Physicochemical characteristics of organic honey samples of africanized honeybees from Paraná River islands. [PDF]

open access: yes, 2011
This research was carried out to evaluate the physicochemical composition of organic honey in Paraná River islands, in Porto Brasílio, State of Paraná. Honey was harvested directly from super of the colonies in three apiaries spread in the Floresta and ...

Feromoni medonosne pčele (Apis mellifera L.)

open access: yesStočarstvo, 2017
Podjelu uloga između članova pčelinje zajednice, kao i funkcioniranje pčelinje zajednice omogućuje savršena komunikacija, a ona se kod pčela odvija pomoću pčelinjeg plesa i najvećim dijelom putem feromona. Feromoni u pčelinjoj zajednici imaju ulogu spajanja pčela kao jedinki u jednu kohezivnu zajednicu, tzv. superorganizam.

Colony aggregations in Apis mellifera L [PDF]

open access: yesApidologie, 1995
Natural aggregations of A mellifera L have not been reported. However, in the related species A dorsata, aggregations of colonies are common. A survey of the spatial distribution of feral A mellifera colonies showed that they too can be markedly clumped, with up to 10 colonies/ha.

Genetic integrity of the Dark European honey bee (Apis mellifera mellifera) from protected populations: a genome-wide assessment using SNPs and mtDNA sequence data [PDF]

open access: yes, 2014
The recognition that the Dark European honey bee, Apis mellifera mellifera, is increasingly threatened in its native range has led to the establishment of conservation programmes and protected areas throughout western Europe.

Honey bees (Apis mellifera spp.) respond to increased aluminum exposure in their foraging choice, motility, and circadian rhythmicity.

open access: yesPLoS ONE, 2019
Aluminum is increasingly globally bioavailable with acidification from industrial emissions and poor mining practices. This bioavailability increases uptake by flora, contaminating products such as fruit, pollen, and nectar. Concentrations of aluminum in

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]

open access: yes, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

Variation in honey bee gut microbial diversity affected by ontogenetic stage, age and geographic location [PDF]

open access: yes, 2015
Social honey bees, Apis mellifera, host a set of distinct microbiota, which is similar across the continents and various honey bee species. Some of these bacteria, such as lactobacilli, have been linked to immunity and defence against pathogens. Pathogen

Differences in pollinator composition, species richness and flower visit abundance between Centaurea jacea (L.) and Leontodon hispidis (L.) in a meadow in Central Slovenia

open access: yesNatura Sloveniae, 2006
In this pilot study, the differences in pollinator composition, species richness and pollinators’ visits between Centaurea jacea and Leontodon hispidis were investigated.

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

open access: yes, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...
