“…A recent study (Duxbury & Chapman, 2020), which aimed to test between the silverspoon and environmental matching hypotheses, manipulated developmental and adult nutrition, and found that female reproductive senescence was affected by an interaction between developmental and adult diets. However, another study that manipulated both adult and developmental temperatures in Drosophila found results similar to ours (Min et al, 2020). Specifically, they found that adult temperature had a greater effect on age-dependent survival than developmental temperature, and that hot adult temperatures were deleterious for adult survival senescence.…”

“…Additional complexity to the tangled interactions between early and late life conditions arises from the fact that responses to environmental stimuli can be trait-and sex-dependent (e.g. Duxbury & Chapman, 2020;Helle et al, 2012;Krause et al, 2017;Min et al, 2020;Pigeon et al, 2019;Santos et al, 2021;Scharf, Braf et al, 2015;Stillwell & Fox, 2005). For example, in cichlids reproductive rate is determined only by nutrition during development, while adult growth rate is determined only by nutrition in the adult stage, and clutch size is determined by both developmental and adult life nutrition (Taborsky, 2006).…”

Early and late life environments can interact in complex ways to influence the fitness of individuals. Most studies investigating effects of the environment on fitness focus on environments experienced and traits expressed at a single point in an organism's life. However, environments vary with time, thus the environments organisms experience at different ages may interact to affect how traits change throughout life. Here, we test whether thermal stress experienced during development leads individuals to cope better with thermal stress as adults. We manipulated temperature during both development and adulthood and measured a range of life-history traits, including senescence, in male and female seed beetles, Callosobruchus maculatus. We found that favourable developmental conditions increased reproductive performance of females (i.e. silver-spoon effects). In contrast, non-reproductive traits such as lifespan and survival senescence were only affected by adult environments- high adult temperatures decreased longevity and survival. Additionally, developmental and adult environments interacted to affect age-dependent changes in male weight. Overall, our results show that effects of early and late environments can be both sex- and trait- specific, and that a full understanding of how environments interact to affect fitness and ageing requires the integrated study of conditions experienced during different stages of ontogeny.

“…One popular empirical approach for implementing the mismatched environment 8 test for PARs relies on estimating a regression with interaction effects between developmental and adult environmental quality 9 [e.g. 14, 27, 26, 32, 11, 63, 33, 52, 42], i.e., where u is a regression error term. We will hereafter refer to this equation as the interaction regression.…”

Early life conditions can have profound effects on individual health, longevity, and biological fitness. Two classes of hypotheses are used to explain the evolutionary origins of these effects: developmental constraints (DC) hypotheses, which focus on the deleterious effects of low-quality early-life environments, and predictive adaptive response (PAR) models, which focus on organisms predictions about their adult environment, phenotypic adaptations based on that prediction, and the deleterious consequences of incorrect predictions. Despite their popularity, these ideas remain poorly defined. To remedy this, we provide mathematical definitions for DC, PARs, and related concepts, and develop statistical tests derived from these definitions. We use simulations to demonstrate that PARs are more readily detected by tests based on quadratic regressions than by tests based on more commonly used interaction regression models. Specifically, quadratic regression-based tests on simulated data yield 90.7% sensitivity and 71.5% specificity in detecting PARs, while interaction-based tests yield sensitivity and specificity roughly equal to chance. We demonstrate that the poor performance of interaction models stems from two problems: first, they are mathematically incapable of detecting a central prediction of PAR, and second, they conceptually conflate PARs with DC. Our results emphasize the value of formal statistical modeling to reveal the theoretical underpinnings of verbal and visual models, and their importance for helping resolve conflicting and ambiguous results in this field of research. We conclude by providing recommendations for how researchers can make use of explicit definitions and properly-aligned visualizations and statistical tests to make progress in this important research area.

Günümüzde nanopartiküllerin üstün fizikokimyasal özelliklerinin belirlenmesinden sonra nanopartiküller ve nanoteknolojiye olan ilgi de hızlı bir şekilde artmış ve kullanım alanları da yaygınlaşmıştır. Üç fiziksel boyutundan en az biri 1-100 nm aralığında olan ve belirli nano-ölçekli özellikler gösterebilen maddeler olarak tanımlanan nanopartiküller, tıp, elektronik, kozmetik, çevresel temizlik gibi birçok farklı alanda yaygın kullanım alanına sahiptir. Bu yaygın kullanımdan dolayı insanların da nanopartiküllere olan maruziyeti gün geçtikçe artmaktadır. Ayrıca nanopartiküllerin çevreye yayılması doğada ki birçok canlı için risk oluşturmaktadır. Bu sebeple de nanopartiküllerin yol açabileceği olumlu/olumsuz biyolojik etkilerin anlaşılabilmesi için yapılan çalışmalar da hız kazanmıştır. Bu bağlamda yapılan çalışmada MgO nanopartiküllerinin farklı konsantrasyonlarının (2, 5 ve 10 mM) Drosophila melanogaster üzerindeki davranışsal toksisiteye etkisinin araştırılması amaçlanmıştır. Davranışsal toksisitenin belirlenmesinde larval ağırlık ve hareketi, ergin birey ağırlığı, pupa oluşturma başarısı, pupa pozisyonu, pupadan çıkış başarısı, negatif jeotaksis ve ömür uzunluğu deneyleri gerçekleştirilerek değerlendirilmiştir. Çalışma sonucunda MgO NP'lerinin genel olarak Drosophila melanogaster'da negatif bir etkiye neden olduğu tespit edilmiştir. Larval hareketin incelendiği deney kapsamında çalışma kapsamında en yüksek doz olarak belirlenen 10 mM'lık derişimin istatistiksel olarak anlamlı bir şekilde azalmaya neden olduğu tespit edilmiştir.
