Warm acclimation reduces the sensitivity of Drosophila species to heat stress at ecologically relevant scales

open access: yesJournal of Animal Ecology, EarlyView.
This study makes two key contributions to understanding thermal plasticity in ectotherms. First, we reveal non‐linear heat tolerance plasticity across species, challenging traditional linear assumptions. Second, we demonstrate that even subtle acclimation effects observed in the laboratory can significantly boost survival in natural environments ...

Recent selective sweeps in North American Drosophila melanogaster show signatures of soft sweeps [PDF]

open access: yesarXiv, 2013
Rapid adaptation has been observed in numerous organisms in response to selective pressures, such as the application of pesticides and the presence of pathogens. When rapid adaptation is driven by rare alleles from the standing genetic variation or by a high population rate of de novo adaptive mutation, positive selection should commonly generate soft ...

The changes in power requirements and muscle efficiency during elevated force production in the fruit fly Drosophila melanogaster [PDF]

open access: yes, 1997
The limits of flight performance have been estimated in tethered Drosophila melanogaster by modulating power requirements in a 'virtual reality' flight arena.

Evidence for transient deleterious thermal acclimation in field recapture rates of an invasive tropical species, Bactrocera dorsalis (Diptera: Tephritidae)

open access: yesInsect Science, EarlyView.
Abstract Knowing how environmental conditions affect performance traits in pest insects is important to improve pest management strategies. It can be informative for monitoring, but also for control programs where insects are mass‐reared, and field‐released.

Rapid evolution of ecological sexual dimorphism driven by resource competition

open access: yesEcology Letters, Volume 26, Issue 1, Page 124-131, January 2023., 2023
In an evolution experiment, I find that sexual dimorphism in diet evolves rapidly in response to resource competition, suggesting a role for ecology in driving the evolution of sexual dimorphism. Abstract Sex differences in ecologically important traits are common in animals and plants, and prompted Darwin to first propose an ecological cause of sexual

Sex Pheromone Mediates Resource Partitioning Between Drosophila melanogaster and D. suzukii

open access: yesEvolutionary Applications
The spotted‐wing drosophila, Drosophila suzukii and the cosmopolitan vinegar fly D. melanogaster feed on soft fruit and berries and widely overlap in geographic range. The presence of D. melanogaster reduces egg‐laying in D.

Diet acts on sexual behavior development in a male moth

open access: yesInsect Science, EarlyView.
Drastic changes are observed during sexual maturation characterized by the reproductive system development concomitantly to the sexual behavior ontogenesis. These modifications are under the control of internal and external factors such as food. Knowing that sexual maturation requires considerable energetic investment, diet has been shown to affect ...
