  • Striped Caecilian: Limbless Amphibian spotted in Kaziranga’s fauna

    Why in the News?

    • A limbless amphibian, the striped caecilian (Ichthyophis spp), has been newly identified within the 1,307.49 sq. km Kaziranga National Park and Tiger Reserve.
      • Assam’s wildlife officials reported its discovery during a herpetofauna survey.

    Back2Basics: Herpetofauna

    • Herpetofauna refers to a group of reptiles and amphibians collectively.
    • The term combines “herpeto-” from the Greek “herpeton,” meaning “creeping animal,” and “fauna,” referring to the animal species found in a particular region or time.
    • Herpetofauna play essential roles in ecosystems:
      • They act as both predators and prey, help regulate insect populations, and serve as indicators of environmental health.
      • They serve as environmental indicators and play significant roles in pest control.

    About Striped Caecilian

    • The Striped Caecilian (Ichthyophis spp.) is a type of limbless amphibian belonging to the family Ichthyophiidae.
    • Caecilians are often mistaken for snakes or worms due to their elongated, cylindrical bodies and lack of limbs.
    • They are primarily found in tropical regions of Africa, Asia, and the Americas.
    • They usually live underground or in moist soil habitats.

    Key features of the Striped Caecilian include:

    1. They have smooth, cylindrical bodies with a ringed or striped pattern, hence the name “striped.”
    2. Caecilians are predominantly fossorial (burrowing), spending most of their lives underground or in leaf litter. This behaviour makes them elusive and difficult to study.
    3. They are carnivorous, feeding on small invertebrates found in soil and leaf litter.
    4. Their eyesight is generally poor, and they rely on chemoreception (sensing chemicals in the environment) to locate prey.
    5. Caecilians are known for their unique reproductive strategies, which can involve live births or laying eggs. Some species exhibit parental care, with adults guarding eggs or young offspring.

    Significance: Kaziranga’s Biodiversity

    • Kaziranga National Park’s diverse ecosystem, encompassing flood plains, wetlands, grasslands, and hill tracts, provides an ideal habitat for herpetofauna.
    • The park hosts 24 amphibian species, 74 reptile species, and 21 of India’s 29 species of tortoises and freshwater turtles.

  • What are the findings of the 2024 Hindu Kush Himalayas snow update? | Explained

    Why in the news?

    In 2024, the Hindu Kush Himalaya snow update from the International Centre for Integrated Mountain Development (ICIMOD) reported that the Ganga River basin, India’s largest, experienced its lowest recorded snow persistence.

    What does the report by the International Centre for Integrated Mountain Development highlight?

    • Record Low Snow Persistence: The Ganga River basin, along with the Brahmaputra and Indus basins, reached record low snow persistence in 2024.
    • Significant Declines: The Ganga basin recorded its lowest snow persistence in 22 years, 17% below the long-term historical average. The Brahmaputra basin was 14.6% below normal, and the Indus basin fell 23.3% below normal.
    • Broader Impacts: Similar low snow persistence was recorded in the Amu Darya and Helmand river basins, significantly below normal levels.

    How important is snow persistence?

    • Water Supply: Snow persistence, the fraction of time snow is on the ground, is crucial as its melt provides significant water to streams and ecosystems.
    • Runoff Contribution: Snowmelt contributes 23% of the runoff to the HKH region’s 12 major river basins, supporting nearly one-fourth of the world’s population.
    • Regional Significance: The HKH mountains, known as the “water towers of Asia,” are vital for 10 major river systems, including the Ganga, Brahmaputra, and Indus, which are essential freshwater sources for millions.

    How much of a role does climate change play in river basins receiving low levels of snowmelt this year?

