Spectral Sensitivities of Wolf Spider Eyes
=ORNELL UNIVERSITY ~',lC.V~;AL ~ULLE(.~E DEF'ARY~,:ENT OF P~-I:~IOLOGY 1300 YORK AVE.~UE NEW YORK, N.Y. Spectral Sensitivities of Wolf Spider Eyes ROBERT D. DBVOE, RALPH J. W. SMALL, and JANIS E. ZVARGULIS From the Department of Physiology, The Johns Hopkins University School of Medicine, Baltimore, Maryland 21205 ABSTRACT ERG's to spectral lights were recorded from all eyes of intact wolf spiders. Secondary eyes have maximum relative sensitivities at 505-510 nm which are unchanged by chromatic adaptations. Principal eyes have ultraviolet sensitivities which are 10 to 100 times greater at 380 nm than at 505 nm. How- ever, two animals' eyes initially had greater blue-green sensitivities, then in 7 to 10 wk dropped 4 to 6 log units in absolute sensitivity in the visible, less in the ultraviolet. Chromatic adaptations of both types of principal eyes hardly changed relative spectral sensitivities. Small decreases in relative sensitivity in the visible with orange adaptations were possibly retinomotor in origin. Second peaks in ERG waveforms were elicited from ultraviolet-adapted principal eyes by wavelengths 400 nm and longer, and from blue-, yellow-, and orange- adapted secondary eyes by wavelengths 580 nm and longer. The second peaks in waveforms were most likely responses of unilluminated eyes to scattered light. It is concluded that both principal and secondary eyes contain cells with a visual pigment absorbing maximally at 505-510 nm. The variable absolute and ultraviolet sensitivities of principal eyes may be due to a second pigment in the same cells or to an ultraviolet-absorbing accessory pigment which excites the 505 nm absorbing visual pigment by radiationless energy transfer. -
The Metabolism of Subcutaneous Adipose Tissue in the Immediate Postnatal Period of Human Newborns

Developmental Changes in the Metabolism of 14C-(U)-D-Glucose and in Enzyme Activities of Phosphofructo- kinase (PFK; EC. 2.7.1.11) and /3-Hydroxyacyl-CoA Dehydro- genase (HAD; EC. 1.1.1.35) M. NOVAK1351, E. MONKUS, H. WOLF, AND U. STAVE Department of Pediatrics, University of Miami School of Medicine, Miami, Florida, USA, Staedtische Kinderklinik, Kassel, West Germany, and Fels Research Institute, Yellow Springs, Ohio, USA Extract Changes in the in vitro metabolism of subcutaneous adipose tissue have been compared in normal human newborns from 2 hr to 2 weeks of age. A group of healthy adult volunteers was also included. Samples were obtained by using a needle biopsy tech- nique. More of the isotope from uC-(U)-D-glucose was incorporated into triglyc- erides (P < 0.05) and also oxidized by suspensions of adipose cells from infants 2-3 hr of age than in older infants (P < 0.01). The ratio of radioactivity in carbon dioxide to radioactivity in triglyceride was also significantly greater in 2- to 3-hr-old infants than in older neonates (P < 0.05). Thin layer chromatography of the total lipid ex- tract showed the greatest amount of radioactivity in the triglycerides, a small amount in 1,3-digiycerides and 1,2-diglycerides, and a trace in fatty acids and monogiyc- erides. These findings were compared with the developmental changes in two key enzymes: phosphofructokinase (PFK), which represents the glycolytic pathway, and (3-hydroxyacyl-coenzyme A (GoA) dehydrogenase (HAD), which is involved in the P oxidation of fatty acids. -

Why Dolphins Are Not Aquatic Apes

(2014). Why dolphins are not aquatic apes. Animal Behavior and Cognition, 1(1), 1-18. doi: 10.12966/abc.02.01.2014 Abstract - The Social Brain (or Social Intelligence) hypothesis is a very influential theory that ties brain size and, by extension, cognitive ability to the demands of obligate and intense sociality. Initially developed to explain primate brain size evolution, the Social Brain hypothesis has since been applied to a diverse array of other social taxa, both mammalian and avian; its origins as a primate-based hypothesis (especially as articulated by Humphrey, 1976), however, mean that it retains a heavily anthropocentric tinge. This colors the way in which other species are viewed, and their cognitive abilities tested, despite fundamental differences in many aspects of bodily morphology, brain anatomy and behavior. The delphinids are a case in point and, in this review, we demonstrate how the anthropocentric origins of the Social Brain hypothesis have pushed us toward a view of the delphinids as a species of ‗aquatic ape‘. We suggest that a more ecological, embodied/embedded, view of dolphin behavior and psychology undercuts such a view, and will provide a more satisfactory assessment of the natural intelligence the delphinids display. Keywords - Social Brain hypothesis, Delphinids, Primates, Cognition, Behavior, Psychology Tracing the history of ideas, scientific or otherwise, is always interesting, and the social intelligence hypothesis is no exception. -

However, high environmental nitrogen content inhibits nodule development and growth.
