Playback-aided surveys and acoustic monitoring in the detection of the Endangered Forest Owlet Athene blewitti

The paper evaluates playback-aided surveys and acoustic monitoring to detect the Forest Owlet in the Dang region, finding increased detections with new techniques but uncertainty about population trends.

Song Richness Index: A measure to understand the diversity and repetition of notes in a birdsong

The paper introduces the Song Richness Index (SRI) to measure birdsong diversity and compares it to existing measures, finding it more effective for repetitive notes.

Demographic changes of a tropical understory bird in naturally patchy montane habitats in southern India

This study examines how patch size and disturbance affect demographic parameters of a threatened understory bird in the Western Ghats, finding that survival decreases with disturbance but not patch size.

Testing the efficacy of hyperspectral (AVIRIS-NG), multispectral (Sentinel-2) and radar (Sentinel-1) remote sensing images to detect native and invasive non-native trees

This paper evaluates remote sensing data and machine learning algorithms to detect native and invasive tree species in tropical grasslands, finding that hyperspectral data with SVM achieve the highest accuracy.

Spectrogram cross-correlation can be used to measure the complexity of bird vocalizations

This paper introduces a new method, Note Variability Index (NVI), to quantify bird song complexity using spectral cross-correlation, outperforming conventional methods in capturing note variability.

Local extinction of a montane, endemic grassland bird driven by landscape change across its global distribution

The paper examines how habitat features affect the Nilgiri pipit's distribution and abundance, finding elevation and patch size positively influence presence while invasive vegetation negatively impacts abundance.
