In this video, Professor Dicky Clymo gives a valedictory lecture on the importance of bog moss. He explains that these plants have a remarkable lifestyle, covering 4 million square kilometers and producing a quarter of all the organic carbon on Earth. He also points out their importance in wound treatment, noting that they have properties that are ideal for the task.

00:00:00 This video is a recording of Professor Dicky Clymo's valedictory lecture, in which he discusses the importance of bog mosses. He explains that these plants have a remarkable lifestyle, covering 4 million square kilometers and producing a quarter of all the organic carbon on Earth. He also points out their importance in wound treatment, noting that they have properties that are ideal for the task.
00:05:00 Dicky Clymo gives a valedictory lecture on bog moss, which is a dominant plant in wetland and grassland soils. Clymo discusses the structure and functions of bog moss, including its unique ability to photosynthesize and disperse spores. He also looks at the changes that take place during bog moss' life cycle, culminating in the formation of the hiline cell.
00:10:00 This lecture discusses the general response curve for various plants to varying levels of solutes, and how P. gymnocarpa (swagman) can tolerate very low levels of solutes.
00:15:00 In this video, Professor Dicky Clymo discusses the importance of finding suitable habitats for plants, and the role water plays in this process. He also discusses the importance of keeping plants in a place with plenty of light, water, and nutrients. Clymo explains how an experiment was conducted to see if the movement of radioactivity in rainwater was mediated by special structures in the plants, and how electron microscopy was used to study these structures.
00:20:00 In this lecture, Professor Dicky Clymo discusses the basics of cellulose, cotton, and mosses. He explains that cellulose is made of long chains of polyglot uronic acids, and that cation exchange is responsible for the acidity of water. He also notes that egg white, blood, milk, wine, and lemon juice are all slightly alkaline, and that this alkalinity is largely due to cation exchange.
00:25:00 The video discusses Professor Dicky Clymo's valedictory lecture, in which he discusses the physical chemistry behind pH levels and how they can be predicted. Clymo highlights the importance of experiment in learning physical chemistry, and demonstrates how cation exchange can change pH levels in a short amount of time.
00:30:00 This video describes the water cycle and how it affects plants. Professor Dicky Clymo explains that in summer, the water table can go down to 25 centimeters below the average. In autumn, the first heavy rains zip it up again. The lateral branch is the spreading branches allow water to travel sideways between adjacent plants and the pendent branches allow water to travel vertically. The capillary effect in both cases is very effective. The species that grow on hammocks all have lots of pendent branches and tiny leaves. The ones that go further down sometimes have no pendent branches at all. The ones that live in pools this is how the water gets about. The water table can fluctuate a few centimeters on either side, but it drains quickly because the plants are quite porous. From the plants' perspective, the point at which the water table is at (20 centimeters below the average) is important because it corresponds to the water table where they can photosynthesize. When the water table begins to drop, it can come down to 3 times the amount of water of dry matter.
00:35:00 Professor Dicky Clymo discusses the effects of water on mosses and their spores, as well as the sport dispersal of Magnum plants. He also comments on the afterlife of bottles.
00:40:00 Professor Dicky Clymo gave a farewell lecture on the dynamics of peatlands, explaining that the top 20 cm of the soil are permeable to air and allow for the exchange of oxygen and carbon dioxide. This abundant oxygen allows the decay of organic material to run off more easily, leading to the accumulation of gas bubbles and the distribution of the gas into the atmosphere. Clymo also noted that early measurements of gas release from peatlands were made by Jim Read, who is credited with discovering the importance of gas bubbles in peatlands.
00:45:00 Dicky Clymo gives a valedictory lecture on the topic of decomposition. He shows how decomposition occurs in different stages, from surface growth to deep-down decay. He also discusses how decomposition affects the environment and the economy.
00:50:00 Professor Dicky Clymo delivers his final lecture at the university where he has taught for many years. Clymo discusses the principles of decay and how to measure the concentrations of dissolved gases. He demonstrates how to use a quadrupole mass spectrometer to make measurements.
00:55:00 In this video, Professor Dicky Clymo gives a valedictory lecture on the formation of peat bogs. Clymo explains that, in general, peat bogs form when decaying vegetation accumulates over time. The rate of accumulation and decay is determined by the hydrology of the area. In two dimensions, an ellipse is created when the rate of accumulation and decay are equal. Clymo then shows a simulation of a peat bog growing over 10,000 years. The video is repeated because it is a bit complicated to understand.

01:00:00 - 01:05:00

In his valedictory lecture, Professor Dicky Clymo discusses the Bog Magnum, a geological formation that has accumulated a quarter of all the organic carbon on Earth's surface. He describes how decay affects the environment and how knowledge about it has become more difficult to cope with. He also discusses how mass flow and diffusion are two different types of movement, and how they are important for short distances only.
