    What is Functional Diversity?

      • Functional diversity refers to the ecological roles species perform, rather than just counting the number of species.
    • Examples of spider traits studied:
        • Circadian activity
        • Hunting strata
        • Ballooning ability
        • Hunting guild
        • Prey range
    • Higher functional diversity means:
      • Greater ecological stability
      • Better pest control
      • More resilience against disturbances

    Key Findings

    • Decline with Elevation: Species richness and functional redundancy decrease with altitude, with a critical threshold around 3,000 to 3,500 metres near the Himalayan treeline, increasing ecosystem vulnerability.
    • Agricultural Homogenisation: Functional diversity remains stable across elevations in agricultural areas, indicating trait homogenisation due to intensification, with dominance of ground dwelling spiders like Lycosidae.
    • Forest Elevational Gradients: Forest ecosystems show clear trait shifts with altitude, with communities largely dominated by cathemeral species.
    • Human Dominated Landscapes: Greater trait richness at lower elevations supports the intermediate disturbance hypothesis, with presence of synanthropic species adapted to human environments.

    Ecological Importance of Spiders

    • Among the most voracious arthropod predators.
    • Consume over 600 million tonnes of insects annually.
    • Help regulate pest populations and disease vectors.
    • Act as bioindicators of habitat disturbance.
    [2011] The Himalayan Range is very rich in species diversity. Which one among the following is the most appropriate reason for this phenomenon? (a) It has a high rainfall that supports luxuriant vegetative growth. 

    (b) It is a confluence of different biogeographical zones. 

    (c) Exotic and invasive species have not been introduced in this region. 

    (d) It has less human interference.
