Modelling the evolution of holobionts: an incomplete review N. Z. J. Zool. (IF 1.3) Pub Date : 2023-09-06 Allen G. Rodrigo
ABSTRACT A holobiont is a biological individual that consists of a host and its associated microbiome. As a biological individual, a holobiont participates in the evolutionary process, although the dynamics of how it does so are non-trivial. In particular, the constituent members of the holobiont have their own fitnesses, and holobiont evolution has to be examined in the light of the complementary

Sequential analysis reveals use of mutual assessment in contests between wild New Zealand giraffe weevils N. Z. J. Zool. (IF 1.3) Pub Date : 2023-08-13 Rebecca J. LeGrice, Gregory I. Holwell, Christina J. Painting
ABSTRACT When resources such as mates or mating sites are limited, selection drives the evolution of complex and frequently violent fighting behaviour. Contest outcome is determined by an individual’s resource holding potential (RHP) in comparison to that of their opponent. During contests individuals may assess only their own RHP, or they may mutually assess both their own and their opponent’s RHP
