A tale of paintbrushes, party drugs, cannibalism and obesity   View Summary
23 January 2013

Join us for this special lecture by Professor Stephen Simpson as part of the 50th birthday celebrations for the School of Biological Sciences.

Professor Stephen Simpson will talk about the link between locusts and human obesity
Professor Stephen Simpson will talk about the link between locusts and human obesity

Locust plagues are one of the most infamous insect scourges, affecting the lives of one in 10 people on the planet. But they have also provided important new clues into the causes of human obesity, how we age and the complex behaviour of crowds.

Professor Stephen Simpson takes us on a strange journey that begins in the midst of a locust swarm and ends with the human obesity epidemic. Along the way you will see what you can discover by ticking a locust's leg with a paintbrush, how recreational drugs turn shy solitary locusts into swarming party animals, how aircraft are being used to track swarms, the sinister role played by cannibalism in locust swarms and how a powerful appetite for protein can explain not only locust mass marching but also human obesity and ageing.

The herbivore's dilemma: to eat or be eaten   View Summary
20 February 2013

Join us for this special lecture by Dr Clare McArthur as part of the 50th birthday celebrations for the School of Biological Sciences.

As Ulysses sails home, he is confronted with many perils. Negotiate poorly and he is either attacked by Scylla, the six-headed monster, or drowned in the swirling whirlpools of Charybdis. Like Ulysses, herbivores must negotiate their own perils — and not just once, but every time they go out for a meal. On one hand, they may be poisoned by the plants they eat, and on the other, they may themselves be eaten by predators; provoking the never-ending daily dilemma of what to eat without being eaten.

Using captive and free-ranging leaf-eaters (Australian brushtail possums) and free-ranging fruit-eaters (African thick-tailed bushbabies), Associate Professor Clare McArthur will demonstrate how these animals solve the foraging dilemma by changing their behaviour and use of food patches in response to the interplay between toxin concentration and patch safety. You will be surprised at how the animals detect, quantify and compare the costs of food and fear and, by manipulating the quality of food patches, Clare can pinpoint where the animals consider the two costs to be equal.

Finally, you will see how the personality of individual animals may shift the foraging balance between food and fear, with implications not just for individuals, but for ecological populations and communities.

School seminar series: Cooperative breeding: long-term studies in the time of twitter   View Summary
15 March 2013

Andrew Cockburn (Division of Evolution, Ecology & Genetics, Research School of Biology, The Australian National University)

Cooperative breeding, where more than two individuals combine to rear a single brood ofoffspring, is one of the major problems of evolutionary biology, as some carers must be provisioning offspring that are not their own. Cooperative breeding has evolved hundreds of times in birds, and has been investigated with many of the most intense long-term studies of any wild organisms. This seminar will probe two unresolved problems and a unique opportunity that emerges from these studies. The first problem is why has an 'ecological' predictor for cooperative breeding has remained so elusive. Second, I will show that sexual conflict is a common consequence of the evolution of cooperative breeding, necessitating theory that explains how these societies often remain extremely stable despite such conflict. I will then demonstrate how the unique data sets that emerge from the study of cooperative breeding afford unique opportunities to probe other important theoretical questions in evolutionary ecology. I willillustrate this opportunity by describing how massive pedigrees of superb fairy-wrens can be used to illuminate the troubling question of how geneticvariation can resist depletion when females impose strong selection throughmate choice, and how this leads to a new theory of how condition-dependence and sexual signalling interact.

