The Hot-Blooded Insects: Strategies and Mechanisms of Thermoregulation

TLDR
The Hot-Blooded Insects takes a giant step forward by presenting an overview of what is now known about thermoregulation in all of the major insect groups, offering new insights on physiology, ecology, and evolution.

"Majoring" and "Minoring" by Foraging Bumblebees, Bombus Vagans: An Experimental Analysis

TLDR
It is concluded that the most important problem faced by the foraging bees attempting to enhance food intake is that of assessing the resources, which often change rapidly.

Do Bumblebees Forage Optimally, and Does It Matter?

Foraging behavior of bumblebees has been in the past analyzed from two major perspectives. On the one hand, behavioral mechanisms have been studied to learn more about the animal. On the other…

AN EXPERIMENTAL INVESTIGATION OF INSIGHT IN COMMON RAVENS (CORVUS CORAX)

I presented four groups of Common Ravens (Corvus corax) with a problem that they had never encountered before. Could they demonstrate the solution to this problem without first practicing or learning…

Winter foraging at carcasses by three sympatric corvids, with emphasis on recruitment by the raven, Corvus corax

    Behavioral Ecology and Sociobiology
  • 1 September 1988
TLDR
It is concluded that the feeding crowds of ravens consist primarily of juvenile non-breeding vagrants who (unlike some resident adults) roost communally and who vigorously recruit each other in part to neutralize the aggressiveness of resident adults defending prized food bonanzas.

Resource heterogeneity and patterns of movement in foraging bumblebees

TLDR
The systematic foraging behavior of B. vagans workers foraging from Aconitum napellus inflorescences may be a mechanism of reducing the revisiting of just-emptied flowers.

The Energetics of Pollination

TLDR
There is a mutual interdependence involving a set of evolved "games" where the pollinators try to get the most for their foraging effort, while flowers provide the least reward possible.
