CIE Seminar Series – 2019: Avian body size and climate change

SPEAKER: Dr Janet Gardner, Australian Research Council Future Fellow, Research School of Biology, The Australian National University, Canberra

DATE: Friday, 22nd November 2019

TIME: 1:30pm

LOCATION: Geelong Campus at Waurn Ponds – Room ka4.207 (Green room)

Seminar will also be video linked to the following campuses: Melbourne Campus at Burwood –Burwood Corporate Centre and Warrnambool Campus, Room J2.19 (Fishbowl)

ABSTRACT.

Changes in animal body size have been hailed as a third universal response to recent climate change, alongside changes in species’ phenology and distributions. Changes in body size have important implications for the thermal tolerances and energetics of species and thus for individual fitness and population dynamics.

Using Australian birds as a model system, we integrate long-term morphometric data sets (from museum collections and generated by citizen science) with climate data and molecular phylogenies to investigate spatial and temporal patterns of trait change and test underlying mechanisms at a continental scale.

In this talk I outline progress in understanding this phenomenon and the implications of our results for identifying species’ sensitivities to climate change.

BIO.

Janet’s research integrates several complementary approaches to investigate the links between environmental variation, individual fitness and demographic change, factors that ultimately determine the abundance and distribution of species.

Janet was awarded a PhD from the ANU in 2003, was appointed as an Associate Lecturer at ANU in 2004, then as a Research Associate in 2006. Since 2008 she has held several Research Associate positions at CSIRO and Monash University. She returned to ANU in 2015 and is currently an ARC Future Fellow in the Research School of Biology

Appointments with speaker may be made via kate.buchanan@deakin.edu.au.

Please note: Janet will be staying in Torquay on Thursday and going out to dinner at Roku Den on Thursday evening. On Friday we will have lunch at Natural 1 12-1pm before the seminar. Janet will have time both before and after her seminar to chat, so please let me know if you would like to have a short chat with the speaker. Please let Natasha know if you would like to attend one of the meals.


External visitors – wish to join us and connect to our seminars?

External parties may connect to the live seminar via *N SEBE VMP LES Seminars 52236958@deakin.edu.au [ID.36958] via the methods listed below:

  • For external guests, you can connect as a web guest by clicking HERE. If using Chrome you it will prompt you to install the Cisco Jaba Plugin, then it will prompt you to download the extension which you will need to install. Once this has been installed, you will have a black screen with a call button. You will just need to click call and it should connect into the VMP.
  • For Deakin staff and students, please join via Skype for Business (Lync) – if you have office installed you may already have Skype for business or Lync installed. You just need to look for it on the start menu. If you find it, you can log into skype using your Deakin email and password and then dial 36958.
  • Could not log in? More info on how to connect is available HERE or HERE.
  • From a mobile phone or landline: call +613 92517000, wait for the prompt, then enter the five digit VMP number (36958)
  • Please note that connection is only available while a seminar is taking place.

As a courtesy, we request that when connecting to the seminar that you mute your microphone unless you are required to speak, this would ensure that the sound from the speaker to the audience is not disrupted by feedback from your microphone – thank you!

CIE Seminar Series – 2019: Alarm calls, eavesdropping and deception

SPEAKER: Professor Rob Magrath, Professor of Behavioural Ecology, Australian National University, Canberra

DATE: Friday, 15th November 2019

TIME: 1:30pm

LOCATION: Geelong Campus at Waurn Ponds – room ka4.207

Seminar will also be video linked to the following campuses: Melbourne Campus at Burwood –Burwood Corporate Centre and Warrnambool Campus, Room J2.19 (Fishbowl)

ABSTRACT.

Many species of birds and mammals eavesdrop on the alarm calls of other species, and so gain information on danger but also expose themselves to the risk of deception. First, I consider how animals recognize the meaning of other species’ alarm calls. Contrary to intuition, alarm calls don’t all sound similar and may not be intrinsically scary. Instead, individuals commonly respond to familiar but not unfamiliar alarms, implying learning.

I describe experiments to test for learned recognition by Australian birds, including through social learning. Second, paying attention to the alarm calls of others means that you are vulnerable to deceptive use of alarm calls by those species. This commonly entails individuals giving false alarm calls and then stealing food dropped by victims that have fled. I describe a different context, in which the tiny brown thornbill deceives the much larger pied currawong during attempted nest predation.

Overall, our findings reveal how learning can help explain the widespread eavesdropping networks in natural communities, and allow the complex web of information and deception.

BIO.

Rob Magrath is a Professor of Behavioural Ecology at the Australian National University. In recent years his group has focussed on studying acoustic communication and eavesdropping in Australian birds.

We’re interested in both the design and function of signals, and have studied communication about danger, parent-offspring communication, vocal mimicry and duetting.
