We investigate the effect of parasitoid phenology on host-parasitoid population cycles. Recent experimental research has shown that parasitized hosts can continue to interact with their unparasitized counterparts through competition. Parasitoid phenology, in particular the timing of emergence from the host, determines the duration of this competition. We construct a discrete-time host-parasitoi...

We describe and figure Moina hemanti sp. nov. from ephemeral pools on the campus of Pune University, India. Although the pools flood during the monsoon, the moinid only appears irregularly and for a short period of time. In morphology, it is extremely close to Moina dumonti from Mexico and Cuba. This geographic gap remains unexplained for the time being, although more similar cases among cladoc...
