Data for: Predicting age and mass at maturity from feeding behavior and diet in M. sexta: An empirical test of a life history model
<p>Feeding for most animals involves bouts of active ingestion alternating with bouts of no ingestion. In insects, the temporal patterning of bouts varies widely with resource quality and is known to affect growth, development time, and fitness. However, the precise impacts of resource quality and feeding behavior on insect life history traits is poorly understood. To explore and better understand the connections between feeding behavior, resource quality and insect life history traits, we combined laboratory experiments with a recently proposed mechanistic model of insect growth and development for a larval herbivore, <em>Manduca sexta</em>. We ran feeding trials for 4<sup>th</sup> and 5<sup>th</sup> instar larvae across different diet types (two hostplants and artificial diet) and used these data to parameterize a joint model of age and mass at maturity that incorporates both insect feeding behavior and hormonal activity. We found that the estimated durations of both feeding and non-feeding bouts were significantly shorter on low- than on high-quality diets. We then explored how well the fitted model predicted historical out-of-sample data on age and mass of <em>M</em>.<em> sexta</em>. We found that the model accurately described qualitative outcomes for the out-of-sample data, notably that a low-quality diet results in reduced mass and later age at maturity compared to high-quality diets. Our results clearly demonstrate the importance of diet quality on multiple components of insect feeding behavior (feeding and non-feeding), and partially validate a joint model of insect life history. We discuss the implications of these findings with respect to insect herbivory and discuss ways in which our model could be improved or extended to other systems.</p>
Age, but not an immune challenge, triggers terminal investment in the Pacific field cricket
<p>The terminal investment hypothesis proposes that, when individuals are faced with a threat to survival, they will increase investment in current reproduction. The level of the threat necessary to elicit terminal investment (the dynamic terminal investment threshold) may vary based on other factors that also influence future reproduction. Here, we tested whether there is an interactive effect of age and an immune challenge on the dynamic terminal investment threshold in the Pacific field cricket, <em>Teleogryllus</em> <em>oceanicus</em>. We measured the courtship call, mating attractiveness, ejaculate size and offspring production of <em>T. oceanicus</em> males. We found only limited support for the dynamic terminal investment threshold: there was no consistent evidence of a positive interaction between male age and immune challenge intensity. However, we found evidence for age-related terminal investment: older males produced a larger spermatophore than younger males. Older males also had a slower calling rate compared to younger males, suggesting a potential trade-off between these two pre- and post-copulatory traits. As some, but not, all reproductive traits responded plastically to cues for terminal investment, our research highlights the importance of considering a broad range of pre-and post-copulatory traits when exploring the potential for terminal investment to occur.</p>

Effects of brain maintenance and cognitive reserve on age-related decline in three cognitive abilities
<p><strong>Objectives </strong></p> <p>Age-related cognitive changes can be influenced by both brain maintenance (BM), which refers to the relative absence over time of changes in neural resources or neuropathologic changes, and cognitive reserve (CR), which encompasses brain processes that allow for better-than-expected behavioral performance given the degree of life-course related brain changes. This study evaluated the effects of age, BM, and CR on longitudinal changes over two visits, 5 years apart, in three cognitive abilities that capture most of age-related variability.</p> <p><strong>Method </strong></p> <p>Participants included 254 healthy adults aged 20–80 years at recruitment. Potential BM was estimated using whole brain cortical thickness and white matter mean diffusivity at both visits. Education and IQ (estimated with AMNART) were tested as moderating factors for cognitive changes in the three cognitive abilities.</p> <p><strong> Results </strong></p> <p>Consistent with BM—after accounting for age, sex, and baseline performance—individual differences in the preservation of mean diffusivity and cortical thickness were independently associated with relative preservation in the three abilities. Consistent with CR—after accounting for age, sex, baseline performance, and structural brain changes—higher IQ, but not education, was associated with reduced 5-year decline in Reasoning (𝛽=0.387, p=0.002), and education was associated with reduced decline in Speed (𝛽=0.237, p=0.039). <strong> </strong></p> <p><strong>Discussion</strong></p> <p>These results demonstrate that both CR and BM can moderate cognitive changes in healthy aging and that the two mechanisms can make differential contributions to preserved cognition.</p>
Female reproductive fluids 'rescue' sperm from phenotypic ageing in an external fertilizer
<p class="MsoNormal">Female reproductive fluids (FRF) serve key reproductive functions in sexually reproducing animals, including modifying the way sperm swim and detect eggs, and influencing sperm lifespan. Despite the central role of FRF during fertilisation, we know surprisingly little about sperm-FRF interactions under different environmental conditions. Theory suggests that, in external fertilisers, FRF may 'rescue' sperm from ageing effects as they search to fertilise eggs. Here, we test the interaction between these two fundamental properties of the fertilisation environment, ejaculate age (i.e., time since ejaculation) and FRF, on a range of functional sperm phenotypes in a broadcast spawning mussel, <em>Mytilus galloprovincialis</em>. We found that the effects of ejaculate age on multivariate sperm motility traits and total sperm motility were altered by FRF, and that longer-lived sperm exhibit stronger, likely more advantageous, responses to FRF after periods of ageing. We also detected significant among-male variation in the relationship between sperm motility traits and ejaculate age; notably, these patterns were only revealed when sperm encountered FRF. Collectively these findings underscore the importance of considering female reproductive physiology when interpreting ageing-related declines in sperm motility, as doing so may expose important sources of variation in sperm phenotypic plasticity among males and environments.</p>
On ageing and age-specific effects of spontaneous mutations
<p>Evolutionary theories of ageing assume causal mutations either have beneficial early-life effects which gradually become deleterious with advancing age (antagonistic pleiotropy: AP) or mutations that only have deleterious effects at old age (mutation accumulation: MA). Mechanistically, ageing is predicted to result from damage accumulating in the soma. While this scenario is compatible with AP, it is not immediately obvious how damage would accumulate under MA. In a modified version of the MA theory, it has been suggested that mutations with weakly deleterious effects at young age can also contribute to ageing, if they generate damage that gradually accumulates with age. Mutations with increasing deleterious effects have recently gained support from theoretical work and studies of large-effect mutations. Here we address if spontaneous mutations also have negative effects that increase with age. We accumulate mutations with early-life effects in <em>Drosophila</em> <em>melanogaster</em> across 27 generations and compare their relative effects on fecundity early and late in life. Our mutation accumulation lines on average have substantially lower early-life fecundity compared to controls. These effects were further maintained throughout life, but they did not increase with age. Our results thus suggest that most spontaneous mutations do not contribute to damage accumulation and ageing.</p>
Figure 13 in Metal-Age Maritime Culture at Jareng Bori Rockshelter, Pantar Island, Eastern Indonesia
Figure 13. Rim sherds illustrating the range of straight, incurving, and out-curving rims at Jareng Bori. With the exception of the incurving notched pie-crust lip (844), out-curving rims (Surface) with wide flat lips (824, 2691) and inverted rims (841, 828), the fragmentary nature of the assemblage prevents further identification of vessel forms.
