Protospirura munimuniensis n. sp. from C. lamia was differentiated by having two denticles on each pseudolabium, males with the right spicule longer and more robust than the left, a V-shaped gubernaculum and six pairs of post cloacal papillae.

This research developed improved microscopic assessment criteria for the prawn, Penaeus (Melicertus) latisulcatus, by reviewing microscopic criteria used in the literature and assessing cell composition of ovary tissue from 97 females. Whilst histological staging is not a new technique, this research outlines new development criteria for assessing ovary development stages in P. latisulcatus. A principal component analysis (PCA) was used with the microscopic classification system and showed distinct groups for each stage. Based on the proportion of cell types, distinct groupings were apparent, which corresponded to the main microscopic stages, in particular for stage 3 ovaries. This revised classification will improve the accuracy of ovarian staging techniques for P. latisulcatus and can be used as a guide for the interpretation and analysis of macroscopic stages during seasonal spawning events for the purpose of better informing fisheries management.","PeriodicalId":49425,"journal":{"name":"Transactions of the Royal Society of South Australia","volume":"7 1","pages":"77 - 89"},"PeriodicalIF":0.8,"publicationDate":"2021-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87319954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For parasites that live within the host, part of the reason for this lack of information is that the hosts must be killed and dissected to determine which endoparasites they harbour, which has legal and/or ethical implications and limitations. These obstacles can be overcome by collecting and examining potential hosts that are found dead on roads or that are sacrificed as part of other non-related studies. In this study, our objective was to expand on our understanding of the gastrointestinal parasites of some common reptiles from an area in the vicinity of a study site in the Mid North region of South Australia by making use of snakes and large lizards that were found dead on roads or that were humanely killed for another study.

One of these trees is known, with the westernmost having not been seen again until it was thought to have been found in 2005 when a search party found a tree with a partially healed scar. Wells was an accomplished surveyor and followed the common practice of the times by recording relatively precise latitude readings, but not longitude. While the route the main party took is well documented and well known, this second traverse is unknown. To recreate the route Wells took and provide some probability as to the location of this tree, a more novel approach was required. Specialist spatial software was developed for this study that compares the elevations and distances between sand ridges meticulously recorded by Wells, enabling recreation of his traverse, providing some certainty as to the location of this remote tree.","PeriodicalId":49425,"journal":{"name":"Transactions of the Royal Society of South Australia","volume":"32 1","pages":"112 - 124"},"PeriodicalIF":0.8,"publicationDate":"2021-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77118180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regular monitoring of selected water chemistry and fish population characteristics has been conducted since 2018 by a “Friends of Parks” group in an ongoing project contributing to the conservation management for this endangered species. Mogurnda clivicola were abundant and healthy in Weetootla and Nepouie springs, with six or fewer fish displaying any skin lesions on each of the four sampling occasions of May and August 2019 and June and August 2020. Hence the fish populations were not adversely affected by the exceptionally low rainfall years of 2018 and 2019. Fish of less than 2 cm total length were present at each sampling time point, indicating that breeding can occur on an opportunistic basis rather than during a breeding season. Following a substantial flood during February 2020, a substantial breeding event resulted in large numbers of small fish and at Nepouie Spring.

Understanding the phenotypic plasticity of plant species that protect and/or store their below-ground biomass during floods may help to promote them if problematic, overabundant species – like Phragmites australis and Typha domingensis – are less plastic. To investigate mechanisms underlying the plasticity of two cosmopolitan (Phragmites, Typha) and two endemic (Cycnogeton procerum, Cyperus gymnocaulos) macrophytes in response to disturbance (fluctuating hydrological regimes) across a nutrient gradient, we analysed historical data from pond experiments with single-species pots. Our analyses showed fluctuating water levels in nutrient-enriched conditions reduced total biomass in all species, with 65% and 46% reduction in Phragmites and Typha respectively. Contrary to expectations, only Cycnogeton allocated a higher proportion of biomass to protect (root) and store (rhizome) resources in fluctuating water levels and nutrient-enriched conditions (45% versus 23% in stable regime), and was the most plastic by allocating 75% more biomass to belowground in the least favourable conditions. Our results indicate that removing impediments to stochastic flooding disturbance could benefit some endemic species while reducing the productivity of overabundant Phragmites and Typha in environments enriched by human activity.","PeriodicalId":49425,"journal":{"name":"Transactions of the Royal Society of South Australia","volume":"9 1","pages":"25 - 44"},"PeriodicalIF":0.8,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77684285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
