Is increased male flower production a strategy for avoidance of predispersal seed predation in andromonoecious plants? [PDF]
Ecology and Evolution, 2021 Floral gender in angiosperms often varies within and among populations. We conducted a field survey to test how predispersal seed predation affects sex allocation in an andromonoecious alpine herb Peucedanum multivittatum.

Plant density can increase invertebrate postdispersal seed predation in an experimental grassland community. [PDF]
Ecol Evol, 2016 Janzen–Connell effects are negative effects on the survival of a plant’s progeny at high conspecific densities or close to its conspecifics. Although the role of Janzen–Connell effects on the maintenance of plant diversity was frequently studied, only ...

Hierarchical levels of seed predation variation by introduced beetles on an endemic Mediterranean palm. [PDF]
PLoS ONE, 2014 Seed predators can limit plant recruitment and thus profoundly impinge the dynamics of plant populations, especially when diverse seed predators (e.g., native and introduced) attack particular plant populations.

Defaunation of large mammals leads to an increase in seed predation in the Atlantic forests
Global Ecology and Conservation, 2015 Defaunation can trigger cascading events in natural communities and may have strong consequences for plant recruitment in tropical forests. Several species of large seed predators, such as deer and peccaries, are facing dramatic population collapse in ...

Field margins enhance weed seed predation in adjacent fields in early spring
Frontiers in Agronomy, 2023 Seed depletion by granivorous organisms can regulate weeds in arable agriculture. Enhancing this regulation can be achieved by adopting farming practices that favour seed predators.

Seed size of co‐occurring forb species predicts rates of predispersal seed loss from insects
Ecosphere, 2022 Plants often face chronic seed loss from predispersal seed predation by insects. Although many studies have documented the rates of seed loss for single species in different communities, it is unclear how rates of predispersal seed predation vary among ...

Plant Protection Science, 2022 Invertebrate seed predation is a potential ecosystem service that substantially reduces weed seeds in crop fields, decreasing the seedling emergence and, thus, limiting the weed competition next season.

Demographic Processes Allow Echinochloa crus-galli to Compensate Seed Losses by Seed Predation
Agronomy, 2021 The effect of weed management that targets the seed stage on subsequent life stages is largely unknown. Post-dispersal seed predation reduces the number of seeds from the soil surface before the seeds contribute to the seedbank.

Ecological Indicators, 2022 During the restoration of secondary forests in Northeast China, it is critically important to promote seed recruitment of Korean pine (Pinus koraiensis), which is highly dependent on rodents and significantly affected by spatially heterogeneous ...

Agronomy, 2022 Weeds are one group of pests that significantly reduce crop yields and qualities, while herbicide use poses a risk to human health and environment. Weed seed predation has been identified as a potential biocontrol approach offering sustainable weed ...
