Genetic markers suggest alien fruit fly is using human transport to invade South Africa

The Mediterranean fruit fly, Ceratitis capitata, is a highly invasive species throughout the world and is considered one of the world’s most devastating insect pests. In South Africa, the costs of crop losses and control operations exceed R18 million per annum.

Percent of qualitative/semi-quantitative (a) and quantitative (b) risk assessments considering the different stages of the invasion process, split into models containing different numbers of TEASI components (Transport, Establishment, Abundance, Spread, Impact).

New insights on risks associated with key stages in biological invasions

The human-mediated movement of species around the world has added several layers of complexity to the management of ecosystems. Once alien species are established in a new region they are extremely difficult or impossible to eradicate, and control is expensive and often ineffective.

Dispersal and spread of avian invaders

Following Charles Elton’s pioneering work, invasion ecology has grown into a mainstream research field focusing on the patterns and processes of human-mediated translocation of alien organisms. As probably the most iconic taxa in conservation, birds provide an ideal natural experiment to test many theories and hypotheses in invasion ecology.

Fifteen Antarctic Biogeographic Regions delineated by comparing biologically distinct groups formed by the cluster analyses of environmental domains and expert-defined bioregions.

Conservation Biogeography of Antarctica

Most people think of Antarctica as completely covered in ice. Ice-free areas cover only 0.4 % of the total continental area and until relatively recently it was thought that most were barren and largely devoid of life.
