| Peak and relative density counts were combined to arrive at density estimates for each species in each year at each blind. |
| In order to estimate the population density we divide the estimated abundance by the effective sample area. |
| The idea of lush fertility is further emphasized by the density of the well-watered clover crop that fully occupies a quarter of the foreground. |
| Bone mineral density of the lumbar spine and proximal femur were measured with dual energy x ray absorptiometry. |
| For this reason, separate mechanisms of acclimation for regulation of stomatal density on adaxial and abaxial surfaces have been proposed. |
| It is the secret, the mystery of quicksilver, that a metal of such enormous density can yet remain liquid. |
