| ABSTRACT: The objective of this study was to evaluate endozoochory dispersal, recuperation, and germination of weedy rice (Oryza sativa L.) and barnyardgrass (Echinochloa crus-galli L.) seeds passed through the digestive system of cattle. The experiment was divided into two phases: first, the daily seed recuperation rate was determined after passing through the digestive system of six steers. Each animal was dosed individually with 1000 weedy rice seeds and 13,818 barnyardgrass seeds, and these seeds were subsequently collected from feces. In the second phase, seed germination and emergence rate after passing or not passing through the digestive system of cattle were determined in two types of substrates (fecal plaque and soil) in a 2×2 factorial design.... |

| The fate of Prosopis flexuosa seeds dispersed by cattle is dependant on the spatial pattern of dung deposition and foraging movements. We hypothesised that cattle-use site classes explain the response variables related to seed input and fate of seeds, seedlings and saplings (small plants more than one year old). We defined sites with heavy cattle traffic ("trails" and "periphery of trails"), sites used for resting and foraging ("under Prosopis"), and sites where isolated individuals only walk ("under shrubs" and "bare soil"). Considering the established cattle-use site classes, our specific goals were to quantify and compare: (1) seeds transported in cattle dung; (2) seedlings 10 months after dung deposition; (3) established saplings; and (4) germinated... |

| We investigated whether introduced European rabbit on Robinson Crusoe Island, Chile, has the potential to spread the seeds of the exotic Papaver somniferum (opium poppy) via endozoochory. A total of 1320 rabbit droppings were collected during early autumn in the study area and analyzed in laboratory with binocular magnifying glass. Seeds from six different species were found in the droppings: Papaver somniferum (Papaveraceae), Centaurea melitensis (Asteraceae), Amaranthus sp. (Amarantaceae), Melilotus indicus (Fabaceae), Rumex acetosella (Polygonaceae), and one unidentified species. Poppy seeds were dominant. Most seeds (82%) were destroyed during ingestion, but some of the intact seeds found in pellets remained viable. Germination rate of ingested seeds... |
