Full textAbstract:
Arbuscular mycorrhizal (AM) fungi are root and soil inhabiting symbionts with higher plants. The fungi are especially nutrient-function efficient in nutrient deficient soils. There have been innumerable studies of AM fungal facilitation of plant nutrient uptake in controlled environments. Comparatively little similar investigation has been undertaken in natural soils, including investigation of taxon specific nutrient-function efficiency in the phylum. Plant diversity and frequency, soil chemistry statuses, and AM spore diversity and abundance were sampled in an interrupted-belt transect in an aggrading dune sytem on west-coast India, followed by foredunes and transect nutrient amendment experiments in selected plant species. The transect extends 175 m inland from mean high-water mark (MH-WM). Examination showed nutrients were consistently deficient. A plant zonation pattern and increasing frequency over the transect were indicated, as well as decreasing pH and increasing organic matter (OM)-amendment AM species diversity gradients. Plant zonation does not correlate with soil chemistry. There was a distinct soil transition at the 175 m point and evidence of further system partition between foredune and behind-foredune regions. Plant and AM demographies bore no resemblance suggesting neither is driven by the other. Four AM genera were recovered, Acaulospora, Gigaspora and Scutellospora in high abundance, Glomus in comparatively low abundance. The two co-dominant species, A. spinosa and Gi. margarita, displayed divergent strategies in OM amendment. Certain AM taxa may be functionally associated with particular soil nutrients. There was no evidence of taxon-specific nutrient-function efficiency.

Full textAbstract:
The Gascoyne continental shelf is located along the north-central coastline of Western Australia between latitudes 21° and 28°S. This study presents CTD and ADCP data together with concurrent wind and satellite imagery, to provide a description of the summer surface circulation pattern along the continental margin, and the hydrography present in the upper 1km of ocean, between latitudes 21° and 35°S. It also discusses the outcome of a numerical modelling study that examined the physical factors contributing to a bifurcation event persistently observed in satellite imagery at Point Cloates. The region comprises a complex system of four surface water types and current systems. The Leeuwin Current dominated the surface flow, transporting lower salinity, warmer water poleward along the shelf-break, and causing downwelling. Its signature ‘aged’ from a warm (24.7°C), lower salinity (34.6) water in the north to a cooler (21.9°C), more saline (35.2) water in the south, as a result of 2-4Sv geostrophic inflow of offshore waters. The structure and strength of the current altered with changing bottom topographies. The Ningaloo Current flowed along the northernmost inner coast of the Gascoyne shelf, carrying upwelled water and re-circulated Leeuwin Current water from the south. Bifurcation of the Ningaloo Current was seen south of the coastal promontory at Point Cloates. Numerical modelling demonstrated a combination of southerly winds and coastal and bottom topography off Point Cloates to be responsible for the recirculation, and indicated that the strength of southerly winds affect recirculation. Hypersaline Shark Bay outflow influenced shelf waters at the Bay’s mouth and to the south of the Bay. The Capes Current, a wind-driven current from south of the study region was identified as a cooler, more saline water mass flowing northward. Results of the hydrography study show five different water masses present in the upper-ocean. Their orientations were affected by the geopotential gradient driven Leeuwin Current/Undercurrent system at the continental margin. The Leeuwin Undercurrent was found at the shelf-slope, carrying (>252 μM/L) Subantarctic Mode Water at a depth of 400m

