Paper Summary:
This paper examines the importance of pollination services. As the author explains, the health of ecosystems and agriculture worldwide depends on pollinating services performed by particular pollinators. This paper evaluates the importance of pollinators, provides statistical evidence for vertebrate and invertebrate pollinator decline and examines causes and consequences of pollinator decline. The paper also demonstrates the consequences of pollinator decline in terms of plant pollinator interactions and corresponding research, including figures. The paper concludes that that the functional diversity of the pollination network is critical to ecosystem sustainability and productivity.

From the Paper:
"Green plants represent the primary food source for a large portion of the worlds living biota. Many plants reproduce sexually and require pollination agents to ensure genetic diversity and other adaptive advantages through cross-pollination. During the search for nectar, pollen, oil, or mates, pollinators transfer pollen from male anthers to female stigmas and hence perform pollination (Cane, 2001). Due to co-evolution among angiosperms and pollinators, many primary pollinator- plant relationships are highly specific. Therefore the health of ecosystems and agriculture worldwide depends on pollinating services performed by particular pollinators. In recent decades human activates have decimated biodiversity in many different species-rich groups, including invertebrates (Cane, 2001). Declines have been recorded in many groups of pollinators including: insects, bats, birds and mammals. This decline represents less frequent flower visitation, gradual decrease of seed and fruit production, and reproductive losses in additional taxa within the community and could eventually disrupt community function (Cane, 2001)."
