The name Huea, used for a lichen genus which hosts the two common Antarctic species H. cerussata and H. grisea (= H. coralligera), was formally recommended for rejection by the Nomenclature Committee for Fungi. Based on molecular data, we transfer these two species to the genus Hueidea. Hueidea was originally described in the family Fuscideaceae fo...
Assessment methods have been developed to estimate a preliminary conservation status for species and subsequently to facilitate the building of Red Lists. Such pre-assessment methods could be particularly useful in the French Overseas Territories (FOTs) where Red Lists tend to be out-dated or absent and where a high number of endemic species face d...

Litter decomposition is a key process for carbon and nutrient cycling in terrestrial ecosystems and is mainly controlled by environmental conditions, substrate quantity, and quality as well as microbial community abundance and composition. In particular, the effects of climate and atmospheric nitrogen (N) deposition on litter decomposition and its...
A broad range of climatic and biogeographical conditions are represented in the French Overseas Territories, from sub-polar to equatorial, resulting in a high diversity of endemic species. We mobilized data from herbaria, floras, checklists, literature, the expertise of botanists and plant ecologists to compile the most complete dataset on endemic...
Background and aims – Despite the ongoing taxonomical revision of the entire (sub)-Antarctic diatom flora, our knowledge on the ecology and community associations of moss-inhabiting diatoms is still rather limited. In the present study, our research aim was to survey the diversity together with the environmental factors structuring the epiphytic mo...
The genus Thelopsis was classified in the family Stictidaceae but its systematic position has never been investigated by molecular methods. In order to determine its family placement and to test its monophyly, fungal DNA of recent collections of Thelopsis specimens was sequenced. Phylogenetic analyses using nuLSU, RPB 2 and mtSSU sequences reveal t...
The flightless beetle Merizodus soledadinus, native to the Falkland Islands and southern South America, was introduced to the sub-Antarctic Kerguelen Islands in the early Twentieth Century. Using available literature data, in addition to collecting more than 2000 new survey (presence/absence) records of M. soledadinus over the 1991–2018 period, we...
The flightless beetle Merizodus soledadinus, originating from the Falkland Islands, was introduced to the sub-Antarctic Kerguelen Islands. We compiled the existing information on ship visits and landings on these islands to confirm the introduction date of M. soledadinus. Using data available in the literature, in addition to collecting more than 2...
An unknown Pinnularia taxon was recorded during a survey of the limno-terrestrial diatom flora of some hot springs in the Val Travers area (Grande Terre, Iles Kerguelen, sub-Antarctic region). The morphology of the species was investigated using both light and scanning electron microscopy. Based on these results, the species could not be identified...
Many social-ecological system(SES)-based approaches have been proposed to address environmental problems. Most social-ecological frameworks developed to date, however, lack clear operational linkages between humans and nature to efficiently guide SESs toward resilience. A conceptual framework designed to be operational is therefore necessary, as we...

During a survey of the non-marine diatom flora of the volcanic islands, Ile Amsterdam and Ile Saint-Paul (southern Indian Ocean), seven species belonging to the terrestrial diatom genus Humidophila have been recorded. Apart from five previously known taxa (Humidophila contenta, H. crozetikerguelensis, H. gallica, H. brekkaensis, H. vidalii), two ta...
Five species of the terrestrial diatom genus Luticola D.G.Mann were found during a taxonomic survey of two small volcanic islands, Ile Amsterdam and Ile Saint-Paul (Southern Indian Ocean). Apart from the two already known Luticola species L. beyensii Van de Vijver et al. and L. subcrozetensis Van de Vijver et al., two new species are described: L....
A new centric diatom genus, Ferocia Van de Vijver & Houk gen. nov. is described based on Melosira setosa Greville. Several samples collected in lava tunnels on Ile Amsterdam, a small isolated, volcanic island in the southern Indian Ocean where the latter taxon dominated the diatom flora, were investigated. The new genus is characterized by having h...
Our knowledge of the main determinants of invasion success is still incomplete. Among these factors, the effects of biological traits, including fecundity, longevity and dispersal in newly colonised regions, are pivotal. However, while numerous studies have considered ecological and evolutionary impacts of non-native species, their biology often re...

Syntrichia norvegica was found in the northern Velebit Mountains, in an area with the most outstanding and extreme karst relief, with steep slopes, perpendicular rocks, screes and deep dolines. The locality is situated in the Pinus mugo Turra belt, but owing to its position in the shaded bottom of a deep, funnel-shaped doline with slopes inclined a...
In the present work, we conducted a field-based study to identify the type of habitats colonized by the alien ground beetle Merizodus soledadinus at the Kerguelen Islands, southern Indian Ocean, and to delineate the spatial dynamics of this species. We used periodic trapping at several coastal habitats on Ile Haute (one of the islands from the Kerg...
The liverworts of Île Amsterdam are surveyed. On the basis of historical collections and specimens collected on the island in 2006 and 2007 some 29 species and one variety belonging to 18 families have been recorded. This means that in comparison with the last survey of the island's hepatics, in 2002, the number of taxa has been nearly doubled. Of...
Invasive alien species (IAS) are one of the most serious threats to the rich and unique biodiversity of the 13 French overseas territories (FOTs) scattered across three oceans and two continents. To address this critical issue, a dedicated Initiative has been conducted since 2005, with the support of a large panel of
national and local experts and...

Thouvenot 3086 (BCB 58238). According to Casas (2005) this species was pre-viously unrecorded in Andorra (Eastern Pyrenees) although it is known in the neighbouring...
Despite considerable research on biological invasions, key areas remain poorly explored, especially ways to reduce unintentional propagule transfer. The Antarctic represents a microcosm of the situation, with the numbers of established non-native species growing. Information to help reduce potential impacts is therefore critical. We measured the pr...
Diatom and water chemistry samples were collected during the austral summer of 2007 from lakes, streams and bogponds on Ile Amsterdam (TAAF), a small island located in the southern Indian Ocean. A diverse diatom flora of 104 taxa was found, dominated by several Pinnularia taxa, Frustulia lebouvieri, Kobayasiella subantarctica, Eunotia paludosa, E....
Syntrichia christophei Ochyra et R.H. Zander is new to science from Îles Kerguelen in the Subantarctic. The species is described and illustrated and its affinities are discussed. It is closely related to S. saxicola (Cardot) R.H. Zander but it is easily distinguished by its larger leaf size, larger distal laminal cells, longer awn at the leaf apex,...
Ecophenotypes reflect local matches between organisms and their environment, and show plasticity across generations in response to current living conditions. Plastic responses in shell morphology and shell growth have been widely studied in gastropods and are often related to environmental calcium availability, which influences shell biomineralisat...

Bakalin Russian Federation (the Russian Far East): Magadan Province, Magadan City vicinity, Gertnera Bay, area near Staraya Vesyolaya neighbourhood, 59u30927.30N, 150u56911.10E, 15 m a.s.l., wet, fine-grained soil in the crevices in open site, mixed with Pre...
As a biological invasion proceeds, the spread of the alien may promote dispersal ability at the front by direct and indirect selection, thereby altering the dynamics of the invasion. Morphology correlates with dispersal in numerous taxa, and represents a relevant integration of temporal or geographical changes in dispersal. Using data from Laparie...
Environmental manipulation studies are integral to determining biological consequences of climate warming. Open Top Chambers (OTCs) have been widely used to assess summer warming effects on terrestrial biota, with their effects during other seasons normally being given less attention even though chambers are often deployed year-round. In addition,...
