Sexual vs. asexual reproduction—unisexual vs. bisexual populations—diploid vs. polyploid
biotypes—genetic vs. environmental sex determination: all these natural phenomena are …

While many studies have considered the ability of eDNA to assess animal communities in
lacustrine settings, fewer have considered riverine systems, particularly those spanning the …

The paper presents a review of literature data, supplemented with original observations, on
the presence, establishment, distribution and invasive status of alien fish, amphibian and …

Invasive alien species pose a serious threat to biodiversity. They frequently compete with
native species for resources, resulting in the decline or extinction of the latter. Native crucian …

The introduction of invasive species increases interspecific competition with native species,
especially if the invasive fish have a similar ecological role in the ecosystem. The vacant …

Allopolyploid genomes are divided into compartments called subgenomes that are derived
from lower ploidy ancestors. In African clawed frogs of the subgenus Xenopus (genus …

The widely distributed ray-finned fish genus Carassius is very well known due to its unique
biological characteristics such as polyploidy, clonality, and/or interspecies hybridization …

The morphology of asteriscus, lapillus, and (partly) sagitta is described in gibel and crucian
carps from a small natural pond located in Nizhny Novgorod oblast, Russia. The otolith …

Bisphenol S (BPS) is widely used to replace the known endocrine disruptor BPA in various
products. We evaluated the effect of acute in vivo BPS exposure on oocyte quality …

Successful invasive non-native fish species can cause enormous damage to native
biodiversity. In mainland Europe, the introduction of the gibel carp (Carassius gibelio) has …
