A toxic environment selects for specialist microbiome in poison frogs

This study shows that alkaloid exposure in poison frogs increases skin microbiome diversity and enables specific microbial adaptations to toxic environments.

Binding and sequestration of poison frog alkaloids by a plasma globulin

The paper identifies a plasma globulin in poison frogs that binds and regulates alkaloid bioavailability, revealing a novel serpin-based mechanism for small molecule transport.

Poison frog chemical defense are influenced by environmental availability and dietary selectivity for ants

This study investigates how environmental availability and dietary selectivity for ants influence chemical defenses in poison frogs.

Definition of a saxitoxin (STX) binding code enables discovery and characterization of the Anuran saxiphilin family

The paper defines the STX binding code for saxiphilin proteins and identifies new members of the Anuran saxiphilin family.

Poison frog dietary preference depends on prey type and alkaloid load

This study investigates poison frog dietary preferences, finding that frogs prefer smaller prey items and that alkaloid load does not significantly alter their preferences.

Molecular physiology of pumiliotoxin sequestration in a poison frog

This study investigates how the Dyeing poison frog metabolizes pumiliotoxin into a more potent alkaloid and identifies gene expression changes and potential metabolic enzymes involved.

Molecular physiology of chemical defenses in a poison frog

The paper investigates how alkaloid sequestration affects gene expression and protein abundance in poison frogs, identifying transport proteins and saxiphilin as potential mediators of toxin accumulation.
