AoB Plants, 2019 There is growing realization that intraspecific variation in seed dispersal can have important ecological and evolutionary consequences. However, we do not have a good understanding of the drivers or causes of intraspecific variation in dispersal, how ...

Antagonistic and mutualistic interactions alter seed dispersal of understory plants at forest edges
Ecosphere, 2021 Seed dispersal by ants is an important interaction in North American eastern deciduous forests, where 30–40% of understory plants are myrmecochores, with seeds that possess lipid‐rich appendages (elaiosomes) that attract seed‐dispersing ants ...

From passive to informed: mechanical mechanisms of seed dispersal.
New Phytologist, 2019 Plant dispersal mechanisms rely on anatomical and morphological adaptations for the use of physical or biological dispersal vectors. Recently, studies of interactions between the dispersal unit and physical environment have uncovered fluid dynamic ...

Odor of achlorophyllous plants’ seeds drives seed‐dispersing ants [PDF]
Ecology and Evolution, 2021 AbstractSeed dispersal by ants is an important means of migration for plants. Many myrmecochorous plants have specialized appendages in their seeds called elaiosome, which provides nutritional rewards for ants, and enable effective seed dispersal. However, some nonmyrmecochorous seeds without elaiosomes are also dispersed by ant species, suggesting the

Employing plant functional groups to advance seed dispersal ecology and conservation
AoB Plants, 2019 Seed dispersal enables plants to reach hospitable germination sites and escape natural enemies. Understanding when and how much seed dispersal matters to plant fitness is critical for understanding plant population and community dynamics.

Hierarchical mechanisms of spatially contagious seed dispersal in complex seed‐disperser networks [PDF]
Ecology, 2014 Intra‐ and interspecific spatially contagious seed dispersal has far‐reaching implications for plant recruitment, distribution, and community assemblage. However, logistical and analytical limitations have curtailed our understanding concerning the mechanisms and resulting spatial patterns of contagious seed dispersal in most systems and, especially ...

Mesopredator frugivory has no effect on seed viability and emergence under experimental conditions
Ecosphere, 2021 Members of the order Carnivora are a unique and important seed disperser who consume and deposit undamaged seeds while providing regular long‐distance seed dispersal opportunities.

Animal movement drives variation in seed dispersal distance in a plant–animal network
Proceedings of the Royal Society B, 2019 Frugivores play differing roles in shaping dispersal patterns yet seed dispersal distance is rarely quantified across entire communities. We model seed dispersal distance using gut passage times and bird movement for the majority (39 interactions) of ...

Seed traits and burial state affect plant seed secondary dispersal mediated by rodents
HeliyonSeed dispersal is an important ecological process and has important implications for plant population expansion and regeneration. Seed dispersal not only reduces the probability of death due to seed density but also facilitates seedling establishment ...
