Long-term dynamics (1990 to 2004) of the polychaete fauna from the sublittoral soft-bottoms off Punta Coloso (Antofagasta), northern Chile

open access: yesScientia Marina, 2006
Long-term monitoring (1990 to 2004) at four stations (50 to 60 m depth) off Punta Coloso, Antofagasta, northern Chile, has allowed us to study temporal changes in the sublittoral macrobenthic polychaete infauna composition and abundance.

Benthic assemblages of Polychaeta in chosen regions of the Admiralty Bay (King George Island, South Shetland Islands) [PDF]

open access: yes, 1986
Paper received 15 November 1984.By means of the synthetic diagram method (Romaniszyn 1970) populations of benthic Polychaeta at the depth ranging from 15 to 250 m of the Admiralty Bay (South Shetland Islands) were analysed.

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

open access: yesNano Select, EarlyView.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.

Experience matters: Females use smell to select experienced males for paternal care [PDF]

open access: yes, 2009
Mate choice and mating preferences often rely on the information content of signals exchanged between potential partners. In species where a female's reproduction is the terminal event in life it is to be expected that females choose high quality males ...

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

open access: yesOikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...
