Weeds are plant disturbing organism that affect yields through competition and allelopathy. However, not much is known about weed diversity in swamps, so research needed to identify their types compounds as a control strategy. This study was conducted using survey method from January March 2020 at the Barito Kuala District, South Kalimantan. Thirty villages were randomly selected each of eight ...

Artificial floating islands (AFIs) have been documented as an efficient, environmentally friendly, and cost-effective solution to address nutrient pollution. However, most AFI studies date conducted in controlled experiments, applications natural settings, particularly the U.S. Midwest, are limited. Here, we present results of a combination field mesocosm experiments with two native aquatic pla...

Th e pasting behavior of native Water Chestnut Starch – hydrocolloids mixtures was studied. Th e eff ect of Xanthan, Guar, Carboxy Methyl Cellulose and Acacia on Water Chestnut Starch was examined by using micro Viscoamylograph. It was noticed that all hydrocolloids greatly modify the pasting properties of water chestnut starch. Results showed that gelatinization temperature of water chestnut s...

ABSTRACT A three-generation American chestnut x Chinese chestnut pedigree was used to construct a genetic linkage map for chestnut and to investigate the control of resistance to Endothia parasitica (chestnut blight fungus). DNA genotypes for 241 polymorphic markers (eight isozymes, 17 restriction fragment length polymorphisms [RFLPs], and 216 random amplified polymorphic DNAs [RAPDs]) were ass...

Before European settlement, vast areas of the eastern US deciduous forest were dominated by oak species. Evidence indicates that periodic understory fire was an important ecological factor in the historical development of oak forests. During European settlement of the late 19th and early 20th century, much of the eastern United States was impacted by land-clearing, extensive timber harvesting, ...

Habitat loss and fragmentation have been identified as important factors in the decline of grassland bird populations. However, population declines are apparent even in prairie ecosystems that remain relatively intact suggesting that additional factors are involved. The degradation of breeding habitat may be one such factor, but few studies have examined habitatspecific demography of grassland ...

We describe the spatial aggregation of the magpie goose (Anseranas semipalmata) in relation to the dynamics of the ephemeral floodplains of northern Australia. Past broad-scale studies have linked geese to floodplains dominated by the sedge, Eleocharis dulcis, but the type of response has not been determined, nor the impact of predation on food plants. Moreover, departure thresholds are not kno...
