Gibberellic acid (GA3) is a plant hormone that was first isolated from the fungus Gibberella in Japan in the 1930s. It was found to promote plant growth activity. Gibberellic acid has since been isolated from a variety of different plant types, ranging from beans to tobacco.
When does the future start with regards to the ocean? Rising sea levels, ocean acidification, and overfishing are problems that the ocean faces right now. An ocean full of jellyfish is a probable future. Jellyfish can be very beautiful with their movements and bioluminescence and have an interesting life cycle.
The number of different evolutionary pathways available to populations adapting to a new environment depends on the range and characteristics of possible genetic solutions. Even populations adapting to the same environmental challenge can diverge genetically from each other if different mutations happen to establish. The long-term impact of this initial divergence depends on the fitness interactions between the available alleles that underlie adaptation to a given environment (“epistasis”).
Well-built seawalls have long been used as an inexpensive way to control coastal erosion. Seawalls are associated with reduced aesthetic value, and increased erosion at the ends and in front of the seawall.
How does the reduction of Arctic Sea ice directly impact the habitat of human beings? In this paper, we discuss the myriad ways that the Arctic sea ice could potentially harm human beings by reducing certain animal habitats that are used for subsistence.
