Spatio-temporal variation in population traits of Hepatica nobilis, a patchily distributed woodland herb [PDF]

, 2002
In the NE Iberian Peninsula, the herb Hepatica nobilis commonly occurs in the understory of deciduous forests. I report data on spatio-temporal variation in performance of patchily distributed populations in a beech forest at Montseny Natural Park (NE ...

CRYPTIC CONSEQUENCES OF A DISPERSAL MUTUALISM: SEED BURIAL, ELAIOSOME REMOVAL, AND SEED-BANK DYNAMICS

Ecology, 2004
In moving seeds from one location to another, dispersers define the ecological context that a plant will experience throughout its lifetime. Because seed deposition sites may benefit one plant life cycle stage but not others, dispersal may give rise to a conflict between a plant's dispersal needs (e.g., predator escape) and its requirements for ...

Mutualistic interactions facilitate invasive species spread

Functional Ecology, Volume 39, Issue 1, Page 254-267, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Invasive species are major drivers of global ecosystem change. They often displace native species through competitive exclusion, creating novel species interactions. These interactions can lead to ecological cascades, where the presence of one invasive species enhances ...

Invasive shrubs amplify seasonal granivory, revealing optimal windows for seed survival following invasive shrub removal

Ecosphere, Volume 15, Issue 12, December 2024.
Abstract Invasive shrubs dramatically reduce the biodiversity of native plants, making invaded areas important targets of conservation and restoration. Adding seeds of native plant species, in addition to the removal of invasive plants, is a potentially promising means for restoration of native plant communities. However, because seed survival may vary

Precipitation Drives Frugivory in a Subtropical Generalist Herbivore, the Gopher Tortoise, and Alters Its Functional Role as a Seed Disperser

Ecology and Evolution, Volume 14, Issue 11, November 2024.
A generalist herbivore, the gopher tortoise, becomes more frugivorous intra‐annually, following seasonal precipitation. As it increasingly becomes frugivorous, it disperses seeds exhibiting very different dispersal syndromes. At high levels of frugivory, this species behaves as a classical frugivore with regard to the types of seeds it disperses.

Genetic component of flammability variation in a Mediterranean shrub [PDF]

, 2014
Recurrent fires impose a strong selection pressure in many ecosystems worldwide. In such ecosystems, plant flammability is of paramount importance because it enhances population persistence, particularly in non‐resprouting species.

Leaf Volatiles from Two Corydalis Species Lure A Keystone Seed-dispersing Ant and Enhance Seed Retrieval [PDF]

, 2018
It has been reported that a suit of plant traits can regulate the ant-seed interaction and subsequently affect the seed dispersal. However, the role of plant volatiles in attracting the ants for seed dispersal remains little examined.

Anthropogenic disturbance as a driver of microspatial and microhabitat segregation of cytotypes of Centaurea stoebe and cytotype interactions in secondary contact zones [PDF]

, 2017
Background and Aims In a mixed-ploidy population, strong frequency-dependent mating will lead to the elimination of the less common cytotype, unless prezygotic barriers enhance assortative mating.

Incorporating Redispersal Microsites into Myrmecochory in Eastern North American Forests [PDF]

, 2016
Studies addressing the benefits of “directed dispersal” in ant seed dispersal systems have highlighted the beneficial soil properties of the nests of ants that disperse their seeds.
