AbstractDiversity at 35 allozyme loci was examined in nine populations of the taxa currently included in Darevskia saxicola. The data support the recognition of the subspecies Darevskia s. saxicola and D. s. lindholmi as species. The remaining subspecies D. s. brauneri, D. s. darevskii and D. s. szczerbaki are conspecific although they can no longer be referred to Darevskia saxicola, but must be referred to Darevskia brauneri, whose name has priority. Considerable population substructuring was observed among the subspecies of Darevskia brauneri.

Flavipanurgus is a small genus of panurgine bees known only from the Iberian Peninsula. Despite its status as one of the few bee genera endemic to Europe, Flavipanurgus are poorly represented in collections and until recently, their ecology had been almost unknown. Flavipanurgus ibericus (Warncke, 1972) was described from southern Iberia, with a northern subspecies F. i. kastiliensis (Warncke, 1987) later described from the north. Recent collections in Portugal have revealed clear differences in the pollen collecting patterns of the two taxa, with southern females collecting exclusively from Jasione montana and northern females from Sedum species. In combination with this ecological difference, COI and 28S barcode data indicate that Flavipanurgus kastiliensis stat. nov. should be raised to full species status. The male of Flavipanurgus ibericus s. str. is described for the first time, and updated keys to Flavipanurgus species are provided. Flavipanurgus fuzetus Patiny, 1999 is recorded for the first time from Spain. Further significant records and new floral associations for Flavipanurgus are also presented.

The methyl derivatives of broth cultures of black-pigmented Bacteroides were examined by gas chromatography for production of phenylacetic acid. Two serogroups of B. melaninogenicus ssp. intermedius described by Lambe differed in the ability to produce phenylacetate. Serogroup C failed to produce phenylacetic acid while serogroup C-1 produced small amounts of phenylacetate, which contributed 2.2–5.7% to the total nonvolatile acid profile. Holdeman's newly proposed species "B. intermedius" and "B. corporis" correspond to serogroups C and C-1, respectively. These data support the elevation of the two serogroups of B. melaninogenicus ssp. intermedius to species status. Bacteroides gingivalis produced phenylacetate in significantly larger quantities than B. corporis. Bacteroides melaninogenicus ssp. melaninogenicus, "B. melaninogenicus ssp. levii," and B. asaccharolyticus did not produce phenylacetic acid. These results indicate that phenylacetic acid production may be useful in distinguishing "B. corporis" and B. gingivalis from the other black-pigmented Bacteroides.

In vitro collapse of DNA by trivalent cations like spermidine produces torus (donut) shaped DNA structures thought to have a DNA organization similar to certain double stranded DNA bacteriophage and viruses. This has prompted our studies of these structures using freeze-etch low Pt-C metal (9Å) replica TEM. With a variety of DNAs the TEM and biochemical data support a circumferential DNA winding model for hydrated DNA torus organization. Since toruses are almost invariably oriented nearly horizontal to the ice surface one of the most accessible parameters of a torus population is annulus (ring) thickness. We have tabulated this parameter for populations of both nicked, circular (Fig. 1: n=63) and linear (n=40: data not shown) ϕX-174 DNA toruses. In both cases, as can be noted in Fig. 1, there appears to be a compact grouping of toruses possessing smaller dimensions separated from a dispersed population possessing considerably larger dimensions.
