The fisher (Pekania pennanti) is a carnivorous mammal native to North America, a forest-dwelling creature whose range covers much of the boreal forest in Canada to the northern United States. It is a member of the mustelid family, and is the only living member of the genus Pekania. It is sometimes referred to as a fisher cat, although it is not ...
Habitat conservation is the practice of protecting a habitat [47] in order to protect the species within it. [4] This is sometimes preferable to focusing on a single species especially if the species in question has very specific habitat requirements or lives in a habitat with many other endangered species.
The research documented population dynamics of mountain lions in the northern Yellowstone ecosystem inside and outside the park boundary, determined home ranges and habitat requirements, and assessed the role of lions as a predator in the ecosystem. In recent years in other areas of the West, mountain lions have occasionally attacked humans.
The study, published in the journal Biology Letters on Tuesday, found that some wild fish can use visual cues to identify specific humans even when their faces are covered by diving gear.
In order to be considered fully domesticated, most species have undergone significant genetic, behavioural and morphological changes from their wild ancestors, while others have changed very little from their wild ancestors despite hundreds or thousands of years of potential selective breeding. A number of factors determine how quickly any ...
Pygmy hunter-gatherers in the Congo Basin in August 2014. A hunter-gatherer or forager is a human living in a community, or according to an ancestrally derived lifestyle, in which most or all food is obtained by foraging, [1] [2] that is, by gathering food from local naturally occurring sources, especially wild edible plants but also insects, fungi, honey, bird eggs, or anything safe to eat ...
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
In fact, because humans are so abundant, and the areas that need conservation focus are usually areas in which humans share with the target species or habitat, nearly every study using camera traps has ended up with human by-catch. [1] It is not uncommon for researchers to end up with more photos of humans than of their target species. [10]