Morrison, Ann Katherine 1929. "Canadian art and cultural appropriation : Emily Carr and the 1927 exhibition of Canadian West Coast Art - Native and Modern." Thesis, University of British Columbia, 1991. http://hdl.handle.net/2429/31244.
Full textAbstract:
In December 1927, Emily Carr's paintings were shown for the first time in central Canada in an exhibition called Canadian West Coast Art - Native and Modern. This event was held at the National Gallery of Canada in Ottawa, and marked a major turning point in Carr's career, for it brought her acceptance by the intellectual and artistic elite with their powerful networks of influence, as well as national acclaim in the public press. To this point, art historical writings have tended to focus on the artist and her own experiences, and in the process, the importance of this experimental exhibition in which her work was included has been overlooked and marginalized.
This thesis attempts to redress this imbalance by examining the exhibition in detail: first, to analyze the complexities of its ideological premises and the cultural implications of juxtaposing, for the first time in Canada, aboriginal and non-native artistic production within an art gallery setting; second, to consider the roles played by the two curators, Eric Brown, Director of the National Gallery, and C. Marius Barbeau, chief ethnologist at the National Museum; and third, to indicate the ways in which Emily Carr's works and those of the other non-native artists functioned within the exhibition.
During the 1920s, both the National Gallery and the National Museum were caught up in the competitive dynamic of asserting their leadership positions in the cause of Canadian nationalism and the development of a national cultural identity. In this 1927 exhibition, these issues of nationalism, self-definition and the development of a distinctly "Canadian" art permeated its organization and presentation. The appropriated aboriginal cultural material in the museum collections that had languished within storage cases was to be given a contemporary function. It was to be redeemed as "art," specifically as a "primitive" stage in the teleological development of the constructed field of "Canadian" art history. In this elision process, the curators relegated the native culture to a prehistoric and early historic past, suppressing its own parallel historical and cultural development.
The exhibition also presented the native objects as an available source of decorative design motifs to be exploited by non-native artists, designers and industrial firms in their production of Canadian products, underlining the assumption of the right to control and manipulate the culture of the colonized "Other."
Emily Carr"s twenty-six paintings, four hooked rugs and decorated pottery represented the largest contribution from any single artist. In their interpretations of the native culture, Carr and the other non-native artists were also engaged in a "self-other" definition, and had filtered their perceptions through the practices and conventions of western art traditions, especially in the use of modernist techniques. In the context of the exhibition, the artistic production by the fourteen non-native artists, including Carr, was caught up in a reaffirmation of the ideological and cultural positions of the two curators and the institutions they represented. The alternate discourses that could have been provided by the native people remained unheard.Arts, Faculty of

Full textAbstract:
The lerm Cladocera was coined by Latreille (829) and it is
de ri ved from the Greek words Klados (= branch) and Keras (= horn),
afler the two branched second antennae, which are the chief organs of
locomotion in these animals.
An exhaustive r eview of literature concerning the 'Water Fleas'
(cladocerans) has recently been provided by Sharma (991). It would be
redundant to go over the ground once again. Neverthe less, a brief
survey of the history of work on the systematics of Cladocera seems
warranted in this thesis.
In the twelfth edition of the "Syslema Naturae" Linne (1767)
grouped all Branchiopoda known lo him under one genus , Monoculus (=
wilh one eye). But the outline of our present systematical arrangement
was given by Huller (1785), who was the first to subdivide Linne's
Honoculus into several genera: Daphnia, Lynceus and Polyphemus.
Latreille (1817) used Huller's syslem and called the Branchiopoda (=
Entomostraca Huller) the fifth order of lhe Crustacea. In 1829 he
distinguished the Branchiopoda (= gill feet) as the first order within
the Entomostraca; the latter was, in this new edition, the second main

Full textAbstract:
The distribution and abundance of diatoms along the South
west coast of India in relation to the hydrological parameters was
studied by selecting three stations namely, Thalassery, Cochin and
V izhinj am. The present study has been carried out with a view to
study the diatoms of selected areas along the south west coast of
India in relation to the hydrographic factors. Qualitative and
quantitative studies were made along the nearshore and inshore
areas following the standard procedures. Regression analysis was
also conducted to study the various factors contributing the growth
of diatoms along the near shore and inshore areas of the three
selected stations. It was found that the hydrological parameters
showed fluctuation from season to season and within season.
Diatoms along the nearshore areas showed abundance and
dominance during the monsoon season followed by the post
monsoon season, while that along the inshore areas are having the
highest dominance and abundance during post monsoon followed
by monsoon season. The regression analysis indicates that the
diatom population was contributed by different factors at different
stations indicating that they are all independent.

