Alder-Frankia interaction and alder-poplar association for biomass production

Alders have an important role to play in biomass producing stands because of their N₂-fixing ability and their capacity to withstand soils having an excess of moisture. The objectives of preliminary trials were (...

Nutrition and burrowing energetics of the Cape mole-rat Georychus capensis

At 22°C the resting oxygen consumption of G. capensis is 1.13±0.05 cm³O₂·g^-1·h^-1 (mean± S.E.). In loose sandy soil the burrowing metabolic rate was approximately three times that of resting (3.41±0.19 cm³O₂·g^-1· ...

Actinorhizal host-specificity of Chinese Frankia strains

Cross-inoculation studies of numerous Frankia strains of Asian origin, primarily Chinese, were undertaken to determine whether previously described host specificity groups (HSG) were valid. Each strain was inocul...

S-locus products in Nicotiana alata pistils are subject to organ-specific post-transcriptional processing but not post-translational processing

The expression of genes encoding self-incompatibility ribonucleases (S-RNases) in Nicotiana alata were examined at both protein and RNA level for organ specificity. S-RNases recovered from stigmas and styles were...

Ecological and life-history correlates of cooperative breeding in South African birds

Our analyses of the incidence of cooperative breeding among South African birds differ from previous studies performed elsewhere in two respects. First, we distinguish between “obligate” (i.e. regular) and “fa...
