Comparative Analyses of Plastid Sequences between Native and Introduced Populations of Aquatic Weeds Elodea canadensis and E. nuttallii
Non-indigenous species (NIS) are species living outside their historic or native range. Invasive NIS often cause severe environmental impacts, and may have large economical and social consequences. Elodea (Hydrocharitaceae) is a New World genus with at least five submerged aquatic angiosperm species living in fresh water environments. Our aim was to survey the geographical distribution of cpDNA...
متن کاملDo environmental factors influence composition of potential allelochemicals in the submersed freshwater macrophyte Elodea nuttallii (Hydrocharitaceae)?
Since Elodea nuttallii (Planch.) St. John was introduced to Europe from North America in 1939 it has invaded many water bodies and is widely spread over the continent. Its success is usually related to ease of adaptation to several environmental factors (DENDÈNE et al. 1993, JONES et al. 1993, OZIMEK et al. 1993, SIMPSON 1990). Our research, however, indicates that chemical defenses may play an...
متن کاملDistribution and morphological variations of invasive macrophytes Elodea nuttallii (Planch.) H. St. John and Elodea canadensis Michx in Croatia
The invasive species Elodea nuttallii was recorded for the fi rst time in the Croatian fl ora in 2006, in the drainage channels of Kopački rit (Baranja). After its establishment, E. nuttallii begins to spread to the eastern and northern part of the drainage channel network from 2006–2009. High water levels are responsible for the linear spreading direction of E. nuttallii, E. nuttallii and E. c...
متن کاملChemoecological investigations of the invasive waterweeds Elodea spp
The highly invasive waterweed Elodea nuttallii is still spreading vigorously in many European waterbodies and progressively displacing the formerly introduced E. canadensis. The full extent of this displacement seems underestimated because E. nuttallii exhibits a high phenotypic plasticity and may resemble E. canadensis in the vegetative state, thus impeding a clear taxonomic identification. We...
متن کاملAllelopathic activity of Elodea canadensis and Elodea nuttallii against epiphytes and phytoplankton
Elodea nuttallii and Elodea canadensis have both been introduced from North America to Europe. They are now common in many water bodies where they often form dominating stands. It was suggested that negative relationships between Elodea and phytoplankton or epiphytic covers exist, probably due to the release of growth inhibiting allelochemicals. This would be an effective strategy to avoid ligh...
