Microplastics and Nanoplastics Effects on Plant–Pollinator Interaction and Pollination Biology

Environmental Science & Technology, 2023
Microplastics and nanoplastics (MNPs) contamination is an emerging environmental and public health concern, and these particles have been reported both in aquatic and terrestrial ecosystems. Recent studies have expanded our understanding of the adverse effects of MNPs pollution on human, terrestrial, and aquatic animals, insects, and plants.

Pollination Biology of Lespedeza davurica

LEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2021
Background: In order to reveal the pollination biological characteristics of Lespedeza davurica, wild L.davurica from eight regions of Shanxi Province was used as test materials to study their floral dynamic, pollen storage and other aspects. Methods: During 2019, the flowering dynamics of wild L.

Orchid pollination biology

Trends in Ecology & Evolution, 1992
Orchids display many unsurpassed floral specializations, as both rewarders and frauds in their interaction with animal pollinators. Accumulating evidence indicates that their floral evolution is driven by pollinator traits and that expenditure for maximized sexual reproduction is parcelled out over their lifetimes in strategies for coping with ...

[Pollination biology of Fritillaria delavayi].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2014
In this study, the processes of pollination ecology of Fritillaria delavayi were investigated to document its reproductive characteristics. Some individuals of F. delavayi could produce seeds under bagging without emasculation (11%), but the rate was significantly lower than that of the natural control (87%).

Butterflies and pollination biology

Proceedings: Animal Sciences, 1984
Most butterflies with the characteristic long proboscis feed on floral nectar, and theHeliconius butterfly feed on pollen as well. They rely mostly on flower colour for locating and identifying the flowers. While foraging on nectar, they carry pollen on their body parts.

Pollination biology ofSymphonia globulifera (Clusiaceae)

Plant Systematics and Evolution, 1996
The pollination biology ofSymphonia globulifera was studied in Central Amazonia, Brazil. As suggested by the bird syndrome of the flowers, these are mainly pollinated by hummingbirds. Occasional visits by other birds, butterflies and more rarely bees, as well as tamarin monkeys were also observed.Trigona bees partly destroy the flower tube to rob ...

Pollination biology ofNierembergia (Solanaceae)

Plant Systematics and Evolution, 1991
A morphological and anatomical description of the floral syndrome ofNierembergia is given, including a survey of the presence of elaiophores in most of its species, chromatography of the floral oils and observations on the pollinator behaviour. The principal pollinators areTapinotaspis spp. includingT.

Pollination Biology in the Callitrichaceae

Systematic Botany, 1992
Callitriche is the only genus in which aerial, water surface, and subsurface pollination systems are all reported. Studies of morphology, flowering phenology, patterns of seed production, and pollen tube growth suggest, however, that geitonogamy is the primary mode of pollination. Typical geitonogamy occurs between the aerial flowers of C. marginata, C.

Back to the past for pollination biology

Current Opinion in Plant Biology, 2011
Manipulations of the interactions between plants and their floral visitors remain the most successful path to an understanding of floral traits, which may have been shaped by both herbivores and pollinators. By using genetic tools in combination with old-fashioned field work the dual protective/advertisement functions of floral traits are being ...

The pollination biology of a pavement plain: pollinator visitation patterns

Oecologia, 1980
The pollination biology of the 20 plant species of a treeless, pavement plain in the San Bernardino Mountains of southern California was studied throughout one flowering season.Several patterns of pollinator activity recorded during the season underline the necessity for noting the activity of all insect pollinators whether specialized, non-specialized,
