Spatial and temporal patterns in Lemniscomys striatus (Linnaeus 1758) as revealed by radio-tracking

Lemniscomys striatus was radio-tracked in the Imperata-Cymbopogon grassland of the Queen Elizabeth National Park in Uganda. Home range sizes calculated by Ranges V® using the minimum convex Polygon method (at 95%) in the postburnt grassland were on average 4.8 times larger than those before the fire. An inverse relation between home range size and population density was found. Lemniscomys striatus was diurnal with two activity peaks during daylight, but activity ended only after dusk. Resume On a etudieLemniscomys striatus par radio-tracking dans la prairie aImperata-Cymbopogon du Parc National Queen Elizabeth, en Ouganda. La taille des territoires calculees par Ranges V® en utilisant la methode du polygone convexe minimum (a 95%) dans la prairie apres les feux, etait en moyenne 4,8 fois plus grande que celles d' avant les feux. On a decouvert une relation inverse entre la taille du territoire et la densite de population. Lemniscomys striatus est diurne, avec deux pics d'activite pendant la journee, mais son activite ne cesse qu' apres le crepuscule.
