Population Recovery of Nicobar Long-Tailed Macaque Macaca fascicularis umbrosus following a Tsunami in the Nicobar Islands, India

Natural disasters pose a threat to isolated populations of species with restricted distributions, especially those inhabiting islands. The Nicobar long tailed macaque. Macaca fascicularis umbrosus, is one such species found in the three southernmost islands (viz. Great Nicobar, Little Nicobar and Katchal) of the Andaman and Nicobar archipelago, India. These islands were hit by a massive tsunami (Indian Ocean tsunami, 26 December 2004) after a 9.2 magnitude earthquake. Earlier studies Umapathy et al. 2003; Sivakumar, 2004] reported a sharp decline in the population of M. f. umbrosus after thetsunami. We studied the distribution and population status of M. f. umbrosus on thethree Nicobar Islands and compared our results with those of the previous studies. We carried out trail surveys on existing paths and trails on three islands to get encounter rate as measure of abundance. We also checked the degree of inundation due to tsunami by using Normalized Difference Water Index (NDWI) on landsat imageries of the study area before and after tsunami. Theencounter rate of groups per kilometre of M. f. umbrosus in Great Nicobar, Little Nicobar and Katchal was 0.30, 0.35 and 0.48 respectively with the mean group size of 39 in Great Nicobar and 43 in Katchal following the tsunami. This was higher than that reported in the two earlier studies conducted before and after the tsunami. Post tsunami, there was a significant change in the proportion of adult males, adult females and immatures, but mean group size did not differ as compared to pre tsunami. The results show that population has recovered from a drastic decline caused by tsunami, but it cannot be ascertained whether it has reached stability because of the altered group structure. This study demonstrates the effect of natural disasters on island occurring species.

Archean tectonics and crustal evolution of the Biligiri Rangan Block, southern India

The Southern Granulite Terrain in India is a collage of crustal blocks ranging in age from Archean to Neoproterozoic. This study investigate the tectonic evolution of one of the northernmost block- the Biligiri Block (BRB) through a multidisciplinary approach involving field investigation, petrographic studies, LA-ICPMS zircon U-Pb geochronology, Hf isotopic analyses, metamorphic P-T phase diagram computations, and crustal thickness modeling. The garnet bearing quartzofeldspathic gneiss from the central BRB preserve Mesoarchean magmatic zircons with ages between 3207 and 2806 Ma and positive epsilon Hf value (+2.7) which possibly indicates vestiges of a Mesoarchean primitive continental crust. The occurrence of quartzite-iron formation intercalation as well as ultramafic lenses along the western boundary of the BRB is interpreted to indicate that the Kollegal structural lineament is a possible paleo-suture. Phase diagram computation of a metagabbro from the southwestern periphery of the Kollegal suture zone reveals high-pressure (similar to 18.5 kbar) and medium-temperature (similar to 840 degrees C) metamorphism, likely during eastward subduction of the Western Dharwar oceanic crust beneath the Mesoarchean BRB. In the model presented here, slab subduction, melting and underplating processes generated arc magmatism and subsequent charnockitization within the BRB between ca. 2650 Ma and ca. 2498 Ma. These results thus reveal Meso- to Neoarchean tectonic evolution of the BRB. The spatial variation of crustal thickness, derived from flexure inversion technique, provides additional constraints on the tectonic linkage of the BRB with its surrounding terrains. In conjunction with published data, the Moyar and the Kollegal suture zones are considered to mark the trace of ocean closure along which the Nilgiri and Biligiri Rangan Blocks accreted on to the Western Dharwar Craton.

Microhyla laterite sp nov., A New Species of Microhyla Tschudi, 1838 (Amphibia: Anura: Microhylidae) from a Laterite Rock Formation in South West India

In recent times, several new species of amphibians have been described from India. Many of these discoveries are from biodiversity hotspots or from within protected areas. We undertook amphibian surveys in human dominated landscapes outside of protected areas in south western region of India between years 2013-2015. We encountered a new species of Microhyla which is described here as Microhyla laterite sp. nov. It was delimited using molecular, morphometric and bioacoustics comparisons. Microhyla laterite sp. nov. appears to be restricted to areas of the West coast of India dominated by laterite rock formations. The laterite rock formations date as far back as the Cretaceous-Tertiary boundary and are considered to be wastelands in-spite of their intriguing geological history. We identify knowledge gaps in our understanding of the genus Microhyla from the Indian subcontinent and suggest ways to bridge them.

Assessment of driver vision functions in relation to their crash involvement in India

Among the human factors that influence safe driving, visual skills of the driver can be considered fundamental. This study mainly focuses on investigating the effect of visual functions of drivers in India on their road crash involvement. Experiments were conducted to assess vision functions of Indian licensed drivers belonging to various organizations, age groups and driving experience. The test results were further related to the crash involvement histories of drivers through statistical tools. A generalized linear model was developed to ascertain the influence of these traits on propensity of crash involvement. Among the sampled drivers, colour vision, vertical field of vision, depth perception, contrast sensitivity, acuity and phoria were found to influence their crash involvement rates. In India, there are no efficient standards and testing methods to assess the visual capabilities of drivers during their licensing process and this study highlights the need for the same.

