Species of Contracaecum Parasitizing the Magellanic Penguin Spheniscus magellanicus (Spheniscidae) from the Argentinean Coast

Anisakid nematodes have a worldwide distribution and are associated with fishes, birds, and marine mammals from freshwater, brackish, and marine systems. The aims of this work are to report for the first time Contracaecum mirounga parasitizing the Magellanic penguin Spheniscus magellanicus, to report another Contracaecum species in the same host species, and to discuss the validity of Contracaeceum spheniscus. Several dead chicks, juveniles, and adults of S. magellanicus were collected along the Argentinean coast from 2002 to 2009. Nematodes were removed from digestive tracts and studied using both light and scanning electron microscopy. Nematode prevalences were 2.38% for C. mirounga and 12.5% for Contracaecum sp. Contracaecum mirounga was found in 1 penguin from Península Valdés, Chubut. This species is known as a specific parasite of marine mammals such as Pinnipedia, thereby suggesting that this nematode is not as specific as believed. Another species of Contracaecum sp. was found parasitizing 1 penguin from the Río de la Plata coast. It possessed an unusual interlabial morphology and arrangement of male caudal papillae. Despite the low prevalence, the distinct morphological features are convincing and support the presence of a new Contracaecum species. However, a formal description is not presented because sufficient male specimens are lacking. Finally, C. spheniscus is considered a junior synonym of Contracaecum pelagicum. Future molecular studies might be helpful to determine the real diversity of Contracaecum species parasitizing S. magellanicus considering the number of sibling species recognized among the anisakids.Fil: Garbin, Lucas.

On the biological cycle of the gall wasp <i>Plagiotrochus suberi</i> Weld 1926 (Hymenoptera: Cynipoidea: Cynipidae) in the circum-Mediterranean region

Oak gall wasps (Cynipidae: Cynipini: Plagiotrochus) that induce galls on Quercus reproduce by alternate sexual and parthenogenetic generations (Pujade Villar et al., 2001). However, a few species are obligatory parthenogenetic (Abe, 1998) or show the facultative alternation of generations (Folliot, 1964).

ONDE HÁ FUMAÇA, HÁ FOGO! EDUCAÇÃO FÍSICA, FORMAÇÃO E PERSPECTIVA

Este artigo tem como finalidade apresentar alguns dados que nos sugerem questões pertinentes em relação à formação acadêmica em Educação Física (EF) diante do novo cenário do Ensino Superior. A indústria do lazer e do entretenimento constitui uma área em desenvolvimento, que tem gerado emprego, renda, investimentos e tem despertado o interesse de diversos grupos da esfera pública e privada. Paralelamente à isso, há um crescimento vertiginoso de cursos de formação na área que seguem a lógica mercantilista e portanto, baseados em obtenção de lucros que de longe, não significam uma preocupação com um ensino de qualidade. Como procedimento metodológico, foi realizada revisão bibliográfica, caracterizando um tipo de análise que corresponde às pesquisas qualitativas. Podemos considerar que o grande número de vagas no ensino superior e a qualidade duvidosa dos cursos, principalmente de EaD, não possibilitem a inserção de muitos profissionais ao mercado de trabalho, que possivelmente não consegue absorver esse número de graduados, com qualidade e elevação de status profissional

Nuevo hospedador y registro geográfico de <i>Contracaecum australe</i> (Nematoda, Anisakidae) parasitando a <i>Phalacrocorax gaimardi</i> (Aves, Phalacrocoracidae) en costas del Atlántico Sudoccidental

Los nematodes Anisakidae tienen una amplia distribución geográfica a nivel mundial y las especies del género Contracaecum parasitan a organismos acuáticos en diferentes partes del mundo. Contracaecum australe fue descripto por primera vez en el cormorán neotropical Phalacrocorax brasilianus en la laguna Santa Elena, Chile. El objetivo de este trabajo es dar a conocer la presencia de C. australe parasitando el cormorán gris Phalacrocorax gaimardi en las costas de la Ría Deseado, provincia de Santa Cruz, Argentina. Éste es el primer reporte de una especie de helminto en esta especie de cormorán y el registro más austral de la especie C. australe. Por lo tanto se amplía la distribución geográfica y hospedatoria de estos anisákidos.Anisakidae nematodes have a worldwide geographical distribution and the species from the Contracaecum genus have been recorded parasitizing aquatic organisms all around the world. Contracaecum australe was first described parasitizing the Neotropic Cormorant Phalacrocorax brasilianus from Laguna Santa Elena, Chile. The objective of this work is to communicate the presence of C. australe parasitizing the Redlegged Cormorant Phalacrocorax gaimardi on the Ría Deseado coasts, Santa Cruz province, Argentina. This is the first record of a parasite helminth in this cormorant species and the southernmost finding of C. australe. Therefore, the geographical and host distribution of this anisakid species is expanded.Facultad de Ciencias Naturales y MuseoCentro de Estudios Parasitológicos y de Vectore

