      Meta-Analysis Addressing Knowledge and Data Gaps Toward an Improved Synthesis of 
      Research Outputs.

AB  - Maternal transfer of persistent organic pollutants (POPs) confronts developing 
      embryos with a pollution legacy and poses conservation concerns due to its 
      potential impacts unto subsequent generations. We conducted a systematic review 
      focusing on: 1) processes of POP maternal transfer, 2) challenges and 
      opportunities to synthesizing current knowledge on POP concentrations in eggs, 
      and 3) a meta-analysis of patterns in current egg pollution data. Results suggest 
      selective maternal transfer of individual compounds. These relate to biological 
      factors such as the foraging and remigration behavior, and to the selective 
      mobilization of POPs during vitellogenesis, such as increased diffusion 
      limitation for lipophilic POPs and slower release and higher reabsorption of 
      apolar POPs. A key gap relates to knowledge of further selective toxicokinetics 
      during embryonic development, as research to date has mainly focused on initial 
      uptake into eggs. Challenges in the synthesis of current data on egg 
      contamination profiles relate to methodological differences, varying analytical 
      approaches, restricted data access, and reporting transparency among studies. To 
      increase opportunities in the use of current data, we propose best practice 
      guidelines, and synthesize a database on POP concentrations within sea turtle 
      eggs. The meta-analysis revealed a geographical and taxonomic bias on the West 
      Atlantic Ocean, including the Gulf of Mexico and Caribbean Sea, with most studies 
      conducted on green turtles. Concentrations of POPs show temporal patterns related 
      to trends in usage, production, release, and persistence in the environment, 
      often with regional patterns. The trophic level has the potential to influence 
      POP patterns with higher concentrations in loggerheads compared to other species, 
      but this is confounded by temporal and geographic trends. We argue for more 
      mechanistically process-focused and methodologically comparable research. Environ
