Scales of synchrony [ edit] Within-year synchrony [ edit]. The synchrony of a population of flowering plants can be described within a season by how... Across-year synchrony [ edit]. In plant species which flower every year, complete across-year synchrony has been... Community synchrony [ edit]. ... See more Flowering synchrony is the amount of overlap between flowering periods of plants in their mating season compared to what would be expected to occur randomly under given environmental conditions. A population which … See more Coevolution can shape the trajectory of evolution for flowering synchrony in plants. Nearly 90% of flowering plants rely on animals for … See more A degree of within-season synchrony is expected for populations and communities due to the Moran effect, which posits that the degree of differentiation in phenology between … See more Fragmented populations Asynchronously flowering species are at particular risk for extinction following habitat fragmentation. Habitat fragmentation can … See more Synchronous flowering has been observed in nature for centuries. Sources from the ninth and 10th centuries noted the interannual … See more Synchronous flowering can occur across a season (intrannual synchrony) or across multiple years (interannual synchrony) within a species, or across coflowering species in a community. Populations and communities can exhibit multiple types of synchrony … See more Divergent patterns of flowering synchrony can result in speciation, and asynchronous flowering can prevent hybridization. By occupying different niches in flowering time, sympatric speciation can occur. This is the case in bamboo species with multiplicative … See more

WebSep 19, 2007 · Key Results. Most flowering patterns of Juncus were best described as synchronous pulsed flowering, characterized as population-wide concerted flowering events separated by days with no or few open flowers. Flowering synchrony and variability differed from a random pattern in most cases. CV values in combination with a … WebMar 17, 2024 · Such variability has the potential to affect flowering synchrony among populations and hence the potential for gene flow. Methods To test whether an earlier start of the growing season affects the potential for gene flow among populations, we quantified the distributions of flowering times of two spring-flowering plants ( Trillium erectum and ... both run

WebThe flowering period in Schima wallichii varied from 33 to 42 days with mean synchrony of 0.54 to 0.68 between the populations. The stigma was receptive up to 2.5 days only and showed slightly protandrous type of dichogamy. WebMar 18, 2016 · The overall interpopulation synchrony ratio for flowering and fruiting phenology was 0.75 and 0.85, respectively (Table 3). Higher synchrony ratio indicates greater coincidence of the phase among individuals or sites. Table 3 . Synchrony indices for phenological events of S. senegal within Lake Baringo woodland ecosystem.
