Can fish species co-occurrence patterns be predicted by their trait dissimilarities?
Royal Society Open Science, 2023 Trait-based analyses have been successful in determining and predicting species association outcomes in diverse communities. Most studies have limited the scope of this approach to the biotic responses of a small number of species or geographical regions.

Frontiers in Marine Science, 2021 Community assembly is the result of both, deterministic and stochastic processes. The former encompasses niche-based local-scale mechanisms such as environmental filtering and biotic interactions; the latter includes ecological drift, probabilistic ...

Null models for understand intertidal decapods communities in North Patagonian beach (Pelluhuin, 41°S, Chile) [PDF]
Brazilian Journal of BiologyThe intertidal decapods in continental Chile are characterized by its species sharing with Peruvian coast along practically all coast, being coexisting species that has not studied with details its interspecific interactions. The aim of the present study

A simple null model predicts the island rule [PDF]
Ecology Letters, 2021 Abstract The island rule is a putative pattern in island evolution, where small species become larger on islands and large species become smaller. Despite decades of study, a mechanistic explanation for why some taxonomic groups obey the island rule, while others do not, has yet to be identified.

Brazilian Journal of Biology, 2007 The main factors that structure Neotropical animal communities have been the subject of discussion in ecology communities. We used a set of null models to investigate the existence of structure in snake communities from the Cerrado in Central Brazil in ...

Inferring monopartite projections of bipartite networks: an entropy-based approach
New Journal of Physics, 2017 Bipartite networks are currently regarded as providing a major insight into the organization of many real-world systems, unveiling the mechanisms driving the interactions occurring between distinct groups of nodes.

CoRR, 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 ...

Methods in Ecology and Evolution, 2022 Ecological networks such as plant–pollinator systems and food webs vary in space and time. This variability includes fluctuations in global properties such as the total number and intensity of interactions in the network but also in the number and ...

A null model for Pearson coexpression networks
PLOS ONE, 2013 Abstract Gene coexpression networks inferred by correlation from high-throughput profiling such as microarray data represent a simple but effective technique for discovering and interpreting linear gene relationships. In the last years several approach have been proposed to tackle the problem of deciding when the resulting correlation ...
