In the maturing egg of Dryopteris filix-mas the nucleus is shown to produce sheet-like extensions into the cytoplasm, resembling those described in certain somatic cells of animals. In these sheets the distance between the 2 inner membranes of the envelope is regularly of the order of 45-50 nm, and the nuclear material is organized into a monolayer of electron-opaque aggregates 35-40 nm in diam...

We describe obstructions to a direct limit preserving right exact functor between categories of quasi-coherent sheaves on schemes being isomorphic to tensoring with a bimodule. When the domain scheme is affine, all obstructions vanish and we recover the Eilenberg-Watts Theorem. We use our description of these obstructions to prove that if a direct limit preserving right exact functor F from a s...

Alima pacifica and A. orientalis are stomatopods commonly found at Lizard Island, Great Barrier Reef, Australia. There are currently no descriptions that link the larvae to the adult morphotype despite the frequent occurrence of the last larval stage of these two species. We used DNA barcoding of the cytochrome oxidase I (COI) gene to link the last stage larvae of A. pacifica and A. orientalis ...

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...
