DOI: 10.1007/s10071-021-01528-x
Abstract: The use of quantitative information underlies a range of animal behaviors. There are thought to be two parallel systems for judging quantity: a precise representation of small numbers of objects, typically less than 4, that… read more here.

Sequestered Alkaloid Defenses in the Dendrobatid Poison Frog Oophaga pumilio Provide Variable Protection from Microbial Pathogens

DOI: 10.1007/s10886-018-0930-8
Abstract: Most amphibians produce their own defensive chemicals; however, poison frogs sequester their alkaloid-based defenses from dietary arthropods. Alkaloids function as a defense against predators, and certain types appear to inhibit microbial growth. Alkaloid defenses vary… read more here.

DOI: 10.1016/j.yhbeh.2020.104869
Abstract: Variation in natural behavior is tightly linked to the ecological resources with which they co-evolved. This review discusses poison frog behavior and neuroendocrinology to illustrate how ecological factors drive diversification of behavior and its underlying… read more here.

DOI: 10.1038/s41437-021-00481-2
Abstract: Phenotypic and genetic divergence are shaped by the homogenizing effects of gene flow and the differentiating processes of genetic drift and local adaptation. Herein, we examined the mechanisms that underlie phenotypic (size and color) and… read more here.

DOI: 10.1073/pnas.2218956120
Abstract: The emergence of complex social interactions is predicted to be an important selective force in the diversification of communication systems. Parental care presents a key social context in which to study the evolution of novel… read more here.

DOI: 10.1111/jeb.14111
Abstract: Aposematic species combine a conspicuous signal with a secondary defence, the majority of which are studied in the context of a visual signal. While multimodality of the aposematic signal appears to be common in invertebrate… read more here.

DOI: 10.1186/s12862-019-1410-7
Abstract: BackgroundColor and pattern phenotypes have clear implications for survival and reproduction in many species. However, the mechanisms that produce this coloration are still poorly characterized, especially at the genomic level. Here we have taken a… read more here.

DOI: 10.1242/jeb.230342
Abstract: ABSTRACT Poison frogs sequester chemical defenses from their diet of leaf litter arthropods for defense against predation. Little is known about the physiological adaptations that confer this unusual bioaccumulation ability. We conducted an alkaloid-feeding experiment… read more here.

DOI: 10.1371/journal.pone.0264540
Abstract: Poison frogs bioaccumulate alkaloids for chemical defense from their arthropod diet. Although many alkaloids are accumulated without modification, some poison frog species can metabolize pumiliotoxin (PTX 251D) into the more potent allopumiliotoxin (aPTX 267A). Despite… read more here.

DOI: 10.1371/journal.pone.0276331
Abstract: The ability to acquire chemical defenses through the diet has evolved across several major taxa. Chemically defended organisms may need to balance chemical defense acquisition and nutritional quality of prey items. However, these dietary preferences… read more here.
