About

Jennifer has broad interests in the ecology and early life history of marine fishes, as well as the potential for animals to cope with future climate change. Her research to date has focused on the ecological impacts of climate change to marine fishes and the potential for species to acclimate to the predicted environmental changes. To tackle these questions she use temperature controlled aquarium systems to maintain fish under elevated temperatures for years and generations to test the longer term impacts of warming ocean on marine fish. Jenni utilizes state of the art aquariums systems at both Sydney Institute of Marine Science and James Cook University to test the impacts of elevated sea water temperature.

Jenni's research concentrates on understanding the importance and prevalence of developmental plasticity, when fish experience warmer conditions in the first months of life, as well as the potential for acclimation across generations, when parents and grandparents are kept under elevated temperature conditions for their entire life. Her continuing research will expand our knowledge of how marine fishes throughout Eastern Australia (temperate to tropical) may cope with climate change through both developmental and transgenerational acclimation.

Phenotypic and adaptive responses to environmental change

Indicative Funding: $710,470 over 4 years
Summary: Projecting the response of species to future environmental change is essential for appropriate human management and conservation strategies. However, we currently lack knowledge on whether populations differ in their capacity to respond to climate change. This project will explore the capacity for various populations of reef fish to acclimate and adapt to ocean warming across generations and between populations. This project will also explore whether short term heatwave experience results in any adaptive benefits.

Australian Society for Fish Biology - Michael Hall Student Innovation Award

Incorporating evolutionary perspective into conservation: An assessment of local adaptation across the range of a coral reef fish

Indicative Funding: $1,000 over 1 year
Summary: The aims of this research project are to gain an increased understanding of how different populations across the species? range of Acanthochromis polyacanthus will respond to ocean warming. Specifically, I will 1) determine the levels of local adaptation across three different regions within the species range to reveal the thermal performance landscape, and 2) identify cellular mechanisms that underlie adaptive difference between populations. This research will allow identification of populations and/or reef regions that have increased adaptive ability and could be potential targets for conservation action.

Incorporating evolutionary perspective into wildlife conservation: An assessment of local adaptation, genetic differentiation, and heritability in a reef fish (Acanthaochromis polyacanthus)

Indicative Funding: $6,695 over 1 year
Summary: For many sedentary organisms with low dispersal ability, response to climate change depends on their capacity for local adaptation and phenotypic plasticity to maintain populations in changing environmental conditions. These evolutionary processes may vary across populations, resulting in uneven responses to changes within a species? range. To understand a species? evolutionary trajectory under climate change it is important to quantify the magnitude of local adaptation, genetic differentiation, heritability, and phenotypic plasticity in populations throughout its range. This project aims to understand how these evolutionary processes vary across a latitudinal gradient in a reef fish (spiny chromis damselfish; Acanthochromis polyacanthus).

Exploring the nexus between behaviour and physiology of coal reef fishes in a warming world

Indicative Funding: $39,887 over 3 years
Summary: With 15 or the warmest 16 years on record having occurred since 2001, mankind is already witnessing the devastating effects of rising ocean temperatures on coral reef ecosystems. This project will improve the accuracy of climate-sensitivity foecasts for key reef fisheries species by asking: can reef fishes use behaviour to buffer the effects of ocean warming? We go beyond conventional lab-based testing of species' thermal tolerances, utilizing advances in biotelemetry technology to obtain field measures of thermal ecology, and testing for thermal physiological plasticity over relevant timescales. Our research is the first in the world to explore the possibility of behavioural thermoregulation in reef fishes, and will provde an enhanced understanding of the impacts of climate change on reef ecosystems.

Battle of the sexes in a warming ocean ? which parent has the greatest impact?

Indicative Funding: $18,051 over 1 year
Summary: Rising sea temperature poses a significant threat to coral reefs and their inhabitants. By 2050 ? 2100, sea surface temperature of coral reefs, including the Great Barrier Reef, is expected to increase by 1.5?C (IPCC 2007; 2013). While current populations of reef fish suffer when exposed short-term to elevated temperatures, future warming will occur over numerous generations for most species. Research has shown that the performance of fish improves when their parents also experience warmer conditions (known as transgenerational acclimation). The next key question is what combination of parental experience is required to obtain improved performance in the next generation (i.e. only mothers, fathers, or both parents)? This information will directly enhance our ability to predict generational rates of acclimation, especially where mating pairs are formed by individuals of diverse ages. As well as gain valuable insight into the mechanisms behind acclimation.

Transcriptional program and the epigenome of transgenerational acclimation in reef fishes

Indicative Funding: $631,579 over 3 years
Summary: Transgenerational acclimation is a form of non-genetic inheritance in which the environmental conditions experienced by one-generation influences the performance of future generations in that environment. New studies show that the performance of juvenile fish at higher water temperatures is significantly improved when their parents also experienced the warmer temperature. However, the molecular mechanisms responsible for transgenerational thermal acclimation, and how it is controlled, are currently unknown. Genomic DNA methylation is a form of epigenetic inheritance that cells use to control gene expression, and recent evidence suggests that genome methylation can be driven by external signals in cells after birth as well as in adult cells. This raises the intriguing possibility that DNA methylation can serve as a mechanism for genomes to rapidly adapt to changing environments. Here we propose a unique multi-generational manipulative experiment for a common coral reef fish, Acanthochromis polyacanthus, with genome-wide measurements of gene expression and DNA methylation. Using an integrative analysis, we seek to identify molecular pathways responsible for transgenerational acclimation to rising ocean temperatures and to test the hypothesis that genomic DNA methylation serves as a central mechanism mediating transgenerational acclimation to climate change.
