[source] Long-distance movements of the grey-headed flying fox (Pteropus poliocephalus)JOURNAL OF ZOOLOGY, Issue 2 2004Christopher R. Tidemann Abstract The grey-headed flying fox Pteropus poliocephalus, a nationally vulnerable species, is endemic to coastal eastern Australia, from Maryborough, Queensland, through New South Wales to Melbourne, Victoria. Pteropus poliocephalus forages at night, primarily on eucalypt blossom within 50 km of traditional camps (day roosts), usually in dense, riparian vegetation. Several attempts have been made to track long-distance movements of P. poliocephalus across its extensive and climatically highly variable range, but the technology has been inadequate for tracking at the required speed and scale. Satellite tracking was used to monitor movements of a 2-year-old male P. poliocephalus, trapped at the Currie Park camp in the north of the species' range (28°48,S) from January 2000, and another from its most southerly camp, Melbourne (37°50,S), from April 2000. The first flying fox moved camp 50 km noth-east to Dallas Park, where it stayed until March, then transited at least 15 other camps between 28°12,,32°44,S, before returning to Dallas Park in September. The second flying fox remained in Melbourne until July, then transited at least six other camps to 33°44,S, before returning to Melbourne in January 2001. Both animals made round trips of at least 2000 km, traversing >4° latitude, before returning to their camps of origin, while other animals remained. The study suggests that P. poliocephalus is a partial migrant that uses winds to facilitate long-distance movements, and underlines the importance of management at a national scale.

De Boer The distribution and diet of the elephants of the Maputo Elephant Reserve were studied using dung counts, satellite tracking and faecal analysis. The results were compared with earlier data from before the civil war in Mozambique. The elephant population decreased during the civil war, but 180 animals still remain. Earlier studies described the elephants as preferring the grass plains. Currently, the elephants prefer the dense forest patches over the high quality forage found in the grass plains. Water salinity affected distribution; elephant dung piles were found closer to fresh water in the dry season. A total of 95 different plant species were identified in the faeces. The percentage of grass was relatively low compared with other studies, increasing at the beginning of the rainy season. At the end of the dry season, elephants concentrated on the few available browse species with young leaves, but generally preferred grass species to browse species. Diet composition was mainly affected by season and less by habitat. The elephants have changed their habitat preference in reaction to poaching, and probably increased the contribution of browse species in the diet. The presence of forest patches has been vital for the survival of the elephants. Résumé On a étudié la distribution et le régime alimentaire des éléphants de la Réserve áéléphants de Maputo en utilisant le comptages des crottes, le tracking par satellite et l'analyse des excréments. On a comparé les résultats avec des données recueillies avant la guerre civile au Mozambique. La population d'éléphants a baissé pendant la guerre civile mais il reste 180 animaux. Des études antérieures montraient que les éléphants préféraient les plaines herbeuses. Actuellement, ils préfèrent les ,^lots de forêt dense au fourrage de haute qualité qui se trouve dans les plaines herbeuses. La salinité de l'eau modifie la distribution; on trouvait les crottes d'éléphants plus près de l'eau douce en saison sèche. On a identifié un total de 95 espèces végétales différentes dans les excréments. Le pourcentage d'herbes était relativement bas par rapport aux études antérieures, il augmentait au début de la saison des pluies. A la fin de la saison sèche, les éléphants se concentraient sur les quelques espèces de buissons comestibles ayant des jeunes feuilles, mais ils préféraient généralement les espèces herbeuses aux buissons. La composition du régime était surtout affectée par la saison et moins par l'habitat. Les éléphants ont changé leurs préférences en matière d'habitat en réaction au braconnage et ont sans doute ainsi augmenté la contribution des espèces buissonnantes dans le régime alimentaire. La présence des ,^lots forestiers a été vitale pour la survie des éléphants.
