Drivers of thermal tolerance breadth of plants across contrasting biomes

V. F. Briceno, P. A. Arnold, A. M. Cook, S. K. Courtney Jones, R. V. Gallagher, K. French, L. A. Bravo, A. B. Nicotra, A. Leigh

This study examines how climate variability affects thermal tolerance in plants across three biomes, finding that thermal variability increases cold tolerance but not heat tolerance.

Testing the evolutionary potential of an alpine plant: Phenotypic plasticity in response to growth temperature far outweighs parental environmental effects and other genetic causes of variation

P. A. Arnold, S. Wang, R. F. Notarnicola, A. B. Nicotra, L. E. B. Kruuk

This study quantifies phenotypic plasticity and genetic variation in Wahlenbergia ceracea, finding strong plastic responses to growth temperature over parental effects and genetic variation.

Molecular signatures of heat tolerance in an Australian alpine plant during moderate warming

R. F. Notarnicola, J. Hamilton, P. A. Arnold, A. Jones, S. Loke, Z.-P. Feng, A. Schmidt-Lebuhn, B. Schwessinger, A. B. Nicotra, D. R. Ganguly

This study examines the transcriptomic response of Wahlenbergia ceracea to sustained moderate warming, identifying gene regulation patterns linked to heat tolerance.

A high-throughput method for measuring critical thermal limits of leaves by chlorophyll imaging fluorescence

P. A. Arnold, V. F. Briceno, K. M. Gowland, A. A. Catling, L. A. Bravo, A. B. Nicotra

The paper develops a high-throughput method to measure critical thermal limits of leaves using chlorophyll fluorescence, finding that heating/cooling rates and leaf surface conditions affect these thresholds.

Drosophila melanogaster infected with Wolbachia strain wMelCS prefer cooler temperatures

P. A. Arnold, S. C. Levin, A. L. Stevanovic, K. N. Johnson

The paper finds that Wolbachia-infected Drosophila melanogaster prefer cooler temperatures than uninfected flies, suggesting a potential thermoregulatory effect of the bacteria.
