Life history can help dictate resilience in the face of decline, and therefore understanding attributes such as sexual size dimorphism, site fidelity, and survival rates are essential. Australia is well-known for its diversity of scincid lizards, but we have little detailed knowledge of the life histories of individual scincid species. To examine the life history of the Coppertail Skink (Ctenotus taeniolatus), which uses scattered surface rocks as shelter, we estimated survival rates, growth rates, and age at maturity during a three-year capture-mark- recapture study. We captured mostly females (> 84%), and of individuals captured more than once, we captured 54.3% at least twice beneath the same rock, and of those, 64% were always beneath the same rock (up to five captures).

Three new species of Ctenotus (Reptilia: Sauria: Scincidae) from the Kimberley region of Western Australia, with comments on the status of Ctenotus decaneurus yampiensis Paul Horner Museum and Art Gallery of the Northern Territory, GPO Box 4646, Darwin, Northern Territory 0801, Australia. E-mail: [email protected] Abstract – Three new species of Ctenotus Storr, 1964 (Reptilia: Sauria: Scinci- dae), C. halysis sp. nov., C. mesotes sp. nov. and C. vagus sp. nov. are described. Previously confused with C. decaneurus Storr, 1970 or C. alacer Storr, 1970, C. halysis sp. nov. and C. vagus sp. nov. are members of the C. atlas species com- plex. Ctenotus mesotes sp. nov. was previously confused with C. tantillus Storr, 1975 and is a member of the C. schomburgkii species complex. The new taxa are terrestrial, occurring in woodland habitats on sandy soils in the Kimberley region of Western Australia and are distinguished from congeners by combi- nations of body patterns, mensural and meristic characteristics. Comments are provided on the taxonomic status of C. yampiensis Storr, 1975 which is considered, as in the original description, a subspecies of C. decaneurus. Re- descriptions of C. d. decaneurus and C. d. yampiensis are provided. Keywords – Ctenotus alacer, decaneurus, yampiensis, halysis, mesotes, tantillus, vagus, morphology, new species, Kimberley region, Western Australia INTRODUCTION by combinations of size, scale characteristics, body Ctenotus Storr, 1964 is the most species-rich genus colour and patterns. of scincid lizards in Australia, with almost 100 taxa recognised (Horner 2007; Wilson and Swan 2008).

  • Characterization of Arm Autotomy in the Octopus, Abdopus Aculeatus (D’Orbigny, 1834)
    Characterization of Arm Autotomy in the Octopus, Abdopus aculeatus (d’Orbigny, 1834) By Jean Sagman Alupay A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Integrative Biology in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Roy L. Caldwell, Chair Professor David Lindberg Professor Damian Elias Fall 2013 ABSTRACT Characterization of Arm Autotomy in the Octopus, Abdopus aculeatus (d’Orbigny, 1834) By Jean Sagman Alupay Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Roy L. Caldwell, Chair Autotomy is the shedding of a body part as a means of secondary defense against a predator that has already made contact with the organism. This defense mechanism has been widely studied in a few model taxa, specifically lizards, a few groups of arthropods, and some echinoderms. All of these model organisms have a hard endo- or exo-skeleton surrounding the autotomized body part. There are several animals that are capable of autotomizing a limb but do not exhibit the same biological trends that these model organisms have in common. As a result, the mechanisms that underlie autotomy in the hard-bodied animals may not apply for soft bodied organisms. A behavioral ecology approach was used to study arm autotomy in the octopus, Abdopus aculeatus. Investigations concentrated on understanding the mechanistic underpinnings and adaptive value of autotomy in this soft-bodied animal. A. aculeatus was observed in the field on Mactan Island, Philippines in the dry and wet seasons, and compared with populations previously studied in Indonesia.

    1 THE AUSTRALIAN SOCIETY OF HERPETOLOGISTS INCORPORATED NEWSLETTER 48 Published 29 October 2014 2 Letter from the editor This letter finds itself far removed from last year’s ASH conference, held in Point Wolstoncroft, New South Wales. Run by Frank Lemckert and Michael Mahony and their team of froglab strong, the conference featured some new additions including the hospitality suite (as inspired by the Turtle Survival Alliance conference in Tuscon, Arizona though sadly lacking of the naked basketball), egg and goon race and bouncing castle (Simon’s was a deprived childhood), as well as the more traditional elements of ASH such as the cricket match and Glenn Shea’s trivia quiz. May I just add that Glenn Shea wowed everyone with his delightful skin tight, anatomically correct, and multi-coloured, leggings! To the joy of everybody in the world, the conference was opened by our very own Hal Cogger (I love you Hal). Plenary speeches were given by Dale Roberts, Lin Schwarzkopf and Gordon Grigg and concurrent sessions were run about all that is cutting edge in science and herpetology. Of note, award winning speeches were given by Kate Hodges (Ph.D) and Grant Webster (Honours) and the poster prize was awarded to Claire Treilibs. Thank you to everyone who contributed towards an update and Jacquie Herbert for all the fantastic photos. By now I trust you are all preparing for the fast approaching ASH 2014, the 50 year reunion and set to have many treats in store. I am sad to not be able to join you all in celebrating what is sure to be, an informative and fun spectacle.
