Juvenile cannibalism may play an important role in population regulation of marine organisms with juvenile stages that aggregate in nursery habitats. I conducted a series of field and laboratory experiments to assess whether three potential density-depen- dent mechanisms could regulate local recruitment of juvenile shore crabs Carcinus maenas in Swedish nursery areas: (1) intracohort cannibalism, (2) juvenile cannibals' functional response to smaller conspecific prey densities, and (3) juvenile…

Cannibalism as a potential factor affecting recruitment of the invasive Asian shore crab Hemigrapsus sanguineus

Cannibalism of settling megalopae and newly settled juveniles by larger conspecifics could affect recruitment to benthic populations of this non-native crab species.

Effects of habitat complexity on cannibalism rates in European green crabs ( Carcinus maenas Linnaeus, 1758)

The idea that complex habitats have the potential to mediate predator–prey interactions, including adult–juvenile cannibalism in green crabs, is supported.

Interference competition for space in nursery habitats: density-dependent effects on growth and dispersal in juvenile shore crabs Carcinus maenas

The results suggest that interference competition for space and density-dependent emigration from refuge habitats, coupled with habitat-specific mortality, is an important regulating mechanism for juvenile shore crab populations, in particular for older juvenile cohorts that have escaped inter-cohort cannibalism through a size refuge.

Temporal variation in cannibalistic infanticide by the shore crab hemigrapsus oregonensis: Implications for reproductive success

This is the first time crabs have been shown to suppress feeding to reduce cannibalism of larvae, and this behavior could affect reproductive success and population dynamics.

Trophic Ecology of Juvenile Southern King Crab Associated with Kelp Forest: Evidence of Cannibalism

The southern king crab, Lithodes santolla, is a well-known predator/scavenger species during its adult phase but its feeding strategy in early stages is less studied. This information is important to



Predation on postlarvae and juveniles of the shore crab Carcinus maenas: importance of shelter, size and cannibalism

The results indicate that predation is an important process that can create a bottleneck for juvenile shore crab populations during settlement and early juvenile stages, mediated by the availability of nursery habitats and proposes that habitat- and size-specific predation by small epibenthic predators are an important selective force in habitat selection by postlarvae and ontogenetic shifts in habitat use by juveniles.

Density-dependent cannibalism in larval dragonflies

It is demonstrated that cannibalism was strongly density dependent and may contribute to population regulation of dragonflies in temporary ponds and contribute to emergence synchrony.


The results from this study demonstrate that substrate selection can affect distribution of juvenile crab, and that predation is a key factor regulating local population size of early juvenile crabs in intertidal habitats where postlarval supply is relatively high.

Settlement behavior in shore crabs Carcinus maenas: why do postlarvae emigrate from nursery habitats?

A conceptual model of settlement in the shore crab is proposed where the dynamic behavior of the postlarvae is an adaptation to diel differences in predation risk between the settlement habitat and the plankton.

Consequences of cannibalism and competition for food in a smallmouth bass population: An individual-based modeling study

It is found that competition and cannibalism produced intraclass and interclass density dependence in the age-0 fish during the growth season and overcompensation occurs.

Variable Functional Responses of a Marine Predator in Dissimilar Homogeneous Microhabitats

It is suggested that variable blue crab functional responses result in microhabitat-specific mortality rates of benthic prey, and indicated that functional responses can differ significantly according to the physical properties of topographically simple habitats.

Wandering behaviour of the mud-crab Helice tridens related to evasion of cannibalism

Results suggest that burrows provide protection from predation and Habitat segregation due to migration of large individuals to the lagoon and dispersion of small ones in the reed marsh may lessen the chance of cannibalism.


Overconvergence resulted from the insensitivity of the survivorship of the original adults of the Notonecta hoflmanni to differences in food supply between treatments, allowing them to continue to affect the eventual density of the new overwintering popu- lation.
