Description
An account of the resource
En Antofagasta, norte de Chile, coexisten dos especies de ostreros: Haematopus palliatus pitanay (ostrero blanco) y Haematopus ater (ostrero negro). Ambas especies depredan en un sistema rocoso intermareal peculiar cuya franja media se encuentra dominada por el tunicado Pyura praeputialis (= Pyura stolonifera bradleyi; Kott 1997). En la literatura se discute sobre las diferencias morfológicas del pico (largo y ancho) entre ambos tipos de ostreros. Dichas diferencias podrían segregar los roles de forrajeo de estas aves cuando comparten un mismo hábitat: los ostreros blancos atacarían preferentemente a presas de textura 'blanda' y los ostreros negros atacarían presas de textura 'dura' (i.e. cobertura calcárea). En este trabajo se consideró a P. praeputialis (piure de Antofagasta) como una presa de textura 'blanda', ya que su tunica, compuesta por tunicina, es suave y flexible. En el estudio se comparan diversos aspectos ecológicos entre ambas especies de ostrero tales como: (a) abundancia de ostreros y de otras aves costeras que depredan sobre P. praeputialis, (b) distribución espacial de los ostreros en el manto de piure durante sus actividades de depredación, (c) tallas de piures preferidos, (d) tiempos de manipulación, (e) tasa de consumo y (f) frecuencia de consumo de otros invertebrados distintos del piure. Los resultados señalan a H. palliatus pitanay como la especie de ostrero que ataca con mayor frecuencia a P. praeputialis. Por otra parte, H. ater ataca con mayor frecuencia presas de textura 'dura' como: lapas, caracoles, choritos, erizosAt Antofagasta, northern Chile, two oystercatcher species coexist: the white oystercatcher, Haematopus palliatus pitanay and the black oystercatcher H. ater. Both species forage on an intertidal system where the middle fringe is dominated by the tunicate Pyura praeputialis (= Pyura stolonifera bradleyi; Kott 1997). According to the literature, differences in the morphology of their bills (length and width) segregate the foraging roles of white and black oystercatchers when the birds coexist in the same habitat. H. palliatus pitanay is best adapted for capturing soft bodied preys, while black oystercatcher H. ater attack 'hard' preys (i.e. preys with calcareous shells). We consider here that the tunicate P. praeputialis as a soft bodied prey because the tunic, composed of tunicine, is soft and pliable. We compare ecological aspects between the two oystercatchers species in Antofagasta, such as: (a) abundance of oystercatchers and other coastal birds preying on P. praeputialis, (b) the spatial distribution of the oystercatchers in the Pyura bed during foraging periods, (c) Pyura size preferences of oystercatchers, (d) handling time, (e) consumption rate and (f) preference of other invertebrates prey items distinct from Pyura. The results show that H. palliatus pitanay attacks more frequently Pyura than H. ater, and that H. ater attacks more frequently 'hard' preys such as: limpets, snails, mussels and sea urchins.

Description
An account of the resource
La enfermedad del moko de las musáceas, causada por la bacteria Ralstonia solanacearum, es uno de los problemas fitopatológicos más importantes de la agroindustria del banano en los países tropicales. En Urabá y el Magdalena (Colombia), las principales regiones exportadoras de banano en Colombia, esta enfermedad provoca una destrucción estimada en 16.5ha/año. La bacteria presenta un nivel extremadamente alto de variación genética que afecta las medidas de control. Este es el primer estudio de su variación en Colombia y se hizo con los marcadores moleculares AFLP en una población de 100 aislamientos de plantas de banano, suelos y arvenses. El alto nivel de diversidad genética, con índices de Nei y de Shannon de h=0,32 y I=0,48, respectivamente, y la AMOVA, demostró que esta población es subestructurada (Fst=0,66): el hospedero es el principal factor de diferenciación. Aun así, las pruebas anteriores mostraron que todas las variedades presentan patogenicidad en Musa.Genetic variability of the bacterium Ralstonia solanacearum (Burkholderiales: Burholderiaceae) in the banana-growing region of Uraba (Colombia). The banana moko disease, caused by the bacterium Ralstonia solanacearum, is one of the most important phytopathological problems of the banana agribusiness in tropical countries. In Uraba and Magdalena (Colombia), the main exporting regions of banana in Colombia, this disease causes a destruction estimated in 16.5ha/year. The bacterium presents an extremely high level of genetic variation that affects control measures. This is the first study of its variation in Colombia and was done with AFLP molecular markers on a population of 100 isolates from banana plants, soils and 'weeds'. The high level of genetic diversity, with Nei and Shannon indexes of h=0.32 and I=0.48, respectively, and the AMOVA, showed that this population is subestructured (Fst=0.66): the host is the main factor of differentiation. Even so, previous tests show that all varieties have pathogenicity on Musa. Rev. Biol. Trop. 58 (1): 31-44. Epub 2010 March 01.

