Abstract 1. Termites (Isoptera) in tropical savannas are known as ecosystem engineers, affecting the spatial and temporal distribution of water, carbon, cations, and nutrients through their mound structures. Their mounds, however, also offer habitation to diverse taxa and feeding guilds of other invertebrates; a keystone role that has not been properly quantified. 

Termite cohabitation: the relative effect of biotic and abiotic factors on mound biodiversity

1. Termites are important ecosystem engineers that improve primary productivity in trees and animal diversity outside their mounds. However, their ecological relationship with the species nesting

Termite mounds house a diversity of taxa in oil palm plantations irrespective of understory management

We investigated the effects of oil palm understory vegetation management on termite mound activity and non‐termite inhabitants. We found a diversity of taxa, most of which were unaffected by

Would East African savanna rodents inhibit woody encroachment? Evidence from stable isotopes and microhistological analysis of feces

Grass was either coequal to browse (dicots) or dominated the plant portion of each species' diet, which was somewhat unexpected given rodents' hypothesized role in limiting Acacia recruitment.

The effect of elevation and time on mountain spider diversity: a view of two aspects in the Cederberg mountains of South Africa

Our aim is to test if long‐term patterns in α alpha and β beta diversity along an elevational transect on two aspects of a mountain are consistent through time using spiders as model organisms,

Spatial and temporal hotspots of termite-driven decomposition in the Serengeti.

This study suggests that intraspecific aspects of spatial heterogeneity and temporal variability deserve much greater consideration within the framework of ecosystem engineering.

Uncovering trophic positions and food resources of soil animals using bulk natural stable isotope composition

An overview of recent advances in uncovering the trophic structure of soil food webs using natural variations in stable isotope ratios is provided.

1. Termitophily in some rove beetles is commonly attributed to the striking termite worker resemblance that is provided by the beetles' hypertrophic (‘physogastric’) abdomen. However, a termite nest

Long‐term patterns of invertebrate abundance and relationships to environmental factors in arid Australia

The results show that invertebrates in arid ecosystems are influenced by a variety of abiotic factors, at multiple scales, and that responses to rainfall are not as strong or as predictable as those seen for other taxa.

Feeding habits and multifunctional classification of soil‐associated consumers from protists to vertebrates

A comprehensive review of the feeding habits of consumers in soil, including protists, micro-, meso- and macrofauna (invertebrates), and soil-associated vertebrates is provided, and an overarching classification across taxa focusing on key universal traits such as food resource preferences, body masses, microhabitat specialisation, protection and hunting mechanisms is compiled.

Stable isotope analysis of diet confirms niche separation of two sympatric species of Namib Desert lizard.

Stable isotope mixing models found that the two lizard species relied on a largely non-overlapping but seasonally variable array of arthropods and primarily acquired nutrients that originated from C4 /CAM plants.

Predation by invertebrates was observed on 11 species of termites, primarily Odontotermes latericius exposed while building their chimneys, and both soldiers and workers largely lack the behavioral repertoire to do so and defense is ineffective.

Future research directions need to include a greater concentration on the morphology of ant nests, more detailed assessment of the influence of ants and termites on soil structure and water infiltration, an increase in biopedological research in human-modified environments, a greater emphasis on termites and ants other than the most dominant or prominent species, and a focus on community as distinct from single-species effects.
