Frugivore

A frugivore is a fruit eater. It can be any type of herbivore or omnivore where fruit is a preferred food type. Because approximately 20 percent of all mammalian herbivores also eat fruit, frugivory is considered to be common among mammals.〔Danell, K. and R. Bergstrom. 2002. Mammalian herbivory in terrestrial environments.in C. M. Herrera and O. Pellmyr, editors. Plant-Animal Interactions. Blackwell Publishing, Oxford, UK.〕 Since frugivores eat large volumes of fruit, they are highly dependent on the abundance and nutritional composition of fruits. Frugivores can either benefit fruit-producing plants by dispersing seeds, or they can negatively affect plants by digesting seeds along with the fruits. When both the fruit-producing plant and the frugivore species benefit by fruit-eating behavior, their interaction is called a mutualism.
==Frugivore seed dispersal==
Seed dispersal is important for plants because it allows their progeny to move away from their parents over time. The advantages of seed dispersal may have led to the evolution of fleshy fruits, which entice animals to eat the fruits and move the plants seeds from place to place. While many fruit-producing plant species would not disperse far without frugivores, they can usually germinate even if they fall to the ground directly below the parent plant.
Many types of animals are seed dispersers. Mammal and bird species represent the majority of seed-dispersing species. However, frugivorous tortoises, lizards, amphibians, and even fish also disperse seeds.〔Herrera, C. M. 2002. Seed Dispersal by vertebrates.in C. M. Herrera and O. Pellmyr, editors. Plant-Animal Interactions. Blackwell Publishing, Oxford, UK.〕 While frugivores and fruit-producing plant species are worldwide, there is some evidence that tropical forests have more frugivore seed dispersers than the temperate zone.
