Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

The Mediator's Mind: Navigating Party Psychology and Behavioural Dynamics in Dispute Resolution

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Mediation increasingly requires psychological competence, as mediators regulate emotion, cognition and interaction within conflict systems. This study examines how mediators' psychological awareness and behavioural reflexivity shape conflict trajectories, advancing the concept of a behavioural architecture that transforms emotional volatility ...

Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

open access: yesInsect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

Existence of Picard operator and iterated function system

open access: yesApplied General Topology, 2020
<p>In this paper, we define weak θ<sub>m</sub>− contraction mappings and give a new class of Picard operators for such class of mappings on a complete metric space. Also, we obtain some new results on the existence and uniqueness of attractor for a weak θ<sub>m</sub>− iterated multifunction system.

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

open access: yesIntegrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Solving optimal control problems governed by random Navier-Stokes equations using low-rank methods

open access: yes, 2017
Many problems in computational science and engineering are simultaneously characterized by the following challenging issues: uncertainty, nonlinearity, nonstationarity and high dimensionality. Existing numerical techniques for such models would typically

Genetic risk factors in Finnish patients with Fuchs endothelial corneal dystrophy

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To study the genetic risk factors of Fuchs endothelial corneal dystrophy (FECD) in the Finnish population using hospital‐based and large biobank cohorts. Methods We genotyped a cohort of 107 Finnish patients with FECD for the primary associated genetic risk factor, the TCF4 (CTG)>50 expansion, and studied their clinical phenotype.
