This study aimed to assess the effect of constant darkness applied fish during controlled breeding on reproductive traits in domesticated females Eurasian perch. Based assumption that keeping reproduction operation may reduce stress, suspected be responsible for variable spawning effectiveness this species. Two conditions were assessed (16 h light per day [group 16L] and 0L], two tank replicate...
Abstract A mechanistic understanding of how environmental change affects trophic ecology fish at the individual and population level remains elusive. To address this, we conducted a space-for-time approach incorporating gradients (temperature, precipitation nutrients), lake morphometry (visibility, depth area), communities (richness, competition predation), prey availability (richness density) ...
Vertebrates' diets profoundly influence the composition of symbiotic gut microbial communities. Studies documenting diet-microbiota associations typically focus on univariate or categorical diet variables. However, in nature individuals often consume diverse combinations of foods. If diet components act independently, each providing distinct microbial colonists or nutrients, we expect a positiv...
