2. Bober (Castor fiber) v SlovenijiBoris Kryštufek, Andrej Hudoklin, Dušan Pavlin, 2006, original scientific article Abstract: Bober je bil v Sloveniji zanesljivo prisoten od interglaciala Riss/Würm pa vse do 17-18. stoletja, ko ga je iztrebil človek. Prva pobuda za njegovo ponovno naselitev (1992) zaradi pomanjkanja sredstev ni zaživela. Bober se je tako naselil v Sloveniji po naravni poti, kot posledica naselitev bavarskih bobrov na Hrvaško, ki so se začele leta 1996. Prva naselbina je bila zabeležena pozimi 1998/1999 v spodnjem toku Radulje, ob izlivu v Krko. Bober je odtlej stalno prisoten na tem območju. Prvo razmnoževanje smo zabeležili leta 2001, pozimi 2003/2004 pa so se bobri ustalili tudi v zgornjem delu Krke. Oktobra 2002 se je bober pojavil tudi na Dobličici, kjer se je prav tako ustalil. Oba habitata sta za bobra suboptimalna glede kakovosti vode, brežin in prehranske osnove, močna pa je prisotnost človeka. Škode in konflikti so na obeh območjih zmerne. Obe naselbini sta opredeljeni kot območji NATURA 2000.V zadnjih dveh letih se je bober pojavil tudi na Sotli (2005), Muri (2005) in Dravi (2006). Populacija bobrov v Sloveniji predstavlja obrobje hrvaške populacije.

9. Phylogenetic position of the Ohiya rat (Srilankamys ohiensis) based on mitochondrial and nuclear gene sequence analysisElena Bužan, Marie Pagès, Johan Michaux, Boris Kryštufek, 2011, original scientific article Abstract: We investigated the phylogenetic position the Ohiya rat, endemic to Sri Lanka, Srilankamys (Rodentia, Murinae), within the tribe Rattini based on the combined analysis of three independent genes (a mitochondrial one and two nuclear exons). Three major lineages (the Maxomys, the Dacnomys and the Rattus divisions) were retrieved as monophyletic groups within the tribe Rattini. Srilankamys was not affiliated to any of the representatives of the Dacnomys division as it was supposed based on morphological characters, but clearly appeared as the first genus to diverge among the Rattus division. The Mindanao Shrew Mouse, Crunomys melanius, emerged as a part of the Maxomys division raising questions about the validity of the Crunomys and the Maxomys divisions as currently defined. Molecular date of divergence between Srilankamys and the other representatives of the Rattus division falls within the interval 6.7 +- 0.74 Mya, coinciding with the time of the isolation of Sri Lanka from the Deccan peninsula and the aridification period owing to the climate change at the end of the Miocene epoch. We suggest that the isolation of Sri Lanka from the continent, reinforced by the action of a seasonal monsoon-dominated climate, would have led to the isolation of some ancestral rodents of the Rattus division, which would have differentiated later into the Ohiya rat by a vicariant process. In a more general point of view, our study supports the previous results obtained on other organisms and evidence that Sri Lanka appears to be characterized by a particular fauna as compared to the Indian mainland. This island would therefore be considered as a specific distinct hotspot of biodiversity
