Representing Our Research at the 42nd Mid-Continent Paleobotanical Colloquium
Representing Our Research at the 42nd Mid-Continent Paleobotanical Colloquium
This past month, two of our very own PhD students, Catarina (me!) and Antonietta, travelled to Middletown, Connecticut, to present at the 42nd Mid-Continent Paleobotanical Colloquium, hosted by Wesleyan University (Go Cardinals!).
Antonietta delivered a well-received talk titled “Regional Plant Ecological Turnover and Diversity Loss at the End-Triassic Mass Extinction at the Jameson Land Basin, East Greenland” and fielded more questions than any other speaker!
Catarina, despite battling jetlag, presented a poster titled “Sampling Strategies and Their Influence on Paleoecological Interpretations at the Triassic–Jurassic Boundary”, a follow-up to her earlier IGRM presentation.
Reflecting on the experience, Antonietta shared, “Visiting the palaeobotany collections at museums of such importance as the Yale Peabody Museum was an absolutely amazing experience.” Catarina added, “It was great getting to meet everyone and share the work we’ve been doing with our American peers — and to see what they’ve been working on as well!”

Flatlining Fens - Signs of homogenisation beneath the surface
Fine-scale ecosystem variation signals early functional decline in alkaline fens, new research shows
New research from the discipline of Botany, in collaboration with the Engineering Department and the National Parks and Wildlife Service (NPWS), reveals that some of Ireland’s rare alkaline fens—peat-forming, groundwater-fed wetlands—are becoming more uniform, or “homogenised,” due to historic drainage and degradation.
Led by Dr Sate Ahmad, the research team compared a relatively intact fen in Westmeath with a degraded one in Limerick and found striking differences. While both had high levels of organic matter, the degraded site held significantly less water and showed far less microvariation in soil and surface features. The team discovered that the degraded fen had become much more spatially uniform—a red flag for ecological health. These differences hint at a loss of the ecosystem’s ability to perform vital functions. The findings highlight the importance of microtopography—the tiny bumps and dips in fen surfaces—as early indicators of damage and recovery. They also underscore the value of small-scale mapping and monitoring in ecosystem restoration.
As Ireland works to restore and protect its remaining peatlands, the study offers new tools to measure restoration success and ecosystem complexity. The study was funded by Research Ireland (formerly Irish Research Council) New Foundations Award in partnership with Sunflower Charitable Foundation and Community Foundation Ireland.

Unearthing Memory - Siobhan McDonald’s Artistic Dialogue with Nature
Merging Science and Art - Siobhan McDonald’s Collaboration with Terraform in BOGSKIN
Siobhan McDonald’s latest work explores the intricate balance between preservation and decay, drawing inspiration from the bog ecosystems that have safeguarded organic matter for centuries. Working in collaboration with Terraform, she engaged with leading ecological research and material preservation techniques to deepen the scientific foundation of the project. Their expertise provided critical insights into the anaerobic conditions that allow materials such as sphagnum moss, peat, and decaying plant matter to endure over time, mirroring the way the Faddan More Psalter was preserved within the bog.
As part of this process, Siobhan utilized the cutting-edge facilities of the Variable Atmosphere and Light (VAL) laboratory at Trinity College Dublin. The VAL Lab’s advanced plant growth chambers, designed to control light intensity, spectra, temperature, humidity, and atmospheric composition, enabled her to cultivate and study plant materials under precisely simulated environmental conditions. This scientific approach allowed for an innovative integration of organic materials and artistic expression, reinforcing the themes of memory, transformation, and impermanence within her work.
Further supported by Terraform’s ERC-funded research, Siobhan incorporated experimental methods to investigate the interplay of light, organic matter, and time. These techniques expanded the possibilities of her practice, pushing the boundaries of material exploration while maintaining a strong connection to ecological and historical narratives.
The results of this research and artistic exploration are currently on display at the Royal Hibernian Academy of Arts in Dublin. Her latest exhibition, BOGSKIN, is open to the public until April 20th 2025, offering a unique opportunity to experience the interplay of science, art, and the fragile ecosystems that inspire her work.
Looking ahead, Siobhan will continue her collaboration with Terraform as she embarks on a new project examining Dublin’s coastline as a wetland. This work will form part of the upcoming STARTS4Water II residencies, furthering her engagement with environmental themes and the passage of time in shifting landscapes.

Harnessing botanical remedies for respiratory health
Plant-based cough syrup - a blend of tradition and science
Muhammad Siddiq, a PhD student, recently carried out a project exploring natural alternatives to synthetic cough syrups, with a focus on medicinal plants from the TCD Botanical Garden. This independent project, while separate from his doctoral research on plant chemistry and climate change, contributes to the broader conversation about the role of plants in healthcare.
Siddiq’s work focused on identifying plants with potential cough-relieving properties, drawing on both historical knowledge and scientific evidence. He highlighted five plants known for their medicinal value: Allium sativum (garlic), prized for its antibacterial and immune-boosting effects; Aloe vera, recognized for its soothing and anti-inflammatory properties; Equisetum hyemale (horsetail), a mild expectorant; Thuja occidentalis, traditionally used for respiratory congestion but requiring controlled use due to its thujone content; and Rubus armeniacus (blackberry), rich in antioxidants that help alleviate throat irritation.
Using these plants, Siddiq developed a natural cough syrup, blending garlic extract, aloe vera juice, horsetail infusion, blackberry syrup, and honey—an age-old natural remedy known for its preservative and throat-soothing properties. This simple yet effective formulation offers a plant-based alternative to commercial cough syrups and demonstrates the potential of botanicals in modern medicine.
Although separate from his PhD research, Siddiq’s work highlights the relevance of plant-based treatments in healthcare, bridging traditional knowledge with modern scientific validation. His project also emphasizes the value of locally available medicinal plants, many of which visitors to the TCD Botanical Garden can explore firsthand to learn about their historical and medicinal significance, both in Ireland and beyond.
