| Management actions to protect endangered species and conserve ecosystem function may not always be in precise alignment. Efforts to recover the California Ridgway’s Rail (Rallus obsoletus obsoletus; hereafter, California rail), a federally and state-listed species, and restoration of tidal marsh ecosystems in the San Francisco Bay estuary provide a prime example of habitat restoration that has conflicted with species conservation. On the brink of extinction from habitat loss and degradation, and non-native predators in the 1990s, California rail populations responded positively to introduction of a non-native plant, Atlantic cordgrass (Spartina alterniflora). California rail populations were in substantial decline when the non-native Spartina... |

| Data on macrofauna density and diversity, and the height and density of Spartina brasiliensis, were obtained from salt marsh beds of a tropical estuary in northern Brazil. Sampling was carried out at four distinct times of the year, during the wet and dry seasons and in the transition periods between these. Sampling was also carried out in salt marshes of three size classes, small, medium and large. Variables were analyzed in relation to time of year and salt marsh size class. Overall, 46 taxa were found, with polychaetes, isopods and the gastropod Neritina virginea dominating the fauna. Macrofauna density and diversity were positively correlated with culm density, indicating a possible role in protection from predation. All the three variables were higher... |

| Se desarrolló un protocolo de desinfección y regeneración in vitro de Spartina argentinensis. El menor porcentaje de contaminación se obtuvo tratando los cariopses por 60 s en etanol 90° y 20 min de inmersión en hipoclorito de sodio al 2,5% con Tween 20. La inducción de callos se realizó en medio Murashige y Skoog (MS) suplementado con 0,5 mgL-1 de ácido diclorofenoxi acético (2,4-D) y 1 mgL-1 de ácido indol acético (AIA). La mayor (20%) regeneración de vastagos se logró con igual base salina y 0,25 mgL-1 de bencilamino purina (BAP). Se utilizó 0,025 mgL-1 de ácido naftalen acético para la regeneración de raíces. Las plantas se regeneraron vía organogénesis. Este protocolo es la primera mención de regeneración de plantas de S. argentinensis utilizando... |