    • Weak Western Disturbances: Lower persistence in 2024 was primarily due to weak Western disturbances, which are low-pressure systems bringing rain and snow to the HKH region.
    • Global Warming Effects: Climate change and global warming destabilize weather patterns, exacerbating prolonged La Niña–El Niño conditions, and influencing the arrival and intensity of western disturbances.
    • High Sea-Surface Temperatures: Persistently high sea-surface temperatures in the regions where western disturbances originate disrupt their formation, leading to reduced snowfall.
    •  Changed the weather system: The pattern of high temperatures and altered weather systems explains both the record low snow persistence in 2024 and similar historical records.

    Way forward:

    • Integrated Water Management: Develop comprehensive water management plans that incorporate predictions of reduced snowmelt. This includes optimising reservoir operations, prioritising water allocation, and implementing efficient irrigation practices to mitigate water scarcity risks.
    • Transboundary Collaboration: Foster regional cooperation among countries sharing river basins affected by declining snow persistence. Develop joint strategies for sustainable water management, disaster risk reduction, and climate change adaptation. This includes sharing hydrological data, coordinating emergency responses, and implementing mutual benefit agreements.
    • Reducing Greenhouse Gas Emissions: Strengthen efforts to mitigate climate change by reducing greenhouse gas emissions at local, national, and international levels. Promote renewable energy sources and sustainable practices to curb global warming, thereby stabilising weather patterns crucial for snowfall.

  • Elephants have names for each other: New study

    Why in the News?

    • Recent studies utilizing Artificial Intelligence (AI) tools have revealed that elephants possess unique names used to address each other, placing them among the select animals with this ability.
      • Unlike animals such as parrots and dolphins, elephants do not imitate the calls of those they address, resembling humans in this communicative trait.

    Naming Behavior in Elephants

    • Unlike humans, elephants do not mimic the calls of the addressee, setting their communication apart from other animals.
    • Published in Nature, the study titled ‘African elephants address one another with individually specific name-like calls’ involved researchers from institutions like Colorado State University and Save The Elephants.

    Study Methodology

    • Communication Methods: Contrary to popular belief, elephants predominantly communicate through low-pitched rumbles rather than trumpets, which are primarily emotional expressions.
    • Data Analysis: Researchers analyzed recordings of wild female African savannah elephants and their offspring’s rumbles across various Kenyan national parks spanning from 1986 to 2022.
    • AI Application: Using AI technology, they scrutinized 469 recorded rumbles to detect patterns indicating specific recipients of the communication.
      • Success Rate: The AI model successfully identified the intended elephant recipient in 27.5% of cases, surpassing chance levels.

    Observations

    • Behavioural Observation: To validate their findings, researchers played back recorded rumbles to 17 elephants and noted heightened reactions when elephants heard their ‘names’, indicating recognition of individual names.
    • Unique Communication: Unlike animals that imitate others’ calls, elephants display no evidence of imitation, suggesting a unique communication strategy.

    Significance of the Study

    • Sophisticated Communication: The study underscores elephants’ advanced communication abilities, challenging previous assumptions about their cognitive prowess.
    • Human-Elephant Parallels: It draws parallels between human and elephant communication, fostering greater admiration for elephants and potentially mitigating human-elephant conflicts crucial for conservation efforts.
    • Future Research: Further investigation is warranted to pinpoint the exact location of elephant names within rumbles and explore whether elephants assign names to objects besides individuals.

  • World Crocodile Day 2024: In 50th year of India’s saurian conservation 

    Why in the news?

    The successful Crocodile Conservation Project in Bhitarkanika National Park is escalating the human-crocodile conflicts affecting local communities.

    About the Crocodile Conservation Project

    • Launch and Objective: The Crocodile Conservation Project was launched in 1975 in Bhitarkanika National Park, Odisha. The main objective was to protect the crocodiles’ natural habitat and revive the population through captive breeding due to the low survival rate of hatchlings in nature.
    • Historical Context: Initiated barely three years after the Wild Life (Protection) Act, 1972. The project was launched due to the threat of extinction from indiscriminate killing for commercial purposes and severe habitat loss.
    • Implementation and Success: Centers for breeding and rearing saltwater crocodiles, muggers, and gharials were started in 34 locations across various states in India under the guidance of HR Bustard. The project in Bhitarkanika, started by Sudhakar Kar and HR Bustard, has been the most successful, increasing the population from 95 in 1975 to 1,811 in the latest reptile census.
    • Ongoing Efforts: Sudhakar Kar continues to provide technical expertise and methodology for the annual census of saltwater crocodiles even after retirement. Conservation of crocodiles is described as a lifelong mission by Kar.

