Journal of Phycology, EarlyView.Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Ant colony optimization: A bibliometric review
Physics of Life ReviewsThis paper is a follow-up of one of the most-cited articles published in the first 20 years of the existence of Physics of Life Reviews. The specific topic is "ant colony optimization", which is a metaheuristic for solving challenging optimization problems.

Ecological change may be a common initiator of evolutionary pollinator shifts
New Phytologist, EarlyView.Summary Although evolutionary pollinator shifts are accepted as major sources of floral and species diversity in angiosperms, the mechanisms triggering pollinator shifts remain largely unexplored. In 1970, Stebbins proposed that ecological change may be a common initiator of evolutionary pollinator shifts, but empirical tests of Stebbins' hypothesis ...

Restoration Ecology, EarlyView.Abstract Introduction Restoration in drylands is challenging because of harsh climates, requiring creative methods and organisms like biocrusts for restoration of degraded lands. Biocrusts are thin, coherent soil surface layers prevalent in drylands, engineered, and inhabited by communities of organisms including mosses, lichens, and cyanobacteria ...

Seeing Through an Ant's Eyes: Do Entomopathogenic Fungi Extend Their Cognition to Their Hosts?
Topics in Cognitive Science, EarlyView.Abstract Post‐cognitivist approaches recognize cognition as a phenomenon that involves not just brains but all the sensorimotor apparatus of organisms. This means that brains are not always required for the emergence of cognition and that every organism can, in principle, be cognitive, unlocking a theoretical framework to explain the complex adaptive ...

Incorporating waiting time in competitive location models: Formulations and heuristics [PDF]
In this paper we propose a metaheuristic to solve a new version of the Maximum Capture Problem. In the original MCP, market capture is obtained by lower traveling distances or lower traveling time, in this new version not only the traveling time but also
