    Abstract From a historical perspective, horse breeding in Bulgaria has been very well developed since the time of the Thracians (early Bronze Age c. 3000 BCE). Archaeological discoveries from this era present us with an extremely rich type diversity, including wild and local primitive horses, the prototype of heavy draft horses, and fine riding horses.The objective of this study was to investigate the genetic structure of unexamined populations of three closely related horse breeds - the Danubian Nonius Hungarian Nonius and Serbian Nonius horses. A 608 bp long fragment of the mtDNA D-loop region was amplified and sequenced. The obtained results showed completely different genetic profiles between the investigated breeds. We identified nine of the 17 haplogroups described in modern horses. Most of the obtained sequences fell into M, L, G, and O'P lineages, which reflects the genetic profiles of the ancestral mares that were probably used at the initial stages of formation of the breeds. The population of the Danubian horse was characterized by a high prevalence of Central Asian specific haplogroup G (45%), followed by Western Eurasian specific haplogroups L and M (both about 21%). In contrast to the Danubian horse, in the Nonius breed the highest frequency of Western Eurasian haplogroup M (43.5%) was found, followed by Middle Eastern haplogroups O'P (26.1%) Central Asian specific E (13.0%) and G (13.1%). The Serbian Nonius horse showed a completely different genetic profile with a prevalence of the rare for Europe haplogroup D (66.7%), followed by Central Asian specific G (16.7%). The high mitochondrial haplotype diversity (Hd = 0.886) found in the investigated samples is evidence for multiple maternal origins in all populations.In conclusion, the obtained results demonstrated a high percentage of haplogroup sharing especially in the Danubian and Hungarian Nonius horse breeds, which reflects the possible common origins of the two breeds. In contrast to these breeds, the Serbian Nonius, despite the small number of investigated animals, showed a specific genetic profile, which could be explained by different and independent origins.

    Abstract The aim of the study is to test a hypothesis for the phylogenetic relationships among mammalian hymenolepidid tapeworms, based on partial (D1-D3) nuclear 28S ribosomal RNA (rRNA) genes, by estimating new molecular phylogenies for the group based on partial mitochondrial cytochrome c oxidase I (COI) and nuclear 18S rRNA genes, as well as a combined analysis using all three genes. New sequences of COI and 18S rRNA genes were obtained for Coronacanthus integrus, C. magnihamatus, C. omissus, C. vassilevi, Ditestolepis diaphana, Lineolepis scutigera, Spasskylepis ovaluteri, Staphylocystis tiara, S. furcata, S. uncinata, Vaucherilepis trichophorus and Neoskrjabinolepis sp. The phylogenetic analyses confirmed the major clades identified by Haukisalmi et al. (Zoologica Scripta 39: 631-641, 2010): Ditestolepis clade, Hymenolepis clade, Rodentolepis clade and Arostrilepis clade. While the Ditestolepis clade is associated with soricids, the structure of the other three clades suggests multiple evolutionary events of host switching between shrews and rodents. Two of the present analyses (18S rRNA and COI genes) show that the basal relationships of the four mammalian clades are branching at the same polytomy with several hymenolepidids from birds (both terrestrial and aquatic). This may indicate a rapid radiation of the group, with multiple events of colonizations of mammalian hosts by avian parasites.

    Abstract The geographical, geomorphological, and climatic characteristics of Bulgaria are particularly favorable for animal breeding and, above all, for pastoral farming and sheep breeding. These conditions created prerequisites for the creation of about 30 unique local breeds of sheep. In this study we investigated the genetic diversity of eight of the most popular Bulgarian native breeds, based on the sequence analysis of a part of the mitochondrial D-loop region. An almost entire mitochondrial DNA (mtDNA) D-loop region (1180 bp) was amplified and sequenced. The obtained results showed the presence of a large number of haplotypes-225, belonging to two main haplogroups. The majority of samples showed a high prevalence of the European haplogroup B (95.2%) while the remaining individuals were assigned to haplogroup A (4.8%). None of the other reported mitochondrial haplogroups were observed. The number of polymorphic sites, nucleotide and haplotype diversity was high (240, 0.01237, and 0.9968, respectively), which is evidence for multiple maternal origins in all populations. The Tajima D-test value in all the study populations was -1.905 (

    Abstract The Western honey bee (Apis mellifera L., Hymenoptera: Apidae) is a species of crucial economic, agricultural and environmental importance. In the last ten years, some regions of the world have suffered from a significant reduction of honey bee colonies. In fact, honey bee losses are not an unusual phenomenon, but in many countries worldwide there has been a notable decrease in honey bee colonies. The cases in the USA, in many European countries, and in the Middle East have received considerable attention, mostly due to the absence of an easily identifiable cause. It has been difficult to determine the main factors leading to colony losses because of honey bees’ diverse social behavior. Moreover, in their daily routine, they make contact with many agents of the environment and are exposed to a plethora of human activities and their consequences. Nevertheless, various factors have been considered to be contributing to honey bee losses, and recent investigations have established some of the most important ones, in particular, pests and diseases, bee management, including bee keeping practices and breeding, the change in climatic conditions, agricultural practices, and the use of pesticides. The global picture highlights the ectoparasitic mite Varroa destructor as a major factor in colony loss. Last but not least, microsporidian parasites, mainly Nosema ceranae, also contribute to the problem. Thus, it is obvious that there are many factors affecting honey bee colony losses globally. Increased monitoring and scientific research should throw new light on the factors involved in recent honey bee colony losses. The present review focuses on the main factors which have been found to have an impact on the increase in honey bee colony losses.
