SUMMARY Recent studies have shown that some digenean trematodes previously identified as single species due to the lack of distinguishing morphological characteristics actually consist of a number of genetically distinct cryptic species. We obtained mitochondrial 16S and nuclear ITS1 sequences for the redial stages of Acanthoparyphium sp. and Curtuteria australis collected from snails and whelk...

Cuscuta australis (C. australis) seed and stem are historically used by the local population as dietary supplement for the management of infertility. This study, therefore, evaluated the effect of orally administered aqueous extracts of C. australis seed and stem, 300 mg/kg body weight/day for seven days, on the testis of the adult Wistar rat fed either low or normal protein-energy diets. The c...

Invasive species pose one of the greatest threats to global biodiversity. Early detection invasive is critical in order prevent or manage their spread before they exceed ability land management groups control them. Optical remote sensing has been established as a useful technology for early and mapping vegetation populations. Through use airborne hyperspectral imagery (HSI), this study establis...

In gastropods, variation in shell morphology can be caused by the action of several biotic and abiotic factors. While much of this variation is seen in comparisons between different sites or populations, there is also substantial variation in shell morphology among individuals living side by side. We investigate the effect of trematode parasitism on both intraas well as inter-site variation in ...

Seaweed or sea macroalgae are rich in potential compounds which can be used for the treatment of disease. Padina australis is one important brown classes (Phaeophyes). One bioactive P. a phenolic compound and its derivatives (flavonoid). In this research, was collected from Bayah Beach, Banten, Indonesia. For extraction flavonoids australis, ultrasound-assisted (UAE) employed. study, three-leve...

Background: Cornus sanguinea L subsp australis (C.A. Mey.) Jáv. (Cornaceae) is a native species in north and northwest of Iran. It is locally named Siah-al. The genus Cornus is rich source of anthocyanins. Objective: In this study the antioxidant activity, total phenol and total anthocyanin contents of different extracts of C. sanguinea L subsp australis. were investigated for the first time. ...

The water stress tolerance of Phragmites australis (Cav.) Trin ex. Steud. grown in the laboratory were investigated by examining effects of different levels of imposed water deficits on growth, photosynthesis and various physiological traits related to water stress. Individual plants were grown under conditions of unrestricted water supply and compared with groups of plants receiving 60, 30, 15...

The South American fur seal reproductive histophysiology is scarcely described. This study provides a histological description of prepuberal South American fur seal (Arctocephalus australis) ovaries as well as three-dimensional reconstructions of subcapsular crypts and primordial follicles. Ovaries from fresh dead animals were processed for histology and sliced into serial sections. A portion o...
