[email protected] Servicio Nacional de Meteorología e Hidrología del Perú- SENAMHI DOI: https://doi.org/10.33017/RevECIPeru2012.0025/ Resumen Clasificar un tipo de clima es un reto en selva media y baja, donde las variaciones solo se dan por influencia del crecimiento de las ciudades o los procesos de deforestación y por ello las metodologías de selección de climas no son suficientes para delimitar microclimas[1]. Por lo que; el objetivo principal del trabajo de investigación fue implementar una propuesta a nivel de microclima en función al tipo de vegetación predominante en la cuenca del río Itaya, el cual está flanqueado por dos principales ríos; Amazonas y Nanay. Se trabajaron con 47 estaciones climatológicas, que fueron ubicados dentro y fuera de la zona de estudio. Se utilizaron termohigrómetros digitales para el monitoreo de los puntos de muestreo. La metodología utilizada fue basado en Thornthwaite (1949)[2], para ello se dispuso de los valores mensuales de evapotranspiración, precipitación y temperaturas de la serie consecutiva de 35 años. Para realizar la propuesta de complementación a nivel de microclima se registraron variables como rango térmico, temperaturas mínimas y la humedad relativa. Determinándose un total de 19 microclimas. Los resultados muestran que los microclimas dependen del tipo de vegetación, en especial, de tipo aguajales en donde existe menor número de microclimas y son homogéneos, mientras que, en colinas predominan mayores oscilaciones térmicas heterogéneas y finalmente en zonas deforestadas existe una variedad de microclimas heterogéneos propios de su entorno. Por lo que este sistema de clasificación climática complementario a la metodología tradicional permite caracterizar microclimas en selva baja. Palabras clave: microclima, propuesta, bosques, Itaya. Abstract Classify a type of climate is a challenge in medium and low forest where variations occur only under the influence of the growth of cities or deforestation processes and therefore the selection of climates methodologies are not sufficient to define microclimas [1]. So, the main objective of the research was to implement a proposed micro-level according to the predominant vegetation type in the Itaya River basin, which is flanked by two major rivers Amazon and Nanay. We worked with 47 weather stations were located inside and outside the study area. Thermohygrometers were used for monitoring digital sampling points. The methodology used was based on Thornthwaite (1949) [2], it was available for the monthly values of evapotranspiration, precipitation and temperatures of 35 consecutive series. To make the proposal to complement micro-level variables were recorded as thermal range, minimum temperature and relative humidity. Determining a total of 19 microclimates. The results show that the microclimates depend on the type of vegetation, especially aguajales type where there are fewer of microclimates and are homogeneous, while in hills dominate over thermal fluctuations and finally heterogeneous deforested areas there are a variety of microclimates heterogeneous to their environment. So this climate classification system complementary to the traditional methodology for characterizing micro-climates in the lowlands. Keyword: microclimate, proposal,forests,Itaya.

Os estilos fluviais refletem a fisiografia estrutural da rede de drenagem controladas pelos estratos rochosos, retratando na paisagem sua dinâmica, assim como os padrões de canais, que podem ser alterados por processos geomorfológicos, climáticos e antrópicos. O quadro dos estilos fluvial fornece um modelo geomorfológico dos processos espaciais e temporais biofísicos para gestão e planejamento das bacias hidrográficas. O presente trabalho teve como objetivo analisar as influências do comportamento no canal da bacia do rio Una localizado no Nordeste do Estado de Pernambuco, a partir da investigação das feições da drenagem como reflexo da transferência de matéria e energia entre distintos compartimentos e setores do ambiente fluvial.  A metodologia proporcionou uma visão geral de toda área analisada, a partir da avaliação do índice de sinuosidade, mapeamento dos estilos e das feições fluviais, perfis longitudinais e trabalhos de observação em campo. Assim, constatou-se que a influência estrutural na rede de drenagem da referida bacia comandou a retilineidade do canal Una, com quebra no gradiente topográfico, inflexão do canal e vales encaixados. Nesse ambiente, verificou-se que a produção e deposição dos sedimentos estão vinculados as influências do clima tropical.

