Extraordinary lifespans in ants: a test of evolutionary theories of ageing
TLDR
It is shown that the evolution of eusociality is associated with a 100-fold increase in insect lifespan, predicted by evolutionary theories because termite, bee and ant queens live in colonies that are sheltered and heavily defended against predators.
Problems of allometric scaling analysis: examples from mammalian reproductive biology
TLDR
A new non-parametric line-fitting technique has been developed that eliminates requirements for normality of distribution, greatly reduces the influence of outliers and permits objective recognition of grade shifts in substantial datasets, applied in scaling analyses of mammalian gestation periods and of neonatal body mass in primates.
PHYSIOLOGICAL TRAITS AFFECTING THE DISTRIBUTION AND WINTERING STRATEGY OF THE BAT TADARIDA TENIOTIS
TLDR
The hypothesis that Tadarida teniotis, the molossid species reaching the highest latitude worldwide (46° N), lacks the extreme physiological adaptations to cold that enable other sympatric bats to enter further into the temperate zone is tested.

TLDR
The metabolic and thermoregulatory traits studied in tree bats are generally similar to those of non-tropical bats roosting in caves and buildings.
Energetic strategies of shrews: ecological constraints and evolutionary implications
TLDR
It is speculated that climate and resource availability impose narrow limits on the evolution of these energetic strategies, mainly because of the small thermal inertia and reduced energetic autonomy of shrews.
Rate of metabolism and temperature regulation in two small tropical insectivorous bats (peropteryx macrotis and natalus tumidirostris)
TLDR
These bats have different basal rates of metabolism, thermal conductances, and body temperatures during nonnothermic rest, and thermal conditions at the roost and the availability of food and water may explain the observed BMR differences.
BASAL RATES OF METABOLISM OF NECTARIVOROUS BATS (PHYLLOSTOMIDAE) FROM A SEMIARID THORN FOREST IN VENEZUELA
TLDR
The hypothesis that ecological factors, such as roost microclimate and diet, influence rates of metabolism in phyllostomid bats is supported, as well as the hypothesis that metabolic heat production within a colony elevates air temperatures within caves to 33-340C.
Thermal Ecology of Moustached and Ghost-Faced Bats (Mormoopidae) in Venezuela
TLDR
It is hypothesized that roost temperature is an important selective force in the evolution of thermoregulatory patterns and basal rate of metabolism in bats and that adult females have lower basal rates of metabolism than conspecific males.
Energy requirements during reproduction and reproductive effort in shrews (Soricidae)
TLDR
The hypothesis that a higher basal rate of metabolism is associated with a higher reproductive effort in shrews is supported and leads to an earlier increase in the energy requirements and thus is an energetically more expensive reproductive mode.
