Influence of Elevation, Land Use, and Landscape Context on Patterns of Alien Plant Invasions along Roadsides in Protected Areas of South-Central Chile

Article Abstract:

Land use and elevation were found to explain 74% of alien plant species richness variation in Chile's temperate Andean region. Disturbed secondary forests and pasture transects showed higher presence of alien species. Road corridors are identified as the primary means of alien species introduction; implications for conservation strategy are discussed.

Predicting future threats to the native vegetation of Robinson Crusoe Island, Juan Fernandez Archipelago, Chile

Article Abstract:

The article assesses invasive plant species dynamics on Chile's Robinson Crusoe Island and their impact on native vegetation. Logistic regression was used to assess historical and recent map data; findings indicate that invasive species could replace 50% of native forest in approximately 80 years if conservation measures are unsuccessful.

Conservation implications of a newly discovered bee species on Isla Robinson Crusoe, Chile

Article Abstract:

Bee samples collected on Isla Robinson Crusoe in 1980 and 1981 are studied in detail and compared with other members of the genus Lasioglossum subgenus Dialictus from adjacent continental Chile. It remains to be seen whether an effort has to be made to encourage or eliminate the new, and adventive, Lasioglossum on Isla Robinson Crusoe.