School seminar series: The causes and consequences of variation in dispersal distance   View Summary
22 March 2013

Winsor H. Lowe, Associate Professor, Division of Biological Sciences, The University of Montana, Missoula, MT 59812, USA
Visiting Associate Professor, Australian Rivers Institute, Griffith University, Nathan, Queensland 4111, AU
Email: winsor.lowe@umontana.edu

Dispersal is a fundamental process in population biology, ecology, and evolution. In most species, dispersal distributions are characterized by many individuals that remain close to their origin and large variation in the distances moved by those that leave. Darwin saw that long-distance dispersal played a key role in range expansion, and models show that dispersal distance can strongly affect population and community dynamics. But despite these wide-ranging implications, we have little understanding of how variation in dispersal distance is maintained in natural populations and, more specifically, the fitness consequences of long-distance dispersal. My research uses a stream salamander system to address these gaps in our understanding of the proximal causes and consequences of variation in dispersal distance. This work does not support the widely held view that fitness consequences of long-distance dispersal are unpredictable, and instead suggests that consistent evolutionary mechanisms may explain the prevalence of long-distance dispersal in nature.

School seminar series: Multiple functions of hibernation and daily torpor   View Summary
12 April 2013

Fritz Geiser (Centre for Behavioural and Physiological Ecology, Zoology, University of New England, Armidale, NSW 2351, Australia. fgeiser@une.edu.au)

Although energy conservation by cold-climate adult endotherms in winter is often viewed as the main function of torpor, recent evidence suggests that this may not always be the case and other functions of torpor may be equally or even more important in some instances. Daily torpor and hibernation, which are used by mammals and birds from all climate zones, permit prolonged female sperm storage in bats, allow reproduction with limited or fluctuating food supply, and delay parturition until more favourable periods. Torpor appears to increase the efficiency of energy and nutrient use during development and also enhances fat storage during migration. Further, torpor reduces water requirements, appears to ensure persistence during droughts, permits co-existence of competing species, and also reduces the risk of predation and mammalian extinctions. Thus, the functions of torpor are diverse and go well beyond energy conservation in winter.

School seminar series: The cognitive dimension of insect social behaviour   View Summary
19 April 2013

Dr Mathieu Lihoreau, Postdoctoral Researcher, School of Biological Sciences and the Charles Perkins Centre, The University of Sydney.

Attempts to explain the origins of primate intelligence suggest that the computational demands of living in social groups require larger brains with enhanced cognitive capacities. Whether such reasoning can apply to all social animals is an open question. I'll discuss these evolutionary relationships in insects based on data about how bees solve factorial problems and flies build consensus with a brain the size of a pinhead.

School seminar series: Mutation, selection, and evolution   View Summary
26 April 2013

Presented by Dr Katrina McGuigan, School of Biological Science, The University of Queensland

Many different traits appear to be under selection, and all appear to have ample genetic variation. However, if variation in these traits contributed independently to fitness, and if mutations independently affected each trait, fitness would be implausibly low, and the mutation rate implausibly high. Theories exploring the evolution ofgenetic variation predict that standing genetic variation will be predominantly composed of low frequency alleles with deleterious pleiotropic effects on fitness. These theoretical expectations are consistent with different types of evidence, and have broad implications for understanding the targets of selection in natural populations. In this talk I will present data from experiments in the native vinegar fly, Drosophila serrata, exploring the effects of selection and mutation on genetic variation, and on the evolution of traits.

Keast Lecture: Beauty and the beast - the evolutionary ecology of male reproductive antics   View Summary
10 May 2013

Dr Bob Wong (Biological Sciences, Monash University) presents the 2013 Keast Lecture.

Dr Bob Wong, Keast lecturer for 2013.
Dr Bob Wong, Keast lecturer for 2013.

The reproductive interests of males and females rarely coincide. The idea of reproduction as a cooperative and harmonious venture between the sexes is a fallacy - the animal world is, in fact, rife with sexual conflict. So how does this conflict play out when it comes to finding a suitable mate?

Traditionally, males are thought to maximise their reproductive pay offs by mating with as many females as possible. Indeed, in most species, males will compete vehemently with each other for access to mating opportunities. For females, however, it's more a case of quality rather than quantity, with evidence suggesting that females maximise their reproductive success by being selective over their choice of mating partners.

Both mechanisms - male competition and female mate choice - underpin sexual selection, the process first proposed by Charles Darwin to explain the evolution of elaborate secondary sexual traits, such as the beautiful plumes of the male bird of paradise and the claw waving antics of the fiddler crab.

