Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

open access: yesJournal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Small Community Businesses in Slums: A Perspective on Kenyan Slum Networks

open access: yesStrategic Change, EarlyView.
ABSTRACT Despite extensive research on networks, the relational dimensions and structures cocreated by small community businesses and cooperative societies through everyday entrepreneurship in slum neighborhoods remain undertheorized. Drawing upon 1166 small community businesses, we conceptualize the relational dimensions and structures underlying ...

Cross‐regional and temporal generalizability of portable visible spectroscopy for olive maturity classification

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Olive maturity governs lot destination and the yield–quality trade‐off in olive oil production, yet it is still monitored by subjective visual scoring of the Jaén index. Spectroscopic alternatives have relied mainly on near‐infrared instruments, with scarce evidence from Brazilian orchards and almost no evaluation of spatial or ...
