Reproduction is often more thermally sensitive than survival. Thus, understanding the thermal sensitivity of reproductive interactions is crucial given global warming. However, it is unknown how temperature influences female control over fertilization after mating (i.e., cryptic female choice). We tested how temperatures relevant to current conditions and climate change projections influence cryptic female choice in a marine fish, Symphodus ocellatus. Under typical conditions, females bias fertilization dynamics to favor dominant males. We find that warmer temperatures decrease female influence on sperm velocity and reduce the expected paternity of dominant males. Our results demonstrate that temperatures relevant to climate change can shift the balance between mate choice and male-male competition. Thus, climate change may influence sexual selection, leading to evolutionary changes in reproductive traits.

Parasite virulence in coinfected hosts: the importance of infection order
When hosts are simultaneously infected by different pathogens, the severity of the disease might be exacerbated compared to hosts harboring single infections. The reasons underlying these changes in parasite virulence are manifold. Here, we investigated the importance for the infection outcome of order and timing of infection. We used a model of rodent coinfection between two parasites that do not...

Empirical validation of the nearly neutral theory at divergence and population genomic scale using 150 mammals genomes
By limiting the efficacy of selection on mutations of small effects, random drift is expected to play a major role in the evolution of genomes. Formalizing this idea, the nearly-neutral theory predicts that the proportion of non-synonymous mutations that are effectively neutral depends negatively on the effective population size (Ne). As a result, the ratio of non-synonymous over synonymous polymo...

Integrating ethnolinguistic and archaeobotanical data to uncover the origin and dispersal of cultivated sorghum in Africa: a genomic perspective
Archaeobotanical evidence suggests that the beginning of cultivation and emergence of domesticated sorghum was located in eastern Sudan during the fourth millennium BCE. Here, we used a genomic approach, together with archaeobotanical and ethnolinguistic data, to refine the spatial and temporal origin and the spread of cultivated sorghum in Africa. We built a probability map of the origin of sorgh...

Recent divergence and microgeographic genetic structure in an endangered Australian songbird: the southern black-throated finch
Anthropogenic habitat loss and climate change threaten global biodiversity. Effective conservation management requires a detailed understanding of geographic structure, genetic diversity, and demography of threatened species. The black-throated finch, Poephila cincta, is an Australian songbird with two subspecies: atropygialis and cincta. The southern subspecies, cincta, has experienced an ~80% ra...

Patterns of gene family evolution and selection across Daphnia
Gene family expansion underlies a host of biological innovations across the tree of life. Understanding why specific gene families expand or contract requires comparative genomic investigations clarifying further how species adapt in the wild. This study investigates the gene family change dynamics within several species of Daphnia, a group of freshwater microcrustaceans that are useful model syst...

The evolution of gene expression in seasonal environments
The biological activities of organisms are closely linked to seasonality. Phenology, the temporal orchestration of biological activities, is governed by gene expression, yet the evolutionary dynamics underlying seasonal gene expression remain unclear. To investigate these dynamics, we compared genome-wide expression dynamics (molecular phenology) in four dominant evergreen Fagaceae species in Asia...

Ancient stickleback genomes reveal the chronology of parallel adaptation
Parallel evolution of traits and their underlying genetic basis is well-studied, however, studies of parallel chronology of adaptive genetic changes remain scarce. Threespine stickleback are a model system for studying parallel evolution. We present genomic data from nine subfossil stickleback bones dated to 14.8-0.7 KYR BP in age. Comparing the four highest coverage genomes, which represent diffe...

Multiple instances of river-lake introgression in the adaptive radiation of sailfin silversides in Wallace's Dreampond
While adaptive radiations significantly contribute to the world\'s biodiversity, much is unknown about the genetic and ecological factors underlying these rapid successions of speciation. It has been suggested that hybridisation can facilitate the speciation process by generating genetic diversity on which diversifying selection can act. Sailfin silverside fishes (Telmatherinidae) in the Malili La...

Evolution under Domestication: Genetic differentiation in black soldier fly (Hermetia illucens) populations subjected to recent selective breeding
The black soldier fly (BSF; Hermetia illucens) is widely utilized in commercial and research applications for waste bioconversion and sustainable protein production. However, prolonged captivity and artificial selection can shape genetic diversity, potentially influencing adaptability and long-term population stability. This study examined how recent selective breeding, genetic drift, and relaxed ...
