Datasets for the active, standard, and digestive metabolic rate. Additionally, the behavior and composition data sets for wolf spiders were included.

Mating bears costs, but how these costs affect the senescence of reproductive traits in males received relatively little attention. Males of many species show reduced expression of pre- and post-copulatory reproductive traits during ageing. Senescence of post-copulatory reproductive traits is often linked to a reduction in sperm quantity and quality, but can also be a consequence of changes in seminal fluid proteins that are transferred alongside sperm during mating. Here we investigated how mating history affects male reproductive ageing, especially at the post-copulatory level, using Drosophila melanogaster, a species in which links between seminal fluid proteins and male reproductive traits are well established. Besides a male cohort kept virgin until the start of the experiment we also included a cohort of males kept together with females allowing for ample mating opportunities. With these males we conducted a series of behavioral experiments covering several aspects of male reproductive success with males ranging in age from 4 days to 6 weeks after eclosion. Additionally, we investigated the storage capacity of male accessory glands (AG), the production site of the majority of seminal fluid proteins. We found that reproductive traits declined in expression with increasing male age and, most importantly, males with prior matings showed a reduced performance in pre-copulatory traits. However, our data suggest a constant short-term cost of mating rather than an accelerated senescence of pre-copulatory traits. In contrast, senescence of post-copulatory reproductive traits differed between mated and virgin males, hinting at mating costs in males altering the ageing process. We could not find any differences in the capacity of the AG to store seminal fluid proteins, however, our data suggest that old males transfer fewer seminal fluid proteins in a single mating.

Immunoassay dataset for wing-dimorphic <i>Gryllus firmus</i> crickets. Includes encapsulation, phenoloxidase activity, and lysozyme activity.

R script for ant survival and original data on ant mortality

This data contains four tabs. The first tab is a legend that describes the three data tabs, which contain the data analyzed in the manuscript. The weight data tab contains data on cricket weight throughout the 32 days of the experiment as well as the temperature treatments to which the sampled crickets belonged. The incorporation data tab contains all the carbon isotope values, the corresponding day of the experiment that the crickets were sampled, the temperature treatment to which the crickets belonged, and a unique ID for each cricket. The trophic discrimination tab contains the trophic discrimination values and the corresponding temperature treatments.