Girardinichthys multiradiatus, conocido comúnmente como 'mexcalpique' un pequeño pez endémico de la cuenca del río Lerma, cuya presencia en el parque Nacional Lagunas de Zempoala, sugiere una antigua conexión entre estos lagos y la cuenca. El área de distribución actual en la porción del valle de México y Toluca se ha visto reducida, por lo que este parque representa un refugio para la especie. Sin embargo, se conoce poco de la biología del mexcalpique. Presentamos datos sobre su dieta y hábitos alimentarios. El estudio se realizó en el Lago Acoyotongo del Parque Nacional Lagunas de Zempoala mediante muestreos estacionales. La identificación del contenido estomacal (97 ejemplares) se llevó hasta el taxón más específico posible. Para la cuantificación se utilizaron los métodos numérico y frecuencia de aparición. La dieta general de esta especie se encuentra constituida por doce componentes alimenticios, de los cuales once son de origen animal. Himenópteros, colémbolos y quironómidos fueron los que presentaron los mayores porcentajes de ingestión y preferencia. Esta es una especie carnívora con tendencias insectívorasThe feeding ecology of the endemic fish Girardinichthys multiradiatus (Cyprinidontiformes: Goodeidae) in Lagunas of Zempoala National Park, Mexico. Girardinichthys multiradiatus, locally known as 'mexcalpique', is a small endemic fish of the Lerma river basin. Its presence in lakes (Zempoala) suggests a long-standing connection between these lakes and the river basin. The current range of this species in the Mexico and Toluca valley appears to have been reduced, making this park a refuge for the species. Nevertheless, little is known about its biology. We studied its diet and feeding habits in Acoyotongo Lake, Lagunas de Zempoala National Park (19°01’30'-19°06’ N, 99°16’20'-99°21’ W) where seasonal collections were carried out. The gut contents of 97 specimens were identified to the most specific taxonomic category possible and analyzed with numeric and frequency of occurrence methods. The general diet of this species consists of twelve dietary components, eleven of which are of animal origin. Hymenopterans, springtails and chironomids represented the highest percentage of ingestion and preference. G. multiradiatus is as a carnivorous species with entomophagous tendencies. Rev. Biol.

Description
An account of the resource
Los grupos más expuestos a la Inseguridad Alimentaria y Nutricional son los que figuran en cualquier lista de 'desposeídos'. Las familias más afectadas son aquellas más vulnerables a la degradación del medio ambiente, que viven en malas condiciones sanitarias, de contaminación y superpoblación; cuando esto se asocia al grupo materno infantil la vulnerabilidad queda reforzada. Si importante es la cantidad de personas con subnutrición y desnutrición, también lo es definir: quiénes son, dónde están, los alimentos que suelen consumir y las causas del problema - soluciones. Nuestra caracterización de los posibles grupos vulnerables en Brasil sigue dos perspectivas: datos relacionados con la pobreza y los criterios para la clasificación de grupos vulnerables de la FAO (perspectiva que refiere criterios personales, pues no existen abordajes de este tipo en la literatura científica). La alta concentración de renta de Brasil hace que los pobres tengan escasos recursos para comprar una cesta básica de alimentos, implicando mayor vulnerabilidad. Se pueden observar diferencias entre: áreas urbanas y rurales, áreas no-metropolitanas y metropolitanas, y entre las regiones nordeste y norte en relación con las demás. Cabe destacar las importantes influencias étnicas, culturales y migratorias que sobre estos grupos de personas pesan y que los hacen vulnerables.The more exposed people to Food and Nutritional Insecurity comprise the list of the 'dispossessed'. The most affected families are the ones more vulnerable to environment degradation, living in bad sanitary conditions, contamination and high demographic rates; when this is associated to the maternal and children group vulnerability becomes more accentuated. The quantification of malnourished and undernourished people is as important as determining who they are, where they are, their food habits and the causes and solutions for the problem. Our definition of possible vulnerable groups in Brazil follows two perspectives: poverty related data and FAO's vulnerable group classification (perspectives containing personal criteria, for there are no approaches of the type in scientific literature). High income concentration in Brazil results that the poor have insufficient resources to buy food implying in more vulnerability. There are differences between: urban and rural areas, metropolitan and non-metropolitan areas, and between the Northeast and Northern regions as related to other regions. There are important ethnic, cultural and migration factors involving the more vulnerable groups.

