Historical and current occurrence of halophytic-ruderal species Hordeum geniculatum was studied in Slovakia during 2003 - 2010. The species occurred only in the Podunajská nížina Lowland, where 16 ...sites were found in total including historical and recent locations. Recently, the number of sites decreased markedly and we confirmed only four localities. Due to the sharp decrease in the number of sites and proper habitats, Hordeumgeniculatum is re-evaluated as endangered (EN) plant of Slovak flora.
Včlanku smo obravnavali historično in trenutno razširjenost halofitsko-ruderalne vrste Hordeum geniculatum na Slovaškem med leti 2003-2010. Vrsta se pojavlja le v nižini Podunajská nížina, kjer smo našli 16 lokalitet, vključno historičnih in recentnih. V zadnjem času je število rastišč zelo upadlo in potrdili smo samo štiri lokalitete. Zaradi močnega zmanjšanja števila lokalitet in primernih rastišč, predlagamo da se vrsta Hordeumgeniculatum v flori Slovaške obravnava kot ogrožena (EN)
Historical and current occurrence of obligate halophyte Artemisia santonicum subsp. patens was studied in Slovakia during 2001-2012. The species has been occurred in the Podunajska nižina Lowland and ...the Vychodoslovenska nižina Lowland; 35 localities were found in total. The data from the Zahorska nižina Lowland is erroneous. Recently the number of localities decreased markedly and the species was confirmed only in 17 sites. Most of them (16) is situated in the Podunajska nižina Lowland and a single one has been confirmed in the Vychodoslovenska nižina Lowland. Based on our data, Artemisia santonicum subsp. patens belongs to the endangered (EN A2ac+4c) plants of the Slovak flora according to IUCN categories and criteria, because 50 % of locations were destroyed and survival prognosis is unfavorable for the most recent populations.
V članku smo obravnavali historično in trenutno razširjenost obligatne halofitske vrste Artemisia santonicum subsp. patens na Slovaškem med leti 2001 in 2012. Vrsta se pojavlja v nižinah Podunajska nižina in Vychodoslovenska nižina; skupno smo našli 35 rastišč. Podatki o pojavljanju v nižini Zahorska nižina so napačni. Število rastišč se je v zadnjem času občutno zmanjšalo in pojavljanje vrste smo potrdili samo na 17 lokalitetah. Večina (16) je iz Podunajska nižina in samo ena iz Vychodoslovenska nižina. Na podlagi naših podatkov takson Artemisia santonicum subsp. patens uvrščamo med ogrožene (EN A2ac+4c) vrste slovaške flore na podlagi IUCN kategorij in kriterijev, saj je bilo uničenih 50% rastišč in tudi napovedi za preživetje trenutnih populacij so neugodne.
Distribution, morphological types and coenotic affinity of Gagea bohemica in Slovakia was studied during 2008-2011. Revision of herbarium material showed presence of three taxa in the flora: 1) ...subsp. bohemica, 2) subsp. bohemica var. stenochlamydea and 3) subsp. saxatilis. Taxonomic status of var. stenochlamydea is uncertain and requires further research. In total, 42 localities of G. bohemica sensu lato were documented. Nominate subsp. bohemica (including var. stenochlamydea) predominated and it was recently confirmed at 21 localities. These current sites represent about 50% of all known sites, therefore we re-assessed the status of G. bohemica in the Slovak Red List and we proposed the IUCN category EN (endangered) for this taxon. Subsp. saxatilis was found as new to Slovakia. The taxon occurred only at single locality (Vinosady) and it was not confirmed recently. We assessed it as data deficient (DD).
Proučevali smo razširjenost, morfološke tipe in fitocenološko navezanost vrste Gagea bohemica na Slovaškem v obdobju 2008-2011. Z revizijo herbarijskega materiala smo dokazali prisotnost treh taksonov: 1) subsp. bohemica, 2) subsp. bohemica var. stenochlamydea in 3) subsp. saxatilis. Taksonomski status var. stenochlamydea je negotov in potrebne so dodatne raziskave. Skupno smo zabeležili 42 lokalitet vrste G. bohemica sensu lato. Podvrsta subsp. bohemica (ki vključuje tudi var. stenochlamydea) prevladuje in je bila potrjena na 21 lokalitetah. Ta rastišča predstavljajo približno polovico vseh znanih, zato smo ponovno ocenili status vrste G. bohemica v Rdečem seznamu Slovaške in za ta takson predlagamo IUCN kategorijo EN (prizadeta vrsta). Pojavljenje podvrste subsp. saxatilis je novo na Slovaškem. Našli smo jo samo na eni lokaliteti (Vinosady) in uspevanje v zadnjem času ni bilo potrejno. Ocenjujemo jo s kategorijo DD (premalo podatkov).
