TENTS AND HAREMS : APPARENT DEFENCE OF FOLIAGE ROOSTS BY TENT-MAKING BATS

摘要: Palmate umbrella tents used by tent-making bats in Trinidad, West Indies, were observed three species of Neotropical palms, Sabal mauritiiformis, Coccothrinax barbadensis and Mauritia flexuosa. Tents most common palm leaves that have supporting petioles angled at 50–70° above the horizontal. The shape volume is influenced mostly leaf morphology (leaf width leaflet length) age tent. Tent-crowns varied from being heart-shaped S. oval or round C. spade-shaped M. Leaves which constructed often beneath overhanging vegetation, generally free vegetation below, allowing to enter depart without impeded clutter adjacent vegetation.Singles small apparent harem groups two bat species, Artibeus jamaicensis Uroderma bilobatum, captured made mauritiiformis barbadensis. No social organization these other suggests modified into may provide critical defendable resources promote evolution polygyny. This hypothesis based on patchy distribution suitable trees, inappropriateness many as potential resultant architecture provided palmate tents. We suggest an adult male behaviour.
