  1. Lutjanus ehrenbergii (Peters, 1869)

    Ketabi, Ramin; Jamili, Shahla
    Lutjanus ehrenbergii is known as Blackspot snapper and Black-spot snapper. L. ehrenbergii is widely distributed in the Indo-West Pacific at depths ranging from 5 to 20 m. This reef-associated species inhabits very shallow coastal habitats, often in large schools near freshwater run-offs. Adults inhabit coral reefs, while juveniles frequent inshore areas over sand, silt or coral rubble bottoms, occasionally in mangrove-lined streams and estuaries. This species may enter freshwater areas to consume small fish and invertebrates. This species reaches sexual maturity at approximately 2 years of age and reaches a maximum age of at least 11 years. Growth trajectories are...

  16. Activity patterns and distribution of Galapagos bats

    Key, Gillian; Sangoquiza, Miguel
    Preliminary studies were carried out on the activity and distribution of the two species of Galapagos bat using heterodyne bat detectors. Monitoring at four sites on Santa Cruz Island from November 2003 to August 2005 revealed no evidence for seasonal migration between the highlands and lowlands for either species. Bat activity was lowest at all sites during December–March and increased over the year. The Hoary Bat Lasiurus cinereus was the commoner of the two species and showed three nightly activity peaks, as determined by all-night monitoring at one site in Santa Cruz Island over a period of three months in 2004. The Red Bat Lasiurus...
