Nature in cities is concentrated in urban green spaces, which are key areas for urban biodiversity and also important areas to connect people with nature. To conserve urban biodiversity within these natural refugia, habitat restoration such as weed control and revegetation is often implemented. These actions are expected to benefit biodiversity, although species known to be affected by urbaniza...

Oneof the main causes of poorweed control on sugarcane farms is the occurrence of weed germination in periods during which demands on the farm's resources are at a maximum and during which wetconditions may prevent timely herbicide application or other weed control operations. It would therefore facilitate weed control if weed germination could be predicted from meteorological data and a knowle...