Description
An account of the resource
We present an analysis of behavioral flexibility in a day-active caviomorph rodent, the degu, Octodon degus, in response to temporal (daily and seasonal), spatial, and thermal heterogeneity of its environment. We quantified activity and foraging behavior in a population, together with thermal conditions, in an open habitat in the seasonally hot and arid matorral of central Chile. Summer activity was bimodal, with a gap of more than 8 h between the morning bout of 2.5 h of intensive foraging and the afternoon bout of 2 h. More than half of the 4.5 h of summer activity occurred in the shade of early morning or late afternoon when the sun was below the local skyline. Autumn and spring activity were also bimodal, but with greater proportions of activity under direct solar radiation, and with a shorter midday gap between the two major bouts. Winter activity was unimodal and all occurred under direct solar radiation. In summer, autumn, and spring the activity of degus was curtailed as our index of operative temperature, Te, moved above 40 ºC. We used a single measurement of Te (measured in a thermal mannequin representing degu size, shape and surface properties) as an index of the interactive effects of solar radiation and convection on body temperature. At the winter solstice (June), when degus remained fully exposed to solar radiation throughout the day, Te generally remained below 30 ºC. Flexibility in the timing of surface activity allows degus to maintain thermal homeostasis and energy balance throughout the year. Degus shift the times of daily onset and end of activity and the number of major bouts (unimodal or bimodal) over the course of the year. They remain active on the surface under a much narrower range or 'window' of thermal conditions than those that occur over the entire broad range of the day and yearPresentamos un análisis de la flexibilidad conductual en la actividad diaria del degu (Octodon degus), un roedor caviomorfo, en respuesta a la heterogeneidad del ambiente temporal (diario y estacional), espacial y térmico. Junto con las condiciones térmicas, cuantificamos la conducta de actividad y forrajeo en una población que vive en un hábitat abierto en el matorral árido y estacional de Chile central. La actividad de verano fue bimodal, con 2,5 h de actividad de forrajeo intenso durante la mañana y con 2 h durante la tarde. No hubo actividad por mas de 8 h entre ambos eventos. Más de la mitad de las 4,5 h diarias de actividad de la mañana y de la tarde ocurrieron en la sombra, cuando el sol se encuentra bajo la línea local del cielo. La actividad durante el otoño y la primavera también fue bimodal pero con una mayor proporción de actividad bajo radiación solar directa y con un período de inactividad menor entre los dos eventos principales. La actividad de invierno fue unimodal y bajo radiación solar directa. En verano, otoño y primavera la actividad estuvo sesgada cuando nuestro índice de temperatura operativa, Te, superó los 40 °C. Usamos una medida de Te (registrada en un maniquí térmico que representa las propiedades de forma, tamaño y superficie de un degu) como un índice de los efectos interactivos de la radiación solar y la convección sobre la temperatura corporal. Durante el solsticio de invierno (junio), cuando los degus permanecieron todo el día totalmente expuestos al sol, Te generalmente permaneció bajo 30 °C. La flexibilidad en el tiempo de la actividad superficial le permitió a los degus mantener su homeostasis térmica y balance de energía anual. Los degus cambiaron sus períodos de inicio y término así como el número de eventos de actividad (unimodal o bimodal) durante el año. Estos roedores permanecieron activos en la superficie bajo un rango mucho más estrecho de condiciones térmicas que las que ocurren durante el largo del día y año

