Connor et al. (2022) published an article in Tree Physiology (https://doi.org/10.1093/treephys/tpac150). Based on the data presented in Figure 5, evaluate the hypothesis that elevated atmospheric CO₂ can reduce the negative effects of drought on woody plant growth. In your response: Describe the overall trends in biomass across the CO₂ and water treatments. Determine whether all four species respond similarly to elevated CO₂ and explain your reasoning using evidence from the figure. Propose a physiological mechanism that could explain why elevated CO₂ influences plant growth under water-stressed conditions. Predict how these results could affect the future abundance of woody plants in rangeland ecosystems under climate change scenarios. Figure 5 Tissue specific biomass proportion for each of the woody species (Cornus drummondii, Gleditsia triacanthos, Juniperus osteosperma, Rhus glabra) based on the experimental treatments.

A nurse is caring for a 72-year-old postoperative patient who reports nausea and requests medication. The patient is drowsy after anesthesia and has the following assessment findings: BP: 108/64 mmHg HR: 88 bpm RR: 12 breaths/min SpO₂: 94% on room air Current IV fluids: Lactated Ringer’s at 75 mL/hr Orders: Ondansetron 4 mg IV PRN every 6 hours for nausea Promethazine 12.5 mg IV PRN every 6 hours for nausea The nurse decides to administer ondansetron instead of promethazine. Which clinical reasoning best supports the nurse’s decision?

Liu et al. (2024) published an article in Current Biology (https://doi.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.
