| Since the completion of the Navstar Global Positioning System (GPS) in 1995, the integration of GPS and Geographical Information Systems (GIS) technology has expanded to a great number of ecological and conservation applications. In tropical rain forest ecology, however, the technology has remained relatively neglected, despite its great potential. Notwithstanding cost, this is principally due to (1) the difficulty of quality satellite reception beneath a dense forest canopy, and (2) a degree of spatial error unacceptable to fine-scale vegetation mapping. Here, we report on the technical use of GPS/GIS in the rain forest of Kibale National Park, Uganda, and the methodology necessary to acquire high-accuracy spatial measurements. We conclude that the... |

| O método de levantamento aéreo foi adaptado e utilizado pela primeira vez para a elaboração de mapas de distribuição e quantificação de classes de vegetação no Pantanal Mato-Grossense por sub-região. Foram identificadas 16 classes, baseando-se em aspectos fitofisionômicos, sendo as principais campo (31,1%), cerradão (22,1%), cerrado (14,3%), brejos (7,4%), mata semidecídua (4,0%), mata de galeria e 2,4% de baceiro ou batume. Estas informações podem subsidiar a escolha de áreas de conservação ou preservação, bem como auxiliar o monitoramento de áreas com grande extensão e difícil acesso. |

| Global Positioning System (GPS) satellite navigation receivers are increasingly being used in ecological and behavioural studies to track the movements of animals in relation to the environments in which they live and forage. Concurrent recording of the animal's foraging behaviour (e.g. from jaw movement recording) allows foraging locations to be determined. By combining the animal GPS movement and foraging data with habitat and vegetation maps using a Geographical Information System (GIS) it is possible to relate animal movement and foraging location to landscape and habitat features and vegetation types. This powerful approach is opening up new opportunities to study the spatial aspects of animal behaviour, especially foraging behaviour, with far greater... |
