Self-study module Introduction to Plant Biology - Abiotic stress

This self-study module is part of the series ‘Introduction to Plant Biology’ and introduces abiotic stress in plants and explains how plants cope with and adapt to challenging environmental conditions. It is designed for students learning basic plant biology and for teachers seeking clear figures and explanations for educational use. The module covers key abiotic stresses - heat, cold, flooding, drought, salinity, and high light intensity - and examines the physiological, structural, and adaptive strategies plants use to survive and grow under these conditions.

Example of water and salt balance for a crop

The example is a table explains how a water and salt balance can be made for a crop, to assess the adequacy of a flushing strategy to reduce salts in the soil. The table can be found in the book Drainage Principles and Applications (2006).

Virtual sea-going marine science fieldwork with VirtualShip

Marine science relies heavily on fieldwork at and in the ocean for data collection. Consequently, marine science students need training in sea-going fieldwork. However, such training is expensive, logistically demanding, and environmentally burdensome because research vessels emit substantial amounts of CO₂. To provide students with an opportunity to experience the realities of working at sea, we developed a platform for virtual oceanic fieldwork: the VirtualShip Classroom, which provides Python code, exercises, and 360 videos as virtual reality (VR) covering different aspects of fieldwork such as expedition planning, sampling, and data analysis. Whenever possible, students work with authentic tools and realistic datasets, such as the Marine Facilities Planning platform for designing research expeditions. Basic programming skills are advantageous, particularly when students analyze self-collected data. Students formulate their own research question in a region of the global ocean of their choice. They then investigate this question with a virtual research vessel operated through the bespoke VirtualShip software. Instruments currently implemented for deployment or onboard use are ADCP, CTD, XBT, Argo floats, surface drifters, and underway temperature and salinity sensors. This collection of teaching materials is accompanied by a suggested workflow, which outlines a series of classes on virtual ocean research.
