It is found that many arboreal ant species obtain little N through predation and scavenging, and microsymbionts of ants and their hemipteran trophobionts might play key roles in the nutrition of taxa specializing on N-poor exudates.
The role of resource imbalances in the evolutionary ecology of tropical arboreal ants

Dietary ratios of CHO:protein play an important and previously unrecognized role in the ecology and evolution of ants generally and modifications of worker digestive systems in certain ant sub-families and genera represent key innovations for handling and processing large volumes of liquid food.
Dielectric Relaxation in Glycerol, Propylene Glycol, and n‐Propanol
- D. Davidson, R. Cole
- Chemistry
- 1 December 1951
Complex dielectric constants have been measured at frequencies from below 20 c/s to 5 mc/s over the temperature range −40° to −75°C in glycerol, −45° to −90° in propylene glycol, and −80° to −140° in…

New Perspectivesis intended to allow the communication of comments, viewpoints and speculative interpretation of issues in ecology pertinent to entomology, and to fuel discussion and debate.
Ecological Studies of Neotropical Ant Gardens

In a census taken in Peru's Manu National Park, 10 epiphytic angiosperms from seven plant families established principally on arboreal carton-ant nests, finding that preadaptations of plants and ants appear to have been very important to the origin of AGs.

Some of the most challenging questions of contemporary biology concern the diversity and stability of ecological communities. In most natural habi tats many coexisting species of plants, animals,…

Parallels between these two groups suggest that limits to specialization and overlap may be specified by parameters such as resource abundance and predictability that affect unrelated taxa similarly.
Granivory and competition as determinants of annual plant diversity in the Chihuahuan desert

- Environmental Science
- 1 October 1992
Results here contrast with earlier experiments in the Sonoran Desert, where ants and rodents interacted principally through populations of winter annuals, and increasing dominance of large-seeded annuals on rodent-removal plots eventually led ant populations to decline.
FORAGING ECOLOGY AND COMMUNITY ORGANIZATION IN DESERT SEED-EATING ANTS'

- 1 July 1977
Colonies of Pogonomyrmex rugosus exhibited a mixed foraging strategy, with the most distinct feeding columns occurring during a period of peak seed abundance.
