Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed. Further, these thres...

Natural methane emissions feedbacks in MAGICC v. 7.6

Literature estimates of natural methane emissions, particularly from wetlands, have a wide range of uncertainty. Meanwhile, few Earth System Models (ESMs) explicitly model wetlands as a potential source of methane. As a result, Simple Climate Models that aim to emulate the behavi...

Past rapid spread of introduced livestock coincided with vegetation clearance on Madagascar

Debates persist around the past and present effects of introduced livestock on the native biodiversity of Madagascar. Indeed, the variable habitat and past rate of spread of livestock across the island's distinct ecoregions are poorly known. Sets of 14C and stable isotope data fr...

DirPA: Addressing prior shift in imbalanced few-shot crop-type classification

Real-world agricultural monitoring is often hampered by severe class imbalance and high label acquisition costs, resulting in significant data scarcity. In few-shot learning (FSL) —a framework specifically designed for data-scarce settings—, training sets are often artificially b...

A general physiologically driven representation of leaf turnover in grasslands in the QUINCY land surface model (revision: 974a6b7f)

Abstract. Terrestrial vegetation plays an important role in shaping the Earth's climate due to its control on the global carbon cycle. Understanding and predicting vegetation phenology and biomass turnover into soil organic matter is therefore of great importance for our understa...

A global dataset of forest disturbance regimes derived from satellite biomass observations

Abstract. Forests play a central role in the global carbon cycle by serving as critical carbon sinks for atmospheric CO2. Yet, the stability and continued capacity of these sinks are increasingly threatened by a growing number of disturbances. Accurately representing the stochast...
