Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
Both the insect pollinators and plant populations will eventually become extinct due to the uneven and confusing connection that is caused by the change of climate. [31] Flowering times in British plants for example have changed, leading to annual plants flowering earlier than perennials , and insect pollinated plants flowering earlier than ...
A survey by the University of Maryland and Auburn University published in 2023 found the number of United States honey bee colonies "remained relatively stable" although 48% of colonies were lost in the year that ended April 1, 2023, with a 12-year average annual mortality rate of 39.6%. The previous year (2021–2022) the loss was 39% and the ...
Primary metabolism in a plant comprises all metabolic pathways that are essential to the plant's survival. Primary metabolites are compounds that are directly involved in the growth and development of a plant whereas secondary metabolites are compounds produced in other metabolic pathways that, although important, are not essential to the functioning of the plant.

Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. [1] Pollinating agents can be animals such as insects, for example beetles or butterflies; birds, and bats; water; wind; and even plants themselves.
Prosecutors have petitioned the court to prevent the release of Adrian Jerry Gonzalez, who pleaded guilty to all charges in the death of Madyson 'Maddy' Middleton. In 2015, a rape and murder of an ...
A foraging pollinator of a species in the Lupinus genus. At the top of the inflorescence are rewarding flowers at anthesis where the spot on the banner petal is yellow. Towards the bottom of the inflorescence there are older purple flowers that are typically avoided by pollinators presumably because they contain less pollen and nectar. [8]
