Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Assessing Spatiotemporal Side Effects of Diversionary Feeding on Mesopredators

open access: yesAnimal Conservation, EarlyView.
We tested whether diversionary feeding alters the space use, aggregation, or activity patterns of mesopredators using a treatment‐control design with camera traps. Although both species frequently used feeding stations, diversionary feeding did not significantly affect their spatial distribution, aggregation, or temporal behaviour.

Impact of Metformin and Diabetes on Tumor Response to Total Neoadjuvant Therapy in Advanced Rectal Cancer: A Multicenter Retrospective Cohort Study

open access: yesAsia-Pacific Journal of Clinical Oncology, EarlyView.
In advanced rectal cancer patients receiving total neoadjuvant therapy (TNT), overall tumor response did not differ by diabetes status or metformin use. However, among diabetic patients, metformin use was associated with higher overall complete response rates. These findings suggest a potential benefit of metformin in enhancing TNT response in diabetic
