One Hundred Years of the German Soil Science Society (DBG) 1926–2026: Origins, Facts, and Background of an Eventful History

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...

Spatial and Temporal Ecological Uniqueness of Andean Diatom Communities Are Correlated With Climate, Geodiversity and Long-Term Limnological Change

open access: yesFrontiers in Ecology and Evolution, 2020
High-elevation tropical lakes are excellent sentinels of global change impacts, such as climate warming, land-use change, and atmospheric deposition. These effects are often correlated with temporal and spatial beta diversity patterns, with some local ...

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 ...

Forest or tundra? How different vegetation reconstructions of Last Glacial landscapes in Europe may shape our perception of early human dispersal processes

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Regional variability and long‐term changes of past ecosystems likely had a strong impact on hunter–gatherer population dynamics, including the expansion of anatomically modern humans and the disappearance of Neanderthals. However, our understanding of these ecosystems remains limited, even when looking at large‐scale patterns, such as the ...

Mapping major types of hunting across the South American Dry Chaco and Chiquitano forests

open access: yesPeople and Nature, EarlyView.
Abstract Hunting is a central, culturally embedded relationship between people and nature, yet also drives wildlife declines with far‐reaching consequences for ecosystems and people. It is also a highly diverse practice, involving a wide range of actors and hunting techniques, both of which determine the social‐ecological impacts of hunting.

Flowering phenology of herbarium specimens reveals century‐scale shifts in allergenic pollen seasonality

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Pollen allergies are a primary cause of seasonal allergic rhinitis, which affects over 500 million people globally, damaging quality of life and incurring significant costs in medical treatment and reduced work productivity. Many countries monitor pollen to inform allergy sufferers about seasonal pollen levels.

Vulnerability to Dams of the Last Undammed Large Rivers of Southeast Asia

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The vast majority of large Eurasian rivers are regulated by hydropower dams, but some have survived as free‐flowing rivers so far in the Arctic and along stretches of the Myanmar coast. There, the Ayeyarwady (Irrawaddy) and Salween Rivers, two of the largest rivers of Southeast Asia, provide a huge amount of sediment, nurturing floodplains and
