Digest: Phenotypic plasticity and the genomic signature of novel castes: insights from soldier evolution in Cephalotes [0.03%]
述评:表型可塑性与新品级的基因组印记——来自Cephalotes蚁属兵级进化的启示

Phenotypic plasticity can alter evolutionary dynamics, but its genomic consequences remain contested. Barkdull & Moreau (2025) combine comparative genomics and developmental transcriptomics in Cephalotes turtle ants to show that the repeate...
High Competition and Selective Extinction: How Biotic and Abiotic Drivers Shaped Speciation and Extinction Regimes in Carnivora [0.03%]
高竞争与选择性灭绝:生物和非生物驱动因素如何塑造食肉目物种形成和灭绝格局

Understanding the drivers of biodiversity over time is a central goal in macroevolution. Yet, the relative contributions of biotic and abiotic mechanisms remain unclear, especially at broader phylogenetic and spatial scales. This study inve...

Polyandry is prevalent, but the optimal patterns of mating for females remain poorly understood despite their importance for our understanding of sexual selection. We therefore performed a meta-analysis on the female fitness consequences of...
Evolutionary history of delayed plumage maturation in manakins (Aves: Pipridae) [0.03%]
曼尼金科鸟类(鸟纲:雀鸟科)晚熟表型的进化历史研究

Avian plumage maturation involves replacing feathers, via discrete molts, until reaching an iteratively-regenerated definitive plumage. In most birds, this process takes about one year. In the Neotropical lekking manakins (Pipridae), males ...
Spatially structured host genetic diversity leads to the evolution of local specialization [0.03%]
空间结构的宿主遗传多样性导致局部特化的进化
Elisa Visher,Anisha Ali,Jonathan Barajas et al.
Elisa Visher et al.
Host heterogeneity and spatial population structure each influence parasite evolution and may interact when space structures contacts between host types. Here, we experimentally evolve granulosis virus in microcosms of its natural Plodia in...
Replicate avian hybrid zones reveal the progression of genetic and trait introgression through time [0.03%]
通过鸟类杂交带的复制揭示遗传和性状渐渗随时间的变化规律
María Isabel Castaño,Elizabeth Croyle,Carlos Daniel Cadena et al.
María Isabel Castaño et al.
Replicate hybrid zones between the same taxa provide a unique opportunity to assess the repeatability of the outcome of interspecific matings by uncovering recurrent genomic and phenotypic introgression patterns. Replicates also facilitate ...
Statistical decomposition of passive and active phenotypic plasticity in traits under homeostatic regulation [0.03%]
稳态调节性状被动和主动表型可塑性的统计分解
Sigurd Einum,Tim Burton
Sigurd Einum
Traits subject to homeostatic regulation exhibit both active and passive phenotypic plasticity, where trait dynamics are shaped by passive effects of the environment and active physiological regulation. We present a model that decomposes th...
Female reed warblers in social pairs with low MHC dissimilarity achieve higher MHC dissimilarity through random extra-pair mating [0.03%]
在社会配对中携带低MHC差异等位基因的雌性草莺通过随机额外求偶实现更高的MHC差异等位基因携带率

Lucyna Halupka et al.
Major Histocompatibility Complex (MHC) polymorphism is maintained by balancing selection through host-pathogen interactions and mate choice. MHC-based mate choice has been investigated across a wide range of vertebrates, and an established ...
Additive genetic variance for fitness maintained by balancing selection [0.03%]
稳定的平衡选择使适应性具有的加性遗传变异得以保持
Tim Connallon,Peter Czuppon
Tim Connallon
Levels of additive genetic variation for fitness (${{V}_A}( w )$) and its components (e.g., viability, fertility) appear to be high in nature, substantially exceeding levels attributable to deleterious mutations at mutation-selection balanc...
Conservation of sensory pathways implies a localised change in the mushroom bodies is associated with cognitive evolution in Heliconius butterflies [0.03%]
感觉通路的保守性暗示了在虹彩凤蝶中蘑菇体的局部变化与认知进化有关
Elizabeth A Hodge,Denise D DellAglio,Antoine Couto et al.
Elizabeth A Hodge et al.
Evolution of novel behaviour is reflected in changes in sensory investment or integration, but the exact nature of these changes is often unclear. The Neotropical butterfly tribe, Heliconiini, offer an attractive system for studying how beh...
