2011年11月16日 · While this has been documented with tropical rodents in South America like agoutis and acouchis, a new study in Biotropica documents the first successful seed dispersal by an African rodent: the Kivu giant pouched rat (Cricetomys …

2013年8月5日 · Seed-caching rodents play a key role in the ecology of seed dispersal by not only consuming but also dispersing seeds. Rodent foraging behaviour is usually framed within optimal models, which predict that their decisions should maximize food intake and …

2016年7月22日 · In agricultural landscapes, rodents are considered important seed predators, thereby potentially providing regulating ecosystem services in terms of biological weed control. However, their potential to disperse seeds endozoochorously is largely unknown.

In summary, giant kangaroo rats showed selective foraging of one non-native grass, but not greater foraging of native seeds overall. They also showed changing nutritional preferences as they harvested seeds further from their burrow.

2008年7月26日 · In general, our studies based on enclosure experiments demonstrate that a high seed abundance stimulates L. edwardsi to disperse and scatter-hoard more seeds of C. oleifera at the individual level, and also stimulates the rat to eat fewer seeds of C. oleifera.

2021年8月1日 · Novel diplochory between non-native rats and native bats enhances seed dispersal. The unusual fruit structure facilitates seed dispersal by seed-eating rats. Non-native rats can have positive impacts on seed dispersal processes. Many oceanic islands lacked mammalian seed predators until humans introduced rats (Rattus spp.).

2022年4月5日 · If you’re wondering if the bird seed is attracting rats, and how to stop it, you’re not alone. We wondered the same thing, so we compiled data from 9 months of rodent services at houses with and without bird feeders.

In this study, we investigated the effects of seed abundance (by simulating mast seeding and non-mast seeding) on the removal, consumption and scatter-hoarding of seeds of Camellia oleifera (Theaceae) by Edward's rat Leopoldamys edwardsi (Muridae) in seminatural enclosures in southwest China.

Feeding trials in which fruits and seeds were offered to wild-caught rats were used to assess the effects of the most common rat, the black rat (R. rattus), on 25 of the most problematic invasive plant species in the Hawaiian Islands.

2025年1月10日 · Bird Seed Attracts Rats: Unattended bird seed can draw unwanted rodent visitors, as rats are opportunistic feeders that thrive on easy food sources like spilled or leftover seeds.
