| Potassium permanganate incubation caused loss of reactivity with Congo red. |
| Starved border cells plated on to nutrient agar demonstrated no sign of contamination after 48 h incubation. |
| There is no support for the idea that female larks work harder during the chick rearing period compared with the incubation period. |
| Strict adherence to the specified time and temperature of incubations is essential for accurate results. |
| There was no measurable incorporation of C into sucrose, hexoses or the raffinose family of oligosaccharides at any stage of the incubations. |
| They show that Siberian permafrost carbon decomposes quickly when thawed, both in in-situ and laboratory incubations. |