Este estudo objetivou levantar preliminarmente os escarabeíneos copro-necrófagos da região de Brejo Novo, Caruaru, Pernambuco, e verificar aspectos da estrutura da comunidade como sazonalidade, diversidade, equitabilidade, riqueza e abundância das espécies. Foram realizadas 10 coletas, com intervalos de 30 dias e duração de 48 horas, de setembro de 2003 a julho de 2004. Utilizaramse 24 armadilhas de queda, com dois tipos de isca, fezes humanas e carne bovina em estado de putrefação. Foram coletados 1.540 indivíduos pertencentes a seis tribos, 12 gêneros e 28 espécies. As espécies Canthon af. carbonarius, Canthon chalybaeus, Dichotomius nisus, D. semisquamosus, Digitonthophagus gazella e Eurysternus hirtellus aparentemente são as mais adaptadas ao ambiente estudado. Foram coletados 826 indivíduos em armadilhas iscadas com fezes humanas e 714 em carne bovina apodrecida. Ocorreu um número maior de espécies consideradas 'raras' (15), sendo três destas 'singletons', duas 'doubletons' e 10 com abundância entre três e 10 indivíduos, 13 espécies foram consideradas 'comuns'. Das espécies analisadas, sete apresentaram hábitos alimentares generalistas, quatro são estritamente coprófagas e uma estritamente necrófaga. Foram verificadas correlações positivas entre a precipitação mensal e a abundância e a riqueza de espécies. O levantamento preliminar das espécies de Scarabaeinae da região de Brejo Novo contribuiu para aumentar o número de espécies registradas para o estado de Pernambuco e região Nordeste do Brasil.This paper reports the results of the preliminary survey of copro-necrophagous dung beetles of Brejo Novo region, Caruaru, Pernambuco, as well as some aspects of the community structure such as seasonality, diversity, equitability, richness and abundance of species. Ten samplings with intervals of 30 days and duration of 48 hours, fortnightly were done between September 2003 to July 2004. Scarab beetles were collected with 24 pitfall traps baited with two types of baits, human excrements and rotting bovine meat. A total of 1,540 individuals belonging to six tribes, 12 genera and 28 species were collected. The species Canthon af. carbonarius, Canthon chalybaeus, Dichotomius nisus, D. semisquamosus, Digitonthophagus gazella and Eurysternus hirtellus are, apparently, adapted to the studied environment. Traps baited with human excrements attracted 826 individuals and those with rotting bovine meat attracted 714 specimens. Large number of species (15) considered 'rare' occurred, being three of them 'singletons', two 'doubletons' and 10 with abundance between three and 10 individuals; 13 species were considered 'common'. Of the analyzed species, seven present generalist alimentary habits, four are strictly coprophagous and one is strictly necrophagous. Positive correlations were verified between the precipitation and the abundance of the individuals and the species richness. This preliminary survey of the dung beetles of the Brejo Novo region contributed to increase the number of species registered for Pernambuco and northeast region of Brazil.

Description
An account of the resource
Este estudio in situ observa la utilización de hábitat y ecología alimenticia de tres taxa pertenecientes al complejo de especies Amphilophus citrinellus (mojarra) en la Laguna de Xiloá. Históricamente, ha habido gran confusión con respecto a la taxonomla de A. citrinellus. Varias formas de A. citrinellus han sido identificadas dentro de la cuenca de los grandes lagos de Nicaragua. Esta investigación plantea que tres formas de A. citrinellus existen en la Laguna de Xiloa. Estas tres formas, ahora clasificadas como Unidades Evolutivas Significantes (ESU por sus siglas en Inglés), han sido nombradas provisionalmente con los nombre de 'barlowi', 'long-dark' y 'amarillo . Entre ellas se encontraron diferencias significativas en términos de utilización de micro-hábitat y dietas, así como en la sobrevivencia de crías y los distintos micro-hábitat.

Description
An account of the resource
The feeding of Engraulis anchoita was studied in the coastal reproductive habitat of the northern population during the spawning period. Stomach contents of anchovy adults and plankton samples taken during a research cruise were examined. The highest stomach fullness values were found in the Rio de la Plata estuary, particularly at stations close to the surface salinity front. Copepods, particularly those < 1 mm total length, represented by Paracalanus spp. and Oithona spp., were the most abundant prey. The dominance of small copepods in the Argentine anchovy diet is noted for the first time. Ecological implications of this fact are discussed. Other abundant preys were appendicularians, cladocerans, and fish eggs. The species composition of the zooplankton samples coincided roughly with that found in the stomach contents. However, selective feeding was observed on preys > 1 mm total length. This might be explained by a low gill rakers efficiency of adult anchovies to retain small prey. In the Rio de la Plata front, both the reported large biomasses of zooplankton and the observed intense anchovy feeding revealed the ecological significance of this front, especially when compared with the contiguous 'poor in food' coastal areas.Se estudió la alimentación de la población norteña de Engraulis anchoita en el hábitat reproductivo costero durante su periodo de desove. Se analizaron los contenidos estomacales de adultos de anchoíta y muestras de zooplancton tomados durante un crucero de investigación. Los mayores valores de repleción estomacal se encontraron en el estuario del Río de la Plata, particularmente en estaciones cercanas al frente salino de superficie. Los copépodos fueron las presas más abundantes, particularmente especímenes < 1 mm de longitud total, representados por Paracalanus spp. y Oithona spp. Este dominio de pequeños copépodos en la dieta de la anchoíta argentina se destaca por primera vez. Se discutieron las implicancias ecológicas de este hecho. Otras presas abundantes fueron: apendicularias, cladóceros y huevos de peces. La composición de especies en las muestras de zooplancton coincidió a grandes rasgos con las encontradas en los contenidos estomacales. Sin embargo, se observó selección sobre presas > 1 mm de longitud total. Esto se puede explicar por la baja eficiencia del aparato branquial de anchoítas adultas para retener pequeñas presas. En el frente del Río de la Plata, las altas biomasas de zooplancton reportadas y la intensa alimentación observada, evidencian su significancia ecológica, especialmente cuando se compara con aguas costeras adyacentes pobres en alimento.

