Fruit color preference by birds and applications to ecological restoration

摘要: Ecological restoration aims to retrieve not only the structure but also functionality of ecosystems. Frugivorous birds may play an important role in this process due their efficiency seed dispersal. Color perception these animals is highly developed, and then colors fleshy fruits provide clues for choosing plant species plans. This study integrate bird color preferences degraded areas, with objective evaluate potential attractiveness by colored fruits. We carried out experiment 384 artificial made edible modeling clay following colors: black, blue, green red, 96 each six sites, including four restored areas two second-growth forest fragments. tested possible effect light intensity on fruit consumption color. A total 120 (38.6%) were assumed be consumed birds, varied response location incidence. Consumption black blue was related site chance. Notwithstanding, red significantly more than any other colors, emphasizing preference regardless location. Enrichment shade tolerant shrubs or alternative way manage established restorations. In recently new restorations, one introduce pioneer short-lived which have fruits, those having ones.
