| Abstract | Seasonal forest ponds (SFPs) are isolated, ephemeral lentic habitats in upland forest ecosystems. These ponds occur commonly throughout temperate forests. Faunal communities of these ponds are dominated by invertebrates. Composition of these communities varies temporally both between years and also seasonally within a single hydrologic year, composition is most affected by pond permanence or hydroperiod. Benthic macroinvertebrates (BMIs) were sampled up to three times a year in five SFPs between 1994 and 1996. The ponds were of short, intermediate, and long hydroperiod. Hydroperiod also varied among years, based on precipitation patterns. During the study, 64,000 specimens of 57 taxa were collected. No pattern was identified in the variation of BMI abundance among years and pond hydroperiod; abundance increased with successive surveys within years. Taxon richness and diversity varied significantly with pond hydroperiod, increasing with increasing hydroperiod. Diversity measures increased over the three years of the study but without obvious pattern across the successive surveys within years. Insects dominated the samples, but large numbers of other Arthropoda and Oligochaeta were also collected. Chironomidae were dominant in most ponds, years, and surveys; chironomid dominance was significantly greater in shorter hydroperiod ponds. Seasonal forest ponds function as aquatic islands in a “sea” of terrestrial forest. The effect of hydroperiod on the composition of the benthic macroinvertebrate community is analogous to that of size on marine island fauna, longer hydroperiod ponds generally have richer invertebrate communities just as larger marine islands typically have richer faunas. However, the effect is confounded by the close relationship between pond hydroperiod and pond size/volume. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
