Diets of Three Sympatric Grebe Species in Lake Titicaca Indicate Possible Dietary Niche Partitioning. [PDF]

Ecol Evol
Lake Titicaca is home to three grebe species whose diets have not been thoroughly studied. In this natural history note, we provide the first description of the diets of these species and how they overlap and differentiate. ABSTRACT Dietary niche partitioning is a fundamental process in community ecology, of interest to both conservationists and ...

The cellular basis of compensatory muscle growth in the teleostOdontesthes bonariensis

Journal of Experimental Biology, 2022
ABSTRACTThis study evaluates white muscle growth and in vivo cell proliferation during a fasting and refeeding trial, using pejerrey (Odontesthes bonariensis) as animal model, in order to better understand the cellular basis governing catch-up growth. Experiments consisted of two groups of fish, a control group continuously fed ad libitum, and a group ...

<i>Lactobacillus</i>-Derived Biosurfactants: Emulsification and Antioxidant Properties in Oil Emulsions. [PDF]

Food Sci Nutr
Extracted biosurfactants from lactobacilli present in traditional yogurt had emulsifying performance in emulsions. Oxidation levels indicated that the emulsions prepared with biosurfactants were significantly less oxidized compared to the control sample. This research introduces the biosurfactants derived from L. plantarum and L.
