A census of Mysidae yielded a total twelve species plus two non-nominotypical subspecies found so far in fresh and oligohaline waters the Mediterranean, all belonging to subfamily Mysinae. Among nine fresh-waters, three are stenoendemics, namely single lake (Diamysis lacustris), neighbouring river systems (Paramysis kosswigi) or karstic cave (Troglomysis vjetrenicensis). Four species—T. vjetrenicensis, D. lacustris, fluviatilis, Paramysis adriatica sp. nov. described this paper—are confined...

Study material new samples marine waters Curaçao led detection five species. Four these have a and are here described as P. pricei sp. nov., laminata brattegardi ornata nov. One non-dimorphic is nuda Two groups...

Three species of Lophogastrida and eight Mysida are documented for samples from 5161–5497 m bottom depth in the Angola Basin. Previously known latitudinal ranges extended southward five species, bathymetric beyond 5000 six species. Upon revision subfamily Petalophthalminae (Mysidae), four previously attributed to genus Petalophthalmus integrated into Ipirophthalmus gen. nov. as I. liui et comb. nov., caribbeanus oculatus macrops mainly based on structure eyes presence setae telson. cristatus...

Objective. Heavy metals are potentially toxic substances, especially for the susceptible infant. Exposure to mercury (Hg) and lead (Pb) may result in neurotoxic nephrotoxic impairment anemia. Previous data on breast milk Pb Hg contents sparse or missing Austrian population. No evaluations of influence mothers’ lifestyles levels available. Methods. Five- 10-mL individual samples were provided from healthy mothers Vienna (urban; n = 59), Linz (industrial; 47), Tulln (rural; 59). A...

Four new species of the subgenus Heteromysis (Olivemysis) were detected in material from (sub)-tropical aquaria six public aquarium institutions around globe. Modifications pleopods by spines represent strongest structural complex used for differentiation within this subgenus: male 1–4 modified H. smithsoniana sp. nov., 2–4 plus female pleopod 2 hornimani nov. and waikikensis Additional important diagnostic characters are provided antennulae, uropods, telson. The sixi represents a very rare...

Three new species of the genus Heteromysis S.I. Smith, 1873 (tribus Heteromysini), are described from a rich stock mysids obtained on request international community professional aquarium keepers. The 18S rDNA and COI sequences three were distinct each other also published in DNA databases. (Olivemysis) schoenbrunnensis sp. nov. is morphologically characterized within subgenus Olivemysis based structure first second antennae, male pleopods, uropods, telson. (Heteromysis) gulfarii outstanding...

ABSTRACT The mysid crustacean Hemimysis anomala (‘bloody‐red shrimp’) is one of the most recent participants in invasion European inland waters by Ponto‐Caspian species. Recently species also became established England and Laurentian Great Lakes North America. Using information from mitochondrial cytochrome oxidase I (COI) gene sequences, we traced pathways H. ; inferences were enabled observed phylogeographical subdivision among source area populations estuaries basin. data distinguish two...

The order Mysida (2 families, 178 genera, 1132 species) contains species across a broad range of habitats, such as subterranean, fresh, brackish, coastal, and surface to deep-sea habitats. Stygiomysida 2 16 species), however, are found primarily in subterranean waters, but always waters with marine influence. body is divided into three main regions: cephalon, thorax, abdomen. They shrimp-like appearance, containing morphological features earlier referred defining "caridoid facies"....

Abstract. Growth of Posidonia oceanica (L.) DELILE was studied in a natural stand 4 m depth at Ischia (Gulf Naples). Renewal and growth leaves continuous throughout the year but showed strong seasonal modulation. The major factor for individual leaf as well aspects entire foliage is modulation appearance rather than growth. Leaf area index varied between 2 nm ‐2 autumn 6 late summer. Annual production estimated to be 613 g dw blades, 54 sheaths, 27 rhizomes. Rhizome highly different primary...

Continued massive invasion of Mysidae in the Rhine and Danube river systems, with first records order Mysidacea (Crustacea: Malacostraca: Peracarida) for Switzerland.-Asurvey invasive species belonging to Rivers adjacent freshwater systems revealed that certain have invaded waters many more countries than previously known.First Hemimysis anomala G. O. Sars, 1907 are given Switzerland, Slovakia, Hungary, Croatia Serbia.The same holds true Katamysis warpachowskyi 1893 Serbia, Limnomysis...

Twenty-one species of Mysidae were sampled by three ANDEEP expeditions to the Southern Ocean with epibenthic sledges dragged over deep-sea floor in realm 58–71° S and 00–65° W, depth 774–5190 m. Previously known ranges are significantly extended southward for four greater same plus two other species.

The mysids Siriella sp., Anchialina lobata, Heteromysis domusmaris and H. kaufersteinae sp. nov. were extracted from sponges sampled in shallow water at the coast of Lizard Island. range A. lobata is extended ≥5400 km along waterways SW-Australia to Coral Sea off NE-Australia. first recorded nature; this species was previously known only coral reef aquaria. differs closely related subgenus Olivemysis by basal segment antennular trunk being furnished with a mid-dorsal lobe bearing blade-like...

We studied the mineral composition of statoliths in 154 species belonging to 55 genera Mysidae. Fluorite (CaF2) was found 86% Recent species, vaterite (CaCO3) 9%, and no crystalline component 5%. Seven samples fossil from Upper Miocene deposits were exclusively calcite (CaCO3).Vaterite has peak occurrence fresh water, fluorite photic zone marine waters, organic oceanic deep waters. With respect population numbers different aquatic biota, prevails freshwater is dominant among all brackish...

Abstract Statoliths of 61 Recent species representing all subfamilies Mysidae were studied with special emphasis on internal structure. In addition 5 samples fossil statoliths from Miocene deposits examined. Species Boreomysinae and Rhopalophthalminae show simple roughly spherical organic statoliths, setae originating the sensory cushion anchored in statolith distal branches extending shortly below surface. All other possess mineralized greater structural complexity, differentiation core...
