Fluctuating salinity during development impacts fish productivity

This study shows that fluctuating salinity during development negatively affects fish growth and fecundity, with sex-specific impacts on survival and reproductive success.

Effects of inbreeding and elevated rearing temperatures on strategic sperm production

This study examines how inbreeding and rearing temperature affect sperm production in guppies, finding that only inbred males increase sperm production in response to female presence, especially when females are outbred.

Experimental evidence that investment into ejaculation and mating effort impose different life history trade-offs

This study experimentally demonstrates that mating effort and ejaculation in mosquitofish have distinct life history trade-offs, challenging the assumption of a shared resource pool for reproductive investment.

The role of maternal effects on offspring performance in familiar and novel environments

This study tests maternal effects on offspring performance in seed beetles across familiar and novel environments, finding small maternal effects and no significant genotype-by-environment interactions.
