متن کاملVisual mate choice in poison frogs.
We investigated female mate choice on the basis of visual cues in two populations of Dendrobates pumilio, the strawberry poison frog, from the Bocas del Toro Archipelago in Panama, Central America. Mate choice experiments were carried out by presenting subject females of each of two morphs of this species (orange and green) from two different island populations (Nancy Key and Pope Island) with ...
متن کاملPoison Frogs! Targeted Clean-Label Poisoning Attacks on Neural Networks
Data poisoning is a type of adversarial attack on machine learning models wherein the attacker adds examples to the training set to manipulate the behavior of the model at test time. This paper explores a broad class of poisoning attacks on neural nets. The proposed attacks use “clean-labels”; they don’t require the attacker to have any control over the labeling of training data. They are also ...
متن کاملTactical reproductive parasitism via larval cannibalism in Peruvian poison frogs.
We report an unusual example of reproductive parasitism in amphibians. Dendrobates variabilis, an Amazonian poison frog, oviposits at the surface of the water in small pools in plants and deposits tadpoles within the pools. Tadpoles are highly cannibalistic and consume young tadpoles if they are accessible. Deposition of embryos and tadpoles in the same pool is common. Genetic analyses indicate...
متن کاملOribatid mites and skin alkaloids in poison frogs.
A recent publication in Biology Letters added a new family, Eleutherodacytlidae, to the list of frogs known to possess defensive, toxic alkaloids in their skin— the so-called ‘poison frogs’ [1]. The alkaloids have attracted much attention since they are not synthesized by frogs de novo, but rather are obtained from dietary sources and subsequently sequestered in the frogs’ skin [2]. These ‘clep...
