“…Natural disasters have profound impacts on global biodiversity (Sagar and Singh, 2005 ; Fattorini, 2010 ; Milner et al, 2013 ; Fraver et al, 2017 ; Ohbayashi et al, 2017 ). As a serious natural disturbance (Pickett and White, 1985 ; Hobbs and Huenneke, 1992 ), earthquake is one of the natural disasters that causes ecosystem degradation (Huang et al, 2017 ; Kitada et al, 2017 ; Tsujimoto et al, 2020 ; Kang et al, 2021 ). Such disturbance may greatly threaten the survival and competition of plant species by increasing mortality and changing habitat quality (Sousa, 1984 ; Lai et al, 2007 ; Huang et al, 2017 ; Ohbayashi et al, 2017 ; Tsujimoto et al, 2020 ).…”

Earthquakes occur frequently in fragile alpine grassland areas on the Qinghai-Tibet Plateau (QTP), but few studies have evaluated the impacts of seismo-fault of earthquake on alpine grassland vegetation diversity. In this study, we conducted a field survey of plant communities of alpine grassland along the fault zone in the 7.4 Maduo earthquake occurred on 22 May 2021. Surrounding grassland habitat far from the seismo-fault of earthquake was selected as the control. Plant community metrics around and far from seismic rupture were studied. The results showed that plant community metrics were negatively affected by seismo-fault of earthquake. Species composition around seismo-fault was being shifted from sedges-dominant into forbs-dominant. In addition, the diversity and aboveground biomass were significantly decreased around seismo-fault compared with the control. Our findings highlighted that earthquakes can cause species loss and plant community shift and finally lead to productivity reduction of alpine grassland. Additionally, forbs may be more competitive than other functional groups after the earthquake.

“…6 B ). These estimates correspond to a median age of introgression of roughly 19 and 32 kYA, respectively, based on a generation time of 2.4 years for Pacific herring ( Kitada et al 2017 ; Mikkelsen et al 2018 ). The genomic regions where all Balsfjord haplotypes represent introgression have lower estimates (due to longer introgressed haplotypes) than the respective overall set, both for Atlantic (median age = 2.1*10 3 generations) and Pacific HSRs (median age = 8.5*10 3 generations).…”

Atlantic herring (Clupea harengus) and Pacific herring (C. pallasii) are sister species that split from a common ancestor about 2 million years ago. Balsfjord, a subarctic fjord in Northern Norway, harbors an outpost population of Pacific herring within the range of the Atlantic herring. We used whole genome sequencing to show that gene flow from Atlantic herring into the Balsfjord population has generated a stable hybrid population that has persisted for thousands of generations. The Atlantic herring ancestry in Balsfjord was estimated in the range 25-26%. The old age and large proportion of introgressed regions suggest there are no obvious genetic incompatibilities between species. Introgressed regions were widespread in the genome and large, with some in excess of 1 Mb, and they were overrepresented in low-recombination regions. We show that the distribution of introgressed material is non-random; introgressed sequence blocks in different individuals are shared more often than expected by chance. Furthermore, introgressed regions tend to show elevated divergence (FST) between Atlantic and Pacific herring. Together, our results suggest that introgression of genetic material has facilitated adaptation in the Balsfjord population. The Balsfjord population provides a rare example of a stable interspecies hybrid population that has persisted over thousands of years.

Аннотация. Рассмотрена правомерность применения видовых таксонов рода Cleisthenes. На основе литературных данных показано значительное и достоверное расхождение рыб по морфологии, ставится под сомнение сведение форм «pinetorum» и «herzensteini» в один вид. Представители исследуемого рода, обитающие в водах зал. Сендай (Япония, префектуры Мияги и Фукусима), очевидно, являются Cleisthenes pinetorum. На остальной части ареала рода Cleisthenes обитает C. herzensteini.

Population structure and persistence of Pacific herring following the Great Tohoku earthquake

Abstract: fidelity creates weak but significantly differentiated stable population structure. This process can allow restoration of the genetic characteristics of damaged populations over many generations and can thereby promote the long-term viability of marine fishes that have high gene flow.
