The forebrain and pituitary sites of synthesis of growth hormone secretagogue-receptor mRNA were identified in four adult lemurs (Microcebus murinus) by in situ hybridisation performed with a radiolabeled cRNA probe transcribed from human Growth Hormone Secretagogue-Receptor cDNA. The cRNA sense and antisense probes were hybridised to cryostat sections(More)
In mammals, a number of anatomical and functional changes occur in the circadian timing system with aging. In certain species, aging can be modified by various factors which induce a number of pathological changes. In a small primate, the gray mouse lemur (Microcebus murinus), long-term acceleration of seasonal rhythms by exposing the animals to a shortened(More)
The vomeronasal system (VNS) seems to be functional in some primates and involved in the detection of urinary signals. Anterograde tracing (WGA-HRP) and evoked metabolic activity (2-DG method) were used in order to clarify the conditions under which the VNS is activated in the prosimian mouse lemur. After WGA-HRP deposition at one of the oral entries of the(More)
In male lesser mouse lemurs, testicular size and plasma testosterone levels are controlled by photoperiodic variations but can be modified by urinary cues from conspecifics. To test whether urinary cues may have differential effects on testicular size and testosterone levels depending on the photoperiodic state of the receiver, isolated males were exposed(More)
Short-day-induced fattening was investigated in the small nocturnal primate Microcebus murinus. Animals were either transferred from long photoperiod (LP) to short photoperiod (SP) or maintained in LP and submitted to various treatments. Animals fed daily on 40 microg of melatonin (MEL) at two different times showed a significant increase in body mass(More)
Due to their differential reproductive investment, males and females often exhibit high differences in energy management. The main hypothesis tested in this study is that short photoperiod-induced fattening in the small primate Microcebus murinus is strongly affected by social cues. Short photoperiod-induced changes in body mass, lean mass and thyroid(More)
Wetland forests represent some of the most productive forest lands in the southeast. They are also an environ-mentallysensitive ecotype whii presents unique problems for forest operations. Sustaining active management in these areas will require systems which can operate on weak soil conditions without adversely affecting soil properties or stand(More)
