Complexity of the Directed Robust b‐Matching Problem and Its Variants on Different Graph Classes

Networks, EarlyView.
ABSTRACT The b$$ b $$‐matching problem is a well‐known generalization of the classical matching problem with various applications in operations research and computer science. Given an undirected graph, each vertex v$$ v $$ has a capacity bv$$ {b}_v $$, indicating the maximum number of times it can be matched, while edges can also be used multiple times.

Quantifying community keystoneness in metacommunities under disturbance

Oikos, EarlyView.
Understanding how metacommunities respond to natural and anthropogenic disturbances is a key objective in ecology. In this study, we introduce an analytical framework to identify communities whose extirpation triggers stronger (hereafter keystone communities) or weaker (hereafter idle communities) cascading effects on extinction and colonization events

Patterns and drivers of range filling of alien mammals in Europe

Oikos, EarlyView.
Biological invasions are major drivers of biodiversity change. Alien mammals are particularly concerning in Europe, where their expansion remains unabated, though the driving factors are still unclear. Well‐documented introductions and distributions in this continent provide a unique opportunity to understand how human activities influenced this ...
