The effects of urbanisation on pollinators and pollination: A meta-analysis
Ecology Letters, 2022 Urbanisation is increasing worldwide, with major impacts on biodiversity, species interactions and ecosystem functioning. Pollination is an ecosystem function vital for terrestrial ecosystems and food security, however, the processes underlying the patterns of pollinator diversity and the ecosystem services they provide in cities have seldom been ...

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.

Toward in vitro fertilization in Brachiaria spp. [PDF]
, 2010 Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

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 ...

The macroeconomic cost of catastrophic pollinator declines [PDF]
, 2016 We develop a computable general equilibrium (CGE) approach to assess the macroeconomic impacts of productivity shocks due to catastrophic losses of pollination ecosystem services at global and regional scales.

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

Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]
, 2018 Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from

Pollination ecology and breeding system of two Calceolaria species in Chile [PDF]
, 2014 Indexación: Web of Science; Scielo.Many angiosperms are exclusively dependent on pollinators for its reproduction (Matallana et al.2010; Arroyo et al. 2006).

Pollination Efficiency and the Evolution of Specialized Deceptive Pollination Systems [PDF]
The American Naturalist, 2010 The ultimate causes of evolution of highly specialized pollination systems are little understood. We investigated the relationship between specialization and pollination efficiency, defined as the proportion of pollinated flowers relative to those that experienced pollen removal, using orchids with different pollination strategies as a model system ...

Floristic response to urbanization: Filtering of the bioregional flora in Indianapolis, Indiana, USA [PDF]
, 2017 PREMISE OF THE STUDY: Globally, urban plant populations are becoming increasingly important, as these plants play a vital role in ameliorating effects of ecosystem disturbance and climate change.
