Games among cannibals: competition to cannibalize and parent‐offspring conflict lead to increased sibling cannibalism [PDF]
AbstractSibling cannibalism occurs in many species, yet understanding of sibling cannibalism as an adaptation currently lags behind understanding of other antagonistic interactions among siblings. Observed sibling cannibalism phenotypes likely reflect the interaction between competitive games among siblings and parent‐offspring conflict.

Sibling cannibalism in dorada under experimental conditions. I. Ontogeny, dynamics, bioenergetics of cannibalism and prey size selectivity [PDF]
Cannibalism among embryos and larvae of Brycon moorei (Characidae) occurs during daytime and night‐time, and persists under permanent darkness. Embryos and larvae of dorada provisioned with formulated feed over the first week of exogenous feeding did not survive, except for those exerting cannibalism.

The influence of female oviposition strategy on sibling cannibalism in the ladybird beetle Harmonia axyridis (Coleoptera: Coccinellidae) [PDF]
I hypothesized that sibling cannibalism is one of maternal investment in that a female controls sibling cannibalism. To test the hypothesis, I conducted a laboratory experiment and field observations to investigate sibling cannibalism in relation to ...

Sibling cannibalism in juvenile barramundi, Lates calcarifer (Actinopterygii: Perciformes: Centropomidae), reared under different light conditions [PDF]
Background. Cannibalism occurs at various ages or sizes depending on fish species and the respective environments. Barramundi, Lates calcarifer(Bloch, 1790),is a popular and valuable species in aquaculture on the Asian and Australian continents.

Effect of stocking density on the dynamics of cannibalism in sibling larvae of Perca fluviatilis under controlled conditions [PDF]
The effect of stocking density (10, 31.6 and 100 larvae 1; three replicates per treatment) on the day-by-day dynamics of survival, growth and cannibalism was examined in sibling perch larvae reared from eyed-egg stage in 100-1 cages (16L:8D, 20.0 ± 0.5°C, O ≥ 6.0 mg 1; feeding in excess with live Artemia nauplii during the photophase) during the first ...

Sibling Rivalry: Estimating Cannibalization Rates for Innovations [PDF]
Abstract To evaluate the success of a new product, managers need to determine how much of its new demand is due to cannibalizing the company’s other products, rather than drawing from competition or generating primary demand. A new model allows managers to estimate cannibalization effects and to calculate the new product’s net demand, which may be

Cannibalism in cultured Eurasian perch, Perca fluviatilis (Actinopterygii: Perciformes: Percidae)—Implication of maternal influence, kinship, and sex ratio of progenies [PDF]
Background. Intra cohort cannibalism is one of the main factors that affects the growth and survival of cultured fishes, especially in the larval and juvenile stages.

Many aphidophagous ladybird beetles lay clusters of eggs and sibling cannibalism occurs at hatching. Larvae that hatch early tend to cannibalize undeveloped eggs and those that hatch late.

Natural enemy defense, provisioning and oviposition site selection as maternal strategies to enhance offspring survival in a sub-social bug. [PDF]
The influence of maternal defense against natural enemies, maternal provisioning and oviposition site selection on offspring survival before and after hatching were examined in a semelparous pentatomid bug, Ramosiana insignis.

Synchronized hatching as a possible strategy to avoid sibling cannibalism in stink bugs [PDF]
In some animals, timing of egg hatching is adjusted in response to cues from clutch mates to synchronize hatching within a clutch and this typically facilitates mass migration of hatchlings from their natal clutch. A recent study in eight species of Pentatomidae revealed that four species show synchronized hatching due to responses to earlier-hatched ...
