In the broadest sense, I am interested in how animals use information
from their environments in making decisions that affect their fitness, especially reproduction and foraging. Although
my most recent work has been in animal behavior, I plan to work in future in the overlap area between physiological
ecology and behavioral ecology, primarily with, but not restricted to, insects. In other words, I am interested
in both proximate and ultimate questions in animal ecology and how these can be integrated in the study of mating
systems, female choice, foraging, etc.
My research focus has recently been on the prairie mole cricket, Gryllotalpa major, a rare (and probably threatened)
burrowing grasslands insect. Since the species is rare and little known, I have a strong commitment to providing
details that will promote its conservation. Although I am not a conservation biologist in the strictest sense,
I intend that my work always include a conservation aspect. Projects asking questions about G. major's mating system
(see Hill 1999), communication through vibration (see Hill and Shadley 1997), and environmental and social effects
on calling effort (see Hill 1998) have provided me with just enough answers to be able to ask questions in a dozen
directions. Males construct "acoustic" burrows in the moist prairie soils in the spring of the year and
produce a calling song to attract females for mating. These calls can be heard by people up to 400 meters away
from the burrow and are currently our only reliable source of locating or identifying the species. I have spent
most of my field time studying male communication, and I am fairly certain that most of my "sampling"
of this species in future will involve acoustics, as it has in the past.
My other major research line is in collaboration with Dr. Harrington Wells, studying honeybee foraging ecology.
My primary interest is in how honeybees use color cues in making foraging choices and how some of these color cues
elicit constancy from individuals. Honeybees have good, trichromatic color vision, similar to our own, and can
easily discriminate among colors in their visible spectrum (UV to possibly near red). I want to know more about
the color constraints under which honeybees operate as they forage on a patch of natural or artificial flowers.
The following research projects are currently under way in our lab:
- Long-term monitoring project of the White Oak Prairie population of the
prairie mole cricket, Gryllotalpa major
- Airborne communication in G. major
- Vibration as a communication channel
- Sound fields and male spacing patterns: making oneself heard as an individual
- Male and female wing morphology in the Gryllotalpidae: evidence from SEM
- Phylogeny of the family Gryllotalpidae (Insecta: Orthoptera): morphological
and DNA sequencing support
- Individual identification based on analysis of the calling song in G.
- Testing hypotheses of lek formation in G. major: the hotshot model
- Harmonic content of the calling song and mating success in G. major
- How G. major perceives its environment
- Passive attraction vs active female choice in systems where display is
- Honeybee constancy to color when foraging distance varies
- Honeybee constancy to color when handling time varies
- Honeybee constancy to color when predation pressure varies
- Bumblebee foraging behavior on an artificial flower patches
