Increasing Respiration Weakens the Carbon Sink Over Two Decades in a Temperate Deciduous Forest

ABSTRACT Temperate deciduous forests have been major carbon sinks over the past century, largely due to regrowth following historical land use. However, the persistence of this sink is uncertain as forests age under global change. Using two decades (2004–2023) of eddy covariance...

Selection in the City: The Supply of Trees to Baltimore’s Urban Forest

Domestic selection creates the assemblages of organisms found in human-dominated environments, and urban forestry is a useful illustration of this process in action. In this study, we aim to understand how the process of domestic selection influences the nursery supply chain of t...

Stable isotopes as integrators of soil biogeochemistry and tree growth across contrasting hardwood forest soils

Abstract Background & aims Forest productivity and resilience are influenced by soil conditions; however, the mechanisms linking soil properties, isotopic signatures, and tree growth remain incompletely understood. This study evaluated whether soil carbon (δ 13 C) and nitroge...
