The complete mitochondrial genome of red-fronted parrot (Poicephalus gulielmi) revealed a new gene rearrangement within the order Psittaciformes.

ABSTRACT: Vertebrate mitogenomes are thought to be selected for compactness. Therefore, the increasing number of avian mitogenomes comprising duplicated regions is surprising. Such regions were proposed for at least 26 parrot genera based on the length of PCR products. However, complete mitogenomes with the duplications were shown only for six genera. These duplications evolved probably from the ancestral tRNA^THR/tRNA^PRO/ND6/tRNA^GLU/CR and were subjected to subsequent degeneration. Here, we report the mitogenome of Poicephalus gulielmi (the subfamily Psittacinae) with a unique duplication tRNA^THR/pseudoND6/CR1/tRNA^PRO/ND6/tRNA^GLU/CR2. This region is different from all other identified regions and resembles mostly the arrangements in Amazona and Pionus from the subfamily Arinae.

The first complete mitogenome of red-bellied parrot (Poicephalus rufiventris) resolves phylogenetic status within Psittacidae.

Project description:This paper describes the genomic architecture of a complete mitogenome from a red-bellied parrot (Poicephalus rufiventris). The mitogenome sequence was circular and 15,524 bp in length. Compared to other Psittacidae species, the genome encoded a conserved structure consisting of 13 protein-coding genes (PCGs), two rRNA genes, 21 tRNA genes, and two control regions, however, the mitogenome was missing a part of control region and a tRNA-Leu. The lengths of 12S and 16S ribosomal RNA were 975 bp and 1569 bp, respectively. The overall base composition of the mitogenome of P. rufiventris was dominated by higher AT (51.6%) than GC (48.4%) content. The complete mitogenome sequence determined in this study would be useful to track the deeper evolutionary history and the conservation of P. rufiventris.

Complete mitochondrial genome of chestnut-fronted macaw (Ara severus, Psittaciformes).

Project description:Six genera from Arini tribe form a morphologically diverse group named macaws, which differ from other Arini in the presence of bare facial area. Macaws are further distinguished by the bare face pattern, plumage colouration and body size. Six of the eight macaw species from Ara genus can be easily segregated into three pairs according to their colouration. An exception is Ara severus, which differs from others in their size and morphology. The lack of appropriate molecular markers precludes determination of its phylogenetic position. Therefore, the mitogenome of Ara severus presented in this report will be indispensable to refine these phylogenetic relationships.

Complete mitochondrial genome of bronze-winged parrot (Pionus chalcopterus chalcopterus, Psittaciformes).

Project description:Medium-sized neotropical parrots from Pionus genus are represented by at least eight species. However, their taxonomy should be revised because some external morphological characters together with genetic data recognize 19 taxa. At present, only two mitochondrial markers are available for most of these taxa and obtained phylogenies are not well resolved. Therefore, we sequenced Pionus chalcopterus chalcopterus mitogenome to gain more molecular data required for future studies of the taxonomical status and phylogenetic relationships between Pionus taxa. Performed phylogenetic analyses showed seven monophyletic clades including at least two sequences assigned to one species. However, not all subspecies sequences were monophyletic.

Molecular systematics of the Cape Parrot (Poicephalus robustus): implications for taxonomy and conservation.

Project description:The taxonomic position of the Cape Parrot (Poicephalus robustus robustus) has been the focus of much debate. A number of authors suggest that the Cape Parrot should be viewed as a distinct species separate from the other two P. robustus subspecies (P. r. fuscicollis and P. r. suahelicus). These recommendations were based on morphological, ecological, and behavioural assessments. In this study we investigated the validity of these recommendations using multilocus DNA analyses. We genotyped 138 specimens from five Poicephalus species (P. cryptoxanthus, P. gulielmi, P. meyeri, P. robustus, and P. rueppellii) using 11 microsatellite loci. Additionally, two mitochondrial (cytochrome oxidase I gene and 16S ribosomal RNA) and one nuclear intron (intron 7 of the β-fibrinogen gene) markers were amplified and sequenced. Bayesian clustering analysis and pairwise FST analysis of microsatellite data identified P. r. robustus as genetically distinct from the other P. robustus subspecies. Phylogenetic and molecular clock analyses on sequence data also supported the microsatellite analyses, placing P. r. robustus in a distinct clade separate from the other P. robustus subspecies. Molecular clock analysis places the most recent common ancestor between P. r. robustus and P. r. fuscicollis / P. r. suahelicus at 2.13 to 2.67 million years ago. Our results all support previous recommendations to elevate the Cape Parrot to species level. This will facilitate better planning and implementation of international and local conservation management strategies for the Cape Parrot.

Modelling Red-Crowned Parrot (Psittaciformes: Amazona viridigenalis [Cassin, 1853]) distributions in the Rio Grande Valley of Texas using elevation and vegetation indices and their derivatives.

