Avian higher level biogeography: Southern Hemispheric origins or Southern Hemispheric relicts?

Reply or Interannual Southern Hemispheric Atmospheric Variability in the NCEP reanalysis between 1980 and 2002

Climate Variability in the Southern Hemisphere is receiving increasing attention due to both the large greenhouse gas forced response that many climate model exhibit in polar regional impacts of the SAM in a coarse resolution coupled climate model. The overwhelming dominance of this mode in the model's oceanic, sea ice and atmospheric interannual to decadal variability led us to the hypothesis ...

Hemispheric differences in avian song discrimination.

Auditory input to the right or left forebrain of adult male zebra finches (Taeniopygia guttata) was disrupted by lesioning the ipsilateral auditory relay nucleus of the thalamus. These birds were then presented with two kinds of auditory discriminations: (i) between their own song and the song of a cage mate; (ii) between two versions of an unfamiliar zebra finch song that differed only in the ...

Influences of the Antarctic Ozone Hole on Southern Hemispheric Summer Climate Change

Over the past three decades, Antarctic surface climate has undergone pronounced changes. Many of these changes have been linked to stratospheric ozone depletion. Here linkages between Antarctic ozone loss, the accompanying circulation changes, and summertime Southern Hemisphere (SH) midlatitude surface temperatures are explored. Long-term surface climate changes associated with ozone-driven cha...
