    Experiment Design to Assess the Impact of Landscape Structure on Owl Call Activity and Species Richness

    This experiment aims to evaluate how landscape structure, particularly urban representativeness, influences owl call activity and species richness. The study will be conducted in two main areas: semi-urban and rural landscapes. The methodology includes the following steps:

    1. Site Selection

    • Identify Locations: Select multiple sites within semi-urban and rural areas. Ensure that sites vary in urbanization levels, such as proximity to urban centers, density of buildings, and availability of green spaces.
    • Criteria for Selection: Choose sites based on habitat quality, accessibility, and previous records of owl presence. Aim for at least 5 sites in each category (semi-urban and rural).

    2. Acoustic Sensor Deployment

    • Sensor Setup: Deploy 30 acoustic sensors (e.g., Song Meter SM2) across the selected sites. Distribute sensors evenly to cover different habitat types and ensure adequate spatial coverage.
    • Monitoring Period: Conduct monitoring over multiple seasons (e.g., spring and autumn) to capture variations in owl activity related to breeding and migration.

    3. Data Collection

    • Acoustic Monitoring: Record owl calls continuously during the monitoring period. Use automated detection software to analyze call frequency and identify species.
    • Species Richness Assessment: Conduct periodic surveys to identify and record owl species present at each site. This can include visual observations and playback methods to elicit responses from owls.

    4. Data Analysis

    • Acoustic Data Analysis: Analyze the recorded calls to determine call rates and species diversity. Use statistical models to correlate call activity with landscape features (e.g., urban density, green space).
    • Species Richness Analysis: Calculate species richness indices for each site and compare between semi-urban and rural areas. Use diversity indices (e.g., Shannon-Wiener) to assess community composition.

    5. Interpretation of Results

    • Hypothesis Testing: Test the hypothesis that increased urbanization negatively impacts owl call activity and species richness. Use regression analyses to identify significant predictors of owl presence and activity.
    • Ecological Implications: Discuss the implications of findings for urban planning and conservation strategies aimed at preserving owl populations in urbanizing landscapes.

    6. Literature Support

    Relevant studies indicate that urbanization can significantly affect owl populations and their vocal behavior. For instance, research has shown that urban features negatively correlate with bird richness and abundance, suggesting that similar patterns may exist for owls ().

    Additionally, the use of acoustic monitoring has been validated as a cost-effective method for estimating bird populations, which can be applied to owls as well ().

    Acoustic Data Analysis for Owl Monitoring

    This notebook will guide you through the analysis of acoustic data collected from the deployed sensors.


    import pandas as pd
    import numpy as np
    import matplotlib.pyplot as plt
    
    # Load acoustic data
    acoustic_data = pd.read_csv('acoustic_data.csv')
    
    # Analyze call frequency
    call_frequency = acoustic_data.groupby('species')['call_count'].mean()
    call_frequency.plot(kind='bar')
    plt.title('Average Call Frequency by Species')
    plt.xlabel('Species')
    plt.ylabel('Average Call Count')
    plt.show()
    

    Summary of Findings

    This section will summarize the results of the acoustic analysis and discuss implications for owl conservation.

     Hypothesis Graveyard



    The presence of owls is solely determined by food availability, ignoring the impact of urbanization on habitat structure.


    All owl species respond similarly to urbanization, disregarding species-specific adaptations.