    IUCN Status of Crocodiles of India

    • The three crocodiles of India, the Saltwater Crocodile, Mugger Crocodile, and Gharial, are listed as Least Concern, Vulnerable, and Critically Endangered respectively on the IUCN Red List of Threatened Species.

    Bhitarkanika National Park 

    • Bhitarkanika National Park is a 145 km² (56 sq mi) protected area in Odisha, eastern India. It was designated as a national park in 1998 and obtained the status of a Ramsar site in 2002.
    • The park is known for its unique mangrove ecosystem, which is the second largest in India. It is home to a variety of flora and fauna, including the endangered saltwater crocodile, Indian python, king cobra, black ibis, and darters.

    About the Issues Faced by Bhitarkanika

    • Human-Crocodile Conflict: The increasing crocodile population has led to rising human-crocodile conflicts. Sudhakar Kar expressed concern over the conflicts, warning locals to avoid entering rivers, creeks, and waterbodies inhabited by estuarine crocodiles.
    • Impact on Local Communities: Conflicts have led to 50 deaths since 2014. Local villagers have criticized politicians for not addressing the safety issues adequately, affecting political outcomes.
    • Preventive Measures: Forest officials have erected barricades around 120 river ghats in and around Bhitarkanika to prevent crocodile attacks on humans.
    • Political Implications: The human-crocodile conflict has influenced local political dynamics, with villagers expressing dissatisfaction with incumbents over safety concerns related to crocodile attacks.

    Conclusion: Construct and maintain more robust protective barriers around water bodies, such as reinforced barricades and secure river ghats. Additionally, create safe, designated areas for water-related activities to minimize the risk of crocodile attacks.

  • Formula for Flapping Frequency across Flying and Swimming Animals

     

    Why in the news?

    • Researchers at Roskilde University in Denmark discovered a formula that correlates the flapping frequency of winged and swimming animals to their mass and wing/fins size.
      • The formula applies universally across a diverse range of species, from insects to birds, bats, penguins, whales, and even robotic ornithopters.

    Formula for Flapping Frequency

    • The formula was derived from Newton’s second law (F= mass x acceleration) applied to animals flapping wings to stay airborne.
    • Factors considered in the derivation included air density, wing size, and the forces generated by wing movements.

    Research Methodology

    • The researchers derived the formula theoretically from Newton’s second law, relating the force needed to stay airborne or submerged to the wing/fins’ motion, air/water dynamics, and animal mass.
    • They incorporated empirical observations into a constant C to account for specific shape and flight kinematics variations.

    Application and Validity

    • The formula’s validity was tested across various animals:
      • 176 insect data points (e.g., bees, moths, dragonflies)
      • 212 bird data points (from hummingbirds to swans)
      • 25 bat data points

    Formula Extension to Swimming Animals

    • The formula also predicts the frequency of fin/fluke movements in swimming animals.
    • Adjustments are made for water density and buoyancy effects, excluding fish with swim bladders.

    Limitations and Modifications

    • The formula applies well in conditions with high Reynolds numbers (Re), where fluid flow is streamlined.
    • At low Re values, where viscosity dominates, modifications are needed.
    • The equation holds as long as animal density variations do not exceed a factor of ten.

    Insights and Future Research

    • Insights from the formula include understanding flight efficiency and potential evolutionary pathways for winged animals.
    • Future research aims to explore further insights hidden within the C constant, potentially revealing deeper principles governing animal flight and swimming dynamics.
