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

Integrative Zoology, Volume 20, Issue 5, Page 1047-1055, September 2025.
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.

Functions of Bidirectional Sex Change and Simultaneously Hermaphroditic Phase Gonads in the Monogamous Goby Lubricogobius exiguus

Ethology, Volume 131, Issue 9, Page 94-106, September 2025.
Many fishes can change their sex. The remarkable example, Lubricogobius exiguus, is a goby that can undergo bidirectional sex change with hermaphroditic gonads, containing both developed ovaries and testes (simultaneously hermaphroditic phase gonad). Based on field observations, we demonstrate that the goby experiences frequent social changes, such as ...

Beyond the Binary: Controlling Natural Sex‐Change in Hermaphroditic Fishes

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Sex‐change in hermaphroditic fishes is a complex but natural biological phenomenon that has significant implications for aquaculture fingerling production, selective breeding, and grow‐out. Understanding the physiological, endocrinological, and molecular pathways underlying hermaphroditism in fishes offers unique opportunities to manipulate ...

Single‐Cell Sequencing: A Sharp Sword for Deciphering Biological Innovations and Evolutionary Adaptations in Lower Vertebrates and Invertebrates

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
Single‐cell sequencing sheds light on cellular diversity, development, and immune evolution in fish and invertebrates, offering new insights into environmental adaptation and evolutionary biology. ABSTRACT Single‐cell sequencing (SCS) technology has revolutionized the study of cellular heterogeneity by enabling the exploration of biological processes ...

Ovotesticular differences of sex development: male or female? Case series

Italian Journal of Pediatrics, 2019
Background The choice of the sex of rearing in patients with ovotesticular differences of sex development (OT-DSD) is difficult. The final decision should be given by the patient himself or herself, but families’ opinion is not to neglect especially when

Levels of Sex Steroids in Plethodontid Salamanders: A Comparative Study Within the Genus Aneides

Ecology and Evolution, Volume 14, Issue 11, November 2024.
Species in the salamander genus Aneides (family Plethodontidae) show interesting patterns of sexual dimorphism. Levels of androgens in males and females do not explain the variation observed between species in the degree of dimorphism and monomorphism.

Effects of chitosan and emamectin benzoate on the reproductive system of Eobania vermiculata (Muller) land snails

Egyptian Journal of Biological Pest Control, 2020
The reproductive system of snails represents essential organ that affects snail population size. Therefore, the present research was directed to evaluate the effect of two biopesticides chitosan (Ch) and emamectin benzoate (EMB) LC50 on the reproductive ...

In search of the glow—Three‐dimensional reconstruction of Latia neritoides with specific focus on the mantel cavity (Mollusca; Gastropoda; Hygrophila)

Journal of Zoology, Volume 323, Issue 2, Page 97-113, June 2024.
The unique defence system of Latia neritoides (Gastropoda) involves secretion of a luminescent mucus. More knowledge on this mucus system will be helpful to understand the basic principle of this luminescent biopolymer. The mucus has incredible underwater bonding abilities, opening up new possibilities for adhesives in moist environments. In this study,

A Case of True Hemaphroditism Presenting with Dysgerminoma [PDF]

Journal of Clinical and Diagnostic Research, 2017
The true hermaphroditism represents only 5% of all disorders of sexual differentiation, thus it is one of the rarest varieties. Diagnosis of true hermaphroditism requires the presence of both ovary and testis either as separate organs or combined to form
