description

Darba mērķis ir noteikt veģetācijas ietekmi uz cikāžu sabiedrībām un to struktūru Apšuciema kaļķainajā zāļu purvā. Pētījuma vieta atrodas Apšuciema zāļu purvā, Engures novadā. Cikāžu paraugi ievākti un veģetācija noteikta 57 parauglaukumos. Cikāžu sabiedrību struktūra ir heterogēna, veidojas sabiedrību izmaiņu, līdzības gradients. Visaugstākā cikāžu daudzveidība, sugu un indivīdu skaits sastopams ekotonā, un to būtiski pozitīvi ietekmē augu sugu skaits un daudzveidība. Subdominantās sugas fiziski sadala purva teritoriju. Retākās sugas izplatītas galvenokārt ekotonā. Konstatēta atsevišķu cikāžu sugu izplatības atkarība no barības auga izplatības. Visnegatīvāko ietekmi uz cikāžu sabiedrībām rada dižā aslape. Zilganā molnija un parastā niedre uz dižās aslapes fona cikāžu sabiedrības ietekmē pozitīvi.
