| an fpga-based wasn for remote real-time monitoring of endangered species: a case study on the birdsong recognition of botaurus stellaris. | fast environmental variations due to climate change can cause mass decline or even extinctions of species, having a dramatic impact on the future of biodiversity. during the last decade, different approaches have been proposed to track and monitor endangered species, generally based on costly semi-automatic systems that require human supervision adding limitations in coverage and time. however, the recent emergence of wireless acoustic sensor networks (wasn) has allowed non-intrusive remote moni ... | 2017 | 28594373 |
| helminth communities of herons (aves: ardeidae) in southern italy. | the helminth communities of nine species of herons from southern italy were studied and compared. of 24 taxa found including seven digeneans, seven nematodes, six cestodes and four acanthocephalans, only five taxa were found in more than one heron species, and five of the 21 taxa that could be identified to species level were classified as 'heron specialists'. the total number of helminth species per heron species ranged from 1 in botaurus stellaris to 9 in ixobrychus minutus with infection leve ... | 2016 | 27091547 |
| avian tuberculosis in naturally infected captive water birds of the ardeideae and threskiornithidae families studied by serotyping, is901 rflp typing, and virulence for poultry. | avian tuberculosis was detected in one flock of 38 water birds of the families ardeideae (n = 20) and threskiornithidae (n = 18). mycobacterium avium subsp. avium (maa, serotype 1, genotype is901+ and is1245+) was more often (p = 0.01) detected in tissue and/or faecal samples in 18 (90.0%) birds form the ardeideae family: little egret (egretta garzetta), buff-backed heron (bubulcus ibis), great white egret (egretta alba), and bittern (botaurus stellaris) in comparison to two (11.1%) birds from t ... | 2007 | 17056210 |
| composition, structure and pattern of helminth assemblages associated with central european herons (ardeidae). | helminths parasitizing the ardeid birds are poorly understood, and the majority of studies are limited to checklists and records of novel host-parasite interactions. here we analyzed the prevalence, intensity and diversity of the helminth component communities associated with an extensive cohort of the five most common czech herons (ardea cinerea, ardea alba, nycticorax nycticorax, botaurus stellaris and ixobrychus minutus) collected in the years 1962-2013. comparison with ukrainian datasets sup ... | 2015 | 25449288 |
