🌊 New Publication Alert! 🐟 Thrilled to share our latest study on fish growth and health in the Chirchik River, a key tributary of the Syr Darya in Central Asia. 📌 We assessed length–weight relationships (LWR) and condition factors (Kn and K) of five freshwater fish species—2 native, 3 invasive—from upper and middle reaches of the river. ✅ Positive and isometric growth patterns suggest healthy habitats. 📈 Relative condition (Kn) showed stable physiological status. ⚖️ But Fulton’s condition factor (K) revealed interspecies differences in energy use and body form. 📚 This research offers crucial baseline data for conservation and monitoring in human-impacted Central Asian rivers and highlights the power of biometric tools to evaluate freshwater ecosystem health.

Had a fantastic weather, spectacular scene and sun ☀️. Enjoyed the Saturday with colleague from Sweden 🇸🇪 at the Great Wall in Beijing. https://t.me/EvolutionaryGenomics

The 10th International Symposium on Sturgeon is over with marvelous talks, met with many friends and colleagues. Thanks to organizers! 19-24 October Yichang, China Chinese Three Gorges University https://t.me/EvolutionaryGenomics

Grateful to present at the 10th International Symposium on Sturgeons in Yichang, China. In my talk, I shared urgent findings on the Amu Darya false shovelnose sturgeons (Pseudoscaphirhynchus kaufmanniand P. hermanni), highlighting: 🔻Distribution collapse across their historical range 📉Body size reductions and altered biometric patterns 🧬Decreasing genetic diversity, signaling long-term population decline ⚠️Cultural drivers of poaching, including beliefs and traditions fueling illegal exploitation These species are facing a multidimensional crisis. Without immediate action—biological, institutional, and cultural—we risk losing them forever. Thanks to the organizers and colleagues who continue to lead critical conversations around sturgeon survival and river conservation. https://t.me/EvolutionaryGenomics

Today, I’m heading to the 10th International Symposium on Sturgeons in Yichang, China — a premier global academic forum dedicated to sturgeon research, covering their biology, ecology, aquaculture, and genetics. The symposium is organized by Wuhan University, in collaboration with China Three Gorges University and the National Engineering Research Center of Eco-Environment in the Yangtze River Economic Belt, part of China Three Gorges Corporation. As a member of the IUCN SSC Sturgeon Specialist Group representing Central Asia, I will present the latest findings on the Amu Darya false shovelnose sturgeons (Pseudoscaphirhynchus kaufmanni and P. hermanni). My talk will provide up-to-date insights into their distribution, trends in major biometric indices, genetic diversity, key threats, and our ongoing captive breeding efforts. Additionally, the IUCN Sturgeon Specialist Group will address recent concerns in sturgeon taxonomy and upcoming conservation assessments. #ISS10 #Sturgeon #Pseudoscaphirhynchus

It is a year to acknowledge Japanese scientists, two scholars in field of medicine and chemistry have been awarded with Nobel Prize. Shimon Sakaguchi - in medicine or physiology Susumu Kitagawa - in chemistry https://t.me/EvolutionaryGenomics

What is adaptive radiation? Adaptive variation is a rapid evolution of a single species or lineage into multiple species. The major driver of adaptive variation is habitat heterogeneity, adaption to different food sources, or ecological niches. https://t.me/EvolutionaryGenomics

Genomic islands of speciation separate cichlid ecomorphs in an East African crater lake. The term species is still controversial, and scientists mostly describe species by means of morphological features, and several DNA markers (mt vs. nuclear). Basically, any morphological signal is associated with correspond gene in DNA. But finding the outliers of this gene between comparison group is complicated. And sometimes, species with high morphological differences may possess extremely low genetic differences, making it difficult to convince species delimitation. Sometimes, vice versa. Another paradox is that there is no threshold for morphological variation for species, like how many traits should differ, or at which stage of difference we should recognize several species. Thus, in the era of genomics, we integrate morphology with genomics, and answer those challenges questions. The above paper, is one of the highly cited example for how to navigate genomics and morphology for speciation.

What distinguishes a Nature-level paper from mid-quality papers is that their simplicity. Before starting my PhD journey, I had not much interest in to read papers published in Cell, Nature, Science and PNAS. Publishing or writing such advanced papers does not require only outstanding results, but also needs storytelling ability, forwarding your news in simple, human readable and logical way.
