Abstract:
... Members of the genus Tylodelphys Diesing, 1850 are endoparasites of fish-eating birds, particularly ciconiids, anhingids, and podicipedids across the globe. Metacercariae of Tylodelphys spp. were collected from the cranial and body cavities of freshwater fishes in central and northern Mexico; adults were recovered from the intestine of two species of freshwater diving birds of the family Podiciped ...

Abstract:
... Examining population genetic structure can reveal patterns of reproductive isolation or population mixing and inform conservation management. Some avian species are predicted to exhibit minimal genetic differentiation among populations as a result of the species high mobility, with habitat specialists tending to show greater fine‐scale genetic structure. To explore the relationship between habitat ...

Abstract:
... The Indian Cormorant (Phalacrocorax fuscicollis) is a common avian piscivore that occurs throughout the Indian subcontinent and east to southern Vietnam. Its evolutionary relationships, however, have remained obscure, largely because of a lack of material available for either osteological or genetic analysis. Here we show using DNA-sequence data from both nuclear and mitochondrial genes that this ...

Abstract:

The high relevance of host‐switching for the diversification of highly host‐specific symbionts (i.e., those commonly inhabiting a single host species) demands a better understanding of host‐switching dynamics at an ecological scale.

During the last glaciation, ending about 12,000 years ago, a wide area of the northern Palearctic was under lasting ice and, consequently, breeding sites for most bird species were not available. At the same time, a high diversi ...

... 1. The objective of the study was to investigate the influence of maternal and parent of origin effects (POE) on genetic variation of Iranian native fowl on economic traits. 2. Studied traits were body weights at birth (BW0), at eight (BW8) and 12 weeks of age (BW12), age (ASM) and weight at sexual maturity (WSM), egg number (EN) and average egg weight (AEW). 3. Several models, including additive, ...

Abstract:
... Usutu virus (USUV) previously restricted to Africa where it caused mild infections, emerged in 2001 in Europe and caused more severe infections among birds and humans with neurological forms, suggesting an adaptation and increasing virulence. This evolution suggests the need to better understand USUV transmission patterns for assessing risks and to develop control strategies. Phylogenetic analysis ...

Abstract:
... West Nile virus (WNV) is an arbovirus causing neuroinvasive disease to humans and equines. Since 2004, lineage 2 WNV strains have been identified in Europe and have been implicated in severe outbreaks, with that of 2018 exceeding the total number from the previous seven years. The aim of this study was to explore the evolutionary process that shapes the genetic diversity of lineage 2 WNV strains ( ...

Abstract:
... We report on the assessment of the level of genetic diversity of the capercaillie in Belarus. This species of birds is a valuable biological resource, and also acts as a natural indicator for the state of large forests and the degree of their disturbance by human activities. Two subspecies of the capercaillie —Tetrao urogallus major (C. L. Brehm, 1831) and Tetrao urogallus pleskei (Stegmann, 1926) ...

Abstract:
... Avian evolution has generated an impressive array of patterns and colors in the ∼10,000 bird species that exist on Earth. Recently, a number of exciting studies have utilized whole-genome sequencing to reveal new details on the genetics of avian plumage color. These findings provide compelling evidence for genes that underlie plumage variation across a wide variety of bird species (e.g., juncos, w ...

Abstract:
... Hybrid zones are particularly valuable for understanding the evolution of partial reproductive isolation between differentiated populations. An increasing number of hybrid zones have been inferred to move over time, but in most such cases zone movement has not been tested with long‐term genomic data. The hybrid zone between Townsend's Warblers (Setophaga townsendi) and Hermit Warblers (S. occident ...

Abstract:
... The monal genus (Lophophorus) is a branch of Phasianidae and its species inhabit the high-altitude mountains of the Qinghai-Tibet Plateau. The Chinese monal, L. lhuysii, is a threatened endemic bird of China that possesses high-altitude adaptability, diversity of plumage color and potentially low reproductive life history. This is the first study to describe the monal genome using next generation ...

Abstract:
... Evolution is driven by natural selection acting on variable phenotypic traits. Understanding the molecular basis of those traits is crucial for elucidating the mechanisms of natural selection. The southern African jackal buzzard (Buteo rufofuscus) displays extreme plumage colour polymorphism, with colouration on the chest varying from dark black to pale white. In a number of birds and other verteb ...
