Honey bees are in decline, and the current method of keeping them can be disruptive to a colony. But new designs allow beekeepers to monitor a hive remotely, even sniff out disease and pests.

Growing evidence indicates that European managed honey bees are in decline, but information for Europe remains patchy and localized. Here we compile data from 18 European countries to assess trends in the number of honey bee colonies and beekeepers between 1965 and 2005. We found consistent declines in colony numbers in central European countries and some increases in Mediterranean countries. Beekeeper numbers have declined in all of the European countries examined. Our data support the view that honey bees are in decline at least in some regions, which is probably closely linked to the decreasing number of beekeepers. Our data on colony numbers and beekeepers must, however, be interpreted with caution due to different approaches and socioeconomic factors in the various countries, thereby limiting their comparability. We therefore make specific recommendations for standardized methodologies to be adopted at the national and global level to assist in the future monitoring of honey bees.

Accounting for biodiversity has received increasing attention from the academic accounting community in recent years. Despite a stream of research investigating the quality and quantity of biodiversity reporting in general, no academic research has focused on reporting related to one specific species. This paper explores the quality and quantity of corporate disclosures relating to bees. Society is becoming increasingly concerned about the accelerating fall in bee populations around the world. Colony Collapse Disorder has been spreading through global bee populations since 2006, decimating commercial hives. Concerns are fuelled by fears that pollinators may become extinct which would have dire consequences for the majority of world food production, leaving human pollination, at immense cost, the only alternative. On the basis of these fears, companies as well as other organisations, have started to establish programmes aimed at rejuvenating global bee populations. In this paper we explore the bee-related disclosures provided by a large selection of UK listed companies. We assess the extent to which companies believe they have a role to play in enhancing and protecting bee populations. Further we consider whether corporate accountability in this area derives solely from a business case or whether there is a deeper societal connection with bees as a species which is encouraging companies to protect their survival. The paper investigates the historical and philosophical connection between bees and human beings, for example the ways industrial production has been likened to honey production. We draw parallels between bees and human industrial organisation as well as between the role and responsibilities of the bookkeeper and the beekeeper.

Zadaniem artykułu jest ukazanie dorobku piśmiennictwa pszczelniczego na Śląsku. Pretekstem do poruszenia tego tematu jest przypadająca w 2011 roku dwusetna rocznica urodzin wybitnego pszczelarza Jana Dzierżona. Osoba i dokonania najsłynniejszego chyba w świecie Ślązaka do tego stopnia zdominowały historię pszczelarstwa tego regionu, że właściwie bardzo niewiele mówi się o dorobku innych działających aktywnie śląskich pszczelarzach praktykach i publicystach. Tymczasem dorobek ten jest imponujący. W części pierwszej artykułu przypomniano Nickela Jacoba ze Szprotawy, autora pierwszej wydanej na Śląsku książki pszczelarskiej, uznanego jednocześnie za ojca niemieckiej bibliografii pszczelarskiej. Wśród pionierów niemieckiej literatury fachowej dotyczącej pszczół znajduje się też Johann Coler ze Złotoryi. W XVIII wieku swą działalność praktyczną i publicystyczną w znacznej mierze związali ze Śląskiem Łużyczanin Adam Gottlieb Schirach i Niemiec Johann Riem. W dziełach innych autorów z zakresu gospodarstwa wiejskiego pojawiają się również fragmenty poświęcone pszczelarstwu. Dorobek swych poprzedników wzbogacił i swą działalnością rozsławił śląskie pszczelarstwo ksiądz dr Jan Dzierżon, odkrywca partenogenezy, konstruktor nowoczesnego ula, autor licznych publikacji. „Księciu pszczół” poświęcona została druga część artykułu. Przedstawiono w niej pokrótce jego życie i działalność, dzieje walki o uznanie teorii partenogenezy, ogromny dorobek publicystyczny. Wskazano jednocześnie na brak opracowania pełnej bibliografii podmiotowej. Dzierżon był wydawcą jednego z pierwszych na Śląsku czasopism pszczelarskich. Dorobek śląskiego czasopiśmiennictwa pszczelarskiego jest bogaty i dziwi fakt, że właściwie w bardzo małym dotychczas stopniu został poznany. Część trzecią poświęcono niemieckim i polskim czasopismom pszczelarskim wydawanym na Śląsku. Uwzględniono tutaj tytuły samoistne oraz dodatki. W podsumowaniu wykazano, że we wszystkich obszarach bibliografia piśmiennictwa śląskiego wymaga kompleksowego rozpoznania. Stan opracowania piśmiennictwa pszczelarskiego na Śląsku stanowi w pewnej mierze odbicie stanu bibliografii tego zagadnienia na ziemiach polskich.

The economically most important honey bee species, Apis mellifera, was formerly considered to be parasitized by one microsporidian, Nosema apis. Recently, [Higes, M., Martin, R., Meana, A., 2006. Nosema ceranae, a new microsporidian parasite in honeybees in Europe, J. Invertebr. Pathol. 92, 93-95] and [Huang, W.-F., Jiang, J.-H., Chen, Y.-W., Wang, C.-H., 2007. A Nosema ceranae isolate from the honeybee Apis mellifera. Apidologie 38, 30-37] used 16S (SSU) rRNA gene sequences to demonstrate the presence of Nosema ceranae in A. mellifera from Spain and Taiwan, respectively. We developed a rapid method to differentiate between N. apis and N. ceranae based on PCR-RFLPs of partial SSU rRNA. The reliability of the method was confirmed by sequencing 29 isolates from across the world (N = 9 isolates gave N. apis RFLPs and sequences, N = 20 isolates gave N. ceranae RFLPs and sequences; 100%, correct classification). We then employed the method to analyze N = 115 isolates from across the world. Our data, combined with N = 36 additional published sequences demonstrate that (i) N. ceranae most likely jumped host to A. mellifera, probably within the last decade, (ii) that host colonies and individuals may be co-infected by both microsporidia species, and that (iii) N. ceranae is now a parasite of A. mellifera across most of the world. The rapid, long-distance dispersal of N. ceranae is likely due to transport of infected honey bees by commercial or hobbyist beekeepers. We discuss the implications of this emergent pathogen for worldwide beekeeping. (c) 2007 Elsevier Inc. All rights reserved.
