Iannacone,José;
Gayana (Concepción) , 2003, DOI: 10.4067/S0717-65382003000100002
Abstract: a quantitative research of parasitofauna of thirty-three anuran atelopus bomolochus peters 1973 collected from seco river (80° 9'22'' lw, 5° 5'19'' ls), close to locality of chulucanas, province of morropon, department of piura, peru, in october 2000, was conducted. 13 268 specimens of parasites and seven species in total during all the survey were collected. 28 hosts were parasited (84.8 %). 13 hosts (39.4 %) showed infection with 1 parasite species, six (18.2 %), eight (24.2 %) and one (3,0 %) had two, three and four parasites species, respectively. seven parasite species with the following prevalence of infections were found: gorgoderina parvicava travassos 1922 (digenea) (6.1 %), cylindrotaenia americana jewell 1916 (cestoda) (9.1 %), batracholandros spectatus (freitas & ibá?ez 1962) freitas & ibá?ez 1965 (nematoda) (33.3 %), aplectana hylambatis (baylis 1927) (nematoda) (6.1 %), rhabdias sphaerocephala goodey 1924 (nematoda) (69.7 %), capillaria sp. (nematoda) (39.4 %), centrorhynchus sp. (acantocephala) (3.0 %). b. spectatus was the dominant species (97.8 %). the effect of length with prevalence of infection of r. sphaerocephala, a core specie was found. b. spectatus and capillaria sp. are secondary species. g. parvicava, c. americana, a. hylambatis and centrorhynchus sp. are satellite species. the relationship of helminthes parasites with a. bomolochus is discussed
Annular bone growth in phalanges of five Neotropical Harlequin Frogs (Anura: Bufonidae: Atelopus)
Erik Lindquist,Michael Redmer,Emily Brantner
Phyllomedusa : Journal of Herpetology , 2012,
Abstract: Skeletochronological studies were conducted on museum specimensrepresenting five species of the highly threatened Neotropical genus Atelopus (Bufonidae). We detected annular bone growth (expressed as lines of arrested growth [LAGs]) patterns in each species, and this might provide insight to understand demographic constituency infuture studies. In four of the five species under consideration, LAG counts in fore and hind limb bone occurred in a 1:1 ratio, indicating that bone growth was consistent within each individual. The use of skeletochronology in understanding historic and existing populations of Atelopus might assist in situ and ex situ population managers in making informed strategic conservation plans.
The tadpole of Atelopus pulcher Boulenger (Annura, Bufonidae) from Manaus, Amazonas
Gascon, Claude;
Revista Brasileira de Zoologia , 1989, DOI: 10.1590/S0101-81751989000200007
Abstract: the tadpole of atelopus pulcher is described for the first time. tadpoles of this species were encountered in large streams where reproduction occurs. tadpoles of this species conform to the genus characteristics in exhibiting an enlarged ventral disc and a 2/3 tooth row formula. one characteristic, however, distinguishes this species from other atelopodids in that the upper beak is shorter than the lower beak.
An enigmatic frog of the genus Atelopus (Family Bufonidae) from Parque Nacional Chirripó, Cordillera de Talamanca, Costa Rica
Savage,Jay M; Bola?os,Federico;
Revista de Biología Tropical , 2009,
Abstract: a distinctive new species of atelopus is described from parque nacional chirripó grande, cordillera de talamanca (3 400-3 500 m). it closely resembles populations of the atelopus ignescens complex from the andes of northern ecuador and southern colombia. it differs most significantly from these frogs in the pattern of spiculae and coni development on the throat, chest, hands and feet. the costa rican species appears to be an outlier of the complex inexplicably separated geographically from its nearest allies by an over land distance of about 1 600 km. rev. biol. trop. 57 (1-2): 381-386. epub 2009 june 30.

Se parece a poblaciones del complejo de Atelopus ignescens de los Andes del norte de Ecuador y del sur de Colombia. Principalmente difiere de estas ranas en el patrón de desarrollo de espículas y conos en la garganta, pecho, manos y pies. La especie de Costa Rica es atípica dentro del complejo por estar inexplicablemente separada geográficamente de sus más cercanos representantes por una distancia aproximada de 1 600 km por tierra.
REGISTROS ADICIONALES DE ATELOPUS NAHUMAE Y ATELOPUS LAETISSIMUS PARA LA SIERRA NEVADA DE SANTA MARTA, COLOMBIA

Actualidades Biológicas , 2008,
Abstract: new additional observations of atelopus nahumae and atelopus laetissimus are reported from a locality belonging to the sierra nevada de santa marta (magdalena), colombia; and their ecosystem is characterized. the species are endemic of this area and were listed as critically endangered due to their ecological vulnerability and the absence of verifiable records since 1992. we searched for frogs during the day by visual encounters on a transect 3 x 700 m and obtained data regarding density, activity, and morphometrics of the observed frogs. additionally, the area was explored to gather environmental data and obtain botanic samples. four species of frogs were found (two species each of the genera pristimantis and atelopus) of which 26 individuals were of atelopus nahumae and 12 of atelopus laetissimus. we obtained photographic and audiovisual recordings of atelopus species including calling and amplexus behaviors; both juveniles and apparently healthy adults were observed. the ecosystem is a secondary forest in recuperation, with a closed and continuous canopy with arboreal elements of high strata (25 m), being licania cuspidata (chrysobalanaceae) the most abundant species (38 ind/0.1 ha). in the area there are also plantations of pinus species; however, atelopus individuals were exclusively found in the secondary forest and close to the creek, only pristimantis megalops individuals were found inside the pine forest. this report summarizes the current survival of these populations.

