Congratulations to Erin Macartney and Angela Crean on their highly-acclaimed presentations at ISBE2014 in New York City.

 

Margo Adler's paper on dietary restriction and ageing in BioEssays has been featured on UNSW News, ABC News, ScienceDaily, Medical News Today, Scientific American, and many other media.

 

Thanks to Margo for the wonderful tie, which features spines on a beetle penis (dissected by Luis Cayetano). Finally, Russell owns a tie and can look respectable at special occasions.

30/10/2013: We celebrated the (near-) completion of Honours projects at our lab picnic above Coogee beach. It was a very hard day.

 

2/10/2013:  Most of the lab attended the Australasian Evolution Society meeting in Geelong, Vic. Nathan, Angela, Lára, Erin, Oscar and Aidan all gave excellent talks. We also encountered some of the local wildlife. Congratulations to Nathan on being chosen as runner-up for the Best Student Talk award!

Some current research projects

 

 

● Dietary ecology and developmental plasticity

We are broadly interested in how the environment (particularly the larval nutritional environment) shapes development, and the role that such effects play in evolution.

We have found that, in the Australian neriid fly Telostylinus angusticollis, sexual dimorphism in body size and shape is largely determined by larval nutrition (link). In a study by Alex Sentinella and DECRA research fellow Angela Crean, we have recently shown that the exaggeration of the male head and antenna (which are used as weapons and signals in sexual competition) depends on the amount of dietary protein available to larvae (link).

Research led by Margo Adler has shown that both larval and adult nutrition (link) as well as the social environment (link) also affect life history traits such as lifespan and ageing.

Elizabeth Cassidy has investigated the diversification of reaction norms for body shape in the Australian neriid flies (Telostylinus angusticollis and T. lineolatus). Her work has revealed interesting differences between the sexes in the patterns of morphological diversification.

Research by Erin Macartney and Angela Crean is extending this work to the effects of larval diet on sperm traits and reproductive ageing in males.

● The ecology of nongenetic inheritance

We have discovered that some environmental effects are transmitted across generations in T. angusticollis, resulting in an inheritance of acquired traits (link). Most intriguingly, we have found that a male's larval diet affects the body size of his offspring -- a pattern of nongenetic inheritance with interesting implications for sexual coevolution (link). Margo Adler's work has shown that such effects can depend on the parental social environment (link). Aidan Runagall-McNaull is currently applying the powerful "nutritional geometry" framework to investigate such effects.

Angela Crean is also exploring the potential for such effects to mediate telegony -- the transmission of a male's traits to the offspring of another male that mates with the same female.

Postdoctoral research fellow Lára Hallsson and student Oscar Lee are using the cosmopolitan bruchid beetle Callosobruchus maculatus to investigate nongenetic inheritance of body size and life history. We have found that both maternal and paternal nongenetic effects influence body size in this species but, intriguingly, such effects can act in opposite ways on male and female offspring (link).

In collaboration with Troy Day (Queen's University), we are developing theory on the potential for nongenetic inheritance to influence adaptation (link) and sexual coevolution  (link).

● Sexual conflict and the evolution of facultative sex

Nathan Burke is exploring the potential for sexual conflict to maintain an unusual  mode of reproduction in the Australian Giant Spiny Leaf Insect Extatosoma tiaratum. Females of this species can reproduce asexually (producing all-female broods), or mate and produce offspring of both sexes. Does sexual conflict contribute to the maintenance of this remarkable reproductive flexibility?

● Diet and fitness in wild antler flies

In collaboration with Howard Rundle (University of Ottawa) and postdoc Brian Mautz, we are investigating the effects of diet on male performance in wild antler flies -- a tiny Canadian piophilid fly that breeds exclusively on discarded antlers of moose and deer. Although antler flies are only 2 mm long, their remarkable site fidelity males it possible to mark flies with individual codes, observe them throughout their lives in the wild, and construct individual biographies for them. This species has provided the first evidence of ageing in wild insects (link), and has revealed that ageing can affect sexual selection (link).

● The genetic and environmental basis of condition

In collaboration with Howard Rundle (University of Ottawa) and postdocs Devin Arbuthnott and Martin Mallet, we are investigating the nature of condition dependence. We are using a powerful experimental design to unravel the relation between the genetic basis of condition (which is the focus of much theory) and the environmental effects on condition that are the focus of most empirical research. This work is being carried out on Drosophila melanogaster.
