The transformer gene controls sexual development in Drosophila suzukii

Insect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

To self or not to self? Absence of mate choice despite costly outcrossing in the fungus Podospora anserina

Journal of Evolutionary Biology, Volume 36, Issue 1, Page 238-250, January 2023., 2023
Two Podospora anserina mycelia growing in contact. The position of fruiting bodies (black dots) forming rings away from the contact zone indicates the absence of outcrossing between the two mycelia. Abstract Fungi have a large potential for flexibility in their mode of sexual reproduction, resulting in mating systems ranging from haploid selfing to ...

Occurrence of Intersex in the Marine Mussel Perumytilus purpuratus (Mollusca: Bivalvia): Does Gonadal Parasitism Play a Role?

Biology
Intersexuality is a reproductive phenomenon that occurs in some gonochoric species and refers to the simultaneous presence of both male and female gametes within the same individual.

Shifting microbial communities in acidified seawaters: insights from polychaetes living in the CO2 vent of Ischia, Italy

Integrative Zoology, EarlyView.
The microbiome of polychaetes Syllis prolifera and Platynereis massiliensis complex changes in naturally acidified CO2 vents. A slight degree of acidification is associated with relevant changes in the microbial community, stressing the importance of investigations about the possible effects of ocean acidification on key biological and ecological ...

Interpopulation variation in inbreeding is primarily driven by tolerance of mating with relatives in a spermcasting invertebrate

Journal of Evolutionary Biology, Volume 36, Issue 1, Page 95-108, January 2023., 2023
The spermcasting colonial ascidian Lissoclinum verrilli. Through a natural experiment, we found that L. verrilli tolerates relatives as mates in demographically isolated populations. Abstract The degree to which individuals inbreed is a fundamental aspect of population biology shaped by both passive and active processes. Yet, the relative influences of

Molecular Method Based on Hydrolysis Probe Assays to Identify the Sex Chromosomes of Iberian Desman (Galemys pyrenaicus) Using Non‐Invasive Sampling

Integrative Zoology, EarlyView.
To monitor populations of an endangered species such as Galemys pyrenaicus in the Extremadura area, qPCR techniques have been used to determine sex, using non‐invasive sampling techniques. ABSTRACT Desmans belong to the subfamily Desmaninae, which are members of the family Talpidae.

Handbook of protocols for standardized measurements of floral traits for pollinators in temperate communities

Methods in Ecology and Evolution, EarlyView.
Abstract Floral traits describe organs or structures directly related to plant reproduction, and they are essential to understanding plant–pollinator interactions, notably for conservation purposes. The growth of plant trait‐based approaches lies in the availability of data shared by the international research community on dedicated platforms, as well ...

Genome-Wide Association Study Reveals Genetic Mechanisms Underlying Intersex and Aproctia in Large White Pigs

Animals
Congenital developmental abnormalities in piglets, such as intersex and aproctia, adversely affect survival rates, growth performance, and genetic breeding efficiency in pig populations.

Optimising Age‐Specific Insulin Signalling to Slow Down Reproductive Ageing Increases Fitness in Different Nutritional Environments

Aging Cell, EarlyView.
We found that reducing insulin signalling in adult worms slows down their reproductive ageing and extends their lifespan without negative side effects. Moreover, combining it with IF further enhances these benefits. These interventions likely work by regulating genes linked to biosynthesis and immunity, showing how optimising gene expression can delay ...
