Behavioural consistency across metamorphosis in a neotropical poison frog
Animals often show consistency in their behavioural repertoire across time and/or contexts that differs from other individuals of the same...
-
Individual behavioral variability across time and contexts in Dendrobates tinctorius poison frogs
Consistent individual differences in behavior (“animal personality”) have consequences for individual fitness, evolutionary trajectories, and...

The molecular basis and evolution of toxin resistance in poison frogs
Many animals bear conspicuous warning signals that advertise toxin-mediated unpalatability to predators; this is known as aposematism. Frogs in...
-
Experimental evidence in a poison frog model suggests that tadpole transport on the dorsum may affects warning signal effectiveness in poison frogs
Aposematism is an anti-predator strategy where predators learn to associate the warning signal on prey with an unpleasant experience, and...

Developments in the study of poison frog evolutionary ecology I: social interactions, life history and habitat use across space and ontogeny
Poison frogs of the superfamily Dendrobatoidea have fascinated researchers since the 19th century, which is reflected in multiple studies on their...

The ability to sequester the alkaloid epibatidine is widespread among dendrobatid poison frogs
Dendrobatid poison frogs sequester alkaloids from an arthropod diet and use them in chemical defense. Alkaloid defenses vary considerably within and...

Mother strawberry poison frogs might supplement nutritive eggs with secretory provisioning
Many animal lineages produce and provision offspring with nutritive material such as milk, lipid-enriched skin, or mucus. Some frogs deposit...

Under pressure: evidence for selection on color-related genes in poison frogs of the genus Ranitomeya
Aposematic organisms rely on their bright conspicuous coloration to communicate to potential predators that they are toxic and unpalatable. These...

Hormetic action of cyanide: plant gasotransmitter and poison
Hydrogen cyanide (HCN) occurs in living organisms and in the environment. This is a widely known poison but is also considered as a gasotransmitter....

Poison frog social behaviour under global change: potential impacts and future challenges
The current and cascading effects of global change challenges the interactions both between animal individuals (i.e. social and sexual behaviour) and...

Intraspecific divergence of sexual size dimorphism and reproductive strategies in a polytypic poison frog
Intraspecific variation in body size, both among populations and between sexes, is an important factor influencing life-history strategies. This...

Little evidence for color- or size-based mating preferences by male strawberry poison frogs (Oophaga pumilio)
AbstractWhile there are many studies documenting female mating preferences across taxa, male mate choice remains relatively understudied. Male mate...

Home range and notes about social interactions in the poison frog Phyllobates vittatus (Anura: Dendrobatidae)
Understanding animal movements is vital for gaining insights into species' ecological patterns, habitat preferences, and reproductive strategies....

Orientation by environmental geometry and feature cues in the green and black poison frog (Dendrobates auratus)
The ability to use environmental geometry when orienting in space reflects an animal’s ability to use a global, allocentric framework. Therefore,...
-
A potential cost of evolving epibatidine resistance in poison frogs
BackgroundSome dendrobatid poison frogs sequester the toxin epibatidine as a defense against predators. We previously identified an amino acid...

Quantity discrimination in a spontaneous task in a poison frog
The use of quantitative information underlies a range of animal behaviors. There are thought to be two parallel systems for judging quantity: a...

Exploring links between personality traits and their social and non-social environments in wild poison frogs
AbstractAn animal’s behavioral phenotype comprises several traits, which are hierarchically structured in functional units. This is manifested in...
-
Experimental evidence that toe-tap** behavior in the green-and-black poison frog (Dendrobates auratus) is related to prey detection
Toe-tap**, the quick movement of the middle toes of the hind legs, has been observed in many frogs and toads, and is usually associated with...

Identification of the NA+/K+-ATPase α-Isoforms in Six Species of Poison Dart Frogs and their Sensitivity to Cardiotonic Steroids
Cardiotonic steroids (CTS) are a group of compounds known to be toxic due to their ability to inhibit the Na + /K + -ATPase (NKA), which is essential to...

Adult poison frogs can capture and consume aquatic tadpoles
Cannibalism is common in animals, and its expression is shaped by a suite of costs and benefits beyond the caloric content of meals made of...
