Gut feeling: host and habitat as drivers of the microbiome in blackbuck (Antilope cervicapra)

This study identifies intrinsic and extrinsic factors shaping the gut microbiome of blackbuck across their range, finding host genetic diversity more influential than environmental factors.

Don't Leave the Past Behind: How Larval Experience Shapes Pupal Antipredator Response in Aedes aegypti

This study investigates whether predation risk experienced during the larval stage of Aedes aegypti influences antipredator behavior in the subsequent pupal stage.

Dance or disappear: Strategic sexual signalling in Peninsular rock agama

The paper investigates female sexual signaling strategies in a polygynous lizard, finding that females invest more in signaling towards high-quality males and increase signaling later in the breeding season.

Leadership and information transfer in groups escaping a (simulated) threat in the wild

The paper studies how blackbuck groups respond to a simulated threat, finding that leadership emerges during escape and that rear individuals influence group movement.

Assessment of long-term trends in a threatened grassland bird community using daily bird lists

The paper tracks long-term population trends of grassland birds in central India using daily bird lists over 13 years, showing declines in some species and increases in others.

Competing females strategically combine signals and physical aggression differently from males in a polygynous tropical lizard

The paper shows female lizards use complex, threat-sensitive strategies combining signals and aggression, differing from males in a polygynous species.

Antelope space-use and behavioural responses to varying anthropogenic influences may permit long-term persistence in a highly human-dominated landscape

This study examines how blackbuck respond to human and natural risks in a human-dominated landscape, finding they avoid high human activity areas and are influenced by livestock presence and habitat openness.

Trait evolution under multiple selection pressures: Prey responses to predictable and unpredictable variation

The paper examines how prey behavior is shaped by predictable and unpredictable predation risks and other selection pressures, finding that females balance multiple risks when choosing oviposition sites.

Is the predation risk of mate-searching different between the sexes?

The study compares predation risk between male and female tree crickets during mate searching and finds no difference in risk faced by either sex.

Truncated power-law distribution of group sizes in antelope

The paper analyzes group size distributions of blackbuck antelopes and finds the polylog distribution best fits the data, showing how habitat openness influences group dynamics.
