Article
Full-text available
Amphibians are increasingly threatened worldwide, but the availability of genomic resources that could be crucial for implementing informed conservation practices lags well behind that for other vertebrate groups. Here, we describe draft de novo genome, mitogenome and transcriptome assemblies for the Neotropical leaf-frog Phyllomedusa bahiana nativ...
Article
Full-text available
In many vertebrates, the enzymatic oxidation of dietary yellow carotenoids generates red keto‐carotenoids giving color to ornaments. The oxidase CYP2J19 is here a key effector. Its purported intracellular location suggests a shared biochemical pathway between trait expression and cell functioning. This might guarantee the reliability of red colorat...
Article
Red coloration is a salient feature of the natural world. Many vertebrates produce red color by converting dietary yellow carotenoids into red ketocarotenoids via an unknown mechanism. Here, we show that two enzymes, cytochrome P450 2J19 (CYP2J19) and 3-hydroxybutyrate dehydrogenase 1-like (BDH1L), are sufficient to catalyze this conversion. In bir...

Full-text available
Animal coloration is often expressed in periodic patterns that can arise from differential cell migration, yet how these processes are regulated remains elusive. We show that a female-limited polymorphism in dorsal patterning (diamond/chevron) in the brown anole is controlled by a single Mendelian locus. This locus contains the gene CCDC170 that is...
Article
Long‐term maintenance of colour polymorphisms often depends on the interplay of multiple selective forces. In the common wall lizard (Podarcis muralis), up to three pure and two mosaic ventral colour morphs co‐exist across most of its range. Available evidence suggests that colour morphs in this species are maintained through the interaction betwee...

Full-text available
Sexual and social selections promote the evolution of many conspicuous colorations in animals. These traits would act as individual quality signals when they transmit reliable information. Reliability should be assured by production costs unaffordable for low-quality trait bearers or guaranteed if trait expression is tightly linked to individual qu...
Article
The presence of population-specific phenotypes often reflects local adaptation or barriers to gene flow. The co-occurrence of phenotypic polymorphisms that are restricted within the range of a highly mobile species is more difficult to explain. An example of such polymorphisms is in the common quail Coturnix coturnix, a small migratory bird that mo...
Article
Pterins are one of the major sources of bright coloration in animals. They are produced endogenously, participate in vital physiological processes and serve a variety of signalling functions. Despite their ubiquity in nature, pterin-based pigmentation has received little attention when compared to other major pigment classes. Here, we summarize maj...
Article
Full-text available
Color polymorphisms have become a major topic in evolutionary biology and substantial efforts have been devoted to the understanding of the mechanisms responsible for originating such colorful systems. Within-morph continuous variation, on the other hand, has been neglected in most of the studies. Here, we combine spectrophotometric/visual modellin...
Article
The Eurasian Woodcock Scolopax rusticola is a widespread Palearctic migratory wader, with purportedly sedentary populations occurring in the Macaronesian archipelago of the Azores. Here we used microsatellite markers to investigate patterns of genetic diversity and differentiation in these insular birds, and compared Azorean populations to those fr...
Article
Full-text available
Saltatorial locomotion is a type of hopping gait that in mammals can be found in rabbits, hares, kangaroos, and some species of rodents. The molecular mechanisms that control and fine-tune the formation of this type of gait are unknown. Here, we take advantage of one strain of domesticated rabbits, the sauteur d’Alfort, that exhibits an abnormal lo...
Article
Full-text available
Birds exhibit striking variation in eye color that arises from interactions between specialized pigment cells named chromatophores. The types of chromatophores present in the avian iris are lacking from the integument of birds or mammals, but are remarkably similar to those found in the skin of ectothermic vertebrates. To investigate molecular mech...
Article
The study of phenotypic evolution in island birds following colonization is a classic topic in island biogeography. However, few studies explicitly test for the role of selection in shaping trait evolution in these taxa. Here, we studied the Azores woodpigeon (Columba palumbus azorica) to investigate differences between island and mainland populati...
Article
Full-text available
Ornaments can evolve to reveal individual quality when their production/maintenance costs make them reliable as “signals” or if their expression level is intrinsically linked to condition by some unfalsifiable mechanism (“indices”). The latter has been mostly associated with traits constrained by body size. In red ketocarotenoid-based colourations,...
Article
Canaries changing colors Many animals are sexually dimorphic, with different phenotypes in males and females. To identify the genetic basis of sexual differences in bird coloration, Gazda et al. investigated red coloration in mosaic canaries and related species (see the Perspective by Chen). Using a combination of genetic crosses, genomic mapping,...
Technical Report
Full-text available
This report concerns the analysis of the data collected during the 2018/2019 Woodcock (Scolopax rusticola) hunting season in mainland Portugal by the National Association of Woodcock Hunters (Associação Nacional de Caçadores de Galinholas). Woodcock hunting was allowed between November 1, 2018 and February 10, 2019. Thirty-one different hunters pro...

Conspicuous ornaments in animals can evolve to reveal individual quality when their production/maintenance costs make them reliable as signals or if their expression level is intrinsically linked to quality by some unfalsifiable mechanism (quality indices). The latter has been mostly associated with traits constrained by body size. However, red ket...
Article
A first comprehensive account on the dolichopodid fauna (Diptera: Dolichopodidae) of Portugal is presented as the result of multiple surveys by primarily Portuguese researchers between 2009 and 2016. All mainland Portuguese provinces and all districts but one (Évora) were investigated. A total of 761 dolichopodid samples were collected in 278 sampl...

Reptiles use pterin and carotenoid pigments to produce yellow, orange, and red colors. These conspicuous colors serve a diversity of signaling functions, but their molecular basis remains unresolved. Here, we show that the genomes of sympatric color morphs of the European common wall lizard (Podarcis muralis), which differ in orange and yellow pigm...

Article
The Iberian Peninsula harbours an “Endangered” population of the Eurasian Curlew (Numenius arquata), of less than five breeding pairs, restricted to a small geographical area, the Terra Chá district in Lugo (Galicia, Spain). These birds constitute the southernmost breeding nuclei of the species, located 550 km southwest from the nearest nesting sit...
Article
Full-text available
Discrete colour morphs coexisting within a single population are common in nature. In a broad range of organisms, sympatric colour morphs often display major differences in other traits, including morphology, physiology or behaviour. Despite the repeated occurrence of this phenomenon, our understanding of the genetics that underlie multi-trait diff...
Chapter

Four texts for the book chapters on Turdus spp. for the Portuguese wintering and migratory bird atlas.
Article
The consequences of species extinctions in ecological communities may be buffered through the rearrangement (rewiring) of the interactions between the remaining species. The structural and functional consequences of such extinctions can be explored by means of computer simulations that try to predict secondary extinctions and the degradation of eco...
Article
Full-text available
Racing pigeons have been selectively bred to find their way home quickly over what are often extremely long distances. This breed is of substantial commercial value and is also an excellent avian model to gain empirical insights into the evolution of traits associated with flying performance and spatial orientation. Here, we investigate the molecul...
Article
On islands, colonising birds may evolve behavioural and morphological adaptations to the new environment, often resulting in changes in body size and reduction or even total loss of flight. These island populations have therefore been used to test hypotheses related to adaptations for flight. However, in certain species in which flight is used not...
Poster
Morphological trends may vary with the geographic distribution of taxa. Several factors like immigrant selection, ecological release, resource limitation and increased intraspecific competition may be strong selective pressures on island vertebrates. Also, other particular morphological traits related to shifts in ecology (e.g. loss of migratory be...
