“…Larval crowding has been found to play a role in modifying many vital functions in several experimental organisms: in particular it consistently depresses the number of offspring per female (Frank et al, 1957;Barker & Podger, 1970). A similar result was found by Hoppenheit (1976) in populations of Tisbe holothuriae.…”

Tisbe clodiensis and T. holothuriae females and males were maintained at different densities, from sexual maturity to the extrusion of the first egg sac, in order to study the effect of crowding on the number of nauplii produced by the first egg sac. They were tested in pure cultures at densities of 1, 2, 4, 6 and 8 couples per 20 ml of sea water, and in mixed cultures (half of the individuals belonging to each of the two species) with 2, 4, 6 and 8 couples per 20 ml, without food limitation. At the highest crowding level, and for T. holothuriae only, the effect of daily renewal of the culture water was examined. The mean number of nauplii per female decreases with increased density. A significant linear regression of number of nauplii on number of couples was found. The regression slopes appear to be the same for both species, regardless of whether they are cultured singly or together. The daily renewal of water diminishes the effect of crowding. The possibility that a complex chemical compound, produced by the animals, which enables the latter to perceive and to react to crowding, is discussed.

“…Such effects are well documented in plants (e.g., Solbrig et al 1988, Gillman et al 1993, Silva Matos et al 1999) and animals (e.g., Pennycuick 1969, Longstaff 1977, Clutton-Brock et al 1997, Tanner 1999, Cushing et al 2003. Density-dependence has been intensively studied in the laboratory (e.g., Pearl et al 1927, Frank et al 1957, Costantino and Desharnais 1991, Carey et al 1995, Mueller and Joshi 2000, Cushing et al 2003. It can arise from competition for food, space, or other resources, or from interactions (e.g., cannibalism) among individuals.…”
