“…This process may be repeated as many as 9 times in a single season in freshwater populations (Wootton and Fletcher, 2009;JA Baker, personal observation), although oceanic populations appear to produce many fewer, though larger, clutches (Boule and FitzGerald, 1989;Dufresne et al, 1990;RW King, personal observation). Clutch size mirrors reproductive effort in threespine stickleback (Baker et al, 1998Wootton and Fletcher, 2009), with population-level correlations between these traits ranging from 0.79 to 0.90 (N = 83 populations; JA Baker, unpublished data).…”

Life-history plasticity in female threespine stickleback

The postglacial adaptive radiation of the threespine stickleback fish (Gasterosteus aculeatus) has been widely used to investigate the roles of both adaptive evolution and plasticity in behavioral and morphological divergence from the ancestral condition represented by present-day oceanic stickleback. These phenotypes tend to exhibit high levels of ecotypic differentiation. Population divergence in life history has also been well studied, but in contrast to behavior and morphology, the extent and importance of plasticity has been much less well studied. In this review, we summarize what is known about life-history plasticity in female threespine stickleback, considering four traits intimately associated with reproductive output: age/size at maturation, level of reproductive effort, egg size and clutch size. We envision life-history plasticity in an iterative, ontogenetic framework, in which females may express plasticity repeatedly across each of several time frames. We contrast the results of laboratory and field studies because, for most traits, these approaches give somewhat different answers. We provide ideas on what the cues might be for observed plasticity in each trait and, when possible, we inquire about the relative costs and benefits to expressed plasticity. We end with an example of how we think plasticity may play out in stickleback life history given what we know of plasticity in the ancestor.

“…It is also possible that differences in age at the time of sampling affected our biochemical measurements, as some F1 fish were up to 6months older than F2 fish when these traits were measured (up to 1year and 6-9months of age versus 1year and 3-4months of age). In particular, the higher mitochondrial enzyme activities (CS and COX) in the pectoral muscles of F2 fish when compared with F1 fish may be due to senescence in the older F1 fish, as CS activity is known to decline in axial muscles by 2years of age in migratory marine sticklebacks (Dufresne et al, 1990;Guderley et al, 2001).…”

SUMMARYDetermining which underlying traits contribute to differences in whole-animal performance can be difficult when many traits differ between individuals with high and low capacities. We have previously found that migratory (anadromous marine) and nonmigratory (stream-resident) threespine stickleback (Gasterosteus aculeatus) populations have genetically based differences in prolonged swimming performance (U crit ) that are associated with divergence of a number of candidate morphological and physiological traits (pectoral fin size and shape, body shape, pectoral muscle and heart size, and pectoral muscle metabolic enzyme activities). Here, we use F2 hybrid crosses to determine which traits are correlated with U crit when expressed in a largely randomized genetic background and a range of trait values for other divergent traits. We found that four of our 12 candidate traits were positively correlated with U crit in F2 hybrids and that the combined effects of ventricle mass, pectoral adductor mass and adductor citrate synthase activity accounted for 17.9% of the variation in U crit . These data provide additional support for a causal role of muscle and heart size in mediating intraspecific differences in U crit , but indicate that many candidate morphological and biochemical traits do not have a strong effect on U crit when disassociated from other divergent traits. However, the limited variation in U crit in our F2 hybrid families may have decreased our ability to detect correlations among these candidate traits and U crit . These data suggest that many traits, interactions among traits and traits not measured in this study affect prolonged swimming performance in threespine stickleback.

“…First, any pattern of allocation is subject to the trade-off between present and future reproduction (Williams 1966) and second, allocation choices are based on the 'trinity of growth, maintenance and reproduction' (Reznick & Braun 1987). Since parental care in fish imposes energetic costs (Chellappa et al 1989, Fitzgerald et al 1989, Dufresne et al 1990, Coleman & Fischer 1991, then the availability of food to fish during the parental care period should play an important role in the behaviourial and energetic effort that parents devote to both present and future reproduction (Hirshfield 1980, Lamon & Ward 1983.…”

The effects of supplemental food on reproduction in parental male smallmouth bass

We provided supplemental food for parental male smallmouth bass, Micropterus dolomieu, to determine if food supply limits the reproductive performance of nesting males as measured by care duration, reproductive success and survival of adult males. Although supplementing the diet of parental males had a positive effect on all three reproductive measures, the experiment generated contrasting results in different years. In the first year, supplemental feeding only improved the survival of fed males versus unfed males. In the second year, supplemental feeding increased care duration and reproductive success of fed males but reduced their survival relative to unfed males. Our supplemental feeding improved current or future measures of reproductive performance, but not both simultaneously. The results appear to demonstrate phenotypic plasticity in the extent to which energy from supplemental feeding can be allocated to present or future reproduction.
