SummaryThere has been dispute whether patterns of species co-occurrence on islands are largely random. We present a new method for testing this question; this method lets one not only examine whether a whole fauna is non-randomly structured, but also identify in which direction and by how much each particular species combination deviates from expectations based on randomness. Application of this method to the whole Bismarck and New Hebridean avifaunas, and to two particular guilds, shows that… Expand

Methods for detecting non-randomness in species co-occurrences: a contribution
SummaryComparison of co-occurrences between species on a group of islands with those expected from a randombased null model could provide evidence on community structure. However, it is difficult toExpand
Species co-occurrences and neutral models : reassessing
The question whether species co-occurrence patterns are non-random has intrigued ecology for more than two decades. Recently Gotelli and McCabe used meta-analysis to show that natural assemblagesExpand
Investigating species co-occurrence patterns when species are detected imperfectly
TLDR
A statistical method for modelling co-occurrence patterns between species while accounting for imperfect detection and site characteristics is presented and some evidence of a statistical interaction between species in terms of detectability is found that may be due to changes in relative abundances.

Pairwise co-existence of Bismarck and Solomon landbird species
TLDR
In each archipelago, proportionately more congeneric species pairs than noncongeneric species pairs are unusually negative pairs; this holds even for species pairs that overlap in their incidences. Expand
Competitive exclusion, or species aggregation?
TLDR
It is shown that extreme checkerboardedness can be produced by forces making for species aggregation, just as well as by those making for avoidance, and that competition pressures, if they exist, are overcome by countervailing factors. Expand
Species co-occurrences and neutral models: reassessing J. M. Diamond's assembly rules
TLDR
It is shown that neutral ecological drift models are able to generate patterns in line with Diamond's assembly rules and very similar to the empirical results in Gotelli and McCabe. Expand
Examination of the “null” model of connor and simberloff for species co-occurrences on Islands
TLDR
It is found that three faunas tested have grossly non-random structures, while their test is unworkable for the fourth fauna, and the value of constructing null hypotheses in community ecology is examined. Expand
THE CO‐DISTRIBUTION OF SPECIES IN RELATION TO THE NEUTRAL THEORY OF COMMUNITY ECOLOGY
TLDR
Two systematic surveys of plant communities do indeed show stronger associations than are expected in randomly assembled communities, but neutral community models, however, also predict nonrandom patterns of co-distribution. Expand
Niche dissociated assembly drives insular lizard community organization
TLDR
The empirical data on insular lizard community on species co-occurrence, SADs, and body size ratios does not lend support to assortment of species in islands caused by niche subdivision, indicating that niche-dissociated assembly ofspecies in islands might be an important factor in formation of biological communities, regardless of geographic scale.

A probabilistic model for analysing species co-occurrence
Aim To develop a new probabilistic model that can be used to test for statistically significant pair-wise patterns of species co-occurrence. The model gives the probability that two species wouldExpand

Using Island Biogeographic Distributions to Determine if Colonization is Stochastic
TLDR
A number of models for the process of island colonization have been proposed in the literature, but analysis to date has not been sufficiently profound that one must discard Occam's razor and seek different explanations for the distributions of different taxa. Expand

TLDR
The consistency of the patterns and variation within component species is highly compatible to explanations invoking competition and complements previously described population and community characteristics of West Indian birds. Expand

TLDR
Interarchipelagal differences in nu(i) or average nu reflect differences in level of interspecific competition, which reduces nus in species-rich archipelagoes in two ways: usually, by reducing a species' incidence on small islands and restricting the species to larger islands; less often (for so-called supertramps), by restricting a species to small islands.

Species Interactions and Community Structure in Alaskan Seabird Colonies
TLDR
This work quantifies species associations and community structure within five nesting guilds of Alaskan seabirds using multiway contingency tables and log-linear models and finds that higher order interactions, although uncommon, may suggest a type of diffuse competition. Expand

Species Number and Compositional Similarity of the Galapagos Flora and Avifauna
TLDR
The flora and avifauna of the Galapagos Islands are used to reexamine quantitative analyses of species numbers and compositional similarities and it is shown that the number of botanical collecting trips is a better predictor of speciesNumbers than are area, elevation, or isolation. Expand
Origin of the New Hebridean avifauna
TLDR
The physical environment and avifauna of the New Hebrides in the Southwest Pacific are briefly described, and birds that colonize archipelagos 'upstream' towards the source of colonization often become restricted to small or remote islands, poor in species, thereby generating many of the supertramps of the Pacific.
