New eastern Australian species in the wolf spider genus Artoriopsis (Araneae, Lycosidae, Artoriinae)
Artoriopsis Framenau, 2007 is an Australian wolf spider (Lycosidae Sundevall, 1833) genus in the subfamily Artoriinae 2007. One of its species, A. expolita (L. Koch, 1877), has recently been introduced to New Zealand. Five new species are described here, bogabilla sp. nov. (males only); lacustris (male only), orientalis and females)—all only known from South Wales—A. mulier (female only) Canber...
Abstract: Aim Investigating whether wild fish accept residual ration from cage farming to the point of changing their diet and fish-food interaction network. Methods The species, Astyanax lacustris, Iheringichthys labrosus, Leporinus amblyrhynchus, Schizodon nasutus Steindachnerina insculpta, bred in Chavantes Reservoir, Upper Paraná basin, was evaluated. Samples were collected on a monthly bas...
Despite the unprecedented development in identification and characterization of prophenoloxidase (proPO) in commercially important decapods, little is known about the evolutionary relationship, rate of amino acid replacement and differential selection pressures operating on proPO of different species of decapods. Here we report the evolutionary relationship among these nine decapod species base...
Biomonitoring, assumed to be an integrative measurement of the chemical exposure of aquatic organisms, is not straightforward for essential metals because they can be actively regulated by animals. Although increasing bioaccumulation with exposure levels is a crucial endpoint for the development of biomonitors, it is rarely verified in real environments, where the metal concentrations are rathe...
Large numbers of a distinctive trachymedusa were observed at 1967 m depth just above the bottom in Suruga Bay, Japan, during a dive by the crewed submersible Shinkai 2000 in April 2002. Two individuals were collected and proved to be an undescribed species, herein described as Voragonema tatsunoko sp. nov. This species is characterised by the number (9) and shape of the centripetal canals. An i...
BACKGROUND Recent studies suggest that increasing ocean acidification (OA) should have strong direct and indirect influences on marine invertebrates. While most theory and application for OA is based on relatively physically-stable oceanic ecological systems, less is known about the effects of acidification on nearshore and estuarine systems. Here, we investigated the structuring of a benthic i...
