| La dispersion des poissons de récifs dépend pour une large part, de l‟existence de larves pélagiques qui peuvent être transportées au sein des courants marins loin de la population source (Cowen et coll., 2000). Ceci est mis clairement en évidence chez les espèces territoriales, celles ayant un mode de vie benthiques ou celles ayant une phase adulte avec de faibles capacités de dispersion. De l‟efficacité de ce transport dépendra donc l‟existence de populations formant un continuum, plus ou moins connectées, tout le long des zones de récifs. Toutefois, ce phénomène de dispersion est beaucoup plus complexe et implique d‟autres facteurs comme le comportement larvaire, la durée du stade larvaire pélagique, sa distribution vertical. D‟autre... |

| The aiming of this review is to point out some research fields in fire ecology and its impact on Amazonia vegetation. The incidence of fire on the moist Amazon region sounded a contradiction until recent years. Fire always acted in vegetation structuring, even though independent of human existence. However, fire regimes are changing worldwide, as in the Amazon, motivated by global climate change and climate anomalies. Forest fires impact vegetation differently, depending on the ecosystem, soil type, and plant morphology and age. Many species can respond positively, with survival mechanisms or post-fire re-growth. A better understanding of how Amazon plants respond to fire impact is necessary in order to understand if... |
