Seed harvesting is influenced by associational effects in mixed seed neighbourhoods, not just by seed density

Functional Ecology, 2013
Summary Rodents frequently forage in a density‐dependent manner, increasing harvesting in patches with greater seed densities. Although seldom considered, seed harvesting may also depend on the species identities of other individuals in the seed neighbourhood. When the seed harvest of a focal species increases in association with another seed species,

Seed density affects post‐dispersal seed predation: evidence from a seed removal experiment of 62 species

Integrative Zoology, 2020
AbstractPost‐dispersal seed predation plays an important role in plant demography and biodiversity maintenance. However, the effects of seed density on seed predation from previous studies have been inconsistent. We dissected the effects of density on the 2‐step processes of seed predation using 101 520 seeds from 62 plant species in an alpine pine ...

Optimizing seed rate and stem density for seed potato production

The Journal of Agricultural Science, 1985
Previous investigations (e.g. Bates, 1935; Singh, 1952; Bremner & Taha, 1966; Sharpe & Dent, 1968) established that increase in the size of potato seed planted and decrease in inter-sett spaoing increased the number of stems and of tubers, resulting in yield advantage generally, but reduced tuber size in the produce.

Seed size–seed number trade‐offs: influence of seed size on the density of fire‐stimulated persistent soil seed banks

American Journal of Botany, 2022
AbstractPremiseDoes the seed size–seed number allocation trade‐off model apply to long‐term persistent soil seed banks? This trade‐off between seed size versus number of seeds produced is usually applied at a single population on an annual basis. Our question is how this model might apply to close relatives that produce dormant seed forming long‐term ...

Densities of melon seeds, kernels and hulls

Journal of Food Engineering, 1989
Abstract True density, bulk density and apparent density of the seeds, kernels and hulls of commercial varieties of muskmelon, longmelon and watermelon were determined. There is a significant difference between the apparent densities of kernels and of seeds.

SEED PREDATION AND SELECTION EXERTED BY A SEED PREDATOR INFLUENCE SUBALPINE TREE DENSITIES

Ecology, 2008
Strongly interacting species often have pronounced direct and indirect effects on other species. Here we focus of the effects of pine squirrels (Tamiasciurus spp.), which are a dominant pre-dispersal seed predator of many conifers including limber pines (Pinus flexilis) and whitebark pines (P. albicaulis).
