Beyond thermoregulation: metabolic function of cetacean blubber in migrating bowhead and beluga whales.

The processes of lipid deposition and utilization, via the gene leptin (Lep), are poorly understood in taxa with varying degrees of adipose storage. This study examines how these systems may have adapted in marine aquatic environments inhabited by…

Increased performance in juvenile baboons is consistent with ontogenetic changes in morphology.

OBJECTIVES: In many primates, the greater proportion of climbing and suspensory behaviors in the juvenile repertoire likely necessitates good grasping capacities. Here, we tested whether very young individuals show near-maximal levels of grasping …

Increased performance in juvenile baboons is consistent with ontogenetic changes in morphology.

In many primates, the greater proportion of climbing and suspensory behaviors in the juvenile repertoire likely necessitates good grasping capacities. Here, we tested whether very young individuals show near-maximal levels of grasping strength, and…

DEVELOPMENTAL ALTERATIONS IN N-METHYL-D-ASPARTATE STIMULATED H-3 NOREPINEPHRINE RELEASE IN RAT-BRAIN CORTEX AND HIPPOCAMPUS

Developmental alterations in N-methyl-D-aspartate (NMDA)-stimulated [H-3]norepinephrine release from rat brain cortical and hippocampal slices were studied. NMDA (10-1000 muM) resulted in a concentration-dependent increase in [H-3]norepinephrine…

Comparative embryology of Delphinapterus leucas (beluga whale), Balaena mysticetus (bowhead whale), and Stenella attenuata (pan-tropical spotted dolphin) (Cetacea: Mammalia)

Embryogenesis of cetaceans (whales, dolphins, porpoises) is best known in Stenella attenuata, the pan-tropical spotted dolphin, based on a remarkably complete and well-studied prenatal ontogenetic series. Our study expands understanding of cetacean…

Ontogeny of effective mechanical advantage in eastern cottontail rabbits (Sylvilagus floridanus)

Juvenile animals must survive in the same environment as adults despite smaller sizes, immature musculoskeletal tissues, general ecological naïveté and other limits of performance. Developmental changes in muscle leverage could constitute one…

Effects of gap position on perceptual gap detection across late childhood and adolescence.

The ability to detect a silent gap within a sound is critical for accurate speech perception, and gap detection has been shown to have an extended developmental trajectory. In certain conditions, the detectability of the gap decreases as the gap is…

Benefits Of Stimulus Exposure: Developmental Learning Independent Of Task Performance

Perceptual learning (training-induced performance improvement) can be elicited by task-irrelevant stimulus exposure in humans. In contrast, task-irrelevant stimulus exposure in animals typically disrupts perception in juveniles while causing little…

Toward Integrated Career Assessment: Using Story To Appraise Career Dispositions And Adaptability

This study examined the validity of using stories to appraise career dispositions and problems associated with career adaptability. Premedical students (63 women, 37 men) wrote narratives about Thematic Apperception Test cards (TAT) and responded to…

Family Interaction Patterns And College Student Career Development

We examined whether and how family interaction patterns relate to role salience and vocational identity in a predominantly Anglo-American college student sample (107 women, 65 men). Results indicated significant links between perceived emotional…

The versatility and paradox of GDF 11.

In addition to its roles in embryonic development, Growth and Differentiation Factor 11 (GDF 11) has recently drawn much interest about its roles in other processes, such as aging. GDF 11 has been shown to play pivotal roles in the rescue of the…

Origin Of Intrafusal Fibers From A Subset Of Primary Myotubes In The Rat

S46, a monoclonal antibody (mAb) specific for the SM-1 and SM-2 isoforms of avian slow myosin heavy chains (MHC), was used to study the earliest stages of development of intrafusal fibers in muscle spindles of the rat hindlimb. Spindles formed only…

Sequences Of Intrafusal Fiber Formation Are Muscle-dependent In Rat Hindlimbs

A rat muscle spindle typically contains four intrafusal fibers - one nuclear bag(2), one nuclear bag, and two nuclear chain fibers. We compared the sequence of formation of the three intrafusal fiber types among the tibialis anterior (TA), soleus…

Late maturation of backward masking in auditory cortex.

Speech perception relies on the accurate resolution of brief, successive sounds that change rapidly over time. Deficits in the perception of such sounds, indicated by a reduced ability to detect signals during auditory backward masking, strongly…

A multidimensional measure of work valences

Work valence is derived from expectancy-valence theory and the literature on children's vocational development and is presumed to be a general appraisal of work that emerges during the childhood period. Work valence serves to promote and inhibit the…

Taking advantage of behavioral changes during development and training to assess sensory coding mechanisms

The relationship between behavioral and neural performance has been explored in adult animals, but rarely during the developmental period when perceptual abilities emerge. We used these naturally occurring changes in auditory perception to evaluate…

Cranial synchondroses of primates at birth.

Cranial synchondroses are cartilaginous joints between basicranial bones or between basicranial bones and septal cartilage, and have been implicated as having a potential active role in determining craniofacial form. However, few studies have…

Dental maturation, eruption, and gingival emergence in the upper jaw of newborn primates.

In this report we provide data on dental eruption and tooth germ maturation at birth in a large sample constituting the broadest array of non-human primates studied to date. Over 100 perinatal primates, obtained from natural captive deaths, were…

MORPHOMETRIC ANALYSIS OF COATED VESICLES IN DEVELOPING RAT MUSCLE-SPINDLES

The incidence of coated vesicles under sarcolemmal surfaces of equatorial, juxtaequatorial and polar regions in developing and adult spindles of the rat soleus muscle was examined by quantitative morphometry of transverse ultrathin sections. Coated…

Highlights of Cetacean Embryology

The embryology of cetaceans documents features that elucidate the interaction between form and function in modern species, as well as their evolution from extinct ones. Prenatal specimens of the dolphin Stenella attenuata demonstrate critical aspects…

The early radiations of cetacea (Mammalia): Evolutionary pattern and developmental correlations

The origin and early evolution of Cetacea (whales, dolphins, and porpoises) is one of the best examples of macroevolution as documented by fossils. Early whales are divided into six families that differ greatly in their habitats, which varied from…
