Detecting and attributing climate change effects on vegetation: Australia as a test case

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Establecimiento de pasto plumerito (Trichloris crinita Parodi) en el año de siembra

Semiárida, 2020
El bosque de algarrobo en Mendoza presenta una serie de estados estables de baja productividad con un alto grado de arbustización. En estas condiciones, el uso del rolo cortador como herramienta de control del arbustal mejora dichos ambientes. La siembra

Response of reptiles to weed-control and native plant restoration in an arid, grass-invaded landscape

Global Ecology and Conservation, 2020
Introduced grasses are a major threat to dryland ecosystems world-wide because of their ability to transform plant communities and change fire regimes. These structural and functional shifts are often assumed to impact wildlife but this has rarely been ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Unveiling Microbial Dynamics and Gene Expression in Legume–Buffel Grass Coculture Systems for Sustainable Agriculture

Agronomy
Legumes enhance pasture health and soil productivity by fixing atmospheric nitrogen and boosting soil microbiota. We investigated the effects of tropical pasture legumes, including butterfly pea (Clitoria ternatea), seca stylo (Stylosanthes scabra ...

Soil greenhouse gases emissions in a goat production system in the Brazilian semiarid region

Pesquisa Agropecuária Tropical, 2022
In the climate change scenario, studying greenhouse gases (GHG) emissions and measures of mitigation in the Caatinga biome are strategic and may provide a basis for mitigation plans.

Lose the plot: cost-effective survey of the Peak Range, central Queensland [PDF]

, 2013
The Peak Range (22˚ 28’ S; 147˚ 53’ E) is an archipelago of rocky peaks set in grassy basalt rolling-plains, east of Clermont in central Queensland. This report describes the flora and vegetation based on surveys of 26 peaks.

Spinifex, fire, and fate

Geographical Research, Volume 63, Issue 4, Page 685-696, November 2025.
Abstract Bushfires occur regularly in inland Australia because of the flammability of spinifex (Triodia species). Spinifex and fire are tied together by infertility: the plant is of limited palatability to consumers and accumulates into fuel. Spinifex regrows with cumulative rainfall, and fires recur every couple of decades.

Review of productivity decline in sown grass pastures [PDF]

, 2011
Productivity decline in sown grass pastures is widespread in northern Australia and reduces production by approximately 50%, a farm gate cost to industry of > $17B over the next 30 years. Buffel grass is the most widely established sown species (>75% of

Pedogenesis of a coastal climosequence and a volcanic ash‐influenced elevational transect of western Haleakalā, Maui

Soil Science Society of America Journal, Volume 89, Issue 5, September/October 2025.
Abstract The western slope of Haleakalā, Maui, demonstrates a wide range in soil development (eight mapped soil orders), thus providing a unique opportunity to investigate how climate and volcanic ash deposition influence soil development on basalt.
