Ensuring connectedness for the maximum quasi‐clique and densest k‐subgraph problems

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 6, Page 3800-3824, November 2026.
Abstract Given an undirected graph G$G$, a quasi‐clique is a subgraph of G$G$ with density at least γ$\gamma$ (0<γ≤1)$(0 < \gamma \le 1)$. Two optimisation problems can be defined for quasi‐cliques: the maximum quasi‐clique (MQC) problem, which finds a quasi‐clique with maximum vertex cardinality, and the densest k$k$‐subgraph (DKS) problem, which ...

Genomic Variation and Population Structure of Portuguese Native Dog Breeds

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The presence of dogs in Portugal is confirmed by zooarchaeological evidence dating to at least 7600 years ago. The 11 native dog breeds that exist in this territory are therefore the end‐product of a complex evolutionary process. This study characterises the genomic diversity and population structure of 10 native breeds based on whole‐genome ...

A Single Amino Acid Substitution in CspA Increases Germination Sensitivity and Broadens Bile Salt Germinant Specificity in Clostridioides difficile Spores

open access: yesEnvironmental Microbiology, Volume 28, Issue 6, June 2026.
In reservoir‐associated RT033 strains, we observe a natural rewiring of spore germination that lowers the activation threshold and broadens bile‐salt specificity, enabling germination at low germinant levels and in response to typically inhibitory bile‐salts common in animal hosts.

Life‐History and Landscape Context Shaping the Spatial Genetic Structure of the Migratory Amazonian Fish Prochilodus nigricans

open access: yesFreshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The Neotropical migratory fish Prochilodus nigricans plays a critical ecological and socioeconomic role in the Amazon basin. Nevertheless, little is known about its populations and the genetic diversity pattern of the species. In light of this, the current study investigates the spatial genetic structure and diversity of P.

Nonapeptide molecular evolution during the adaptive radiation of Tanganyika cichlids

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 6, June 2026.
Abstract Oxytocin (OT) and vasotocin (VT) are evolutionarily conserved nonapeptides that regulate a wide range of physiological and behavioral processes in vertebrates. Their receptor families have undergone gene duplications that facilitated functional diversification throughout vertebrate evolution.

Not Just a Matter of Space: Integrating Ecological Niche Modeling With Genotype‐Environment Associations Suggests High Maladaptation Risks Under Climate Change for a Microendemic Malagasy Frog

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We integrate ecological niche modeling and genotype‐environment association analyses to jointly assess species responses to climate change in terms of dispersal potential and genetic adaptive capacity, and to estimate maladaptation risk under future scenarios in a microendemic Malagasy frog (Mantidactylus bourgati). ABSTRACT Climate change is impacting
