Figure 3 in The impact of predation by the myrmecophagous spider Zodarion elegans (Araneae: Zodariidae) on the activity pattern of the Mediterranean harvester ant Messor wasmanni (Hymenoptera: Formicidae)
Figure 3 Foraging activity of ants leaving the nest in correlation with absence/presence of Z. elegans individuals. Activity per day was measured as the number of leaving plus returning worker ants per min in a half-hour intervals; counts were summarized per day (0 = absence of Z. elegans, 1 = presence of Z. elegans).
Figure 5 in The impact of predation by the myrmecophagous spider Zodarion elegans (Araneae: Zodariidae) on the activity pattern of the Mediterranean harvester ant Messor wasmanni (Hymenoptera: Formicidae)
Figure 5. Tasks performed by marked foragers inside the nest when nest entrances were closed due to predation pressure. The number of workers per activity was summarized during the duration of three perturbation experiments. Per experiment 30 workers – 10 Minor-workers, 10 Medium-workers and 10 Major-workers – were marked.

Figure 1. Frequency of Z. elegans individuals found within a distance of max. 0.5 m to active/inactive ant colonies in a) spring 2009, b) summer 2009 and c) autumn 2009 (1 = active colonies, 0 = inactive colonies).
Figure 2 in The impact of predation by the myrmecophagous spider Zodarion elegans (Araneae: Zodariidae) on the activity pattern of the Mediterranean harvester ant Messor wasmanni (Hymenoptera: Formicidae)
Figure 2 Flow diagram of nest entrance closure in response to prey capture by the spider Z. elegans. In total, four experiments were performed with an overall duration of 100 days (Trial 1: n = 20, Trial 2: n = 30, Trial 3: n = 30, Trial 4: n = 20, n(total) = 100). The capture of M. wasmanni workers by Z. elegans is necessary to prompt ants to end aboveground activity and close nest entrances. By contrast, the presence of spiders in the formicarium alone was not sufficient to prompt ants to close nest entrances after aboveground foraging activity ceased.

Data from: Impacts of weathered microplastic ingestion on gastrointestinal microbial communities and health endpoints in fathead minnows (Pimephales promelas)
<p>Microplastics are a ubiquitous presence in the world's aquatic environments and their threat to aquatic biota is poorly understood, especially in freshwater ecosystems. In the environment, microbial biofilms can form on the surface of microplastics, and these plastics have the potential to adsorb harmful toxins. Because lab-based studies on microplastics are often conducted with clean polymers, in ecologically unrealistic conditions and concentrations, the impact of these weathered microplastics on aquatic organisms in ecologically realistic conditions is still unclear. To help address the need for ecologically relevant microplastic exposure data, we incubated 500 μm polyethylene microplastic beads in Muskegon Lake, Michigan, USA and used them to conduct a 28-day ingestion study with male and female fathead minnows (<em>Pimephales promelas</em>). We examined the effects of microplastic ingestion on the fish gut microbial community along with hepatic gene expression and health parameters. We found that microplastic ingestion had statistically significant impacts on growth in male fathead minnows. Microplastic treatment did not significantly alter the beta diversity of the gut microbial community for either males or females, but there were clear differences between sexes and over time, indicating that these factors may outweigh the impacts of microplastic ingestion on beta diversity in the gut. The expression of immune response genes was not altered in males. It did, however, cause some changes to alpha diversity metrics in both sexes and there were several differentially abundant taxa among treatments. These data suggest that microplastic ingestion has health effects, but these effects may be sex specific across certain species and they are likely not being solely driven by changes in gut microbial communities.</p>
