WHEATLY, M.G.*; WOOD, T.J.; RENICK, P.; VERNOOY, J.; TASCHENBERGER, L.; WENDELN, M.: Applying what you learned in CLASS: Transforming biological laboratory education so that it is universally accessible. Creating Laboratory Access for Science Students (The CLASS Project) is an NSF-funded initiative to train educators to develop lab exercises and field trips that are universally accessible […]

Temple, J. G.: Animal Magnetism: Using magnetic stir bars to learn about digestive passage rate in snakes. Snakes, as classic ectotherms, are interesting subjects for studying the relationship between temperature and physiological processes. They are particularly well-suited for studying digestive passage rate given the linear anatomical arrangement of their digestive tracts. In this paper, a […]

MORSE, M.P.: AIBS/Packard Review of High School Biology Instructional Materials Ten sets of instructional materials currently used in high school biology courses across the nation were reviewed by a 9-person team of scientists, science educators and teachers. This team developed the AIBS/Packard review instrument and conducted the review over a period of 18 months. The […]

Pabst, D.A.*; Koopman, H.N.; Rommel, S.A.; Potter, C.W; Read, R.J.; McLellan, W.A.: Ontogenetic allometry and body composition of harbor porpoises Phocoena phocoena from the western north Atlantic North Atlantic harbor porpoises face considerable energetic challenges, as they are relatively small mammals with an intense reproductive schedule and a cold-water habitat. We describe post-natal growth of […]

Prum, R.O.*; Williamson, S.: Models of the developmental determination of feather shape and pigmentation pattern. We present the first explicit theories of the growth of feather shape (the outline of a pennaceous vane) and the determination of within feather pigmentation pattern. The growth of feathers is simulated with a mathematical model based on six growth […]

ESPINOZA, N.R.: Effects of developmental temperature on musculoskeletal growth and jumping performance in the treefrog Hyla chrysoscelis. Several vertebrate species have shown ontogenetic adjustments in the form and material properties of the growing musculoskeletal system to allow the same level of locomotor performance in juveniles and adults. The rate of growth and amount of time […]

ZELDITCH, M.L.*; SHEETS, H.D.; FINK, W.L.: Conservative ontogenetic trajectories: artifacts or data? Most comparative studies support the hypothesis that ontogenetic trajectoriesare historically conservative. The primary basis for this generalization is the typically high correlation between ontogenetic allometric vectors, a measure of their similarity. More than 76% of 233 comparisons yield vector correlations as high as […]

Peter Larson: Chondrocranial development in larval Rana sylvatica (Anura: Ranidae): A morphometric analysis of cranial allometry and ontogenetic shape change This study provides baseline quantitative data on the morphological development of the chondrocranium in a larval anuran. Both linear and geometric morphometric methods are used to quantitatively analyze size related shape change in a complete […]

LANNOO, M.J.*; NANJAPPA, P.; BLACKBURN, L.M.: What Amphibian Malformations Tell Us About Causes Amphibian malformations in northern and eastern regions of North America have generated considerable attention from both the general public and the scientific community. Common malformations of ranid frogs collected by the Minnesota Pollution Control Agency include missing limbs (ectromelia) and multiple limbs […]

BOTTON, M. L.*; LOVELAND, R. E.: The Diminishing Abundance of Horseshoe Crabs in Delaware Bay: Potential Impacts on Migrant Shorebirds Migratory shorebirds on staging areas typically concentrate their feeding on unusually abundant prey species, enabling them to rapidly increase mass prior to the next leg of their migration. Delaware Bay is the most important staging […]
