Optimal Body Size With Respect To Maximal Speed For The Yellow-Spotted Monitor Lizard (Varanus Panoptes; Varanidae), Christofer J. Clemente, Philip C. Withers, Graham Thompson Jan 2012

Optimal Body Size With Respect To Maximal Speed For The Yellow-Spotted Monitor Lizard (Varanus Panoptes; Varanidae), Christofer J. Clemente, Philip C. Withers, Graham Thompson

Research outputs 2012

Studies of locomotor performance often link variation in morphology with ecology. While maximum sprint speed is a commonly used performance variable, the absolute limits for this performance trait are not completely understood. Absolute maximal speed has often been shown to increase linearly with body size, but several comparative studies covering a large range of body sizes suggest that maximal speed does not increase indefinitely with body mass but rather reaches an optimum after which speed declines. Because of the comparative nature of these studies, it is difficult to determine whether this decrease is due to biomechanical constraints on maximal speed …

Fussy Feeders: Phyllosoma Larvae Of The Western Rocklobster (Panulirus Cygnus) Demonstrate Prey Preference, M I Saunders, P A Thompson, A G Jeffs, Christin Sawstrom, N Sachlikidis, L E Beckley, A M Waite Jan 2012

Fussy Feeders: Phyllosoma Larvae Of The Western Rocklobster (Panulirus Cygnus) Demonstrate Prey Preference, M I Saunders, P A Thompson, A G Jeffs, Christin Sawstrom, N Sachlikidis, L E Beckley, A M Waite

Research outputs 2012

The Western Rocklobster (Panulirus cygnus) is the most valuable single species fishery in Australia and the largest single country spiny lobster fishery in the world. In recent years a well-known relationship between oceanographic conditions and lobster recruitment has become uncoupled, with significantly lower recruitment than expected, generating interest in the factors influencing survival and development of the planktonic larval stages. The nutritional requirements and wild prey of the planktotrophic larval stage (phyllosoma) of P. cygnus were previously unknown, hampering both management and aquaculture efforts for this species. Ship-board feeding trials of wild-caught mid-late stage P. cygnus phyllosoma in the eastern …

Human DiGeorge Critical Region 8 (DGCR8) is an essential microRNA (miRNA) processing factor that is activated via direct interaction with Fe(III) heme. In order for DGCR8 to bind heme, it must dimerize using a dimerization domain embedded within its heme-binding domain (HBD). We previously reported a crystal structure of the dimerization domain from human DGCR8, which demonstrated how dimerization results in the formation of a surface important for association with heme. Here, in an attempt to crystallize the HBD, we search for DGCR8 homologues and show that DGCR8 from Patiria miniata (bat star) also binds heme. The extinction coefficients (ε) …
