Grassland temperature sum
WebApr 13, 2024 · Grasses using the C 4 photosynthetic pathway are ubiquitous across Earth’s low to mid-latitudes, dominating modern tropical lowland grassland and savannah ecosystems. C 4 grassy biomes play an important role in regulating global climate and have been linked to key adaptations and diversification in mammalian faunas (1–3).The C 4 … WebTemperate grasslands have hot summers and cold winters. Rainfall is moderate. The amount of annual rainfall influences the height of grassland vegetation, with taller grasses in wetter regions. As in the savanna, seasonal drought and occasional fires are very important to biodiversity.
