New publication: Acidity impacts on microbial diversity and litter decomposition for organic soils

Published on by Catharine

Upland areas of the UK were highly impacted by sulphur deposition during the acid rain era of the 1970s-80s. As these soils gradually recover from acidification, they have been loosing increasing amounts of waterborne carbon, known as DOC (dissolved organic carbon). This has resulted in surface waters in peatland catchments becoming increasingly browner in colour, and represents a notable carbon loss from these soils (which may eventually enter the atmosphere as carbon dioxide).

But why is this happening? There is a strong evidence base supporting a physiochemical mechanism in organic soils responding to changing acidity. Low acidity results in DOC ‘clumping’ together, bringing it out of solution, but increasing pH enables this organic material to dissolve back into the soil solution, making it mobile once more. However, are there other mechanisms behind this trend? After all, microbial decomposition of organic matter produces DOC, and conditions become more suitable for microbial activity with increasing pH.

In this study published in Plant and Soil, led by Dr Catharine Pschenyckyj, we assessed the impact of changing acidity on microbial communities and decomposition of dead plant material (as a proxy for DOC production). This was part of a wider long-term field experiment in the Snowdonia and Peak District regions, in which acid rain, and recovery, was replicated.

Interestingly, changing acidity didn’t significantly impact the decomposition rates, DOC production, or microbial diversity. However, decomposition was faster in podzol soils compared to peat soils, leading to higher DOC production. This suggests that soil type and its physical and chemical properties play a bigger role in DOC release than decomposition. This study helps us understand the complex interactions in organic soil ecosystems recovering from acid pollution.

Published on by Catharine

PhD student Dilmi Mapatunage attended the IUCN Peatland Conference 2024, the largest gathering of 400 peatland experts, held in Aviemore, Scotland. The conference aims to showcase how the restoration of peatlands could pave the way towards transitioning into a green economy, and the role of healthy peatlands in supporting people and biodiversity by offering nature-based solutions.

The conference consisted of several plenary sessions on introducing the work of IUCN UK Peatland Programme and Peatland ACTION and delivering the key findings of the UK Peatland Strategy Report. Field visits to local peatland sites took place, to observe different peatland management and restoration techniques, combined with perfect weather and stunning views of the Scottish Highlands. Dilmi attended the Corr Riabhach demonstration site, which showcased peatland degradation and restoration efforts, such as erosion control and plant revegetation initiatives led by the United Nations. Dilmi presented a poster at the exhibition entitled, “Investigation of moorland burning and carbon dynamics for climate change mitigation”. Several delegates shared an interest in peatland burning and provided positive feedback and suggestions to refine and enhance the research.

The conference wrapped up with workshops and knowledge sharing sessions under different themes related to peatland management and restoration. Dilmi contributed to the ‘Translational palaeoecology and the art of collaboration’ workshop, engaging in discussions with a group of experts passionate about paleoecological records related to peatlands. Dilmi was inspired by the conference and looks forward to applying the feedback and suggestions received to further develop the research, and will attend more such meaningful conferences in the future.

New Study Addresses Nitrogen Accumulation in Soils for Better Environmental Management

Published on by Lisa

 

A TU-Durham University collaboration has yielded a detailed nitrogen budget to assess how nitrogen moves across different land uses in a large, mixed land-use UK catchment. This newly published work highlights the importance of accurately measuring nitrogen (N) accumulation to mitigate its harmful impacts on climate and ecosystems.

The Trent catchment, known for its extensive water quality monitoring, provided a unique opportunity to map nitrogen flows and pinpoint where accumulation occurs. One key finding was the higher nitrogen build-up in grassland subsoils compared to arable land, revealing the complex interactions between land use, nitrogen, and soil health.

Excess nitrogen in soil can lead to water pollution, loss of biodiversity, and increased greenhouse gas emissions, making proper nutrient management essential. This study advances our understanding of nitrogen dynamics, providing valuable information toward sustainable environmental management.

New Study Examines University Students’ Attitudes Toward Single-Use Plastics

Published on by Gillian

The widespread use of single-use plastics (SUP) is a growing environmental issue, particularly in Thailand, where plastic waste poses significant challenges. A recent study by Dr Oluseye Oludoye, focusing on Thai university students, explores the factors influencing their efforts to reduce plastic consumption, offering valuable insights for promoting sustainability. Using the Theory of Planned Behaviour, the research examined how attitudes, perceived control, and social influences affect students’ intentions at different stages of behaviour change.

