An example of a combinatorial problem is the vehicle routing problem with time windows (VRPTW), which focuses on choosing routes for a limited number of vehicles to serve a group of customers in a restricted period. Meta-heuristics algorithms are successful techniques for VRPTW, and in this study, existing modified artificial bee colony (MABC) algo...

Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small...

Flower strips are a commonly used tool for improving agricultural landscapes for pollinators. The plant composition of the seed mixtures employed is based on logistic decisions, e.g. costs or seed availability, the literature and expert opinion, and only rarely on direct information about bee-plant interactions. We combined two datasets on bee-plan...
