Gillette (3) described this species as Chermes similis in 1907. His description was of winged females from galls but he mentioned that wingless females and their egg clusters were also present in some galls, although there was no way to make certain that they were of the same species. The galls were on blue spruce from Colorado, and winged adults from these settled on spruce in cages. Patch (4) reported this species in 1909, on Norway, white, red, and black spruces from Maine. She found that the winged females settled 'on all these spruces but preferred white spruce. Wingless females with egg clusters were present in the galls and she assumed they were Chermes similis Gillette. Annand (1) placed the species in the genus Pineus, along with all species having four abdominal spiracles. He referred to the previous writers, and gave a description of a wingless adult, “probably from a gall”, included with Gillette's type material. He tentatively called this form a fundatrix. He also described a wingless female and a ‘nymph’ which Patch had found associated with galls of P. similis, as Pineus sp.

Biochemical Analyses

Controlled pollinations were made within and between blue spruce (Picea pungens Engelm.) and white spruce (Picea glauca (Moench) Voss) in 1967 and 1968. Interspecific hybrids were obtained and verified by comparative measurements of several traits. The cross was successful when either species was used as the female parent. Hybrid seed germinated more rapidly than that of either species and hybrid seedlings showed some heterosis for early growth. Also, hybrid seedlings had needles intermediate between, and significantly different from, the parental seedlings. Growth form of the hybrid was quite variable compared with that of either species. Further evidence for the successful crossing of blue spruce and white spruce was provided by biochemical analyses of monoterpene compounds in the parents and progeny.

Diterpene Alcohol

The variation in the relative amounts of the terpenes of the mature and young leaves, buds, and twigs of blue spruce was investigated during a full year. As with the spruces that were investigated previously, large changes were recorded only in the buds and in the young leaves after bud burst. The variations that were recorded in the latter for santene, tricyclene, camphene, camphor, bornyl acetate, and limonene were similar to those that were found in white spruce, but those of car-β-ene, α-pinene, and β-pinene differed. Several quantitative differences in the oil of the winter buds were also recorded. The variation of β-pinene correlated negatively with that of sabinene, γ-terpinene, and terpinolene. A transient diterpene alcohol of the geranylgeraniol type was found in the buds and young twigs during spring. The seasonal variation of the terpenes of the twig oil was smaller than the twig-to-twig variation within a tree. The implications for chemosystematic studies are discussed.

Annotated Checklist

Eight species of mesoplodont whales (genus Mesoplodon Gervais, 1850) named during the nineteenth century are based on valid descriptions. A checklist with the original description and type material for each of these species is provided. Additional data given may include type locality and illustrative sources, type material holding institution and type registration number(s). The only type specimen for which a record of external morphology was published relates to the 1803 stranding of Sowerby's beaked whale (Mesoplodon bidens).

Porphyrin Macrocycles

<p>The synthesis of new graphene-type materials (<i>via</i> polymerization of porphyrin macrocycles) through a simple chemical synthetic pathway (at RT) has been demonstrated. This newly synthesized material can be dispersed in water with an average sheet size of few microns and with single layer thickness. As the porphyrin contains four inner ring nitrogen atoms thus the presented polymeric material will be close analogous of N-doped graphene. Porphyrin as the key component to synthesize layered graphene type continuous 2D structure has never been attempted before. </p> <p> </p>

The fauna of Gryllomorphinae of Turkey is reviewed. Sixteen species and subspecies are established. Ovaliptila anamur sp. nov., O. anitli sp. nov., O. alanya sp. nov., O. alanya proxima subsp. nov., O. alara sp. nov., O. teke sp. nov., O. ibrahimi sp. nov., Glandulosa borisi sp. nov. and Gryllomorpha dalmatina minutissima subsp. nov. are described. Ovaliptila beroni (Popov, 1975), Glandulosa kinzelbachi Harz, 1979, G. harzi Gorochov, 1996 and Gryllomorpha Antalya Gorochov, 2009 are briefly characterized based on the type material. Ovaliptila buresi Mařan, 1958 is indicated as a rather widely distributed species in the western part of Anatolia (but not in the southern coast of this peninsula). Gryllomorpha dalmatina pieperi Harz, 1979, G. miramae Medvedev, 1933 and the nominotypical subspecies of G. miramae are recorded from Turkey for the first time, but both subspecies remain open to question.
