this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
the study aims to achieve research and testing of hypotheses survey techniques and questionnaires to collect information used. 61 questions in the questionnaire included 15 questions and 46 open questions according to research in the study population, girls and their mothers as the value of different children investment should be. mothers according to the research community benefits from havi...
The functional groups and the ecological health of a constructed oyster reef were investigated during April 2016 to October 2017 in Yangtze estuary. data long-term monitoring program (14 years) confirmed feasibility creating an artificial One or two absent from moderate salinity conditions (5.17% - 8.73%), while macrobenthos group species richness, abundance, biomass greatest under high conditi...
Plants ecosystems are a habitat for a wide variety of species, some occurring in high densities and provide food and shelter for a large number of commercially valuable finfish and shellfishes. They are productive habitats and support coastal fisheries [1]. The mangrove forests are extremely important coastal resources, which are vital for socioeconomic development of the region. As a detritus-...
The paper deals with the standing stock of macrobenthic infauna and associated environmental factors influencing the benthic community in the shelf region of the northwest Indian coast. The data were collected onboard FORV Sagar Sampada during the winter monsoon (January-February, 2003) to understand the community structure and the factors influencing the benthic distribution. The environmental...
A multimetric benthic assessment method was developed for two benthic assemblages in the San Francisco Estuary (USA) using data from several monitoring programs collected over five years. Assessment indicators used were total number of taxa, total abundances, oligochaete abundances, number of molluscan taxa, number of amphipod taxa, and Capitella capitata and Streblospio benedicti abundances. E...
Assessing the short-term stability of spatial patterns of macrobenthos in a dynamic estuarine system
Recent studies of macrofauna on sandflats have emphasized postsettlement dispersal, particularly associated with sediment bedload transport. This study investigated the short-term (3 weeks) stability in spatial patterns of eight common, potentially mobile, near-surface macrofaunal species inhabiting a 4,000-m2 area of intertidal sandflat. Over this period, wind conditions reworked the sediment ...
The present investigation focuses on the Global Sea Mineral Resources contract area B4S03 site in Clarion-Clipperton Fracture Zone nodule fields. We investigated sedimentary characteristics and higher-taxon (order/class) lower-taxon (family, morphospecies) diversity of soft sediment macrobenthos with special focus dominant taxa (Isopoda, Polychaeta, Tanaidacea) relation to abundance. Across all...
