Review: Pollination, Pollinated and Pollinators Interaction in Pakistan

Journal of Bioresource Management, 2014
The agriculture sector is important in the overall economy and export earnings of Pakistan. Pollination is an essential ecosystem service that depends on symbiosis between species, the pollinated and the pollinator. Animal mediated pollination contributes to the sexual production of over 90% species of modern angiosperms.

Dufour’s gland analysis reveals caste and physiology specific signals in Bombus impatiens

Scientific Reports, 2021
Reproductive division of labor in insect societies is regulated through multiple concurrent mechanisms, primarily chemical and behavioral. Here, we examined if the Dufour’s gland secretion in the primitively eusocial bumble bee Bombus impatiens signals ...

Pollination by hoverflies in the Anthropocene [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2020
Pollinator declines, changes in land use and climate-induced shifts in phenology have the potential to seriously affect ecosystem function and food security by disrupting pollination services provided by insects. Much of the current research focuses on bees, or groups other insects together as ‘non-bee pollinators’, obscuring the relative contribution ...

Plant species richness and sunlight exposure increase pollinator attraction to pollinator gardens

Ecosphere, 2022
Evidence documenting the decline of insect populations is accumulating. Efforts have increased to mitigate pollinator losses by establishing gardens to support pollinator diversity.

Effects of fire on pollinators and pollination [PDF]

Journal of Applied Ecology, 2016
Summary Increased incidence of landscape fire and pollinator declines with co‐extinctions of dependent plant species are both globally significant. Fire can alter species distributions, but its effects on plant–pollinator interactions are poorly understood so its present and future role in coupled plant–pollinator declines cannot be assessed.

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]

, 2008
1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

Pollinator individual‐based networks reveal the specialized plant–pollinator mutualism in two biodiverse communities

Ecology and Evolution, 2021
Generalization of pollination systems is widely accepted by ecologists in the studies of plant–pollinator interaction networks at the community level, but the degree of generalization of pollination networks remains largely unknown at the individual ...

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

Hairiness: the missing link between pollinators and pollination [PDF]

PeerJ, 2016
BackgroundFunctional traits are the primary biotic component driving organism influence on ecosystem functions; in consequence, traits are widely used in ecological research. However, most animal trait-based studies use easy-to-measure characteristics of species that are at best only weakly associated with functions.

Abundance of Pollinator Insect (Forcipomyia Spp .) of Cocoa Under Some Shade Trees [PDF]

, 2016
Cocoa production is affected by cocoa flowering and fruiting. The factor affects fruit seeting is pollinator agent such as Forcipomyia spp. Until now, information concerning population dynamics of Forcipomyia in some models of cocoa shading trees remains
