Traditionally, all authors in Latvia summarise all agamic species of the Ranunculus auricomus complex under three species: R. auricomus L., R. fallax (Wimm. et Grab) Sloboda, and R. cassubicus L. However, there are many compelling studies showing that the R. auricomus complex is a large assembly of apomictic microspecies. In this article, 17 specie...

Rosa rubiginosa L. is a rare and protected species and was included in the last Red Data book of Latvia as endangered species (EN) and recognized as data deficient (DD) species in neighboring Baltic States. The occurrence of the species in Latvia is decreasing. The species could be threatened by shifting agriculture, transforming grassland areas in...

Carex stenophylla Wahlenb. (Cyperaceae) is recorded as a new species for Latvia and the Baltic States flora on the basis of herbarium material first collected by P. Evarts-Bunders, in Daugavpils (Latvia). In Latvia the species has been identified in their typical habitat - xeric sandy grassland. Current locality identified far northward of the main...

Invasive plant species are one of the greatest threats against the biological diversity. The successful invasion by alien species is almost irreversible, because most invasive alien species have succeeded in spreading in large numbers before they have been observed. And it becomes almost impossible and very expensive to eliminate them. (www.nobanis...

Invasive alien plant species are a main threat to global biodiversity, natural flora and protected biotopes. In Latvia actual list of alien plant species consists 637 taxa or 33,5 percent of whole flora of Latvia with very different level of invasiveness – casual alien plants, arboreal trees with episodic escaping from cultivation, local invasions...

With the increase of requrements towards the quality of the environment, there is a growing need for well-planned and aesthetic green areas (Jankevica 2013). In the urban environment greenery plays an essential role as a component of “nature foundation”, which establishes a link between the natural and anthropogenic environment as well as carries o...

Invasive alien plant species cause important ecological and economic looses in Latvia, as they do worldwide. Effective management of alien plant species requires their appropriate grouping and prioritisation in national scale. Current official list of invasive organisms in Latvia includes only Heracleum sosnowskii Manden. (Cabinet regulation No. 46...

Corispermum is known as one of taxonomically most problematic genus in Chenopodiaceae and species identification is primarily based on fruit characters and presence or absence of perigonium. Six species were reported for the territory of Baltic countries and Latvia. The endemic species for Eastern Baltic region – C. intermedium Schweigg. is conside...

The study was performed on the basis of an inventory of the genus Tilia in Latvia. A total of 134 dendrological objects were inventoried in order to clarify factors limiting the distribution of linden in the territory of Latvia.

Invasive plant species are one of the greatest threats against the biological diversity. Prevention is indeed easier and much cheaper than cure. The successful invasion by alien species is almost irreversible, because most invasive alien species have succeeded in spreading in large numbers before they have been observed.

Одним из наиболее точных показателей влажности вегетационного периода конкретных территорий является гидротермический коэффициент (ГТК), который равен отношению количества осадков, выраженных в мм за период с температурами воздуха выше 10° к сумме активных температур за тот же период. Долгосрочный (более 30 лет) ГТК на территории Латвии – величины...

The flora of Daugavpils City is among the most peculiar and unique in Latvia. Its richness is defined by large habitat diversity, well-pronounced climate continentality, and the city has a long history as a centre of transportation networks and industries. In the city (72.48 km2) 1079 vascular plant species including 281 non-native plant species (a...

Level of winter hardiness of arboreal plants directly depends on different climatic factors, most important of them – extremely low winter temperatures, long-term average temperature of January – coldest winter month in Latvia, as well as daily amplitudes of temperatures during winter season. Winter of season 2009./2010. is considered as one of the...

In this paper, the species of genus Tilia found in Latvia were reviewed: 17 species, 6 subspecies and 6 interspecific hybrids. For each taxon the scientific nomenclature was adjusted, and morphology and distribution was described. Distribution maps for the commonest species in Latvia and a key for the Tilia species found Latvia were compiled.

The issue of invasive species in Latvia is very important. The research on invasive species in Daugavpils,the second largest city of Latvia, started at the end of the 19th century and first records from other partsof the country are from the end of the 17th century. In total, 206 invasive species are reported from Lat-via. Alien taxa of trees occur...
