Dispersal is a central process in ecology and evolution. It strongly influences the dynamics
of spatially structured populations and affects evolutionary processes by shaping patterns of …

Tetrodotoxin (TTX) is a potent neurotoxin that was first identified in pufferfish but has since
been isolated from an array of taxa that host TTX-producing bacteria. However, determining …

Site fidelity, or the behavior of returning to previously visited locations, has been observed
across taxa and ecosystems. By developing familiarity with a particular location, site fidelity …

Covering: 2017–2019 Guanidine natural products isolated from microorganisms, marine
invertebrates and terrestrial plants, amphibians and spiders, represented by non-ribosomal …

Terrestrial salamanders of the genus Salamandra represent one of the most prominent
groups of amphibians. They are mainly distributed across Europe but also reach Northern …

Toxin evolution in animals is one of the most fascinating and complex subjects of scientific
inquiry today. Gaining an understanding of toxins poses a multifaceted challenge given the …

Inducible phenotypic responses to environmental variation are ubiquitous across the tree of
life, but it remains an open question whether amphibian chemical defense phenotypes are …

Introduction Breeding-site fidelity can occur at various spatial scales and can vary in strength
across these scales. Understanding this variation, and rules governing individual site-fidelity …

Urodele amphibians (∼ 768 spp.), salamanders and newts, are a rich source of molecules
with bioactive properties, especially those isolated from their skin secretions. These include …

Lyciasalamandra species, like most amphibians, secrete a wide array of compounds from
their granular and mucous skin glands, including the internally synthesized samandarine …
