Among nine species of a tropical community ecomorphological correlates were sought throughout ontogeny. Ontogenetic changes were distinguished by establishing six pre-defined size-classes. Morphometric data associated with feeding were compared by canonical correspondence analysis to dietary data. This analysis revealed seven significant relationships, showing 71% of the morphological variance explained 77% of the variance in diet. Based on funtional ecomorphological relationships established…

TLDR
The tests revealed weak correlations indicating that in addition to morphology, other factors like behavioural, physiological and evolutionary constraints together are likely to play an important role in ecosystem structuring of these complex tropical assemblages.
Ecomorphological patterns of the fish assemblage in a tropical floodplain: effects of trophic, spatial and phylogenetic structures
TLDR
Data indicate that the fish assemblage of the upper Parana River floodplain is structured ecomorphologically mainly according to trophic structure rather than habitat.
Dietary-morphological relationships in fish assemblages of small forested streams in the Bolivian Amazon
TLDR
Results show that even if morphology may set limits to patterns of resource use, these limits are broad enough to allow fishes changing their choice of prey resources to respond to local biotic and/or abiotic conditions.
Diet-morphology relationship in a fish assemblage from a medium-sized river of French Guiana: the effect of species taxonomic proximity
TLDR
It is concluded that controlling for phylogeny is essential to the detection of relationships between diet and morphology, and that, despite the robustness of some relationships between morphology and diet, many diets cannot be inferred by a ecomorphological approach.
Dietary–morphological relationships in a fish assemblage of the Bolivian Amazonian floodplain
TLDR
Morphological correlates of diet were examined in 48 species of freshwater fishes from floodplain lakes in the central part of the Mamore River to support both the hypotheses that species morphology influences the diet and that morphological similarity is conserved even in comparison with taxonomically unrelated species.
Ecomorphology and resource use by dominant species of tropical estuarine juvenile fishes
TLDR
Data indicate that similarity of ecomorphological forms, which minimize the influence of environment and partitioning of food, would help facilitate the co-existence of these fish when they are abundant in this tropical estuary.
Trophic ecology of terapontid fishes (Pisces: Terapontidae): The role of morphology and ontogeny
TLDR
Examination of the morphological correlates of the diet of 21 species of northern Australia’s terapontids and their constituent ontogenetic trophic units demonstrates that selective pressures have driven morphology in terAPontids to converge morphologically with other ecologically comparable fishes across the globe.
Patterns of morphological traits shaping the feeding guilds in the intertidal mudflat fishes of Indian Sundarbans.
TLDR
This study maintains the assumption that broad morphological differentiation acts as one of the underlying processes resulting in dietary variations that results in the varying modes of resource utilization by the coexisting species thereby determining the structure of a trophic guild.

Seasonal changes in morphological structuring in a guild of benthic stream fishes
TLDR
It is concluded that ecomorphological models may be properly applied to community subsets, but the interpretation of the model must consider the nature of the data set with respect of seasonality.
Morphological and Dietary Structuring of a Zambian Insectivorous Bat Community
TLDR
A model of community organization for closely related species in which a relatively large number of specialists with invariant attributes are clustered near the community centroid and a smaller number of distinctive, variable species occupy niches more distant from the centroid is led.
A functional approach to ecomorphological patterns of feeding in cottid fishes
TLDR
To examine ecomorphological relationships in the diets of cottid fishes from the northeastern Pacific by using functional classifications of predators and of prey, performance tests indicated that larger-mouthed cottids had significantly higher capture success on Heptacarpus shrimp than did smaller- mouthed species.
The Correlation Between Ecology and Morphology in Deciduous Forest Passerine Birds
TLDR
Although morphology predicts foraging behavior in this data set, considerable morphological variation is not related to the foraging variables that characterize the species' ecological relationships.
A Morphological Analysis of the Structure of Communities of Lizards in Desert Habitats
TLDR
The present analysis provides little indication of interaction between species according to morphological attributes, and some patterns revealed by studies of ecological relationships in the same localities are confirmed.
Ecomorphological analysis of fish taxocenes in rainforest streams of northern Borneo
TLDR
Attribute comparisons among the river systems revealed a progression towards more sedentary benthic morphologies with increasing average species richness and niche compression as a consequence of increasingAverage species richness was indicated by a reduction in length of life and average size, and was associated with development of complex life-history and reproductive styles.
Ecomorphology as a tool in fisheries: identification and ecotyping of Lake Tana barbs (Barbus intermedius complex), Ethiopia
TLDR
From knowledge of available food organisms and the trophic segregation thus found among barbs and sympatric species, a preliminary food web has been constructed and provides a biological framework for rational fisheries management aiming at sustainable production and protection of biodiversity.
ECOMORPHOLOGY AND BIOGEOGRAPHY OF A TROPICAL STREAM FISH ASSEMBLAGE: EVOLUTION OF ASSEMBLAGE STRUCTURE'
TLDR
The data favor the hypothesis that the ecomorphological relationships exhibited by these fishes may be the results of evolutionary adjustments to facilitate resource partitioning, thereby reducing interspecific competition.
Morphological Divergence During Growth in the Large Barbs (Barbus Spp.) of Lake Tana, Ethiopia
TLDR
The distinction of the morphotypes in small specimens supports the hypothesis that several distinct Barbus species exist in Lake Tana, and demonstrates that 11 of the 14 morphotypes can already be distinguished by their general external features at fork lengths of less than 12 cm.
Community Organization in Fishes as Indicated by Morphological Features
TLDR
Results indicate that consistent patterns do exist in the organization of these stream communities, and that the species currently living together are not a random assortment of species and do not randomly divide their resources.
