The Effects Of Floral And Social Information On Bumblebee Forager Learning And Memory, Avery Hume Baker
The Effects Of Floral And Social Information On Bumblebee Forager Learning And Memory, Avery Hume Baker
Theses
Bumblebees rely on information gathered from their environment to make the best choices they can when foraging for pollen and nectar. The type of information gathered should influence how a bee learns and remembers it, but other factors such as the size of the bee’s brain may also play a role in the learning and remembering process. While social information learned from other organisms and information gathered directly from flowers can each be used alone to improve both the efficiency with which a bee learns to forage from a flower and how accurately and how long the bee remembers these …
Movement Patterns Of The Shovelnose Guitarfish (Pseudobatos Productus) And California Bat Ray (Myliobatis Californica) In The Southern California Bight, Annabel Gong
Theses
While the movement patterns of large elasmobranch species have been studied extensively, those of smaller, mesopredatory species remain understudied. The shovelnose guitarfish (Pseudobatos productus) and the California bat ray (Myliobatis californica) are among the least studied elasmobranchs in the Southern California Bight. This study quantified the broad- and fine-scale movement patterns of these species using passive acoustic telemetry. Twelve guitarfish were surgically implanted with coded acoustic transmitters at a known aggregation site off La Jolla (San Diego County), California, USA and tracked for 849.5 days each, on average. Six bat rays were also implanted here and tracked for …
Behavioral Choices Of Apple Snails, Pomacea Maculata, Under Varied Chemical Landscapes, Andrea Adams
Behavioral Choices Of Apple Snails, Pomacea Maculata, Under Varied Chemical Landscapes, Andrea Adams
Theses
Habitat choice is a critical behavior for organisms to successfully survive and reproduce. These choices are dictated by available environmental information about potential predation risks or food patches that form the organism’s sensory landscape. This study specifically focused on the behavioral choices of two invasive apple snail (Pomacea maculata) populations exposed to varying predation threats. We collected snails from Florida and Alabama which were used in laboratory experiments with varied sensory landscapes. Trials consisted of controls with no cues (FL: n = 7, AL: n= 7), an attractive treatment with introduced food cues (FL: n = 4, AL: …
