The effects of Gambusia affinis on some suspected predators of mosquitoes were studied for a period of 12 months. A list of such predators was given. The most abundant invertebrate predators were Odonata, followed by Hemiptera and Ephemeroptera and the least common were Coleoptera. The population density of mosquito predators, with exception of Notonectidae and the fish Oreochromis niloticus, was markedly reduced in the presence of G. affinis. Application of aerial pesticides reduced the population of both G. affinis and O. niloticus fish. However it had no effect on the numbers of all invertebrate predators.

Human exposure to polycyclic aromatic hydrocarbons (PAH) is a significant public health problem that will worsen with a warming climate and increased large-scale wildfires. Here, we characterize an epigenetic memory at the cytochrome P450 1 A (CYP1A) gene in wild Fundulus heteroclitus that have adapted to chronic, extreme PAH pollution. In wild-type fish, CYP1A is highly induced by PAH.

Reproductive senescence is common across taxa and females often show a predictable decline in fecundity after maturity. Attending to these age-dependent cues could help males make optimal mate choice decisions. Here, we examined reproductive senescence and male mate choice in the androdioecious mangrove rivulus (), where self-fertilizing hermaphrodites exist with rare males.

The mangrove killifish, Kryptolebias marmoratus, can reproduce with self-fertilisation, offering a unique and useful genetic tool for generation of genetic mutants and quick identification of mutated genes. From an ENU-mutated mangrove killifish line R228, we have isolated a novel mutant line, no-fin-ray/nfr in which homozygous mutant of adult fish fin ray development is largely reduced. Illumina RNAseq with 3 embryos each from mutants, siblings and the parental WT strain Hon9 (only 9 embryos as total) identified a mutation in the edaradd in a highly conserved C-terminal death domain.

Plastic pollution threatens almost every ecosystem in the world. Critically, many animals consume plastic, in part because plastic particles often look or smell like food. Plastic ingestion is thus an evolutionary trap, a phenomenon that occurs when cues are decoupled from their previously associated high fitness outcomes.

The main contributor to Türkiye's abundant freshwater fish biodiversity is its geographic location. This fauna consists of endemic, native, and non-native fish species. The introduction of Gambusia holbrooki Girard, 1859 to Lake Amik in the 1920s for the biological control of malaria was the first introduction of nonnative species to Türkiye.
