Null models for network data

open access: yesCoRR, 2012
The analysis of datasets taking the form of simple, undirected graphs continues to gain in importance across a variety of disciplines. Two choices of null model, the logistic-linear model and the implicit log-linear model, have come into common use for analyzing such network data, in part because each accounts for the heterogeneity of network node ...

A niche for null models in adaptive resource management [PDF]

open access: yesEcology and Evolution, 2022
AbstractAs global systems rapidly change, our collective ability to predict future ecological dynamics will become increasingly important for successful natural resource management. By merging stakeholder objectives with system uncertainty, and by adapting actions to changing systems and knowledge, adaptive resource management (ARM) provides a rigorous

Assembly Processes and Co-occurrence Patterns of Abundant and Rare Bacterial Community in the Eastern Indian Ocean

open access: yesFrontiers in Microbiology, 2021
Microbial communities are composed of many rare species and a few abundant species. Considering the disproportionate importance of rare species for ecosystem functioning, it is important to understand the mechanisms structuring the rare and abundant ...

Measuring nestedness: A comparative study of the performance of different metrics

open access: yesEcology and Evolution, 2020
Nestedness is a property of interaction networks widely observed in natural mutualistic communities, among other systems. A perfectly nested network is characterized by the peculiarity that the interactions of any node form a subset of the interactions ...

Environmental filtering and dispersal limitation jointly shaped the taxonomic and phylogenetic beta diversity of natural forests in southern China

open access: yesEcology and Evolution, 2021
Aim The mechanisms underlying the maintenance of biodiversity remain to be elucidated. Taxonomic diversity alone remains an unresolved issue, especially in terms of the mechanisms of species co‐existence.

Assessing information-sharing networks within small-scale fisheries and the implications for conservation interventions

open access: yesRoyal Society Open Science, 2021
The effectiveness of behavioural interventions in conservation often depends on local resource users' underlying social interactions. However, it remains unclear to what extent differences in related topics of information shared between resource users ...

Comparing spatial null models for brain maps [PDF]

open access: yesNeuroImage, 2020
Technological and data sharing advances have led to a proliferation of high-resolution structural and functional maps of the brain. Modern neuroimaging research increasingly depends on identifying correspondences between the topographies of these maps; however, most standard methods for statistical inference fail to account for their spatial properties.

Deterministic processes dominate archaeal community assembly from the Pearl River to the northern South China Sea

open access: yesFrontiers in Microbiology, 2023
Archaea play a significant role in the biogeochemical cycling of nutrients in estuaries. However, comprehensive researches about their assembly processes remain notably insufficient.

Evidence for the Vacated Niche Hypothesis in Parasites of Invasive Mammals

open access: yesEcology and Evolution
Species redistribution and invasion are becoming increasingly common due to climate change and anthropogenic impacts. Understanding the resultant shifts in host–parasite associations is important for anticipating disruptions to host communities, disease ...
