Testing for selection is becoming one of the most important steps in analysis multilocus population genetics data sets. Existing applications are difficult to use, leaving many non-trivial, error-prone tasks user. Here we present LOSITAN, a detection workbench based on well evaluated F st -outlier method. LOSITAN greatly facilitates correct approximation model parameters (e.g., genome-wide average, neutral ), provides import and export functions, iterative contour smoothing generation...
Two hypotheses have been proposed to explain the abundance-occupancy relationship (AOR) in parasites. The niche breadth hypothesis suggests that host generalists are more abundant and efficient at colonizing different communities than specialists. trade-off argues specialists achieve high density across their hosts' ranges, whereas incur cost of adaptation diverse immuno-defence systems. We tested these using 386 haemosporidian cytochrome-b lineages (1894 sequences) recovered from 2318 birds...
Significance The yellow, orange, and red colors of birds are produced through the deposition carotenoid pigments into feathers skin, often function as signals in aggressive interactions mate choice. These hypothesized to communicate information about individual quality because their expression is linked vital cellular processes mechanisms metabolism. To elucidate these mechanisms, we carried out genomic biochemical analyses white recessive canary breed, which carries a heritable defect...
Abstract The application of DNA metabarcoding to dietary analysis trophic generalists requires using multiple markers in order overcome problems primer specificity and bias. However, limited attention has been given the integration information from markers, particularly when they partly overlap taxa amplified, vary taxonomic resolution biases. Here, we test use a mix universal specific provide criteria integrate multi‐marker data python script implement such produce single list ingested per...
Sexual dichromatism, a difference in coloration between males and females, may be due to sexual selection for ornamentation mate choice. Here, we show that carotenoid-based dichromatism mosaic canaries, hybrid phenotype arises offspring of the sexually dichromatic red siskin monochromatic is controlled by gene encodes carotenoid-cleaving enzyme β-carotene oxygenase 2 (BCO2). Dichromatism canaries explained differential carotenoid degradation integument, rather than sex-specific variation...
Behavioral differences among individuals are common and organized into personalities in a wide variety of species. Hypotheses for the coexistence behavioral fall 3 categories: variation selection, frequency-dependent plasticity. We tested predictions those hypotheses regarding geographic covariation behavior with ecology, using recent (≈40 years) biological invasion waxbills (Estrilda astrild). Behavior tests exploration social interaction covaried individuals, suggesting syndrome, although...
Knowledge on diet composition of a species is an important step to unveil its ecology and guide conservation actions. This especially for that inhabit remote areas within biodiversity hotspots, with little information about their ecological roles. The emblematic giant wall gecko Cabo Verde, Tarentola gigas, restricted the uninhabited Branco Raso islets, presents two subspecies. It classified as Endangered, locally Extinct Santa Luzia Island; however, known behaviour. In this study, we...
Summary Food webs and trophic dynamics of coastal systems have been the focus intense research throughout world, as they prove to be critical in understanding ecosystem processes functions. However, very few studies undertaken a quantitative comparison entire food from key consumer perspective across broad geographical area, limiting relevant comparisons among with distinct biotic abiotic components. We investigate structure functioning four tidal ecosystems international importance for...
Trophic networks in small isolated islands are a fragile balance, and their disturbance can easily contribute toward the extinction vortex of species. Here, we show, Atlantic island (Raso) Cabo Verde Archipelago, using DNA metabarcoding, extent trophic dependence Endangered giant wall gecko Tarentola gigas on endemic populations vertebrates, including one rarest bird species world, Critically Raso lark Alauda razae. We found that (27%), Iago sparrow Passer iagoensis (12%), Bulwer's petrel...
The diversity of the cloacal microbial community in migratory shorebirds, caught at Tagus estuary, Portugal, was assessed by cultivation (R2A and Nutrient Agar media) denaturing gradient gel electrophoresis profiling (DGGE) to provide a better understanding birds' potential harbor disperse pathogens. Three different bird species belonging four populations were studied: common redshank (Tringa totanus), black-winged stilt (Himantopus himantopus) nominate Icelandic black-tailed godwit (Limosa...
Discrete colour morphs coexisting within a single population are common in nature. In broad range of organisms, sympatric often display major differences other traits, including morphology, physiology or behaviour. Despite the repeated occurrence this phenomenon, our understanding genetics that underlie multi-trait and factors promote long-term maintenance phenotypic variability freely interbreeding incomplete. Here, we investigated genetic basis red black head Gouldian finch (Erythrura...
Abstract Unlike wild and domestic canaries (Serinus canaria), or any of the three dozen species finches in genus Serinus, urucum breed exhibits bright red bills legs. This novel trait offers a unique opportunity to understand mechanisms bare-part coloration birds. To identify mutation producing colorful phenotype, we resequenced genome performed range analyses search for genotype-to-phenotype associations across genome. We identified nonsynonymous gene BCO2 (beta-carotene oxygenase 2, also...
Abstract Although sexual dietary differentiation is well known in birds, it usually linked with significant morphological dimorphism between males and females, lower reported sexually monomorphic or only slightly dimorphic species. However, this may be an artifact of poor taxonomic resolution achieved most conventional studies, which unable to detect subtle intraspecific prey consumption. Here, we show the power multi‐marker metabarcoding address these issues, focusing on a generalist...
Abstract Our commentary explores the increase in cashew cultivation across West Africa, drawing attention to its impacts on biodiversity and livelihoods. We summarize issue regionally, then showcase Guinea‐Bissau, where we unravel dynamics between expansion, habitat loss, Finally, propose concrete policy measures encompassing strengthened conservation, sustainable land‐use planning, enhanced farming practices, community engagement, international market reforms. recommendations extend beyond...
Summary Rice fields provide functional wetlands for declining shorebirds and other waterbirds around the world, but fundamental aspects of their stopover ecology in rice remain unknown. We estimated length stay Black-tailed Godwits Limosa limosa migrating through fields, showed international importance Extremadura’s (south-west Spain) this Near Threatened shorebird species. Overall, large numbers en route to breeding grounds had long lengths (34.7 ± 1.7, 14.4 2.0 8.3 1.2 days godwits...
