Abstract
Understanding the factors that augment optimal health during aging is critical as the US older adult population is increasing. Most research about food insecurity, nutritional risk, and perceived health among older adults are in urban areas or congregate living facilities. Thus, the purpose of this project was to study the relationships among these factors, plus activities of daily living, in community-dwelling older adults in a medium-sized city. Using a qualitative-quantitative study design, a cross-sectional survey was completed by 167 low-income senior apartment residents. Food insecurity in this group was higher than the national and state rate, yet nutrition assistance programs were underutilized and participants under 75 years were more food insecure than their older counterparts. Food insecure residents were at greater nutritional risk, had poorer self-reported health status, were more likely to be depressed, and had a less independent function, including limitations on the ability to shop for and prepare food. The study area is desirable to retirees due to lower cost of living; however, access to services, such as grocery stores, public transportation, and health care providers is limited. This research indicates the need for increased outreach, nutrition assistance, and support services to ensure healthy aging in these regions.

Abstract
Declines in animal body sizes are widely reported and likely impact ecological interactions and ecosystem services. For harvested species subject to multiple stressors, limited understanding of the causes and consequences of size declines impedes prediction, prevention, and mitigation. We highlight widespread declines in Pacific salmon size based on 60 years of measurements from 12.5 million fish across Alaska, the last largely pristine North American salmon-producing region. Declines in salmon size, primarily resulting from shifting age structure, are associated with climate and competition at sea. Compared to salmon maturing before 1990, the reduced size of adult salmon after 2010 has potentially resulted in substantial losses to ecosystems and people; for Chinook salmon we estimated average per-fish reductions in egg production (-16%), nutrient transport (-28%), fisheries value (-21%), and meals for rural people (-26%). Downsizing of organisms is a global concern, and current trends may pose substantial risks for nature and people.

Abstract
BACKGROUND There is limited research in young infants, particularly <3 months of age, on maternal feeding practices in spite of increasing evidence that early weight gain velocity is a determinant of later obesity risk. OBJECTIVE To examine associations between maternal executive function (cognitive control over one's own behaviour), maternal feeding decisions and infant weight and adiposity gains. METHODS We used a checklist to assess cues mothers use to decide when to initiate and terminate infant feedings at 2 weeks and 3 months of age (N = 69). Maternal executive function was assessed using the NIH Toolbox Cognition Battery subtests for executive function and infant body composition using air displacement plethysmography. RESULTS Mothers with higher executive function reported relying on fewer non-satiety cues at 2 weeks of age (β = -0.29, p = 0.037) and on more infant hunger cues at 3 months of age (β = 0.31, p = 0.018) in their decisions on initiating and terminating feedings. Responsive feeding decisions, specifically the use of infant-based hunger cues at 3 months, in turn were associated with lower gains in weight-for-length (β = -0.30, p = 0.028) and percent body fat (β = -0.2, p = 0.091; non-covariate adjusted β = -0.27, p = 0.029). CONCLUSIONS These findings show both an association between maternal executive function and responsive feeding decisions and an association between responsive feeding decisions and infant weight and adiposity gains. The causal nature and direction of these associations require further investigation.

Abstract
Increasing acceptance of the idea that evolution can proceed rapidly has generated considerable interest in understanding the consequences of ongoing evolutionary change for populations, communities and ecosystems. The nascent field of 'eco-evolutionary dynamics' considers these interactions, including reciprocal feedbacks between evolution and ecology. Empirical support for eco-evolutionary dynamics has emerged from several model systems, and we here present some possibilities for diverse and strong effects in Pacific salmon (Oncorhynchus spp.). We specifically focus on the consequences that natural selection on body size can have for salmon population dynamics, community (bear-salmon) interactions and ecosystem process (fluxes of salmon biomass between habitats). For example, we find that shifts in body size because of selection can alter fluxes across habitats by up to 11% compared with ecological (that is, numerical) effects. More generally, we show that selection within a generation can have large effects on ecological dynamics and so should be included within a complete eco-evolutionary framework.

Abstract
This research examined the relation between individual differences in inhibitory control (IC; a central component of executive functioning) and theory-of-mind (ToM) performance in preschool-age children. Across two sessions, 3- and 4-year-old children (N = 107) were given multitask batteries measuring IC and ToM. Inhibitory control was strongly related to ToM, r = .66, p < .001. This relation remained significant controlling for age, gender, verbal ability, motor sequencing, family size, and performance on pretend-action and mental state control tasks. Inhibitory tasks requiring a novel response in the face of a conflicting prepotent response (Conflict scale) and those requiring the delay of a prepotent response (Delay scale) were significantly related to ToM. The Conflict scale, however, significantly predicted ToM performance over and above the Delay scale and control measures, whereas the Delay scale was not significant in a corresponding analysis. These findings suggest that IC may be a crucial enabling factor for ToM development, possibly affecting both the emergence and expression of mental state knowledge. The implications of the findings for a variety of executive accounts of ToM are discussed.

Abstract
This research examines whether children's difficulties with deception and false belief arise from a lack of inhibitory control rather than from a conceptual deficit. In 3 studies, 3-year-olds deceived frequently under conditions requiring relatively low inhibitory control (e.g., misleading pictorial cues or arrows) but failed to do so under conditions of high inhibitory control (deceptive pointing). Study 2 ruled out that the findings were due to social intimidation: Children were equally successful using an arrow to deceive under anonymous and public conditions. Study 3 indicated that, under well-controlled conditions, children did not reveal greater understanding of false belief in deceptive than nondeceptive conditions. The results of these studies suggest that children may have greater deceptive abilities than some earlier studies indicated, and that the source of their difficulty on deceptive pointing tasks lies in a failure of inhibitory control. More generally, it is argued that children's performance on false belief tasks is also likely to be affected by inhibition deficits.

Abstract
The relation between early fantasy/pretense and children's knowledge about mental life was examined in a study of 152 3- and 4-year-old boys and girls. Children were interviewed about their fantasy lives (e.g., imaginary companions, impersonation of imagined characters) and were given tasks assessing their level of pretend play and verbal intelligence. In a second session 1 week later, children were given a series of theory of mind tasks, including measures of appearance-reality, false belief, representational change, and perspective taking. The theory of mind tasks were significantly intercorrelated with the effects of verbal intelligence and age statistically controlled. Individual differences in fantasy/pretense were assessed by (1) identifying children who created imaginary characters, and (2) extracting factor scores from a combination of interview and behavioral measures. Each of these fantasy assessments was significantly related to the theory of mind performance of the 4-year-old children, independent of verbal intelligence.
