Modeling Institutions in Socio-Ecosystems [PDF]

Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence, 2021
In socio-ecosystems, human activities are structured in time and space by interactions between different regulatory systems with different collective goals. These regulatory systems are modeled by institutions and organizations, and the regulatory mechanisms by norms applied to agents in Multi-Agent Systems (MAS).

Effects of Short-Term Nitrogen Addition on Soil Fungal Community Increase with Nitrogen Addition Rate in an Alpine Steppe at the Source of Brahmaputra

Microorganisms, 2023
The soil fungal community plays a crucial role in terrestrial decomposition and biogeochemical cycles. However, the responses of the soil fungal community to short-term nitrogen addition and its related dominant drivers still remain unclear.

Observational Verification of the Cumulative Resilience Screening Index (CRSI) Using Hurricanes, Inland Floods, and Wildfires From 2016 to 2019

GeoHealth, 2022
Users can apply three processes to develop confidence in decision‐making tools like models and indices—validation, verification, and observation. The utility of the Cumulative Resilience Screening Index (CRSI) was demonstrated by combining the processes ...

Propagule pressure and an invasion syndrome determine invasion success in a plant community model

Ecology and Evolution, 2021
The success of species invasions depends on multiple factors, including propagule pressure, disturbance, productivity, and the traits of native and non‐native species.

The empirical modeling of an ecosystem [PDF]

Ecological Modelling, 1978
Abstract The authors have endeavored to create a verified a-posteriori model of a planktonic ecosystem. Verification of an empirically derived set of first-order, quadratic differential equations proved elusive due to the sensitivity of the model system to changes in initial conditions. Efforts to verify a similarly derived set of linear differential

Has the Dominant Climatic Driver for the Carbon Budget of Alpine Grassland Shifted from Temperature to Precipitation on the Qinghai–Tibet Plateau?

Remote Sensing, 2023
The alpine grassland on the Qinghai–Tibet Plateau (AGQTP) has undergone severe climate change. Although the carbon budget of AGQTP proved to have altered significantly, the spatiotemporal dynamics and the driving mechanism of the changes remain debated ...

Biogenic Aggregation of Small Microplastics Alters Their Ingestion by a Common Freshwater Micro-Invertebrate

Frontiers in Environmental Science, 2020
In recent years, increasing concerns have been raised about the environmental risk of microplastics in freshwater ecosystems. Small microplastics enter the water either directly or accumulate through disintegration of larger plastic particles.

Effects of climate change and anthropogenic activities on soil pH in grassland regions on the Tibetan Plateau

Global Ecology and Conservation, 2023
Although soil pH is an important indicator of soil quality, the effects of climate change and anthropogenic activities on soil pH remain controversial.

Different responses of soil bacterial species diversity and phylogenetic diversity to short-term nitrogen input in an alpine steppe at the source of Brahmaputra

Frontiers in Ecology and Evolution, 2022
The Qinghai-Tibet Plateau has experienced an increase in N deposition/input due to global change. However, it remains unclear how the responses and whether the responses of soil bacterial diversity to short-term N input are consistent at different levels.
