CHROMOSOME COUNTS OF SOME ANGIOSPERM SPECIES FROM IRAN (III)
Original meiotic or mitotic chromosome counts are presented for 17 species in 12 families of angiosperms from Iran. Chromosome counts for Amberboa nana, n=16 (Asteraceae) and Camelina rumelica subsp. transcapica, n=13 (Brassicaceae) are repoted for the first time. Chromosome numbers for six species including: Rhagadiolus stellatus (n=5), Campanula raponcoloides (n=34), Campanula trachelium (n=1...
متن کاملPost-dispersal seed fates of four prairie species.
After dispersal, seeds can germinate and establish as seedlings, persist as seeds, or die. Knowledge of these three seed fates is crucial for understanding the abundance and distribution of plant populations and ultimately, community composition and diversity. Few studies, however, have simultaneously measured these fates, while also examining the factors causing mortality. The goal of this res...
متن کاملEndozoochorous seed dispersal of plant species in semi-steppe rangelands
During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...

متن کاملEvolutionary and ecological causes of species richness patterns in North American angiosperm trees
netic relatedness in species assemblages (see below). Here, we utilize a similar approach in North American angiosperm trees and fi nd that strong relationships between climate and richness are not an alternative explanation for richness but that these climate – richness relationships must themselves be explained by the ecological, evolutionary, and biogeographic processes of speciation, extinc...
