Canopy dynamics and light climates in a tropical moist deciduous forest in India

ABSTRACT. The canopy dynamics and light climates within a 20 by 60 m quadrat were studied in a disturbed moist deciduous forest near Bombay, India. A map was drawn of individual trees within the quadrat, the taxa were identified, and their phenology was followed from November 1984 to July 1985. The quadrat contained 14 species, the most common being Tectona grandis, Terminalia tomentosa, Butea monosperma, Mitragyne parviflora and Albizia procera. Some individuals were in leaf at all times, more so at the moister east end of the quadrat. In Novem- ber at the end of the rainy season, light measurements documented percentages of total daily photosynthetic photon fluence (PPF) at 10.0% of full sunlight; 44% of this flux was due to sun- flecks whose duration was approximately 17% of the daytime hours. Values for six sites were similar to mid-day measurements along a 40 m transect, and consistent with the 94% canopy cover of the sites, photographed with a fish-eye lens. The March dry season measurements re- vealed a more intense radiation environment (54% of solar PPF), and 59% of the photosyn- thetic photon flux density at mid-day along the transect. Canopy openings were increased to a mean of 59.4%. Light in the understorey in November was spectrally altered, with typical R:FR ratios of 0.30, compared to March values identical to those of sunlight, at 1.10.

Blue Development: Analyzing the Role of the State in the Rise of Aquaculture in India

In this paper, I analyze the processes that transformed aquaculture into a major export industry in India, in order to understand the role aquaculture has as a social and economic development strategy of the Indian state. The discussion employs a political ecology approach as I explore the complex relations between access and control of India’s coastal resources, society, and economy. I argue that many of the forces that initiated the development of aquaculture in India, namely the involvement of the Indian state, continue to shape the industry today. I also discuss how despite widespread social conflict, the shrimp farming industry, in particular, continues to thrive and grow in rural India. My analysis utilizes ethnographic and archival data collected over the course of 9 months of fieldwork in Tamil Nadu, India. Keywords: rural development, aquaculture, India, State, ethnography

Comparative Analysis of State and Non-State Higher Educational Institutions in Terms of their Adaptation to New Societal Conditions in Post-Soviet Russia

The present paper investigates post-Soviet non-state and state higher educational institutions in terms of students’ perceptions of school curriculum, quality of teaching, available educational resources and overall organization in their higher educational institutions.
