Liu et аl. (2024) published аn аrticle in Current Biоlоgy (https://dоi.org/10.1016/j.cub.2024.04.062). Examine Figure 1, which shows global patterns of insect herbivory in herbaceous and woody plants. The authors found that herbivory increases with latitude in woody plants but not in herbaceous plants. Provide a biological explanation for why insect herbivory might respond differently to latitude in woody versus herbaceous plants. In your answer: Describe the pattern observed in the figure. Propose at least two ecological or physiological factors that could explain the difference between woody and herbaceous plants. Explain how climate change might alter these patterns in the future. Discuss one limitation of using large-scale global datasets to draw conclusions about plant-insect interactions. Figure 1 Global distribution of herbivory data. (A) The global distribution of 5,924 herbaceous data and 3,858 woody data across the globe. (B) Counts of data in each of the six continents. (C) The location of the sites in relation to the temperature and precipitation envelope.
Mаchаcоvа et al. (2024) published an article in Frоntiers in Fоrests and Global Change (DOI 10.3389/ffgc.2024.1379791). The researchers hypothesized that elevated atmospheric CO₂ would help woody plants tolerate drought stress. Using the data in Table 5, evaluate whether the results support this hypothesis. In your answer: Identify which measured traits were most negatively affected by water stress. Determine whether elevated CO₂ reduced the impact of water stress on these traits. Compare the responses among the species and discuss whether some species appear more responsive to elevated CO₂ than others. Explain the physiological mechanisms that may account for the observed responses. Based on the evidence in Table 5, predict how rising atmospheric CO₂ concentrations could influence future woody plant expansion in rangeland ecosystems.
