Partitioning of Time as an Ecological Resource
TLDR
The decade-long study of spiny mice of rocky deserts demonstrates that, while different factors select for activity patterns, endogenous rhythmicity may be an evolutionary constraint. Expand
SIRT6 protects against pathological damage caused by diet‐induced obesity
TLDR
Gene expression analysis of adipose tissue revealed that the positive effect of SIRT6 overexpression is associated with down regulation of a selective set of peroxisome proliferator‐activated receptor‐responsive genes, and genes associated with lipid storage, which were suggested as potential targets for drugs to control metabolic syndrome. Expand
Monitoring of natural and synthetic hormones in a polluted river.
TLDR
The data suggest that hormones in readily measured quantities can be transported considerable distances from the source of pollution. Expand
Dissociation of leptin secretion and adiposity during prehibernatory fattening in little brown bats.
TLDR
It is concluded that in the early prehibernatory phase, BMR decreases despite increasing plasma leptin levels, suggesting a state of relative leptin resistance at that time, and at later stages, adiposity increases as BMR continues to decrease, and plasma leptin becomes dissociated from adiposity.

Chronobiology by moonlight
TLDR
The ecological and behavioural evidence showing the effect of moonlight on activity is reviewed, the adaptive value of these changes are discussed, and possible mechanisms underlying this effect are described. Expand
POPULATION BIOLOGY AND SPATIAL RELATIONSHIPS OF COEXISTING SPINY MICE (ACOMYS) IN ISRAEL
TLDR
Acomys russatus showed a significant preference for boulder habitat versus open habitat at all seasons, whereas A. cahirinus showed a preference for bouldering habitat only half of the time, and sexes of both species overlapped in home range. Expand
In search of a temporal niche: environmental factors.
TLDR
This work underscores the importance of the 24-h time axis as critical variable in the ecological niche, and describes a new hypothesis of circadian thermoenergetics which may explain several cases of temporal niche switching in mammals. Expand
On the role of phylogeny in determining activity patterns of rodents
TLDR
It is clear that phylogeny constrains the evolution of activity patterns in rodents, and may limit their ability to use the time niche axis for ecological separation. Expand
Circadian rhythms and depression: Human psychopathology and animal models
TLDR
It is suggested that an important factor hindering research into the underlying mechanisms is the lack of good animal models and it is proposed that additional efforts in that area should be made. Expand
Two sides of a coin: ecological and chronobiological perspectives of timing in the wild

  • 19 November 2017
TLDR
It is argued that ecological and chronobiological perspectives are complementary, and that studies at the intersection will enable both fields to jointly overcome obstacles that currently hinder progress, and to achieve this integration, some conceptual barriers have to be crossed. Expand
