We investigated if the marsupial Dromiciops gliroides (Microbiotheriidae) is a legitimate seed disperser of Ugni molinae (Myrtaceae). We compared the germination rate of defecated and not-defecated seeds. The results show that defecated seeds are viable and show a high germination rate than no-defecated seeds. We conclude that D. gliroides is a legitimate seed disperser of U. molinae, and it may affect their reproductive success. These results are the first evidence of a seed disperser for U. molinae, and also support the proposal that D. gliroides have an important role as a seed disperser in the temperate forest of southern South America. |

Feeding on saline marine foods may be especially challenging for passerine birds that lack functional salt glands and have a limited ability to concentrate urine. To reduce the salt load imposed by consumption of marine food these birds may select food with low salt contents and/or increase their intake of freshwater. The genus Cinclodes is particular among passerines because it includes species that inhabit both inland and maritime shores. We analyzed the diet of Cinclodes nigrofumosus and explored the possible relationships between dietary composition and salt load at mesic and arid coastal sites of Chile. From a biogeographical perspective, we hypothesized that freshwater availability is critical to the relationship between diet composition and osmotic... |
