automatic flyproof latrine seat, a few points about fly-breeding will not be out of place. These points actually drew my attention to the necessity for an automatic device which I think is essential in dealing with the problem. There is a general belief that fly-breeding occurs mainly in manure and rubbish heaps, and consequently efforts are made to stop breeding in such materials rather than i...

Studies on culicid breeding in empty rice fields were carried out during the cultivation cycle from May to November 1993. This period corresponded to stages 1 and 2, when empty conditions prevailed. Breeding occurred in stage 1 and the first part of stage 2, corresponding respectively to fallow uncultivated and ploughing situations. No breeding was found to take place during the second part of ...

In South Africa, most adult African penguins molt between September and January; at Namibia’s Mercury Island, most molt in April and May. Throughout their range most immature birds molt between November and January. The season of breeding varies between colonies but at each takes place when food is likely to be most abundant nearby. The main molt of adults occurs when food is least available ne...

In response to climate warming, a southward shift in productive frontal systems serving as the main foraging sites for many top predator species is likely to occur in Subantarctic areas. Central place foragers, such as seabirds and pinnipeds, are thus likely to cope with an increase in the distance between foraging locations and their land-based breeding colonies. Understanding how central plac...

To the Editor, The Indian Medical Gazette Sir,?In your January 1938 number, Mr. MSyddiq has published a short resume of the life his ^ of the eye-fly, S. funicola. It is however necessary mention that Jepson and Pinto (1927), in the Government Agricultural Service, have studied the life history, and bred the flies artiftci ^ on a variety of dead organic matter: they lived ^ much as six weeks in...

Colonial breeding is an evolutionary puzzle, as the benefits of breeding in high densities are still not fully explained. Although the dynamics of existing colonies are increasingly understood, few studies have addressed the initial formation of colonies, and empirical tests are rare. Using a high-resolution larval drift model, we here document that the distribution of seabird colonies along th...
