Osprey were most susceptible because they were higher up the food chain.
*DDT runoff into streams *Minnows, crayfish, insects consumed some *Small fish ate those creatures, and so got an additive dose of all the DDT they were carrying *Larger fish ate the smaller ones and, again, the DDT load of each smaller fish added to that *Osprey consume large fish. THUS the osprey, as an end predator consumed the most DDT. Factor in that, the higher up the food chain you go, the fewer individuals there are.
The DDT made the eggshells fragile, so fewer osprey were hatched. So their numbers were reduced even more in comparison to those organisms that were more abundant to begin with.
What else can I help you with?
What was an animal which wasn't affected by DDT?
Cockroaches.
What trophic level is most affected by environmental toxins such as DDT?
The trophic level most affected by environmental toxins such as DDT is usually the top predators, such as apex predators or carnivorous animals. This is because toxins bioaccumulate as they move up the food chain, reaching higher concentrations in organisms at higher trophic levels.
What animal population was not affected by an increase is the krill population?
There are a couple of animal populations that were not affected by an increase is the krill population. Cobras were not affected.
Is DDT illegal?
The use of DDT was banned in the USA in 1973 although it is still in use in some other parts of the world
What are the effects of DDT on marine mammals?
Bio-accumulation in the invertebrates within the aquatic ecosystem makes it highly toxic to larger predators such as species of fish and possibly feeding birds in the aquatic area. DDT effects the fertility of the species such as thinning of egg shells and death of embryos.
What raptors are affected by DDT?
ALL raptors are affected by DDT, because they prey upon what's been poisoned. Check out the related link listed below:
Why did ddt only affect to carnivores?
Not true. Birds have been affected by DDT and so have fish.
What was an animal which wasn't affected by DDT?
Cockroaches.
Did DDT affect the osprey?
Yes, DDT (dichloro-diphenyl-trichloroethane) significantly affected the osprey population. The pesticide led to the thinning of eggshells, resulting in reduced hatching success and declining osprey numbers. As a result of these adverse effects, DDT use was banned in many countries, contributing to the recovery of osprey populations in subsequent years.
Can DDT cause malaria?
No, DDT does not cause malaria. DDT is actually used to control the mosquito populations that spread malaria by killing the mosquitoes that carry the disease. Using DDT in a controlled and targeted manner can help reduce the incidence of malaria.
What are the populations affected by humans in the saguaro national park?
what are the populations affected by humans???
What animal was affected by the use of DDT to point of becoming an endangered species?
The Bald Eagle, and other raptors such as the Peregrine Falcon, and Osprey populations were devastated by DDT. The long term exposure nearly wiped them out. Many other birds were affected as well, Robins in one instance were killed outright on a campus when the trees were sprayed to protect them from a disease. But the raptors suffered the worst exposure, the DDT stayed in the food chain creating a domino effect, so they ingested it in greater quantities. For more details, please see the sites listed below.
What has the author John Albert Gill written?
John Albert Gill has written: 'Tolerance of two populations of ring-necked pheasants to DDT' -- subject(s): DDT (Insecticide), Ring-necked pheasant
How can the use of DDT actually boost an insect population?
The selective use of DDT can kill off predators or parasites that control insect populations, leading to an increase in the target insect species. This disruption in the natural balance can result in a population surge.
How did DDT affect otters?
DDT, a pesticide widely used in the mid-20th century, had detrimental effects on otters, primarily through the contamination of their aquatic habitats. The chemical accumulated in the food chain, leading to reproductive issues and decreased survival rates in otters due to thinning of eggshells and other health problems. As a result, otter populations declined significantly in areas where DDT was heavily used, highlighting the broader environmental impacts of this pesticide. The ban on DDT in many countries has since allowed for some recovery of otter populations.
Why are 2nd order consumers are more likely to be affected by the DDT than the 1st order consumers?
BIOACCUMULATION
What scientific studies support the decision to ban DDT?
Scientific studies have linked DDT exposure to various health and environmental issues, including adverse effects on wildlife, such as the thinning of eggshells in birds. The toxicity of DDT and its persistence in the environment have raised concerns about its impact on ecosystems and human health, leading to bans in many countries to mitigate these risks.
