Manatee counts are highly variable without an accurate way to estimate numbers. In Florida in 1996, a winter survey found 2,639 manatees; in 1997, a January survey found 2,229, and a February survey found 1,706. [20] A statewide synoptic survey in January 2010 found 5,067 manatees living in Florida, the highest number recorded to that time. [43]
Fishing nets and lines can cause injuries to manatees that can lead to serious infections. Studies have shown that around 14% of manatees since 1978 have been found with debris in their GI tract which mainly consisted of fishing lines. Some manatees have also been shown to have missing or scared fins due to their entanglement in these fishing ...

Everyone likes manatees. Except, perhaps, for whoever scraped "TRUMP" into a manatee in 2020. Manatee populations have recovered significantly over the last few decades, after hunting and habitat ...
Joseph Connell published his hypothesis in 1970 in Dynamics of Populations. [2] Unlike Janzen, Connell proposed experiments that focused on the key prediction that exclusion of host-specific predators would cause a decrease in diversity as tree species with greater establishment or competitive ability formed low-diversity seedling and sapling communities where dominance was concentrated in a ...
The dugong (/ ˈ d (j) uː ɡ ɒ ŋ /; Dugong dugon) is a marine mammal.It is one of four living species of the order Sirenia, which also includes three species of manatees.It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
