The ghost of nestedness in ecological networks [PDF]
Nature Communications, 2013 Ecologists are fascinated by the prevalence of nestedness in biogeographic and community data, where it is thought to promote biodiversity in mutualistic systems. Traditionally, nestedness has been treated in a binary sense: species and their interactions are either present or absent, neglecting information on abundances and interaction frequencies ...

Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah. [PDF]
J Anim EcolFor the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

Patterns and drivers of Nothobranchius killifish diversity in lowland Tanzania
Ecology and Evolution, 2022 Temporary pools are seasonal wetland habitats with specifically adapted biota, including annual Nothobranchius killifishes that survive habitat desiccation as diapausing eggs encased in dry sediment.

Ecological Indicators, 2022 Although biodiversity has been shown to profoundly affect ecosystem function in forests, the processes which it impacts are limited understood. Various plant species with diverse sizes interact to form complex networks to complete resource use processes,

Ecology and Evolution, 2022 Nitrogen (N) deposition poses a serious threat to terrestrial biodiversity and alters plant and soil microbial community composition. Species turnover and nestedness reflect the underlying mechanisms of variations in community composition.

Global Ecology and Conservation, 2015 Metacommunity nestedness can be affected by both idiosyncratic species and species turnover, and diversity partitioning allows one to separate turnover and nested components within β-diversity. Thus, complimentary analysis of metacommunity nestedness and

The dynamics of nestedness predicts the evolution of industrial ecosystems. [PDF]
PLoS ONE, 2012 In economic systems, the mix of products that countries make or export has been shown to be a strong leading indicator of economic growth. Hence, methods to characterize and predict the structure of the network connecting countries to the products that ...

Temporal origin of nestedness in interaction networks
PNAS Nexus, 2023 Abstract Nestedness is a common property of communication, finance, trade, and ecological networks. In networks with high levels of nestedness, the link positions of low-degree nodes (those with few links) form nested subsets of the link positions of high-degree nodes (those with many links), leading to matrix representations with ...

Food Web Topology and Nested Keystone Species Complexes
Complexity, 2018 Important species may be in critically central network positions in ecological interaction networks. Beyond quantifying which one is the most central species in a food web, a multinode approach can identify the key sets of the most central n species as ...

Human Impacts and Climate Change Influence Nestedness and Modularity in Food-Web and Mutualistic Networks. [PDF]
PLoS ONE, 2016 Theoretical studies have indicated that nestedness and modularity-non-random structural patterns of ecological networks-influence the stability of ecosystems against perturbations; as such, climate change and human activity, as well as other sources of ...
