Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern , insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds, [ 1 ] and many other species navigate effectively over shorter ...
Arthropods like these northern prawn, and some mammals, detect water movement with sensory hairs such as whiskers, bristles or antennae. In animal physiology, hydrodynamic reception refers to the ability of some animals to sense water movements generated by biotic (conspecifics, predators, or prey) or abiotic sources.
No matter what the form of pollution is, the effects water pollution has on animal life can be drastic. For example, the BP oil spill which occurred in 2010 impacted over 82,000 birds, 6,000 sea turtles, approximately 26,000 marine animals, and hundreds of thousands of fish. [27]
Tracking in hunting and ecology is the science and art of observing animal tracks and other signs, with the goal of gaining understanding of the landscape and the animal being tracked (the "quarry"). A further goal of tracking is the deeper understanding of the systems and patterns that make up the environment surrounding and incorporating the ...
The High-Tech Tools Scientists Use to Track Wild Animals Science in recent years has seen an explosion of wildlife tracking-devices that are enabling new insights and scientific breakthroughs.
Grouping may swamp the predator's capacity to capture prey - for example, hawks are unable to capture more than one yellow-eyed junco per attack. [5] Large groups also cause predator confusion as it makes it difficult for prey to focus on one target. [1] Groups of animals may engage in communal defences, such as mobbing, for further protection. [1]
The attraction of huge numbers of prey fish means that these predator species, which might otherwise be mutually antagonistic, usually cooperate with each other in pursuit of their common goal. Bryde's whales often track dolphin groups as they herd prey species. As soon as the dolphins corral the prey, the whales lunge feed through the centre ...
An animal track is an imprint left behind in soil, snow, or mud, or on some other ground surface, by an animal walking across it. Animal tracks are used by hunters in tracking their prey and by naturalists to identify animals living in a given area.
