Low levels of realized seed and pollen gene flow and strong spatial genetic structure in a small, isolated and fragmented population of the tropical tree Copaifera langsdorffii Desf
(Nature Publishing Group, 2011-01-01)
Over the past century, the Brazilian Atlantic forest has been reduced to small, isolated fragments of forest. Reproductive isolation theories predict a loss of genetic diversity and increases in inbreeding and spatial ...

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 ...
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 case study of anisotropic airborne pollen transport in Northern Patagonia using a Lagrangian particle dispersion model
(Elsevier Science, 2018-11)
Accumulated pollen sequences are used to infer temporal changes in vegetation composition. Pollen transport and dispersal by winds introduce large biases in the interpretation of pollen records. In order to calibrate the ...
Effects of selective logging on the mating system and pollen dispersal of Hymenaea courbaril L. (Leguminosae) in the Eastern Brazilian Amazon as revealed by microsatellite analysis
(Elsevier B.V., 2011-11-01)
Using nine microsatellite loci, we studied the effects of selective logging on genetic diversity, mating system and pollen dispersal in a population of the tree species Hymenaea courbaril, located in a 546 ha plot in the ...

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 ...
Understanding the effects of isolation on seed and pollen flow, spatial genetic structure and effective population size of the dioecious tropical tree species Myracrodruon urundeuva
(Springer, 2010-10-01)
This study examines the levels of gene flow, the distance and the patterns of pollen and seed dispersal, the intra-population spatial genetic structure (SGS) and the effective population size of a spatially isolated ...
