Uncoupling the effects of seed predation and seed dispersal by granivorous ants on plant population dynamics. [PDF]

PLoS ONE, 2012
Secondary seed dispersal is an important plant-animal interaction, which is central to understanding plant population and community dynamics. Very little information is still available on the effects of dispersal on plant demography and, particularly ...

Arbuscular Mycorrhizal Fungi Taxa Show Variable Patterns of Micro-Scale Dispersal in Prairie Restorations

Frontiers in Microbiology, 2022
Human land use disturbance is a major contributor to the loss of natural plant communities, and this is particularly true in areas used for agriculture, such as the Midwestern tallgrass prairies of the United States.

Is There an Equivalence between Measures of Landscape Structural and Functional Connectivity for Plants in Conservation Assessments of the Cerrado?

Land, 2020
Landscape connectivity can be assessed based on the physical connection (structural connectivity) or the maintenance of flow among habitats depending on the species (functional connectivity).

Seed Size, Seed Dispersal Traits, and Plant Dispersion Patterns for Native and Introduced Grassland Plants

Plants, 2023
Most terrestrial plants disperse by seeds, yet the relationship between seed mass, seed dispersal traits, and plant dispersion is poorly understood. We quantified seed traits for 48 species of native and introduced plants from the grasslands of western Montana, USA, to investigate the relationships between seed traits and plant dispersion patterns ...

Quantifying patch‐specific seed dispersal and local population dynamics to estimate population spread of an endangered plant species

Ecology and Evolution, 2021
Aim Habitat loss and fragmentation impose high extinction risk upon endangered plant species globally. For many endangered plant species, as the remnant habitats become smaller and more fragmented, it is vital to estimate the population spread rate of ...

Human-mediated dispersal of seeds by the airflow of vehicles. [PDF]

PLoS ONE, 2013
Human-mediated dispersal is known as an important driver of long-distance dispersal for plants but underlying mechanisms have rarely been assessed. Road corridors function as routes of secondary dispersal for many plant species but the extent to which ...

Seed dispersal by wind decreases when plants are water‐stressed, potentially counteracting species coexistence and niche evolution

Ecology and Evolution, 2021
Hydrology is a major environmental factor determining plant fitness, and hydrological niche segregation (HNS) has been widely used to explain species coexistence.

Measuring Splash Dispersal of a Major Wheat Pathogen in the Field

PhytoFrontiers, 2022
Capacity for dispersal is a fundamental fitness component of plant pathogens. Characterization of plant pathogen dispersal is important for understanding how pathogen populations change in time and space.

Intraspecific Variation of Samara Dispersal Traits in the Endangered Tropical Tree Hopea hainanensis (Dipterocarpaceae)

Frontiers in Plant Science, 2020
Propagule dispersal is a crucial life history stage, which affects population recruitment and regeneration as well as community structure and functions.

Warming increases the spread of an invasive thistle. [PDF]

PLoS ONE, 2011
BACKGROUND: Global warming and shifted precipitation regimes increasingly affect species abundances and distributions worldwide. Despite a large literature on species' physiological, phenological, growth, and reproductive responses to such climate change,
