Abstract:
Populations of Hydra pseudoligactis were censussed during 1980–1981 in a lake and a small pond in southern Québec. Both natural and artificial substrates (glass slides) were used. Population density rose during the early part of the season to a maximum in June–July, after which a decline in the rate of asexual budding drove density down. The decline in budding rate lagged about 2 weeks behind the increase in density. High local population density on the glass slides reduced rates of budding and caused dispersal from crowded slides. Sexual individuals appeared in the middle of the growing seaso

Abstract:
AbstractThe fresh water polyp Hydra is noted for its ability to regenerate missing body parts. Transplantation experiments indicate that the control of regeneration includes signalling over long distances. These signals appear to include diffusible morphogens, activators and inhibitors. In order to elucidate the nature of such signals, tissue of polyps was homogenized and fractionated. The fractions were tested for their ability to hinder head regeneration. The active factor within these fractions was determined to be methionine. Both the active fractions and L-methionine were found to antagon

Abstract:
A homologue of the T-box gene, Brachyury, has been isolated from hydra. The gene, termed HyBra1, is expressed in the endoderm and is associated with the formation of the hypostome, the apical part of the head in four different developmental situations. In adults, which are continuously undergoing patterning, HyBra1 is continuously expressed in the hypostome. During budding, hydra's asexual form of reproduction, the gene is expressed in a small area that will eventually form the hypostome of the developing bud before any morphological sign of budding is apparent. The gene is also expressed very
