MPAs primarily regulate human activities by segregating them spatially. MPAs alone cannot address problems such as pollution, climate change, or overfishing. Other management strategies are needed to complement marine reserves. They are most effective when used in conjunction with other management measures.
Ticks are Everywhere. Ticks are everywhere, which means tick disease is everywhere. In fact, veterinary parasitologist Dr. Michael Dryden of Kansas State University College of Veterinary Medicine calls tick disease an âepidemic.â Tick disease in dogs is a sentinel for people.
In most circumstances, it is not the tick bite but the toxins, secretions, or organisms in the tick's saliva transmitted through the bite that cause disease. Ticks (and mites) are arthropods, like spiders. There are more than 800 species of ticks throughout the world. Many organisms that bite humans for a blood meal are not ticks and should not be confused with ticks. Some common examples are mosquitoes, bedbugs and fleas (these are insects, not arthropods).
