Abstract Complex microbial communities inhabit vertebrate digestive systems but thorough understanding of the ecological dynamics and functions host-associated microbiota within natural habitats is limited. We investigate role environmental conditions in shaping gut skin under by performing a field survey reciprocal transfer experiments with salamander larvae inhabiting two distinct (ponds streams). show that are habitat-specific, demonstrating factors mediate community structure. Reciprocal...
Climatic conditions changing over time and space shape the evolution of organisms at multiple levels, including temperate lizards in family Lacertidae. Here we reconstruct a dated phylogenetic tree 262 lacertid species based on supermatrix relying novel phylogenomic datasets fossil calibrations. Diversification lacertids was accompanied by an increasing disparity among occupied bioclimatic niches, especially last 10 Ma, during period progressive global cooling. Temperate also underwent...
In the anuran family Dendrobatidae, aposematic species obtain their toxic or unpalatable alkaloids from dietary sources, a process known as sequestering. To understand how toxicity evolved in this family, it is paramount to elucidate pathways of alkaloid processing (absorption, metabolism, and sequestering). Here, we used an exploratory skin gene expression experiment which captive-bred dendrobatids were fed alkaloids. Most these experiments performed with Dendrobates tinctorius, but some...
Abstract Experimental work in the early 20th century showed that background albedo experienced by larvae of fire salamander ( Salamandra salamandra ) induce a durable morphological modification postmetamorphic color pattern, which needed confirmation due to controversies regarding Paul Kammerer's experiments. Such carry‐over effect would be relevant as black and yellow pattern alkaloid‐containing adult salamanders has been suggested serve an aposematic signal. Hence, we hypothesized (a)...
Abstract The postembryonic development of amphibians has been characterized as divided into three predominant periods, hereafter named primary developmental stages: premetamorphosis (PreM), prometamorphosis (ProM), metamorphic climax (Meta), and completion metamorphosis (PostM), largely based on examination anuran development. Here, we categorized the larvae a poisonous fire salamander ( Salamandra salamandra ) by integrating morphology gene expression (transcriptomic) data. Morphological...
The North African fire salamander, Salamandra algira , is distributed in Algeria, Morocco and Ceuta (Spanish territory located on the north coast of Africa), but until now rather limited information has been available populations across Algerian part its range. We here provide a first analysis phylogeography this species based 44 samples from 15 localities Central Algeria. sequenced three segments mitochondrial DNA, covering 12S rRNA, cytochrome b (Cytb) D-loop. mtDNA sequences were strongly...
Phenotypic plasticity and local adaptation via genetic change are two major mechanisms of response to dynamic environmental conditions. These not mutually exclusive, since can establish similar phenotypes plasticity. This connection between both raises the question how much variation observed species or populations is plastic it genetic. In this study, we used a structured population fire salamanders (Salamandra salamandra), in which subpopulations differ terms physiology, genetics, mate-,...
The genus Brachycephalus is a fascinating group of miniaturized anurans from the Brazilian Atlantic Forest, comprising conspicuous, brightly colored pumpkin-toadlets and cryptic flea-toads. Pumpkin-toadlets are known to contain tetrodotoxins therefore, their bright colors may perform an aposematic function. Previous studies based on limited number mitochondrial nuclear-encoded markers supported existence two clades containing species pumpkin-toadlet phenotype, but deep nodes remained largely...
We reconstructed nearly complete mitogenomes for three species of poison frogs, Dendrobates auratus, D. leucomelas, and tinctorius, from RNAseq data. recovered the 13 protein-coding genes, 22 tRNA genes (except tRNA-Val leucomelas), two rRNA all species, plus partial sequences control region. The order agrees with that known a previously sequenced being most commonly found neobatrachian frogs. Based on full-sibling comparisons we estimate probable error rate Illumina-RNAseq up to 0.15%.

Abstract Animals show a spectrum of avoidance-tolerance to foods containing toxic secondary metabolites. However, this has not been evaluated in animals that may actively seek out these compounds as chemical defense. Poison frogs sequester and unpalatable alkaloids from their diet, some species, tadpoles are exposed toxins before the development skin granular glands, which used for toxin compartmentalization. Here, we examined effects alkaloid decahydroquinoline (DHQ) Mimetic poison frog,...
Proper inverter operation is often only possible with the help of snubber circuits. Snubber design a time consuming task requiring trade-offs between critical circuit parameters. The program DISCO/W calculates standard RC dissipative snubbers and low loss energy recovering (in either single capacitor or three pole configurations) and, using Microsoft Windows 95(R) Graphic User Interface, helps designer in selection best completely interactive way. generates listing components SPICE...
