Plant survival and keystone pollinator species in stochastic coextinction models: role of intrinsic dependence on animal-pollination [PDF]
Scientific Reports 7, 6915 (2017), 2017 Coextinction models are useful to understand community robustness to species loss and resilience to disturbances. We simulated pollinator extinctions in pollination networks by using a hybrid model that combined a recently developed stochastic coextinction model (SCM) for plant extinctions and a topological model (TCM) for animal extinctions. Our model

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

Simulation-based Modelling of Growth and Pollination of Greenhouse Strawberry [PDF]
arXiv, 2022 The cultivated strawberry Fragaria ananassa Duch. is widely planted in greenhouses in China. Its production heavily depends on pollination services. Compared with artificial pollination, bee pollination can significantly improve fruit quality and save considerable labor requirement.

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.

Robotic Pollination of Apples in Commercial Orchards [PDF]
arXiv, 2023 This research presents a novel, robotic pollination system designed for targeted pollination of apple flowers in modern fruiting wall orchards. Developed in response to the challenges of global colony collapse disorder, climate change, and the need for sustainable alternatives to traditional pollinators, the system utilizes a commercial manipulator, a ...

Ecology and Evolution, 2023 Reproductive isolation plays an important role in maintaining the species integrity of sympatric close relatives. For sympatric Arisaema species, interspecific gene flow is expected to be effectively prevented by pre‐pollination barriers, particularly ...

The Indian Journal of Agricultural Sciences, 2014 Due to lack of stable male sterile system in okra [Abelmoschus esculentus (L.) Moench], hybrid seed production is still dependant on hand emasculation and pollination which is troublesome and labour intensive. Five hybridization techniques, viz.

Competition-induced increase of species abundance in mutualistic networks [PDF]
JSTAT (2019) 033502, 2018 Nutrients from a flowering plant are shared by its pollinators, giving rise to competition in the latter. Such exploitative competition of pollinators can limit their abundance and affect the global organization of the mutualistic partnership in the plant-pollinator mutualistic community.

Pesticide Mediated Critical Transition in Plant-Pollinator Networks [PDF]
arXiv, 2023 Mutually beneficial interactions between plant and pollinators play an essential role in the biodiversity, stability of the ecosystem and crop production. Despite their immense importance, rapid decline events of pollinators are common worldwide in past decades.

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
