The gap

Evidence profile

Sourced from the stated research gap and abstract and limitations section and future-work section of the source papers, classified as general, drawn from work published between 2025 and 2026, spanning 3 journals. Those papers have been cited 34 times in total.

Supporting evidence — 5 representative gaps

• Soil Physicochemical Parameters and Bibliographically Inferred Microbial Diversity as Drivers of Early-Stage Biodegradation of Colocasia esculenta and Manihot esculenta Starch Bioplastics in Three High-Andean Soils of Ecuador (2026) · Polymers · doi

  Field-relevant degradation data for tropical high-altitude soils remain scarce. The gap is framed by the lack of understanding of how the physicochemical properties and microbial context of high-Andean soils affect the biodegradability of starch-based bioplastic films.
