Even after complete stomatal closure, plants lose water through the leaf cuticles and bark. This residual water conductance of leaves (gleaf-res) and stems (gbark) can negatively impact plant water balance and affect plant survival in seasonally dry environments. However, little is known about the costs and benefits associated with such water leaks, especially on stem level. Here, we characterized the structural and functional determinants of the variability in gbark across tropical savanna species to elucidate...

Drymarchon corais (Colubridae) and Caiman crocodilus (Alligatoridae) use different feeding behaviors to consume poisonous toads

Drymarchon corais and Caiman crocodilus are reported here using different feeding behaviors for consuming poisonous toads of the genus Rhinella (Bufonidae). Drymarchon corais was observed feeding on specimens of Rhinella diptycha without avoiding contact with the parotoid macroglands, suggesting that this snake species is immune to toad toxins. Caiman crocodilus was recorded avoiding contact with the parotoid macroglands of specimens of Rhinella marina by consuming only the front and rear legs, suggesting that this caiman...