Today, when so much is being said and written about our interests in the ocean, it
is particularly important to retain our perspective. Of course, the present pattern is likely
to change, although how rapidly or dramatically we do not know. What is certain is that
we shall use the ocean more intensively and in a greater variety of ways. Our greatest
need is to use it wisely. The general goal of ecological research to which marine biology
makes an important contribution, is to achieve an understanding and to tum to our
advantage all the biological processes that give our planet its special character. Marine
biology is focussed on the problems of biological production, which are closely related to
problems of production in the economic sense as well. Our most compelling interest is
often narrower. It lies in ocean life as a renewable resource, primarily of protein-rich
foods and food supplements for our domestic animals and to us and of secondary
materials and drugs. At this point, it is time to inquire about the future expectations from
the ocean which is or three dimensional environments provides protein rich seafoods
alternate to agricultural products from land. Other than this, nonliving resources such as
minerals, oil, medicinal properties of the various marine organisms etc. are resources we
collect from the sea.
The present harvest of marine living resources from the world oceans is about 87
million tonnes in 1996 (Anon., 1998). More than 90% of this harvest is finfishes: the rest
consists of whales, crustaceans, molluscs and other invertebrates. It is now a common
knowledge that fish is one of the few major foodstuffs showing an increase in global
production that continues to exceed the growth rate of the human population. This
increase has been accompanied by changing patterns of use. Although some products of
high unit values that includes luxury foods, such as shellfish, have maintained or even
enhanced their relative economic importance and the trend is that moderate catch is used
directly for human consumption and the bulk is reduced to fishmeal for animal feed and
manure. There are also large aggregations of pelagic animals that live further down and
are associated particularly with the "Deep Scattering Layer" (DSL). the sound-reflecting
stratum observed in all oceans which has vast potential to provide exploitable resources.

Full textAbstract:
Globally most of the conventional fish stocks have reached a state of optimum
exploitation or even over-exploitation; efficient utilization of non-conventional resources
is necessary to meet the supply-demand gap for protein supply. Mesopelagic fishes can
be considered as one such promising resource for the future, if appropriate harvest and
post-harvest technologies are developed. Increasing human population and increasing
demand for cheaper food fishes has made myctophids a possible potential resource for
future exploitation and utilization. Earlier studies indicated the abundance of Diaphus
spp. in the eastern and northeastern Arabian Sea. The present study also indicates the
dominance of Diaphus spp. in the deep sea trawling grounds of south west coast of India.

Full textAbstract:
An attempt is made to study the possible relationship between the process of upwelling and zooplankton biomass in the shelf weters along the south west coast of India between Cape comorin and Ratnagiri based on oceanographic and Zooplankton data collected by the erstwhile FAO/UNDP Pelagic Fishery Project,Cochin between 1973 and 1978. Different factors such as the depth from which the bottom waters are induced upwards during the process of upwelling,the depth to which the bottom waters are drawn, vertical velocity of upwelling and the resultant zooplankton productivity were considered while arriving at the deductions. Except for nutrients and phytoplankton productivity, for which simultaneous data is lacking, all the major factors were taken into consideration before cocluding- xon positive/negative correlation.

Full textAbstract:
Bivalves which are filter feeders are found to be the best ones suited
for pollution monitoring because of their abiltiy to concentrate
pollutants to several orders of magnitude. For the present study, black clam,
Villorita cyprilloides was selected owing to its euryhaline and hardy nature.
A fortnightly study conducted at the four stations (station I, 2, 3 &
5) and a seasonal (Pre-monsoon, Monsoon & Post-monsoon) study conducted
at the other four stations (station 4, 6, 7 & 8) revealed a postmonsoon
maxima and a pre-monsoon minima for copper in the whole soft
tissue and digestive gland of clams. Cadmium and lead values were comparatively
low. However, metals in the sediment did not show any seasonal
variation in accumulation. Acute toxicity and bioaccumulation studies
(using copper and lead) showed that copper was more toxic to the clams
than lead. Digestive glands showed highest value for copper whereas gills
showed highest value for lead. A linear relationship between time and
concentration was observed in the accumulation of the two metals in the
tissues studied. Histology of the digestive glands and gills of copper and
lead exposed clams showed severe degeneration and destruction of the
epithelial cells. The planimetric study conducted also revealed destruction of
epithelial cells which was indicated by a significantly lower MET(Mean
Epithelial Thickness) values for copper exposed clams. There was
Significant incrcasc in MLR & MLRlMET values of copper exposed clams.
Though samc results were obtained for lead exposed clams the values did
not show any statistical difference. Fine structure of the digestive glands
of copper and lead exposed clams revealed proliferation of SER, Iysomes,
destruction of digestive cells, a labile nuclear membrane and breakage at
the basal lamina.

