We report the finding of the flatbug Aradus laeviusculus Reuter, 1875 in the Koli National Park (North Karelia, Finland). One mature female was caught by using a window trap during the period 22.VII.-24.VIII.1996 in a slash-and burning plot that had been burned earlier in summer 1996. A. laeviusculus has been listed as extinct in Finland, the last previous record being from the year 1949 (Lammi, South Finland).

Abstract The altitudinal gradient found in the Atlantic Forest may play a role in establishing sympatry areas between congeneric species of sigmodontine rodents. For some genera with cryptic species, the elucidation of spatial patterns of distribution may be useful to understand reproductive isolation and speciation patterns, as well as spatial and temporal factors determining the boundaries of species’ geographical distributions. Here we evaluated the occurrence of sympatry between Juliomys species along an altitudinal gradient in the Serra da Bocaina National Park (SBNP). Additionally, we review the occurrence of J. rimofrons and add new records of species occurrence in the SBNP, aided by karyological and molecular data. The study was carried out at four sites in the SBNP, which ranged between 770 and 1,200 m a.s.l. We captured 24 Juliomys specimens. Six out of 24 specimens were collected and karyotyped. For J. pictipes, the karyotype had a 2n of 36 and a FN of 34, and for J. ossitenuis 2n of 20 and FN of 36. Seventeen out of 24 Juliomys specimens were used in the cytochrome b phylogeny: 12 specimens grouped with J. pictipes and five with J. ossitenuis. Additionally, a specimen previously identified as J. rimofrons (MN 77793) clustered together with J. pictipes. Juliomys pictipes and J. ossitenuis were found in sympatry in two out of four sites in altitudes higher than 1,000 m a.s.l.. Our karyological and molecular data provided the detection of two Juliomys species in the SBNP for the first time (J. pictipes and J. ossitenuis) and disregarded the previous record of J. rimofrons. Our record of sympatry between J. pictipes and J. ossitenuis represents the fifth known record of sympatry between these species up to date.

A stunted population of Oreochromis mossambicus occurs in the Matiovila Hot Sulphur Spring in the Kruger National Park. The growth of the fishes can best be described by the Von Bertalanffy equation L, = ^^(l-e0154^028^) mm SL. Breeding occurs throughout the year and the smallest sexually mature female was 35 mm SL. The fish from this locality were morphometrically compared to another stunted population and to a population of 0. mossambicus from a large impoundment. Speculative reasons for and advantages of stunting are presented.

Deux Couleuvres à collier adulte (Diadophis punctatus edwardsii) ont été trouvées au parc national du Saguenay, dans l’est du Québec, en 2004 et 2005. Ces mentions se retrouvent à près 150 kilomètres au nord-nord-est de la mention la plus proche de l’espèce. L’habitat est constitué de forêt mixte près d’escarpements rocheux, dans des vallées. Il pourrait s’agir de populations isolées de celles retrouvées plus au sud.Two Ringneck Snakes (Diadophis punctatus edwardsii) was found in the Saguenay National Park, in eastern Québec, in 2004 and 2005. These records are about 150 kilometers north-north-east from the nearest previous record. The habitat is mixed forest, with rocky cliffs, in valleys. They may represent isolated populations from those found in southern Quebec.

Although the general ultrastructure of Cyanidium caldarium, an acidophilic, thermophilic alga of questionable taxonomic rank, has been extensively studied (see review of literature in reference 1), some peculiar ultrastructural features of the chloroplast of this alga have not been noted by other investigators.Cells were collected and prepared for thin sections at the Yellowstone National Park and were also grown in laboratory cultures (45-52°C; pH 2-5). Fixation (glutaraldehyde-osmium), dehydration (ethanol), and embedding (Epon 812) were accomplished by standard methods. Replicas of frozenfracture d- etched cells were obtained in a Balzers apparatus. In addition, cells were examined after disruption in a French Press.
