Occurrence of Lindernia dubia in the Ipoly valley (Hungary and Slovakia)

Abstract

Abstract:A survey for invasive alien species was carried out along the Ipoly River (Danube catchment area) at the border between Hungary and Slovakia in 2010 and 2011. Lindernia dubia was found in three locations on both sides of the river. Th e paper gives the fi rst record of the species in the Ipoly (Ipel') Catchment Area (Hungary and Slovakia), previously, the species has not been reported from the Matricum fl ora district of Hungary. Th is paper describes the newly discovered localities (status of phenology, accompanied species, ecological and hydrological conditions, etc.). It also explains the spread and possible regional origin of the species. Th e recent CEU-based distribution map is also presented.

Genus Lindernia All. (Linderniaceae) in Bosnia and Herzegovina

“…In Europe, L. dubia was first recorded in the 19th century in France (Llyod 1868). At present the occurrence of this species has been recorded in Albania (Barina et al 2015), Austria (Raabe 2019(Raabe , 2021, Belgium (Vannerom 1994), Bulgaria (Markova 1995), Croatia (Csiky & Purger 2008), Czech Republic (Kurka 1990;Šumberová et al 2012), Germany (Jage 1964), Greece (Dimopoulos et al 2013), Hungary (Molnár et al 2000;Schmotzer 2015), Italy (Pignatti 1982;Galasso et al 2018), Netherlands (Simons & Jansen 2018), North Macedonia (Matevski 2017), Poland (Drobnik & Buchalik 2004), Portugal (Vasconcelos et al 1999), Romania (Ciocârlan & Costea 1994), Serbia (Ranđelović et al 2006;Perić & Knežević 2019), Slovakia (Schmotzer 2015;Hrivnák et al 2016;Dítě & Dítě 2019), Slovenia (Seliškar et al 1995;Trpin et al 1995), Spain (Sanz-Elorza et al 2001), Switzerland (Lauber et al 2012) and Turkey (Özhatay & Kültür 2006). In its native as well as secondary distribution range, L. dubia occurs in a variety of wet habitats, such as periodically flooded habitats, muddy or sandy banks of rivers, lakes, ponds and rice-fields (Šumberová et al 2012;Hrivnák et al 2016;Perić & Knežević 2019).…”

Alien (invasive) vascular plants in Slovakia – a story of successful plant immigrants

“…A North American species Lindernia dubia was recorded in southern Slovakia in the Ipeľ river valley in 2010 (SCHMOTZER, 2015) and later in 2015 in Central Slovakia in an artificial water reservoir (KOCHJAROVÁ ET AL., 2015). The species was introduced to these localities probably by ornitochory via aquatic birds or by anthropochory (HRIVNÁK ET AL., 2016).…”

New floristic records from Central Europe 6 (reports 81-98)

“…2019, R. Hrivnák, SAV. This alien species, native to North America, was found in the territory of Slovakia recently(Hrivnák et al 2016) and it is known from 3 localities: near Trenč, Štiavnické Bane and Štúrovo(Schmotzer 2015;Kochjarová et al 2015;Dítě & Dítě 2019). Similarly to the previous findings, the vegetation on the newly found locality near Lučenec town was classified into vegetation of exposed bottom ofIsoëto- Nanojuncetea Br.-Bl.…”
