“…Variation in development rates caused by such internal mechanisms might trade off with offspring quality for a constant temperature (figure 5b), as predicted by the physiological trade-off hypothesis demonstrated in other taxa (Arendt 1997(Arendt , 2003Arendt et al 2001;Billerbeck et al 2001;Brommer 2003;Shine & Olsson 2003). In other words, some of the variation in embryonic period might be caused by the rate of cell growth and proliferation, cell differentiation, organo-and morphogenesis and ontogeny of regulatory systems (e.g.…”

“…Slower embryonic development may allow increased investment in differentiation of specialized cells (e.g. neural systems, immune function) to enhance offspring quality and adult longevity (Ricklefs 1993;Arendt 1997Arendt , 2003Arendt et al 2001;Billerbeck et al 2001;Brommer 2003;Shine & Olsson 2003), and be favoured in species with low adult mortality risk. The positive correlation observed between the length of the incubation period and adult survival probability (Ricklefs 1993;Martin 2002), thus, may reflect enhanced internal mechanisms for survival afforded by slower development, although direct tests of such functional relationships are lacking.…”

Variation in maternal effects and embryonic development rates among passerine species

Embryonic development rates are reflected by the length of incubation period in birds, and these vary substantially among species within and among geographical regions. The incubation periods are consistently shorter in North America (Arizona study site) than in tropical (Venezuela) and subtropical (Argentina) South America based on the study of 83 passerine species in 17 clades. Parents, mothers in particular, may influence incubation periods and resulting offspring quality through proximate pathways, while variation in maternal strategies among species can result from selection by adult and offspring mortality. Parents of long-lived species, as is common in the tropics and subtropics, may be under selection to minimize costs to themselves during incubation. Indeed, time spent incubating is often lower in the tropical and subtropical species than the related north temperate species, causing cooler average egg temperatures in the southern regions. Decreased egg temperatures result in longer incubation periods and reflect a cost imposed on offspring by parents because energy cost to the embryo and risk of offspring predation are both increased. Mothers may adjust egg size and constituents as a means to partially offset such costs. For example, reduced androgen concentrations in egg yolks may slow development rates, but may enhance offspring quality through physiological trade-offs that may be particularly beneficial in longer-lived species, as in the tropics and subtropics. We provide initial data to show that yolks of tropical birds contain substantially lower concentrations of growth-promoting androgens than north temperate relatives. Thus, maternal (and parental) effects on embryonic development rates may include contrasting and complementary proximate influences on offspring quality and deserve further field study among species.

“…Nicieza & Metcalfe 1997;Gagliano & McCormick 2007) and may be an important mechanism for overcoming unfavourable size-based selection during the early life history. However, growth compensation is also known to produce subsequent costs to the individual (Arendt et al 2001), which may offset the advantages of compensatory growth in the long term. The high early mortality of offspring from poor-condition parents is possibly a cost of the compensatory growth exhibited.…”

Parental effects on offspring life histories: when are they important?

Both the parental legacy and current environmental conditions can affect offspring life histories; however, their relative importance and the potential relationship between these two influences have rarely been investigated. We tested for the interacting effects of parental and juvenile environments on the early life history of the marine fish Acanthochromis polyacanthus . Juveniles from parents in good condition were longer and heavier at hatching than juveniles from parents in poor condition. Parental effects on juvenile size were evident up to 29 days post-hatching, but disappeared by 50 days. Offspring from good condition parents had higher early survival than offspring from poor-condition parents when reared in a low-food environment. By contrast, parental condition did not affect juvenile survival in the high-food environment. These results suggest that parental effects on offspring performance are most important when poor environmental conditions are encountered by juveniles. Furthermore, parental effects observed at hatching may often be moderated by compensatory mechanisms when environmental conditions are good.

“…In fishes, a fast growing strain of pumpkinseed sunfish (Lepomis gibbosus) had a delayed onset of mineralization in their cranial bones relative to a slow growing strain [37] . Further study found a negative correlation between scale strength (in terms of ability to resist being pierced) and growth rate that was consistent both within and among populations using pumpkinseed from six populations known to differ in their intrinsic growth rates [38] . This trade-off between growth rate and scale strength may have fitness consequences in terms of likelihood of surviving predation attempts or swimming efficiency.…”

Rapid growth cost in “all-fish” growth hormone gene transgenic carp: Reduced critical swimming speed

Evidence has accumulated that there is a trade-off between benefits and costs associated with rapid growth. A trade-off between growth rates and critical swimming speed (U crit ) had been also reported to be common in teleost fish. We hypothesize that growth acceleration in the F 3 generation of "all-fish" growth hormone gene (GH) transgenic common carp (Cyprinus carpio L.) would reduce the swimming abilities. Growth and swimming performance between transgenic fish and non-transgenic controls were compared. The results showed that transgenic fish had a mean body weight 1.4-1.9-fold heavier, and a mean specific growth rate (SGR) value 6%-10% higher than the controls. Transgenic fish, however, had a mean absolute U crit (cm/s) value 22% or mean relative U crit (BL/s) value 24% lower than the controls. It suggested that fast-growing "all-fish" GH-transgenic carp were inferior swimmers. It is also supported that there was a trade-off between growth rates and swimming performance, i.e. faster-growing individuals had lower critical swimming speed.transgenic fish, growth, swimming performance, trade-off, growth hormone, critical swimming speedSince the first successful case of transgenic fish was achieved [1] , transgenic technology has made great advance in fish, and fish may be considered the best candidate for the first marketable transgenic animal for human consumption [2,3]
