An experimental programme has been undertaken to determine which of the grain formation mechanisms equiaxed crystals are dominant in solidification Al–Si foundry alloys. Small ingots were cast from alloys varying silicon concentration with and without gauze barriers, using different types mould materials preheats. The results show that two nucleation operating. first is a wall mechanism where nucleated either on or near owing thermal undercooling. second constitutional supercooling nucleants...
Observations of 17 heifer-calf pairs were collected over the first 5 days postpartum (p.p.) to study nursing and maternal behaviour beef cattle. Cattle managed in a 6 ha paddock heifer–calf interactions determined from both regular visual observations video recordings. Of potential calves, one was stillborn 3 died p.p. associated with dystocia congenital malformation. Four further neonatal calf mortality risks identified, which included poor calving site selection (n = 1), misadventure...
A reliable method for the confirmation of sex in Geocrinia frogs is currently unavailable. captive colony was used to determine whether fecal steroid analysis could be as a noninvasive diagnosis mature frogs. Linear discriminate analysis, using measured concentrations hormones, also applied establish model developed verify juvenile Fecal samples were collected over 3-month period from all 2010, and again 12 2011. Samples pooled each individual tested testosterone metabolites (TMs) estrone...
The nocturnal nature of wombats makes it difficult to learn about their behavioural ecology and activity rhythms in the wild. A facility was established at Rockhampton Zoo house 12 adult southern hairy-nosed order monitor behaviour by means video surveillance provide detailed information on patterns using movement-sensitive radio-transmitters. After one year monitoring that spent, average, as a proportion total time 69.9% sleeping, 8.8% lying resting, 5.2% feeding, exploring, 4.3% performing...
The southern hairy-nosed wombat (Lasiorhinus latifrons) is under threat as its current distribution range and population size declining. low reproductive rates observed for this species, both in the wild within captivity, are a cause concern; such study was designed to provide comprehensive account of behaviour L. latifrons. four groups captive animals (each 1♂ : 2♀) remotely monitored 14 months using digital video-surveillance system. Using technology, 13 distinctive reproductive-based...
This study compared the efficacy of plastic glitter, with a mean particulate size 1.18 mm, as faecal marker in group-housed captive wombats Lasiorhinus latifrons. The voluntarily consumed glitter through use appetizing food vehicles. Over 40 different treats were tested possible vehicles for oral delivery and these six deemed highly palatable: (1) golden syrup horse pellets, (2) weetbix, (3) pitted dates, (4) honey kangaroo (5) nutrigel rolled-oats, (6) strawberry sauce rolled-oats. Mean...
The influence of scotoperiod, ambient temperature and humidity on the activity captive wombats was examined to differentiate environmental from that pertaining food availability. 12 (Lasiorhinus latifrons) housed at Rockhampton Zoo remotely monitored by digital video-surveillance for one year, with variables simultaneously recorded via dataloggers. Mean proportion total daily time spent active 18.2 ± 1.8%. varied seasonally according changes in humidity. greater during winter (301 17 min)...
Abstract This study examined the spatial defecation patterns of numbats within captivity and tested efficacy a food colorant as fecal marker in this species. Rather than randomly distributing scats throughout their environment, aggregated feces at specific sites forming latrines. It is unclear whether strong inclination for latrine formation was due to species' inherent behavior or direct result captivity. Males were found have higher daily rate, different time, larger number latrines,...
