Immune response to pathogens such as avian malaria ( Plasmodium spp.) and related haemosporidian parasites ( Haemoproteus spp. and Leucocytozoon spp.) can lead to increases in energy demands of birds. Migrations are energetically costly for birds and require resources that could be otherwise invested in immune defence against pathogens. Here, we ex...
Article
Across their ranges, different populations of migratory species often use separate routes to migrate between breeding and non‐breeding grounds. Recent changes in climate and land‐use have led to breeding range expansions in many species, but it is unclear whether these populations also establish new migratory routes, non‐breeding sites and migratio...

The paper presents data on the total biodiversity, the newly described and threatened, rare and invasive species of the complex wetland Atanasovsko ezero, which is situated in the vicinity of the town Burgas on the southern Black Sea coast of Bulgaria. Different parts of Atanasovsko Ezero were declared as Managed Reserve, Ramsar Site, Protected Zon...

The digital edition is part of a joint project for a print and digital edition of the Red Data Book of the Republic of Bulgaria. It includes the full information from the print edition (vol 1 Plants and Fungi, vol 2 Animals, vol 3 Natural habitats), enriched with videos, extended photo gallery, higher-resolution drawings, distribution maps with rel...

DNA barcoding (molecular characterisation) is a useful tool for describing the taxonomy and systematics of organisms. Over 250 species of avian haemosporidian parasites have been described using morphological characters, yet molecular techniques based on polymerase chain reaction (PCR) suggest this diversity is underestimated. Moreover, molecular t...

... A newly established multiplex PCR assay (Ciloglu et al. 2019), based on the simultaneous amplification of gene fragments of the three haemosporidian genera, allows improved detection of mixed infections in birds. Although the multiplex PCR method has been used frequently in recent years (Dimitrov et al. 2019;Inumaru et al. 2020;Ellis et al. 2020;Schumm et al. 2021;Meister et al. 2021), only one paper has addressed the issue of mixed infections in more detail (Neto et al. 2020). ...
... These facts may partially account for the fact that more albino juveniles were encountered in the wild than adults (e.g., Alaminos and López 2011, Martínez-Silvestre and Soler 2018. Nevertheless, albinotic adults of several genera of European snakes, including the genus Natrix, have been observed in the wild (e.g., Sackl and Putz 2002, Krecsák 2008, Alaminos and López 2011, Bruni 2017, Jablonski et al. 2019. Krecsák (2008) posits that there are more aberrant European Viperinae snakes in northern regions than in southern regions; however, we observed the opposite in our review in which the most albinos occurred in central Europe and the Iberian Peninsula with the greatest number of albinos recorded in the genera Zamenis, Vipera, and Natrix. ...
... Die Historie der Erstnachweise vor 1990 lässt es möglich erscheinen, dass Südwestdeutschland durch Expansion französischer Vorkommen zum Beispiel über die Burgundische Pforte nach Südbaden oder weiter nördlich über Lothringen nach Rheinland-Pfalz besiedelt wurde . Wiederfunde von in Ostdeutschland beringten Bienenfressern in Italien, Slowenien und von den Balearen weisen auch auf einen Zusammenhang zu Vorkommen südlich des Alpenhauptkamms hin (Spina & Volponi 2008;Arbeiter et al. 2012;Hahn et al 2020;Hahn & Schulze 2021). Letztlich kann die starke Expansion osteuropäischer Vorkommen bis nach Tschechien und Südpolen ebenfalls Ursprung für Bruten in Deutschland sein, wenngleich die bislang bekannte Hauptzugrichtung von Bienenfressern aus Osteuropa und Sachsen-Anhalt dagegensprechen (Hahn et al. 2020;Hahn & Schulze 2021). ...
... Bulgaria has two main wetland regions that are highly significant for biodiversity and especially for the bird life that migrates through these areas: The Danube wetlands and the Black Sea coastal lakes and lagoons complex 7 . The combination of rich biodiversity with the presence of globally and regionally threatened species proves the outlining of the areas among the most important sites of Bulgarian biodiversity and nature conservation 8 . ...
... We propose to consider the present zonal and extrazonal vegetation types of the above-mentioned locations as approximate analogues of the HTM vegetation of the middle and northern part of the Pannon region. For instance, Plovdiv falls into the northern edge of the distribution of oriental plantain (Platanus orientalis; Biserkov et al., 2015), and the species is not native further north presently. Nevertheless, this species could have occurred until the HTM period in the Pannon region and many other species (Celtis australis, Quercus pedunculiflora, etc.) also could have been present which are now found only south of the Carpathians. ...
... Some new names of doubtful identity were reported in keys. Because of the high genetic diversity of avian Haemoproteus parasites and their relatively high vertebrate host specificity, some of the available synonymous names might be considered valid in the [28,43,91]. This opportunity should be considered during identification of haemoproteids found in birds of these families. ...
