    There has been a major genetic depression in the Florida Panther. Previously, panthers mated with pumas in Texas and Eastern regions because their ranges overlapped. The exchange of genetic material kept the subspecies healthy. Yet, because the Florida Panther has been reduced to the southern tip of Florida, inbreeding has led to heart deformities, low sperm count, malformed sperm, and cyrptorchidism. The Florida Fish and Wildlife Conservation Commission (FWC) held the genetic restoration program with the introdution of eight Texas pumas into the population. By 2001, five of pumas mated with panthers which produced 30 kittens. Genetic restoration helped gene flow and reduced problems with inbreeding. Now, there are fewer than 100 panthers.
    Intraspecific Agression is a natural behavior involving competition between males for range territory. It results in death and injury. Habitat protection has to be implemented to stop this competition. Although this is a natural behavior, the major problem is linked to continued habitat loss due to development. The male is compteting to survive in his shrinking habitat. Since 2001, numbers of males killing females have rised because male home ranges have overlapped with female home ranges.
    The Florida Panther is also exposed to much pollution from suburban, industrial, and agricultural industries. As top predator, the Florida Panther gathers mercury in its system. Panthers are exposed to mercury through the food they eat, including racoons, who acquire it from crayfish they eat. In 2004, Florida health officials released 172 state rivers and lakes contain mercury which harm the animals and the community. Mercury poisoning has been the cause of death for 3 panthers.

    Like our own Endangered Species Act, there have been conservation attempts for the Ridgway's Hawk.
    The biggest threat is one that is most common among the endangered species list, loss of habitat. There is a lot of pressure to convert the national park into agricultural land, which is it's natural habitat.
    The Ridgway's Hawk belongs in the family of birds of prey, scientifically called falconiformes, that are theorized to have evolved from dinosaurs, more specific, raptors.

    Discription:
    The Ridgway's Hawk is a medium-sized, with a 36–41 cm long wing span. This hawk is named after the ornithologist Robert Ridgway. The adult hawk has brown-grey upper feathers, grayish barred under feathers, and a black-and-white barred tail. This bird of prey feeds on small mammals, birds, lizards and snakes. It nests in the crowns of tall trees in Los Haitises National Park in the northeastern Dominican Republic, which is mostly covered by wet limestone forest. This bird is critically endangered due to clearance of its forest habitat and persecution by local farmers, who erroneously believe the species preys on domestic fowl, even though reptiles comprise up to 90% of its diet.

    Scientific Info:
    Intensive research of the species’ breeding ecology and conservation genetics are part of an ongoing study initiated in 2005, and annual surveys are conducted to monitor the population within the Park (53 active nests monitored in 2007). Ongoing DNA work is comparing the extent of genetic variation remaining in the current population with the historical population to determine if poor genetic diversity should be a concern for species recovery. Ongoing monitoring at Los Limones in the east of Los Haitises National Park shows a 5-10% annual decline in the number of individuals at this site, equating to a decline over ten years of 40-65%. Declines in the west of the park are expected to be continuing at a similar, although perhaps slower rate, hence overall rates of decline are perhaps best estimated to fall within the band 30-50% over ten years. However, forest clearance within the park boundary remains rapid with an annual loss of c.10-15%, thus careful monitoring is a priority and it may reveal that a higher rate of decline is occurring (Woolaver, 2007). Most closely related to B. lineatus (Wiley and Wiley 1981), from which it is probably derived, but also close to B. nitidus (= Asturina nitida), B. platypterus, and B. magnirostris. Some have suggested that the species in this group are closer to Leucopternis than to Buteo (Bierregaard 1994). Although this species appears to prefer undisturbed forest foothills, it has actually been reported from a wide variety of habitats, including rainforest, subtropical dry and moist forests, pine forest, limestone karst forest, and even in second-growth woodlands and agricultural areas from sea level to 2,000 m (Wiley 1986, Keith et al. 2003, Thorstom et al. 2007).
