Study Notes
Ramdeo Misra
- Recognised as the Father of Ecology in India
- Born August 26, 1908
- Obtained Ph.D in Ecology (1937) from Leeds University, UK
- Established teaching and research in ecology at Banaras Hindu University, Varanasi
- Research focused on tropical communities, plant succession, environmental responses, and nutrient cycling in tropical forests and grasslands
- Formulated the first postgraduate ecology course in India
- Supervised over 50 scholars who went on to establish ecology programs at other universities and research institutions, initiating ecology programs across India.
- Died in 1998
Ramdeo Misra's Contributions
- Laid the foundation for understanding tropical communities and their succession
- Research included environmental responses of plant populations and productivity, nutrient cycling in ecosystems
- Formulated the first postgraduate course in ecology in India
- Mentored over 50 scholars, enabling them to establish ecology programs at other universities
- His efforts led to the establishment of the National Committee for Environmental Planning and Coordination (1972), paving the way for the Ministry of Environment and Forests (1984)
- Directly contributed to the establishment of the Ministry of Environment and Forests (1984)

- Played a key role in establishing the National Committee for Environmental Planning and Coordination (1972), which was a forerunner to the Ministry of Environment and Forests (1984)
- His efforts directly led to the establishment of the Ministry of Environment and Forests (1984)
Organisms and Populations
- Living world is diverse and complex.
- Questions about natural processes can be asked in two ways: 'how' (mechanism) and 'why' (significance).
- Biological levels include macromolecules, cells, tissues, organs, individual organisms, populations, communities, ecosystems, and biomes
- Each level requires both mechanistic and significance questions.
- Understanding biological processes at various levels (cells, tissues, organs, individuals, populations) is key to comprehending complex biological systems.
Population Attributes
- Individuals in groups rarely exist as single entities (shared resources are vital)
- Well-defined geographical areas
- Members of similar species are capable of interbreeding
- A population includes any assemblage of individuals that potentially interbreed regardless of sexual or asexual reproduction, including individuals like bacteria in a culture dish.
- Birth rates, Death rates, Sex ratio, Age distribution (age pyramid), density are factors influencing population size.
- Birth and death rates are per capita changes in numbers divided by population size (e.g., births per individual per year).
- Reproduction is a crucial factor in determining population size.
- Population attributes include birth/death rates, sex ratio, and age distributions (age pyramids) reflective of growth, stability, or decline. Birth rate includes the number of offspring per existing member of the population, and death rate includes the number of deaths per member in the population. -Sex ratios compare the proportion of males to females. -Age distributions or age pyramids can be used to examine if a population is growing, stable, or declining. This information can be displayed graphically. -Individuals can belong to multiple populations depending on location.
Population Growth
- Population size varies over time.
- Driven by births, deaths, immigration, and emigration, with rates calculated within a study period.
- Exponential growth occurs when resources are unlimited, and graphs as a J-shaped curve.
- Logistic growth exhibits a sigmoid pattern, with a stable size (carrying capacity, K) as resources become limited.
- Carrying capacity (K) signifies the maximum sustainable population size in a specific environment.
Factors influencing population growth
- Natality: Number of births per individual
- Mortality: Number of deaths per individual
- Immigration: Individuals entering an area
- Emigration: Individuals leaving an area
- Intrinsic rate of natural increase (r): Potential for population growth in a given period.
- Carrying capacity (K): Maximum size a given environment can sustain.
- Factors influencing population growth include natality (birth), mortality (death), immigration (movement in), and emigration (movement out).
- Density depends on birth/death rates, resources, and predator/prey interactions.
- Population size may be measured in numbers, biomass, or percentage cover by evaluating organisms in a population.
- Population density includes indicators like pug marks and fecal pellets for some species.
- Population density is influenced by birth/death rates, resource availability, and competition.
- Population growth is affected by factors like limited resources, which can result in logistic rather than exponential growth patterns.
- Populations can reach enormous densities in a short time under unlimited resources.
Population Interactions
- Different species may have mutualistic, competitive, parasitic, and commensal relationships
- Interspecific interactions (between species) can be beneficial, detrimental, or neutral
- Predation, parasitism, and commensalism involve close interactions
- Competition may occur between related species or less related or even between different species as competition is not always between similar species; competition can also occur even when resources are abundant.
