AI Article Synopsis
- Abouheif developed a test for detecting phylogenetic signals in traits using a modified Moran's I statistic and introduced two new matrices of phylogenetic proximities (matrix A and matrix M).
- Matrix A integrates methods from Abouheif, Moran, and Geary, while matrix M is relevant for biodiversity studies, improving the analysis of phylogenetic autocorrelation.
- Simulations show that matrices A and M offer better power and reduced type-I error compared to common phylogenetic proximity matrices, making them effective for analyzing unresolved phylogenetic trees; data and methods are available online.
Article Abstract
Abouheif adapted a test for serial independence to detect a phylogenetic signal in phenotypic traits. We provide the exact analytic value of this test, revealing that it uses Moran's I statistic with a new matrix of phylogenetic proximities. We introduce then two new matrices of phylogenetic proximities highlighting their mathematical properties: matrix A which is used in Abouheif test and matrix M which is related to A and biodiversity studies. Matrix A unifies the tests developed by Abouheif, Moran and Geary. We discuss the advantages of matrices A and M over three widely used phylogenetic proximity matrices through simulations evaluating power and type-I error of tests for phylogenetic autocorrelation. We conclude that A enhances the power of Moran's test and is useful for unresolved trees. Data sets and routines are freely available in an online package and explained in an online supplementary file.

The Trypanosomatidae family encompasses around 24 genera of unicellular protozoans, many of which are transmitted by various hematophagous arthropods, particularly members of the Orders Diptera and Hemiptera. Fleas and ticks-an understudied group of ectoparasites-have been shown to be hosts of a wide and crescent variety of trypanosomatid species. Further, fleas and ticks of companion animals have been particularly neglected in trypanosomatid surveillance despite the proximity to human populations and the anthropophagous habits of many of these arthropods, which can potentially act as vectors of zoonotic trypanosomatids.

This study investigates the Y-chromosome genetic diversity of the Turkmen population in Turkmenistan, analyzing 23 Y-STR loci for the first time in a sample of 100 individuals. Combined with comparative data from Turkmen populations in Afghanistan, Iran, Iraq, Russia, and Uzbekistan, this analysis offers insights into the genetic structure and relationships among Turkmen populations across regions across Central Asia and the Near East. High haplotype diversity in the Turkmen of Turkmenistan is shaped by founder effects (lineage expansions) from distinct haplogroups, with haplogroups Q and R1a predominating.

Bluetongue (BT) is a viral vector borne disease primarily affecting ruminants such as sheep, cattle, and goats. On 3 September 2023, the Netherlands reported the first case of bluetongue virus serotype 3 (BTV-3/NET2023)), after being BTV free for eleven years. Vaccination with inactivated BT vaccines for serotype 3 has been applied in the Netherlands since May 2024.

In China, medicinal with double flowers (DFs) does not produce seeds, yet it possesses significantly higher paeoniflorin content compared with its single-flowered counterpart. The propagation of medicinal with DFs relies solely on rhizomes. However, due to economic motivations, the rhizomes of medicinal with single flowers (SFs) are often mixed with those of medicinal with DFs.
