Differences between the California chaparral and Chilean matorral are more profound than previously thought and are due not only to different degrees of human disturbance, but also to the presence of periodical natural fires in California and not in Chile, and to different shrub recruitment patterns and mammalian herbivore activity in the two areas.

Field and experimental evidence is shown that introduced herbivores and soil degradation strongly influence the distribution of introduced herbs in the Chilean matorral and several factors that might explain why alien herbs are more successful in the Chile matorrals than in the Californian chaparral are discussed.
Does fire induce shrub germination in the Chilean matorral
Field measurements and experiments indicated that at depths where the seed bank is located temperatures are high enough to kill all seedlings and there are no places where temperatures are comparable to those usually used in laboratory to verify germination enhancement by high temperatures.

ECOLOGICAL CONVERGENCE OF LIZARD COMMUNITIES IN CHILE AND CALIFORNIA
- E. Fuentes
- Environmental Science
The hypothesis of convergence in community structure was investigated using taxonomically unrelated lizard communities in Mediterranean climatic areas in central Chile and southern California, and range of resources used as well as utilization functions of individual species were more similar in equivalent sites in the two continents than in nearby Sites in the same continent.

Vegetation change in large clearings: Patterns in the Chilean matorral
It is concluded that nursing by older shrubs and not by rocks or fallen branches, is a requirement to insure the survival of seedlings belonging to mature matorral shrubs.
Latitudinal Size Variation of Chilean Foxes: Tests of Alternative Hypotheses
There are only 2 species of canids in mainland Chile: the foxes Dusicyon (ulpaeus and Dusicyon griseus. These 2 species are shown to diverge in body size with increasing latitude: body size of D.…

European rabbits versus native rodents in Central Chile: effects on shrub seedlings
It was found that degus cause important seedling mortality only within a 5 m-radius centered at the border of their retreats, and it is speculated that rabbits may be halting the secondary succession process, shifting the matorral composition toward less palatable shrub species, and/or broadening the spacing between shrub clumps.
