A cholesterol-lowering diet score correlates with serum LDL-cholesterol: Results from the DEDiCa trial
<p>A cholesterol-lowering diet score, previously developped for epidemiological studies on seven dietary indicators, was tested to reflect serum cholesterol levels using data from DEDiCa clinical trial. Breast cancer patients with the highest adherence to the cholesterol-lowering diet reported lower LDL-cholesterol than those scarcely adherent (107 and 122 mg/dL, respectively; <em>p</em>=0.04). The difference was significant after adjustment for age, obesity, and physical activity. This provides support for the use of this score to identfy dietary patterns that reduce serum cholesterol levels.</p>

Fig. 1 in Demographic and environmental correlates of home ranges and long-distance movements of Mohave ground squirrels
Fig. 1.—Map of the Freeman Gulch study area in the west-central portion of the geographic range of the Mohave ground squirrel (MGS) in the Mojave Desert, California. The study area is approximately indicated by a minimum convex polygon drawn around all MGS radiotelemetry locations collected in 2003–2004. The Coso Range, in which MGS studies were conducted in the 1990s, is located in the northern portion of the MGS range. The top inset map shows juvenile and adult MGS locations within the Freeman Gulch study area. The cluster of locations in the extreme northeast of the inset was from a single individual that made a long-distance movement as a juvenile in 2003 and established a home range as an adult the following year. The bottom inset map shows the location of the MGS range in southern California.

Lead exposure is correlated with reduced nesting success of an urban songbird
<p>Lead exposure is a concern in urban ecosystems, with physiological and behavioral effects well documented in humans. Wildlife inhabiting urban ecosystems are also exposed to lead, yet little work has documented the sublethal effects of lead exposure in urban wildlife. We studied northern mockingbirds (<em>Mimus polyglottos</em>) in three neighborhoods of New Orleans, Louisiana, two with high soil lead and one with low soil lead, to better understand how lead exposure may influence mockingbirds' reproductive biology. We monitored nesting attempts, measured lead concentrations in the blood and feathers of nestling mockingbirds, documented egg hatching and nesting success, and assessed rates of sexual promiscuity in relation to neighborhood soil lead levels. We found that nestling mockingbirds' blood and feather lead levels reflected the lead levels of their neighborhood soil lead level and nestling blood lead levels were similar to adult mockingbirds in the same neighborhoods. Nest success, as evaluated by daily survival rates, was higher in the lower lead neighborhood. Clutch sizes varied substantially across neighborhoods, but rates of unhatched eggs did not covary with neighborhood lead levels, suggesting that other drivers are influencing variation in clutch sizes and hatching success in urban habitats. At least one-third of nestling mockingbirds were sired by an extra-pair male, and there was no relationship between extra-pair paternity rates and neighborhood lead levels. This study provides insight into how lead contamination may influence reproduction in urban-dwelling wildlife and suggests that nestling birds could serve as useful bioindicators of lead levels in urban neighborhoods.</p>

Urbanisation impacts plumage colouration in a songbird across Europe: evidence from a correlational, experimental, and meta-analytical approach
<p>Urbanisation is increasing rapidly across the globe, transforming landscapes, presenting organisms with novel challenges, shaping phenotypes, and impacting fitness. Urban individuals are claimed to have duller tones in carotenoid-based traits, the so-called ″urban dullness″ phenomenon. However, at the intra-specific level, this generalisation is surprisingly inconsistent and often based on examples from few populations or a limited geographic area. Here, combining correlational, experimental, and meta-analytical results from a common songbird, the great tit (<em>Parus</em> <em>major</em>), we investigated carotenoid-based plumage coloration in urban and forest populations across Europe. We find that, as predicted, urban individuals are paler than forest individuals, although there are large population-specific differences in the magnitude of the urban-forest contrast in colouration. Our meta-analysis indicates a non-significant effect of environmental pollution on carotenoid-based plumage for the species, suggesting that the observed differences across urban populations are not only driven by pollution. Finally, using one region as an example (Malmö, Sweden), we reveal population-specific processes behind plumage colouration differences, which are likely the result of variation in the spatial and temporal distribution of carotenoid-rich resources in anthropogenic environments. Our results provide convincing evidence for consistency on the "urban dullness" phenomenon but highlight that its magnitude depends on local urban characteristics.</p>