An account of the resource
El evento 'El Niño 1997-98' mostró una evolución rápida y de gran intensidad, resultando uno de los más fuertes ocurridos sobre el Pacífico Ecuatorial Central y Oriental en los últimos 150 años. En la costa peruana el calentamiento del agua de mar inducido por 'El Niño 1997-98' empezó en marzo de 1997, con la incursión de aguas subtropicales y ecuatoriales. Las condiciones atmosféricas y oceánicas a macroescala se mantuvieron y alcanzaron su máxima intensidad en noviembre y diciembre de 1997. La Zona de Convergencia Intertropical estuvo desplazada al sur de su posición normal, en gran parte del año 1997. 'El Niño' afectó el clima del país desde inicios del otoño de 1997. El invierno resultó uno de los más cálidos de la historia peruana, con anomalías que alcanzaron hasta los 6°C en la costa central. Asimismo, se registraron caídas de presión atmosférica en el Pacífico Oriental; lluvias que superaron significativamente sus promedios en la parte media y alta de la costa norte del Perú; y lluvias normales o ligeramente deficientes en la sierra, particularmente en el sur del país.

Description
An account of the resource
No Brasil, biodiversidade - em especial, a diversidade vegetal - é considerada importante fonte de riqueza. Inequivocamente, porém, qualquer retribuição durável em benefícios sociais dependerá não do uso da biodiversidade, mas sim de seu uso sustentável. Descrições regionais da fauna e da flora constituem um primeiro passo nessa direção. Quando utilizadas para mapeamento e quantificação da biodiversidade, permitem interpretar os mecanismos de funcionamento da natureza. Sem a compreensão desses mecanismos o 'desenvolvimento sustentado' permanecerá o que é hoje: apelo político sem retribuição social (Beardsley, 1994). Nossos trabalhos pretendem fornecer segura base teórica para esclarecer esse 'mais maravilhoso mistério da vida, o meio pelo qual tanta diversidade surgiu de tão pouca matéria física' (Wilson, 1992). Afinal, 'como podemos executar a política nacional - ou até mesmo tomar decisões inteligentes sobre nossas próprias vidas - se não compreendemos as questões subjacentes' (Sagan, 1996)? Trata-se de problema autenticamente brasileiro que necessita da urgente unificação de esforços, porque de sua solução dependem aplicações práticas diretas para garantia do bem-estar socioeconômico e da saúde do povo.In Brazil biodiversity, specially plant diversity, is considered an important source of wealth. Clearly, however, any enduring retribution in social benefits does not depend simply on the use of biodiversity, but on its sustainable use. Regional descriptions of fauna and flora constitute a first step in this direction. Utilized for mapping and quantification of biodiversity, such descriptions allow mechanistic interpretations of the functioning of nature. Without the understanding of these mechanisms 'sustainable development' remains what it is today: a political appeal without social retribution (Beardsley, 1994). Our efforts aim to provide a secure theoretical basis for the elucidation of this 'most marvellous mystery of life, the means by which so much diversity was generated from so little physical material' (Wilson, 1992). After all, 'how can you carry out a national policy - or even make intelligent decisions on your own life - if you do not understand the underlying questions' (Sagan, 1996)? This is a genuine Brazilian problem requiring an urgent gathering of efforts, since it has direct practical applications on the socio-economical well-being and the health of the people.
