Local extinction events
Heat waves can lead to local extinction in New Zealand (2017-2018) there were hot summers of 18.8 degrees Celsius. Which was 1.2 degrees Celsius above average. This lead to the local extinction of Bull Kelp (Durvillaea spp.) from Pile Bay because of the combination of high air temperature's and small wave height.

Lagoa Santa, Brazil lost almost 70% of the local fish species over the last 150 years. These include Acestrorhynchus lacustris, Astyanax fasciatus, and Characidium zebra. This could be caused by the introduction of non-native species like Talapia rendalli into the lagoon, changes in water level and organic pollution.

Glaciation can lead to local extinction, This was the case during the Pleistocene glaciation event in North America. During this period most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe.

Conservation
Wolves have been a species organism that have been reintroduced into their historical range. This has happened with red wolves (Canis lupus rufus) in the United States in the late 1980's and also grey wolves in Yellowstone National Park in the mid 1990's. There have been talks of reintroducing wolves in Scotland, Japan, and Mexico. Reintroduction of wolves is a controversial subject and there are pro's and con's on each side.
