Spatial and temporal variation of community composition and species cover following dune restoration in the Devesa de Albufera (Valencia, Spain).
2015
Plant populations were reintroduced to the coastal dune bar of the Devesa de Albufera from 1988 to 2004; different coastline sections received different species composition and cover. With the aim to detect spatial and temporal variation of floristic diversity, we compared current species composition and cover across the length of the Devesa and across the dune bar with those imposed at the time of restoration. Non-metric multidimensional scaling (NMDS) detected significant differences both across the dune faces and across the coast sections. Differences across the dune faces reflect the sea-inland ecological gradient and resulted from a spatial rearrangement of plant populations: Calystegi…
Long-distance seed dispersal, clone longevity and lack of phylogeographical structure in the European distributional range of the coastal Calystegia …

Aim To explore the relative effects of Quaternary climatic history vs. species-specific biological properties (high seed dispersability, high seed longevity, clonal growth) on phylogeographical structure in European Mediterranean and Atlantic Ocean and Black Sea material of the coastal dune plant Calystegia soldanella (L.) R. Br. Location Black Sea and European Mediterranean and Atlantic Ocean coasts. Methods Variation in amplified fragment length polymorphism was analysed at two different sampling levels. First, an entire-range sample from the Black Sea to the North Sea, including single individuals from sites evenly spread along this entire coast was analysed. Second, in a population-l…
Jūras piekrastē sastopamo vīteņaugu Calystegia sepium un Calystegia soldanella sālsizturība: modeļsistēmas izveide un aprobācija
2021
Pētījuma mērķis bija kontrolētos apstākļos pārbaudīt žoga dižtīteņa un Calystegia soldanella sālsizturību un jonu uzkrāšanos NaCl ietekmē, izmantojot veģetatīvās pavairošanas modeļsistēmu, kas izveidota no dažādos biotopos pieejamiem žoga dižtīteņa augiem un Calystegia soldanella komerciāli pieejamām sēklām. Augus audzēja automātiskajā siltumnīcā, apstrādāja ar dažādu koncentrāciju NaCl. Pēc novākšanas veica mērījumus un jonu analīzes žāvētām augu daļām. Žoga dižtīteni var efektīvi pavairot ar nobriedušu rizomu fragmentiem un dzinumu spraudeņiem ar lapu. Pēdējā gadījumā pavairoto augu augšanas potenciāls laikā ir ierobežots. C. soldanella var efektīvi pavairot ar dzinuma spraudeņiem ar lapu…
