“…Color-banding studies provided much of the data presented here and such studies where investigators intensively band and look for individuals may yield high recapture probabilities and reasonable estimates of survival. Indeed, survival estimates from Jolly-Seber (Cormack 1964, Jolly 1965, Seber 1965) models, which take recapture probabilities into account, did not differ from estimates under other methods when compared among nest sites and migratory classifications (Martin 1993b ), suggesting that estimates are reasonable relative to the broad ecological comparisons made here. Any biases that do exist should simply increase statistical noise and reduce the strength of relationships.…”

“…When the first year after capture, or any single calendar year, differed dramatically in comparison to all remaining years, it was excluded from estimates. Survival values calculated by methods other than Farner's method (e.g., Roberts 1971; or the method derived jointly by Jolly [1965] and Seber [1965]) were taken as directly reported by authors. Some studies had supplemental food and these were excluded whenever additional estimates were available for other populations of the same species without supplemental food.…”

Abstract. Food limitation is generally thought to underlie much of the variation in life history traits of birds. I examined variation and covariation of life history traits of 123 North American Passeriformes and Piciformes in relation to nest sites, nest predation, and foraging sites to examine the possible roles of these ecological factors in life history evolution of birds. Annual fecundity was strongly inversely related to adult survival, even when phylogenetic effects were controlled. Only a little of the variation in fecundity and survival was related to foraging sites, whereas these traits varied strongly among nest sites. Interspecific differences in nest predation were correlated with much of the variation in life history traits among nest sites, although energy trade-offs with covarying traits also may account for some variation. For example, increased nest predation is associated with a shortened nestling period and both are associated with more broods per year, but number of broods is inversely correlated with clutch size, possibly due to an energy trade-off. Number of broods was much more strongly correlated with annual fecundity and adult survival among species than was clutch size, suggesting that clutch size may not be the primary fecundity trait on which selection is acting. Ultimately, food limitation may cause trade-offs between annual fecundity and adult survival, but differences among species in fecundity and adult survival may not be explained by differences in food abundance and instead represent differing tactics for partitioning similar levels of food limitation. Variation in fecundity and adult survival is more clearly organized by nest sites and more closely correlated with nest predation; species that use nest sites with greater nest predation have shorter nestling periods and more broods, yielding higher fecundity, which in turn is associated with reduced adult survival.Fecundity also varied with migratory tendencies; short-distance migrants had more broods and greater fecundity than did neotropical migrants and residents using similar nest sites. However, migratory tendencies and habitat use were confounded, making separation of these two effects difficult. Nonetheless, the conventional view that neotropical migrants have fewer broods than residents was not supported when nest site effects were controlled.

“…We used an open‐population, time‐dependent Cormack–Jolly–Seber model (Cormack, 1964; Jolly, 1965; Seber, 1965) implemented in the program MARK (Cooch & White, 2014; White & Burnham, 1999) to determine the annual return rate of nesting adult smallmouth bass and thus infer potential sex‐specific differences in the cost of reproduction. The data consisted of marked and unmarked individuals (based on their multilocus genotype) captured during successive spawning seasons [three seasons (2012–2014) for females; four seasons (2011–2014) for males] and were represented as individual capture histories.…”

Genetic mating system and mate selection in smallmouth bass

Mating systems are an important factor influencing the variance in reproductive success among individuals within natural populations and thus have important ecological and evolutionary implications. We used molecular pedigree reconstruction techniques with microsatellite DNA data to characterize the genetic mating system and mate selection in adult smallmouth bass spawning in Lake Opeongo. The genetic mating system of smallmouth bass in this system can be characterized as predominantly monogamous with a low rate of polygynandry particularly among larger individuals. Iteroparous individuals showed a complete absence of interannual mate fidelity, presumably due to the low annual return rate of spawning adults. Within a season, individuals from both sexes pursued additional mating opportunities with males showing greater variance in mate number than females. Female mate selection appeared to be largely random with little evidence for elevated levels of inbreeding in this population. Multiple mating females pursued additional males to whom they were less related than the first male with which they spawned within a given season, however, this pattern varied among years. The mating pattern observed in this population would likely limit the strength of sexual selection and thus could account for the lack of sexual dimorphism and the absence of alternative reproductive tactics in this species.

“…The POPAN model (Schwarz & Arnason 1996, Arnason & Schwartz 1999, a derivative of the Jolly-Seber model (Jolly 1965, Seber 1965, estimates N S , defined as the total number of individuals that are ever exposed to capture between the first and last survey occasions, comprising individuals that join the population between the first and last surveys in addition to individuals present at the start of the first survey. A proportion of the N S enters the survey area during each survey occasion and is available for capture: this is estimated by a parameter termed the probability of entry for each survey occasion.…”
