The association between body mass, metabolic rates and survival of bank voles
2009
Summary 1Many studies have been performed in an attempt to explain physiological, ecological and evolutionary factors behind inter- and intraspecific variation in basal metabolic rate (BMR) and maximum aerobic metabolic rate (VO2max). However, very little is known about the association between the traits and fitness components in populations of free-living animals. 2We studied the association between body size and the metabolic rates of bank voles Myodes (= Clethrionomys) glareolus and their survival, measured by repeated trappings across 2 years in an isolated, island population. All measured traits (body mass, BM; head width, HW; VO2max and BMR) were significantly repeatable over short (m…
Spatial Distribution of Ethylene Production by Individual Needles Along a Shoot ofPinus sylvestrisL.: Relationship with Peroxidase Activity
1998
Spatial distribution of ethylene production by individual current year needles and the relationship with peroxidase activity was studied along a shoot of Scots pine (Pinus sylvestrisL.). Much variation in ethylene production between and within individual seedlings was found. There was a significant difference in mean intensity of ethylene production between orthostichies within individual seedlings. The capacity of individual needles to convert 1-aminocyclopropane-1-carboxylic acid (ACC) to ethylene did not correlate with the basal rate of ethylene production. Mean ethylene production intensity by orthostichies correlated positively with mean peroxidase activity. A positive correlation betw…
