In laboratory experiments, the ecological and assimilation efficiencies of the polychaete Nereis virens cultured on biodeposits of oysters (5.7 and 28.8%) were lower than for worms grown on clam tissue (18.0 and 77.3%). However, a high consumption rate of biodeposits resulted in a growth rate (48% increase in dry wt) higher than for worms fed clam tissue (31% increase). Mucus production by Nereis virens accounted for several percentage points in the calculation of efficiencies. Biodeposits in both natural and aqua-culture environments might be exploited as a food source for this species.

Lake Fish

This research was conducted to analyze the content of Fe, Cu, Cd, Cr, and Pb in several species of fish taken from three lakes that are close to the disposal of industrial waste in Indonesia. The fish samples were taken from three lakes, namely, Muara Angke, Weda, and Morowali. The samples from Morowali were analyzed in April 2019, those from Weda from November to December 2019, and those from Muara Angke in June 2018. All the samples were then analyzed at the Chemistry Laboratory of the Department of Chemistry, Faculty of Mathematics and Natural Science, University of Indonesia, and the Integrated Laboratory of IPB. The main results showed that all types of fish from Morowali and Weda were no longer safe to consume because they contained Fe, Cu, Cd, and Cr exceeding the threshold of metal contamination. Meanwhile, all types of fish from Muara Angke, except for ayam-ayam, are still safe for consumption. The results of this study can be a source of information regarding metal content in fish and fish feed for safe consumption. Given the high consumption rate of fish and the hazards of heavy metals on humans’ health, such research must be furthered.

High Consumption

Inappropriate packaging design and implementation of quality improvement of plastic waste paradigm affected low acceptance of waste for mechanical recycling. This research proposed material value conservation paradigm with design for recycling principles as key solution in avoiding its value degradation. Phenomenology and plastic quality measurement implemented as methodologies of research. Some evident in Indonesia verified the presence of the new paradigm in practice and followed with estimation of its prospective benefit. The new paradigm will generate broader impact and more benefit if adopted for other type of materials, especially for region with high density of people and high consumption rate of conserved products.

Results of an intensive 9-year census of the arboreal spider fauna in a fir–spruce forest in north-western New Brunswick and of a 3-year census in similar biotypes in other parts of the province are reported. A total of 129 species were collected, although only 14, mostly web-spinning species make up the bulk of the spider population. Spider density over the years is remarkably stable in any one biotype. Considerable variation in species composition occurs between biotypes, but the density of the total spider complex in each varies little.Field experiments with a web-spinning Dictynid and "planted" populations of second-instar budworm larvae show a high level of predation but the wide prey selectivity, population stability, and other traits of the arboreal spiders suggest that, despite their high consumption rate, these predators are unlikely to respond to sudden outbreaks of a particular food item. It is assumed, therefore, that spiders have little influence in moderating the periodic population explosions of the spruce budworm.

The present work was undertaken to study the trends in use of chemical pesticides and fertilizers for tomato cultivation in vicinity of Lucknow city, India; to gather information regarding knowledge among farmers related to use of biological fertilizers and pesticides; and the constraints faced by them during tomato cultivation through questionnaire based survey. The study revealed the high consumption rate of agrochemicals suggesting farmer's sole dependency on them to protect tomato crop from pests and diseases, and to enhance productivity. The knowledge pertaining to biofertilizers and biopesticides among farmers was negligible. Most of the farmers were either illiterate or having low education level which was the major cause for indiscriminate use of agrochemicals. The area under tomato cultivation was observed to be reduced due to land fragmentation, urbanization, biotic and abiotic stresses. Biotic factors like occurrence of fungal and viral diseases, pest infestation and abiotic factors like scarcity of water, fluctuation in temperature conditions were major reasons for productivity loses.

Consumption Control

Alcohol consumption is one of the causes of premature death from the main non­communicable diseases (NCD), such as cardiovascular diseases, malignancies, diabetes. In the countries of Northern Dimension Partnership in Public Health and Social Well­being (NDPHW) alcohol consumption calculated for pure ethanol per person per year ranges from low ~8 L to high ≥12 L. In NDPHW countries where the inhabitants consume alcohol in low amounts, the probability of premature death from NCD is lower than in the countries with high consumption. It was shown that the events on alcohol approachability restriction were stricter in the countries with low consumption rate and hence with lower probability of premature NCD death. All NDPHW countries, except Germany and Estonia, are in the 20 of the countries with the highest score according to the politics of alcohol control that witness on effective implementation of the events for consumption control. Therefore acception and implementation of strict politics may facilitate the decrease of alcohol consumption and then, the rate of NCD premature death.
