Question

The taiga biome has long, cold, dry winters and cool, wet summers. In three to four sentences, describe how the plants and animals would be impacted by a warm and dry summer and how they might survive. Support your answer with the abiotic factors in the biome.(4 points)

Answer 1

Warmer, drier summers (abiotic changes: higher temperatures, lower precipitation, reduced soil moisture and humidity) would stress taiga plants, causing reduced growth, poor seedling survival, higher mortality, and greater wildfire risk. Many conifers might resist short-term drought with needle adaptations, deep or widespread roots, and mycorrhizal water uptake, or by going dormant, but prolonged dryness would favor drought-tolerant species. Animals would face less food and water and more habitat loss, so they might migrate, shift diets, become more nocturnal, use burrows or moist microhabitats, or rely on cached food to survive. Over time these abiotic shifts (temperature, precipitation, soil moisture, fire frequency) would drive changes in community composition toward more drought-adapted organisms.
