Granivory and Granivores in Native Grasslands and Agropyron Cristatum Stands in the Northern Great Plains
… stands was similar to that of native grasslands. Granivores did not prefer native seeds to exotic ones and showed little seed preference. A review of vertebrate granivore seed size preferences revealed that granivores often prefer relatively small seeds in forests and relatively large seeds in …

Influence of fire and habitat on the removal of invasive plant seeds by granivores in longleaf pine savannas
… habitat three growing seasons post-fire. While granivores removed seeds of all four species of exotic plants, E. umbellata experienced significantly higher removal than other species, suggesting that granivores exhibited seed selection. Allowing vertebrate granivores access to seeds enhanced …

Nontarget Avian Use of DRC-1339 Treated Plots During An Experimental Blackbird Control Program in Eastern South Dakota
… 1 df, P<0.001). Eighty-four percent of the avian granivores in the treated plots were observed to be feeding; therefore, it seems likely that the bait may be attracting nontarget granivores. However, extensive mortality searches revealed no nontarget birds sick or dead from DRC-1339 toxicity.

How does surface mining impact surrounding miombo woodland bird communities?
… richness and the species richness of frugivores, granivores, insectivores, woodland and open habitat specialists, breeding and non-breeding species and Zambezian endemics. The results showed that distance from the mine and habitat structure did not significantly explain variation in total species …

Effects of Urbanization on the Avian Community of Oak Woodlands
… at high levels of development), many did not. Granivores and ground-foragers tend to respond positively to urbanization but showed no significant difference here. The focus of this study on oak woodlands may be responsible, as a single habitat type is far more consistent than the whole of an …

The natural history, sensory ecology and biogeography of the seed dispersal of large fruits in Fynbos
… likely reduces predation by visually cued avian granivores. Finally, modeling results suggest that the distributions of both serotinous and scatter-hoarded plants are strongly negatively and positively influenced by more intense seasonal drought and longer fire return interval in the GCFR, …

The Impact of Habitat Alteration on the Population Dynamics of a Declining Woodland Bird in the Mount Lofty Ranges
… change has altered patterns of seed production. Granivores such as the diamond firetail (Stagonopleura guttata) are likely to be affected by such alterations. This species has been declining nationally since large-scale land-clearance prior to 1980. Focussed, species-specific research is required …

The influence of anthropogenic food on bird behaviour and community structure in urban environments
… across South Africa. Carnivores, generalists, granivores and aquatic species exhibited the most pronounced rise in their likelihood of occurrence with increasing income. I also found evidence that the luxury effect was steeper for species endemic to South Africa and for species which were …
