Competitive interactions between neotropical pollinators and africanized honey bees
Science (New York, N.Y.)
|September 15, 1978
Summary
Africanized honey bees may threaten native pollinators. Their increased flower visitation led to reduced abundance and resource harvesting by stingless bees, potentially causing Neotropical pollinator declines.
Area of Science:
- Ecology
- Entomology
- Conservation Biology
Background:
- Africanized honey bees (AHB) are a hybrid of European and African honey bees.
- AHBs are known to be highly adaptable and aggressive.
- There is concern that AHBs may displace native pollinators.
Purpose of the Study:
- To investigate the impact of Africanized honey bee introduction on native pollinator populations.
- To assess resource competition between AHBs and native pollinators.
Main Methods:
- Experimental introduction of Africanized honey bee hives near flowering plants.
- Observation and quantification of visitation rates by AHBs and native stingless bees.
- Assessment of resource availability and harvesting by both bee types.
Main Results:
- Increased Africanized honey bee visitation correlated with decreased abundance of stingless bees.
- Stingless bees harvested fewer resources in the presence of AHBs.
- Evidence of shifts in resource use due to AHB colonization.
Conclusions:
- Africanized honey bees can negatively impact native pollinator populations.
- Resource competition with AHBs may lead to population declines in Neotropical pollinators.
- Conservation strategies may be needed to protect native pollinators from invasive AHBs.

02:40Pollination and Flower Structure
Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.
02:39Predator-Prey Interactions
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.Although predation is commonly associated with carnivory, for...
00:58Symbiosis
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
01:21Frequency-dependent Selection
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...
00:53Migration
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
02:29Hybrid Zones
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.Gene flow and natural selection are evolutionary mechanisms that shape the outcome of a hybrid zone. Gene flow...
