ABSTRACT Pointed, rod-shaped bacteria colonizing the cuticular surface of hindgut terrestrial isopod crustacean Porcellio scaber (Crustacea: Isopoda) were investigated by comparative 16S rRNA gene sequence analysis and electron microscopy. The results phylogenetic analysis, absence a cell wall, affiliated these with class Mollicutes , within which they represent novel deeply branched lineage, sharing less than 82.6% similarity to known . lineage has been positioned as sister group clade...
A novel spotted fever group Rickettsia was found in Haemaphysalis sulcata ticks collected from sheep and goats Croatia 2006. At the same time, a genetically identical organism co-isolated with embryonic cell line CCE3 obtained soft tick Carios capensis Georgia, USA. In this study, further phenotypic genotypic characteristics of rickettsial strain present H. were investigated. Based on cultivation bacteria mosquito Vero cultures, presence rickettsiae tissues cultures [confirmed by...
Assessing decapod sensitivity to regional-scale ocean acidification (OA) conditions is limited because of a fragmented understanding the thresholds at which they exhibit biological response. To address this need, we undertook three-step data synthesis: first, compiled dataset composed 27,000 datapoints from 55 studies responses OA. Second, used statistical threshold analyses identify OA using pH as proxy for 13 response pathways physiology behavior, growth, development and survival. Third,...
Intracellular bacteria were observed in the hepatopancreas of terrestrial isopod Porcellio scaber . Comparative 16S rRNA gene sequence analysis and electron microscopic observations used to determine taxonomic position these intracellular bacteria. Phylogenetic a complex developmental cycle affiliate order Chlamydiales , within which they form distinctive lineage, close family Simkaniaceae They share <92 % similarity with their closest relative <88 other members A specific signature...
To understand better the adaptation strategies of intra-annual radial growth in Pinus halepensis and sylvestris to local environmental conditions, we examined seasonal rhythm cambial activity cell differentiation at tissue cellular levels. Two contrasting sites differing temperature amount precipitation were selected for each species, one typical their other represented border climatic where two species coexisted. Mature P. trees from Mediterranean (Spain) sub-Mediterranean (Slovenia) sites,...
Coastal-estuarine habitats are rapidly changing due to global climate change, with impacts influenced by the variability of carbonate chemistry conditions. However, our understanding responses ecologically and economically important calcifiers pH temporal variation is limited, particularly respect shell-building processes. We investigated mechanisms driving biomineralogical physiological in juveniles introduced (Pacific; Crassostrea gigas) native (Olympia; Ostrea lurida) oysters under...
The distribution and orientation of microtubules were investigated in cells distinct shapes from different hindgut regions adult Porcellio scaber Latreille, 1804 during morphogenesis late embryonic early postembryonic development. All P. contain abundant apico-basal organized extensive bundles, but the architecture bundles is specific for cells. In anterior chamber microtubule closely coincides with this region are most prominent associated muscles. shape that form typhlosole channels...
The moult cycle of Porcellio scaber was studied in order to determine the typical shape sternal calcium deposits during premoult. Males and non-breeding females were observed for 13 weeks. According appearance, size, deposits, premoult divided into three substages which occurred all animals investigated. easiest least disturbing way stage isopods routine experiments is identify one substages. duration both sexes approximately 33 days, with greater variation females. proposed procedure...
Arthropods exhibit a vast variety of morphological forms. Developmental studies on diverse arthropod groups will help clarify how these forms evolved during evolution. The terrestrial isopod Porcellio scaber is suitable novel animal model for developmental studies; it well adapted to habitats and adaptations make the species interesting from evolutionary perspective. already extensively used in ecotoxicological physiological its biology known, but comprehensive description ontogenetic...
Specialized mechanical connection between exoskeleton and underlying muscles in arthropods is a complex network of interconnected matrix constituents, junctions associated cytoskeletal elements, which provides prominent attachment the epidermis to cuticle transmits muscle tensions exoskeleton. This linkage involves anchoring extracellular composing apical membrane tendon cells linking basally. The ultrastructural arhitecture these complexes during molting an important issue relation...
