An attempt is made, from Australian field experience and the experimental record, to identify the climatic factors important in tropical pasture legume seed production. The main properties of the crops (primarilyStylosanthes spp., Macroptilium atropurpureum, Desmodium spp. and Glycine wightii) taken into account are: their usual adaptation to a cycle of summer vegetative and winter reproductive development; their common short-day flowering response; their need for a reliable dry season to stimulate vigorous reproduction, reduce disease risk, and facilitate harvesting; and their susceptibility to frost. The more important general requirements for suitability of a region for seed production are seen to be that: its annual average rainfall should be 800-2000 mm, with a predominantly summer wet season and no more than 400 mm falling outside the four wettest months; the average daily mean temperature of the coolest month should not fall below 17C; the ground frost risk should be low; and the latitude should be greater than 10. These values are used to map Australia, India, South and Central America, and Mexico in terms of their potential for seed production. |

The gross morphology of foregut was investigated and described in detail for four freshwater crab species: a pseudothelphusid, Fredius reflexifrons (Ortmann, 1897) and three trichodactylids ? Sylviocarcinus pictus (H. Milne-Edwards, 1853), Valdivia serrata White, 1847, and Dilocarcinus septemdentatus (Herbst, 1783). In general, the gastric mills of freshwater crabs showed a similar degree of complexity in relation to other marine species of Anomura and Brachyura previously described in the literature. However, significant morphological differences were observed among the analyzed species, as in ossicle numbers, features and connection types. A total of 38 ossicles were described for S. pictus and V. serrata and 37 ossicles for D. septemdentatus and F. reflexifrons, respectively. The latter species can be distinguished from the others by the presence of a wide cardiac sac resembling two sacs. Most of the ossicles were connected through a rigid connection, and few ossicles were fused. The degree of calcification varied little among the studied species. The differences found among the species suggest that the morphological aspects of the foregut may be useful in the identification of similar species. |
