Investigating biotic, chemical, and physical drivers of periphyton and invertebrate biomass in boreal streams supporting juvenile Atlantic salmon

The paper investigates biotic, chemical, and physical factors affecting periphyton and invertebrate biomass in boreal streams to understand their impact on juvenile Atlantic salmon.

Reinforcement influences the ability of cryptic female choice to exert conspecific sperm precedence in hybridizing Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)

The paper examines how reinforcement affects conspecific sperm precedence in Atlantic salmon and brown trout, finding that Atlantic salmon lose this ability while brown trout retain it, influenced by female reproductive fluid.

Reproductive fluids enabling cryptic female choice of paternity do not induce concomitant gamete-mediated paternal effects in embryos of hybridizing salmonid fishes

The paper tests if female-modified sperm experience through ovarian fluid affects offspring development in hybridizing salmonid fishes, finding minimal effects compared to hybridization impacts.

Does post-ejaculatory sperm experience prior to fertilization alter offspring performance beyond paternity in an external fertilizing fish?

This study tests whether post-ejaculatory sperm environment affects offspring performance beyond paternity in capelin fish, finding no such effect.

Sexual selection in capelin: endurance rivalry insights from semen quality and regeneration

The paper investigates capelin mating strategies, finding that males can regenerate semen, supporting the endurance rivalry hypothesis despite small testes and unique sperm physiology.
