Rates of evolution on the time scale of the evolutionary process
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-11)
A generational time scale, involving change from one generation to the next, is the time scale of evolution by natural selection. Microevolutionary and macroevolutionary patterns reflect this process on longer time scales. ...
Testing a simple stochastic model for the dynamics of waterfowl aggregations
(Springer-Verlag, 2001-08)
We consider a simple stochastic model for the dynamics of mixed-species waterfowl aggregations and describe two methods for assessing the fit of this model to field data. The model does not incorporate species-specific ...
Sensory responses of descending brain neurons in the walking cricket Gryllus bimaculatus
(Springer-Verlag, 2001-02)
Sensory responses of various descending brain neurons, their modulation during standing or walking, and the correlation of such modulations with stimulus category were investigated. Stimuli involving (1) static or moving ...
Fluorescence-based biosensing of zinc using carbonic anhydrase
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-09)
Measurement of free zinc levels and imaging of zinc fluxes remains technically difficult due to low levels and the presence of interfering cations such as Mg and Ca. We have developed a series of fluorescent zinc indicators ...
Signaling through the CLAVATA1 receptor complex
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-07)
Identification of members of the Wnt signaling pathway in the embryonic pituitary gland
(Springer-Verlag; Springer-Verlag New York Inc., 2001-11)
Prop1 is one of several transcription factors important for the development of the pituitary gland. Downstream targets of PROP1 and other critical pituitary transcription factors remain largely unknown. We have generated ...
Determining the sources of calcium for migratory songbirds using stable strontium isotopes
(Springer-Verlag, 2001-02)
We investigated natural variations in the stable isotopic composition of strontium (a surrogate for calcium) in the bones of a single species of breeding migratory songbird, as well as in their eggshells, egg contents, and ...
Fine-root biomass and fluxes of soil carbon in young stands of paper birch and trembling aspen as affected by elevated atmospheric CO 2 and tropospheric O 3
(Springer-Verlag, 2001-07)
Rising atmospheric CO 2 may stimulate future forest productivity, possibly increasing carbon storage in terrestrial ecosystems, but how tropospheric ozone will modify this response is unknown. Because of the importance of ...
Genomic characterization of human SEC14L1 splice variants within a 17q25 candidate tumor suppressor gene region and identification of an unrelated embedded expressed sequence tag
(Springer-Verlag; Springer-Verlag New York Inc., 2001-12)
Human SEC14L1 shows partial sequence homology to the budding yeast SEC14 protein and the Japanese flying squid retinal-binding protein and was previously generally localized to 17q25. We more precisely mapped SEC14L1 within ...
Letter to the Editor: 1H, 15N and 13C assignments of the N-terminal domain of Yersinia outer protein H in its apo form and in complex with a phosphotyrosine peptide
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-09)
