Journal of Meteorology, 1956 Abstract The correlations of heavy rainfall and of noctilucent clouds with meteor streams are examined with regard to the known facts of meteor astronomy. Photographic and radar observations show that the general influx of sporadic meteors is not greatly enhanced by the occurrence of a meteor stream, and it is unlikely that meteors within the present ...

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil
Animal Conservation, EarlyView.Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

Investigating relationships among strontium, barium, and seasonality in wild baboons
Archaeometry, EarlyView.Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Spectral analysis of four meteors
, 1973 Four meteor spectra are analyzed for chemical composition and radiative processes. The chemical compositions of the Taurid, Geminid, and Perseid meteors were found to be similar to that of a typical stony meteorite.

, 1997 Meteors is a collection of five short stories, each of which illustrates a concern for those who are inarticulate and for that which goes unspoken in everyday speech, for the failure, in other words, of language to adequately communicate.

Late Holocene moisture variability in Arctic Alaska from chitin δ18O
Boreas, EarlyView.Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute
