This review is the first assembling information on intersexuality in aquatic invertebrates, from
freshwater to estuarine and marine environments. Intersex is a condition whereby an …

I examine how the population biology of pelagic copepods depends on their mating biology
using field data and a simple demographic model. Among calanoid copepods, two distinct …

Post-embryonic development time, somatic growth, egg production rate, survival and sex
ratio for the marine calanoid copepod Pseudocalanus newmani from the Pacific coast off …

The important calanoid copepod species Calanus finmarchicus and C. helgolandicus have
distinct geographic ranges which are changing under the influence of climate change …

Female-biased adult sex ratios are common in copepod species, and have been observed
both in wild populations and in cultures. Biased sex ratios are most commonly explained by …

The effect of diatoms of the genus Cocconeis on the sex reversal of the shrimp Hippolyte
inermis Leach was examined in the laboratory. Randomised experiments were carried out to …

Abstract Effects of food availability and season on the free amino acid (FAA) and total protein
content of the copepod Calanus finmarchicus females were investigated in two mesocosm …

The effect of food concentration on the sex ratio in Calanus spp. has been investigated in
laboratory and mesocosm experiments. The results of the experiments are compared with …

Dating back to the early Cambrian period, crustaceans had ample time to undertake endless
experimentation with form and function. Today, no other group of plants or animals on the …

In environments with strong seasonality, many herbivorous zooplankton remain active only
during the productive season and undergo a period of inactivity and suppressed …
