Ant Biodiversity and Community Ecology

Ants (Formicidae) represent one of the most speciose and ecologically significant insect families, occupying a broad range of terrestrial habitats worldwide. They contribute to soil turnover, nutrient cycling, seed dispersal and predation, and their eusocial organisation underpins complex colony life-cycles and division of labour. The diversity of ant communities is shaped by gradients of climate, elevation, habitat structure and disturbance, with species richness and composition responding to niche filtering, competition and habitat heterogeneity. Functional traits such as body size, leg length and mandible shape determine foraging strategies and ecological roles, giving rise to patterns of functional diversity and redundancy that influence ecosystem resilience. Landscape alteration—from deforestation and agriculture to plantation forestry—alters taxonomic and functional composition, often leading to homogenisation and loss of rare or specialised species. Concurrently, global change drivers such as rising temperatures and altered precipitation regimes impose new selective pressures on thermal tolerance, nesting behaviour and community assembly. Investigations at local to global scales integrate trait-based, phylogenetic and spatial modelling approaches to elucidate the processes maintaining ant biodiversity and predict responses to environmental change, informing conservation planning and restoration practices across tropical and temperate regions.

Recent studies have revealed that long-term forestry practices such as Eucalyptus plantations reduce both taxonomic and functional diversity of ant communities, driving functional homogenisation even after decades of natural regeneration. Managed plantations support only a subset of generalist species, while abandoned sites recover some local richness but fail to restore historic trait distributions. The persistence of similar community composition across plantation landscapes underscores the lasting impacts of monoculture forestry on ecosystem processes and highlights the need for restoration strategies that address both species identity and functional trait diversity.

Ant Biodiversity and Community Ecology publication trend

The graph below shows the total number of articles in ant biodiversity and community ecology across all publications each year (not limited to Nature Index journals).

Technical terms

Biodiversity: The variety and variability of living organisms, encompassing species richness, evenness and genetic variation.

Community ecology: The study of interactions between species within ecological communities and the processes that structure them.

Functional diversity: The range of ecological functions performed by species in a community, often characterised by variation in morphological or physiological traits.

Morphospace: A multidimensional representation of morphological trait variation among species.

Functional redundancy: The extent to which multiple species perform similar ecological roles, providing resilience against species loss.

Endemism: The ecological state of being unique to a defined geographic location, such as an island, region or habitat.
