“…Annual fluctuations of northern rodent populations are unimodal and are characterized by winter and spring declines, summer increases, and autumn peaks in abundance (Alibhai and Gipps 1985;Falls et al 2007;Flowerdew 1985). The unimodal pattern of seasonal abundance was in part ascribed to the autumn and winter deceases and summer increases in survival, reproduction, and recruitment in other rodents (Falls et al 2007;Jacquot and Vessey 1998;Rintamaa et al 1976). The gerbil population in our study also exhibited a unimodal pattern of abundance but peaked relatively early (Fig.…”

“…Finally, income breeding may occur in short‐lived species that are not able to delay reproduction even if current food resources are scarce (e.g. low RRV; Williams, 1966), such as white‐footed mice, Peromyscus leucopus (Jacquot & Vessey, 1998). Therefore, short‐lived income breeders that experience a poor food year may exhibit significant declines in fecundity.…”

Snakes allocate amino acids acquired during vitellogenesis to offspring: are capital and income breeding consequences of variable foraging success?

Reproductive allocation strategies have been historically described as lying on a continuum between capital and income breeding. Capital breeders have been defined as species that allocate stored reserves to reproduction, whereas income breeders have been defined as species that allocate relatively recently‐ingested food resources to reproduction. Snakes are considered capital breeders because they efficiently store large amounts of nutrients and energy, potentially enough to support an entire reproductive bout without feeding. We examined the abilities of five viviparous snake species to allocate income to follicles during vitellogenesis. We fed 15N‐labelled L‐leucine to experimental females of each species during vitellogenesis, whereas control females were fed unlabelled meals. After ovulation, we measured yolk 15N p.p.m. using mass spectrometry. Maternal scale samples taken before labelling were used to estimate endogenous 15N concentrations, which should represent ‘capital’. Scale samples taken at ovulation were used to determine whether snakes assimilated 15N‐labelled‐leucine from labelled diets. Yolks and post‐ovulatory scales of labelled females were significantly more enriched in 15N than those of unlabelled females in all species, indicating significant assimilation and allocation of income‐derived amino acids to the yolk during vitellogenesis. The lack of among‐species differences suggests that all species allocated income amino acids to vitellogenesis. The results obtained in the present study suggest that proportional utilization of income or capital depends on the frequency and timing of foraging success during reproductive events. Therefore, capital and income breeding may be consequences of both life‐history and environmental constraints on foraging success, rather than strategies of reproductive allocation. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, 106, 390–404.

“…Despite the relevance of fitness at first reproduction, young novice females generally wean fewer, smaller offspring than do older, more experienced females (Clutton-Brock 1991; but see Jacquot and Vessey 1998). The trade-offs between current and future reproductive success (Williams 1966) and between growth and reproduction (Millar 1975;Tuomi et al 1983) are life-history concepts that provide a theoretical basis for the relatively low performance of first-time breed-ers.…”

“…The trade-offs between current and future reproductive success (Williams 1966) and between growth and reproduction (Millar 1975;Tuomi et al 1983) are life-history concepts that provide a theoretical basis for the relatively low performance of first-time breed-ers. However, both trade-offs may be of only minor importance in species that increase energy intake to compensate for the energy requirements of reproduction (income breeders) and have high extrinsic mortality rates (Hare and Murie 1992;Kozlowski 1992;Jacquot and Vessey 1998). Both apply to most small mammals.…”

Does primiparity affect the efficiency of converting energy to offspring production in the guinea-pig?

In small mammals the reproductive performance of first-time breeders is of great relevance to fitness. However, young primiparous mothers reproduce generally less successfully than multiparous ones. One constraining factor may be inefficiency of novice breeders in converting energy to offspring production. To test this hypothesis I investigated the energy cost of gestation and lactation in the guinea-pig (Cavia porcellus). I compared mothers' offspring production (growth of pups), body mass, and energy intake, as well as the solid-food intake of their pups (during lactation) and energy expenditure (resting oxygen consumption) between young primiparous, old primiparous, secondlitter multiparous, and third-litter multiparous females. Young primiparous females showed significantly lower offspring production than multiparous females. For older primiparous females the level was intermediate. Both young and older primiparous females showed a lower efficiency of converting energy to offspring production than their multiparous conspecifics. Parity affected lactation most strongly. Part of the inefficiency of primiparous guinea-pig mothers can be explained by the lower contribution to the energy budget made by their offspring from independent consumption of solid food.Résumé : Chez les petits mammifères, la performance au cours de la première reproduction est d'une grande importance par son effet sur le fitness. Cependant, les jeunes femelles primipares ont généralement un succès reproducteur inférieur à celui des femelles multipares. L'un des facteurs restrictifs auxquels on peut penser est l'inefficacité des femelles inexpérimentées à consacrer leur énergie à la production d'une progéniture. Pour éprouver cette hypothèse, j'ai tenté de déterminer les coûts énergétiques reliés à la gestation et à l'allaitement chez le Cochon d'Inde (Cavia porcellus). J'ai comparé la production maternelle (croissance des petits), la masse corporelle, la consommation d'énergie des femelles, la consommation d'aliments solides de leurs petits (au cours de l'allaitement) et la dépense énergétique (consommation d'oxygène au repos) chez des jeunes femelles primipares, des vielles femelles primipares, des femelles multipares à leur deuxième portée, et des femelles multipares à leur troisième portée. Les jeunes femelles primipares ont un succès reproducteur significativement moindre que le femelles multipares. Les vieilles femelles primipares ont un succès intermédiaire. Les mères primipares jeunes ou vieilles ont une efficacité de conversion de leur énergie à la production d'une progéniture inférieure à celle des femelles multipares. C'est à l'allaitement que les femelles primipares et les femelles multipares se distinguent le plus. Une partie de l'inefficacité reproductrice enregistrée chez les femelles primipares peut s'expliquer par la contribution moins importante de leurs petits au budget énergétique par consommation de nourriture solide.[Traduit par la Rédaction] 306 Künkele Can.
