An investigation of the growth and feeding responses of oligotrich ciliates to food types and concentrations : an approach to assessing the potential of marine planktonic ciliate blooms
… be important in the transfer of carbon through food webs. This study examined the impact of clonal ciliate populations on short term algal blooms. Numerical and functional responses (growth and grazing rates with varied food concentration)were established for 5 marine planktonic ciliates and …

Resource Partitioning in Seven Species of Sympatric Intertidal Chitons (Mollusca: Polyplacophora)
… and location/exposure on the rock surface), and food {gut contents) were partitioned among 7 species of sympatric intertidal chitons: Mopaliidae - Mopalia hindsii, M. ciliata, ~· lignosa, M. muscosa, and Katharina tunicata; and Ischnochitonidae - Tonicella lineata and Cyanoplax dentiens. Species …

The Use of Fallback Foods in a Population of Black Handed Spider Monkeys at Runaway Creek Nature Reserve, Belize
Seasonal fluctuations in preferred food availability cause some non-human primate species to occasionally rely on less-preferred food types, called fallback foods. Periodic reliance on fallback foods has led, in some cases, to the evolution of morphological traits geared towards their exploitation. …

Dairy-Met: compositional metagenomic analysis of milk and cheeses
… microorganisms play important roles in dairy foods and can, for example, contribute to the development of flavours and aromas, determine safety, cause spoilage or enhance the health of the consumer. It is thus important to understand thoroughly the microorganisms present in these food types. …

The Comparative Ecology of the Brown Hyaena (Hyaena brunnea) in Makgadikgadi National Park and a Neighbouring Community Cattle Area in Botswana
… livestock carcasses were the most important food source and other less important food types were fed on as they became seasonally available. In the Makgadikgadi National Park zebra was the most important food source although several other food types were seasonally important. In the …

Food preferences and demand in the brushtail possum (Trichosurus vulpecula)
… in the wild. The relative preference between food types found in the wild, however, has not been investigated in a controlled laboratory study. In this series of experiments, single and paired preference assessments and demand procedures were conducted systematically under laboratory …

Carcass Feeding for Captive Vultures: Testing Assumptions about Zoos and Effects on Birds and Visitors
… that feed from large carcasses in nature, this food type also has the potential to be beneficial to their welfare. In intelligent and usually inquisitive scavengers like vultures, a lack of activity and behavioral opportunities could be a welfare problem in captivity; providing them with a more …

Phobic finches: Investigating neophobia reactions in a colour polymorphic specialist, the Gouldian finch, Erythrura gouldiae.
… thesis examines the neophobic responses of a food and habitat specialist, the Gouldian finch, Erythrura gouldiae, within captive conditions across two experimental trial conditions. Dietary wariness was investigated to determine how this food specialist will respond to the novel appearance of …

Comparative evaluation of the AES-Chemunex lab blender Smasher®, Seward Stomacher®, Interscience Bagmixer® and Pulsifier® on viable cell counts of foods, noise level, ergonomics, and ease of cleaning
Proper microbiological examination of foods involves proper sample preparation in terms of mixing the solid or liquid food with a suitable sterile diluent (usually a 1:10 dilution) in a sterile bag and homogenizing them manually or by means of an instrument. This thesis addresses the effectiveness …

Smallholder agriculture and household food and nutrition security: a study from East Hararghe, Ethiopia
… production was mainly focused on staple food crops such as sorghum and maize, and a limited range of cash crops and animal products for sale. Nutritionally important food types such as vegetables, fruits, beans, eggs and meat were produced only by a minority of households and were largely …

Correlates of soy food consumption in Adventist Health Study-2

Formation and transport of undesirable compounds during repeated deep frying
… desirable flavors, colors and textures in food; yet, it also results in development of undesirable compounds especially when oil is repeatedly reutilized. Once these reutilized oils reach a stage where they show visible signs of deterioration due to repeat frying cycles, they can be …

Benthic assemblage development and larval ecology of marine invertebrates at Adelaide Island, Antarctica
… seasonality of occurrence. Diversity of larval types was comparable with data from other Antarctic and temperate studies but abundances were higher than in a similar study at Signy Island (60043' S, 45° 36' W). The range of larval types, durations, and times of spawning argues against any strong …

Seabird digestive physiology in relation to foraging ecology
… experimentally. Gut passage rates of different food types of tested in vitro digestibility may reflect dietary specialization, with favoured prey types excreted more rapidly than less frequently encountered prey. Mean retention times of solid digesta are significantly correlated with foraging …

Taxonomic, biological, population dynamics and behavioural studies on sod webworms (Lepidoptera : pyralidae: crambinae and scopariinae) of some Waikato (New Zealand) hill country pastures
… sabulosella is investigated. Studies are made on food types, larval growth rates and adult reproductive maturity. Longevity of adults, mating frequencies and female fecundity (taken as the number of eggs found in dissected field collected females) are measured. Egg fertility and viability as well …

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 …
