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

A warmer, drier summer would raise temperatures and lower precipitation and soil moisture in the taiga, stressing cold‑adapted conifers and slowing growth or causing increased mortality, while also making the forest floor drier and more prone to wildfires and pest outbreaks. Animals would face reduced food and water availability, loss of insulating canopy/cover, and lower reproductive success as insects, berries and young plants become scarcer. Plants might survive by relying on drought‑tolerant traits (deep or widely spaced roots, reduced needle area, thick bark) or by regenerating from seeds after fire and via mycorrhizal networks that help with water uptake. Animals could cope by shifting ranges northward or to higher elevations, using riparian or bog refuges with more stable moisture, becoming more nocturnal or mobile, or altering diet and breeding timing to match the changed abiotic conditions.
