Mathematics, Physics, and Computer Science Faculty Articles and Research

As climate change intensifies, extreme weather increasingly threatens California’s Central Valley (CV), a vital agricultural region exposed to rising risks from heatwaves (HW), droughts (DR), and compound extremes. These events disrupt crop productivity and broader processes like water demand, pest dynamics, and soil stability, posing systemic risks. This study examines the spatiotemporal dynamics of HW, coldwaves (CW), DR, excessive rainfall (ER), and their compound (e.g., HWDR) and cascading forms from 1951 to 2025, using NOAA nClimGrid-Daily data. We assessed trends in frequency, intensity, and duration over long-term (1951–2025) and mid-term (1981–2025) periods. Results show increasing HW and DR in the …

Microclimatic Conditions In Shulgan-Tash Cave (Southern Ural, Russia): Implications For The Preservation Of Eastern Europe’S Largest Paleolithic Art Collection, Olga Chervyatsova, Rayan Akhmedyanovb, Nailya Saifullina, Ludmila Kuzmina, Mihael Kotov, Yuri Dublyansky

International Journal of Speleology

This study presents the results of a long-term investigation of the microclimatic conditions in Shulgan-Tash Cave (Southern Urals, Russia), which hosts the largest assemblage of Upper Paleolithic paintings (ca. 16.3–19.6 ka) in Eastern Europe. The cave exhibits two distinct seasonal ventilation regimes – winter and summer – differentially influence its two levels of galleries. In the Lower Level, which contains 83% of the images, near-atmospheric CO₂ concentrations persist year-round, and temperature variations associated with seasonal infiltration events are minimal (1.0–1.3°C). By contrast, the Upper Level, including the decorated Hall of Paintings, is affected by downdrafts of CO₂-rich …

Tillage Legacy, Grasses And Soil Texture Shape Soil Organic Carbon Recovery In Semi-Arid Woodland, Samantha Colunga, Alejandro Fierro-Cabo, Bradley O. Christoffersen, Engil Pereira

School of Earth, Environmental, & Marine Sciences Faculty Publications

Soil degradation from intensive tillage poses a critical barrier to carbon sequestration, particularly in semi-arid regions where low rainfall limits ecosystem recovery. As climate change expands arid zones globally, understanding the long-term potential for soil organic carbon (SOC) recovery in degraded lands becomes increasingly urgent. Here, we analyze reforested chronosequences (4–36 years post-abandonment) in formerly cultivated subtropical thornscrub woodlands to assess SOC dynamics across gradients of soil texture and degradation. We introduce a novel degradation index (DI), integrating SOC deficit and grass dominance, to evaluate how invasive grasses, commonly overlooked in restoration metrics, impede nitrogen (N2)-fixing tree establishment and, consequently, …

Fisheries Research Report No. 354: Recreational Fishing For Abalone In Western Australia In 2024/2025 - Estimates Of Participation, Effort And Catch, Claire B. Smallwood, Karina L. Ryan, Lachlan W. Strain

Fisheries Research Reports

The Western Australian Recreational Abalone Fishery (RAF) operates in shallow coastal waters as a hand collection fishery while wading or diving. Three species of abalone are allowed to be caught. Roe’s abalone (Haliotis roei) are generally collected while wading from the shore in accessible nearshore reef complexes along the West and South Coast Bioregions. Greenlip abalone (H. laevigata) and Brownlip abalone (H. conicopora) are collected while wading (including snorkelling and freediving) and diving (using compressed air) predominantly along the South Coast Bioregion.

Recreational fishing for the three abalone species is licensed and highly regulated, especially in the Western Zone (which …

Carbon Footprint Of Carrots In Western Australia, Christophe D'Abbadie, Saloomeh Akbari, Sang Ravindran

Horticulture research reports

This report presents the findings of a comprehensive carbon accounting study conducted on carrot production in the Myalup area of Western Australia.

The study reveals that carrot emissions are approximately 81 kg CO2e per tonne of carrot sold from the April harvest and 76 kg CO2e per tonne from the October harvest, when using rejected carrots for other economic uses. These figures represent competitive emissions intensities compared to international benchmarks.

Key findings include:

• Yield improvement is the primary driver for emissions reduction: Increasing productivity, without proportional input increases, offers the most effective pathway to lower emissions’ intensity while improving economic …

Evolution Of Agricultural Emissions Calculations In Australia: Methodological And Calculator Refinements And Their Impact On Western Australia’S Agricultural Carbon Footprint, Christophe D'Abbadie

Climate Science Published Reports

Greenhouse gas (GHG) emissions accounting is fundamental to positioning Australian agricultural products competitively in global markets, enabling supply chain stakeholders to make informed decisions, and understanding the trade-offs between market demands, policy requirements, consumer expectations, and intergenerational responsibilities.

Recent methodological refinements to emissions methodologies have enhanced the accuracy of GHG accounting in Western Australian (WA) agriculture. The Department of Primary Industries and Regional Development (DPIRD) has collaborated in these improvements through collaborative research with universities and federal agencies and advocacy for Western Australia-specific emission factors.

Methodological refinements have improved the accuracy of WA agricultural emissions estimates by 6% overall, providing …

Assessing Expected Cover Of Invasive Flora Species Near Corridor Features By Distance, Joshua G. Logan

Theses

Fragmentation of landscapes has been a growing topic of interest within scientific literature over the past several decades, as the way we as humans affect our planet becomes more apparent as the years go on. As humans, we have shaped the land and what it contains in immeasurable ways, erasing or forever altering entire natural ecosystems. Chief among the drivers altering these ecosystems is the fragmentation of landscapes, which can have all kinds of effects on natural ecosystems, from limiting nutrient transport to providing easier access for invasives to permeate throughout a landscape. Corridors are significant areas of interest regarding …

A Feature Engineering Technique For Enhancing The Generalization Of Machine Learning Models In Estimating Crop Evapotranspiration, Gaku Yokoyama, Sohta Harigai, Shigehiro Kubota, Koichi Nomura, Gregory R. Goldsmith, Daisuke Yasutake, Tomoyoshi Hirota, Masaharu Kitano

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Accurate and precise estimation of evapotranspiration (ET) is crucial for understanding the terrestrial carbon, water, and energy cycles. While process-based models of ET, such as the Penman–Monteith model offer robust generalization capabilities, they are limited by the need for detailed parameters (e.g., stomatal conductance,) that are challenging to measure continuously. On the other hand, machine learning models can estimate ET by capturing relationships between ET and environmental variables without experimentally measuring model parameters. However, machine learning models face the challenge of limited generalizability. This issue is particularly significant given the uncertainty introduced by changing climatic …
