How landscapes of fear affect the songbirds in our backyards
landscapes of fear songbird habitat
2021/8/6
A team of researchers has recently discovered that fear plays an important, unrecognized role in the underdevelopment, and increased vulnerability, of backyard songbirds
Variations in climate conditions affect reproductive success of Antarctic krill, study finds
climate condition reproduction of krill SAM MEI seasonal variation
2021/8/4
Climate conditions play a significant role in the reproductive success of mature female Antarctic krill and are a factor in fluctuations of the population that occur every five to seven years, a new s...
How do herd’s genetic level and milk quality affect performance of dairy farms?
genetic level dairy farm technical efficiency data envelopment analysis fractional regression model
2018/11/23
The effects of genetic level and output quality characteristics on technical efficiency (TE) of dairy farms were studied. The average total relative breeding value (RBV) at herd level was considered a...
Estimation of genetic parameters of fatty acids composition in flesh of market size common carp (Cyprinus carpio L.) and their relation to performance traits revealed that selective breeding can indirectly affect flesh quality
genetic correlations genetic improvement growth heritability slaughtering traits, supplemental feeding

Do ω-3 PUFAs affect insulin resistance in a sex-specific manner? A systematic review and meta-analysis of randomized controlled trials
adults diabetes omega-3 PUFAs DHA EPA insulin resistance insulin sensitivity
2018/12/19
Background: Evidence has suggested that omega-3 (n–3) polyunsaturated fatty acids (PUFAs) improve obesity-induced insulin resistance (IR); however, results from human intervention trials have been equ...
High intake of regular-fat cheese compared with reduced-fat cheese does not affect LDL cholesterol or risk markers of the metabolic syndrome: a randomized controlled trial
saturated fat dairy triglycerides insulin glucose blood lipids
2018/12/14
Background: Regular-fat cheese contains a high amount of saturated fat. Therefore, dietary guidelines in many countries recommend the consumption of reduced-fat cheese as opposed to regular-fat cheese...

Personality Changes Can Affect Fish Body Shape,Locomotion
Personality Changes Fish Body Shape Locomotion
2016/6/12
Evolutionary change in one trait can elicit evolutionary changes in other traits due to genetic correlations. This constrains the independent evolution of traits and can lead to unpredicted ecological...
