An Apparently Rare Hybrid between Baikal Teal and Commom Teal newly obtained in Japan

Specimen Shrinkage in Cinnamon Teal

—Body size measurements from freshly collected birds and dried museum specimens were used to evaluate specimen shrinkage in Cinnamon Teal (Anas cyanoptera). Six of seven body measurements of female Cinnamon Teal differed significantly after specimen drying, whereas five of seven male body measurements differed. The largest amount of shrinkage was in bill height, bill width, and tarsus length. B...

Improving Student Understanding with TEAL

Introduction O ver the last three years, the MIT Physics Department has been introducing major changes in the way that 8.02, Electromagnetism I, is taught at the Institute, through the TEAL (Technology Enhanced Active Learning) Project [Supported by the d'Arbeloff Fund for Excellence in MIT Education, the MIT/Microsoft iCampus Alliance, the MIT School of Science, and NSF] (Belcher 2001). After ...

Teal fluorescent proteins: Characterization of a reversibly photoswitchable variant

Fluorescent proteins (FPs) emerged in the mid 1990s as a powerful tool for life science research. Cyan FPs (CFPs), widely used in multicolor imaging or as a fluorescence resonance energy transfer (FRET) donor to yellow FPs (YFPs), were considerably less optimal than other FPs because of some relatively poor photophysical properties. We recently initiated an effort to create improved or alternat...

Genetic analysis of brown teal (Anas chlorotis) from Fiordland

Taxonomic status of the brown teal (Anas chlorotis) in Fiordland

Mitochondrial 12S rRNA sequence data were used to examine the taxonomic status of the endemic brown, Auckland Island, and Campbell Island teal. Based on phylogenetic reconstructions using the 12S rRNA data we have found that the Great Barrier Island brown teal, and the Auckland and Campbell Island teals form a discrete clade, to the exclusion of the Fiordland brown teal. All of the Fiordland br...