The findings show that while positive attitudes towards reducing SUP are important, they only encourage action among students already contemplating change. In contrast, students’ belief in their ability to make a difference—perceived behavioural control—proved crucial across all decision-making stages. Social influences also played a key role in shaping initial attitudes, highlighting how peer dynamics can motivate change.

These insights are essential for educators and policymakers aiming to foster sustainable behaviours. Campaigns tailored to different stages of behaviour change can be more effective, and leveraging social influence through student-led initiatives could further encourage action. The study also suggests that reducing SUP might inspire students to adopt other sustainable practices. Overall, this research enhances our understanding of engaging young adults in environmental efforts and paves the way for a more sustainable future.

New research tackles single-use plastics in Thailand

Published on by Gillian

In our ever-evolving world, environmental sustainability has become a crucial topic of discussion. One of the most pressing challenges we face is the issue of single-use plastics (SUP). These materials, while convenient, have become pervasive in daily life, and their environmental impact is significant. In this context, a recent collaborative study shines a light on the pro-environmental behaviour (PB) of Thai communities regarding the reduction of SUP, particularly in food packaging.

Published in Scientific Reports, part of the Nature journal portfolio, the study was led by Oluseye Oludoye from Teesside University in collaboration with partners from Université Catholique de Louvain (Belgium), University of Lagos (Nigeria), Chulalongkorn University (Thailand), and University of California Davis (USA). It examined how residents from rural (Sichang Island) and urban (Nonthaburi city) areas of Thailand approach SUP reduction and what motivates their behaviour.

The study found that morality significantly influenced SUP reduction in both, rural and urban areas, but with an interesting twist. Rural residents were more driven by rational decision-making, while urban residents were motivated by moral values when choosing to reduce their plastic use. These insights are invaluable for policymakers looking to develop targeted sustainability initiatives that resonate with the specific motivations of different communities.

As we continue to face environmental challenges, knowing what motivates people to reduce plastic use can help create better solutions and encourage more sustainable habits in our everyday lives.

New Publication: Diversity of selected toll-like receptor genes in cheetahs (Acinonyx jubatus) and African leopards (Panthera pardus pardus)

Published on by Gillian

Leopards (Panthera pardus) and cheetahs (Acinonyx jubatus) face several threats including habitat destruction, human-wildlife conflict, and infectious disease. Dr Desiré Lee Dalton (Lecturer, Teesside University) and collaborators investigated the diversity of genes involved in the initial detection and defence against infectious diseases in modern Southern African cheetahs and leopards as well as historic cheetah samples and samples of different cheetah subspecies. We found that diversity was lower in cheetah than in leopards. In addition, historic cheetahs from all subspecies exhibited greater genetic diversity than modern Southern African cheetahs. Thus, indicating that cheetah have further lost diversity recently as a result of a population declines within the last 150 years. These results have identified that Southern African cheetahs may not be able survive future infectious diseases.

New paper: Rapid deterioration in buried leather: archaeological implications

Published on by Gillian

This recent paper was the accumulation of work by Helga Halldorsdottir with TU Earth and Environment researchers, Gillian Taylor and Rhys Williams (now at Loyola Maryland University), involving some huge data sets and really novel results. The experiment set-up was amazing…

The research used non-destructive Fourier Transform Infrared Spectroscopy (FTIR)-Attenuated Total Reflectance (ATR) analysis to reveal fascinating insights into how leather decays over time. The research focused on vegetable-tanned and archaeological leather from the Roman site of Vindolanda, UK. By analysing leather at different stages—raw, tanned, buried, and archaeological—the study observed how burial in wet soil leads to rapid changes, particularly the breakdown of lipids, while collagen remains intact. The findings suggest that de-tanning occurs quickly in waterlogged conditions, making archaeological leather resemble untanned leather.

One of the most interesting takeaways is that modern unburied leather doesn’t provide an accurate comparison to ancient samples, but experimentally buried leather does. Although de-tanning happens soon after burial, vegetable-tanning still plays a role in long-term preservation. The research also hints that mineral components in the leather may influence its preservation. Overall, the study highlights the complexity of leather decay and opens up new possibilities for understanding how ancient materials survive over time.