Disaggregation of LST over India: comparative analysis of different vegetation indices

The non-availability of high-spatial-resolution thermal data from satellites on a consistent basis led to the development of different models for sharpening coarse-spatial-resolution thermal data. Thermal sharpening models that are based on the relationship between land-surface temperature (LST) and a vegetation index (VI) such as the normalized difference vegetation index (NDVI) or fraction vegetation cover (FVC) have gained much attention due to their simplicity, physical basis, and operational capability. However, there are hardly any studies in the literature examining comprehensively various VIs apart from NDVI and FVC, which may be better suited for thermal sharpening over agricultural and natural landscapes. The aim of this study is to compare the relative performance of five different VIs, namely NDVI, FVC, the normalized difference water index (NDWI), soil adjusted vegetation index (SAVI), and modified soil adjusted vegetation index (MSAVI), for thermal sharpening using the DisTrad thermal sharpening model over agricultural and natural landscapes in India. Multi-temporal LST data from Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and Moderate Resolution Imaging Spectroradiometer (MODIS) sensors obtained over two different agro-climatic grids in India were disaggregated from 960 m to 120 m spatial resolution. The sharpened LST was compared with the reference LST estimated from the Landsat data at 120 m spatial resolution. In addition to this, MODIS LST was disaggregated from 960 m to 480 m and compared with ground measurements at five sites in India. It was found that NDVI and FVC performed better only under wet conditions, whereas under drier conditions, the performance of NDWI was superior to other indices and produced accurate results. SAVI and MSAVI always produced poorer results compared with NDVI/FVC and NDWI for wet and dry cases, respectively.

Molecular phylogeny of Glyphochloa (Poaceae, Panicoideae), an endemic grass genus from the Western Ghats, India

The genus Glyphochloa (Poaceae: Panicoideae: Andropogoneae: Rottboellinae) is endemic to peninsular India and is distributed on lateritic plateaus of low and high altitude in and around Western Ghats and the Malabar Coast. The genus presumably originated and diversified in the Western Ghats. Species relationships in the genus Glyphochloa were deduced here based on molecular phylogenies inferred using nuclear ribosomal ITS sequences and plastid intergenic spacer regions (atpB-rbcL, trnT-trnL, trnL-trnF), and new observations were made of spikelet morphology, caryopsis morphology and meiotic chromosome counts. We observed two distinct clades of Glyphochloa s.l. One of these (group I') includes Ophiuros bombaiensis, and is characterized by a single-awned lower glume and a base chromosome number of 6; it grows in low elevation coastal areas. The other clade (group II') has a double-awned lower glume, a base chromosome number of 7, and is restricted to higher elevation lateritic plateaus; G. ratnagirica may belong to the group II clade, or may be a third distinct lineage in the genus. A sister-group relationship between group I and II taxa (with or without G. ratnagirica) is not well supported, although the genus is recovered as monophyletic in shortest trees inferred using ITS or concatenated plastid data. We present a key to species of Glyphochloa and make a new combination for O. bombaiensis.

Evaluación de semilla sexual hibrida de papa (Solanum tuberosum L.) provenientes del Centro Internacional de la Papa e India en la zona de Miraflor, Esteli

Con el objetivo de seleccionar progenies promisorias de semilla sexual de papa, procedentes del CIP (11) y Programa de la India (3) se estableció este ensayo el 21 de septiembre de 1994, utilizando un diseño de Bloques Completos al Azar (BCA) con cuatro repeticiones, en la estación experimental del Instituto Nicaragüense de Tecnología Agropecuaria (INTA-RB-3), ubicada a 1 350 msnm, humedad relativa del 91 por ciento, temperatura promedio mínima 15 °C/máx 26 °C, cuyos suelos son de textura franca bien drenada, medianamente profundo a profundo, con una precipitación durante el ensayo de 622 mm. Los resultados obtenidos muestran que todas las progenies híbridas enviadas por el CIP mostraron buena velocidad de emergencia en especial SERRANA x LT-7, con respecto a los lubridos de la India. En general el porcentaje de sobrevivencia fue mayor del 80 por ciento para la mayoría de las progenies el cual es un índice aceptable, a excepción de 104.12 LB x TS-4.En la altura final de la planta no hubieron diferencias significativas entre híbridos, solo fueron superiores a KATADIN x TS-10. En cuanto al rendimiento, la progenie HPS­ II/67 mostró ser superior a las demás con 6.2 kg/m2. El número total de tubérculos por metro cuadrado {740) y tubérculos por planta (7) fue superior en la progenie TS-6 x TPS-67. Las progenies de ambos programas mostraron rendimientos por metro cuadrado de más del 50 por ciento con tubérculos mayores de 5 gramos. No se presentó incidencia de virus para ambas progenies, las tres progenies provenientes del Programa de la India presentaron mayor resistencia a tizón tardío (Phytophthora infestans, Mont. D.bary).