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Taxonomía y evaluación de la especificidad hospedatoria de nematodos <i>Anisakidae</i> parásitos de aves marinas en el área de Península Valdés, Chubut, Argentina

Los nemátodos Anisakidae tienen una amplia distribución mundial y sus ciclos de vida transcurren principalmente en hospedadores marinos (peces, cefalópodos, reptiles, aves piscívoras y mamíferos). El ciclo de vida generalmente involucra a invertebrados acuáticos como hospedadores intermediarios, peces como hospedadores intermediarios y/o paraténicos, y peces, reptiles, aves y mamíferos marinos como hospedadores definitivos. Hasta el momento, son escasos los antecedentes de investigación de Anisakidae en Argentina, lo cual alentó llevar a cabo las investigaciones del presente trabajo de tesis, para lo cual se planteó estudiar la taxonomía de los nematodos Anisakidae parásitos de aves marinas en Península Valdés, Chubut, Argentina. Las investigaciones se centralizaron en Península Valdés, aunque también se analizó material proveniente de Punta León y Bahía Bustamante (Chubut), Mar del Plata (Buenos Aires) y Cabo Vírgenes (Santa Cruz). Durante los años 2005 al 2008, se colectaron y examinaron un total de 161 ejemplares de Spheniscus magellanicus, 14 de Phalacrocorax atriceps albiventer, 12 de Phalacrocorax atriceps atriceps, 8 de Phalacrocorax brasilianus, 2 de Phalacrocorax magellanicus y 5 de Thalassarche melanophris.Anisakidae nematodes have a world wide distribution and their life cycles take place mainly in marine hosts: fish, cephalopods, reptiles, piscivorous birds and mammals. The life cycle usually involves aquatic invertebrates as intermediary hosts, fish as intermediary and/or paratenic hosts, and reptiles, birds and marine mammals as definitive hosts. At the moment, research reports on Anisakidae in Argentina are scarce which encouraged the research of the present thesis study to be carryed out. The taxonomy of Anisakidae nematodes parasitizing marine birds from Península Valdés, Chubut, Argentina, was outlined to be studied. The research was focused on the Península Valdés even though avian material from Punta León y Bahía Bustamante, Chubut province, Mar del Plata, Buenos Aires province, and Cabo Vírgenes, Santa Cruz province was analized during years 2005 to 2008. A total of 161 individuals of Spheniscus magellanicus, 14 of Phalacrocorax a. albiventer, 12 of Phalacrocorax a. atriceps, 8 of Phalacrocorax brasilianus, 2 of Phalacrocorax magellanicus, and 5 of Thalassarche melanophris were collected and examined.Facultad de Ciencias Naturales y Muse

Species of Contracaecum Parasitizing the Magellanic Penguin Spheniscus magellanicus (Spheniscidae) from the Argentinean Coast

Anisakid nematodes have a worldwide distribution and are associated with fishes, birds, and marine mammals from freshwater, brackish, and marine systems. The aims of this work are to report for the first time Contracaecum mirounga parasitizing the Magellanic penguin Spheniscus magellanicus, to report another Contracaecum species in the same host species, and to discuss the validity of Contracaeceum spheniscus. Several dead chicks, juveniles, and adults of S. magellanicus were collected along the Argentinean coast from 2002 to 2009. Nematodes were removed from digestive tracts and studied using both light and scanning electron microscopy. Nematode prevalences were 2.38% for C. mirounga and 12.5% for Contracaecum sp. Contracaecum mirounga was found in 1 penguin from Peninsula Valdes, Chubut. This species is known as a specific parasite of marine mammals such as Pinnipedia, thereby suggesting that this nematode is not as specific as believed. Another species of Contracaecum sp. was found parasitizing 1 penguin from the Rio de la Plata coast. It possessed an unusual interlabial morphology and arrangement of male caudal papillae. Despite the low prevalence, the distinct morphological features are convincing and support the presence of a new Contracaecum species. However, a formal description is not presented because sufficient male specimens are lacking. Finally, C. spheniscus is considered a junior synonym of Contracaecum pelagicum. Future molecular studies might be helpful to determine the real diversity of Contracaecum species parasitizing S. magellanicus considering the number of sibling species recognized among the anisakids.Facultad de Ciencias Naturales y MuseoCentro de Estudios Parasitológicos y de Vectore
