Population Status, Habitat Dependence, And Reproductive Ecology Of Bahama Orioles: A Critically Endangered Synanthropic Species, Melissa R. Price, Valerie A. Lee, William K. Hayes

Recent elevation of critically endangered Bahama Orioles (Icterus northropi) to species status prompted us to evaluate their population status, habitat use, and breeding ecology. From surveys, we estimated that at least 141 to 254 individuals remain globally, with 90 to 162, 24 to 44, and 27 to 48 individuals remaining on North Andros Island, Mangrove Cay, and South Andros Island, The Bahamas, respectively. Orioles were observed nesting exclusively in anthropogenic habitat (residential and agricultural land), but home ranges also included nearby pine forest and coppice (dry broadleaf forest). Most nests (40 of 46, or 87%) were in nonnative coconut palm …

The Evolution Of Lateralized Foot Use In Parrots: A Phylogenetic Approach, Culum Brown, Maria Magat
Sentience Collection
Cerebral lateralization refers to the division of cognitive function in either brain hemisphere and may be overtly expressed as behavioral asymmetries, such as handedness. The evolutionary history of laterality is of considerable interest due to its close link with the development of human language. Although considerable research effort has aimed at the proximate explanations of cerebral lateralization, considerably less attention has been paid to ultimate explanations. The extent to which laterality is constrained by phylogeny or shaped by ecological forces through natural selection has received little attention. Here, the foot preference of 23 species of Australian parrots was examined to …

Advertisement Call And Distribution Of The Treefrogs Hyla Chrysoscelis And Hyla Versicolor In Virginia, Joseph C. Mitchell, Christopher A. Pague
Virginia Journal of Science
The gray treefrog complex consists of two sibling species that are indistinguishable morphologically, the diploid Hyla chrysoscelis and the tetraploid Hyla versicolor. Identification is possible in the field only by audio recognition of male advertisement call trill rates (pulses/second). During 1979-1983 we evaluated taped calls of these two species taken from 89 populations from throughout Virginia to map their respective ranges and to evaluate differences in call parameters. Hyla chrysoscelis occurs in the Coastal Plain, eastern and southern Piedmont, and in southwestern Virginia. Hyla versicoloroccurs in the Piedmont, Blue Ridge, and Ridge and Valley regions south to Wythe …

Scaphopod Species (Mollusca) Of The Turkish Levantine And Aegean Seas, Bi̇lal Öztürk
Turkish Journal of Zoology
An examination of benthic material collected from different depths (0-875 m) and habitats along the Turkish Levantine and Aegean seas between 1996 and 2008 has resulted in the identification of 819 scaphopod specimens, belonging to 10 species: Antalis dentalis (Linneaus, 1758), Antalis inaequicostata (Dautzenberg, 1891), Antalis panorma (Chenu, 1843), Antalis rossati (Caprotti, 1966), Antalis vulgaris (da Costa, 1778), Fustiaria rubescens (Deshayes, 1825), Entalina tetragona (Brocchi, 1814), Pulsellum lofotense (M. Sars, 1865), Cadulus jeffreysi (Monterosato, 1875), and Dischides politus (S. Wood, 1842). Of these, P. lofotense and C. jeffreysi are new records for the Aegean molluscan fauna and A. panorma and …
