Net primary productivity, allocation pattern and carbon use efficiency in an apple orchard assessed by integrating eddy covariance, biometric and continuous soil chamber measurements [PDF]

open access: yesBiogeosciences, 2013
Carbon use efficiency (CUE), the ratio of net primary production (NPP) over gross primary production (GPP), is a functional parameter that could possibly link the current increasingly accurate global GPP estimates with those of net ecosystem exchange ...

Spatial distribution of regional whole tree carbon stocks and fluxes of forests in Europe [PDF]

open access: yes, 2001
This report presents carbon stocks and fluxes of the whole-tree biomass of European forests and other wooded land, distinguished into coniferous, deciduous and mixed forests. The results are presented at the European, the national and (where possible)the

Variability in the Net Ecosystem Productivity (NEP) of Seaweed Farms

open access: yesFrontiers in Marine Science, 2022
The important role of vegetated ecosystems in the sequestration of carbon has gained strong interest across a wide variety of disciplines. With evidence growing of the potential for macroalgae ecosystems to capture carbon, there is burgeoning interest in applying newfound knowledge of carbon capture rates to better understand the potential for carbon ...

Understanding bio‐based polymers: A study of origins, properties, biodegradation and their impact on health and the environment

open access: yesFEBS Open Bio, EarlyView.
This review provides an overview of bio‐based polymer sources, their unique functional properties and their environmental impact, and addresses their role as sustainable alternatives. It discusses end‐of‐life options, including composting and anaerobic digestion for renewable energy.

Forest Stand Structure and Primary Production in relation to Ecosystem Development, Disturbance, and Canopy Composition [PDF]

open access: yes, 2016
Temperate forests are complex ecosystems that sequester carbon (C) in biomass. C storage is related to ecosystem-scale forest structure, changing over succession, disturbance, and with community composition.

Comparison of ecosystem processes in a woodland and prairie pond with different hydroperiods [PDF]

open access: yes, 2017
Shallow lakes and ponds constitute a significant number of water bodies worldwide. Many are heterotrophic, indicating that they are likely net contributors to global carbon cycling. Climate change is likely to have important impacts on these waterbodies.

Enabling Digital Continuity in Virtual Manufacturing for Eco‐Efficiency Assessment of Lightweight Structures by Means of a Domain‐Specific Structural Mechanics Language: Requirements, Idea and Proof of Concept

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Spatiotemporal variation in the sign and magnitude of ecosystem engineer effects on lake ecosystem production

open access: yesEcosphere, 2019
Ecosystem engineers can have diverse and conflicting effects on their ecosystems, and the balance between these effects can depend on the physical environment.

Ecosystem overfishing in the ocean. [PDF]

open access: yesPLoS ONE, 2008
Fisheries catches represent a net export of mass and energy that can no longer be used by trophic levels higher than those fished. Thus, exploitation implies a depletion of secondary production of higher trophic levels (here the production of mass and ...
