Carbon dioxide emissions were measured on three di€erent days at di€erent soil temperature and the soil moisture conditions, and the soil properties were investigated at the same

There was a tendency for the mean serum progesterone concentra- tion in the early summer kidding group to be higher from 76 days (just prior to the natural breeding season)

As girth was not measured on all fish, drag was calculated using the average swimming speed found for each species on a subset of the fish (146 individual chinook salmon and

Ž Experiment 1. In each experiment the consumption of each food was measured over 7 days and the droppings around the bait boxes were counted to assess mouse activity. Food

Total weed biomass was measured at the first weeding, 3 months after planting (MAP), and total weed biomass and aboveground biomass, partitioning and nutrient accumulation of C.

Heat balance components for eight measurement periods (81 days) were used in the comparison. There was good agreement between model simulations and measurements. The average

The measurements showed that approximately 80% of the incoming net radiation was used as latent heat, reducing to a value between 71 and 76% in the summer months of 1995 and 1996

This transpiration model was validated against experimental data measured in a soil-less tomato crop cultivation in Avignon in summer conditions, when the greenhouse is open, and
