Cash, Credit, or Kin? Financing Pathways and the Uneven Sustainability of Off‐Grid Solar Electrification in Tanzania and Malawi

open access: yesSustainable Development, EarlyView.
ABSTRACT Solar home systems (SHSs) are celebrated as a technological antidote to sub–Saharan Africa's chronic electricity deficits, yet the financial and social mechanisms that move them from warehouse to household remain underexplored. Drawing on 157 interviews with SHS owners in Tanzania and Malawi, this study examines the financial pathways used to ...

Demographic analysis of behavioral reactions of African bush elephants to a synthetic honey bee alarm pheromone blend

open access: yesWildlife Biology, EarlyView.
Human–elephant conflict situations continue to be a growing conservation issue. Conflict situations typically arise as the result of elephants traversing places with infrastructure where they become disruptive to human activities. Developing passive options for managing elephant movement and reducing human–elephant conflict situations is a conservation

Modeling Honey Bee Populations

open access: yesPLOS ONE, 2015
Eusocial honey bee populations (Apis mellifera) employ an age stratification organization of egg, larvae, pupae, hive bees and foraging bees. Understanding the recent decline in honey bee colonies hinges on understanding the factors that impact each of these different age castes.

Isolating the effects of floral temperature on visitation and behaviour of wild bee and fly pollinators

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flower temperature impacts pollinator choice in laboratory settings and the foraging behaviour of bees in natural populations. However, the direct effects of floral temperature on animal pollination in field conditions are difficult to isolate from other pollinator ...

Therapeutic Properties of Stingless Bee Honey in Comparison with European Bee Honey

open access: yesAdvances in Pharmacological Sciences, 2018
Both honeybees (Apis spp.) and stingless bees (Trigona spp.) produce honeys with high nutritional and therapeutics value. Until recently, the information regarding potential health benefits of stingless bee honey (SBH) in medical databases is still scarce as compared to the common European bee honey (EBH) which is well known for their properties as ...

Negative ecological impacts of honeybees begin at densities below recommended levels for crop pollination

open access: yesJournal of Applied Ecology, EarlyView.
The ecological consequences of high‐density honeybee management are significant, calling for a re‐evaluation of pollination strategies in agricultural landscapes. Setting evidence‐based hive density guidelines is critical to balancing agricultural productivity with the conservation of native pollinator communities and the maintenance of healthy ...

The Molecular Properties of Honey Bee Acetylcholinesterase Reveal Opportunities to Avoid Off-Target Effects in Insecticide Discovery. [PDF]

open access: yesChemistry
The structure, dynamics, and kinetics of the essential enzyme acetylcholinesterase (AChE) of honey bee have been studied and compared to AChEs in mosquitoes and mammalians. Profiling of the active sites with selected substrates and AChE inhibitors revealed dramatic differences between the species.
