Terrestrial jumping in the mangrove killifish Kryptolebias marmoratus
Meeting Abstract 49.4 Saturday, Jan. 5 Terrestrial jumping in the mangrove killifish Kryptolebias marmoratus PACE, C.; GIBB, A.C.*; ECKEL, J.; Northern Arizona University; Northern Arizona University; Northern Arizona University alice.gibb@nau.edu The amphibious mangrove killifish (Kryptolebias marmoratus) exhibits terrestrial jumping (or leaping); however, the mechanism that generates this behavior is undescribed. We address two questions about this behavior: […]
Swimming spines of sharks
Meeting Abstract 49.5 Saturday, Jan. 5 Swimming spines of sharks PORTER, ME*; ROQUE, CM; SUMMERS, AP; University of California, Irvine; University of California, Irvine; University of California, Irvine porterm@uci.edu Maneuverability is a characteristic of locomotion that is difficult to assess, and can be measured as the turning radius of an animal, turning speed, the ability to accelerate […]
Kinetics of quadrupedal locomotion on slippery and rough arboreal trackways
Meeting Abstract 49.2 Saturday, Jan. 5 Kinetics of quadrupedal locomotion on slippery and rough arboreal trackways LAMMERS, A.R.; Cleveland State Univ., Ohio a.Lammers13@csuohio.edu Most small quadrupedal mammals regularly encounter and move on fallen tree branches, twigs and logs. Arboreal substrates have a wide range of textures, but all studies of locomotion on arboreal substrates attempt to provide […]
Independent Effects of Weight and Mass on Muscle Activity During Walking
Meeting Abstract 49.3 Saturday, Jan. 5 Independent Effects of Weight and Mass on Muscle Activity During Walking MCGOWAN, C.P.; University of Texas at Austin cpmcgowan@mail.utexas.edu Most studies agree that both gastrocnemius (GAS) and soleus (SOL) contribute to weight support during walking in humans. However, there is no current consensus as to the relative contribution of GAS and […]
Climbing on the floor Kinematics and energy cost of locomotion for horizontal and vertical crawling are not different
Meeting Abstract 49.1 Saturday, Jan. 5 Climbing on the floor: Kinematics and energy cost of locomotion for horizontal and vertical crawling are not different WOODS JR., W. A.*; VANGRIETHUIJSEN, L.; TRIMMER, B. A. ; Tufts University; Tufts University; Tufts University william.woods@tufts.edu Regardless of body orientation, caterpillars accomplish forward locomotion by lifting , swinging forward, and replacing successive […]
Single origin of a lake-wide pigmentation locus in the rock-dwelling cichlids of Lake Malawi
Meeting Abstract 49.1 Monday, Jan. 5 Single origin of a lake-wide pigmentation locus in the rock-dwelling cichlids of Lake Malawi. ROBERTS, Reade B.*; KOCHER, Thomas D.; University of Maryland, College Park reade@umd.edu The phenotypic diversity present in the cichlid fishes of Lake Malawi is amazingly rich given the relatively short history in which it has evolved. Perhaps […]

Meeting Abstract 49.2 Monday, Jan. 5 Rapid visual system evolution within the cichlid species flock of Lake Malawi O’QUIN, Kelly E.*; MARSHALL, Justin; CRONIN, Thomas; CARLETON, Karen L.; Univ. of Maryland, College Park; Univ. of Queensland; Univ. of Maryland Baltimore County; Univ. of Maryland, College Park koquin@umd.edu Members of the cichlid species flock of Lake Malawi have […]
MicroRNAs from cichlid genomes
Meeting Abstract 49.5 Monday, Jan. 5 MicroRNAs from cichlid genomes LOH, Y.-H.E.**; STREELMAN, J.T.; Georgia Institute of Technology; Georgia Institute of Technology yloh3@gatech.edu MicroRNAs are small RNA molecules of approximately 22 nucleotides known to hybridize to 3′ untranslated regions (3′ UTRs) of target messenger RNAs (mRNAs), thereby effecting gene silencing through translation inhibition or targeted mRNA degradation. […]
In search of evolutionary origin of cichlids among percomorph fishes
Meeting Abstract 49.6 Monday, Jan. 5 In search of evolutionary origin of cichlids among percomorph fishes CHEN, Wei-Jen*; MAYDEN, Richard L.; Saint Louis University wjchen.actinops@gmail.com The family Cichlidae is one of the most diverse clades of freshwater fishes. Species from this group are a major component of the modern ichthyofauna in their native freshwater habitats, and constitute […]
