On souligne le fait que la competition et la coevolution des especes en competition sont des faits reels et extremement importants au sein de certaines biocenoses (exemple d'Anolis), contrairement aux conclusions de certains auteurs 

Some differences between invasion-structured and coevolution-structured competitive communities: a preliminary theoretical analysis

TLDR
L'algorythme tenant compte du phenomene de coevolution peut expliquer le type de repartition des Anoles aux Petites Antilles and certains aspects du cycle taxonomique de Wilson.

Habitat disturbance modifies dominance, coexistence, and competitive interactions in tropical ant communities

TLDR
Interspecific competition is a major structuring principle in ecological communities and the outcome of competitive interactions is hard to predict, highly context‐dependent, and multiple factors can modulate such interactions.

Coevolution between interspecific plant competitors?

Asymmetrical competition between Neotropical dung beetles and its consequences for assemblage structure

Abstract.  1. This study combines the results of laboratory experiments using representative assemblage components and pitfall trapping over a large geographical area to examine the hypothesis that

Rainfall and Winter Sparrow Densities: A View from the Northern Great Basin

Des facteurs tels que la temperature et la couche de neige en hiver sont plus importants que les chutes de pluie en ce qui concerne l'abondance hivernale de Spizella passerina en Arizona

Competition and coexistence in an insular ant community, a manipulation experiment (Hymenoptera: Formicidae)

TLDR
The result of this ecological manipulation experiment shows that F. truncorum by weakening populations of Lasius niger may at the same time boost the nest numbers ofLasius jlavus and Leptothorax sp.

Is diet segregation between dabbling ducks due to food partitioning? A review of seasonal patterns in the Western Palearctic

Within the paradigm of resource-limited competition-structured communities, dabbling ducks (Anas spp.) have been used as a textbook example of how morphological differences, notably bill lamellar d

Long adult life, low reproduction and competition in two sub‐Antarctic carabid beetles

TLDR
Two opportunistic carnivores coexist in fellfield habitat above 120 m altitude, where they hunt prey in inter‐stone spaces in sub‐Antarctic Ile de la Possession and Iles Crozet.

Resource Partitioning and Interspecific Competition in Two Two-Species Insular Anolis Lizard Communities

TLDR
Population experiments with Anolis lizard species demonstrate a relation between the amount of between-species competition and the degree of interspecific resource partitioning (the more the partitioning the less the competition), which verifies, for these species, a central assumption of competition theory.

Diversity and the coevolution of competitors, or the ghost of competition past

TLDR
The notion of coevolutionary shaping of competitors' niches has little support at present, and theory and evidence suggest that it is probable only in low diversity communities.

TESTS OF COMMUNITY‐WIDE CHARACTER DISPLACEMENT AGAINST NULL HYPOTHESES

TLDR
Hespenheide has shown that arbitrary ratios among sympatric species are not good evidence for character displacement, because relationships between the size of trophic structure (or body size) and food size vary substantially within and among taxa.

Ecology and Evolution of Communities

TLDR
This chapter discusses the evolution of Species Abundance and Diversity in Communities Near Equilibrium and some Mechanisms Producing Structure in Natural Communities, as well as some mechanisms producing structure in natural communities.

The evolution of resource partitioning in a multidimensional resource space.

Heritability of external morphology in Darwin's finches

TLDR
It is shown here that several ecologically significant characters have high heritabilities in Darwin's medium ground finch (Geospiza fortis) and the role of intraspecific variation itself is the focus of attention.

Population experiments with the Anolis lizards of St. Maarten and St. Eustatius.

TLDR
Results support a central assumption of competition theory: the strength of inter specific competition increases as the amount of interspecific resource partitioning decreases.

TLDR
I have reconstructed data sets for some of the studies they described, following their criteria for island sympatry and hypothetical source fauna assembly, and used certain tests which are, on average, more powerful than the binomial test in rejecting the null hypothesis.