So how do the two processes of sexual selection operate in practice? Are the biggest and most dominant males the best suitors for choosy females (as Darwin himself had originally surmised)? And are males as permissive when it comes to sex as traditionally thought? This talk will provide answers by drawing on recent insights into male reproductive strategies from the sexual selection literature.

 
School seminar series: The coevolution of fig trees, pollinators and parasitoids   View Summary
17 May 2013

Presented by Prof. James Cook, Hawkesbury Institute for the Environment, UWS (Host: A/Prof. Dieter Hochuli).

Symbiosis - the intimate ‘living together’ of different species - plays a huge role in both evolutionary innovation (e.g. the origin of plants) and ecosystem function (e.g. nitrogen fixation). Symbiosis is very common in nature and intimately interacting species are likely to influence each other strongly in terms of both adaptation and speciation. Many host-symbiont interactions are antagonistic, but others are mutualisms in which both partners derive benefits. A classic case involves fig trees, which provide a year-round supply of fruit to diverse animals, from tiny insects to bats, birds and elephants. This ecosystem function relies on an obligate pollination mutualism between fig plants and tiny fig wasps. I will discuss the origin and patterns of speciation in figs and fig wasps during their radiation to produce >750 species pairs spread across all tropical continents. This research supports substantial long-term co-speciation, but also additional modes of speciation in the wasps. I will also describe how the intricate symbiosis with fig trees has influenced genome evolution in the pollinators. I will then present a striking pattern of coadaptation between the pollination behavior of the wasps and floral sex ratio in the figs. Finally, I will consider how climate change impacts upon this intricate symbiosis, both in terms of immediate ecological population dynamics, and longer-term adaptation and speciation.

School seminar series: Marine fish nurseries - baby paradise or Hobson's choice?   View Summary
24 May 2013

Presented by A/Prof. Ivan Nagelkerken, Marine Biology, University of Adelaide.

Various animal species show a stage-structured life cycle where individuals occupy spatially separated juvenile and adult habitats during different life phases. In the marine seascape one such example is that of fish species which use mangrove and seagrass habitats as juvenile nurseries and live as adults on coral reefs. While the appreciation for this phenomenon has increased significantly over the last two decades, empirical data that provide an understanding of the underlying mechanisms are still largely lacking. We still know little about the way in which settlement-stage oceanic fish larvae locate and navigate towards inshore nursery habitats, the costs and benefits of such a life-history strategy, what triggers movement from nurseries to the adult habitat, and the degree to which these fish replenish adult populations and colonize distantreefs. The latter has important consequences for management of fish stocks and marine reserve design. During this presentation, recent advances in this field will be presented, based on a variety of laboratory and field experiments using a range of research methods (e.g., habitat choice experiments, stable isotopes, modeling). In contrast to the general belief, use of specific nursery habitats is based on trade-offs between various life history traits. Nevertheless, maintenance of ecosystem connectivity is important for successful replenishment of populations of a variety of economically and ecologically important species and can enhance the functioning, productibility, and resilience of coastal marine ecosystems.

 
School seminar series: Reading macroevolutionary patterns from molecular phylogenies   View Summary
31 May 2013

Presented by Prof. Lindell Bromham, Research School of Biology, ANU (Host: A/Prof. Simon Ho)

The term "macroevolution" is generally used to describe changing patterns of biodiversity over time, space or lineages, as opposed to microevolution which focuses on changing allele frequencies in populations. The debate over whether macroevolutionary patterns lead to inference of mechanisms that cannot be explained by microevolutionary processes has been simmering for at least 150 years. Discussions of macroevolution have lately been reinvigorated by the study of patterns of diversity from molecular phylogenies. The beauty of molecular phylogenetic analyses is that they provide a way of examining genome-level, population-level and lineage-level patterns in a single analysis. I will illustrate this approach to using molecular phylogenies in macroevolutionary studies with three examples: the relationship between molecular change and diversification; rates of molecular evolution in parasites; and the evolution of salt tolerance in grasses.

