...L. Llewellyn Length - weight relationships for 29 fish species occurring in the Murray-Darling River System in inland NSW were determined using data collected principally between 1957 and 1970. In Golden Perch Macquaria ambigua , this relationship is examined with regard to locality, year and sex...

...Allen Greer; Sarah Smith In the small Australian dragon (agamid) lizard Tympanocryptis tetraporophora mean snout-vent length (SVL) does not differ significantly between the sexes within the species as a whole. However, in a large sample from Sturt National Park, in northwestern New South Wales...

...Andrew Stauber; David David Allometry in size and shape between sexes was investigated in preserved Bearded Dragon Pogona barbata museum specimens. Measurements for snout-vent, head, leg and tail lengths were obtained from 236 individuals ranging from hatchlings to large adults. Juveniles...

... by 2.03 - 3.78mm, and were attached in a cluster to solid objects. Their oil globules were small and numerous. The eggs hatched 3 – 8d after fertilisation, at temperatures of 20.2 - 29.0oC. The length of larvae at hatching varied from 3.44 - 4.15mm. The prolarval stage terminated approximately 61?2d after...

... ° South. Forty seven V. vulturnus (24 females and 23 males) were captured in harp traps set in five different vegetation formations. Bats were captured in riverine woodland near water and in woodland to open forest habitats well away horn water. The mean forearm length of 19 males (24.7 mm...

... there is limited information on the extent of carcass use by scavengers and the length of carcass persistence. This prevents land managers from making well-informed decisions on whether carcasses should be removed if produced in excessive numbers following activities such as culling, or extreme weather and disease...

... Perch Macquaria ambigua . Monthly frequency of recapture appeared to follow angling pressure. The length/ weight relationship curves of recaptured fish at tagging and recapture are similar (y=1.49E-06x 3393 and y= 7.32E-06x 31374 respectively), supporting the use of the data for growth analysis. Von...

... demersal, transparent, spherical, telolecithal and slightly adhesive; possessed a cluster of oil globules; varied from 1.35mm to 1.66mm in diameter; and appeared to be scattered randomly on the pond bottom during spawning. Eggs hatched after 8½ to 9½ days. The length of recently-hatched larvae ranged from...

... length. Females had smaller fat bodies more frequently than did males. Amplexus was axillary. Females contained horn at least 512 to 3054 eggs. and averaged 1868.3 eggs in unambiguously complete clutches. There was no relationship between either clutch size or weight, and female snout-vent length...

... and the breeding display was recorded. Eggs were demersal, transparent, telolecithal and an elongated tear-drop shape with an adhesive disc at the pointed end. They measured 1.2 - 2.2 mm in length by 0.7 - 0.9 mm in width, and were attached in clusters to solid objects. Oil globules were small and numerous...

... Red-tailed Black Cockatoos may be estimated by comparison with photographs taken of nestlings of known age or estimated more precisely from the length of the nestling's folded wing. Aging nestlings enables the calculation of laying and hatching dates. breeding ecology aging nestlings relationship...

... in postflexion larvae. Pigmentation is relatively heavy and uniform over the head and body. Large melanophores occur on the dorsal, lateral and ventral midlines. Squamation commenced in postflexion larvae from 7.5 mm preserved body length (BL) and was complete in all specimens greater than 10.3 mm. Live captive...

... be a contributing factor to this decline, morphometric data was gathered for southern bent-winged bats and compared with the more common eastern bent-winged bats. Southern bent-winged bats were heavier, but forearm length was not significantly different between the two subspecies. This suggests that southern bent...

... nestlings than young females. Despite the length of the study, few data are available on longevity in the species, other than one known age female breeding in her 27th year, and one female of unknown age breeding when she was at least 30 years old. Nestling body mass is a useful indicator of population...

... is influenced by nest box size, shape and entrance dimensions. In this study the temperature and humidity patterns were recorded within six nest box designs that were exposed to direct sunshine. All were constructed of 19 mm plywood but varied in length by a factor of 2X, in volume by 3.5X and in entrance areas...

... in abundance across habitat type for these families, excluding Dasyuridae, but including Gekkonidae. We conclude that having a central bucket where drift fences join can increase trap success, and this is a function of effective trapping area (i.e. catchment of animal activity and length of drift fence per...

... to have endocrine disruption effects on G. holbrooki had lower density and biomass of fish than other wetlands. In contrast, the pattern of variation in the average length and phenotypic sex ratio of fish was not consistent with the effects of endocrine disruption. endocrine disruption...

... and mature dugongs contained detectable levels of oestradiol and testosterone. Faecal testosterone levels were high relative to oestradiol concentrations in all samples, regardless of gender. The highest levels of testosterone occurred in adults (body lengths ≥250 cm), in both males (1146.7 ng g -1 dry...

... trapping period. Information collected on the body mass, body length and condition of individuals indicated smaller individuals with a higher tail fat index in the lower order streams. There was a trend toward a lower occurrence of platypuses in the first order streams, which had been disturbed 15 years...
