The influence of soil communities on the temperature sensitivity of soil respiration [PDF]

, 2018
Soil respiration represents a major carbon flux between terrestrial ecosystems and the atmosphere, and is expected to accelerate under climate warming.

neonSoilFlux: An R package for continuous sensor‐based estimation of soil CO2 fluxes

Methods in Ecology and Evolution, EarlyView.
Abstract Accurate quantification of soil carbon fluxes is essential to reduce uncertainty in estimates of the terrestrial carbon sink. However, these fluxes vary over time and across ecosystem types and so, it can be difficult to estimate them accurately across large scales.

Detailed temporal modelling of carbon and water fluxes from pastures in New Zealand : case study of an experimental dairy farm in the Waikato region : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Soil Science, Massey University, Palmerston North, New Zealand [PDF]

, 2017
The terrestrial biosphere is an important pool of carbon, with its size governed by the opposing processes of CO2 uptake through photosynthesis and release through respiration.

Transient simulations of the carbon and nitrogen dynamics in northern peatlands: from the Last Glacial Maximum to the 21st century [PDF]

, 2012
The development of northern high-latitude peatlands played an important role in the carbon (C) balance of the land biosphere since the Last Glacial Maximum (LGM).

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

What controls forest litter decomposition? A coordinated distributed teabag experiment across ten mountains

Ecography, EarlyView.
Litter decomposition in mountainous forest ecosystems is an essential process that affects carbon and nutrient cycling. However, the contribution of litter decomposition to terrestrial ecosystems is difficult to estimate accurately because of the limited comparability of different studies and limited data on local microclimatic and non‐climatic factors.

Various responses of global heterotrophic respiration to variations in soil moisture and temperature enhance the positive feedback on atmospheric warming

Communications Earth & Environment
The ratio of soil heterotrophic respiration to total soil respiration (Rh/Rs) is critical for soil carbon pool stability and atmosphere-biosphere exchanges, yet its spatiotemporal dynamics and responses to environmental drivers remain poorly constrained.

Modelling carbon stock and carbon sequestration ecosystem services for policy design: a comprehensive approach using a dynamic vegetation model

Ecosystems and People, 2019
Ecosystem service (ES) models can only inform policy design adequately if they incorporate ecological processes. We used the Lund-Potsdam-Jena managed Land (LPJmL) model, to address following questions for Mexico, Bolivia and Brazilian Amazon: (i) How ...
