While streamflow and soil moisture droughts have been widely studied, groundwater droughts remain underexplored.
Keywords: droughts streamflow soil moisture widely studied groundwater remain underexplored - Soil moisture determines the recovery time of ecosystems from drought (2023) · doi
Recovery time, the time it takes for ecosystems to return to normal states after experiencing droughts, is critical for assessing the response of ecosystems to droughts; however, the spatial dominant factors determining recovery time are poorly understood.
Keywords: time recovery ecosystems droughts takes return normal states experiencing critical assessing response spatial dominant factors - A global transition to flash droughts under climate change (2023) · doi
However, there is no consensus on whether flash droughts have become the new normal because slow droughts may also increase.
Keywords: droughts there consensus whether flash become normal slow increase - Drought in intermittent river and ephemeral stream networks (2021) · doi
Studies on ecological responses to drought in IRES networks are still rare and limited to a few climatic zones and organisms and mainly explored in perennial sections.

Yet to date, the response of ecosystems during flash drought events, particularly on a large scale, and the determinants of the ecosystem responses to flash droughts have been underexplored.
