Resumen de Ups and downs of wildlife population regulation by macroparasites
Whilst many empirical studies have quantified the negative impact of parasites on host vital rates (survival, fecundity, etc.), few have come close to demonstrating that macroparasites are capable of regulating wildlife host populations. Arguably the only convincing demonstration of the regulatory effect of macroparasites on a wildlife host comes from the red grouse–Trichostrongylus tenuis system in northern England, where the impact of macroparasites was demonstrated at both the individual and population levels. However, even this study is not without its critics. Now, a new study adds additional weight to the idea that macroparasites can be important regulating agents [ 1. ].
