Notes of a Case Attacked by an Elephant: Death and Post-Mortem Appearances
scious state, and groaning as if in great pain.

This air-bag bulged and retracted with respiratory movements. A small opening, about ?th ...
متن کاملFire Ants Protect Mealybugs against Their Natural Enemies by Utilizing the Leaf Shelters Constructed by the Leaf Roller Sylepta derogata
The importance of mutualism is receiving more attention in community ecology. In this study, the fire ant Solenopsis invicta was found to take advantage of the shelters constructed by the leaf roller Sylepta derogata to protect mealybugs (Phenacoccus solenopsis) against their natural enemies. This protective effect of fire ant tending on the survival of mealybugs in shelters was observed when e...
متن کاملEvolution of leaf form in marsileaceous ferns: evidence for heterochrony.
Using an explicit phylogenetic framework, ontogenetic patterns of leaf form are compared among the three genera of marsileaceous ferns (Marsilea, Regnellidium, and Pilularia) with the outgroup Asplenium to address the hypothesis that heterochrony played a role in their evolution. We performed a Fourier analysis on a developmental sequence of leaves from individuals of these genera. Principal co...
متن کاملLeaf hydraulic capacity in ferns, conifers and angiosperms: impacts on photosynthetic maxima.
* The hydraulic plumbing of vascular plant leaves varies considerably between major plant groups both in the spatial organization of veins, as well as their anatomical structure. * Five conifers, three ferns and 12 angiosperm trees were selected from tropical and temperate forests to investigate whether the profound differences in foliar morphology of these groups lead to correspondingly profou...
