Abstract A study of the activity patterns, time allocation for each activity and variations in activities due to environmental alterations are necessary for understanding the biology of any species. This study investigates the relationship of micro-habitat and environmental conditions with seasonal and temporal activities of Indian crested porcupines (ICP) around their burrows in Keoladeo National Park (KNP), India. This species is considered as a problem species, often ignoring its ecological importance as an ecosystem engineer. Of the 39 sampled burrows, 58.97%, 38.46% and 83.78% were occupied in winter, summer and monsoon, respectively. The estimated porcupine density was 3.21±1.32SD individuals/km2, accounting for a population size of 65.89±27.15SD individuals. A seasonal shift in rate of emergence was observed in monsoon and winter, when ICP emerged earlier, significantly correlating with the sunset timings. The daily activity records of adult ICP outside burrow significantly peaked in January–February when they prepare the burrows for the gestation period of 90–112 days, followed by rearing of the offspring. The temporal activity significantly reduced in the full moon nights, perhaps to avoid predators. The study affirms that environmental determinants including the timings of sunrise, sunset and lunar phase significantly affect the variations in temporal activity and burrow use patterns of ICP.

Burrow Use

Wombats are large, marsupial herbivores able to exploit low-productivity habitats largely because of their low energy requirements. In addition to using deep, thermally favourable burrows, wombats might use a strategy of conservative above-ground ranging behaviour to achieve their low energy expenditure. This study examined home range, burrow use and diurnal activity patterns of common wombats (Vombatus ursinus) in eucalypt forest, woodland and pasture using trapping and radio-tracking. Wombats ranged through all three vegetation types with forest and pasture clearly being important habitats. Home ranges (95% harmonic mean) were typically almost circular, and averaged 17.7 ha with core areas (50% harmonic mean) averaging 2.9 ha. Home-range size is small compared with that expected for most mammals of comparable body mass. Ranging behaviour for wombats was similar between sexes and ranges extensively overlapped between and within sexes, indicating that ranges are not actively defended. Wombats did not markedly change the size or location of home ranges, ranging behaviour or feeding areas between summer and winter. The density of active burrows (0.25 ha–1) far exceeded the estimated density of wombats (0.13 ha–1). Wombats typically spent 1–4 days sleeping in the same burrow and then moved to another. On average, each active burrow was used by 2.2 different individuals. The activity pattern of wombats is characterised by a strong diel cycle, with most activity occurring nocturnally. Activity peaks at the beginning and end of each night are consistent with a ‘travel out, graze, travel back’ movement pattern. Despite widely distributed food resources, small home ranges and obligate burrow use constrain wombats to meeting their year-round food and water requirements from a small area near their burrows.
