MANY animals restrict their foraging activities to certain times of the day or night, but the Saharan silver ant Cataglyphis bombycina is exceptional in that all foragers leave their underground nest in an explosive outburst confined to a few minutes per day during the hottest midday period. The foraging activity of this 'thermophilic' ant is compressed into a small thermal window by predatory pressure on the one hand and heat stress on the other. 
Foraging patterns and strategies in an Australian desert ant
TLDR
This species daily activity schedule and diet composition is investigated, and foraging behaviour is examined; Melophorus bagoti foragers have the ability to recruit nestmates to profitable food sources, but the exact mechanism requires further investigation.
The ontogeny of foragwehaviour in desert ants, Cataglyphis bicolor
Abstract. 1. Individually foraging desert ants, Cataglyphis bicolor, exhibit short foraging lives (half lifetime, i.e. half‐time of the exponential decay function: 4.5 days), in which they perform
Social Life in Arid Environments: The Case Study of Cataglyphis Ants.
TLDR
Recent advances regarding the physiological, behavioral, life-history, colony, and ecological characteristics of Cataglyphis are reviewed and perspectives on future research that will build the understanding of organic adaptive responses to desertification are considered.
Traveling in clutter: Navigation in the Central Australian desert ant Melophorus bagoti
TLDR
Recent studies on this species concerning its use of habitual routes, distant landmarks, landmarks around the nest, and path integration, which is keeping track of the distance and direction traveled from one's starting point are reviewed.
Foraging ecology of the thermophilic Australian desert ant, Melophorus bagoti
The paper describes the foraging ecology of the Australian desert ant, Melophorus bagoti, a thermophilic, diurnal scavenger with ground-nesting colonies. Overlapping foraging ranges, low foraging
eview raveling in clutter : Navigation in the Central Australian desert
The Central Australian desert ant Melophorus bagoti is the most thermophilic ant on the continent. It comes out to forage during the hottest part of the day in the summer months. The ant shares a
Different effects of temperature on foraging activity schedules in sympatric Myrmecia ants
TLDR
It is concluded that temperature determines the timing of foraging as well as the daily and seasonal foraging activity in M. croslandi, but has less obvious effects on M. pyriformis.

Coexisting in harsh environments: temperature-based foraging patterns of two desert leafcutter ants (Hymenoptera: Formicidae: Attini)
TLDR
The results suggest that these two species have different thermal tolerance ranges that result in temporally separated foraging activities, and suggest that interference competition may have driven this temperature and temporal specialization in these two sympatric species.
Temperature and water relations in desert bees
TLDR
Endothermy in bees may have evolved primarily in arid zones, and served as a pre-adaptation for subsequent invasion of cool temperate biomes.

Foraging Activity of the Western Harvester Ant in the Shortgrass Plains Ecosystem
TLDR
Activity times of Pogonomyrmex occidentalis (Cresson) were found to vary with soil surface temperatures, and studies conducted on populations in lightly- and heavily-grazed pastures showed no significant differences in the rate of foraging extraction, foraging distance, time per foraging trip, or availability of forage (seeds).

TLDR
It is indicated that ants could tolerate temperatures >CTM for short periods and that short but frequent thermal respites facilitated ant survival at temperatures = CTM.
Temperature tolerances in the Namib Desert dune ant, Camponotus detritus
TLDR
The mean preferred temperature of workers and brood of Camponotus detritus was 35°C at 100% r.h. and the critical maximal temperature was 53°C while the critical minimal temperature was 4.57°C on average for 24 h.
Mandibular Gland Secretions as Alarm Pheromones in Two Species of the Desert Ant Cataglyphis
TLDR
Mandibular gland secretion of two Cataglyphis species were chemically analyzed by combined gas chromatography mass spectrometry and found that C. bombycina consisted of citronellol and geraniol while that of C. nigra contained only Geraniol.
Activity patterns of some Namib Desert ants
TLDR
The activity patterns of eight epigaeic ant species from the Namib Desert were studied in summer and winter, and before and after a rainfall event, finding that interspecific differences in activity pattern were greater in summer than winter.

This work discusses the maintenance of Physiological Homeostasis in the Desert Environment, growth and Population Dynamics of Desert Reptiles, and Causes and Incidence of Mortality in Desert Lizards.
Metabolism and activity of the spanish fringe-toed lizard (Lacertidae: acanthodactylus erythrurus)
TLDR
Because these lizards initiate activity at black body temperatures of 13°C in their natural habitat, the ability to sustain high rates of aerobic metabolism at low temperatures is probably valuable.

TLDR
A heat transfer analysis of animals is presented which lies between detailed thermal energy budget analysis and the simplified “Newton's Law of cooling” approach, and it is possible to make direct measurements of Te, K0, Tes, and M∗ with taxidermic models of the animal.
