Drastic peatland regime shift and landscape disturbances connected to warm and cold climate events over the past centuries in subarctic Finland

open access: yesBoreas, EarlyView.
Palaeoecological studies reporting long‐term development histories of subarctic fens—explicitly, orohemiarctic peatlands—are scarce, and overall, permafrost‐free peatlands located in the immediate vicinity of permafrost zones have received little attention in Fennoscandia. Here, we use a multiproxy approach to study the millennial‐scale dynamics of two

Food web reconstruction of Barmaky, the oldest post‐LGM hunter‐gatherer site in north‐western Ukraine

open access: yesBoreas, EarlyView.
The site of Barmaky currently marks the oldest Epigravettian occupation of north‐western Ukraine shortly after the Last Glacial Maximum (LGM), dated to around 19 cal. ka BP. Stable isotope analyses of bone collagen from six terrestrial mammals and two bird species show a comparatively highly structured palaeo‐food web.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

open access: yesBoreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Using incentive payments to promote human–carnivore coexistence

open access: yesConservation Biology, EarlyView.
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

Environmental factors affect the condition of critically endangered freshwater pearl mussels by disrupting terrestrial–aquatic resource connectivity

open access: yesConservation Science and Practice, EarlyView.
This regional‐scale field study shows that critically threatened freshwater pearl mussels rely substantially on terrestrial organic matter, indicating strong connectivity between terrestrial and aquatic ecosystems. However, human pressures at the catchment scale reduced this resource connectivity.

Hydrogeochemistry of the Caribou-Poker Creeks Research Watershed [PDF]

open access: yes, 1982
Bedrock of the Caribou-Poker Creeks Research Watershed dissolves incongruently with a first-order rate constant of about 5 x 10-6 day-1 at 5° C. The resulting solution is potassium-calcium-magnesium rich.

Bake Sales to Save Nature: Why Wall Street Conservation Survives

open access: yesDevelopment and Change, EarlyView.
ABSTRACT Academics have spent decades analysing the harms and failures of market and finance‐led biodiversity policy. Yet, even though ‘selling nature to save it’ looks less like the promised green capitalism and more like a decades‐long bake sale in that its efforts are small, piecemeal and rely on copious amounts of cheap capital, the approach ...
