This study shows that adaptive evolution in yeast increases ERAD capacity to improve thermotolerance by enhancing proteostasis under thermal stress.

The paper shows that mobile genetic elements in honey bee gut microbiomes show increased sequence diversity with broader host range.

The study uses mitochondrial genome sequencing of museum specimens to assess species diversity within the Channichthys genus, finding high divergence in Charcoal Icefish and suggesting its validity as a distinct species.

The paper identifies leopard cats as the earliest felines in Chinese human settlements, predating domestic cats by over 2,500 years, and traces the arrival of domestic cats via the Silk Road.

This study shows oxygen-binding proteins enhance fitness in larger organisms under high oxygen conditions by improving oxygen diffusion efficiency.

This study examines how sperm production and allocation in black soldier flies respond to varying sperm competition risks, showing adaptive plasticity in reproductive strategies.

The paper models the evolution of human pair bonds by simulating male mating strategies under different sex ratio conditions and finds that higher sex ratios favor mate-guarding over multiple mating.

This study identifies gene regulatory mechanisms that coordinate neuron-type-specific programs with plastic gene expression responses in Caenorhabditis species.

This study uses population-level sampling and 2bRAD sequencing to test the general dynamic model (GDM) in a Mascarene flowering plant radiation, finding that evolutionary processes shift with island age.

The paper replaces orthologous transcription factors in yeast to show that stable TFIIIC complexes are essential for proper mitotic chromosome segregation.

The paper examines how asymmetric migration rates affect local adaptation in a two-habitat model, showing migration can both suppress and facilitate adaptation depending on symmetry.

This study shows ancestral plasticity to salt helped Silene uniflora adapt to zinc in mine-waste environments, demonstrating past-cue plasticity's role in rapid adaptation to novel habitats.

This study examines how flight loss affects feather anatomy in birds, finding increased vane symmetry in flightless species, with more pronounced changes in ancient flightless lineages.

This study compares physical activity levels in BaYaka hunter-gatherer children with US and UK children, finding higher activity in BaYaka children and age-related differences.

This study shows that hummingbird-pollinated Costus species lose floral scent through gene downregulation, not pseudogenization, highlighting strong selection pressures for scent loss.

This study uses comparative population genomics to identify a shared phylogeographic break in seven hydrothermal vent species, revealing patterns of lineage divergence and gene flow in the Southwest Pacific.

This study examines genomic responses of Rhinella horribilis to anthropogenic habitat modification, finding both concordant and unique adaptive patterns in two landscapes.

This study identifies molecular functional convergences in complex multicellular eukaryotes by analyzing genomic and phylogenetic data across 49 species.

This paper investigates the B chromosome in Pseudococcus viburni, identifying its genetic content and mechanisms that allow it to escape paternal genome elimination during meiosis.

This study uses near-infrared spectroscopy to distinguish between wild and lab-reared tsetse flies, achieving 86% accuracy and improving to 88% with irradiation of lab-reared flies.
