Int J Parasitol Parasites Wildl

Sarcoptic mange, caused by , is a disease that affects many species of mammals, including several wild ungulate species in the region of the European Alps, especially the Alpine chamois and the Alpine ibex, which act as parasite reservoirs. Here records of mange in alpine wild ungulates and its spread over time across the eastern parts of the European Alps are reviewed. First cases were recorded from Austria in 1824, and epizootic outbreaks have been described since then from the mountainous regions of Austria (mostly Tyrol, Carinthia, and Styria), Germany (Bavaria), Italy (Udine and Trentino) and Slovenia.

Data were collected within a governmental babesiosis compensation program.

To this end, we first derive analytically the Hessian matrix of the hypervolume indicator, a widely used performance indicator for PF approximation sets. Based on this, we propose the hypervolume Newton method (HNM) for hypervolume maximization of a given set of candidate solutions.

This goes beyond well-known diversity maintenance approaches but instead focuses on the landscape topology induced by the objective functions. More general multimodal MO problems are considered by allowing ellipsoid contours for single-objective subproblems.

The idea of using a population of search agents that collectively approximate the Pareto front resonates well with processes in natural evolution, immune systems, and swarm intelligence. Methods such as NSGA-II, SPEA2, SMS-EMOA, MOPSO, and MOEA/D became standard solvers when it comes to solving multiobjective optimization problems.
