Monophyletic origin of multiple clonal lineages in an asexual fish (Poecilia formosa) [PDF]

open access: yesMolecular Ecology, 2010
AbstractDespite the advantage of avoiding the costs of sexual reproduction, asexual vertebrates are very rare and often considered evolutionarily disadvantaged when compared to sexual species. Asexual species, however, may have advantages when colonizing (new) habitats or competing with sexual counterparts.

Vitamin C Alleviates Oxidative Stress in Silver Carp (Hypophthalmichthys molitrix) Fingerlings Exposed to Toxicity Induced by Temephos and Buprofezin

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
Context Organophosphates and chitin synthesis inhibitor pesticides pose a significant indirect threat to fish populations, necessitating effective remedial measures. Objective Supplementation with vitamin C (Vit C) in fish feed as a counteracting strategy to mitigate pesticides effect was explored in silver carp (Hypophthalmichthys molitrix ...

Fish Pathogens and Associated Zoonotic Risks in Aquaculture: A Global One Health Perspective

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Aquaculture sector is a key contributor to global food and nutritional security, yet its rapid intensification has heightened concerns about the emergence and spread of zoonotic fish pathogens that threaten human, animal and environmental health.

Black spots and female association preferences in a sexual/asexual mating complex ( Poecilia , Poeciliidae, Teleostei) [PDF]

open access: yes, 2018
We investigated whether female association preferences for males are influenced by black spot disease (BSD), a parasite induced change of the host phenotype.

Sex-specific local life-history adaptation in surface- and cave-dwelling Atlantic mollies (Poecilia mexicana) [PDF]

open access: yes, 2016
Cavefishes have long been used as model organisms showcasing adaptive diversification, but does adaptation to caves also facilitate the evolution of reproductive isolation from surface ancestors?

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Differential susceptibility to food stress in neonates of sexual and asexual mollies ( Poecilia , Poeciliidae) [PDF]

open access: yes, 2018
The maintenance of sex is still an evolutionary puzzle given its immediate costs. Stably coexisting complexes of asexually and sexually reproducing forms allow to study mechanisms that balance the costs and benefits of both asexual and sexual ...
