M. deItem Staphylococcus sciuri as a Reservoir of mecA to Staphylococcus aureus in Non-Migratory Seabirds from a Remote Oceanic Island(Microbial Drug Resistance, 2021) Saraiva, Mauro de Mesquita Souza; de Leon, Candice Maria Cardoso Gomes; Silva, Núbia Michelle Vieira da; Raso, Tânia Freitas; Serafini, Patricia Pereira; Givisiez, Patricia Emilia Naves; Gebreyes, Wondwossen Abebe; Oliveira, Celso José Bruno deAim: Genomic analysis of a methicillin-resistant Staphylococcus aureus (MRSA) strain cultured from a non-migratory seabird at Fernando de Noronha Archipelago (Brazilian oceanic islands) was carried out to investigate the potential origin of MRSA genetic determinants in an ecological setting with minimal or absent antimicrobial selective pressure, and minimal interaction with humans and domestic animals. Results: The study determined mecA gene homology and the phylogenetic relatedness with mecA described in Staphylococcus sciuri, which was the major Staphylococcus spp. cultured from the birds. Our findings corroborate in silico assumptions that the mecA gene in MRSA strains clinically relevant for humans and animals originates from S. sciuri ancestors. Conclusion: Coagulase-negative staphylococci seem to be natural reservoirs of methicillin-resistant genes to S. aureus, even in environments with very low antimicrobial selection pressure.Item Spix’s Macaw Cyanopsitta spixii (Wagler, 1832) population viability analysis(Bird Conservation International, 2023) Vercillo, Ugo; Oliveira-Santos, Luiz Gustavo; Novaes, Marisa; Purchase, Cromwell; Purchase, Candice; Lugarini, Camile; Ferreira, Ariane; De Marco, Paulo; Marcuk, Vladislav; Franco, José LuisSpix’s Macaw Cyanopsitta spixii is one of the most endangered Neotropical Psittacidae species. Extinct in the wild in the year 2000, in June 2022 the first cohort of C. spixii was reintroduced to its original habitat. For a successful reintroduction of the species, it is necessary to examine the viability of the population against natural and external threats and the environmental requirements for success. Thus, this paper presents a “Population Viability Analysis” (PVA) for Spix’s Macaw. It used the Vortex and RangeShiftR software, biological and environmental data from a bibliographic survey, and information provided by the field team responsible for the reintroduction of the species, and who work directly with the species in captivity. We found that the minimum viable population (MVP) for reintro duction of the species is 20 individuals. However, considering the impact of disease, drought, hunting, and illegal trafficking, this population can only persist if the release of individuals from captivity occurs annually over the next 20 years combined with the reforestation of natural habitat to support population growth.Item Similar regional‑scale survival of tropical and southern temperate birds from the New World(Oecologia, 2023) França, Leonardo Fernandes; Silva, Clarisse Caroline de Oliveira e; Pinho, João Batista de; Prestes, Nêmora Pauletti; Cueto, Victor R.; Alves, Maria Alice S.; Schunck, Fabio; Fontana, Carla Suertegaray; Lugarini, Camile; Martinez, Jaime; Sagario, M. Cecilia; Casenave, Javier Lopez de; Vecchi, Maurício B.; Repenning, Márcio; Ferreira, Ariane; Dias, Raphael Igor; Passos, Daniel CunhaThe general assumption that the survival patterns of tropical and southern temperate birds are similar lacks empirical data from higher latitudes. Regional comparisons of New World species are rare, and this assumption has been based on data from African studies. Here, we estimate the survival rates of 88 tropical and southern temperate bird populations (69 spe cies) from eight localities in South America to evaluate the hypothesis that the survival of these populations is homogeneous at the regional scale. We estimated survival based on the Cormack-Jolly-Seber model and compared values from diferent environments. The survival estimates ranged from 0.30 to 0.80 (0.56±0.12). Apparent survival did not difer signifcantly between low-latitude tropical environments (03°S) and the other sites from high-latitudes (between 22° and 34°S). Despite a predicted positive trend, body size was not signifcantly related to survival among passerines. On the other hand, phyloge netic relationships explained more than a third of the variation in bird survival. Based on the largest available database on South American bird species, our fndings support the hypothesis that bird survival is homogeneous, at the regional scale, along the southern hemisphere. In particular, we reinforce the hypothesis that climatic variation has a limited infuence on bird survival in the southern hemisphere.Item Terrestrial invasive species on Fernando de Noronha archipelago: What we know and the way forward (Invasive species: Ecology, impacts and potential uses)(Nova Science Publishers, 2020) Micheletti, Tatiane; et al.Item Intentional killing and extensive aggressive handling of albatrosses and petrels at sea in the southwestern Atlantic Ocean(Biological Conservation, 2020) Dimas, Gianuca; Bugoni, Leandro; Jiménez, Sebastián; Daudt, Nicholas W.; Miller, Philip; Canani, Gabriel; Silva-Costa, Augusto; Faria, Fernando A.; Bastida, Julian; Pon, Juan Pablo Seco; Yates, Oli; Serafini, Patrícia P.; Bond, Alexander L.Large Procellariiformes (albatrosses and petrels) constitute a highly threatened group of birds, for which bycatch in fisheries is the most prevalent threat. At-sea intentional killing and post-capture, handling-related injuries, remain poorly understood menaces. Here, we report fishermen off southern Brazil trying to reduce bait depredation in pole-and-line and handlining fisheries by hitting birds with a metal piece attached to a pole-and-line on four occasions. Fishermen also mutilated or killed birds caught alive on the lines (aggressive handling). In addition, we present a compilation of records of Procellariiformes with bill mutilations across the southwest Atlantic Ocean. Related to the intentional killing events, 16 birds of four species (two globally threatened) were recorded dead (n = 13) or injured (n = 3) with head trauma, broken limbs, wounds or bill mutilation. Observations spanning 1999–2019 across the waters of Brazil, Uruguay and Argentina totalize 46 Procellariiformes of eight species (four globally threatened) recorded with bill mutilations (29 alive and 17 dead). Mutilations were likely caused by aggressive handling of birds caught alive, potentially in Brazilian hook-and-line fisheries or in demersal and pelagic longline fisheries across the southwest Atlantic. Observations of deliberate killing from multiple vessels and the recurrent records of mutilated birds suggest those practices represent pervasive but largely undocumented threats to seabirds and could complicate the detection of fishery-related population effects. Coordinated actions by international bodies and national authorities are urgently needed to address this threat, including increasing at-sea observation, enforcement actions and campaigns targeting better handling practices among fishermen.Item NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics(2020) Rosa, Clarissa Alves da; et alBiological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.

P. N. de; Cunha, M. P. V.; Knobl, T.; Cirqueira, C. S.; Dias-Neto, R. N.; Serafini, P. P.; Catão-Dias, J. L.; Díaz-Delgado, J.Cardiovascular disease in avian species, other than poultry, is being increasingly reported. In psittacine birds, atherosclerosis and congestive heart failure are the leading cardiovascular diseases, often resulting in multiorgan dysfunction and demise. The Spix's macaw (Cyanopsitta spixii) is arguably the most endangered psittacine species worldwide. We aimed to describe the gross and microscopic findings in two adult Spix's macaws wherein severe cardiovascular pathology resulted in sudden death. Bird 1 had pathologic findings consistent with fibrinoheterophilic vegetative pulmonic valvular endocarditis with luminal obliterative thrombosis, myocarditis and epicarditis, myocardial fibrofatty infiltration and cardiomyocyte loss, as well as generalized septicaemia. Microbiological analysis yielded Pantoea septica from the intestines and Acinetobacter baylyi from the cerebrum. Bird 2 had changes suggestive of right brachiocephalic coarctation-like obliterative arteriopathy. The latter is a novel cardiovascular pathology in avian species, and its severity and extent likely led to acute decompensation of pre-existing cardiac disease. These results add to the body of knowledge on avian cardiovascular pathology and may aid in veterinary medical decisions on caged birds, including those part of ex situ conservation efforts.Item Ticks (Parasitiformes: Ixodida) on new world wild primates in Brazil(International Journal of Acarology, 2021) Martins, Thiago F.; et alBrazil concentrates the largest number of primate species in the world. In the present study, an extensive literature review of ticks on New World wild monkeys has been carried out, demonstrating that between the years 1912 to 2018, 182 larvae, 137 nymphs and 31 adult ticks (10 males and 21 females) were collected on 78 primates (from 12 different species) in 28 distinct localities in the Brazilian territory. Additionally, examination of allotments of 11 tick collections of Brazil revealed that from 1919 to 2019, 93 larvae, 91 nymphs and 175 adult ticks (62 males and 113 females) were collected from 100 monkeys (among 20 different species) from 43 localities in distinct Brazilian biomes. Overall, 19 tick species were identified on wild primates in the country: Amblyomma aureolatum (Pallas, 1772), Amblyomma cajennense (Fabricius, 1787) sensu stricto, Amblyomma coelebs Neumann, 1899, Amblyomma dubitatum Neumann, 1899, Amblyomma geayi Neumann, 1899, Amblyomma incisum Neumann, 1906, Amblyomma longirostre (Koch, 1844), Amblyomma naponense (Packard, 1869), Amblyomma nodosum Neumann, 1899, Amblyomma ovale Koch, 1844, Amblyomma parkeri Fonseca & Aragão, 1952, Amblyomma romarioi Martins, Luz & Labruna, 2019, Amblyomma rotundatum Koch, 1844, Amblyomma sculptum Berlese, 1888, Haemaphysalis juxtakochi Cooley, 1946, Ixodes fuscipes Koch, 1844, Rhipicephalus microplus (Canestrini, 1888), Rhipicephalus sanguineus (Latreille, 1806) sensu lato,and Ornithodoros rostratus Aragão, 1911. The presence of A. incisum, A. naponense, A. nodosum, A. rotundatum and I. fuscipes on monkeys is recorded for the first time. Thisresearch is therefore a significant contribution to the knowledge of tick speciesassociated with non-human primates in the Neotropical region.
