The genus Stantonia Ashmead, 1904 (Hymenoptera, Braconidae, Orgilinae) is reviewed for Vietnam, China, Japan, and Russia. Six new species of the genus Stantonia are described and illustrated: Stantonia brevicaudata van Achterberg, sp. n., S. dickyyui van Achterberg & Long, sp. n., S. granulata Long & van Achterberg, sp. n., S. robustifemur van Achterberg & Long, sp. n., S. stilpnosoma Long & va...

The seasonal dynamics of cyanobacterial and diatom assemblages in 11 water bodies along a mesoto hypertrophic gradient were compared. The cyanobacterial and diatom communities are characterised according to representative species of each algal class, selected by data reduction following principal component analyses and discriminant analysis. The cyanobacterial and diatom assemblages of the four...

Two new species of oribatid mites of the genus Lasiobelba (Oribatida, Oppiidae), Lasiobelba (Lasiobelba) daamsae sp. n. and Lasiobelba (Antennoppia) nepalica sp. n., are described from eastern Nepal. Lasiobelba (L.) daamsae sp. n. is most similar to L. (L.) remota Aoki, 1959 and L. (L.) gibbosa (Mahunka, 1985), however, it differs from both by the anterior part of pedotecta I specifically curve...

The materials of this study were collected from intertidal and shallow subtidal habitats of the Hengam Island coasts from May 2013 to May 2014. A total of 10 species representing eight genera and four families are reported as follows: Sphaeromopsis persikolpos Khalaji-Pirbalouty and Wägele 2009, S. sarii Khalaji-Pirbalouty and Wägele 2009, Sphaeroma khalijfarsi Khalaji-Pirbalouty and ...

Detailed cytological changes that accompany the rejuvenation of resting cells o/'Melosira granulata were studied with the electron microscope. Dormant and viable cells that we previously classified as the condensed state generally contain definable chloroplasts, mitochondria, a nucleus and other cytoplasmic remnants. However, there appears to be a continuous cytoplasmic degradation spectrum and...

The grapsid crab Chasmagnathus granulata populates brackish-water lagoons and other estuarine environments. In its reproduction, this species follows a strategy of larval export, i.e. its larvae live under different salinity conditions from the juveniles and adults. In the present experimental investigation, ontogenetic changes in the capability for osmoregulation were studied in all 4 zoeal st...
