Weed seed predation in organic and conventional cereal fields [PDF]

open access: yesJulius-Kühn-Archiv, 2012
Granivores can consume a large proportion of newly produced weed seeds in crop fields each year. If substantial, granivores can help to exhaust the seed bank and thus contribute to long-term weed control.

High trees increase sunflower seed predation by birds in an agricultural landscape of Israel

open access: yesFrontiers in Ecology and Evolution, 2014
Natural habitats in agricultural landscapes promote agro-ecosystem services but little is known about negative effects (dis-services) derived by natural habitats such as crop seed predation.

Predation risk and personality influence seed predation and dispersal by a scatter‐hoarding small mammal

open access: yesEcosphere, 2023
Small mammals are key scatter hoarders in forest ecosystems, acting as both seed predators and dispersers. The outcome of their interactions (i.e., predation vs.

Spatial and temporal patterns of carabid activity-density in cereals do not explain levels of predation on weed seeds [PDF]

open access: yes, 2008
Seed predation is an important component of seed mortality of weeds in agro-ecosystems, but the agronomic use and management of this natural weed suppression is hampered by a lack of insight in the underlying ecological processes.

Pre-dispersal seed predation and abortion in species of Callisthene and Qualea (Vochysiaceae) in a Neotropical savanna

open access: yesActa Botânica Brasílica, 2014
The ability of plants to generate fertile offspring is influenced by morpho-physiological and ecological factors. Hence, reproductive success is directly linked to factors affecting quantity and quality of their progeny.

Weed seed predation by granivorous carabids as influenced by carnivorous carabids

open access: yesJulius-Kühn-Archiv, 2014
Weed seed predation is influenced for both biological and abiotic factors. Knowledge about these factors is necessary to optimize seed predation as a biological weed control measure.

Are the Interactions between Oaks and Pre-Dispersal Seed Predators Retained in Urban Environments? An Analysis of Two Quercus Species in Southern Mexico City

open access: yesDiversity, 2022
As urbanization proceeds, natural ecosystems surrounding cities are transformed, but usually some elements persist, notably trees from forest ecosystems.

Population dynamics of a long-lived alpine plant with sexual and clonal reproduction [PDF]

open access: yes, 2006
This thesis focuses on the demography, reproduction, and pre-dispersal seed predation of the alpine clonal plant Geum reptans. In chapter 2, I studied the population dynamics of G.

Effect of woodland patch size on rodent seed predation in a fragmented landscape [PDF]

open access: yesWeb Ecology, 2007
Predation on large woody plant seeds; chestnuts, acorns and sloe kernels, was studied in deciduous forests of two size classes: small woodlots (<1 ha) and large woods (at least 25 ha) in southern Sweden.

Weed seed choice by carabid beetles (Coleoptera: Carabidae): Linking field measurements with laboratory diet assessments

open access: yesEuropean Journal of Entomology, 2014
Carabid beetles could potentially provide a number of ecosystem services in arable fields, including the regulation of weeds by eating seeds. Spatio-temporal variability in the incidence of predation combined with a limited understanding of the ...
