Late Holocene moisture variability in Arctic Alaska from chitin δ18O

Boreas, EarlyView.
Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019

Conservation Biology, EarlyView.
Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.

Precipitation fuels dissolved greenhouse gas (CO2, CH4, N2O) dynamics in a peatland-dominated headwater stream: results from a continuous monitoring setup

Frontiers in Water
Stream ecosystems are actively involved in the biogeochemical cycling of carbon (C) and nitrogen (N) from terrestrial and aquatic sources. Streams hydrologically connected to peatland soils are suggested to receive significant quantities of particulate ...

Priority areas for arthropod conservation in the Iberian Peninsula and Balearic Islands: Insights from a multi‐taxon distributional database

Insect Conservation and Diversity, EarlyView.
Using over 416,000 occurrence records from 13 arthropod groups (6233 arthropod species), we mapped large‐scale richness patterns and identified biodiversity hotspots across the Iberian Peninsula and Balearic Islands. Hotspot congruence among arthropod groups was low, underscoring the importance of integrative, multi‐taxon approaches for conservation ...

Urban peatlands can harbour diverse insect communities but depend on appropriate habitat management

Insect Conservation and Diversity, EarlyView.
Urban peatlands can support high insect diversity, including endangered species and peat bog specialists. Flower diversity boosts endangered species, while succession cover reduces overall insect richness—but bog condition and urbanization showed no major effects.

Remaking State Power Through a Paraquat Ban in Malaysia

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper examines the role of the state in its ability to enact environmental regulations. Specifically, this study investigates how Malaysian state actors changed, shifted and betrayed various, oftentimes competing interests to ban paraquat, an acutely toxic herbicide.

Fine-Scale Plant Species Identification in a Poor Fen and Integration of Techniques and Instrumentation in a Classroom Setting [PDF]

, 2015
Refining carbon flux measurements in the carbon cycle is an ongoing challenge. This study attempted to identify plant species in Sallie’s Fen, a nutrient-poor fen in Barrington, New Hampshire, at a fine scale in order to better model and understand ...

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, EarlyView.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.
