The Value Of Oil Mallee Plantations And Revegetated Farm Land In The Southern Wheatbelt Region Of Western Australia For The Conservation Of The Western Pygmy Possum (Cercartetus Concinnus), Marie Short

Theses : Honours

Revegetation has the potential to enhance conservation of wildlife in rural environments, but few studies have tested whether the proposed benefits are realized. It is important to understand the role played by farm tree plantations in the landscape and how the potential biodiversity benefits may be enhanced without interfering with economic goals (Lamb, 1998). The adoption of oil mallee farming systems across the agricultural zone in south-west Western Australia is resulting in large areas of farmland being planted to native perennial tree species (Smith, 2004). While not planted for their conservation benefit, oil mallee systems may nonetheless enhance biodiversity. The …

Zoometrical Body Measurements And Their Relation With Liveweight In Native Turkish Geese, Mustafa Saatci, Muammer Ti̇lki̇

Turkish Journal of Veterinary & Animal Sciences

The aims of this study were to determine the body measurements of native Turkish geese and to define the relationship between these measurements and liveweight. The differences in head diameter and neck length between the sexes became significant at 10, 12, 14 and 16 weeks of age (P < 0.05-0.01). The beak and wing lengths increased with age and were longer in males than in females at 12, 14 and 16 weeks of age. The effect of sex on body and trunk length was significant at 14 and 16 weeks (P < 0.05-0.01). Chest depth, girth and width increased with age. The positive correlations (0.88-0.97) of liveweight with head diameter, neck length, body length, trunk length, chest girth, wing length and metatarsus length at 2 weeks of age were highly significant. The most reliable prediction from the regression analyses was between liveweight and body length + chest girth in weeks 2 and 8 (R^2 = 94%). Our study presents the body measurements and the correlations between these measurements and liveweight in geese of different ages. These correlations might be used to evaluate the liveweight of studied geese population and for selection based on liveweight.

Turkish Journal of Veterinary & Animal Sciences

The acute toxicity of carbaryl, methiocarb and carbosulfan to juvenile rainbow trout (Oncorhynchus mykiss; 1.92 ± 0.5 g) and guppies (Poecilia reticulata; 0.45 ± 0.04 g) was evaluated in 96-h toxicity tests under static conditions. Concentrations in the toxicity test ranged from 0.85 to 8.5 mg/l for carbaryl, from 0.7 to 28.0 mg/l for methiocarb, and from 0.031 to 12.5 mg/l for carbosulfan. Carbaryl and methiocarb were more toxic to rainbow trout than to guppies. However, compared with rainbow trout, guppies were more sensitive to carbosulfan. The incidence of mortality in fish increased significantly (P < 0.05) with increasing pesticide concentrations. The time required to kill 50% (LT_{50}) of the rainbow trout at the lowest concentrations of carbaryl, methiocarb, and carbosulfan was 51 h 12 min, 74 h 35 min, and 107 h 57 min, respectively. As insecticide concentrations were increased, LT_{50} values decreased (P < 0.05).
