Development in the invasive colonial ascidian Didemnum vexillum
Meeting Abstract 128.5 Tuesday, Jan. 7 14:30 Development in the invasive colonial ascidian Didemnum vexillum IRVINE, SQ*; STEPHENS, CE; Unv. of Rhode Island; Unv. of Rhode Island steven.irvine@uri.edu D. vexillum is an encrusting invasive colonial tunicate. It shares a peculiar form of asexual development, called pyloric budding, with other didemnid ascidians. In pyloric budding two buds form […]
Development and life cycle evolution in the sea nettle jellies (Pelagiidae)
Meeting Abstract 128.2 Tuesday, Jan. 7 13:45 Development and life cycle evolution in the sea nettle jellies (Pelagiidae) HELM, RR*; DUNN, CW; Brown University rebecca.rae.helm@gmail.com Life cycle evolution is difficult to study because many instances of life cycle transition occur at the base of diverse lineages. One exception is the mauve stinger jelly Pelagia noctiluca, which has […]
The maintenance of risky personalities in yellow-bellied marmots
Meeting Abstract 127.7 Tuesday, Jan. 7 15:00 The maintenance of risky personalities in yellow-bellied marmots PETELLE, M/B*; BLUMSTEIN, D/T; Univ. of California, Los Angeles mpetelle@ucla.edu Animals vary in the risks they take and this may be a personality trait. There are three hypotheses for the maintenance of risky personality traits. First, the residual reproductive value hypothesis uses […]

Exploration of the Behaviors Defining Personality in African Elephants
Meeting Abstract 127.4 Tuesday, Jan. 7 14:15 Exploration of the Behaviors Defining Personality in African Elephants FELTON, S.K.*; MERTE, C.E.; SCHULTE, B.A.; Western Kentucky University, Bowling Green; Georgia Southern University, Statesboro; Western Kentucky University, Bowling Green shilo.felton749@topper.wku.edu In sub-Saharan Africa, crop-raiding by African elephants is a major component of human-elephant conflict (HEC) which impedes conservation efforts. Understanding […]
Does the development of cerebral lateralization play a role in the evolution of personality
Meeting Abstract 127.1 Tuesday, Jan. 7 13:30 Does the development of cerebral lateralization play a role in the evolution of personality? HURD, PL; University of Alberta phurd@ualberta.ca Cerebral lateralization, the disproportionate partitioning of tasks to one cerebral hemisphere or the other, appears to be ubiquitous among vertebrate species. Empirical work on non-human animals demonstrates some selective advantages […]
Developmental exposure to corticosterone and adult challenge with endotoxin have interactive effects on behavior in zebra finches (Taeniopygia guttata)
Meeting Abstract 127.2 Tuesday, Jan. 7 13:45 Developmental exposure to corticosterone and adult challenge with endotoxin have interactive effects on behavior in zebra finches (Taeniopygia guttata) GRINDSTAFF, JL*; WASELIK, M; Oklahoma State University, Stillwater; Oklahoma State University, Stillwater jen.grindstaff@okstate.edu Exposure to parasites, immune challenges, and other stressors during development has the potential to alter personality expression in […]
Behavioral type – environment correlations in three-spined stickleback
Meeting Abstract 127.6 Tuesday, Jan. 7 14:45 Behavioral type – environment correlations in three-spined stickleback PEARISH, S.*; BELL, A.M.; Univ. of Illinois, Urbana; Univ. of Illinois, Urbana pearish1@illinois.edu There is growing evidence for consistent individual differences in behavior. It is likely that different behavioral types of individuals within populations are nonrandomly distributed in the environment, creating behavioral […]
