Laura Escobar-Pérez,Rosa Vargas-Poussou method used gut analysis to estimate the selectivities of daphnids feeding in a broad size range of a single particle type, including polystyrene beads (4–60 .m diameter) in the laboratory and . colonies (10–90 .m) in the field. In the second method, . of different sizes fed in a mixture of 6.5 .m

Distal Renal Tubular Acidosis (Type I DRTA),were either kept at constant high or low food levels or subjected to alternating periods of high food and starvation. Some animals were starved continuously after they had deposited their first clutch of eggs. Eggs were measured and weighed and their density (dry mass per volume) was determined. The

Especially, P-limited cells passed through the gut mostly intact, while N-limited cells were partly assimilated. Also, algae exposed to moderate doses o

At the lowest latitudes, some species are found only at high altitudes, but occur at progressively lower altitudes with increasing latitude: . and . are good examples. A study in South America, with a smaller database, gives similar results.
