Feeding habits of sardine (Sardinops sagax) in relation to their spawning activities
Feeding activity of sardine (Sardinops sagax) from St Helena Bay and Gans Bay in the Southern Benguela was studied between February and April 2011 and related to reproduction. Feeding intensity of 373 sardine was calculated and correlated with caudal length across different gonad maturity and fat …

Feeding habits of the yellowtail flounder and production of its invertebrate prey on Georges Bank
As part of the Georges Bank Benthic Infauna Monitoring Program, size-frequency analysis was used to study the life history and production of three benthic amphipod species: Ampelisca agassizi, Unciola inermis and Ericthonius fasciatus. Abundant over large areas of Georges Bank, these amphipods are …

Effects of the Physical Characteristics of Grain on the Life Cycle and Feeding Habits of Tribolium Castaneum
Much has been written about Tribolium spp. (Coleoptera: Tenebrionidae) both as an important pest of stored products and as an experimental animal in biological sciences. Yet there is still no consensus on some important aspects of the ecology of Tribolium in stored products ecosystems. Two of these …

A Comparison of Bioaccumulation and Digestive Enzyme Solubilization of Copper in Two Species of Sea Cucumbers with Different Feeding Habits.
<p>The mode of feeding exhibited by different organisms may influence the form or quantity of copper that is bioaccumulated. This hypothesis has been tested by exposing 2 species of sea cucumbers, <em>Pentacta anceps</em> and <em>Stichopus chloronotus</em>, which possess different feeding modes, to …

The impact of seasonally changing feeding habits on the secondary production and accumulation of mercury in a filter-feeding Caddisfly
Food habits, net-spinning activity, energetics, and mercury accumulation in Hydrospsyche morosa were examined over a one year period on the South River in central Virginia. Feeding nets were observed as early as April and were widespread by May. Nets were virtually absent from late November through …

Effects of illumination, shading and temperature on the settlement, survival and growth of juvenile abalone (Haliotis midae)
… there remains a lack information on the feeding habits of the early life stages and as a result the survival rates of spat are still low and variable. This prompted the design of three experiments to determine the best illuminance and water temperature conditions to maximize the …

Investigating the impacts of donkeys on a communal range in Namaqualand: how much does a donkey "cost" in goat units?
… was scored using dung frequency transects, and feeding was directly observed. It was found that in the wet season, one donkey eats as much as 5 / 7.6 goats (donkey weight set at 200 and 250 kg respectively). In the dry summer, this ratio increases to 7.6 / 8.6 because in ruminants, the passage …
