Better protection for mangroves with models for successful seedling establishment
Mangrove forests protect coastlines and are important for biodiversity, acting as a nursery ground for many fish species. However, mangrove forests are in danger, not only as established forests, but also as seedlings. Mangrove seedlings can have a difficult time anchoring themselves in the sediment. Natural factors including high tides and erosion can make successful establishment challenging, in addition to manmade issues such as development in coastal areas and climate change. A new study focused on the conditions that allow mangrove seedlings to be successful. By understanding the optimal conditions, times and locations for mangrove establishment, future mangrove restoration efforts will be much more successful.
Fish skin adding new knowledge about the immune system
The immune system of fish resembles that of humans in many ways. Researchers have studied the immune responses in fish skin and mapped the changes that occur in connection with immune diseases in both humans and animals. They found that the immune response is milder when the fish has been in contact with a particular parasite, lessening the effects of illnesses. The researchers were initially studying the easiest way to get rid of two specific parasites that cause problems in the fish farming industry. Now, they are initiating an experiment to try to treat and immune disease in zebrafish using specific parasites.
Seabed mining: 3 days to have your say
Trans-Tasman Resources Ltd (TTR) has filed an application with the Environmental Protection Agency (EPA) to mine the seabed for iron sand off the coast of Patea, South Taranaki, New Zealand. If approved, it would allow the mining of 65 square kilometers for a period of 20 years. The company aims to extract a maximum of 50 million tons of the seabed every year. One group, Kiwis Against Seabed Mining, is fighting against the approval, saying that once one company begins mining, many will follow. Public comments on the issue will be accepted until December 19th.
