| diversity of rhizobial bacteria isolated from nodules of the gypsophyte ononis tridentata l. growing in spanish soils. | the aim of this work is to describe the diversity and phylogeny of rhizobial bacteria associated to nodules of ononis tridentata l. in different geographical regions of spain. twenty-two bacterial isolates were characterized using several molecular techniques (16s amplified ribosomal deoxyribonucleic acid restriction analysis, fingerprinting, and sequencing) and phylogenies were inferred from their 16s and nodc gene sequences. phylogenetically, the isolates grouped with the genera rhizobium, mes ... | 2008 | 18060448 |
| effects of season and population size on pollination and reproductive output in a mediterranean shrub. | pollinator guilds may change throughout extended flowering periods, affecting plant reproductive output, especially in seasonal climates. we hypothesised a seasonal shift in pollinator guild and an autumn reduction in pollinator abundance, especially in small and sparse populations. we recorded pollinator identity, abundance and behaviour in relation to flower density from plant to population throughout the extended flowering of ononis tridentata. we evaluated female reproductive output by recor ... | 2017 | 28135028 |
