TL;DR: Bioprospecting of antiproliferative activity in extracts of Rhinella marina and Rhaebo guttatus toads occurring in the Southern Amazon of Mato Grosso, Brazil showed pronounced lethal and discriminating effects on tumor lines, especially those from R. marina, highlighting toad parotoid gland secretions as a promising source for novel lead anticancer chemicals.

TL;DR: By averaging several methods to estimate total richness, this work confirms that over 15,000 tree species are expected to occur in Amazonia and shows that the species abundance distribution of Amazonia is best approximated by a logseries with aggregated individuals, where aggregation increases with rarity.

TL;DR: Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors.

TL;DR: Ants prevent the access to bees and vice versa as the result of different ability of resource utilization and foraging strategies, which could increase the level of nectar available to pollinators of S. jambolanum, thereby increasing productivity and reducing economic losses.

TL;DR: The HPLC-DAD method was successfully applied to quantify the bufadienolides in the venom extract of the cane toad, which showed a content of 60% of marinobufagin, requiring the development of a technique that presents a greater selectivity.
