Sexual regeneration on a tropical inselberg in French Guiana: an inselberg specialist versus a species with a wider ecological amplitude

Popis výsledku v původním jazyce

I studied whether the two congeners, which differ in ecological amplitudes, also differ in effectiveness of sexual regeneration and survival strategies. The two Clusia species studied differed in parameters of individual recruitment stages such as preservation of seed germinability, seedling mortality and juvenile distribution. C. blattophila, the inselberg specialist, suffered high losses during the whole recruitment process and had low juvenile density. Survival is effected by individual persistence and supported by extensive vegetative growth. C. nemorosa has inefficient primary dispersal and high seedling mortality, but exhibits higher germination rate, higher preservation of seed germinability and numerous juveniles in the community. This suggeststhat sexual reproduction is important for C. nemorosa, but the ability to reproduce is limited due to the ecosystem characteristics. From the long-term perspective, both species have a limited ability to colonize open microhabitats.
