Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

open access: yesEcography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Systematic reappraisal of species in Phoma section Paraphoma, Pyrenochaeta and Pleurophoma [PDF]

open access: yes, 2010
Sequence data from the 18S nrDNA (SSU) and 28S nrDNA (LSU) regions of isolates of Phoma section Paraphoma were compared with those of representative isolates of the morphologically similar anamorph genera Pleurophoma and Pyrenochaeta and of the type ...

Evolutionary patterns and structural divergence of CENH3 in legumes: Implications for haploid induction breeding

open access: yesGrassland Research, EarlyView.
From structure to application: evolutionary insights and genome editing strategies for CENH3‐mediated haploid induction in legumes. Abstract Background The centromeric histone variant CENH3 is crucial for chromosome segregation and haploid induction in plants, yet its evolutionary patterns in legumes remain poorly characterized. Methods We investigated

Kevinilla, a new velvet ant genus in the Sphaeropthalminae (Hymenoptera: Mutillidae)

open access: yesEuropean Journal of Entomology
The new genus Kevinilla Bartholomay & Cambra includes the following four Neotropical species: Kevinilla ludovica (Cameron, 1895) comb. n. (the type species), K. bicarinata (Cambra & Quintero, 2008) comb. n., K.

Origin of the Jews and the Arabs: Date of their Most Recent Common Ancestor is Written in their Y-Chromosomes - However, There Were Two of Them [PDF]

open access: yes, 2010
A pattern of Y-chromosomal mutations in 37 and 67 marker haplotypes of the Jews and the Arabs indicates that their most recent common ancestor in haplogroup J1 (subclade J1e*) and that (a different one) in haplogroup J2 (subclade J2a*) lived 4300+/-500 ...

Molecular phylogenetic and morphological analyses revealed a new species, Leucocoprinus roseus (Agaricaceae, Basidiomycota), from Punjab, Pakistan

open access: yesNordic Journal of Botany, EarlyView.
In this article, we describe a new fungal species, Leucocoprinus roseus, collected in Canal View Park, District Mandi Bahauddin, Punjab, Pakistan. The species is proposed as new based on detailed morphological observations and molecular phylogenetic analysis using nuclear ribosomal DNA internal transcribed spacer (nrITS) sequences.

Mitochondrial DNA analysis of eneolithic trypillians from Ukraine reveals neolithic farming genetic roots [PDF]

open access: yes, 2017
The agricultural revolution in Eastern Europe began in the Eneolithic with the Cucuteni-Trypillia culture complex. In Ukraine, the Trypillian culture (TC) existed for over two millennia (ca. 5,400–2,700 BCE) and left a wealth of artifacts.

Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

open access: yesPest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...
