Preferred viewing directions of bumblebees (Bombus terrestris L.) when learning and approaching their nest site.
Many bees and wasps learn about the immediate surroundings of their nest during learning flights, in which they look back towards the nest and acquire visual information that guides their subsequent returns. Visual guidance to the nest is simplified by the insects' tendency to adopt similar viewing directions during learning and return flights. To understand better the factors determining the p...
متن کاملSpatio-temporal dynamics of bumblebee nest parasites (Bombus subgenus Psythirus ssp.) and their hosts (Bombus spp.).
1. A 39-year bumblebee data base was used to study the codistribution of six cuckoo bumblebees in the subgenus Psythirus of Bombus (hereafter called Psythirus) and their free-living bumblebee hosts in the British Isles. 2. A model of nest parasitism predicted host threshold densities and stable deterministic dynamics, with fluctuations only emerging as a result of environmental or demographic s...
متن کاملNest wax triggers worker reproduction in the bumblebee Bombus terrestris.
Social insects are well known for their high level of cooperation. Workers of the primitively eusocial bumblebee Bombus terrestris are able to produce male offspring in the presence of a queen. Nonetheless, they only compete for reproduction, in the so-called competition phase, when the workforce is large enough to support the rearing of reproductives. So far, little is known about the proximat...
متن کاملEin semantisches Netz des Informationsmanagements im Krankenhaus
Die Literatur zum Informationsmanagement ist durch eine Vielzahl unterschiedlicher theoretischer Ansätze und praxisorientierter Frameworks geprägt. Zusammenhänge zwischen Aspekten des strategischen Informationsmanagements, der IT Governance, des IT Service Managements und dem Informationssystems sind nicht ausreichend formalisiert, um auf deren Grundlage entscheidungsunterstützende Werkzeuge fü...
متن کاملAn interspecific comparison of foraging range and nest density of four bumblebee (Bombus) species.
Bumblebees are major pollinators of crops and wildflowers in northern temperate regions. Knowledge of their ecology is vital for the design of effective management and conservation strategies but key aspects remain poorly understood. Here we employed microsatellite markers to estimate and compare foraging range and nest density among four UK species: Bombus terrestris, Bombus pascuorum, Bombus ...
