published in Journal of Thermal Biology 135 (2026) 104352; https://doi.org/10.1016/j.jtherbio.2025.104352 

The attached four files, as listed below, contain the raw data as collected from the experiments described in Canal Domenech & Fricke 2026.

1) Offspring number
2) Recover time
3) Accessory gland size
4) Sperm presence


Detailed description of the data contained in the individual files.

1) Offspring number	
	
Male_ID		individual male identifier
Temperature	temperature treatment males experienced during development given as °C
Day		test day (= male age) post-eclosion
Offspring_num	number of offspring produced within 24 hours 
Species		Drosophila species measured: D. melanogaster, D. mauritania, D. simulans and D. obscura
	
2) Recovery time	
	
Male_ID		individual male identifier
Develop_temp	temperature treatment males experienced during development given as °C
Species		Drosophila species tested: D. melanogaster, D. mauritania, D. simulans and D. obscura
Recovery_t	recovery time in hours
New_temp	temperature coded as increases of 1°C temperature steps from the control temperature 
Status		score whether a male recovered (1-) or not (0-)
	
3) Accessory gland size 	
	
Male_ID		individual male identitfier
Temperature	temperature treatment males experienced during development given as °C
Day		test day (= male age) post eclosion
Area1		area of the first accessory gland in µm
Area2		area of the second accessory gland in µm
Wing_L1		length of the first wing in µm
Wing_L2		length of the second wing in µm
Species		Drosophila species measured: D. melanogaster, D. mauritania, D. simulans and D. obscura
	
4) Sperm presence 
	
Male_ID		individual male identifier
Temperature	temperature treatment males experienced during development given as °C
Day		test day (= male age) post eclosion
T1		sperm presence (1- present, 0- absent) in the first testis
T2		sperm presence (1- present, 0- absent) in the second testis
Species		Drosophila species scored: D. melanogaster, D. mauritania, D. simulans and D. obscura