Huertas Vallejos, Lorenzo
Bulletin de l'Institut Francais d'études Andines , 1991,
Abstract: PERTURBATIONS ETHNIQUES A PIURA. Dans cet article nous rendons compte de quelques perturbations ethniques qui se sont produites à Piura à partir de 800 d. C. jusqu'au début du XVIIIème siècle. Ces perturbations étaient provoquées par des causes aussi bien naturelles - tremblements de terre, 'Ni os', sécheresse, etc. - que sociale - guerres, réformes administratives, création d'encomiendas et de villages, etc. Nous avons mis l'accent sur la réorganisation des centres urbains. En este artículo, explicamos algunas perturbaciones étnicas que se produjeron en Piura a partir del a o 800 d. C. hasta inicios del siglo XVIII. Estas perturbaciones habían sido originadas por causas tanto naturales -terremotos, 'Ni os', sequías, etc.- como sociales -guerras, reformas administrativas, creación de encomiendas y pueblos, etc.-, centrando nuestra énfasis en la reorganización de centros urbanos. ETHNIC DISTURBANCES IN PIURA. This article explains some ethnic disturbances which occurred in Piura from the years 800 AC. until the beginning of the XVIII Century. Such alterations were caused by both reasons natural (earthquakes, 'Ni os', droughts, etc) and social (wars, administrative changes, creation of political commissions and villages, etc.), emphasizing the reorganization of urban centers.

Abstract: Se presentan registros adicionales de Atelopus nahumae y Atelopus laetissimus en la Sierra Nevada de Santa Marta (Magdalena), Colombia, y una caracterización actual de su ecosistema. Las especies son endémicas del macizo monta oso y están clasificadas en Peligro Crítico de extinción por su vulnerabilidad ecológica y por la ausencia de registros verificables desde 1992. Mediante registro visual diurno y en un transecto de 3 x 700 m se tomaron datos de densidad, actividad y datos morfométricos de las ranas presentes, además se realizó una exploración del área tomando muestras florísticas y datos ambientales. Se encontraron cuatro especies de ranas (dos de cada uno de los géneros Pristimantis y Atelopus) de las cuales 26 especímenes son de Atelopus nahumae y 12 de Atelopus laetissimus. De las especies de Atelopus se tienen registros fotográficos y audiovisuales con vocalizaciones, amplexos y organismos aparentemente sanos juveniles y adultos. El ecosistema es un bosque secundario en recuperación, de dosel cerrado y continuo con elementos arbóreos de estratos altos (25 m), siendo Licania cuspidata (Chrysobalanaceae) la especie más abundante (38 ind/0,1 ha); también se encuentran plantaciones de especies del género Pinus. Los Atelopus se encontraron exclusivamente en el bosque secundario y el sector de la quebrada, mientras Pristimantis megalops se encontró también en el bosque de pinos. Este reporte permite evidenciar la supervivencia actual de estas poblaciones.

Carvalho, J. de Paiva;
Boletim do Instituto Oceanográfico , 1955, DOI: 10.1590/S0373-55241955000100004
Abstract: this work deals with bomolochus xenomelanirisi n.sp. - copepoda cyclopoida - that was found as parasite on xenomelaniris brasiliensis (quoy & gaimard), a fish inhabiting the south seashore region of s?o paulo state (brazil). on examining 100 fishes, the author found 30 ♀ ♀ and 14 ♂ ♂ , all of which were attached to the internal portion of the posterior region of the opérele. the new species here described is related to bomolochus nitidus and b.exilipes, both described by wilson, but differs from them by the shape of the maxilliped, by the greater number of setae of the first maxilla, by the lenght of the second antennae, by the strongest armature of the first antennae and by the shape and number of the eggs contained in the ovigerous sacs. the author describes male and female, illustrating the descriptions with 21 drawings. some ecological notes are presented. the author is indebted to the national research council (conselho nacional de pesquisas) of rio de janeiro, for a grant in aid, for which thanks are due.
Comunidades y rondas campesinas en Piura
Huber, Ludwig,Apel, Karin
Bulletin de l'Institut Francais d'études Andines , 1990,
Abstract: COMMUNAUTES ET 'RONDAS CAMPESINAS' A PIURA. Les Rondas Campesinas de la sierra du département de Piura se sont formées dans leur grande majorité après les pluies de 1983, qui ont entrainé de graves problèmes économiques et sociaux. Dans ce moment de crise, le vide de pouvoir que comblaient en partie les hacendados dans le passé et que l état ne fut en aucun moment capable de remplir s est manifesté. Les paysans ne disposaient d' aucune organisation sociale propre permettant de remédier à cette crise aigüe. En suivant l exemple de Cajamarca, les Rondas ont réussi à s établir en peu d années comme autorité reconnue par toute la population. Las Rondas Campesinas en la sierra del departamento de Piura surgieron mayormente después de las lluvias del a o 1983, que trajeron graves problemas económicos y sociales. En este momento de crisis se hizo presente un vacío de poder y autoridad, dejado en parte por los hacendados, que el Estado en ningún momento fue capaz de llenar. Los campesinos no contaron con instituciones sociales propias que les hubieran permitido contrarrestar esta situación aguda y conflictiva. Siguiendo el ejemplo de Cajamarca, las Rondas lograron en pocos a os establecerse como autoridad reconocida por toda la población. COMUNITIES AND 'RONDAS CAMPESINAS' IN PIURA. The Rondas Campesinas in the highlands of Piura emerged mainly after the rains of 1983, which caused serious economic and social problems. At this moment of crisis, a vacuum of power was obvious, in part because of the expulsion of the hacendados, which the state was never able to fill. The peasants did not count with a social organization which could have controlled that situation. Following the example of Cajamarca, the Rondas in few years were able to impose an authority accepted by the whole population.
