When approaching a landing surface, many flying animals use visual feedback to control their landing. Here, we studied how foraging bumblebees (Bombus…

High-resolution numerical simulations of a tethered model bumblebee in forward flight are performed superimposing homogeneous isotropic turbulent fluctuations to the uniform inflow. Despite tremendous variation in turbulence intensity, between 17% and 99% with respect to the mean flow, we do ...

Download scientific diagram | Queen bumblebees (Bombus terrestris) that have recently emerged from artificial or natural hibernation spend more time resting than flying. (a) Aerial view of field site where harmonic radar tracking took place (an orthomosaic created from drone photography; flight ...

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 ...

The movement of organisms is subject to a multitude of influences of widely varying character: from the bio-mechanics of the individual, over the interaction with the complex environment many animals live in, to evolutionary pressure and energy constraints. As the number of factors is large, ...

January 1, 2010 - PDF | It has been known for a century that quasisteady attached flows are insufficient to explain aerodynamic force production in bumblebees and many... | Find, read and cite all the research you need on ResearchGate

We consider the metric-affine formulation of bumblebee gravity, derive the field equations, and show that the connection can be written as Levi-Civita of a disformally related metric in which the bumblebee field determines the disformal part. As a consequence, the bumblebee field gets coupled ...

Background Accurate estimates of movement behavior and distances travelled by animals are difficult to obtain, especially for small-bodied insects where transmitter weights have prevented the use of radio-tracking. Methodology/Principal Findings Here, we report the first successful use of micro ...

Animals that move through complex habitats must frequently contend with obstacles in their path. Humans and other highly cognitive vertebrates avoi...

March 2, 2012 - (PhysOrg.com) -- Bumblebees use complex flying patterns to avoid predators according to new research from Queen Mary, University of London.

By combining functional, ecological and evolutionary perspectives, neuroecology can provide key insights into understanding how behaviour and the unde…

Flying bees make extensive use of optic flow: the apparent motion in the visual scene generated by their own movement. Much of what is known about bees' visually-guided flight comes from experiments employing real physical objects, which constrains the ...

AERODYNAMIC theories predict that the mechanical power required for flapping animal flight varies with flight speed according to a 'U-shaped' curve1–6. At some intermediate speed there is a pronounced power minimum, typically half the power required for hovering flight.

Fortunately, the bumblebees never heard this bit of news and so went on flying as usual. ... Insects (1968, 1972), 68.

Answer (1 of 23): I’ll interpret “defy physics” as “unexplained by current physics” to avoid arguments in other answers. I’ll quote the Wikipedia article at length since it has both the origin and the resolution of the “bumblebee problem”: > In Antoine Magnan's 1934 book Le ...

Bees, of course, with secrets of their own, turn these impossibilities to trivialities. In recent years, however, with our current physical knowledge and computational advancements, these secrets have been unraveled, and we can now decisively pinpoint the physics of the flight of the bumblebee.
