Forest is a complex system, consisting of distinct forest communities, and status of any forest can be recognized by analysing its vegetation. For vegetation analysis phytosociological analysis is the best approach. The present study was carried out at 8 different sites of Ramgarh region using different phytosociological parameters. The results of this study revealed, on the basis of IVI, that five major vegetation types viz. Pinus roxburghii, Quercus leucotrichophora, mixed broad leaved, Quercus floribunda and Rhododendron arboreum were dominating this region. The distribution of most of the tree species was random and there was no species having good regeneration status at any site of the region. It was also observed that the anthropogenic disturbance is changing the species richness and diversity of the region. Thus, the conservation and management of these sites are important for the sustainability of forests in the region.

Occurrence of Isoetes coromandeliana L.f. in natural ponds of Harni, Savali and Tuwa (India) is known since 1956 by earlier workers. Equisetum debile Roxb. ex Voucher was also reported in 1962 growing as wild at Savali. Available literature indicates that I. coromandeliana falls under the category of ‘near threatened’ in Asian continents and as an ‘endangered species’ at national (India) level. In the current field work study, the authors could not locate the investigated species from the locations earlier documented by researchers. Few saplings of I. coromandeliana were observed at Talod and Vaktapur near Gandhinagar, a new location for the species. In contrast, E. debile appeared to be lost in wild from Gujarat. Their extinction from earlier reported locations is associated with anthropogenic pressure and thus legal action for their protection is needed. The present paper suggests further survey and habitat based studies and recommends conservation and management action plans based upon the ecology of the habitat.

Understanding how birds use vegetation to obtain food resources has implications for habitat conservation and management. Restinga is a poorly known and threatened tropical habitat, associated to the Atlantic forest, that could benefit from this kind of information to know which plants can be used and dispersed by birds that can help on the maintenance of this habitat. Frugivorous and insectivorous birds are important components of tropical ecosystems, such as restinga. To provide more information regarding the ecology of restinga, we studied the feeding behavior and spatial use of this vegetation by birds at Restinga de Jurubatiba National Park, southeastern Brazil. We found that feeding behavior was similar to that recorded for the same species in other vegetation types. In addition, spatial use of the restinga vegetation by the most abundant species did not overlap greatly, except for two insectivorous species that used different foraging maneuvers and two frugivorous birds that foraged in flocks. The two most abundant species were generalists in their diet and were capable of feeding at the ground level on sand substrate.

Lake Fertilization

Abstract Intensive and expansive human activity greatly accelerates the natural process of lake evolution. It is assumed that an increase in the rate of lake fertilization (often termed “eutrophication”) is the most common and most serious anthropogenic disturbance occurring in these aquatic geoecosystems. Lobelia lakes, one of the most valuable water bodies, are particularly exposed to this type of pressure. The article presents the trophic state of 13 lobelia lakes, located close to the Tricity area, in the northeastern part of the Kashubian Lakeland, which are not legally protected. These lakes represent different geoecosystems determining the rate of their natural evolution, and are subjected to various forms of anthropopressure (numerous summerhouses, fishing, waterside leisure and recreation). The trophic status of these lakes was assessed on the basis of the Carlson-type indices. The evaluation indicated that six of these lakes were in borderline mesotrophic-eutrophic state, and seven represented a significantly advanced eutrophic state.

And Storage

In this paper, growth and storage of carbon and nitrogen in seedlings of banj oak (Quercus leucotrichophora A. Camus) and chir pine (Pinus roxburghii Sarg.) have been compared across different levels of nutrient and water availabilities. Four nutrient (144, 264, 384 and 504 mg of NPK fertilizer per kg soil) and three watering (21 days,14 days and 7 days interval) treatments were applied to seedlings. At low watering levels, seedling dry mass of both the species decreased towards higher nutrient level. However, at high watering level, dry mass increased with increasing water availability. When water availability was increased in a constant nutrient environment, dry mass of seedling increased with increase in water availability. Both the species showed a similar pattern of storing nitrogen instead of increasing biomass particularly at low watering levels. However, at each nutrient level, growth and storage increased with increasing moisture availability. As compared to Q. leucotrichophora, seedlings of P. roxburghii favoured growth over storage (according to its more competitive strategy), although this species accumulated more carbon and nitrogen towards the higher nutrient level.

Macrobenthic community being used as marine health indictor vis-à-vis to anthropogenic disturbance since their characteristic of life cycle (reproductive mode, sedentary, energy transfer, sensitive-resistance species, indicator organism etc.). Therefore, the present study was chosen in Vizag port waters have been subject to a variety of anthropogenic pressure in the last two decades. The purpose of this study was to assess the ecological status of the port environment through biotic indices like AZTI 's Marine Biotic Index (AMBI) and Multivariate-AMBI Index (M-AMBI) which have been successfully validated geographically and anthropogenically stressed habitats. The result revealed that the inner harbor (IHC, Iron ore Q1 & Iron ore Q7) stations are heavily disturbed while the outer harbor fall between undisturbed and moderately disturbed status. It was observed that the reduced tidal action inside the harbor determines the health status indicating that the Iron ore transporting areas are at high risk with respect to benthic population.

The Middle Miocene plant record from the wider Central Paratethys region (Central Paratethys, the North Alpine Foredeep, Carpathian Foredeep, the Swabian Alb and southern parts of the Bohemian Massif) was analysed by the Integrated Plant Record (IPR) vegetation analysis to assess major vegetation types. The plant assemblages at 27 sites accumulated under very different sedimentological settings and refl ect heterogeneous environments. Although of very different origin, the plant record delivers a fairly consistent signal towards subhumid sclerophyllous forests (ShSF) as the most likely major zonal vegetation unit for the Langhian/Serravallian. Today, such forests develop under seasonal climate with pronounced seasonal changes in precipitation. The fl oristic characteristics are outlined and the record is compared to that of the preceding and the following Miocene periods.

Increasing anthropogenic pressure and dependence on plant products has led to widespread exploitation of natural forest in Uttarakhand Himalaya. The study area was selected on the Southern Boundry of Corbett National Park. The objective of the present study was to understand the regeneration status of important tree species in three different types of forests categorized as Highly Disturbed, Moderately disturbed and Least Disturbed sites. Total tree density was higher for least disturbed forest and lower for highly disturbed forest. The regeneration was poor in highly disturbed site compared to least disturbed site. Mallotus philippinensis was germinating and growing as a dominant under canopy tree species across all the sites except least disturbed sites. Sal (Shorea robusta) regeneration was found to be a serious problem. Mallotus philippinensis, Aegle marmelos and Lagerstroemia parviflora showed their dominance across all the sites proving broad ecological amplitude and high tolerance against grazing pressure. At highly disturbed site, species like Mallotus philippinensis, Diospyros tomentosa and Lagerstromeia parviflora were regenerating fairly well with seedlings and saplings but the number of saplings were either less than or equal to adults. Vegetational parameters showed that protected areas ( least disturbed areas ) are important for maintaining regeneration and ecosystem.
