FINKLER, M.S*; GILLEM, A.D.; Indiana Univ. Kokomo: A comparison of stored energy reserves before and after oviposition in female Ambystoma texanum and sympatric Ambystoma jeffersonianum-laterale complex gynogenics We examined interspecific differences in the storage lipid and glycogen contents of female Ambystoma texanum (a bisexual species) and gynogenic hybrid females from the Ambystoma jeffersonianum-laterale complex found […]

A Molt-Inhibiting Hormone (MIH)-like Factor in Secondary Limb Buds that Lowers Hemolymph Ecdysteroid Levels in the Land Crab Gecarcinus lateralis
LEE, Kara J.*; YU, Xiaoli; CHANG, Ernest S.; MYKLES, Donald L.; Colorado State University, Ft. Collins; Colorado State University, Ft. Collins; Bodega Marine Lab, Bodega Bay, CA; Colorado State University, Ft. Collins: A Molt-Inhibiting Hormone (MIH)-like Factor in Secondary Limb Buds that Lowers Hemolymph Ecdysteroid Levels in the Land Crab Gecarcinus lateralis. Molting in crustaceans […]
effects of salinity on physiological and molecular responses in extremophilic green algae
PRITCHARD, Justin/R; BOETTCHER, Anne; MAJOR, Kelly; University of California Los Angeles and University of South Alabama; University of South Alabama; University of South Alabama: effects of salinity on physiological and molecular responses in extremophilic green algae Members of the green algal genus, Dunaliella, exhibit broad environmental tolerance. To investigate the effects of salinity on physiological […]
Whole-animal Closed-loop Locomotor Performance of Weakly Electric Gymnotiform Fishes
TAN, EW; COWAN, NJ; FORTUNE, ES; Johns Hopkins Univ.: Whole-animal Closed-loop Locomotor Performance of Weakly Electric Gymnotiform Fishes Eigenmannia and Sternopygus actively maintain their positions within refuges and will track the motion of salient objects in their environment during daylight. We developed a mechanism to assess the closed-loop, whole-animal sensorimotor performance in these and other […]
Wake structure of a swimming roach (rutilus rutilus) as a function of speedtailbeat frequency
MASTERS, J.C.*; MINETTI, A.; Manchester Metropolitan University, United Kingdom; Manchester Metropolitan University, United Kingdom: Wake structure of a swimming roach (rutilus rutilus) as a function of speed/tailbeat frequency The social and behavioural benefits of schooling in fish have been investigated in depth in the past; however, very little research has focused on the hydrodynamic benefits […]
Variation in male signaling and female preference in Photinus greeni fireflies
MICHAELIDIS, C.I.; DEMARY, K.; LEWIS, S.M.; Swarthmore College, Pennsylvania; Tufts University, Medford, Massachusetts; Tufts University, Medford, Massachusetts: Variation in male signaling and female preference in Photinus greeni fireflies In Photinus fireflies, flying males emit bioluminescent advertisement flashes to which conspecific females selectively respond. Previous work has examined variation in male signals and female preferences in […]
Understanding the interplay between the tephritid olive fly and its bacterial symbionts
ESTES, AM; PIERSON, EA; University of Arizona, Dept. of Ecology and Evolutionary Biology; 2University of Arizona, Dept. of Plant Pathology and Microbiology: Understanding the interplay between the tephritid olive fly and its bacterial symbionts. Symbiosis, the physiologically intimate interaction between two genetically distinct organisms, encompasses relationships from parasitic to mutualistic and facultative to obligate. Obligately […]
The site of yolk protein synthesis in the green crab
NOVOTNEY, D.A.*; DING, X.; LAHEY, B.C.; LOVETT, D.L.; BORST, D.W.; Illinois State University, Normal; Illinois State University, Normal; Illinois State University, Normal; The College of New Jersey, Ewing; Illinois State University, Normal: The site of yolk protein synthesis in the green crab Most crustacean eggs contain large amounts of yolk protein. However, in most species […]
The role and characterization of corticosteroid-binding globulin in southern toads exposed to coal fly ash
WARD, Chelsea K. *; FONTES, Cris; MENDONCA, Mary T.; Auburn University; Auburn Univerisity; Auburn University: The role and characterization of corticosteroid-binding globulin in southern toads exposed to coal fly ash Corticosteroid-binding globulin (CBG) is a protein that binds corticosterone (B) and is thought to render the steroid biologically inactive. During chronic stress, CBG may modulate […]
The neural basis of motivation for natural and drug rewards
RHODES, Justin/S; CRABBE, John/C; Oregon Health & Science Univ: The neural basis of motivation for natural and drug rewards Motivation controls voluntary behavior up to the limit of physical capacity. Thus, it probably accounts for a large proportion of variation in behavior among individuals and species. Drugs of abuse can elicit powerful shifts in motivation […]
