“…Genetic analyses of survival have typically supported this assumption by finding little evidence of genetic variation from diverse taxonomic groups both in farmed (e.g., Van Arendonk et al 1996;Knol et al 2002;Goyache et al 2003;Casellas et al 2007) and in wild animals (e.g., Futuyma et al 1995;Campbell 1997). However, in some instances moderate to high heritabilities for survival have also been found (e.g., Robison and Luempert 1984;Ernande et al 2004;Kenway et al 2006). Even with fairly low heritability of survival, animal breeding programs have produced slow but significant long-term genetic improvement in survival, contributing to increased animal welfare and economic profitability (Knol et al 2002;Goyache et al 2003).…”

As a fitness trait, survival is assumed to exhibit low heritability due to strong selection eroding genetic variation and/or spatio-temporal variation in mortality agents reducing genetic and increasing residual variation. The latter phenomenon in particular may contribute to low heritability in multigeneration data, even if certain cohorts exhibit significant genetic variation. Analysis of survival data from 10 year classes of rainbow trout reared at three test stations showed that treating survival as a single trait across all generations resulted in low heritability (h 2 ¼ 0.08-0.17). However, when heritabilities were estimated from homogeneous generation and test station-specific cohorts, a wide range of heritability values was revealed (h 2 ¼ 0.04-0.71). Of 64 genetic correlations between different cohorts, 20 were positive, but 16 were significantly negative, confirming that genetic architecture of survival is not stable across generations and environments. These results reveal the existence of hidden genetic variation for survival and demonstrate that treating survival as one trait over several generations may not reveal its true genetic architecture. Negative genetic correlations between cohorts indicate that overall survival has limited potential to predict general resistance, and care should be taken when using it as selection criterion.

“…Genetic improvement programmes can increase the economic efficiency of farmed shrimp (Argue, Arce, Lotz & Moss ; Pérez‐Rostro & Ibarra ,b; Gitterle, Rye, Salte, Cock, Johansen, Lozano, Suárez & Gjerde ; Gitterle, Salte, Gjerde, Cock, Johansen, Salazar, Lozano & Rye ; Castillo‐Juárez, Casares, Campos‐Montes, Villela, Ortega & Montaldo ; Andriantahina, Liu & Huang ; Campos‐Montes, Montaldo, Martínez‐Ortega, Jiménez & Castillo‐Juárez ).

The aim of this study was to estimate heterosis and heritability for harvest body weight of the Pacific white shrimp (Litopenaeus vannamei) measured at commercial farm conditions. Heterosis and heritability were estimated using a base population from diallel crosses of eight introduced strains. The base population included 9936 shrimp from 207 families that were produced with 188 sires and 172 dams using a nested mating design by artificial insemination. Heterosis was calculated basing on the least squares means (LSM) of harvest body weight. The results showed that most of the hybrids (75%) have positive heterosis for harvest body weight, which ranged from À13.36% (UA2 9 UA5) to 13.80% (UA6 9 UA5) with a mean of 2.41%. The high amount of heterosis manifested in the hybrids indicated the usefulness of these hybrids for improving the growth. Variance components and heritability for harvest body weight were estimated using an animal model. The heritability estimate for harvest body weight was 0.092 AE 0.082 (h 2 ) when genetic groups were excluded from the pedigree, but it was decreased when genetic groups were included in the pedigree (h 2 group = 0.066 AE 0.050), implying that there are strain additive genetic effect and heterosis in the base population. However, the heritability estimates for harvest body weight were significantly different from zero (P < 0.05) and there was no significant difference between h 2 and h 2 group (P > 0.05). The results from this study indicated that significant improvement for growth is possible through crossbreeding and selective breeding in L. vannamei.

“…Given this, the strong direct relationship between cohort-level adult survival probabilities of fostered nestlings and the breeding adults in their birth colony-but no such relationship with the breeding adults in their foster colony-implies a heritable basis for adult survival in cliff swallows. While significant heritabilities for survival have been reported in a few organisms (Chambers et al 1996;Campbell 1997;Kenway et al 2006;Blomquist 2010;Dégremont et al 2010), these are the first data for a colonial species suggesting heritable parent-offspring resemblance in survival.…”

“…However, various factors can, at least in theory, maintain moderate levels of additive genetic variance for fitness-related traits, including polygenic mutation, spatiotemporally fluctuating selection, and negative correlations between fitness components (Mousseau and Roff 1987;Fuiman and Cowan 2003;Coltman et al 2005;Vehviläinen et al 2008). Perhaps as a result, some empirical studies have provided evidence that survival can have a moderately high heritability and thus be subject to selection (Chambers et al 1996;Campbell 1997;Kenway et al 2006;Blomquist 2010;Dégremont et al 2010).…”

Parent–offspring resemblance in colony-specific adult survival of cliff swallows

Survival is a key component of fitness. Species that occupy discrete breeding colonies with different characteristics are often exposed to varying costs and benefits associated with group size or environmental conditions, and survival is an integrative net measure of these effects. We investigated the extent to which survival probability of adult (C1-year old) cliff swallows (Petrochelidon pyrrhonota) occupying different colonies resembled that of their parental cohort and thus whether the natal colony had long-term effects on individuals. Individuals were cross-fostered between colonies soon after hatching and their presence as breeders monitored at colonies in the western Nebraska study area for the subsequent decade. Colony-specific adult survival probabilities of offspring born and reared in the same colony, and those cross-fostered away from their natal colony soon after birth, were positively and significantly related to subsequent adult survival of the parental cohort from the natal colony. This result held when controlling for the effect of natal colony size and the age composition of the parental cohort. In contrast, colony-specific adult survival of offspring cross-fostered to a site was unrelated to that of their foster parent cohort or to the cohort of non-fostered offspring with whom they were reared. Adult survival at a colony varied inversely with fecundity, as measured by mean brood size, providing evidence for a survival-fecundity trade-off in this species. The results suggest some heritable variation in adult survival, likely maintained by negative correlations between fitness components. The study provides additional evidence that colonies represent non-random collections of individuals.
