The macroeconomic cost of catastrophic pollinator declines [PDF]

open access: yes, 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 Pollinating Tools for Actinidia Crops

open access: yesBiology and Life Sciences Forum, 2023
Pollination is a crucial reproductive process that underpins crop yield and quality as well as sustains other ecosystem services essential for our planet’s life. Insects are the largest group of pollinators, particularly bees, handling the pollination of

High cross-pollination rate of Greek oregano (O. vulgare ssp. hirtum) with Common oregano (O. vulgare ssp. vulgare) under open field conditions as revealed by microsatellite marker analysis

open access: yesBiotechnology & Biotechnological Equipment, 2023
We studied the mode of pollination in Greek oregano (Origanum vulgare ssp. hirtum) under both controlled and open pollination conditions. When grown indoors without the presence of insects, Greek oregano plants did not develop any seeds, indicating a low

Standardization of cost effective hybridization technique for hybrid seed production in okra (Abelmoschus esculentus)

open access: yesThe 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.

Post‐pollination barriers contribute to coexistence of partially pollinator‐sharing Arisaema species (Araceae)

open access: yesEcology 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 ...

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

open access: yes, 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

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Porosity Engineering of MXene Architectures: Toward High‐Performance Aqueous Electrochemical Energy Storage

open access: yesAdvanced Materials, EarlyView.
This review systematically summarizes recent advances in porosity engineering of MXenes, with a focused discussion on their structure‐governed energy storage properties. A critical analysis of structure–property relationships is presented across alkali‐ion batteries, multivalent‐ion batteries, and supercapacitors.

Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]

open access: yes, 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

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

open access: yesAdvanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...
