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.

Contrasting parental roles shape sex differences in poison frog space use but not navigational performance

This study examines sex differences in poison frog spatial behavior and finds that parental roles influence space use but not navigational performance, challenging the adaptive specialization hypothesis.

Land use impacts poison frog chemical defenses through changes in leaf litter ant communities

This study links land use changes to poison frog chemical defenses by showing habitat fragmentation alters leaf litter ant communities, which in turn affects frog diet and alkaloid profiles.

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.

Real-time DNA barcoding in a remote rainforest using nanopore sequencing

This study demonstrates real-time DNA barcoding in a remote rainforest using nanopore sequencing to identify species with high accuracy.