June
School seminar series: Adventures in nutrient space   View Summary
7 June 2013

Presented by Prof. David Raubenheimer, School of Biological Sciences, Faculty of Veterinary Science, and Charles Perkins Centre, University of Sydney.

At face value, the challenge of eating sensibly is relatively straightforward: put enough of the right foods in your mouth and you've done the job. But scratch the surface, even lightly, and you will unearth a staggeringly complex tangle of interrelated questions. What, for example, are the right foods, and why these and not others? How much is enough of each, and how does this change with recent eating experiences and with other circumstances? How can you minimise the consequences of eating the wrong foods or too little or too much of the right foods? Such problems are solved on a daily basis by animals from insects to humans, but big challenges remain for researchers to understand how this done. In this seminar I will introduce a simple geometric device, the nutrient space, which has been invented as an aid to dealing with the complexities of nutrition. After discussing the basic concepts surrounding the nutrient space, I will provide "proof of concept" from tightly controlled laboratory experiments. Using studies of wild baboons, giant pandas, spider monkeys and mountain gorillas, I will then demonstrate that the nutrient space concept can help us to understand foraging not only in the lab, but also in the much more challenging setting of the field. Along the way I will show that the nutrient space can also help to understand the bizarre nutritional ecology of our own species.

Dr Bruce Stillman, President of Cold Spring Harbor Laboratory, will deliver the 2013 Murray lecture.

We take it for granted that our DNA replicates normally in our cells every day, but when these processes go wrong in our body's cells we can end up with abnormal cells, the wrong rate of cell replacement and even cancer. When DNA replication goes wrong in a developing baby, it can cause primordial dwarfism, microcephaly or a small brain.

In the annual Murray Lecture, Professor Bruce Stillman, President of Cold Spring Harbor Laboratory in New York, will discuss how the human genome is copied and inherited each time a cell divides. Professor Stillman's research has elucidated the mechanism of how a cycle of copying the DNA double helix is initiated and how it is coordinated with chromosome segregation during mitosis - when a normal body cell segregates its chromosomes to form two identical body cells.

Delve deep into your cells and find out how important DNA replication is to you every day.

School seminar series: Nutritional immunology: A multidimensional approach   View Summary
23 August 2013

Dr. Fleur Ponton, School of Biological Sciences, The University of Sydney

Nutrition is critical to immune defence and resistance to pathogens, with consequences that affect not only the health, welfare and reproductive success of individual organisms, but also have profound ecological and evolutionary implications. My research focuses in better understanding the network of interactions that define the relationships between nutrition, immune function, infection, and microbiota to provide a more comprehensive and robust understanding of the key determinants of the outcome of host-pathogeninteractions.

 
School seminar series: Seriously weird stuff in South African honeybees   View Summary
30 August 2013

Social cancers, paternal imprinting, genome elimination

On the southern tip of South Africa there dwells a little black honey bee called Apis mellifera capensis. It's not nearly so fierce as its yellow cousin to the north, the infamous 'killer bee' (Apis mellifera scutellata), but it is none the less extraordinary in its own way. Unlike all other honey bees, when an unmated worker lays an unfertilised egg it develops not as a male, but as a female, a clone of its mother. This provides workers with extraordinary opportunities for reproductive cheating, which they do with alacrity. It also provides researchers with the opportunity to study some remarkable evolutionary phenomenon. I will discuss three of them. 1) Reciprocal crosses between A. m. scutellata and A. m. capensis suggest that Capensis males epigenetically modify their sperm to increase the size and reproductive capacity of their worker offspring. 2) A clonal lineage of Capensis workers that has infested the beekeeping industry for over 20 years has retained heterozygosity without sex. This lineage provides the opportunity to answer a controversial question in evolutionary biology: why is fitness so often correlated with heterozygosity? 3) Is the foraging behaviour of modern social insects controlled by the same gene network that once regulated the reproductive cycle of solitary insects?
