The declines in abundance and diversity of insect pollinators over the twentieth century have been documented in highly industrialized regions of the world, particularly northwestern Europe and eastern North America. [16] [17] [18] Colony collapse disorder has attracted much public attention. According to a 2013 blog the winter losses of ...
With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture.Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging ...
These fruits and vegetables are important commercial products, but are also a source of food for wild animals. So pollinators "hold entire ecosystems together," Watson said.
It is important in horticulture and agriculture, because fruiting is dependent on fertilisation: the result of pollination. The study of pollination by insects is known as anthecology . There are also studies in economics that look at the positives and negatives of pollination, focused on bees, and how the process affects the pollinators ...
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
As pollinators decline, agricultural yields do as well. [10] Without pollination, the main sources of human nutrition will suffer. [ 11 ] [ 12 ] Further, it is not just crops that are in danger, because 80-95% of non-crop plant species require some form of pollination as well. [ 13 ]
Honeybees and bumblebees can also act as pollinators of crop species. Although pollination can be achieved during pollen transport via wind, a large amount is also achieved via insect, specifically bee transport. In 1986, there was an estimated 17,000 million worth of crops that were solely pollinated by insects in the United States. [21]
