From the 1860s into the 1920s Edward Sylvester Morse (1838-1925) was a staunch advocate of Darwinian evolution and of science education in the U. S. and likewise for several years in Japan. He had a major impact on the American public’s understanding of evolution, both before and after he became...
Introduction: To study the health status of 200 G6PD enzyme-deficient Sarawak newborns, we compared their birth records to those of non-deficients in terms of low birth weight (LBW). To characterize ethnic groups, we analysed newborns in terms of LBW and G6PD population frequency.
Methods: For this retrospective study, health records...
Since Americans were a minority among the outsiders in Southeast Asia before the twentieth century, a legitimate question is: Why write about them there? There are three sides to the answer. For one, there has been no general account of Americans in nineteenth-century Southeast Asia.¹ In addition, the mistakes of...
A wide variety of organisms show morphologically plastic responses to environmental
stressors but in general these changes are not reversible. Though less common, reversible
morphological structures are shown by a range of species in response to changes in predators,
competitors, or food. Theoretical analysis indicates that reversible plasticity increases fitness...
Species invasions have a range of negative effects on recipient ecosystems, and many occur at a scale and magnitude that preclude complete eradication. When complete extirpation is unlikely with available management resources, an effective strategy may be to suppress invasive populations below levels predicted to cause undesirable ecological change. We...
The Pacific red lionfish has recently invaded Western Atlantic and Caribbean coral reefs, and may become one of the most ecologically harmful marine fish introductions to date. Lionfish possess a broad suite of traits that makes them particularly successful invaders and strong negative interactors with native fauna, including defensive venomous...
What do you say when you have only a minute to explain to a municipal official why keeping track of the number of bird species found in a park may help make decisions about park management? Talk of significant differences among treatments or testing theory will likely meet with glazed...
The proliferation of efficient fishing practices has promoted the depletion of
commercial stocks around the world and caused significant collateral damage to marine
habitats. Recent empirical studies have shown that marine reserves can play an important role
in reversing these effects. Equilibrium metapopulation models predict that networks of marine
reserves...
For the past several decades, amphibian populations have been decreasing
around the globe at an unprecedented rate. Batrachochytrium dendrobatidis (Bd), the fungal
pathogen that causes chytridiomycosis in amphibians, is contributing to amphibian declines.
Natural and anthropogenic environmental factors are hypothesized to contribute to these
declines by reducing the immunocompetence of...
Alarista succina gen. et sp. nov. (Poaceae) is described from a single floret preserved in amber of Tertiary age originating from the Dominican Republic. The new genus is characterized by 1) a narrow winged lemma awn, 2) numerous (as many as 17) lemma nerves, 3) a lengthy rachilla internode (implying...
