Question

2) There are 5 threat factors that must be considered when determining recovery threats, but not all of the threats are of concern for manatees. Please mark all the ones that are not of concern. - Overutilization for commercial, recreational, scientific, or educational purposes - Presence/threatened destruction, modification, or curtailment of species’ habitat/range - Disease or predation - Other natural or manmade factors affecting species’ survival - Inadequacy of existing regulatory mechanisms

3) True or False: Florida manatees are doing well throughout their range.

4) Which of these acts in NOT considered integral to Florida manatee protection? a) Endangered Species Act of 1973 b) Wildlife Reform Act of 1968 c) Florida Manatee Sanctuary Act of 1978 d) Endangered Species Conservation Act of 1966 e) Marine Mammal Protection Act of 1972

5) Which of the following is incorrect in reference to cold stress syndrome? Pick best answer. a) All answers are correct b) Lymphoid depletion, lymphocytolysis c) May lead to abscesses, pneumonia d) Entercolitis, pancreatic atrophy e) Causes catarhal rhinitis

Answer 1

1. D. The timeline is limitless because there is not a perfect rate at which their number is decreasing or increasing and we cannot tell at whjch point what environmental or human tragedy will cone and affect them. It hapoens suddenly as they were endangered earlier but measures to save them proved useful as their number increased and they were again endangered in 2017. They are now vulnerable due to decreased population.

2. Recreational, educational purposes

Else all are of conceen as threat because tgey effect their survival in one way or other.

3. False.

They are not doing well which is resulting in continuous decrease in their number. Their loss of habitat, that is unavailable warm water during cold months, red tide, Florida's aligators are factors affecting their survival.

4. D. Endangered species conservation act. Else all options are integral to florida.

5. A. All are correct.

Exposure of manatees to cold temperatures for a long duration leads to prsence of clinical signs and disease called cold stress syndrome. It causes lymphoid depletion, lymphocytolysis, abscesses, pneumonia, enterocolotis, pancreatic atrophy, catarhal rhinitis, fat store depletion, myocardial degeneration and immunosuppression.
