Ecology Environment

Ecology Environment

Ecologists combine biology, physical geography, environmental science and Earth science to study interactions among organisms and their environment.

At Macquarie, you’ll take advantage of our unique interdisciplinary ethos to answer questions on ecosystems and biodiversity, and to inform our conservation efforts.

Professional experience

At Macquarie University, learning doesn't just happen in the classroom. Through Macquarie University's unique PACE program you can gain practical experience in the industry of your dreams well before you graduate and get ahead of the career queue.

Through PACE, you can take a step into the workplace and put your theoretical knowledge to the test alongside industry partners and mentors. Ecology students are offered the opportunity to work with a range of leading industry researchers and partners in on-campus, local, regional and international environments. Previous students have assessed the health and condition of mangroves at Sydney Olympic Park.

“It’s a fantastic opportunity to choose your own adventure. And to work on something that has real-world applications and can potentially make a difference.” – PACE alumus, Sam Shumack

No matter what you decide to study at Macquarie, PACE has an activity for you. Learn more about the opportunities available through PACE.

Student experience

Recognition for Prior Learning (RPL)

You can get Recognition for Prior Learning (RPL) for study that did not culminate in an award and some previously completed qualifications. Macquarie University will automatically count your previous study as general credit points (at 100 and 200 level, and sometimes at 300 level). If your prior study includes material that is essentially the same as a Macquarie unit, then you can apply to have this unit exempted. To do so, see Recognition for Prior Learning.

Can my prior study be counted towards specific credits for units at all levels (100, 200 and 300), or are there restrictions?

In previous years, Macquarie only granted credit at 100 and 200 level. This has now changed so that it's possible to apply for up to six credit points (two units) of credit at 300 level. If in doubt, please speak with an adviser.

Can I get RPL for units I studied for a TAFE diploma?

In some cases, you can. See more information on RPL. It's important that if/when you do apply that you provide as much information as possible on the courses/units that you've completed at TAFE.

Kick start your technical lab skills workshops - February 2016

Open to students studying at Macquarie University in 2016

The Kick start your technical lab skills workshop is for students who are studying science at Macquarie University but did not study science at HSC level; for those needing to gain confidence in their technical lab skills; and for those students who want a refresher course in technical lab skills.

The laboratory skills workshop will develop a range of practical skills for the science laboratory, delivered ahead of the formal learning period. A suite of techniques will be demonstrated and practiced across two intensive days. Students during the two-day period will be asked to follow set procedures and methods, and apply well-developed technical skills, basic scientific knowledge and become familiar with Work Health and Safety requirements.

Scholarships and prizes 

Barbara Rice

Rice Memorial Fund

The Rice Memorial Fund was established by donations following the death of Barbara Rice in 2009. It honours her memory by encouraging field research. Distributions from the fund support two prizes, named “Rice Memorial Field Research Award” and “Rice Memorial Field Research Proposal Award”.

The Rice Memorial Field Research Award is determined by a Selection Committee at the annual postgraduate conference of the Department of Biological Sciences. All postgraduate research students enrolled in Biological Sciences and giving presentations at the conference and describing research with a substantial fieldwork component are considered as candidates. Field research is interpreted as meaning research undertaken in outdoor environments where wild populations of the study organisms occur. Criteria are the quality of the research, plus the effort and challenge of the fieldwork, plus liveliness and clarity in the conference presentation.

The Rice Memorial Field Research Proposal Award is given for an annual report that incorporates the best proposal towards field research during the forthcoming year.

If the Selection Committee remains undecided between candidates on the basis of other criteria, then preference may be given to candidates whose research or proposal is about plants on land. This preference recognizes Barbara Rice’s personal research in terrestrial botany, but is not to override the major criteria of research excellence and field activity.

Each Award is to be given to a single candidate and not divided. A student may win either Award on more than one occasion, but not for the same fieldwork or proposed fieldwork. The Selection Committee may decide not to make one of the Awards in any given year, taking into account the quality of the candidates and the financial situation of the Fund.

Tony Price Award

In the late 1970s, local Auburn resident Greville Anthony (Tony) Price (1934–2010), recognised the value of the vegetation of Duck River and Rookwood Cemetery in Auburn, both for the species they held and the clues they could give to past vegetation patterns. He spent three years surveying and collecting plants in the area and compiled an extensive list of the existing plant species, recorded ecological observations, and interpolated them into a picture of the landscape and vegetation of the district at the time of European settlement. 

