Effects of a high cholesterol diet on Drosophila chill tolerance are highly context-dependent

M. C. Allen, M. W. Ritchie, M. I. El-Saadi, H. A. MacMillan

This study examines how a high cholesterol diet affects chill tolerance in Drosophila, finding context-dependent effects on acute and chronic chilling injury mechanisms.

The digestive system of a cricket pulverizes polyethylene microplastics

M. W. Ritchie, J. Provencher, J. E. Allison, M. J. Muzzatti, H. A. MacMillan

This study shows that crickets can fragment ingested microplastics into smaller pieces during digestion, potentially acting as agents of plastic transformation in the environment.

Characterizing microplastic ingestion, transformation, and excretion in insects using fluorescent plastics

M. W. Ritchie, A. Cheslock, M. P. T. Bourdages, B. M. Hamilton, J. F. Provencher, J. E. Allison, H. A. MacMillan

The paper develops a method to isolate and characterize fluorescent microplastics in insects using a combined workflow of tissue dissection, digestion, filtering, and imaging.

Ingestion of microplastic fibres, but not microplastic beads, impacts growth rates in the tropical house cricket Gryllodes sigillatus

S. Fudlosid, M. W. Ritchie, M. J. Muzzatti, J. E. Allison, J. Provencher, H. A. MacMillan

This study finds that high concentrations of polyethylene terephthalate microfibers reduce female Gryllodes sigillatus body size and weight, while polyethylene beads have no significant effect.

A simple and dynamic thermal gradient device for measuring thermal performance in small ectotherms

M. W. Ritchie, J. W. Dawson, H. A. MacMillan

The paper introduces a thermal gradient device for measuring thermal performance in small ectotherms, demonstrating its use in generating survival curves and analyzing thermal effects on growth rates.

Multidecadal decline and recovery of aspen experiencing contrasting fire regimes: long-unburned, infrequent and frequent mixed-severity wildfire

C. Brewen, J.-P. Berrill, M. W. Ritchie, K. Boston, C. M. Dagley, B. Jones, M. Coppoletta, C. L. Burnett

This study examines how aspen stands respond to different fire regimes over time, finding that fire promotes aspen recovery by reducing conifer competition, while fire exclusion leads to decline.

Warm periods in repeated cold stresses protect Drosophila against ionoregulatory collapse, chilling injury, and reproductive deficits

M. I. El-Saadi, M. W. Ritchie, H. E. Davis, H. A. MacMillan

This study shows that warm periods during repeated cold stresses improve survival, recovery, and reproduction in Drosophila melanogaster by mitigating ionoregulatory collapse.
