The indirect threats of invasive species: 1  Changing food webs: Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. 2  The invasive species may provide little to no food value for wildlife.uman health and economies are also at risk from invasive species. The impacts of invasive species on our natural ecosystems and economy cost billions of dollars each year. Many of our commercial, agricultural, and recreational activities depend on healthy native ecosystems.
The common side effect is bleeding. Less common side effects may include tissue death and purple toes syndrome. Use is not generally recommended during pregnancy. It is recommended that the effects of warfarin typically be monitored by checking prothrombin time every one to four weeks.
Background. Overdose of the oral anticoagulant warfarin (Coumadin), or drug interactions with warfarin, can lead to toxicity. Similarly, toxicity can result from exposure to superwarfarins, which are long-acting anticoagulants used in rodenticides.(See Etiology and Prognosis.).leeding is the primary adverse effect of warfarin and superwarfarin toxicity and is related to the intensity of anticoagulation, length of therapy, the patient's underlying clinical state, and use of other drugs that may affect hemostasis or interfere with warfarin metabolism.