Luego de centrarse en la perspectiva hermenéutica, se detallan las épocas de la tradición clásica de la India y las características básicas de su espiritualidad. La autora se adentra a continuación en cuatro nociones que pueden comprenderse como portales de acceso al mundo Indio: mâyâ, karma, yoga y moksha. A la luz de estas nociones tan específicas, la conclusión plantea el diálogo entre disciplinas y culturas como vía para comprender la profunda interdependencia del mundo.

Arreglos de siembra y fertilización orgánica sobre el crecimiento del cedro rosado de la India (Acrocarpus fraxinifolius) en una plantación de dos años en la comarca Las Mercedes, Boaco

La situación actual de algunos productores del país es crítica debido al avance de la frontera agrícola y a los bajos rendimientos de sus cultivos, que trae como consecuencia una deforestación indiscriminada de los recursos forestales. Como alternativa ante esta problemática surge el Cedro Rosado de la India ( Acrocarpus fraxinifolius ), una especie forestal que puede contribuir a la reforestación y al aprovechamiento sostenible de la explotación maderera. Por tanto, el presente estudio procura aportar información sobre esta especie al evaluar dos densidades de siembra (400 y 625 plantas por hectárea) y cuatro niveles de lombrihumus (0.5, 1.0, 1.5 y 2.0 kilogramos por planta) sobre el crecimiento de A. fraxinifolius de dos años de desarrollo. El estudio se desarrolló a partir de febrero del 2005 en la finca La Cañada, comarca Las Mercedes, departamento de Boaco. Las unidades experimentales muestreadas en los lotes con densidades de siembra establecidas fueron agrupadas en tres bloques y la fertilización fue aplicada en parcelas dentro de cada densidad de siembra, lo que correspondió a un arreglo de parcelas divididas, en las que se evaluaron las variables de crecimiento. Se realizó análisis de varianza (ANDEVA) y agrupaciones mediante LSD (∞=0.05). Las variables no tuvieron significación estadística en las densidades de siembra; pero sí en la fertilización. Se obtuvieron 7.224 m en altura de planta, 4.584 m en altura del fuste comercial, 0.11 m en el diámetro a la altura del pecho, 0.33 m en el perímetro a la altura del pecho, 35.09 unidades de ramas, 0.0085 m 2 de área basal y 0.0422 m 3 de volumen. Los factores estudiados resultaron ser independiente. Los mayores valores en variables se alcanzaron con las dosis de lombrihumus y densidad poblacional más alta. La densidad de 625 plantas por hectáreas y 1.5 y 2.0 kilogramos por planta superaron los 30 m 3 de madera. Así mismo, el mayor beneficio costo se obtuvo con la densidad de 625 y 0.5 kilogramos de lombrihumus por planta, con una ganancia de 50.27 por cada dólar invertido.

Expanding adoption of drinking water treatment systems in developing countries: a case study from Tamil Nadu, India

Household-level water treatment and safe storage systems (HWTS) are simple, local, user-friendly, and low cost options to improve drinking water quality at the point of use. However, despite conclusive evidence of the health and economic benefits of HWTS, and promotion efforts in over 50 countries in the past 20 years, implementation outcomes have been slow, reaching only 5-10 million regular users. This study attempts to understand the barriers and drivers affecting HWTS implementation. Using a case study example of a biosand filter program in southern India, system dynamics modelling is shown to be a useful tool to map the inter-relationships of different critical factors and to understand the dissemination dynamics. It is found that the co-existence of expanding quickly and achieving financial sustainability appears to be difficult to achieve under the current program structure.

Marine protected areas in India

This study on marine protected areas (MPAs) in India analyzes the legal and institutional framework for their establishment, and uses two case studies – the Gulf of Mannar National Park and Biosphere Reserve, and the Malvan (Marine) Wildlife Sanctuary – to document and understand the experiences and views of local communities, particularly fishing communities, with respect to the various aspects of design and implementation of protected areas. Stressing the need for fishing communities to be equal partners in all aspects of MPA design, implementation and monitoring, the study concludes with specific recommendations. (68 pp.)

Decadas da Asia, que tratam dos mares, que descobriram, armadas, que desbaratarão, exercitos, que vencerão, e das acçoens heroicas, e façanhas bellicas, que obrarão os portuguezes nas conquistas do oriente : escritas por Diogo do Couto, cronista e guarda mor da Torre do Tombo do Estado da India

Diogo do Couto nasceu em Lisboa em 1542 e morreu em Goa em 1616. Historiador e guarda-mor do Tombo de Goa. Continuou por ordem de Filipe II as Décadas de João de Barros, escrevendo da quarta à décima segunda. Segundo Inocêncio, as ‘Décadas’ IV, V, Vl, VII e VIII foram todas reimpressas, saindo juntamente com a IX, ou o seu epilogo, que, pela primeira vez então se estampou com o titulo ‘Decadas da Asia, que tratam dos mares’. A edição de 1736 não contém os cinco livros da ‘Década XII’, apesar de já terem sido publicados naquela época