Project description:Texas Rio Grande Valley Red-crowned Parrots (Psittaciformes: Amazona viridigenalis [Cassin, 1853]) primarily occupy vegetated urban rather than natural areas. We investigated the utility of raw vegetation indices and their derivatives as well as elevation in modelling the Red-crowned parrot's general use, nest site, and roost site habitat distributions. A feature selection algorithm was employed to create and select an ensemble of fine-scale, top-ranked MaxEnt models from optimally-sized, decorrelated subsets of four to seven of 199 potential variables. Variables were ranked post hoc by frequency of appearance and mean permutation importance in top-ranked models. Our ensemble models accurately predicted the three distributions of interest ([Formula: see text] Area Under the Curve [AUC] = 0.904-0.969). Top-ranked variables for different habitat distribution models included: (a) general use-percent cover of preferred ranges of entropy texture of Normalized Difference Vegetation Index (NDVI) values, entropy and contrast textures of NDVI, and elevation; (b) nest site-entropy textures of NDVI and Green-Blue NDVI, and percent cover of preferred range of entropy texture of NDVI values; (c) roost site-percent cover of preferred ranges of entropy texture of NDVI values, contrast texture of NDVI, and entropy texture of Green-Red Normalized Difference Index. Texas Rio Grande Valley Red-crowned Parrot presence was associated with urban areas with high heterogeneity and randomness in the distribution of vegetation and/or its characteristics (e.g., arrangement, type, structure). Maintaining existing preferred vegetation types and incorporating them into new developments should support the persistence of Red-crowned Parrots in southern Texas.

Multiple independent origins of mitochondrial control region duplications in the order Psittaciformes.

Project description:Mitochondrial genomes are generally thought to be under selection for compactness, due to their small size, consistent gene content, and a lack of introns or intergenic spacers. As more animal mitochondrial genomes are fully sequenced, rearrangements and partial duplications are being identified with increasing frequency, particularly in birds (Class Aves). In this study, we investigate the evolutionary history of mitochondrial control region states within the avian order Psittaciformes (parrots and cockatoos). To this aim, we reconstructed a comprehensive multi-locus phylogeny of parrots, used PCR of three diagnostic fragments to classify the mitochondrial control region state as single or duplicated, and mapped these states onto the phylogeny. We further sequenced 44 selected species to validate these inferences of control region state. Ancestral state reconstruction using a range of weighting schemes identified six independent origins of mitochondrial control region duplications within Psittaciformes. Analysis of sequence data showed that varying levels of mitochondrial gene and tRNA homology and degradation were present within a given clade exhibiting duplications. Levels of divergence between control regions within an individual varied from 0-10.9% with the differences occurring mainly between 51 and 225 nucleotides 3' of the goose hairpin in domain I. Further investigations into the fates of duplicated mitochondrial genes, the potential costs and benefits of having a second control region, and the complex relationship between evolutionary rates, selection, and time since duplication are needed to fully explain these patterns in the mitochondrial genome.

Complete mitochondrial genomes of six species of the freshwater red algal order Batrachospermales (Rhodophyta).

Project description:Only two mitochondrial (mt) genomes had been reported in members of the red algal order Batrachospermales, which are confined to freshwater habitats. Additional mt genomes of six representative members (Batrachospermum macrosporum, Kumanoa ambigua, K. mahlacensis, Paralemanea sp., Sheathia arcuata, and Sirodotia delicatula) were sequenced aiming to gain insights on the evolution of their mt genomes from a comparative analysis with other red algal groups. Mt genomes sequenced had the following characteristics: lengths ranging between 24,864 nt and 29,785 nt, 22 to 26 protein-coding genes, G + C contents of 21.3 to 30.7%, number of tRNA of 16 to 37, non-coding DNA from 3.8% to 14.8%. Comparative analysis revealed that mt genomes in Batrachospermales are highly conserved in terms of genome size and gene content and synteny. Phylogenetic analyses based on COI nucleotide data revealed high bootstrap support only for the genera usually recovered in the phylogenetic analyses but no support for supra-generic groups. The insertion of a group II intron carrying an ORF coding for the corresponding intron maturase interrupting the COI gene was observed in Paralamenea sp. and accounted for its larger genome in comparison to the other Batrachospermales mt genomes.

Sex differences in audience effects on anogenital scent marking in the red-fronted lemur.

Project description:How the presence of conspecifics affects scent mark deposition remains an understudied aspect of olfactory communication, even though scent marking occurs in different social contexts. Sex differences in scent-marking behaviour are common, and sex-specific effects of the audience could therefore be expected. We investigated sex differences in intra-group audience effects on anogenital scent marking in four groups of wild red-fronted lemurs (Eulemur rufifrons) by performing focal scent-marking observations. We observed a total of 327 events divided into 223 anogenital scent-marking events and 104 pass-by events (i.e. passage without scent marking). Using a combination of generalised linear mixed models and exponential random graph models, we found that scent marking in red-fronted lemurs is associated with some behavioural flexibility linked to the composition of the audience at the time of scent deposition. In particular, our study revealed sex differences in the audience effects, with males being overall more sensitive to their audience than females. Moreover, we show that these audience effects were dependent on the relative degree of social integration of the focal individual compared to that of individuals in the audience (difference in Composite Sociality Index) as well as the strength of the dyadic affiliative relationship (rank of Dyadic Composite Sociality Index within the group). The audience effects also varied as a function of the audience radius considered. Hence, we showed that scent marking in red-fronted lemurs is associated with some behavioural flexibility linked to the composition of the audience, ascribing red-fronted lemurs' social competence in this context.

Complete mitochondrial genome of Agapornis lilianae (Psittaciformes: Psittacidae), with its phylogenetic analysis.

Project description:In this paper, we reported the complete mitogenome of Agapornis lilianae. A. lilianae mitogenome is 16,720bp base pairs long. The overall base compositions of complete mitogenomes of A. lilianae is 29.66% A, 21.5% T, 34.59% C, 14.25% G. All genes exhibit the typical mitochondrial gene arrangement and transcribing directions. The phylogenetic analysis based on 21 mitochondrial sequence data suggested that A. lilianae are closely related to the same genus specie Agapornis roseicollis. The results obtained here would be useful for the conservation and phylogeny of A. lilianae.
