Relative impact of pollen and seed dispersal on population viability of a neotropical tree species
Cerrado is one of the largest biomes in Brazil and has undergone constant changes in its landscape over the years. Modifications driven by the...
-
Pollen dispersal distance is determined by phenology and ancillary traits but not floral gender in an andromonoecious, fly-pollinated alpine herb
Pollen-mediated gene flow and spatial genetic structure have rarely been studied in alpine plants that are pollinated by dipteran insects. In...

Contribution of external dispersal to pollen pool genetic diversity in a riparian population of Cercidiphyllum japonicum
This study aimed to elucidate the contribution of pollen immigration to the maintenance of genetic diversity in the pollen pools received by seed...
-
Pollen dispersal patterns and male reproductive success based on pedigree reconstruction in a hybrid larch (Larix gmelinii var. japonica × L. kaempferi) open-pollinated seed orchard
Pollen dispersal patterns and male reproductive success are crucial factors for seed orchard management. Information on pedigree reconstruction is...

Body-size dependent foraging strategies in the Christmas Island flying-fox: implications for seed and pollen dispersal within a threatened island ecosystem
BackgroundAnimals are important vectors for the dispersal of a wide variety of plant species, and thus play a key role in maintaining the health and...

Pollen dispersal and mating patterns determine resilience for a large-yet-fragmented population of Cariniana estrellensis
Forest fragmentation studies are now urgent due to increased rates of deforestation and forest fires worldwide. In South America, the bee-pollinated Ca...

Seed Dispersal in Pines (Pinus)
Pines (n = 121 species) are important elements of forest ecosystems. They are economically and ecologically valuable and are often at the center of...

Seed Dispersal Ecology in Neotropical Melastomataceae
Melastomataceae species successfully colonize, and in many cases dominate, ecosystems ranging from forest to open vegetation, from sea level to...

Heterochrony and repurposing in the evolution of gymnosperm seed dispersal units
BackgroundPlant dispersal units, or diaspores, allow the colonization of new environments expanding geographic range and promoting gene flow. Two...

Distance-dependent mating but considerable pollen immigration in an isolated Quercus rubra planting in Germany
Gene flow affects the genetic diversity and structure of tree species and can be influenced by stress related to changing climatic conditions. The...

Seed and pollen dispersal and fine-scale spatial genetic structure of a threatened tree species: Pericopsis elata (HARMS) Meeuwen (Fabaceae)
Seed and pollen dispersal are important for defining sustainable forest management practices. By reducing population density, selective logging could...
-
Hybrid Seed Production Technology
Hybrid technology, harnessing the advantage of heterosis between two diverse genotypes to achieve maximum hybrid vigour, is widely recognized and...
-
Biotic interactions prior to seed dispersal determine recruitment probability of peyote (Lophophora diffusa, Cactaceae), a threatened species pollinator-dependent
Seedlings recruitment is key to maintaining populations and depends on diverse biotic interactions and abiotic factors before and after seed...
-
Frugivory and Seed Dispersal
Consumption of fleshy fruits by frugivorous animals, which then disperse the seeds inside, is a key ecological process, particularly in forests....
-
The comparison of dispersal rate between invasive and native species varied by plant life form and functional traits
A long dispersal distance is widely used to indicate high invasiveness, but it ignores the temporal dimensions of plant invasion. Faster dispersal...

Seed Development and Maturation
In plants, a fascinating set of post-fertilization events result in the development of a dispersal unit known as a seed. During the maturation phase,...

Embryological observations on seed abortion in Hibiscus syriacus L. and physiological studies on nutrients, enzyme activity and endogenous hormones
Under natural conditions, most Hibiscus syriacus L. individuals form very few mature seeds or the mature seeds that do form are of poor quality. As a...

Long distance pollen dispersal and intrapopulation genetic structure determined by clonal diversity in Hymenaea stigonocarpa populations of the Brazilian savanna
Key messageAlthough all populations show extensive pollen immigration, the occurrence of spatial genetic structure and biparental inbreeding...

Pollen Grain Morphology and Viability and Arthropod Visitation
Mora de Castilla pollen grains are tricolporate bearing three pores and three colpi. Pollen size is 27.51 μm in diameter, and pollen tube is 55 μm in...

Cenozoic seeds of Vitaceae reveal a deep history of extinction and dispersal in the Neotropics
The remarkably diverse plant communities of the Neotropics are the result of diversification driven by multiple biotic (for example, speciation,...
