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
Would East African savanna rodents inhibit woody encroachment? Evidence from stable isotopes and microhistological analysis of feces
TLDR
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.
Spatial and temporal hotspots of termite-driven decomposition in the Serengeti.
TLDR
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
TLDR
An overview of recent advances in uncovering the trophic structure of soil food webs using natural variations in stable isotope ratios is provided.
Termitariophily: expanding the concept of termitophily in a physogastric rove beetle (Coleoptera: Staphylinidae)
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
TLDR
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.
Stable isotope analysis of diet confirms niche separation of two sympatric species of Namib Desert lizard.
TLDR
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.
Ecological and morphological response of rodents to environmental change over the late Quaternary
The rapid progression of modern climate change is already altering ecosystems worldwide. By employing the fossil record, we can investigate how animals responded to past climatic changes and
Trophic interactions in an ant nest microcosm: a combined experimental and stable isotope (δ13C/δ15N) approach
TLDR
This study provides unique insights into the complex interactions in a small symbiont microcosm system and suggests that the interactions between host and Symbiont might be mediated by other symbionts in the same community.
Soil CO2 Emissions Associated with Termitaria in Tropical Savanna: Evidence for Hot-Spot Compensation
Our understanding of carbon (C) dynamics within savannas is very limited, especially how source/sink dynamics are influenced by the resident biota. Previous measurements of epigeal termite mounds

Nitrogen and carbon isotope ratios in termites: an indicator of trophic habit along the gradient from wood‐feeding to soil‐feeding
1. Nitrogen and carbon stable‐isotope ratios (δ15N and δ13C) of body tissues, mound/nest materials and dietary substrates were determined in termite species with differing trophic habits, sampled
Invertebrate predation on termites of the African Savanna
TLDR
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.
Stable isotope analysis of termite food habits in East African grasslands
TLDR
Results are in agreement with the idea that organic carbon becomes enriched in 13C as it passes through a food chain.

Ants and Termites As Food
TLDR
This work has focused on the relationship between aardvarks and pangolins and ant- and termite-eaters in the context of general predator-prey relationships between mammals and ants and termites.

TLDR
It is concluded that using higher taxonomic units in soil food web analysis is problematic and in general not consistent with nature.

Abstract The δ 13 C values of the tissue carbon of 14 termite species showed clear differences, related to the ranges of their putative diets. Only small differences in tissue δ 13 C values were
Faunal Activities and Soil Processes: Adaptive Strategies That Determine Ecosystem Function
TLDR
This chapter illustrates the functional classification of soil organisms based on their adaptive strategies and suggests that the three systems defined, operate at nested scales of time and space and have decreasing overall effects on the determination of soil function in the order micro-foodwebs.

The role of termites and ants in soil modification - a review
TLDR
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.
