Pollen-mediated gene flow across fragmented clonal stands of hybrid eucalypts in an exotic environment
(2015-11-15)
We investigated the rate of pollen-mediated flow and realized reproductive success at increasing distances from the source, across fragmented clonal stands of hybrid eucalypts in Brazil by parentage analysis of grown out ...
Extensive pollen flow in a natural fragmented population of Patagonian cypress Austrocedrus chilensis
(Springer Heidelberg, 2014-07-30)
Habitat fragmentation might significantly affect mating and pollen dispersal patterns in plant populations, contributing to the decline of remnant populations. However, wind-pollinated species are able to disperse pollen ...
Mating system and pollen flow between remnant populations of the endangered tropical tree, Guaiacum sanctum (Zygophyllaceae)
(2011)
Tropical trees are generally long-lived making it difficult to assess the long-term effects of habitat fragmentation on genetic diversity. Maintenance of genetic diversity in fragmented landscapes is largely dependent on ...
Extensive pollen flow in a natural fragmented population of Patagonian cypress Austrocedrus chilensis
(Springer, 2014-12)
Habitat fragmentation might significantly affect mating and pollen dispersal patterns in plant populations, contributing to the decline of remnant populations. However, wind-pollinated species are able to disperse pollen ...
Realized pollen flow and wildling establishment from a genetically modified eucalypt field trial in Southeastern Brazil
(2017-02-01)
Confined field trials of genetically modified (GM) trees are the essential step toward the identification of the most productive cultivars and the assessment of the likely environmental impacts of the GM trees including ...
Pollen dispersal in a population of Passiflora caerulea: spatial components and ecological implications
(Springer, 2019-09)
Sexual reproduction in Angiosperms mostly depends on pollen transfer mediated by an agent. In plants pollinated by biotic agents, reproductive success and population structure are mainly determined by pollinator behavior. ...
Pollen Dispersal Between Isolated Trees in the Brazilian Savannah: A Case Study of the Neotropical Tree Hymenaea stigonocarpa
(Wiley-Blackwell, 2011-03-01)
This case study examines the pollen dispersal distance, pollen dispersal patterns and intra-family genetic structure for isolated trees in pastures of the bat-pollinated Neotropical tree species Hymenaea stigonocarpa using ...
A trade-off between the amount and distance of pollen dispersal triggered by the mixed foraging behaviour of Sephanoides sephaniodes (Trochilidae) on Lapageria rosea (Philesiaceae)
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2006-05)
Nectar thieves may increase or decrease pollinator-mediated pollen flow and thus may have positive or negative effects on plant reproductive success. In temperate rainforests of South America, the hummingbird Sephanoides ...
Contemporary pollen flow, mating patterns and effective population size inferred from paternity analysis in a small fragmented population of the Neotropical tree Copaifera langsdorffii Desf. (Leguminosae-Caesalpinioideae)
(Springer, 2012-06-01)
Pollen flow and dispersal patterns were investigated in a small, isolated forest fragment of the Neotropical insect pollinated tree Copaifera langsdorffii, using paternity analysis and eight microsatellite loci. We also ...
