Abstract
Sex ratio dynamics in terrestrial isopods are crucial for understanding
their population stability, reproductive strategies and responses to
environmental variability. Studies have shown that sex ratios in isopod
populations often deviate from the expected 1:1, with female-biased ratios
frequently observed, particularly in stable environments, while fluctuations
can occur seasonally or spatially in response to abiotic factors such as
temperature, moisture, and habitat disturbance. Temporal patterns are shown
which include male activity peaking during warmer months followed by increases
in gravid females are indicative of the reproductive cycles and surface
activity patterns linked to mating behaviour. Population density of Philoscia
muscorum was highest during postmonsoon season (71.48±0.2) and lowest
during summer season (12.12±0.3). During monsoon season, population density was
42.92±0.2 and 51.44±0.2 during premonsoon season. Female-biased sex ratios are
found in all seasons under study.
