Abstract Aim The role of migratory birds in the spread parasites is poorly known, part because strategies and behaviours potentially affecting transmission are not easy to study. We investigated dynamics infection by blood through annual cycle a long‐distance Nearctic–Neotropical songbird examine this species dispersing between continents. Location Americas. Taxon Grey‐cheeked Thrush ( Catharus minimus , Aves, Passeriformes, Turdidae), Birds. Methods used molecular microscopy screening...
Abstract Because space‐use patterns are a key aspect of the ecology and distribution species, identifying factors associated with variation in size territories home ranges has been central to studies on population ecology. Space use might vary response extrinsic like habitat quality intrinsic physical condition individual aggressiveness. However, role these poorly documented tropics, particularly high‐elevation bird species. We report home‐range Neotropical Andean bird, gray‐browed brush...
Sonations are sounds that animals produce with structures other than the vocal apparatus for communication. In birds, many sonations usually produced modified flight feathers through diverse kinematic mechanisms. For instance, aeroelastic fluttering of produces tonal sound when airflow exceeds a threshold velocity and induces to oscillate at constant frequency. The Fork-tailed flycatcher (Tyrannus savana) is Neotropical bird both migratory year-round resident subspecies differ in shape outer...
Abstract Twisted-wing insects (Strepsiptera) are an enigmatic order of parasites with unusual life histories and striking sexual dimorphism. Males emerge from hosts as free-living winged adults, while females most species remain endoparasites that retain larval traits. Due to scarce genomic data phylogenetic controversies, Strepsiptera was only recently placed the closest living relative beetles (Coleoptera). Here, we report first PacBio HiFi genome assembly strepsipteran Xenos peckii...

Introduction: since 1996, Colombia began changes in many institutions for increase nutritional level all country. The police was calling Plan Nacional de Alimentacion y Nutricion (PNAN 1996-2005). Methods: our work defined the baseline food security. We were visiting 161 homes 113 living children. sample not randomized. applying ELCSA (Escala Latinoamericana del Caribe Seguridad Alimentaria) is an scale security food, social participation schools and biodiversity countries village....
ABSTRACTThe timing of breeding is a key component the life history birds. In tropics, where avian diversity higher and environmental variability less predictable than in temperate latitudes, phenology patterns are poorly understood, many other life-history traits remain largely unstudied. We describe nest, egg, juvenile plumage, population grey-browed brushfinch (Arremon assimilis assimilis, Passerellidae) from Eastern Andes Colombia. found single bluish-white unmarked egg cup-shaped nest....
