“…One of the largest pillars of invasion ecology is understanding what happens to parasite faunas when host species become established in a new region (Keogh et al 2017;Kołodziej-Sobocińska et al 2018a;Laurimaa et al 2016;Poulin 2017;Stricker et al 2016). Commonly debated questions include: Which parasites are prevalent in native ranges but absent in new territories, and vice versa?…”

“…INNS that escape their native range may benefit not only from reduced parasite pressure at the beginning of the invasion, but also from relaxed selection for costly immune response, which promotes reallocation of available resources toward growth, reproduction, and survival. As a result, invasive hosts may be less infected but-on the other hand-more susceptible to infection due to the weakening of defense mechanisms (Keogh et al 2017).…”

There are many different factors involved in parasitism. The general concept of Bfilters^proposed by Combes includes Bencounter filters^(behavior, biodiversity) and Bcompatibility filters^(resources, defense) to explain mechanisms responsible for the formation of host-parasite coexistence. However, researches explaining the reasons for the spread and dynamics of parasites in populations of wild terrestrial mammals in Europe and the specific factors affecting prevalence and intensity of parasitosis are limited. Many factors, ecological, biological, and anthropogenic, form a complex network of interdependencies that shape this pattern. Here, I summarize the current state of knowledge on the factors affecting parasitic diseases in wild mammals inhabiting the European continent. It indicates the need to further development, not only for academic reasons, but also for the benefit of use in management of wild mammal species and disease control in nature.

“…Even more important are the indirect effects by the reduced need to invest in parasite defense, allowing organisms to reallocate those resources to traits like growth or reproduction (Goedknegt et al 2016). Reduced investment in parasite defense, however, results in higher susceptibility to parasite infections, which may in turn negatively impact establishment success (Keogh et al 2016). Introduced non-native parasites, on the other hand, can reach extreme invasion success when they are able to infect native species which are closely related to their original host, but have only weak defensive traits due to the lack of coevolution (examples in Ruiz et al 1999;Feis et al 2016).…”

YOUMARES 8 – Oceans Across Boundaries: Learning From Each Other

View full text Add to dashboard Cite

From the depths of the oceans to the shallow estuaries and wetlands of our coasts, organisms of the marine environment are teeming with unique adaptations to cope with a multitude of varying environmental conditions. With millions of years and a vast volume of water to call their home, they have become quite adept at developing specialized and unique techniques for survival and-given increasing human mediated transport-biological invasions. A growing world human population and a global economy drives the transportation of goods across the oceans and with them invasive species via ballast water and attached to ship hulls. In any given 24-hour period, there are about 10,000 species being transported across different biogeographic regions. If any of them manage to take hold and establish a range in an exotic habitat, the implications for local ecosystems can be costly. This review on marine invasions highlights trends among successful non-indigenous species (NIS), from vectors of transport to ecological and physiological plasticity. Apart from summarizing patterns of successful invasions, it discusses the implications of how successfully established NIS impact the local environment, economy and human health. Finally, it looks to the future and discusses what questions need to be addressed and what models can tell us about what the outlook on future marine invasions is.

“…While R. harrisii has been introduced to many global regions, in all of these cases it appears that L. panopaei has not yet followed it (Fofonoff, Ruiz, Steves, Simkanin, & Carlton, 2019;Fowler, Forsström, von Numers, & Vesakosk, 2013 (Phillips et al, 2010;Keogh, Miura, Nishimura, & Byers, 2017). Thus, the existence of multiple host introductions from multiple sources, with a variety of histories of parasitism, provides a uniquely promising system in which to explore the potential influence of host-parasite coevolution on biological introductions.…”

Parasitism can represent a potent agent of selection, and introduced parasites have the potential to substantially alter their new hosts' ecology and evolution. While significant impacts have been reported for parasites that switch to new host species, the effects of macroparasite introduction into naïve populations of host species with which they have evolved remain poorly understood. Here, we investigate how the estuarine white‐fingered mud crab (Rhithropanopeus harrisii) has adapted to parasitism by an introduced rhizocephalan parasite (Loxothylacus panopaei) that castrates its host. While the host crab is native to much of the East and Gulf Coasts of North America, its parasite is native only to the southern end of this range. Fifty years ago, the parasite invaded the mid‐Atlantic, gradually expanding through previously naïve host populations. Thus, different populations of the same host species have experienced different degrees of historical interaction (and thus potential evolutionary response time) with the parasite: long term, short term, and naïve. In nine estuaries across this range, we examined whether and how parasite prevalence and host susceptibility to parasitism differs depending on the length of the host's history with the parasite. In field surveys, we found that the parasite was significantly more prevalent in its introduced range (i.e., short‐term interaction) than in its native range (long‐term interaction), a result that was also supported by a meta‐analysis of prevalence data covering the 50 years since its introduction. In controlled laboratory experiments, host susceptibility to parasitism was significantly higher in naïve hosts than in hosts from the parasite's native range, suggesting that host resistance to parasitism is under selection. These results suggest that differences in host–parasite historical interaction can alter the consequences of parasite introductions in host populations. As anthropogenically driven range shifts continue, disruptions of host–parasite evolutionary relationships may become an increasingly important driver of ecological and evolutionary change.
