Conservation
Threats
Introduced species
-
-
-
Species that hybridise eg. indigenous UK red deer threatened by hybridisation with the introduced sika deer
-
Deliberate Eradication
killing of species because they threaten humans or interfere with human activities eg.
- sharks, poisonous snakes, crocodiles
- pathogen vectors eg. malaria mosquitos
- predators of livestock eg. wolves, birds of prey
- agricultural pests eg. insects, birds
-
Direct exploitation
-
-
Fashion - eg.
- fur coats from leopards and tigers,
- leather bags and shoes from crocoiles and aligators
Pets and entertainment - eg.
- (pets) parrots, lizards, snakes, tortoises, tropical fish etc.
- marine life centers - dolphins and orcas usually caught in the wild

Importance
Physiological research
-
eg. studying squid nerves to better understand heart disease, alzheimer's disease etc., as they are much larger and easier to study than smaller, human nerves
Biomimetics
using the knowledge of species adaptations to improve the designs of manufactured structure and equipment
eg. the 'gherkin' structure is based off the external skeleton of a marine sponge - the ventilation system is based on the cirulatory system for water in the sponges
Ecosystem services
-
- Atmospheric composition - photosynthesis, aerobic respiration
- hydrological cycle - transpiration
- biogeochemical cycles - microbes eg. bacteria, fungi
- soil maintenance
- interspecies relationships - no species can live in ecological isolation because their survival relies on other species for resources and ecological services eg. food (heterotrophs), pollination, seed dispersal, habitat provision
Resources
-
Genetics
-
Introduced characteristics:
- disease or pest resistance
- drought resistance
- high yield eg. oil palm yields have increased 25% by cross breeding with wild varieties of central africa
- improved marketability
etc.
