Sibling Rivalry: A Comparison Of Giant Panda (Ailuropoda Melanoleuca) Twin Behavior, Taryn Chudo Jan 2018

Sibling Rivalry: A Comparison Of Giant Panda (Ailuropoda Melanoleuca) Twin Behavior, Taryn Chudo

Undergraduate Honors Thesis Projects

Expanded knowledge on an animal’s individual behavior would be useful in reintroduction programs for endangered species around the globe. Currently, reintroduction program criteria focus primarily on physical characteristics such as age, sex, and overall health for the selection of candidates. However, behavioral deficiencies have been found in captive populations, producing adverse effects on reintroduction program success. The giant panda (Ailuropoda melanoleuca) is a species that would benefit from understanding the impact of behavior on reintroduction success. This study focused on the relationship of behavior with kinship, birth weight and age. No significant correlation was found between birth weight …

Characterizing Curiosity-Related Behavior In Bottlenose (Tursiops Truncatus) And Roughtoothed (Steno Bredanensis) Dolphins, Malin Lilley, Amber J. De Vere, Deirdre Yeater, Stan A. Kuczaj Ii

Psychology Faculty Publications

Dolphins are frequently described as curious animals; however, there have been few systematic investigations of how dolphins behave when they are curious and the extent to which individual differences in curiosity exist in dolphins. Previous research has described individual differences in dolphins’ frequency of interactions with environmental enrichment as well as quantifying curiosity-related traits of dolphins via personality assessments, though behavioral observation and trait rating components have not been part of the same study. The present study describes two different experiments designed to elicit curiosity in 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis) dolphins. …

Foraging Habitat Of Pileated Woodpeckers In Relation To A Managed Landscape On The Hoopa Valley Reservation, Northwestern California, Dawn Michelle Blake Jan 2018

Foraging Habitat Of Pileated Woodpeckers In Relation To A Managed Landscape On The Hoopa Valley Reservation, Northwestern California, Dawn Michelle Blake

Cal Poly Humboldt theses and projects

The Pileated woodpecker (Dryocopus pileatus) is associated with older forest stages—larger diameter trees and snags for roosting, nesting and foraging, but they also use managed forests. The Hoopa Reservation is approximately 37,000 ha of mostly forested area with an array of seral stages. The Hoopa Tribe manages timber, and explicitly provides habitat for woodpeckers according to the Tribe’s Forest Management Plan (FMP). No formal study has assessed woodpecker habitat at Hoopa, and habitat has not been well described in this region. I captured eleven woodpeckers and outfitted them with transmitters between 2009 and 2014, and I used resource …

Investigations On The Cannibalistic Behavior Of Ladybird Beetlecoccinella Septempunctata L. (Coleoptera: Coccinellidae) Under Laboratory Conditions, Muhammad Hamayoon Khan, Zeynep Yoldaş

Turkish Journal of Zoology

Cannibalism or intraspecific predation, where one species feeds on individuals of its own species, is a widespread phenomenon in most aphidophagous coccinellids. Laboratory studies were conducted on the cannibalistic behavior of various developmental stages of Coccinella septempunctata L. (Coleoptera: Coccinellidae) in the presence and absence of natural food, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae). In both the presence and absence of aphids, the eggs and 1st and 2nd instars of C. septempunctata were cannibalized by the adults, and the level was inversely related to the availability of aphids. The same was also true for cannibalism of eggs by larvae and within …

Habitat Structure And Host Plant Specialization Drive Taxonomic Andfunctional Composition Of Heteroptera In Postfire Successional Habitats, Eduardo Mateos, Marta Goula, Teresa Sauras, Xavier Santos Jan 2018

Habitat Structure And Host Plant Specialization Drive Taxonomic Andfunctional Composition Of Heteroptera In Postfire Successional Habitats, Eduardo Mateos, Marta Goula, Teresa Sauras, Xavier Santos

Turkish Journal of Zoology

Changes in habitat structure are the main driving forces for responses of animal assemblages to fire. According to the disturbance theory, generalist species are expected to outperform specialists in variable environments. Thus, we hypothesized that omnivorous and polyphagous species will become more abundant in unstable postfire successional vegetation, whereas monophagous (specialists), due to their strong dependence on host plants, are expected to respond according to the responses of plant hosts. We compared the responses of true bug (Heteroptera) assemblages in stable (unburnt) versus unstable (postfire successional) environments as this group shows a high diversity of feeding strategies. Redundancy analysis fitted …
