2. The status of a rare phylogeographic lineage of the vulnerable European souslik Spermophilus citellus, endemic to central MacedoniaPeter Glasnović, Boris Kryštufek, Svetozar Petkovski, 2012, short scientific article Abstract: The conversion of grasslands for agriculture has triggered a serious decline of the European ground squirrel or souslik Spermophilus citellus, categorized as Vulnerable on the IUCN Red List since 1996. The Jakupica phylogeographic lineage of central Macedonia is the smallest of the three major evolutionary lines of the European souslik. This lineage is an important reservoir of within-species diversity and should be regarded as an independent unit for conservation management purposes. It is endemic to Mount Jakupica, where it lives in mountain pastures at 1,500-2,250m altitude. The total area occupied by sousliks (884 ha) is fragmented and 94% of individuals occur in four colonies. Densities (0.8-5.5 adults ha-1) are lower than those reported elsewhere for the species, with the total population probably ,2,000 adults. One large colony, reportedly of c. 1,000 sousliks, was decimated in 2007 by a catastrophic fire and had still not recovered bz 2010. A steady decline in livestock grazing, together with the predicted advance of the tree line as a consequence of climate change, will probably reduce the optimal habitat for the souslik and negatively affect population fitness. Monitoring needs to be implemented, at least for the largest colonies, to provide early warning of any declines

3. Female reproductive characteristics of the Horvath's rock lizard (Iberolacerta horvathi) from SloveniaPeter Glasnović, Katarina Ljubisavljević, Katja Kalan, Boris Kryštufek, 2012, original scientific article Abstract: In this paper, we present data on the female reproductive traits of the Horvath's rock lizard from Slovenia. The clutch, egg and hatchling characteristics were investigated based on clutches laid in laboratory conditions by pregnant females collected from a natural population. A female lays one clutch of eggs annually with an average number of three (range 1-5) eggs. We found a significant positive correlation between female size and egg width and volume. The mean egg length and volume in a clutch decreased significantly with clutch size independently of female size. The incubation period averaged 44 days. Significant positive correlations were found between the hatchling total length and mass, and egg mass. There was a significant negative relationship between the egg mass and incubation duration. The life-history strategy of the Horvath's rock lizard appeared to be shaped by several factors, such as the constraints of a high-altitude environment, flattened body morphology and possibly phylogenetic background

4. Novosti iz adventivne flore Slovenske IstrePeter Glasnović, Jernej Jogan, 2012, original scientific article Abstract: V članku je predstavljenih nekaj novih nahajališč adventivnih vrst v Slovenski Istri. Najverjetneje prehodno pojavljanje na južni meji areala imajo vrste Dasypyrum villosum, Hedysarum coronarium in Piptatherum miliaceum s po enim novoodkritim nahajališčem, medtem ko so najverjetneje z vrtov ušle Iris foetidissima, Periploca graeca in Soleirolia soleirolii, prvi dve s po enim in slednja z več novimi nahajališči. Hedysarum coronarium in Periploca graeca sta bili prvič zabeleženi v flori Slovenije

6. Akebia quinata (Houtt.) Dcne., nova vrsta v slovenski flori, ter prispevek k poznavanju neofitske flore PrimorskePeter Glasnović, Živa Fišer, 2010, original scientific article Abstract: The article discusses Akebia quinata, a new alien species for the Slovenian flora. The authors provide a description of the species and its locality, and discuss its invasive potential, as in 2008, the species was recognized by the European and Mediterranean Plant Protection Organization as emerging invader in Europe. The authors also discuss the occurrence of several other neophytes in the Primorska region (Slovenia): Amaranthus deflexus, Artemisia annua, Aster squamatus, Bidens pilosa, Bidens subalternans, Broussonetia papyrifera, Pistia stratiotes and Senecio inaequidens.
