Background: Phthalates are a group of endocrine disrupting chemicals that are heavily used throughout industry in flexible plastic and personal-care products. As a result, detectable levels of their metabolites are readily found in humans. Some studies have shown associations of phthalates with diabetes, but associations with gestational diabetes mellitus (GDM) are less clear.

- Monodominant forests in tropical areas, like the one in Northeastern Costa Rica dominated by Pentaclethra macroloba, can arise from ecological and evolutionary factors, notably high seed and seedling mortality leading to vegetative reproduction.
- The study examined juvenile P. macroloba across different soil types and elevations, revealing that clonal reproduction is exclusive to swamp areas, while genetic diversity was consistently low in both swamp and non-swamp plots.
- Significant genetic structure exists among all plots, with higher structure in swamp areas and specific spatial patterns indicating limited dispersal within non-swamp plots.
