Reproductive biology of female titi monkeys (Callicebus moloch) in captivity.
Titi monkeys (Callicebus spp., Cebidae) are monogamous neotropical primates that live in family-like groups typically consisting of an adult monogamous pair and one or two young. Knowledge about the reproductive biology of this genus is scanty. This study investigated the reproductive biology of female dusky titi monkeys (Callicebus moloch).

متن کاملEffects of rubberized flooring on Asian elephant behavior in captivity.
Six Asian elephants at the Oregon Zoo were observed to determine the effects of a poured rubber flooring substrate on captive Asian elephant behavior. Room utilization also was evaluated in seven rooms used for indoor housing, including Front and Back observation areas. Data were collected in three phases. Phase I (Baseline Phase) examined elephant behavior on old concrete floors. In Phase II (...
متن کاملSimple Preparation of Pacific Cod Trypsin for Enzymatic Peptide Synthesis
Trypsin from the pyloric caeca of Pacific cod (Gadus macrocephalus) was easily prepared by affinity chromatography on Benzamidine Sepharose 6B and gel filtration on Superdex 75. Pacific cod trypsin was composed of three isozymes, and their molecular masses were estimated 23,756.34 Da, 23,939.62 Da, and 24,114.81 Da by desorption/ionization time-of-flight mass spectroscopy (MALDI/TOF-MS) and the...
متن کاملTemperature Effects on Recovery of Pacific Cod Following Exhaustive Exercise
We examined post-exhaustive exercise recovery in Pacific cod acclimated to either 2oC or 7oC. We collected blood samples prior to an exhaustive swimming protocol, immediately after and up to four hours of recovery. Plasma concentrations of cortisol, glucose, lactate, Na+, and Cl– were determined. Concentrations of cortisol, glucose, and lactate significantly increased post-swim as compared to s...
