Fuente: M. Barahona; S. A. Navarrete.

In this study, we quantified seasonal and spatial variation in displacement (net changes in location in 12 or 24 h periods) and prey consumed of marked individuals of the keystone seastar Heliaster helianthus.

Fuente: S. A. Navarrete; J. L. Shinen.

In this study, we define patterns of local distribution and recruitment of two common intertidal chthamalid barnacles (Jehlius cirratus and Notochthamalus scabrosus) at 15 sites along the shore of central Chile.

Fuente: S. A. Navarrete; S. Gelcich; J. C. Castilla.

Long-term monitoring plays a fundamental and irreplaceable role to establish general baselines from which we can better address current and future impacts and distinguish between natural and anthropogenic changes and fluctuations.

The mosses reported in this paper are the result of an earlier study on the moss flora of the Bío-Bío Region. Identifications of more of the collections made during this period, plus some recent ones (2006–2010).

Reproductive biology of blacknecked Swans Cygnus. melancoryphus at three Chilean. wetland areas and feeding. ecology at Rio Cruces.
Fuente: R. P. Schlatter; J. Salazar; A. Villa; J. Meza.

Reproductive biology o f Black-necked Swans has been monitored at three sites in Chile, Laguna El Peral, Laguna Torca and Rio Cruces. The eight pairs at El Peral have produced 4.2 cygnets/pair in three seasons, but chick mortality has been 83 % due to territoriality and aggressive interactions.
