Sibling cannibalism occurs across diverse taxa and can affect population size and structure, as well as the fitness of parents and the cannibal, via density effects and variation in individual propensity to cannibalize. We examined these effects on sibling cannibalism in juveniles of a web-building spider (Latrodectus hasselti, Australian redbacks). Adult redbacks are solitary, but juveniles live in clusters of variable density for a week after hatching. We confined newly hatched siblings from… Expand
Extreme developmental synchrony reduces sibling cannibalism in the black widow spider, Latrodectus hesperus
The more novel hypothesis that siblicide then may be reduced to the extent that maternal investment yields developmental synchrony and size-matched siblings is tested, paying particular attention to their relevance to the black widow's emerging role as an urban pest. Expand
Chemical signals might mediate interactions between females and juveniles of Latrodectus geometricus (Araneae: Theridiidae)
Behavior and cuticular chemical profiles analysis of females and juveniles of different ages show that females, regardless of their reproductive state, tolerate juveniles of other females with up to 40 days post-emergence and attack juveniles of 80 days after the emergence of juveniles in Latrodectus geometricus.

Diet composition and social environment determine food consumption, phenotype and fecundity in an omnivorous insect
The results highlight that insects may acquire and invest resources in a different manner when subjected to an intense interaction with conspecifics or when isolated, and while only diet composition affected individual reproductive output, the social environment would determine the number of reproductive females, thus indirectly influencing population performance.

Silkomics: Insight into the Silk Spinning Process of Spiders.
A general mechanism of action for the identified proteins in the silk-producing glands from the Nephila clavipes spider was proposed; the current results indicate that the webs play an active role in prey capture. Expand
Black Widow Optimization Algorithm: A novel meta-heuristic approach for solving engineering optimization problems
The results indicate that the proposed BWO algorithm has numerous advantages in different aspects such as early convergence and achieving optimized fitness value compared to other algorithms, and has the capability of providing competitive and promising results. Expand
Silk‐Based Fine Dust Filters for Air Filtration
State-of-the-art air filter devices have been well-characterized and optimized for particle deposition of a huge range of particle sizes. However, sustainability of the employed filter materials isExpand


Family Affects Sibling Cannibalism in the Black Widow Spider, Latrodectus hesperus
Novel data is presented suggesting family effects seem to be responsible for cannibalism in L. hesperus spiderlings, and several mechanisms that could explain the persistence of family-level variation in cannibalism, a trait that seems likely to be subject to strong directional selection. Expand
Kinship and food availability influence cannibalism tendency in early-instar wolf spiders (Araneae: Lycosidae)
The results suggest that spiders with predominantly solitary lifestyles may bias cannibalism toward non-kin during the juvenile associative period, and that this effect is lost in the subsequent instar. Expand
Cannibalism Regulates Densities of Young Wolf Spiders: Evidence From Field and Laboratory Experiments
The results of field and laboratory experiments lead to the conclusion that cannibalism can act as a strong DD mortality factor for young instars of S. ocreata, with the potential to regulate densities of this abundant cursorial spider. Expand
Kin recognition and cannibalism in a subsocial spider
It is suggested that an ability to avoid cannibalizing kin will favour the evolution of cooperation and group living in phylogenetically pre‐adapted solitary species. Expand
Kin-selected siblicide and cannibalism in the European earwig
This study shows that earwig nymphs recognize kin and adjust their nest-mate killing and cannibalistic behavior as predicted under the hypothesis of kin-selected siblicide and cannibalism. Expand
Investigating how various factors influence cannibalistic tendencies in hatchlings of Pardosa amentata found there was a strong positive relationship between average body mass of the contestants and their latency to cannibalize. Expand
Small within-clutch variance in spiderling body size as a mechanism for avoiding sibling cannibalism in the wolf spider Pardosa pseudoannulata (Araneae: Lycosidae)

The small intraclutch variance in spiderling body size may be understood as a tactic adopted by mother spiders to avoid sibling cannibalism. Expand
Maternal manipulation of hatching asynchrony limits sibling cannibalism in the predatory mite Phytoseiulus persimilis.
It is concluded that P. persimilis mothers increase hatching asynchrony of nearby laid eggs to prevent sibling cannibalism on the last produced offspring. Expand

This review first briefly treats the different types of spider cannibalism and then focuses in more depth on evidence relating cannibalism to population dynamics and food web interactions to address the following questions. Expand
Sex‐dependent effects of sibling cannibalism on life history traits of the ladybird beetle Harmonia axyridis (Coleoptera: Coccinellidae)
The results suggest that sibling cannibalism promotes more rapid development and larger adult size, although the effect was more pronounced in males than in females. Expand
