Data from: Maternal pre-pregnancy weight status modifies the influence of PUFAs and inflammatory biomarkers in breastmilk on infant growth
No full textBackground: Human breastmilk contains pro- and anti-inflammatory compounds and hormones that can influence infant growth. However, little is known about the specific interrelationships between these compounds and whether their effects on infant growth may be influenced by pre-pregnancy weight status. Objective: The purpose of this novel, prospective cohort study was to assess the interrelationships between pro-inflammatory cytokines (TNF-α, IL-6), hormones (insulin, leptin) and PUFAs (n-6, n-3) in blood and breastmilk in early postpartum between women with normal BMI (Group 1, n=18; 18.5<BMI≤24.9 kg/m2) and with overweight/obesity (Group 2, n=15; BMI≥25.0 kg/m2) before pregnancy to determine if these components correlated to infant growth measures at age 4-8 weeks. Methods: Participants were robustly phenotyped along with their infants at 4-8 weeks postpartum. TNF-α, IL-6, insulin, leptin, and n-3 and n-6 PUFAs measured in blood and breastmilk and compared between pre-pregnancy BMI groups and with infant weight, length, head circumference and % fat mass. Results: Group 1 women had higher serum leptin (p<0.01) and breastmilk leptin (p<0.001) compared to Group 2. Other inflammatory markers, hormones, and total n-6, n-3 and n-6/n-3 ratio PUFAs were similar between pre-pregnancy BMI groups. No relationships were observed between whey inflammatory markers, hormones, PUFAs and growth measures in infants born to Group 2 women. However, TNF-α was positively related and, IL-6, leptin, insulin, total n-6, n-3 and n-6/n-3 PUFAs in whey breastmilk were negatively correlated to infant growth measures in infants born to Group 1 women (p<0.01). Conclusions: Pro-inflammatory qualities of breastmilk were associated with infant growth measures regardless of maternal pre-pregnancy BMI. However, infants born to women with overweight or obesity demonstrated less responsive growth to breastmilk contents. More studies are needed to assess longitudinal effects of this impact

Data from: The role of spore size in the global pattern of co-occurrence among Selaginella species
No full textAim: Separation of regeneration niches may promote coexistence among closely related plant species, but there is little evidence that regeneration traits affect species ranges at large geographic scales. Here we address patterns of co-occurrence within the genus Selaginella, an ancient lineage of free-sporing, heterosporous, vascular plants. Specifically, we ask whether differences between species in spore size are associated with the extent of overlap in their geographic ranges, a measure of opportunity for ecological interaction. Taxon: Selaginella (Selaginellaceae: Lycopodiales) Methods: We used quantile regression to examine the relationship of spore size ratios (pairwise ratios for megaspores and microspores of co-occurring species) to the area of range overlap and to latitude for a worldwide sample of 112 Selaginella species. Phylogenetically informed tests of statistical significance were used for each percentile relationship examined in the quantile regressions. Results: Large pairwise disparities in megaspore sizes were significantly associated with large range overlap. Disparities also tended to be larger at low latitudes. Microspore size differences, in contrast, were unrelated to shared range area or latitude. Main conclusion: Megaspore size appears to affect coexistence at a broad regional scale among Selaginella species, in at least some cases. The pattern is consistent with some degree of competitive structuring of size-related aspects of dispersal and establishment of propagules among some co-occurring species. Habitat complexity, such as open microsites within otherwise closed and shaded vegetation, seems likely to promote reproductive niche separation and may account for the latitudinal structure in Selaginella spore sizes
