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