The fluvial styles of the table provides a geomorphological model of spatial processes and biophysical time for planning and management of river basins. This study aimed to analyze the influence of behavior on the channel of the river basin Una located in the northeastern state of Pernambuco, from the investigation of drainage features reflecting the transfer of matter and energy between different compartments and sections of the river environment. The methodology provided an overview of the whole analyzed area, from the evaluation of the sinuosity index, mapping styles and river features, longitudinal profiles and field observation work. Thus, it was found that the structural influence on the basin drainage network commanded the straightness of Una channel, breaking the topographic gradient, channel inflection and enclosed valleys. In this environment, it found that the production and deposition of sediments are bound influences the tropical climate.

O objetivo deste estudo é avaliar o estado de conservação das Áreas de Preservação Permanentes (APPs) de nascentes da bacia hidrográfica do rio Jauru (BHRJ), no Estado brasileiro de Mato Grosso. Para tanto, foram utilizadas ferramentas geotecnologicas para identificação das nascentes e delimitação de suas APPs, conforme os dispostos da Lei 12.651/2012. A mensuração do estado ambiental de conservação da paisagem foi realizada por meio da aplicação do Índice de Transformação Antrópica (ITA). No período de três décadas (1986-2016), foi identificado na BHRJ um constante processo de supressão vegetal, tendo um decréscimo de 90%, em decorrência do desmate para o desenvolvimento da implantação da pecuária, principal atividade econômica dos municípios que compõem a bacia. O ITA evidenciou que sete das nove sub-unidades hidrográficas estão em estado degradado. A bacia do rio Jauru apresentou desmatamento crescente durante o período analisado, incluindo suas APPs. Diante disso, a necessidade de planejamento do uso da terra na bacia é de extrema importância ambiental, visto sua contribuição hídrica ao bioma Pantanal. Palavras-chave: Geotecnologias. Pantanal.

For this, geotechnological tools were used to identify the springs and delimit their APPs, according to those in law 12.651/2012. The measurement of the environmental state of conservation of the landscape was performed through the application of the Anthropic Transformation Index (ITA). In the period of three decades (1986-2016), a constant process of plant suppression was identified in BHRJ, with a decrease of 90%, due to the decrease in the development of livestock activity, the main economic activity of the municipalities that make up the basin. The ITA showed that seven of the nine hydrographic subunits are in a degraded state. The Jauru River basin showed increasing deforestation during the analyzed period, including its APPs. Therefore, the need to plan land use in the basin is extremely environmentally important, given its water contribution to the Pantanal biome.  Keywords: Geotechnologies. Pantanal.

The problems of modern geological ecology associated with the study of pollution of sediments of water bodies by heavy metals are considered. The Volga River basin is quite heterogeneous, both in geomorphological and hydrological terms, and in thechnogenical development and usage. A fourrank taxonomy is presented for the selection of sites for monitoring, based on a combination of natural, landscape, climatic and thechnogenical factors. To the largest – the highest taxon – sites of the Ist category – bowls of reservoirs with the slopes and the urban zones, industrial and agricultural structures located within them are carried. Within these areas are allocated to smaller taxa, areas category IInd are the industrial and urban zones, areas category IIIrd are the small rivers without significant contamination and areas category IVth to conduct special observations. The examples of special observations in the study of the annual migration of heavy metals in the system «bottom sediments – water column» on the Ivankovo reservoir are highlighted. The investigations were carried out under the conditions of the standard flow rate for this reservoir and in the conditions of slow water exchange.

The transnationalization of television production has been examined by studies on formats and multinational media companies, which have often highlighted the resilience of the local in the global. This article investigates transnationalization on the micro level of television production, drawing on participant observations in a Dutch production company that is partly owned by an American conglomerate. It explores the deep entanglement of the local with the global in different facets of production – including legal, organizational and market aspects – as manifested in daily practices and decision-making in television production. Our analysis reveals an industrial logic of formatting that is not only induced by transnational ownership structures and business models but also deeply ingrained in production routines and programme conventions. Through this logic, transnationalization shapes media professionals’ daily work, the selection of programme ideas and the process of content development.

