The identification of floral visitation by pollinators provides an opportunity to improve our understanding the fine-scale ecological interactions between plants and pollinators, contributing biodiversity conservation promoting ecosystem health. In this review, we outline various methods which can be used identify visitation, including plant-focused insect-focused methods. We reviewed literatur...
Cover crops are typically grown during the summer in Florida’s organic vegetable systems, where they can affect nutrient cycling, soil health, and pests/pollinators. We compared effects of five cover a weedy fallow on marketable yields cycling phosphorus, potassium, carbon. Weed, nematode, insect pollinator abundance were also monitored to measure any secondary impacts cropping. included monocu...
Abstract Pollinators are threatened worldwide and strategies measures to support their conservation proliferating. Among them, the approach “Farming with Alternative Pollinators” (FAP) aims pollinators by seeding strips of pollinator-attracting cultivated plants surrounding crops, simultaneously providing income farmer. In this study we assessed whether supports pollinator diversity in agro-eco...
Abstract Agricultural production is increasingly viewed as more than a source of food, feed, fiber and fuel, but also system interdependent biotic abiotic components that interact to produce ecosystem services disservices. Weeds insects are commonly non-desirable agroecosystems should be managed. However, weeds can provide benefits cropping systems, such providing resources habitat pollinators ...
BACKGROUND AND AIMS In the UK, the flowers of fruit-bearing hedgerow plants provide a succession of pollen and nectar for flower-visiting insects for much of the year. The fruits of hedgerow plants are a source of winter food for frugivorous birds on farmland. It is unclear whether recent declines in pollinator populations are likely to threaten fruit-set and hence food supply for birds. The pr...
Understanding the mechanisms by which non-native plants can attract pollinators in their new geographical zones is important because such species infiltrate native communities and disrupt ecological interactions. Despite large number of studies assessing how invasive impact plant–pollinator interactions, specific comparison pollination interactions between plant pairs has received much less att...
Flowers allure potential pollinators by displaying attractive colour patterns, which are generally created by their petal arrangement and pigmentation. In addition to the pigmentary coloration, in certain cases reflecting surface structures may contribute to the flowers' appearance. For instance, a flower petal surface with periodic striations, acting as a grating reflector, can create an angle...
The evolution of floral zygomorphy is an important innovation in flowering plants and is thought to arise principally from specialization on various insect pollinators. Floral morphology of neotropical Malpighiaceae is distinctive and highly conserved, especially with regard to symmetry, and is thought to be caused by selection by its oil-bee pollinators. We sought to characterize the genetic b...
Echium (Echium plantagineum L.) is an alternative oilseed crop in summer-wet temperate regions that provides floral resources to pollinators. Its seed oil is rich in omega-3 fatty acids, such as stearidonic acid, which is desired highly by the cosmetic industry. Seeds were sown in field plots over three years in western Minnesota in spring (early-sown) or early summer (late-sown), and flower ab...
Despite the economic importance of Crambe abyssinica, the present study is the first report on bees that occur with this species, and could aid in developing alternative methods for controlling insect pests without seriously impacting pollinators. The present study examined the following questions: (1) Which species are potential pollinators of C. abyssinica? (2) How do environmental conditions...
