Niche separation of two cryptic species through temperature‐dependent hatching

Ecosphere
Understanding coexistence between species is a central goal in community ecology. In particular, species of cryptic species complexes that often occur in the same habitats and are morphologically almost identical are interesting subjects for the study of

Taxonomic, functional and interspecific response of zooplankton to management practices in carp ponds [PDF]

Scientific Reports
Ecological management practices in fishponds are evolving rapidly, and zooplankton communities provide a reliable indicator of these effects. Over an eight-month period, in nine experimental ponds in the Czech Republic, we assessed the taxonomic ...

Food density drives diet shift of the invasive mysid shrimp, Limnomysis benedeni [PDF]

Ecology and Evolution
Understanding the diet preferences and food selection of invasive species is crucial to better predict their impact on community structure and ecosystem functioning.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non-mammalian Models. [PDF]

Environ Toxicol
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

THE USE OF LIVE FOOD IN REARING OF THE LARVAE OF GRASS CARP CTENOPHARYGODON IDELLA

المجلة العراقية للاستزراع المائي, 2022
The larvae of grass carp Ctenophargodon idella were fed on three types of live food Brachionus calyciflorus, Artemia sp. and Daphnia magna. The study showed that live food is very important to achieve high growth and survival of fish larvae.

Mitochondrial genomes of the freshwater monogonont rotifer Brachionus fernandoi and of two additional B. calyciflorus sensu stricto lineages from Germany and the USA (Rotifera, Brachionidae)

Mitochondrial DNA. Part B. Resources, 2022
The Brachionus calyciflorus species complex was recently subdivided into four species, but genetic resources to resolve phylogenetic relationships within this complex are still lacking.

Variable Fitness Response of Two Rotifer Species Exposed to Microplastics Particles: The Role of Food Quantity and Quality

Toxics, 2021
Plastic pollution is an increasing environmental problem, but a comprehensive understanding of its effect in the environment is still missing. The wide variety of size, shape, and polymer composition of plastics impedes an adequate risk assessment.

Trans-Generational Morphological Trait Plasticity in Parthenogenetic Offspring of Two <i>Brachionus dorcas</i> Morphotypes Induced by <i>Asplanchna</i> Kairomones. [PDF]

Ecol Evol
We compared life‐table parameters and trans‐generation (F0–F12) morphological developmental plasticity induced by Asplanchna kairomones between two Brachionus dorcas morphotypes (long‐posterior spines, LS; short‐posterior spines, SS). The results revealed that the SS offspring employed a synergistic defense combining increased body size and spine ...

Trade-offs between defense and competitive traits in a planktonic predator-prey system. [PDF]

Ecology
Abstract Predator–prey interactions are crucial components of populations and communities. Their dynamics depend on the covariation of traits of the interacting organisms, and there is increasing evidence that intraspecific trade‐off relationships between defense and competitive traits are important drivers of trophic interactions. However, quantifying