Tony Price was a student in the (then) School of Biological Sciences at Macquarie University in the 1980s. Tony Price was widely consulted for his botanical knowledge, and his ecological work and opinions provided baselines for research, as well as environmental management by councils, catchment authorities, community groups and others, both locally and within the wider district. He was a founding member of the Friends of Duck River Reserve whose activities included: petitioning for interpretative signage; instigating fencing of the area to protect it from minibike riders and overflow parking at the Melita Soccer Stadium; gaining funding for the removal of old car bodies from the reserve; ensuring the retention of trees along the riverbanks; propagating local species and undertaking bush regeneration work. Tony Price left a small bequest to Macquarie University to support future plant ecology research. 1

The Milthorpe Postgraduate Award

This scheme is supported by a bequest to the (then) School of Biological Sciences by the family of Fred Milthorpe. Professor Milthorpe was a Founding Chair in the School of Biological Sciences. He was a plant physiologist in the classical sense, influencing a generation of plant scientists here and abroad. His research revealed underlying biological processes that are critical to forestry, agriculture and horticulture. His philosophy was to make discoveries by inspiring postgraduate students to be curious about their research questions and thoughtful about how they execute them. This award aims to foster these philosophies. The maximum amount of the award is $1500 and the award is offered in alternate years.

Locally referred to as The Hill, the area is committed to non-intrusive research, such as learning to avoid predation, and natural animal behaviours.

Vertebrates (birds, fish, reptiles) or invertebrates (bees, flies, spiders) are observed in natural settings with minimal disruption to their normal environment. This allows the researchers to verify findings they have documented in the field. Other areas of investigation are water ecology and the competitive abilities of native trees.

The primary focus of the research is to determine how evolution has effected the development of brains by observing the animal's behaviour as they interact with their environment in competition with their own and other species.

Research has a strong focus on conservation and environmental protection and all work with vertebrates has been approved by the Animal Ethics Committee.

Using data collected over 18 years on nearly 7000 females, researchers from Macquarie University, the University of Tasmania, CEFE-CNRS, and the University of Oxford, show that young females have a lower chance of survival following their first breeding event compared to experienced breeders or non-breeders.

Moreover, females starting to breed early, for example at age three, are even less likely to survive to the following year than females first breeding at age four.
Lead researcher Marine Desprez from Macquarie University says given the number of southern elephant seals at Macquarie Island has been in decline for many years, the loss of young female seals has grave ramifications.

“The age at which individuals first reproduce is an important factor that may be the most important determinant of a female seal’s lifetime reproductive output, which in turn can have major consequences on population dynamics.

“Elephant seals are apex predators, at the top of the food chain. They integrate the resources available within the southern ocean, making them critical indicators of the productivity and health of the ocean.

“Currently, their population is declining at a rate of 0.8 per cent per year, and an earlier study estimated that since 1988, there has been a reduction of approximately 5400 breeding females.

”Female elephant seals fast while they feed their pup, during a lactation period that lasts about 24 days. This quickly leads to a reduction in body mass, on average of 35 per cent. They can lose up to a costly 8kg a day.”

Reproduction is even more costly for the young first-time mums because they are still growing when they first breed. Female elephant seals grow until six years of age, so at three are still young and generally smaller. Growing animals must allocate energy to both growth and reproduction, therefore only the strongest and healthiest first-time mums will survive their first breeding event.

“This study is a first step in understanding the long-term decline of the population of elephant seals at Macquarie Island. The more we understand the elephant seals’ life, the better we may be able to prevent their decline,” said Marine.

“Our next step is to investigate if there is a link between the decline of the population and the environment in which the seals live and then to predict how the population will evolve in the future.”

The full research paper “Age-specific cost of first reproduction in female southern elephant seals,” has been published by Biology Letters.

The collaborative study, led by Dr Gabriel Yvon-Durocher from the University of Exeter, with contributions from Macquarie University’s Dr Drew Allen, collated data from hundreds of laboratory experiments and field surveys to demonstrate that the speed at which methane fluxes increase with temperature was the same whether single species populations of methanogens, microbial communities or whole ecosystems were analysed.

Dr Yvon-Durocher said: “This is important because biological methane fluxes are a major component of global methane emissions, but there is uncertainty about their magnitude and the factors that regulate them. This hinders our ability to predict the response of this key component of the carbon cycle to global warming. Our research provides scientists with an important clue about the mechanisms that may control the response of methane emissions from ecosystems to global warming.”

Methane is an important greenhouse gas because it has 25 times the global warming effect of carbon dioxide. The production of methane in freshwater ecosystems is brought about by an ancient group of microorganisms called Archaea that exist in waterlogged sediments where there is no oxygen. They play an important role in the decomposition of biomass, but rather than producing carbon dioxide, they produce methane as a by-product of their metabolism.

The report, published in the leading scientific journal Nature, also showed that the temperature response of methane production is much higher than respiration (production of carbon dioxide) or photosynthesis (consumption of carbon dioxide), indicating that global warming may increase the amount of methane relative to carbon dioxide emitted globally from aquatic ecosystems, terrestrial wetlands and rice paddies.

Dr Yvon-Durocher, from the Environment and Sustainability Institute at the University of Exeter’s Penryn Campus in Cornwall, added: “The discovery that methane fluxes are much more responsive to temperature than the processes that produce and consume carbon dioxide highlights another mechanism by which the global carbon cycle may serve to accelerate rather than mitigate future climate change. However more research, using our results as a platform for refining Earth system models, is required to explore the consequences of our findings for future levels of climate change.”
