An improved optimization technique for estimation of solar photovoltaic parameters [PDF]

, 2017
The nonlinear current vs voltage (I-V) characteristics of solar PV make its modelling difficult. Optimization techniques are the best tool for identifying the parameters of nonlinear models.

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.

Importance of bee pollination for cotton production in conventional and organic farms in Brazil

Journal of Pollination Ecology, 2014
This study aimed to evaluate the importance of wild bee and feral honeybee visits for cotton production on conventional and organic farms. Experiments were conducted in Brazil, on a conventional cotton farm in Mato Grosso state in the Amazon biome and on

Nectar production and pollination in peach

International Journal of Horticultural Science, 2000
Observations were made at two growing sites, Siófok and Szatymaz, in the years 1998 and 1999, on 16 peach varieties. The production of nectar was measured, the foraging behaviour of bees, fruit set and the effect of exclusion of bee visits for different ...

Flight of the bumble bee: Buzzes predict pollination services.

PLoS ONE, 2017
Multiple interacting factors drive recent declines in wild and managed bees, threatening their pollination services. Widespread and intensive monitoring could lead to more effective management of wild and managed bees.

Non-bee insects are important contributors to global crop pollination [PDF]

, 2015
Wild and managed bees are well documented as effective pollinators of global crops of economic importance. However, the contributions by pollinators other than bees have been little explored despite their potential to contribute to crop production and ...

Pollen samples from a bumble bee (Hymenoptera: Apidae) collection show historic foraging on introduced and native plants in the South Island of New Zealand.

PLoS ONE, 2022
Historic pollination networks are important to understand interactions between different plant and pollinator species, as well as to differentiate between causes and consequences of present insect population decline.

What's in a name? Challenging the commodification of pollination through the diverse economies of 'Bee Cities'

Journal of Political Ecology, 2021
One million species are threatened with extinction globally,including more than half of the native bee species in North America. In Canada,as of July 2020, 42 municipalities have signed a resolution to commit to the standards of the Bee City Canada ...
