Abstract:
... A 35-day experiment was conducted with a total of 105 rainbow trout (Oncorhynchus mykiss) with an average initial weight of 192.9 g, sampled over four time points (day 7, 14, 21, and 28) to study the relationship between respectively, δ¹³C in muscle, liver, and adipose fin and relative weight gain, when fed a diet based on plant C3 ingredients, with a lower level of δ¹³C compared to the baseline d ...

Abstract:
... The physiological mechanisms underpinning adaptations to starvation and cold stresses have been extensively studied in Drosophila, yet the understanding of correlated changes in stress-related and life-history traits, as well as the energetics of stress tolerance, still remains elusive. To answer the questions empirically in this context, we allowed D. melanogaster to evolve for either increased s ...

... Cannibalism is a commonly found behaviour in the animal kingdom. The biggest concern of cannibalism is that it reduces the inclusive fitness of the cannibals by eliminating close relatives. Kin recognition is a strategy used by many cannibals to benefit from cannibalism without the cost of reducing their inclusive fitness by eating close relatives. Most members of the family Phytoseiidae are canni ...
