The dominance-diversity relationship in ants
Plot showing the relationship between species richness and the abundance of dominant ants. The red line shows the decline in local species richness when invasive dominants are present, the orange line shows the pattern when only native dominants are present.

The dominance-diversity relationship in ants

A recent study by a team of international researchers, including former C·I·B post-doctoral associate, Tom Bishop, has shown that invasive dominant ant species have different effects on the diversity of the wider ant community than native dominant species.

Ant colour and body size respond strongly to the environment

A recent study by C·I·B post-doctoral fellow, Tom Bishop and colleagues has shown that the relative abundances of ants is strongly related to their thermoregulatory traits.

Food use of an invasive barnacle suggests potential for spread

The ability of an invasive barnacle to use available food resources shows likely spread along the South coast of South Africa. These findings come from work by Haley Pope (Former C·I·B student) and Tammy Robinson and Mhairi Alexander of the C·I·B.

Movement mysteries of largemouth bass

Largemouth bass (Micropterus salmoides) are a popular and valuable sport-fish for anglers. They were introduced into South Africa in 1928, and have since been widely distributed across southern Africa.
