Research reveals dramatic shifts in pollinators across the last century, with hoverflies and moths becoming less frequent visitors to flowers, replaced by flies of the genus Thricops. The findings suggest that plants may be able to compensate for these losses, but changes in insect communities could lead to reduced pollination services.
A new study finds that inadequate pollination leads to a 3-5% loss of fruit, vegetable, and nut production, resulting in 427,000 excess deaths annually from lost healthy food consumption. The health burden is greater in middle- and higher-income countries with high rates of non-communicable diseases.
Genetic analysis confirms Asian hornet's origins, linking it to a single mated queen that arrived in France in 2004. The finding raises concerns about future invasions despite the species' limited suitability for Ireland's climate.
A team of researchers at the University of Tokyo has discovered a newly found trait in the Causonis japonica flower, which changes color depending on its maturation cycle and then reverses. The pigments involved are related to nutrient-rich colorful vegetables, suggesting potential downstream applications in improving nutrient yields.
Researchers at the University of Bristol found that social bees have larger foraging ranges due to traits like body size, colony size, communication, and flower constancy. This has significant implications for predicting pollination services and creating effective conservation strategies for bees and plants.
Researchers found that fertilizers change the electric field surrounding a flower, affecting bees' ability to navigate and feed. This alteration lasts for up to 25 minutes and can persist beyond a single use of chemicals.
Researchers found that shorter flower petals reduce the transmission of a harmful pathogen, increasing larval production and bee health. Planting flowers with trimmed corollas or even distribution of nectar also supports bee well-being.
A new study reveals the Atacama desert's 'blooming desert' phenomenon is characterized by a high level of variability in flower colors and patterns, which are invisible to human eyes. However, pollinators such as bees and wasps perceive this diversity due to their unique color sensitivity.
A new study found that a rare Wyoming sagebrush species, Laramie chickensage, is primarily pollinated by bees. The research, led by University of Wyoming graduate student Madison Crawford, shows that 61% of viable seeds produced by the plants were from insect pollination.
A study by Finnish researchers found that exposure to the herbicide glyphosate impairs bumblebees' fine color vision, affecting their ability to learn and remember connections between colors and tastes. This weakened color vision can severely impact bumblebees' foraging and nesting success.
New research from the University of East Anglia reveals that wild bees are actively foraging in the sunlit woodland canopy, particularly among Sycamore trees. A diverse community of wild bees was found to thrive in this habitat, with nectar and pollen-rich trees providing essential food sources.
A new study found that mobile stamens on flowers help reduce the time insects linger on flowers, decreasing nectar consumption while increasing pollen transport efficiency. This allows for more efficient pollination, ultimately benefiting plant reproductive success.
A new study confirms that plants can adapt to diurnal or nocturnal pollinators through evolutionary changes. In a Costa Rican plant species, insect pests were found to exclusively pollinate during the day, using a previously unknown scent compound.
Excess ground-level ozone damages plant foliage, alters flowering patterns, and blocks pollinators' access to flowers. Ozone also disrupts plant-pollinator communication through altered chemical signatures.
Researchers found that hedges and perennial flower strips complement each other to support wild bees in orchards, with species visiting flowers at different times of the year. Perennial flower strips were more beneficial for wild bees than annual strips, attracting different bee communities over time.
Higher temperatures shorten the lifespan of fig wasps, making it difficult for them to pollinate fig trees. This could have major consequences for animals in tropical forests that rely on figs as a food source.
Researchers found that insects have a weak ability to acclimate to high temperatures, with only small compensations of 10-15°C. Juvenile insects show greater resilience, but this may be limited to specific critical periods. The study highlights the need for further research on insect responses to climate change.
A recent study by the University of Exeter reveals that honeybees rely on both color and pattern to identify flowers. The researchers found that bees can effectively distinguish between different flowers using a combination of these elements, suggesting that flowers don't need to evolve many different petal colors.
Researchers found that a species of red seaweed uses an isopod crustacean to transfer its male gametes for fertilization, presenting a new class of animal-mediated male gamete movement. This discovery expands the concept of 'pollination' beyond seed plants.
The white egret orchid's unique petal shape supports the hawkmoth pollinator, leading to higher healthy seed production. The research found that intact plants produced more seeds than those with the fringed petal removed.
Researchers at the University of Exeter are using satellites and drones to track the availability of flowers for pollinators. This technology could be combined with behavioral studies to better understand the impact of human activity on pollinator habitats, leading to more effective conservation efforts.
New research shows that bumblebees waste no time enjoying flowers but instead learn the bare minimum about where to land and find food. Bees extract just the necessary information from artificial flowers, suggesting a simple, low-effort form of learning is sufficient in some situations.
Research reveals hoverflies use a time-compensated sun compass to orientate during autumn migration, adjusting course based on sun's position and time of day. This navigation technique helps the insects maintain an efficient southern route despite flying on sunny days.
Researchers from Göttingen and Hohenheim found hand pollination used worldwide for 20 crops, including apples and vanillas. The method can reduce losses and improve crop quality, but also brings challenges due to labor intensity and cost.
A recent study reveals that global agriculture is shifting towards monocultures, threatening food security and the livelihoods of millions. The majority of the world's fastest-growing crops rely on pollinators, which are under threat due to pesticides and habitat loss.
Biologists at UCSD discovered red and yellow monkeyflowers have distinct pollinators, with hummingbirds preferred for the red form and hawkmoths for the yellow. The shift in flower color is likely due to natural selection by these different pollinators.
A study by Cornell University researchers found that managed honey bees pollinate over 50 crops worth $14.6 billion per year, a 36.3% increase from 1989. The contribution of honey bees to US agriculture is crucial for food production and security.
Research reveals that nectar robbing by bumble bees reduces pollen transfer and pollination success in the scarlet gilia plant. The study found that high robbing rates attract fewer pollinators, leading to decreased reproductive success.
Wild honeybee populations have collapsed due to a combination of factors, including harsh winters, wet springs, and blood-sucking mites. As a result, small and medium-sized fruit and vegetable growers will be hardest hit, leading to smaller yields and lower quality produce.
