“…Stevenson and Bryant, 2000). Similarly, this may explain the lack of systematic intraspecific relationships between resting or basal metabolism and reproductive performance reported in many studies in mammals (Hayes et al, 1992;Johnson et al, 2001;Krol et al, 2003;Speakman et al, 2004;Johnston et al, 2007) and birds (Williams and Vézina, 2001) (see also Blackmer et al, 2005). Here we show that the marked inter-individual variation in the adjustment (or 'plasticity') in DEE associated with egg production in female zebra finches is repeatable, i.e.…”

SUMMARYIt is axiomatic that whole-animal metabolism, measured for example as daily energy expenditure (DEE), plays a central role in determining reproductive success and survival (fitness) in all organisms. Nevertheless, strong evidence for consistent systematic relationships between DEE and either individual traits (age, sex, body size), environmental factors (e.g. food availability, temperature) or 'fitness' traits (e.g. number of offspring, survival) remains far from compelling in birds and mammals. Recently, we suggested that female birds might utilise complex, individually variable energy management strategies to meet the metabolic demands of reproduction, generating a wide spectrum of effects on reproductive DEE, from overcompensation (net decrease in DEE) to additive effects (net increase in DEE). Here we show that this individually variable adjustment or 'plasticity' in energy expenditure associated with egg production is repeatable among individuals between successive breeding attempts in female zebra finches (Taeniopygia guttata). Our study highlights the importance (a) of measuring 'plasticity' or change associated with transitions of physiological state (e.g. non-breeding to breeding) based on multiple measurements of the same individual, and (b) of extending consideration of how selection might drive the evolution of phenotypic plasticity per se to include physiological and metabolic traits.

“…Various other measures of quality, for example, longevity or lifetime reproductive success, have been used in previous studies in this and other populations (Espie et al 2004;Blackmer et al 2005;Moyes et al 2006). However, lifetime performance measures are frequently highly correlated (Moyes et al submitted).…”

Individual differences, density dependence and offspring birth traits in a population of red deer

Variation between individuals is an essential component of natural selection and evolutionary change, but it is only recently that the consequences of persistent differences between individuals on population dynamics have been considered. In particular, few authors have addressed whether interactions exist between individual quality and environmental variation. In part, this is due to the difficulties of collecting sufficient data, but also the challenge of defining individual quality. Using a long-established study population of red deer, Cervus elaphus, inhabiting the North Block of the Isle of Rum, and three quality measures, this paper investigates how differences in maternal quality affect variation in birth body mass and date, as population density varies, and how this differs depending on the sex of the offspring and the maternal quality measure used. Significant interactions between maternal quality, measured as a hind's total contribution to population growth, and population density are reported for birth mass, but only for male calves. Analyses using dominance or age at primiparity to define maternal quality showed no significant interactions with population density, highlighting the difficulties of defining a consistent measure of individual quality.

“…Thus, the higher end of temperature preference for the species may reflect increased energetic requirements in proactive individuals with a higher metabolic engine. Interestingly, Blackmer et al (2005) suggested that increased energy requirements in proactive individuals is compensated by swimming behaviour i.e. displacement to warmer places, another component of the energetic repertoire.…”

Summary1. Environmental temperature gradients provide habitat structure in which fish orientate and individual thermal choice may reflect an essential integrated response to the environment. The use of subtle thermal gradients likely impacts upon specific physiological and behavioural processes reflected as a suite of traits described by animal personality. In this study we examine the relationship between thermal choice, animal personality and the impact of infection upon this interaction.2. We predicted that thermal choice in Nile tilapia Oreochromis niloticus reflects distinct personality traits and that under a challenge individuals exhibit differential thermal distribution.

Nile Tilapia were screened following two different protocols: 1) a suite of individual behavioural tests to screen for personality and 2) thermal choice in a custom-built tank with a thermal gradient (T CH tank) ranging from 21 to 33 ºC. A first set of fish were screened for behaviour and then thermal preference and a second set were tested in the opposite fashion; thermal then behaviour. The final thermal distribution of the fish after 48 h was assessed reflecting final thermal preferendum. Additionally, fish were then challenged using a bacterial Streptococcus iniae model infection to assess the behavioural fever response of proactive and reactive fish.4. Results showed that individuals with preference for higher temperatures were also classified as proactive with behavioural tests and reactive contemporaries chose significantly lower water temperatures. All groups exhibited behavioural fever recovering personality-specific thermal preferences after 5 days.5. Our results show that thermal preference can be used as a proxy to assess personality traits in Nile tilapia and it is a central factor to understand the adaptive meaning of animal personality within a population.Importantly, response to infection by expressing behavioural fever overrides personality related thermal choice.
