ATMOSPHERIC RADIOCARBON FOR THE PERIOD 1950-2019

Quan Hua et al.

Summary: This paper presents a compilation of atmospheric radiocarbon for the period 1950-2019, including zonal, hemispheric, and global radiocarbon datasets, with smooth curves more suitable for dating applications, aiming to facilitate the use of atmospheric bomb C-14 in carbon cycle studies and meet the increasing demand for accurate dating of recent terrestrial samples.

The loss of an indigenous constructed landscape following British invasion of Australia: An insight into the deep human imprint on the Australian landscape

Michael-Shawn Fletcher et al.

Summary: The study demonstrates how the Australian landscape was heavily influenced by Indigenous land management practices prior to British invasion in the 18th century, and how the disruption of these practices led to ecological succession and encroachment of cool temperate rainforest into important grasslands. It challenges the traditional portrayal of Indigenous Australians as low-impact 'hunter-gatherers' and emphasizes the importance of Indigenous fire management in the face of increased bushfire risk and biodiversity loss.

Foraging by an avian ecosystem engineer extensively modifies the litter and soil layer in forest ecosystems

Alex C. Maisey et al.

Summary: The Superb Lyrebird is proposed as an ecosystem engineer in southeastern Australian forests due to its significant impact on soil and litter turnover. Research shows that Lyrebirds' foraging behavior influences ground cover and soil nutrients, leading to profound effects on forest ecosystems.
