Abiotic environmental variation drives virulence evolution in a fish host–parasite geographic mosaic

Parasite virulence varies greatly. Theory predicts that this arises from parasites optimising a trade‐off between the mortality they inflict on current hosts, and their transmission to future hosts. The effect of the environment on this co‐evolution is rarely considered. Geographic mosaics are fertile systems for studying co‐evolution, but again, the diversity of outcomes is often assumed to result from co‐evolutionary dynamism, rather than being moulded by the environment. Here, we quantify variation in virulence among lakes in a geographic mosaic of co‐evolution between a trematode ectoparasite (Gyrodactylus arcuatus) and its three‐spined stickleback (Gasterosteus aculeatus) host. Virulence varies greatly in this system, and parasites are generally locally adapted to their hosts. Parasites are also locally adapted to the water in their own lake, and virulence is strongly related to lake pH, the dominant axis of abiotic environmental variation in this system. These results suggest that the evolution of virulence can be substantially affected by the abiotic environment, which has important implications for understanding co‐evolution. There are also implications for the evolutionary management of disease, e.g. ectoparasites in aquaculture, the impacts of which might be expected to reduce given ongoing acidification of aquatic ecosystems.

“…Heavy metals are well-established to be detrimental to human health and the environment (Turkdogan et al 2003;Kawata et al 2007;Gheorghiu et al 2007). Emissions arising from transport system are one of the most important sources of heavy metal pollution.…”

Heavy metal concentration in soil was investigated at three sites with different topography (cut slope, flat and embankment) within the vicinity of Chengdu-Kunming railway in Sichuan, China. Surface soil was sampled at certain distances from the track at each site and was analyzed for Cu, Mn, Pb, Zn, Cd by atomic absorption spectrometry. Cu, Cd and Zn concentrations in some soil exceeded the thresholds for non-polluted soil following the soil quality standard set by the State Environmental Protection Agency of China. Compared to local background values, the highest enrichment factor values of Cu, Mn, Zn and Cd were 2.7, 3.4, 3.7 and 7.7, respectively, indicating a moderate or significant enrichment of these metals in soil closest to the railway. Pb showed little accumulation with the EF values generally nearer 1 at the chosen sites. Topography profile was found to influence metal levels and distribution in soil alongside railway. At the cut slope site, Mn, Zn, Cd showed the highest concentrations and the smallest dispersion distance of 2 m, while Cu showed further dispersion distance of 25 m due to a main Cu emission source, the head-over traction cable, being located higher than any other metal emission source (wheels and tracks). Heavy metal concentrations decreased conversely as compared to distance from the track, peak values occurring at locations closest to the tracks, whilst embankment site soil Cd concentrations peaked at distances of 25 m. Significant correlation was found amongst Mn, Cu, Zn and Cd, which indicates that these metals have the same anthropogenic origin there. Organic matter content had no significant correlation to the elements Mn, Cu and Zn, which implies relatively high mobility to those metals.

The results of chromium mass balance, presented in Table 2, show that the greatest amount of Cr(III) was retained inside the column when scrap iron powder was used as reducing reagent.…”

“…Unlike most organic pollutants, metals environmental contaminants are particularly problematic because they are non-biodegradable and can accumulate in living tissues, thus becoming concentrated throughout the food chain [1]. Although at low doses some heavy metals are essential micronutrients for plants and animals, being responsible for biochemical, immunological and physiological activities [2][3][4][5][6], in higher doses they can detrimentally affect the health of most living organisms [7][8][9][10][11][12].…”
