U–Pb ages were determined by split-stream LA-SF/MC-ICPMS in garnets from UHT granulite xenoliths (Star mine, South Africa; 124 Ma). They give a considerable age range of 400 million years with well-defined maximas at 3.09, 3.01 and 2.75 Ga. The oldest peak overlaps with the changeover from tonalites to K-granites at 3.14–3.04 Ga and with zircon ages of the mid-crustal granulites of the Vredefort dome (3.1 Ga) in the wake of th...

Reference ranges provide a powerful tool for diagnostic decision-making in clinical medicine and are enormously valuable for understanding normality in pre-clinical scientific research that uses in vivo models. As yet, there are no published reference ranges for electrocardiography (ECG) in the laboratory mouse. The first mouse-specific reference ranges for the assessment of electrical conduction are reported herein generated...

Timing of reproduction is an important life‐history trait that varies among species as a function of energy allocation strategy, particularly as individuals are influenced by seasonal variations prior to and during the reproductive season. This study investigated size‐ and sex‐based seasonal patterns of energy allocation in bluegill, L epomis macrochirus (Rafinesque) , a species that spawns repeatedly throughout the summer, by...
