Data from: Parasite-offspring competition for female resources can explain male-biased parasitism in plants

Kirsty J. Yule & Kevin C. Burns
Male-biased susceptibility to parasites is common in dioecous plants. However, why males have higher parasite loads than females is unclear. Unlike males, females have to subsidize post-fertilization costs of reproduction (e.g. seed and fruit development). As a result, females may have smaller pools of resources potentially available to parasites, thus leading to lower parasite loads. We tested this prediction in New Zealand’s largest native moth (Aenetus virescens: Lepidoptera), whose larvae parasitize Aristotelia serrata (Elaeocarpaceae), an...

Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in Studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on...

A coralline alga gains tolerance to ocean acidification after multiple generations of exposure: data

Christopher Cornwall
Crustose coralline algae (CCA) play a crucial role in the building of reefs in the photic zones of nearshore ecosystems globally and are highly susceptible to ocean acidification. Yet the extent to which CCA can gain tolerance to ocean acidification over multiple generations of exposure is unknown. We show that while calcification of juvenile CCA is initially highly sensitive to ocean acidification, after 6 generations of exposure the effects of ocean acidification disappears. A reciprocal...

Data from: Fitness and microbial networks of the common wasp, Vespula vulgaris (Hymenoptera: Vespidae), in its native and introduced range

Monica A. M. Gruber, Oliver Quinn, James W. Baty, Jana Dobelmann, John Haywood, T. Wenseleers & Philip J. Lester
1. Variation in microbial communities between populations is increasingly hypothesized to affect animal fitness and performance, including for invasive species. Pathogenic species may be lost during the introduction process, enhancing invader fitness and abundance. 2. We assessed fitness, immune gene expression, and microbial network complexity of invasive common wasps, Vespula vulgaris. Microbial networks were assayed using 16S and 18S sequencing and gene expression arrays in the native (Belgium) and introduced range (New Zealand). We examined...

Data from: Ocean acidification during pre-fertilization chemical communication affects sperm success

Rowan Lymbery, Jason Kennington, Christopher Cornwall & Jonathan Evans
Ocean acidification (OA) poses a major threat to marine organisms, particularly during reproduction when externally shed gametes are vulnerable to changes in seawater pH. Accordingly, several studies on OA have focused on how changes in seawater pH influence sperm behaviour and/or rates of in vitro fertilization. By contrast, few studies have examined how pH influences pre-fertilization gamete interactions, which are crucial during natural spawning events in most externally fertilizing taxa. One mechanism of gamete interaction...
