Physiological effects of developmental exposure to flame retardant mixture Firemaster 550 or it's components
<p><span>Firemaster 550 (FM550) is a flame retardant (FR) mixture which has become one of the most commonly used FRs in household items such as foam-based furniture and baby products. Because this mixture readily leaches from products, contamination of the environment and human tissues is widespread. Prior work by us and others </span>has reported sex-specific behavioral deficits in rodents and zebrafish following early life exposure. In an effort to understand the mechanisms by which these behavioral effects occur, here we explored the effects of its constituents on behavioral outcomes previously shown to be altered by developmental FM550 exposure. <span>The FM550 commercial mixture is composed of </span>two brominated compounds (BFR) and two organophosphate compounds (OPFRs) at almost equivalent proportions. Both the BFR and the OPFR components are differentially metabolized and structurally distinct, but similar to known neurotoxicants. Here we examined adult Wistar rat offspring socioemotional behaviors following perinatal exposure (oral, to the Dam) to vehicle, 2000 µg/day FM550, 1000 µg/day BFR or 1000 µg/day OPFR from gestation day 0 to weaning. Beginning on postnatal day 65 offspring from all groups were subjected to a series of behavioral tasks including open field, elevated plus maze, marble burying, social interaction tests, and running wheel. Effects were exposure-, sex- and task-specific, with BFR exposure resulting in the most consistent behavioral deficits. Overall, exposed females showed more deficits compared to males across all dose groups and tasks. These findings help elucidate how different classes of flame retardants, independently and as a mixture, contribute to sex-specific behavioral effects of exposure.</p>

Interactive effects of tree species mixture and climate on foliar and woody trait variation in a widely distributed deciduous tree
<p><span>Despite increasing reports of severe drought and heat impacts on forest ecosystems, c</span>ommunity-level processes, which could potentially modulate tree responses to climatic stress, are rarely accounted for. While numerous studies<span> indicate a positive effect of species diversity on a wide range of ecosystem functions and services, little is known about how species interactions influence tree responses to climatic variability. We quantified the intraspecific variation in 16 leaf and wood physiological, morphological, and anatomical traits in mature beech trees (<i>Fagus sylvatica</i> L.) at six sites located along a climatic gradient in the French Alps. At each site, we studied pure beech and mixed stands with silver fir (<i>Abies alba </i>Mill.) or downy oak (<i>Quercus pubescens </i>Willd.). We tested how functional traits differed between the two species mixtures (pure <i>vs</i>. mixed stands) within each site and along the climatic gradient. We found significant changes in many traits along the climatic gradient </span>as conditions progressively got drier and warmer<span>. Independent of the mixture, reduced leaf-level CO<sub>2</sub> assimilation, stomatal size, and thicker leaf cuticles, consistent with a more conservative resource use strategy, were found. At the drier sites, higher foliar stable carbon isotopic composition (</span><span>d</span><sup><span>13</span></sup><span>C), thicker mesophyll tissues, and lower specific leaf area (SLA) in pure stands suggests that beech had more acquisitive traits there compared to mixed stands. At the wetter sites, trees in beech-silver fir mixtures had higher chlorophyll concentration, lower </span><span>d</span><sup><span>13</span></sup><span>C, larger xylem vessels, and higher SLA, suggesting a more acquisitive resource use strategy in mixed stands than in pure stands. </span>Our work revealed that species interactions are significant modulators of functional traits, and that they can be just as important drivers of intraspecific trait variation as climatic conditions. <span>We show that downy oak mixtures lead to an adaptive drought response by common beech in dry environments. In contrast, in milder climates, interactions with silver fir seem to increase beech' resource acquisition and productivity. These findings highlight a strong context-dependency and imply that incorporating local interspecific interactions in research on climate impacts could improve our understanding and predictions of forest dynamics.</span></p>
