text: 'Net ecosystem production (NEP) is an important indicator of lake ecosystem
function and integrity. An earlier study, restricted to one geographical region,
indicated that oxygen saturation levels (DO%) might be used to predict daily NEP
in shallow lakes. To test the generality of the method, we used DO% data collected
in a standardised pan-European mesocosm experiment with contrasting trophic states
and water levels covering a large climate gradient (from Sweden to Turkey). We
corroborated these data with process-based DO simulations. The NEP ~ DO% relation
depended on factors influencing gas transfer: water depth and wind. The NEP ~ DO%
relation per volume became weaker with increasing depth (1–2 m) but was independent
of depth when area based. Simulations indicated that the marginalisation of the
depth was sensitive to wind conditions. Trophic status, temperature and light
showed no or only marginal (climate zone) effects (experimental data), while the
simulations indicated influence of those factors under particular wind–depth conditions.
We confirmed that when considering also wind and depth effects, midday DO% potentially
provides reliable estimates of daily NEP. Therefore, historical monitoring data
of DO% might be used to estimate NEP, and process-based oxygen models may be valuable
tool therein. We encourage further tests.'

text: Diet processing impacts on starch properties, such as the degree of starch
gelatinization. This affects digestibility, as shown in laboratory mice fed either
a pelleted or an extruded diet. In the present study, the morphology of starch
particles throughout the digestive tract of mice was visualized. Thirty-two female
C57BL/6J mice were used for a feeding trial. They were fed a commercial maintenance
diet for laboratory mice, which was available in pelleted and extruded form, for
seven weeks. The mice were sacrificed after the feeding period, and chyme samples
were collected from five sites (stomach, anterior and posterior small intestine,
caecum, colon). Samples of diets, chyme and faeces were analyzed via stereomicroscopy
(stained with Lugol’s iodine) and scanning electron microscopy (SEM). The starch
granules appeared more compact in the pelleted diet, showing first signs of degradation
only in the small intestine. The caecum content of both diets group was intensively
stained, particles as well as fluid phase, indicating that it contained mainly
starch. The SEM pictures of caecum content showed abundant bacteria near starch
particles. This suggests selective retention of prae-caecally undigested starch
in the murine caecum, likely the site of microbial fermentation.
