A Risk-Based Method For Estimating The Carbon Sequestration Budget For a Mixed Hardwood Forest [PDF]

open access: yes, 2017
Carbon Dioxide (CO2) levels in the atmosphere have risen from approximately 310 ppm in the 1950’s to over 400 ppm as of 2015. This rise in CO2 has likely resulted in the observed warming trend of the earth’s atmosphere in the same time frame, causing ...

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

open access: yesEthology, EarlyView.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.

Molecular evidence for sediment nitrogen fixation in a temperate New England estuary [PDF]

open access: yes, 2016
Primary production in coastal waters is generally nitrogen (N) limited with denitrification outpacing nitrogen fixation (N2-fixation). However, recent work suggests that we have potentially underestimated the importance of heterotrophic sediment N2 ...

Shaping future forests: how can ecophysiology support climate‐smart forest management?

open access: yesNew Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Open-loop payment preferences in public transit: Exploring alternatives to cash for unbanked riders

open access: yesTransportation Research Interdisciplinary Perspectives
Transit providers in the US and abroad are adopting open-loop payments; these systems accept credit and debit cards as well as other digital forms of payment at boarding or fare gates and do not require an agency-specific card or app.

Turgor loss point explains climate‐driven growth reductions in trees in Central Europe

open access: yesPlant Biology, EarlyView.
Leaf turgor loss point of native tree species shows a high predictive power over the observed growth anomalies in Central Europe during the extensive drought period between 2018 and 2020. Abstract As climate change thrives, and the frequency of intense droughts is affecting many forested regions, a mechanistic understanding of the factors conferring ...

Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest

open access: yesPlant Biology, EarlyView.
A series of hot drought events caused persistent legacy effects in a Scots Pine forest, with severe negative impacts on ecosystem carbon fluxes. Abstract Recent hot‐dry events have caused significant impacts and legacy effects in temperate ecosystems. Here, we investigate legacy effects of the 2018 hot drought on a Pinus sylvestris L.