Abstract The atmospheric water balance over the semiarid Murray–Darling River basin in southeast Australia is analyzed based on a consecutive series of 3- to 24-h NWP forecasts from the Australian Bureau of Meteorology’s Limited Area Prediction System (LAPS). Investigation of the LAPS atmospheric water balance, including comparison of the forecast precipitation to analyzed rain gauge observations, indicates that the LAPS forecasts capture the general qualitative features of the water balance. The key features of the atmospheric water balance over the Murray–Darling Basin are small atmospheric moisture flux divergence (at daily to annual time scales) and extended periods during which the atmospheric water balance terms are largely inactive, with the exception of evaporation, which is consistent and very large in summer. These features present unique challenges for NWP modeling. For example, the small moisture fluxes in the basin can easily be obscured by the systematic errors inherent in all NWP models. For the LAPS model forecasts, there is an unrealistically large evaporation excess over precipitation (associated with a positive bias in evaporation) and unexpected behavior in the moisture flux divergence. Two global reanalysis products (the NCEP Reanalysis I and the 40-yr ECMWF Re-Analysis) also both describe (physically unrealistic) long-term negative surface water budgets over the Murray–Darling Basin, suggesting that the surface water budget cannot be sensibly diagnosed based on output from current NWP models. Despite this shortcoming, numerical models are in general the most appropriate tool for examining the atmospheric water balance over the Murray–Darling Basin, as the atmospheric sounding network in Australia has extremely low coverage.

<p>El objetivo de este trabajo es evaluar la pertinencia de la métrica dental para obtener información sexual en individuos que habitaron el curso inferior del río Colorado durante el Holoceno tardío (ca. 3000-250 años AP), discutir el grado de dimorfismo sexual e identificar las variables cuantitativas de la dentición que permitan discriminar el sexo de nuevos individuos que se incluyan en futuros análisis. Se estudiaron las medidas máximas bucolinguales y mesiodistales del cuello de los dientes correspondientes a 26 individuos adultos. Las variables más dimórficas corresponden al diámetro bucolingual del canino superior y de ambos segundos molares; en estos casos, las diferencias entre los sexos son estadísticamente significativas. Los resultados obtenidos sobre el dimorfismo sexual se ubican en el extremo superior de los valores correspondientes a diferentes poblaciones humanas. Varios individuos que no contaban con información sexual a través de los métodos tradicionales pudieron ser clasificados desde la métrica dental, lo cual da cuenta del importante potencial de las medidas dentales para contribuir a las caracterizaciones paleodemográficas de conjuntos bioarqueológicos, especialmente en contextos perturbados y con escasa integridad esqueletal.</p><p>Palabras clave: métrica dental; determinación sexual; cazadores-recolectores; curso inferior del río Colorado; Holoceno tardío.</p><p>Abstract<br />The aim of this paper is to evaluate the relevance of dental metrics for obtaining sexual information in individuals who inhabited the lower basin of the Colorado River during the Late Holocene (ca. 3000-250 years BP), to discuss the degree of sexual dimorphism and to identify those quantitative variables adequate for sexual determination of new individuals to be included in future studies. The buccolingual and mesiodistal maximum neck diameters of 26 individual adults were studied. The most dimorphic variables correspond to the buccolingual diameter of the upper canine and both second molars; in these cases, sex differences are statistically significant. The results obtained about sexual dimorphism are located at the upper end of the range for different human populations. Several individuals who had no previous sexual information could be classified using these measurements, which accounts for the significant potential of dental metrics in palaeodemographic characterizations, especially in disturbed bioarchaeological samples.</p><p>Keywords: dental metrics; sexual determination; hunter-gatherers; lower basin of the Colorado River; Late Holocene.</p>
