AI Article Synopsis
- - The study assessed the genetic diversity and differentiation of four Neoschongastia gallinarum populations using mitochondrial gene sequences, finding high genetic diversity and adaptability among them.
- - Geographic isolation among populations contributed to genetic differentiation, while human trade activities facilitated some gene flow between them.
- - Analysis indicated that genetic variation was primarily within populations, with no clear geographical pattern, and suggested that N. gallinarum populations have remained stable in size without recent expansion.
Article Abstract
The genetic diversity and differentiation of four geographic populations of Neoschongastia gallinarum were evaluated using concatenated mitochondrial gene sequences (pCOI, pCOII, and pND5). Based on the results, the N. gallinarum populations had high genetic diversity and strong ecological adaptability. Genetic differentiation among paired populations calculated using concatenated mitochondrial gene sequences revealed that geographic isolation resulted in genetic differentiation among the populations of N. gallinarum, and gene flow between populations associated with human trade activities. Systematic development and molecular variance based on haplotypes revealed that genetic variation existed in different haplotypes; however, no clear rule related to geographic region was found. Further, genetic variation was mainly derived from individuals within the population. A neutral test based on concatenated mitochondrial gene sequences and nucleotide pair differences revealed that N. gallinarum did not experience an obvious population expansion in recent historical periods. Accordingly, the population size was relatively stable.

Kinetoplastids display a single, large mitochondrion per cell, with their mitochondrial DNA referred to as the kinetoplast. This kinetoplast is a network of concatenated circular molecules comprising a maxicircle (20-64 kb) and up to thousands of minicircles varying in size depending on the species (0.5-10 kb).

Background: Pleuronectiformes, also known as flatfish, are important model and economic animals. However, a comprehensive genome survey of their important organelles, mitochondria, has been limited. Therefore, we aim to analyze the genomic structure, codon preference, nucleotide diversity, selective pressure and repeat sequences, as well as reconstruct the phylogenetic relationship using the mitochondrial genomes of 111 flatfish species.

Black-goggled tanagers Trichothraupis melanops (Vieillot, 1818) are passerine birds commonly observed in the Brazilian Atlantic Forest, Argentina and Paraguay. Tanagers are among the passerines with the highest prevalence and density of coccidian parasites, mainly due to their frugivorous feeding habits that favor fecal-oral transmission. In this context, the current study identifies a new species of Isospora Schneider, 1881 parasitizing black-goggled tanagers captured in the Itatiaia National Park, a protected area with a high degree of vulnerability in Southeastern Brazil.

Introduction: is a freshwater turtle species endemic to northeastern Thailand and Lao PDR. While is relatively common and widespread in Thailand, its population size and demographic trends remain largely unknown, as direct population estimates are lacking. This species faces significant threats from consumption, exploitation, and trade.

Article Synopsis
- A new genus and species named Heterospinus mccordi was identified from cystacanths found in the mesentery of the red swamp crayfish (Procambarus clarkii) in South Carolina.
- Unique morphological traits include a spindle-shaped body, differently sized spines, and specific hook arrangements, with males displaying distinct reproductive structures.
- Genetic analysis showed a 27% divergence from closely related species, supporting the establishment of the new genus and species, marking the first record of polymorphid parasites in this crayfish outside its native habitat.
