We report the first record of presumed twinning in eastern bluebird (Sialia sialis) and provide a review of all previously reported twinning events in wild birds. A nest containing twin eastern bluebird nestlings was monitored in 2013 in central Pennsylvania and reported to the Cornell Lab of Ornithology’s NestWatch program, a national program where volunteers submit data on wild nesting birds. A presumed double-yolked egg of a free-living eastern bluebird pair hatched successfully, and twin nestlings lived for 11 days in a nest box shared by three siblings. Due to the rarity of twinning in wild birds, engaging the public to monitor large numbers of nests is the most likely approach to documenting twinning in wild populations, and citizen science provides the infrastructure for individuals to share observations.

Increasing Demand

Vast numbers of crustaceans are produced by aquaculture and caught in fisheries to meet the increasing demand for seafood and freshwater crustaceans. Simultaneously, the public is increasingly concerned about current methods employed in their handling and killing. Recent evidence has shown that decapod crustaceans probably have the capacity to suffer because they show responses consistent with pain and have a relatively complex cognitive capacity. For these reasons, they should receive protection. Despite the large numbers of crustaceans transported and slaughtered, legislation protecting their welfare, by using agreed, standardized methods, is lacking. We review various stunning and killing systems proposed for crustaceans, and assess welfare concerns. We suggest the use of methods least likely to cause suffering and call for the implementation of welfare guidelines covering the slaughter of these economically important animals.

ABSTRACTThe religious reforms of the sixteenth century exerted a profound impact upon the liturgy of baptism in England. While historians' attention has been drawn to the theological debates concerning the making of the sign of the cross, the new baptism liturgy contained within the Book of common prayer also placed an innovative importance on the public performance of the rite in the presence of the whole congregation on Sundays and other holy days. Both religious radicals and conservatives contested this stress on ceremony and publicity throughout the early modern period. Through the collection of large numbers of baptism dates from parish registers, it is possible to measure adherence to these new requirements across both space and time. Before the introduction of the first prayer book in 1549, there was considerable uniformity among communities in terms of the timing of baptism, and the observed patterns are suggestive of conformity to the requirements of the late medieval church. After the mid-sixteenth century, parishes exhibited a range of responses, ranging from enthusiastic adoption by many communities to complete disregard in religiously conservative parts of Lancashire and Cheshire. Additionally, the popularity of saints' festivals as popular days for baptism fell markedly after 1660, suggesting a decline in the observance of these feasts.

Abstract A description is provided for Aspergillus fumigatus. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Common as a saprophyte in soil and fermenting vegetable matter. Pathogenic to mammals (including man), birds and insects. DISEASES: The most serious diseases caused by this fungus are the acute and chronic infections of the respiratory system (aspergillosis, aspergilloma) of man (Austwick, 1965; and many other references, e.g., RMVM 3, 677; 4, 316; 4, 549, 551) and animals (Ainsworth & Austwick, 1959; Austwick, 1965). It may also infect the cardiovascular, digestive, genital, musculoskeletal, nervous, and urinary systems, such infections usually following haematogenous spread of the pathogen from a primary focus in the lungs or air sacs. It is the most common cause of mycotic abortion in cattle (Ainsworth & Austwick, 1959; Austwick, RMVM 5, 660; Dijkstra; RMVM 5, 92) and less often in horses (Hensel et al. ; RMVM 4, 1227). Aspergillus fumigatus may also infect the ear (otomycosis) and mastoid cavity, the eye and sinuses (mycoses). Aspergillosis is a major disease of birds and is a cause of considerable losses in the poultry industry, particularly of very young birds (brooder pneumonia) (Vertinskii et al. ; RMVM 5, 758; Vallejo; 5, 940). It is also common in captive wild birds, especially water birds (Ainsworth & Rewell; RMVM 1, 2090; Dathe; 4, 1948; Saez; 4, 811), but reports of infections in free-living wild birds are more rare (Beer; RMVM 4, 2177; McDiarmid; 2, 1761; Rosen, 5, 558). A. fumigatus also invades eggs. Aspergillus fumigatus spores may induce allergic reactions in man, resulting in hay fever, asthma or allergic bronchopulmonary aspergillosis. It also produces toxins (Ainsworth & Austwick, 1959; Austwick, 1965). GEOGRAPHICAL DISTRIBUTION: World-wide. TRANSMISSION: Soil and air-borne. Disease incidence appears to be related to heavy infection from house dust, mouldy hay or straw, litter, or feeding stuffs (Austwick, 1965; Austwick, RMVM 5, 3b).

AbstractRecently, multiple spillover events between domesticated poultry and wild birds have been reported for several avian viruses. This phenomenon highlights the importance of the livestock-wildlife interface in the possible emergence of novel viruses. The aim of the current study was to investigate the potential spillover and epidemiological links of infectious bursal disease virus (IBDV) between wild birds and domestic poultry. To this end, twenty-eight cloacal swabs were collected from four species of free-living Egyptian wild birds (i.e. mallard duck, bean goose, white-fronted goose and black-billed magpie). Genetic and phylogenetic analysis of three positive isolates revealed that the IBDV/USC-1/2019 strain clustered with previously reported very virulent IBDV (vvIBDV) Egyptian isolates. Interestingly, two other wild bird-origin isolates (i.e. IBDV/USC-2/2019 and IBDV/USC-3/2019) grouped with a vaccine strain that is being used in commercial poultry. In conclusion, our results revealed the molecular detection of vaccine and vvIBDV-like strains in Egyptian wild birds and highlighted the potential role of wild birds in IBDV epidemiology in disease-endemic regions.

