Neutral versus adaptive genetic variation in parasite resistance: importance of major histocompatibility complex supertypes in a free-ranging primate
Current discussions in evolutionary ecology and conservation genetics focus on the relative importance of using selective neutral markers or markers of coding genes to identify adaptive andExpand

Hibernation in the tropics: lessons from a primate
The Malagasy primate Cheirogaleus medius hibernates in tree holes for 7 months, although ambient temperatures during hibernation rise above 30°C in their natural environment. In a field study we showExpand

Extreme individual flexibility of heterothermy in free-ranging Malagasy mouse lemurs (Microcebus griseorufus)
Flexibility in physiological processes is essential to adequately respond to changes in environmental conditions. Madagascar is a particularly challenging environment because climatic conditions seemExpand

Physiology: Hibernation in a tropical primate
The Madagascan fat-tailed dwarf lemur, Cheirogaleus medius, hibernates in tree holes for seven months of the year, even though winter temperatures rise to over 30 °C. Here we show that this tropicalExpand

High rates of extra-pair young in the pair-living fat-tailed dwarf lemur, Cheirogaleus medius
Abstract Cheirogaleids are one of the most primitive extant primate taxa in the world. Their lifestyle and mating system, therefore, have been considered to be representative for social systems inExpand

Energetics of tropical hibernation
In this field study, the energetic properties of tropical hibernation were investigated by measuring oxygen consumption and body temperature of the Malagasy primate Cheirogaleus medius in theirExpand

Measuring body temperature in the field—evaluation of external vs. implanted transmitters in a small mammal
Measuring the body temperature of animals living under natural conditions has gained increasing interest. This study shows in the small lemur Cheirogaleus medius that for many questions externalExpand

Communally breeding bats use physiological and behavioural adjustments to optimise daily energy expenditure
Small endotherms must change roosting and thermoregulatory behaviour in response to changes in ambient conditions if they are to achieve positive energy balance. In social species, for example manyExpand

MHC-associated mating strategies and the importance of overall genetic diversity in an obligate pair-living primate
Mate choice is one of the most important evolutionary mechanisms. Females can improve their fitness by selectively mating with certain males. We studied possible genetic benefits in the obligateExpand

Flexible patterns in energy savings: heterothermy in primates
Heterothermy is an energy-saving strategy usually employed in response to environmental bottlenecks, which is common in almost all mammalian orders. Within the order primates, heterothermy has beenExpand
