  • The Biology and Ecology of Samson Fish Seriola Hippos
    The biology of Samson Fish Seriola hippos with emphasis on the sportfishery in Western Australia. By Andrew Jay Rowland This thesis is presented for the degree of Doctor of Philosophy at Murdoch University 2009 DECLARATION I declare that the information contained in this thesis is the result of my own research unless otherwise cited. ……………………………………………………. Andrew Jay Rowland 2 Abstract This thesis had two overriding aims. The first was to describe the biology of Samson Fish Seriola hippos and therefore extend the knowledge and understanding of the genus Seriola. The second was to uses these data to develop strategies to better manage the fishery and, if appropriate, develop catch-and-release protocols for the S. hippos sportfishery. Trends exhibited by marginal increment analysis in the opaque zones of sectioned S. hippos otoliths, together with an otolith of a recaptured calcein injected fish, demonstrated that these opaque zones represent annual features. Thus, as with some other members of the genus, the number of opaque zones in sectioned otoliths of S. hippos are appropriate for determining age and growth parameters of this species. Seriola hippos displayed similar growth trajectories to other members of the genus. Early growth in S. hippos is rapid with this species reaching minimum legal length for retention (MML) of 600mm TL within the second year of life. After the first 5 years of life growth rates of each sex differ, with females growing faster and reaching a larger size at age than males. Thus, by 10, 15 and 20 years of age, the predicted fork lengths (and weights) for females were 1088 (17 kg), 1221 (24 kg) and 1311 mm (30 kg), respectively, compared with 1035 (15 kg), 1124 (19 kg) and 1167 mm (21 kg), respectively for males.

Richards * The Sandgroper, Cylindracheta spa., is usually pictured as a rather affectionate, harmless little character which has become an unofficial emblem of Western Australia. Its habit of spending its life burrowing and digging in the sandy soils of our coastal areas has been responsible for the name "sandgropers" to describe West Australians. However, in the Gingin, Dandaragin, Badgingarra and other coastal areas, sandgropers have damaged crops of barley, sweet lupins and wheat in the last few years, in some cases causing Adult sandgroper.

Miniature landscape comprises plastic/rubber animals, miniature helicopters and termite mounds. This five-metre hybrid helicopter reflects the story of Jandamarra or Pigeon, a young Bunuba hero who led the resistance against the invasion and pastoral occupation of Aboriginal lands in the Kimberley in the 1890s. Jandamarra was an exceptional marksman and his improvised manufacture of ammunition using found materials, as well as his ability to evade capture by the authorities earned him a reputation that has become legend. He was said to be able to fly like a bird and disappear like a ghost. The helicopter is also a visual reference to the importance of aerial mustering as part of the pastoral industry in which so many Bunaba people continue to be involved. Initially proposed as an experiment in collaborative art-making with mature age students at Karrayili Adult Education Centre, the project was developed by accomplished Filipino Australian artist and teacher Alwin Reamillo, with Roselin Eaton, an Walmajarri artist, student and arts worker.

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1).

By Margaret & Gerry Kerrigan On a very humid Thursday morning ten Sandgroper vans pulled into the Narrogin Caravan Park. All were greeted by the manager who showed us to our sites, helped where necessary with positioning of vans and presented each couple with a welcome $10 voucher with the compliments of the local Chamber of Commerce. These could be used in many of the shops and town businesses. All spent the remainder of the day chatting and catching up with news over cold drinks. It was a cooler Friday morning with a threatening sky, and we were off in shared vehicles to the Narrogin Agricultural College for a nine o’clock start Tour of the farm. Unfortunately, this was the only day available for the tour as schooling was happening at this time. We travelled in a school bus around the property with two of the students instructors giving us an account of what we were seeing and answering our many questions. First stop was the new shearing shed, then into the older shed where black faced Suffolk sheep were being prepared for the Wagin Woolarama next weekend. These were the first type of sheep brought from England by the early settlers before Merino sheep were introduced twenty years later.

Here we perform a test of the hypothesized trade off between the number and size of offspring using thousands of descriptions of the number of egg-producing compartments in the insect ovary (ovarioles), a common proxy for potential offspring number in insects. We find evidence of a negative relationship between egg size and ovariole number when accounting for adult body size. However in contrast to prior claims, we note that this relationship is not generalizable across all insect clades, and we highlight several factors that may have contributed to this size-number trade off being stated as a general rule in previous studies.