Program nasional pemberdayaan masyarakat mandiri kelautan dan perikanan pada sektor perikanan diwujudkan dalam bentuk pengembangan usaha mina pedesaan. Program penanggulangan kemiskinan melalui pemberdayaan masyarakat kelautan dan perikanan seringkali tidak tepat sasaran dan tidak memperhitungkan keberlanjutan program sehingga kemiskinan tidak berkurang bahkan semakin bertambah. Pengembangan Usaha Mina Perdesaan (PUMP) merupakan salah satu program Kementerian Kelautan dan Perikanan (KKP) ditujukan untuk menanggulangi kasus kemiskinan pada kelompok masyarakat tertentu. Tujuan penelitian ini adalah untuk menganalisis pelaksanaan Pengembangan Usaha Mina Perdesaan (PUMP) pada kelompok masyarakat pengolah dan pemasar hasil perikanan di Kota Banda Aceh, mengetahui respon masyarakat terhadap Pengembangan Usaha Mina Perdesaan Pengolahan dan Pemasaran Hasil Perikanan (PUMP P2HP), dan mengidentifikasi faktor-faktor yang mempengaruhi pelaksanaan program tersebut. Penelitian ini menggunakan pendekatan kualitatif dan pengumpulan data dilakukan melalui wawancara, observasi dan desk study. Pengambilan sampel ditentukan secara purposive dengan responden anggota kelompok pengolah dan pemasar hasil perikanan (POKLAHSAR) penerima program. Metode analisis data dilakukan secara deskriptif. Hasil penelitian menunjukkan bahwa pelaksanaan PUMP P2HP di setiap tahapannya secara normatif memang telah terlaksana dan terdapat kesesuaian antara ketentuan pedoman program dengan pelaksanaannya di masyarakat. Namun demikian, dalam hal pelaksanaannya sebagai sebuah program pemberdayaan, secara substansi masih jauh dari tujuan yang diharapkan. Hal ini didukung dengan analisis mengenai respon masyarakat terhadap pelaksanaan program, baik itu mengenai keberlanjutan program, keterlibatan dalam program, manfaat program, dan konflik selama pelaksanaan program. Faktor-faktor dominan yang dapat menghambat pelaksanaan program ini secara keseluruhan perlu dilakukan perubahan dan perbaikan. Faktor yang menjadi penghambat dan penunjang keberhasilan program yaitu kesesuaian lokasi, pemberian peralatan yang menunjang produksi, dan ketepatan calon penerima bantuan. Rekomendasi kebijakan untuk perbaikan pelaksanaan program bantuan langsung tunai (BLT) di masa depan yaitu (1) Penyederhanaan dalam prosedural kegiatan program, (2) Ketepatan pemilihan calon penerima, (3) Pelatihan dan pendampingan kepada para calon penerima maupun penerima bantuan, dan (4) Evaluasi terhadap program bantuan untuk pengembangan usaha dan kemandirian penerima bantuan secara berkelanjutan. (Implementation of The National Program for Marine and Fisheries Community Empowerment in The Fisheries Processing Business : A Case Study in Banda Aceh City)Fish business development in the village level is considered as the natural program for marine and fisheries community empowerment. Poverty reduction programs through marine and fisheries community empowerment are does not effective and take into account the sustainability of the program so that poverty can not be reduced even increasing. National program of marine and fisheries in the fish processing business are considered one of the MMAF program intended to eliminate poverty in a certain society. The aims of this study was to analyze implementation of PUMP P2HP, particularly in Banda Aceh City, identify the public response to the PUMP P2HP, and identify factors that affect the implementation of the program. This research used a qualitative approach and data collection through interview, observation and desk study. Sample was determined using purposive sampling with respondents “kelompok pengolah dan pemasar” (POKLAHSAR) members participating in the program. The method of data analysis was carried out descriptively. Results show that the implementation of PUMP P2HP in each stage have indeed been implemented as in the guidelines on the implementation of programs in the community. However, in terms of its implementation as a policy of empowerment, it is still far from the expected goals. This is supported by an analysis of the public response to the implementation of the program, in relation to the sustainability of program, the participation in program, the benefits of program, and conflict occurred during implementation of the program. The dominant factors that can support and prevent the implementation of the program as a whole, that the implementation procedures should be be changed and improved. Inhibitory and supporting factor for success of the program were namely the suitability of the location, provision of equipment to support the production, and the accuracy of the prospective beneficiaries. Policy recommendations to improve implementation of the programs of direct cash assistance (BLT) in the future were identified as follows: (1) simplification of the program process, (2) accuracy in selecting candidates (3) training and assistance to the recipients and beneficiaries, and (4) evaluation of the programs for business development and self-reliance of beneficiaries sustainable manner.

Host Parasite

Variation in environmental factors such as parasitism can have direct effects on an organism’s fitness. Because parasites draw resources directly from their hosts, they are expected to have negative effects; however, several nestling host – parasite systems show no evidence of direct effects. Absence of direct effects may be explained by compensation strategies used by parents or nestlings themselves. In this study evidence for both direct effects and compensatory strategies in a blow fly (genus Protocalliphora Hough, 1899) – Eastern Bluebird (Sialia sialis (L., 1758)) system were examined. Nestlings showed no direct effects of blow flies on survival and on size at fledging; however, parasitized broods were significantly anemic. There was no evidence for compensation by parents in the form of brood reduction and there was no support for compensation by nestlings via a hierarchy of tissue preservation. Nestlings did compensate for parasitism by accelerating growth at the end of the nestling period and delaying fledging.
