We report the isolation in the United States of Vibriofluvialis from the stools of a patient who had severe watery diarrhea without fever and who subsequently died. V. fluvialis, a known enteric pathogen in other parts of the world, should be suspected in patients with watery diarrhea, especially in coastal areas. Vibriofluvialis is a newly described halophilic Vibrio species (6) that has been isolated from the stools of over 500 patients with diarrhea at the Cholera Research Laboratory in Bangladesh (now the International Center for Diarrheal Disease Research, Bangladesh) during a 9-month period in 1976 and 1977 (5). It has also been detected in the stools of persons with diarrhea in Jordan, Yugoslavia (6), and Bahrain (3). In the United States, the organism has been isolated from a wound of a patient in Hawaii, from water and sediment in the New York bay (8), from shellfish in Louisiana, and from water and shellfish in Pacific Northwest estuaries (D.

E. y Cruz, M. (2017) Presencia espacial y temporal de aves rapaces diurnas (Aves: Accipitriformes, Falconiformes) en Marismas Nacionales, Nayarit-Sinaloa, México. Acta Zoológica Mexicana (n.s.), 33(1), 27-38. RESUMEN.Las aves rapaces diurnas son un grupo esencial para el equilibrio en las comunidades y pueden ser utilizadas como indicadoras de la calidad del hábitat debido a su sensibilidad a la perturbación. Una de las zonas en México con gran importancia biológica y con graves problemas antropogénicos es Marismas Nacionales. Generar información básica de un grupo ornitológico poco estudiado en Méxi-co y dentro de una zona prioritaria como Marismas Nacionales se hace indispensable para planes de conservación y manejo del área. Por lo que en este estudio se determinó la riqueza espacial y temporal de aves rapaces diurnas durante ocho meses (noviembre de 2010 a junio de 2011) en nueve zonas de Marismas Nacionales. En cada visita se registraron y contabilizaron las especies por sitio y mes. En total se realizaron 945 registros de 22 especies, a las que se añaden cinco más observadas en una visita posterior (enero de 2012) con lo que se tiene una lista de 27 especie. La riqueza en invierno se incrementó con la llegada de cuatro especies migratorias y disminuyó en verano. Las especies más abundantes fueron las de habito necrófago (Cathartes aura, Coragyps atratus) y otra más migratoria (Pandion haliaetus) las cuales conjuntaron en 65% del total de registros. Las zonas con mayor número de especies fueron Zoquipan y las Garzas-Chahuín con 13 y 11 especies respectivamente. En cuanto a registros totales, Zoquipan y Chumbeño presentaron los más altos con 207 para el primero y 185 AbStRACt. Diurnal raptors are an essential group for balance in communities that can be used as habitat quality indicator owing to their sensitivity to disturbance. In Mexico one of the biologically significant areas and that faces serious anthropogenic issues is Marismas Nacionales. Comprehensive management and conservation assessments for the area will require to generate a baseline on poor studied group in Mexico such as raptors. Thus we determined spatial and temporal richness of diurnal raptors through eight months (November 2010 to June 2011) in nine sites of Marismas Nacionales, where we recorded and counted all species per site and month. In that period 945 records of 22 species were made, additionally other five species were observed on a subsequent visit (January 2012) therefore we had 27 species in total. Winter richness increased with the presence of four migratory species and decreased in summer. The most abundant species were the scavengers (Turkey vulture, Black vulture) and one migratory (Osprey); these three species comprised 65% of total records. We found the highest numbers of species in Zoquipan and Garzas-Chahuín (13 and 11 species respectively). In concern of total records, Zoquipan and Chumbeño presented the highest with 207 for the first and 185 the second one. The results shows a high richness of raptors in Marismas Nac...

Spatial and temporal presence of Aramus guarauna (Gruiformes: Aramidae) and Rostrhamus sociabilis (Accipitriformes: Accipitridae) in the Marismas Nacionales Biosphere Reserve, Nayarit, Mexico. Monthly visits were conducted at 12 sites located at Marismas Nacionales (November 2010 to June 2011). In five of them we regularly observed the Limpkin (Aramus guarauna) and in three, the Snail Kite (Rostrhamus sociabilis). The Apple Snail (Pomacea spp.) is abundant in the brackish wetlands and is the most important prey of both species. In 31 observations we recorded 493 limpkins, mainly in Las Cañadas and La Batanga (together: 64% of the records). In March and April we observed flocks of up 80 individuals, in probable relation with the dry season. We obtained 109 records of the kites, always lonely and concentrated in Zoquipan and Mexcaltitan (96%). The presence of the snail in Marismas Nacionales allows both species to expand their range along the Mexican Pacific, at least to the north of Sinaloa, were the lack of fresh water will hinder the establishment of snail populations.

Temporal and spatial distribution of shorebirds (Charadriiformes) at San Ignacio Lagoon, Baja California Sur, Mexico. Baja California Peninsula has several wetlands that represent important ecosystems for shorebirds. San Ignacio Lagoon is one of these sites, and supports 10% of the total abundance of shorebirds reported in this Peninsula. Since there is few information about this group in this area, we studied spatial and temporal changes in abundance and distribution of shorebirds in San Ignacio Lagoon. For this, we conducted twelve monthly censuses (October 2007-September 2008 on the entire internal perimeter of the lagoon, which we divided into four areas: two at the North and two at the South. We observed a seasonal pattern, with the lowest abundance in May (1 585 birds) and the highest in October (47 410). The most abundant species were Marbled Godwits (Limosa fedoa; 55% of the total records), Western Sandpipers (Calidris mauri; 23%), and Willet (Tringa semipalmata; 10%). All three species were more abundant in autumn; for both, the Marbled Godwit and Willet, we observed their highest numbers in winter and spring, while the Western Sandpiper showed noticeable oscillations, reaching a maximum in early winter (December). In summer, Marbled Godwit and Willet were the only birds present but in lower numbers. Here present the first records of the Pacific Red Knot (Calidris canutus roselaari) in the area. Bird abundance and species richness were influenced seasonally by migration and spatially by sites in the lagoon. The greatest shorebird abundance was in the South area of the lagoon, probably because of better accessibility to food. Our results allowed the inclusion of San Ignacio Lagoon in the Western Hemisphere Shorebirds Reserve Network (WHSRN) as a site of international importance. Rev. Biol. Trop. 61 (1): 229-241.

Reportamos la presencia de grupos invernantes de la aguililla de Swainson (Buteo swainsoni) en una región agrícola del municipiode Santiago Ixcuintla, Nayarit. Llevamos a cabo las observaciones durante tres temporadas no reproductivas (2011-2012,2013-2014 y 2014-2015). La abundancia de los grupos varió en cada temporada. En 2012 registramos el menor número de aves:45, y en 2013 el mayor: 364. Realizamos todas las observaciones en campos de cultivo que estaban siendo labrados; las aves losutilizaron como áreas de alimentación y posadero. El aumento de la agrupación del aguililla de Swainson puede deberse al abundantealimento que se expone en los campos arados. En ningún otro momento de la temporada no reproductiva se han reportadotales concentraciones en la región.
