The population structure of the highly mobile marine mammal, harbor porpoise (Phocoena phocoena), in Atlantic shelf waters follows a pattern significant isolation-by-distance. porpoises from Baltic Sea, which is connected with North Sea through series basins separated by shallow underwater ridges, however, more complex. Here, we investigated differentiation European Seas special focus on and adjacent waters, using genomics approach. We used 2872 single nucleotide polymorphisms (SNPs),...
We detected a highly pathogenic avian influenza A(H5N8) virus in lung samples of 2 gray seals (Halichoerus grypus) stranded on the Baltic coast Poland 2016 and 2017. This virus, clade 2.3.4.4 B, was closely related to H5N8 viruses circulating Europe at time.
Knowing the abundance of a population is crucial component to assess its conservation status and develop effective plans. For most cetaceans, estimation difficult given their cryptic mobile nature, especially when small has transnational distribution. In Baltic Sea, number harbour porpoises (Phocoena phocoena) collapsed since mid-20th century Proper porpoise listed as Critically Endangered by IUCN HELCOM; however, remains unknown. Here, one largest ever passive acoustic monitoring studies...
Harbour porpoise (Phocoena phocoena), the only resident cetacean species of Baltic Sea is formed two subpopulations populations, occurring in western Baltic, Belt Seas and Kattegat Proper, respectively. porpoises throughout these areas are exposed to a large number human activities causing direct indirect effects on individuals, that might also harm this population level. From Latvia, Poland, Germany Denmark 385 out 1769 collected dead harbour were suitable for extensive necropsy. The...
Abstract In the present study 5 grey seals (Halichoerus grypus), 3 common (Phoca vitulina) and 1 ringed seal (Pusa hispida) bycaught or stranded on Polish Baltic Sea coast in years 2000-2006 were investigated for infestation of parasitic anisakid nematodes. 749 anisakids found. The most were: Contracaecum osculatum (59.3%) Pseudoterranova decipiens (31.0%). There also small numbers Anisakis simplex (0.8%). After performing RFLP three sibling species C. was identified as C, P P. sensu stricto...
The grey seal became locally extinct in the southern Baltic Sea, Danish Straits and Kattegat early 1900s after prolonged culling campaigns. Here, we combine national monitoring anecdotal data from Denmark, Sweden, Germany Poland to report on seal's recolonisation of those areas initial reestablishment breeding colonies. Grey occurrence has steadily increased since year 2003 as evidenced by coordinated Sea moult censuses. At first census 2003, there were 146 seals along coasts Sweden ca 1%...
Harbour seals (Phoca vitulina) and grey (Halichoerus grypus) are final hosts of acanthocephalans in the German North Baltic Seas. Parasitic infections can cause pathological changes, which may result deteriorated health host. Common gastrointestinal parasites harbour a number 275 2460 (11.2%) investigated from 1996 to 2013 were infected with Corynosoma spp. (Acanthocephala, Polymorphidae). The prevalence showed wave-like pattern: it increased 1.2% 0.4% 1997, respectively, 23.9% during second...
In-air anthropogenic sound has the potential to affect grey seal (Halichoerus grypus) behaviour and interfere with acoustic communication. In this study, a new method was used deliver signals seals as part of an in-air hearing assessment. Using in-ear headphones adapted ear inserts allowed for measurement auditory brainstem responses (ABR) on sedated exposed 5-cycle (2-1-2) tone pips. Thresholds were measured at 10 frequencies between 1–20 kHz. Measurements made using subcutaneous electrodes...
Grey seals Halichoerus grypus and harbour Phoca vitulina are common seal species in the North Baltic seas final hosts of Corynosoma acanthocephalans. C. strumosum magdaleni infect small intestines both species. In contrast to seals, grey past have regularly displayed severe semerme infections caecum colon, with associated tunica muscularis hypertrophy, inflammation ulcerations as part disease complex (BSDC). Pathogenesis correlation acanthocephalan these lesions still unknown. This study...
Evaluating populational trends of health condition has become an important topic for marine mammal populations under the Marine Strategy Framework Directive (MSFD). In Baltic Sea, recommendation Helsinki Commission (HELCOM), efforts have been undertaken to use blubber thickness as indicator energy reserves in mammals. Current values lack geographical representation from entire Sea area and a large dataset is only available grey seals ( Halichoerus grypus ) Sweden Finland. Knowledge on...
Abstract The Harbour porpoise ( Phocoena phocoena ) is a highly mobile cetacean species primarily occurring in coastal and shelf waters across the Northern hemisphere. It inhabits heterogeneous seascapes broadly varying salinity temperature. Here, we produced 74 whole genomes at intermediate coverage to study porpoise's evolutionary history investigate role of local adaptation diversification into subspecies populations. We identified ~6 million high quality SNPs sampled eight localities...
The common harbor porpoise is a widely-distributed marine mammal with three known subspecies, including P. phocoena phocoena, clearly distinct and critically endangered (CR) subpopulation from the Baltic Sea (Baltic Proper). As part of an assessment condition health threats these mammals, it important to conduct parasitological monitoring. aim study was therefore compare data on parasitofauna this those porpoises other areas. included 37 individuals 1995 2019; eight species parasites were...
SAMBAH (Static Acoustic Monitoring of the Baltic Sea Harbor Porpoise) is an EU LIFE + -funded project with primary goal estimating abundance and distribution critically endangered harbor porpoise. From May 2011 to April 2013, members in all countries around undertook a static acoustic survey using 304 porpoise detectors distributed randomly positioned systematic grid waters 5–80 m deep. In recorded data, click trains originating from porpoises have been identified automatically algorithm...
Abstract The present study describes a finding of the demodecid mite Demodex phocidi in seal Phoca vitulina Baltic Sea. This is first identification Europe and second world. also observation Demodecidae family pinnipeds outside North America. A high density mites was observed skin examined seal, but no symptoms parasitosis were observed. Our findings supplement taxonomic description morphometry D. .
