“…Indeed, previous work suggests that a range of factors are likely to affect and favour the evolution of filial cannibalism (Manica 2002;Payne et al 2002;Neff 2003;Klug & Bonsall 2007). For example, both parental condition and density-dependent egg survival affect filial cannibalism in the sand goby (Klug et al 2006).…”

“…Previous studies have highlighted the potential importance of selective filial cannibalism (i.e. in relation to the consumption of unfertilized or diseased eggs: Mrowka 1987, Kraak 1996; cannibalism of nonkin after cuckolding : Neff 2003), and recent theoretical work suggests that the ability to cannibalize offspring selectively in relation to offspring phenotype (e.g. expected survivorship, maturation rate) can directly favour the evolution of filial cannibalism (Klug & Bonsall 2007).…”

Filial cannibalism (the consumption of one's own offspring) is thought to represent an adaptive strategy in many animals. However, little is known about the details of which offspring are consumed when a parent cannibalizes. Here, we examined patterns of within-brood filial cannibalism in the sand goby ( Pomatoschistus minutus ). Males spawned sequentially with two females, and we asked whether males cannibalized selectively with regard to egg size or the order in which eggs were received. Males preferentially consumed the larger eggs of the second female they spawned with. Because larger eggs took longer to hatch, and because female 2's eggs were up to 1 day behind those of female 1, such preferential cannibalism might allow males to decrease the time spent caring for the current brood and re-enter the mating pool sooner. More work is needed to understand the fitness consequences of such selective cannibalism.

“…While group-living alloparents may increase their inclusive fitness by helping relatives (Hamilton 1963(Hamilton , 1964aConrad et al 1998;Griffin and West 2003;Eberle and Kappeler 2006;see also discussion in Clutton-Brock 2002), examination of the role of kin selection in nongroup-living alloparents has typically focused on parental response to specific young (e.g., Bukacinski et al 2000;Neff 2003;Green et al 2008) or how young respond to relatedness among them (e.g., Hain and Neff 2009). Additionally, subordinate alloparenting in group-living species is typically associated with restrictions on the necessary resources needed for independent breeding (e.g., few suitable nest sites ;Emlen 1991;Hatchwell and Komdeur 2000), and benefits to alloparents usually include residency and eventual reproduction at the territory (usually after a considerable time delay; Emlen 1991).…”

Adoption and cuckoldry lead to alloparental care in the tessellated darter (Etheostoma olmstedi), a non-group-living species with no evidence of nest site limitation

While extensive empirical and theoretical work has focused on the evolution of costly cooperation (particularly in group-living species), less attention has been paid to more low-risk or immediately beneficial forms of cooperation. In some non-group-living darters, alloparental care (or allocare) by subordinates has been noted to result from by-product benefits as small territorial (subordinate) males adopt and provide care to the abandoned eggs of large territorial (dominant) males. In the tessellated darter (Etheostoma olmstedi), allocare also results from sneak fertilization. However, information on the rate of allocare by tessellated darters is contradictory: prior behavioral work suggested that it is very common, while a genetic examination showed males to primarily care for their own young. We found behavioral and genetic evidence of very high levels of allocare at our study location. The relative size of the assigned fathers of young to the alloparental male is consistent with the idea that initial allocare primarily results from sneak fertilization ("cuckoldrybased allocare"), but later allocare results from subordinate males caring at previously abandoned nests ("adoption-based allocare"). Larger males appeared to breed more frequently at different nests, but did not father more individual offspring than smaller males. Finally, low relatedness between abandoning and alloparenting males suggests that kin selection does not contribute to alloparental care. We discuss how variation in nest availability may explain the inconsistent findings of the rate of alloparental care in the tessellated darter, and how increased research in this and similar systems can expand our understanding of the evolution of cooperation.

“…3). To some extent, this result is surprising since a large number of studies have found that small clutches are more likely than larger clutches to be fully cannibalized by the caring male -in sand gobies and other species (e.g., Schwanck 1986;Petersen and Marchetti 1989;Petersen 1990;Forsgren et al 1996;Kvarnemo et al 1998;Manica 2002bManica , 2004Lissåker et al 2003;Neff 2003;Lissåker and Kvarnemo 2006). In fact, even the large females did not achieve a combined brood size that was large enough to be "safe", when they chose to lay their eggs in the nest with the small initial clutch.…”

Filial cannibalism in a nest-guarding fish: females prefer to spawn in nests with few eggs over many

In fish, fecundity correlates with female body size and egg-tending males often eat small broods. Therefore, small females may prefer to spawn in nests that already contain many eggs, to ensure the brood is as large as possible.In contrast, large females may prefer nests with few eggs, if high egg number or density has a negative effect on egg survival, or if there are drawbacks of spawning last in a nest. To test the hypothesis that female body size affects nest (and male mate) choice, using the sand goby (Pomatoschistus minutus), we allowed small and large females to choose between two males that were matched in size -one guarding a small clutch and the other a large clutch, respectively. We recorded where females spawned (measure of female preference), the combined brood size, male courtship, egg care and nest building. We also quantified the effect of brood size and egg density on egg survival in a separate data set. Although the combined broods did not exceed the small brood sizes that are at risk of being eaten, both small and large females preferred to spawn in nests with smaller clutch sizes. This preference could not be explained by more courtship or male parental effort, nor by reduced survival of larger or denser broods. Instead, our result might be explained by females avoiding the danger of cannibalism of young eggs by males or the risk of reduced egg health associated with being near the nest periphery.
