Generalists vs Specialists | Ecology & Environment | Biology | FuseSchool

Learn about the benefits and the drawbacks of adapting to very specific conditions (specialists) or a broad range of conditions (generalists). 00:00:03,990 -- 00:00:10,090 Within an ecosystem organisms can be 00:00:07,270 -- 00:00:13,960 categorized into two groups specialists 00:00:10,090 -- 00:00:16,000 and generalists. Generalists are the 00:00:13,960 -- 00:00:18,189 species that can live in a wide range of 00:00:16,000 -- 00:00:20,550 environmental conditions and utilize a 00:00:18,189 -- 00:00:22,449 wide range of resources for example 00:00:20,550 -- 00:00:24,369 generalists may be able to tolerate a 00:00:22,449 -- 00:00:29,019 wide range of temperatures or have a 00:00:24,369 -- 00:00:30,880 varied diet. Specialists are the opposite 00:00:29,019 -- 00:00:34,960 they can only survive within a narrow 00:00:30,880 -- 00:00:36,400 range of parameters for example some 00:00:34,960 -- 00:00:38,830 plants may be reliant on a certain 00:00:36,400 -- 00:00:41,379 amount of rainfall or an animal may feed 00:00:38,830 --00:00:45,549 exclusively on one species. They have a 00:00:41,379 --00:00:47,710 specialized ecological niche because 00:00:45,549 -- 00:00:49,809 specialists are adapted to more specific 00:00:47,710 -- 00:00:51,699 conditions than generalists they do not 00:00:49,809 -- 00:00:55,409 cope well with environmental change and 00:00:51,699 -- 00:00:57,820 they are more likely to go extinct 00:00:55,409 -- 00:01:02,170 generalist cope better because they can 00:00:57,820 -- 00:01:03,879 adapt when the environment changes the 00:01:02,170 -- 00:01:05,950 advantage that specialists do have is 00:01:03,879 -- 00:01:07,750 that they can compete much better with 00:01:05,950 -- 00:01:09,039 other species because they are highly 00:01:07,750 -- 00:01:10,750 adapted to their niche 00:01:09,039 -- 00:01:15,009 whereas generalists are easily out 00:01:10,750 -- 00:01:17,439 competed. Koala bears are a special 00:01:15,009 -- 00:01:21,219 species because they almost exclusively 00:01:17,439 -- 00:01:23,109 eat eucalyptus if the eucalyptus was to 00:01:21,219 -- 00:01:25,350 become extinct then it is likely that 00:01:23,109 -- 00:01:28,270 the Koala would also become extinct 00:01:25,350 -- 00:01:33,520 humans are generalist species because we 00:01:28,270 -- 00:01:35,920 almost anything. To summarize donor 00:01:33,520 -- 00:01:38,380 elicits that's easily and they tolerate 00:01:35,920 -- 00:01:40,149 environmental change they survive in a 00:01:38,380 -- 00:01:42,159 wide range of environmental conditions 00:01:40,149 -- 00:01:44,439 and they can utilize a large selection 00:01:42,159 -- 00:01:47,740 of resources and habitats but they are 00:01:44,439 -- 00:01:49,420 easily out computed specialists on the 00:01:47,740 -- 00:01:51,310 other hand, they are more vulnerable to 00:01:49,420 -- 00:01:54,969 extinction because they don't tolerate 00:01:51,310 -- 00:01:57,100 environmental change: They have a 00:01:54,969 -- 00:01:58,539 specialized ecological niche so well 00:01:57,100 -- 00:02:02,700 suited to a narrow range of conditions 00:01:58,539 -- 00:02:02,700 and they are really great competitors SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.