Full textAbstract:
Fishes have always been an important source of food for mankind.
Naturally, man is much concerned with not only its exploitation but also
its various research aspects such as taxonomy, biology, fishery, aquaculture
and even genetics. Taxonomically, the unit of fishery resources is the species,
a concept developed during the classical periods of Linnaeus, Lamark and
Darwin. The species concept still remains as the corner stone of scientific
research in various aspects of biology. Nevertheless, according to the Darwin's
theory of origin of species and modern theories of evolution, the species
cannot remain as a constant entity. Each species may undergo further evolutionary
changes leading to further speciation. The process and order of
such further speciation is primarily by reproductive isolation and transform ation
of its populations into different races or sub-species and la ter into new species
in an unspecified evolutionary time scale.

Full textAbstract:
This thesis investigates the efforts of the West Indian Church to establish and run a fascinating Mission in an area of West Africa already influenced by Islam or traditional religion. It focuses mainly on the Pongas Mission’s efforts to spread the Gospel but also discusses its missionary hierarchy during the formative years in the Pongas Country between 1855 and 1863, and the period between 1863 and 1873, when efforts were made to consolidate the Mission under black control and supervision. Between 1873 and 1900 when more Sierra Leonean assistants were hired, relations between them and African-descended West Indian missionaries, as well as between these missionaries and their Eurafrican host chiefs, deteriorated. More efforts were made to consolidate the Pongas Mission amidst greater financial difficulties and increased French influence and restrictive measures against it between 1860 and 1935. These followed an earlier prejudiced policy in the mission that was strongly influenced by the hierarchical nature of nineteenth-century Barbadian society, which was abandoned only after successive deaths and resignations of white superintendents and the demonstrated ability of black pastors to independently run the Mission.
Instrumentalism aided the conversion process and the increased flow of converts threatened both the traditional belief systems and social order of the Pongas Country, resulting in confrontation between the Mission and traditional religion worshippers, while the lack of more legitimate trade in the Pongas Country and allegations of black missionaries’ illicit sexual relations and illegal trading caused the downfall of John Henry A. Duport, the Mission’s first black Head Missionary.
In the late 1800s, efforts to establish a self-supporting, self-generating, and self-propagating church together with initiatives toward African agency in the Pongas Country failed. However, it was French activities and eventual consolidation of their interests in the Pongas Country from 1890 and their demand that Mission schools teach in French, together with successful recruiting of Mission students by the Roman Catholics and Muslim clerics in Guinea, that finally crippled it. Thus, by 1935 when the Gambia-Pongas Bishopric was established in the hope of rescuing the Mission, this gender-biased Christian enterprise in West Africa was already a spent force.

The oceanic environment is the biggest biome on earth and its biota plays a
significant role in global, biological and chemical cycles. (Lawrence and Katherine,
1995). Most of the world's oceans with the exception of the Arctic and Antarctic and
possibly parts of the Central Pacific have a region at depth that reflects or scatters
sound. This is known as the Deep scattering layer (DSL). The Deep scattering layers
in the oceans were first recognized in 1942. The DSL is a layer of living organisms
ranging from about microscopic zooplankton, shrimps, meso pelagic fishes and
cephalopods that prey on one another. This layer migrates vertically in the water
column depending on light intensity and occurs at depths between 230-800m during
the day and 50-100m depth during night. The DSL is an important ecosystem of the
world oceans and supports a wide assembly of zooplankton, macro and micro nekton.
