway. The morphodemes differ shape occurrence apothecia and/or cephalodia, each dominating climatically different parts southern We investigated morphology herbarium collections as well fresh samples from various areas, including localities...
Colonization studies may function as natural experiments and have the potential of addressing important questions about community assembly. We studied colonization for a guild epiphytic lichens in former treeless heathland area 170 km2 southwest Norway. investigated if lichen species richness composition on aspen (Populus tremula) trees corresponded to random draw individuals from regional pool. compared communities isolated young (55-120 yr) old (140-200 forest patches those an adjacent...
The role of dispersal in controlling the distribution species at landscape scale (10 2 –10 4 m) is still a matter dispute. Here, we use early colonization pattern 23 epiphytic lichen former tree‐less heathland (170 km ) to test three hypotheses on how colonized: A) mainly by long‐distance (LDD), B) rare LDD events followed limited local dispersal, and C) resulting front. study system consisted chronosequence 94 habitat patches constituting 0.4% area, with minimum inter‐site distance 0.2 km....
Abstract: To evaluate the efficiency by which fine‐scale diversity hotspots capture threatened species in northern forests, we investigated spatial distribution of vascular plants, bryophytes, macrolichens, and polypore fungi with 1‐ha resolution (in 0.25‐ha plots) within six approximately 2‐km 2 forest landscapes Norway. Of 1295 recorded (118,000 records), 62 (842 records) were on Norwegian Red List, 7 (12 new to We studied degree clustering different red‐listed among plots comparing...
Abstract Questions How are the fine‐scale spatial distribution and abundance of epiphytic lichens explained by factors related to environmental filtering local dispersal? Are same underlying across sites for: (1) each species separately; or (2) groups with similar dispersal strategies? Location Ten lowland deciduous forests at southwest coast N orway (60ºN, 5ºE). Methods We investigated abundance, given occurrence, 15 L obarion in ten forest sites: six 1800‐m 2 study four 5000‐m sites....
We investigated the relationship between site productivity and diversity of vascular plants, bryophytes, lichens, polypore fungi in forests based on species richness data 0.25 ha forest plots (grain size), selected from six 150–200 study areas (focus), spanning over a latitudinal distance 1350 km (extent) Norway. 1) searched for prevailing productivity‐diversity relationships (PDRs), 2) compared PDRs among taxonomic groups found different micro‐habitats, 3) effect increasing plot (grain)...
