Cepheids as Distance Indicators: Some Current Problems

A general review is given of the calibration of the Cepheid distance scale, with particular reference to its use in the determination of H0. Emphasis is placed on the advantage of using a galactic calibration of the Cepheid scale, rather than relying on an adopted distance to the LMC. It is then possible to use LMC data to test for possible metallicity effects on this scale.

Global Conservation Priorities for Marine Turtles

Where conservation resources are limited and conservation targets are diverse, robust yet flexible priority-setting frameworks are vital. Priority-setting is especially important for geographically widespread species with distinct populations subject to multiple threats that operate on different spatial and temporal scales. Marine turtles are widely distributed and exhibit intra-specific variat...

Seabirds as indicators of marine food supplies: Cairns revisited

In his seminal paper about using seabirds as indicators of marine food supplies, Cairns (1987, Biol Oceanogr 5:261–271) predicted that (1) parameters of seabird biology and behavior would vary in curvilinear fashion with changes in food supply, (2) the threshold of prey density over which birds responded would be different for each parameter, and (3) different seabird species would respond diff...

Marine Animals Chaetognatha as Bio-indicators of Geophysical Activity

A study was done on the morphology of marine planktonic animals, Chaetognatha (arrow worms), taken during sea expeditions from the regions without the influence of geophysical activity, from shallow-water volcanic bays and deep-water geophysically active regions. It was discovered that among the chaetognaths from geophysically active regions there was a large number of animals (up to 95%) with ...
