Revisiting Theron’s hypothesis on the origin of fairy circles after four decades: Euphorbias are not the cause

BMC Ecology and Evolution, 2021
Background The Euphorbia hypothesis on the origin of fairy circles (FCs) in Namibia dates back to 1979. It proposes that the remains of decaying shrubs would induce an allelopathic interaction with the grasses and thereby cause bare-soil FCs.

Functional diversity buffers the effects of a pulse perturbation on the dynamics of tritrophic food webs

Ecology and Evolution, 2021
Biodiversity decline causes a loss of functional diversity, which threatens ecosystems through a dangerous feedback loop: This loss may hamper ecosystems’ ability to buffer environmental changes, leading to further biodiversity losses.

Complex Trophic Interactions in an Acidophilic Microbial Community

Microorganisms, 2022
Extreme habitats often harbor specific communities that differ substantially from non-extreme habitats. In many cases, these communities are characterized by archaea, bacteria and protists, whereas the number of species of metazoa and higher plants is ...

The Relative Effects of Climate Change and Phenological Change on Net Primary Productivity Vary with Grassland Types on the Tibetan Plateau

Remote Sensing, 2023
Quantifying the impact of climate change and vegetation phenology on ecosystem productivity in the alpine grasslands of the Tibetan Plateau (TP) is essential for assessing carbon balance dynamics at regional and global scales.

The role of biotic factors during plant establishment in novel communities assessed with an agent-based simulation model [PDF]

PeerJ, 2018
Background Establishment success of non-native species is not only influenced by environmental conditions, but also by interactions with local competitors and enemies.

Variable Fitness Response of Two Rotifer Species Exposed to Microplastics Particles: The Role of Food Quantity and Quality

Toxics, 2021
Plastic pollution is an increasing environmental problem, but a comprehensive understanding of its effect in the environment is still missing. The wide variety of size, shape, and polymer composition of plastics impedes an adequate risk assessment.

Assessing the toxicity of polystyrene beads and silica particles on the microconsumer Brachionus calyciflorus at different timescales

Frontiers in Environmental Science, 2022
Environmental pollution by microplastics has become a severe problem in terrestrial and aquatic ecosystems and, according to actual prognoses, problems will further increase in the future.

The double-edged sword of inducible defences: costs and benefits of maladaptive switching from the individual to the community level

Scientific Reports, 2022
Phenotypic plasticity can increase individual fitness when environmental conditions change over time. Inducible defences are a striking example, allowing species to react to fluctuating predation pressure by only expressing their costly defended ...
