Molecular evidence for an old world origin of Galapagos and Caribbean band-winged grasshoppers (Acrididae: Oedipodinae: Sphingonotus).

Patterns of colonization and diversification on islands provide valuable insights into evolutionary processes.Due to their unique geographic position and well known history, the Galapagos Islands are an important model system for evolutionary studies.Here we investigate the evolutionary history of a winged grasshopper genus to infer its origin and

Sailing: Cognition, action, communication

How do humans perceive and think about space, and how can this be represented adequately? For everyday activities such as locating objects or places, route planning, and the like, many insights have been gained over the past few decades, feeding into theories of spatial cognition and frameworks for spatial information science.In this paper, we expl

Response of oat morphologies, root exudates, and rhizosphere fungal communities to amendments in a saline-alkaline environment.

The application of organic amendments to saline-alkaline soil has been recommended as an agricultural World Band strategy to improve crop productivity and soil health.However, there has been limited research on how organic soil amendment strategies affect the health of oats and their associated rhizosphere fungal communities in saline-alkaline cond
