An analysis has been carried for rainfall data in the Czech Republic over the period 1961 to 2011 (10). The contribution of heavy, short-term precipitation to the precipitation total significantly increased at about half of 17 weather stations spread over the country. However, whether these changes are due to climate change is yet unclear.
Best Answer: Locusts and grasshoppers are identical in appearance - how they differ is in their behaviour. Locusts can exist in two different behavioural states (solitary and gregarious) whereas grasshoppers generally do not. When the population density is low, locusts behave as individuals, much like grasshoppers.
Both grasshoppers and crayfish are arthropods, a phylum of animals that arose 500 million years ago during the Cambrian period and now comprise 83% of all animal species.
