Oikos, EarlyView.Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

Multitrophic alpha and beta diversity of lake plankton across Canada
Oikos, EarlyView.Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin
Oikos, EarlyView.Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Trapped in the web: network architectures spread coevolution and shape adaptation
Oikos, EarlyView.Adaptation is critical for biodiversity to persist under global change. Within ecological communities, species often face tradeoffs between adapting to shifting abiotic conditions and navigating the complex selective pressures imposed by interaction networks.

Constructing composite indicators with Shannon entropy: The case of Human Development Index
Socio-Economic Planning Sciences, 2020In this paper, we propose a weighting scheme for constructing composite indicators based on Shannon entropy. Its main advantages are that it delivers a set of common weights across decision-making units that allow for complete comparison and ranking and ...

Integrated flood vulnerability assessment approach based on TOPSIS and Shannon entropy methods
Ecological Indicators, 2018Flood vulnerability assessment is becoming increasingly important around the world. Nevertheless, the high-dimensional and non-linear relationship between various indices and flood vulnerability greatly hinders researchers from making a reasonable ...

Redistributing algorithms and Shannon’s Entropy
Aequationes mathematicae, 2022Shannon's entropy is one of the most popular measures of disorder. Together with the concept of permutation entropy, they are used to quantify the uncertainty and disorder of a time series. This is based on the appearance of ordinal patterns. There are several approaches to calculate the tuples rearrangement of the components with the ups and downs ...
