a field survey was conducted in wukari, taraba state to assess the diversity and abundance of insect species in selected habitats (residential, open field made up of grassland and an agroecosystem). sampling were done biweekly using light, pitfall and yellow pan traps set in 3 replicates, 30 m apart. insects recovered were wet preserved in 70% ethanol except butterflies and moths. representativ...
Response of Trophic Groups of Macrobenthic Fauna to Environmental Disturbance Caused by Fish Farming
Sediment dynamics and the hydrodynamics of the environment cause the complexity and variability in animal-sediment relationship, both in spatial and temporal. This study is focused on the response of macrobenthic fauna to environmental disturbance caused by fish farming using their trophic structure. Their changes in trophic structure can be used as an indicator of disturbance. Eight control si...
in order to investigate diversity of weed species in wheat fields in eastern parts of mashhad, an investigation was made in the year 2009. wheat fields was classified based on the acreage from 3-5 ha, 5-10 ha and higher than 10 ha. sampling was made randomly by a quadrate 0.5×0.5 in 9 fields of each group from jointing to heading of wheat in tow separate stages. type and total number of weeds w...

The purpose this study was to determine composition diversity riparian vegetation. research area consisted three types, namely teak plantations (A Station), mixed forest (B proce...
Moth species were studied from some selected districts of Assam (i.e., Cachar and Barpeta district) to determine their diversity index, species richness and evenness of Arctiidae and Geometriidae family of the moth fauna.The moths were collected by applying specialized trapping methods using UV light operating during night. Collected moth species were identified up to family-genusspecies level....
honeybee is a pollinator that has prominent role in agriculture products and nourishment for human. so, the most number of studies like genetic improvement were done on honeybee. recent advances in knowledge of molecular genetics of bee emphasize the potential for using genetic markers to select favored traits. this research was done to determine polymorphism of loci of first foraging age (aff)...
A study was carried out to investigate correlation between presence of specific microalgal species and Leptoconops biting midge larvae in its breeding habitats. Sand samples containing microalgae were collected from the beach where the midges were most commonly biting and from sand beaches which are potential as breeding habitats of Leptoconops. The survey covered sand beaches from 12 seperate ...
