© The Ecological Society of America www.frontiersinecology.org T is a crucial need to understand ecological water balances, both in the present and in the future. This balance is currently shifting, as economies rapidly develop and urbanization accelerates (Hubacek and Sun 2005). In the future, global climate change and the resulting uncertainties will only add to the urgency of finding accurat...

Evaluating the collective impact of small source inputs to larger rivers is a constant challenge in riverine biogeochemistry. In this study, we investigated the generation of dissolved organic matter (DOM) in a small oak woodland catchment in the foothills of northern California, the subsequent transformation in lignin biomarkers and chromophoric DOM (CDOM) parameters during transport through t...

Bulk precipitation, stemflow and throughfall were collected in a Canarian laurel forest (North Tenerife), and chemically analysed to determine the net below canopy fluxes. Annual negative fluxes were found for Hþ, NO3 , SO4 2 and Cl and annual positive fluxes for Ca2þ, Mg2þ, Kþ, Naþ, HCO3 , PO4 32 and DOC. Negative fluxes for most of these ions have been reported previously but this is the firs...

High N depositions of past decades brought changes to European forests including impacts on forest soil nutrition status. However, the ecosystem responses declining atmospheric inputs or moderate attracted only less attention so far. Our study investigated macronutrient (N, S, Ca2+, Mg2+, K+) pools and fluxes at conversion sites over 80 years old in Central Germany with beech (so-called “Green ...

A synthesis of the biogeochemistry of S was done during 34 yr (1964–1965 to 1997–1998) in reference and human-manipulated forest ecosystems of the Hubbard Brook Experimental Forest (HBEF), NH. There have been significant declines in concentration (−0.44 mol/liter-yr) and input (−5.44 mol/ha-yr) of SO4 2− in atmospheric bulk wet deposition, and in concentration (−0.64 mol/liter-yr) an d output (...

There is enormous global interest in forest restoration, with governments around the world making high profile and ambitious commitments (Fagan et al., 2020). Carbon sequestration an important driver of this policy interest, but it widely recognized that restoration needs to be considered as part a landscape approach which aims improve both ecological functioning livelihoods local people (Chazd...

scape and consider the stages during oak life history where fire could potentially be used as a tool to enhance oak regeneration. Finally, we provide some guidance for management considerations in the field. The Oak–Fire Hypothesis: Issues in Contemporary Forests The oak–fire hypothesis suggests that oak forests require periodic fire disturbances for their successful regeneration and conservati...
