Vamizi
Spishi nyingi zilizoingizwa katika mazingira mapya haziwezi kuishi katika mazingira yao mapya. Walakini, asilimia ya spishi hizi zina uwezo wa kupanua eneo wanaloathiri na kuathiri vibaya uchumi, afya ya binadamu au ikolojia ya mkoa na inaitwa vamizi. Mabadiliko ya makazi na athari za spishi vamizi zimekuwa sababu kuu ya kutoweka kwa spishi katika miaka mia chache iliyopita, na kuongeza kiwango cha kutoweka kwa karibu asilimia 1,000. Ingawa hapo zamani, hasara hizi nyingi hazijasajiliwa, leo, kuna kuongezeka kwa utambuzi wa gharama za kiikolojia za uvamizi wa kibaolojia kwa sababu ya upotevu usioweza kulipwa wa bioanuwai ya asili na uharibifu wa utendaji wa mfumo wa ikolojia. Ingawa sababu za msingi za vitisho vya spishi vamizi ni muhimu na ya ulimwengu kwa asili, vitisho hivi vinaweza kushughulikiwa vyema kupitia juhudi za kushirikiana katika ngazi za mkoa na mitaa, haswa kupitia kuzuia, kugundua mapema na majibu ya haraka.

5 July 2017 - Removing the flowers of an invasive shrub from mosquito-prone areas might be a simple way to help reduce malaria transmission, according to anew study published in the open access Malaria Journal.Removing the flowers from villages in Mali decreased the local mosquito vector...
- Of all the ways that have been tried to control malaria, one of the easiest could also be among the most effective, a new study suggests. Yet the idea of cutting back on the regular food supply of mosquitoes has been neglected, possibly because it just seemed too simple to work. Malaria is...
